How to install Windows 7 on Windows 8 laptop?



Step 1

Using Disk Management to create a partition for Windows 7:

1) Open Windows 8’s ‘Disk Management’ (press and hold the ‘Windows’ key and tap the X key). Then select the ‘Disk Management’ (or tap the ‘K’ key) option from the list.


2) Change the ‘Volume name’ to “Windows 8 Pro” (Without the quotes). Right click on the Windows 8 partition (C:) and select ‘Properties’. In the ‘General’ tab change the existing name to: Windows 8 Pro and click the ‘Apply’ button.


3) Shrink the Windows 8 partition to create unallocated space for use when installing Windows 7. Right click on the Windows 8 partition (C:) and select the ‘Shrink Volume’ option. Now enter a value for the amount of space to shrink in MB. For the 931GB partition in this example I wanted to create a 460GB partition for Windows 7, so I entered a value of 471040 (460 X 1024). If your Windows 8 partition contains a lot of data you want to consider a smaller partition size for Windows 7 (75 to 100GB).


Click the ‘Shrink’ button to start the process. After the shrink operation has completed you will see 460.00GB in “Unallocated” space.


4) Create a “Primary” partition and format it. Right click on the unallocated space and select ‘New Simple Volume’.


In the “Format Partition” window you want an ‘NTFS’ partition, leave the allocation unit size set to ‘Default’ and either choose a ‘Quick’ or ‘Full’ format. I prefer a full format (takes longer to complete, but it’s safer) so as the screenshot below shows, the ‘Perform a quick format’ option is unchecked. Click ‘Next’ to continue.


5) Change the volume name to Windows 7 (or Windows 7 Pro or Windows 7 Ult if Home Premium is not what you are installing). This will make it easy for you to select the proper location on the drive during the Windows 7 installation process.

Step 2


Restart the computer. In Windows 8, from the Start or Desktop screen move your pointer over the upper or lower right corner of the screen. When the Windows Charms appear, click the Settings ( ) charm, click Power, and then the Restart option.
Press and hold the F2 key when the screen goes black, and wait for the BIOS setup utility to launch. If your system cannot boot into Windows 8, shut down the computer completely, then press F2 while powering back on.
Select Security -> Secure Boot, and then Disabled.
Select Advanced -> System Configuration, and then Boot Mode.
Change UEFI Boot to CSM Boot.
To save the change and exit the BIOS setup, press F10.

Note : Step 2 is for to boot system from CD/DVD or USB.


That's All .. Let me know if any issue comes on the way.

Thanks :)

What is Joining/Acceptance Letter?

A letter from the applicant indicating his wiliness to accept the job is offered by an employer. It may include an acknowledgement of having appointment letter also. Even if you have accepted a job over the phone, it’s a good idea to write a job acceptance letter to confirm the details of employment and to formally accept the job offer.

An appointment letter/verbal appointment would typically include the following:

·         A thank you for the candidate’s interest in the job.
·         Why the candidate is qualified for the position.
·         Deadline of the offer.
·         What the candidate should do if s/he have any question(s).
·         Their offer details including salary and other benefits.

Address the letter to the person who offered you the position including your contact information. Make sure that your letter is well written and does not contain typos or grammatical errors. Even though you already have been offered the job, you want to make sure all your correspondence is professional.

Sample Joining/Acceptance Letter

This is a sample acceptance letter to give you an idea on how to write your own letter. The phrases are in capital letters, italic and surrounded by third brackets ‘[]’ should be replaced by your own information.

How the Transport Layer Works



The Transport layer- is the layer responsible for actually getting the data packets to a specific location. When we receive email, we want to open it with our email program- not anything else. So how does a computer know exactly where to route data to appropriate programs, all while dealing with multiple connections?

The Difference between TCP and UDP

There are two protocols that are primarily used to transport data: TCP and UDP. TCP stands for transmission control protocol. It is the more common of the two, since it allows for much more error checking functionality and stability. UDP, or User Datagram Protocol, lacks extensive error checking- but is considered to be much faster than TCP as a result.
Since TCP guarantees the delivery of data over a network we call it a connection-oriented protocol. If in the event that data isn’t sent correctly, the sending computer will be notified and will resend the information. This is compared to UDP, which doesn’t require that data has been received correctly. Likewise, we call UDP a connectionless protocol.

How Do Transport Protocols Work?

We mentioned earlier that a transport protocol can have simultaneous connections to a computer- yet the receiving computer still knows where each data packet should be sent. This is accomplished through ports and sockets.

A port is simply an internal address that acts as a pathway to control data flow. Since we need each port to be specific to a certain application, there are thousands of ports for use. If you are using the internet, for instance, data is being routed through TCP port 80. This port is called the HTTP port. Ports that have specific purposes (such as the HTTP port) are also known as well-known ports. (And in case you were wondering, there are over 65,535 ports to experiment with.
So now we know two things. First, the IP address is used to route the data to a specific computer. Next, the port number is used to tell the receiving computer what kind of application should handle it. But to actually accomplish both of these tasks, we use what is called a socket. A socket is simply an address formed by using the IP address and then tacking on the port number at the end.
Practical Uses of the Socket


So what good is a socket? For one thing, multiplexing and demultiplexing is made possible. When you are running multiple programs that are communicating with other computers, you are making use of both of these technologies.

Let’s look at a practical example. You are running a telnet server in which multiple computers are connected to. Each computer uses a socket address to tell the server which computer and which port the data is coming from. If each computer broadcasted at the same time, there may be a jam at the transport layer. We use multiplexing in this case to combine all incoming data into one stream.
Demultiplexing is very similar to multiplexing, except that it works in reverse. Instead of taking multiple streams of input data and outputting a single stream of data, demultiplexing involves receiving a single stream of input and delivering it to multiple outputs. This is handy for separating multiplexed signals. You may see demultiplexing referred to as “Demuxing.”

The Anatomy of a TCP Segment

So now we know how data is routed, but what is the data made up of? As we learned in previous sections, we call the data at the Transport level of the TCP protocol a segment.

TCP Segments Explained


1. Source Port - A 16-bit field that specifies which port number the data segment originated from on the source machine.

2. Destination Port - A 16-bit field that specifies which port number the data segment is destined for on the receiving machine.

3. Sequence Number - A 32-bit field that specifies which sequence number the particular segment of information is assigned. The sequence number is used to number packets of information so that they may be counted on the receiving side- guaranteeing a successful and complete delivery of information.

4. Acknowledgment Number - A 32 bit field that specifies whether or not a segment was received correctly. The acknowledgment number is always one higher than the sequence number, since the receiving computer is expecting the next segment.

5. Data Offset – A 4-bit field that tells the receiving computer how long the header is, and where the data actually begins.

6. Reserved - A 6-bit field that is reserved for future use. Currently this field is represented as all zeroes. In the future, it may be likely that TCP will make use of this space for some reason or another.

7. URG - A 1-bit control flag that stands for urgent. If the value is 1, the information is urgent and should be dealt with accordingly.

8. ACK - A 1-bit control flag that, if set to 1, indicates that the Acknowledgment Number field is significant.

9. PSH - A 1-bit control flag that stands for push. If set to 1, all the information sent so far is sent to the receiving application.

10. RST - 1-bit control flag that stands for reset. If set to 1, the connection is reset.

11. SYN - A 1-bit control flag that stands for synchronize. If set to 1, then a sequence of numbers will be used to sort information packets. This also marks the beginning of a connection.

12. FIN - A 1-bit control flag that stands for finished. It also closes a connection, and indicates that there is no more data to be sent.

13. Window - A 16-bit field that is used for flow control. It indicates that a range of sequence numbers past the last acknowledged sequence number do not require further acknowledgment.

14. Checksum - A 16-bit field that checks segment integrity. A calculation is done on both the sending and receiving computer. This calculation is based on the segment’s information, so we can use it to check and see if the packet is indeed the same being received as it was sent.

15. Urgent Pointer - A 16-bit field that indicates the beginning of urgent information. Specifically, it points to a sequence number.

16. Options - A field that may be used to set various optional settings.

17. Padding - A spacer used to offset the Options field. Since every row must equal 32 bits, the Padding field must add to the Options field to equal 32 bits. Since the Options field may vary, variable Padding is needed.

18. Data - The actual data being sent to the recipient computer.


The Anatomy of a UDP Datagram

Don’t worry- UDP is a lot simpler as compared to the TCP counterpart. This is due to the lack of error checking UDP contains. Although UDP is famously known for not having error checking, there are slight UDP functionalities that can act as basic error checking procedures.

It’s important to know that the UDP error checking functionalities are quite basic. For instance, the UDP protocol contains functionality for a checksum so that we may check the integrity of data. This field can be turned off, however, so that a faster connection can be had. Also important to note is that UDP uses a fake header (known as a pseudo-header) that contains a destination address, so that we can determine whether or not the packets were sent to the right place. If they are indeed sent to the wrong place, a simple ICMP message may notify the source machine that the source is unreachable.

Keep in mind that even if errors are found within a UDP connection, data will not be retransmitted. So how much different is a UDP datagram from a TCP segment?

UDP Datagrams Explained

1. Source Port - An optional 16-bit field that specifies which port the datagram originated from.


2. Destination Port - A 16-bit field that specifies which port the datagram should be directed to on the receiving computer.

3. Length - A 16-bit field that specifies how long the UDP datagram is. This includes the UDP header and the data being sent. (The value is always at least 8, since the UDP header is eight octets.)

4. Checksum - A 16-bit field that operates much like the TCP counterpart. It is considered optional, however.

5. Data - The actual data being sent to the recipient computer.

You will notice that the datagram anatomy is much simpler- and that no source or destination information is included. So how does the data know where to go? As we briefly reviewed earlier, UDP uses what is known as a pseudo-header. This header will act as a guide for the datagram, and can determine whether the datagram was delivered to the right address or not.


How To Configure A Router With Packet Tracer?

Computer networking professionals getting started with Packet Tracer may find the interface to be flustered. Being a development program, this is only natural. However, learning how to configure a router with Packet Tracer will put professionals on the right track to mastering the program in about half an hour.

By this time, you should already have the Packet Tracer download and have it installed on your computer. Open the program and select the router from the lower left-hand corner, and drag it into the center of the sandbox screen as seen below.



We will be setting up a very basic network that allows two computers to communicate, so the next step is to select end devices from the bottom left-hand corner and drag it to the sandbox screen. Do this twice to make two computers appear below the router.
Now select connections from the same bottom left-hand corner. When you connect like-devices(Such as a router and computer)  you use a crossover cable, so you should selectcopper cross-over cable from the second menu to the immediate right. Click on Router0, and connect the cable via FastEthernet0/0 as seen below:


Now click the PC0 and select FastEthernet. You will notice that although a link is established, it is not functional. You can tell by the red dots that are present on both ends of the connection. Once the router is configured correctly, the red dots will turn green to indicate the devices are able to communicate.
Do the same operation to PC1, only this time connect the cable to FastEthernet0/1 sinceFastEthernet0/0 is already taken by PC0. Your network should be similar to the one below at this point:

Configuring The Router In Packet Tracer

A router that is turned off doesn’t work very well! Click on your router to bring up the configuration menu and verify that it is turned on.When on, there will be a small green light below the switch as seen in the diagram.

Next we have to open the Ethernet ports to allow communication. Although they are physically connected, they are in a state that is known as being in administrative shut down. Now click on the CLI tab to access the configuration menu. If you’ve used the Cisco IOS before, you will notice it looks and acts the same way.
 --------------------------------------------------------------------------------------------------------------

1. Press RETURN to start the session

2. Type enable to get to privileged mode (this gives you more options in configuring the router)

3. Type config terminal (or config t for short) to access the configuration menu.

4. Type interface fastethernet0/0 to access Ethernet0/0

5. Type ip address 192.168.10.1 255.255.255.0 to assign an IP address and subnet mask to the interface. 

6. Type no shutdown to open the interface up for business.
---------------------------------------------------------------------------------------------------------------
That’s it! You should now see a message similar to the following:

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up


Now we have to do the same thing for fastethernet0/1. If you don’t, there still won’t be a connection to PC1! Make sure to enter the IP address carefully as seen below:
---------------------------------------------------------------------------------------------------------------
1. Press Ctrl + Z to go back to the previous mode.

2. Type interface fastethernet0/1 

3. Type ip address 192.168.20.1 255.255.255.0 

4. Type no shutdown
---------------------------------------------------------------------------------------------------------------
At this point our router is configured properly. If you test out a ping, you will notice that the computers still don’t communicate, however!


Configuring The Gateway In Packet Tracer

Our last step is to configure the gateway on each desktop computer. The gateway is the address we assigned to the Ethernet port that the desktop is connected to. It will allow the computer to interface with another network, so our ping won’t work without it!

Click on PC0 to bring up the configuration menu. Under global settings you will find a field for the gateway. Enter the corresponding IP address of the router’s interface, which is192.168.10.1. Then click the FastEthernet tab on the left column to set the actual computer’s IP address to be on the network. Use 192.168.10.2 for the IP address, and 255.255.255.0 for the subnet mask.


Do the same thing for PC1, only use 192.168.20.1 for the gateway address, 192.168.20.2 for the IP address, and 255.255.255.0 for the subnet mask. You can confirm that your network works by sending out a packet of information from PC0 to PC1, and vice versa. Click the packet icon on the right menu as seen below:


Click on PC0 and then click PC1. On the lower right of the screen you will see a message box that says “Successful.” If it doesn’t, you may have had a syntax error when putting in an IP address or router configuration command. Review your work or ask for help among the community if you are stuck.

Congratulations! You have a small working network. A real-world application of this very network would be to have two computers connected to the Internet, whereas the router would then be connected to your telecommunications company. (Or what we would call the “cloud”).

How to Shine at an Interview

How to Shine at an Interview

Interviews, interviews and interviews…they are the launch of a new job or a career. But most of the times, they are neither uncomplicated nor very pleasing. A job interview is the perfect example when a person faces excitement and pressure at the same time. This strange combination of sentiments can cloud our judgment and tie our tongues.
Perfection is not a man’s trait and many recruitment managers often over look puny interview mistakes. It is, however, important to be prepared to the greatest extent. There are some slip-ups that you can’t afford and there are some ridiculous mistakes that can cast a bad shadow over your abilities and future career.
On the day of your interview, remember to look good and confident and say all the right things. The rest will be fine. Don’t fret and try to think a little before uttering each word.
How to Avoid a Disastrous Interview
Don’t be late:
Make proper arrangements beforehand to ensure that you reach the designated place on time. Getting up earlier than usual for a single day won’t hurt! Don’t leave your dress un-ironed till the eleventh hour; you never know about electricity!
If something unexpected happens and you can’t avoid being late, whether it be a traffic jam or your alarm clock didn’t beat on time, immediately call ahead and inform them that you will be late. Don’t keep them waiting, they might adjust you at some other time or reschedule the meeting for some other day.
Don’t forget your CV and other important material:
Perfectly dressed to please and accompanied with your work bag, you accidentally left the file containing your impressive resumes, well crafted work samples and portfolios in the kitchen. That is bad but can be managed. You must have the CV and portfolios in your email. Try to get them printed before hitting the office for interview.
Handling a Wardrobe Malfunction:
Nearly everyone has faced some wardrobe malfunctioning before important events and moments. Such circumstances are sometimes beyond our control. One might get splashed by a passing by car on the way to the interview. It is quite possible that your crisp shirt ends up looking idiotic as you reach the office. The best thing to do in such circumstances would be to continue with the interview and at the start of it, explain what happened. Your interviewer would rather like you for your sound experience than loathe to your mud speckled shirt.
Be Prepared and Deliberate:
Do necessary research about the company and the people you are about to encounter. Any misinformation regarding them might suggest careless attitude on your part. You just can’t forget the interviewer’s name but if it skips your mind out of sheer nervousness, try to be smart and look at the nameplate on the desk for a clue or search for certificates or credits that might be adorning the walls. In this way you might get through the situation.
If You are a Young Professional…
If you are a fresh graduate, you are not a seasoned professional with decades of experience on the resume and employers are well aware of this fact. They know that your lack of experience will be compensated by the knowledge you have about the current trends and technology. Be confident about who you are. During the interview, you should emphasize on the fact that how enthusiastic you are about learning from the industry leaders on board.
Things Not to Say During an Interview:
When Asked to Introduce Yourself…
This is one of the trickiest yet interesting questions asked during the interview.
Upon this question, you do not need to ruminate on your life. The interviewer is least interested in your life’s intricate particulars. Don’t blurt out the following details.
  • A brief synopsis about your childhood.
  • How badly you want this job.
  • The details of your unstable marital life.
  • Your religious and political beliefs.
The potential employer certainly is interested in your professional capabilities and not in your personal life. All he wants to make sure is that you can diligently handle the task at hand.
I Hated My Last Boss:
Your last boss was a living misery and the sole purpose of his life was to make the lives of his subordinates miserable. You know this but you potential employers don’t know! Trash talking is a highly frowned upon habit. People do not like back biters in their team. Even if you are rightly speaking, you would not be liked for cursing your boss.
I Don’t Know Anything About the Company:
This is part of the homework that you should be accompanied with while going to an interview. If the interviewer asks why you are interested in this job and you come up with this sort of reply, then it could be easily assumed that all you are after is money and not a career. With today’s swift technology, there is no excuse for this kind of reply except slackness and irresponsible attitude. Google the company’s profile and grab all the important information so that you can justify the reason for your application.
Don’t Talk About Promptness…
Punctuality is a sought after trait. You show up 10 minutes late; most probably it is going to be fine. It is not going to be nice if you suggest afterwards that promptness is your strength. Avoid any such contradictory statements.
Yes, Yes, Yes, No, No!
One word answers are never persuasive. At an interview, it is your task to convince the interviewer that you are the perfect person for the post and you can do a fine job. Even if the question is vague, try hard to answer it in the best possible way. Don’t drone on and on, but avail every chance to prove that you are the person they are hunting for.
Don’t Embellish Your Experience
Don’t go too far on the road of convincing. Be truthful and honest. If you don’t know something the interviewer asks for, fess up and tell him how much you are looking forward to learn the new things. If you brag about qualities you don’t have, chances are that sooner or later the employer will find out. This situation will lead to even worse circumstances; you will certainly not be liked and you might get kicked out!
I’m Going to Need to Take These Days Off:
We all are committed to our personal lives and we all need to fulfill our responsibilities. The potential employer is clearly aware of this fact. Don’t bring up your personal life during the first interview. If you make it to the offer stage, talk about your personal issues and hopes. Talking about your life prior to a job offer will make an impression that either you are self obsessed or too confident that you will get the job.
And Another Thing I Hate…
Don’t scorn in front of a potential employer. Most people want to hear it all sweet and cutesy. Do not present opposing views on subjects that do not matter. It seeds ill feelings and you might get a rejection in the mind of the interviewer. If you don’t agree upon certain things, either say it politely and respectfully or just let it go. After all you want to score this job and have a good working relationship with your boss.
Most Common Interview Blunders:
According to a survey, the following are the errors job seekers make most often:
  • Using cell phone: 77 percent
  • Appearing disinterested: 75 percent
  • Dressing improperly: 72 percent
  • Appearing haughty: 72 percent
  • Talking disapprovingly about current or previous employers: 67 percent
  • Chewing gum: 63 percent
During a job interview, the interviewer seems vicious. Believe me, he does not want to humiliate or mortify you. He just wants to make sure that he does his job flawlessly by choosing the right person for the company. He is certainly not a sadist; his job (recruitment) makes him appear so!

10 Common Wi-Fi Problem and Fast Fixes to Overcome Them


10 Common Wi-Fi Problem and Fast Fixes to Overcome Them

Wireless technology just changed everything from crappy wires to easy portable network, but still every good thing brings something painful right with it so people face many Wi-Fi problems and we are just going to discus the most common 10 problem people usually face with their Wi-Fi. Well we have some easy solutions that might solve your problem.

#1. I cannot connect to my router, How do I resolve this ?

This is the major problem with many causes and can hit any kind of router no matter it’s the expensive one or just a normal one.
  1. If this problem occurs to you make sure that your router is configured to Dynamic Host Configuration Protocol (DHCP). If its is just try to disable and re-enable it.
  2. The second thing you can try is disabling the WEP security, because this security can interfere and drop your IP address.
  3. The last thing you can check for are the electrical interference something like microwave, alarm clock or any other thing that be interfering with your Wi-Fi router so disabling those devices may help you out.
If you are still not able to get your laptop connected to the router than you can simply reboot your router and computer and than restart again to see if now its working.

#2. What steps should I take to secure my Wi-Fi network ?

This is the normal question that arises in everyone’s mind when they first purchase a new router and get a new broadband connection fit in their house. They just want no outside intruder can access their connection except them so normally there are some steps you can take officially to protect your Wi-Fi Network.
  1. Wi-Fi Router normally comes with a WEP and WPA security encryption in which WPA is the best as it allows you to add numbers and words for premium security. Now to enable this security go to router administrator page by accessing 192.168.0.1 or 192.168.1.1, now under Wireless Security click on enable WPA and add your key and than press save and your router will reboot.
  2. The second thing you can do is Disabling the SSID (Service Set Identifier) broadcasting, so that hackers are not able to see my Wi-Fi network and this will some relief.
  3. The third can be done is too enable the router’s hardware firewall, that will block any suspicious connection.
  4. The last thing you can do is to disable the file sharing option for optimum security.

#3. How do I open ports on my router ?

Many functions and applications like personal web server, online gaming, IP Webcams, FTP Servers require you to open ports on your router to allow outside request to be sent to an internal computer on a home network. Well this procedure is called port forwarding and is pretty simple and can be done on any router with slight change in steps.
Open your router’s administrative page and find the label called Port Forwarding. Now just enter the service name and type your start port and end port numbers. If you are opening only one port than enter same numbers in both fields. Now select TCP as the protocol and click on OK. You can even check your routers website for more detailed instructions.

#4. How to I extend range of my wireless signal ?

Well this is just a long matter of discussion and many ideas can go wrong but still people try to experiment and come up with some innovative concepts on getting your signal pumped up, well we posted about 10 steps to improve your wireless signal you can check that and I addition to that you check out Boosting Wi-Fi signal using Beer Can.

#5. How to automatically connect to a Wi-Fi network ?

Sometimes you just want to connect to any network available in your area or maybe somewhere outside, it can be like that Wi-Fi connection does not have any security enabled and its is allowing you to connect but you just want that when ever you are in that range you are connected automatically than follow below steps.
  1. Go to Control Panel > Network Connections, now right click on your wireless network.
  2. Now click Properties > Wireless Networks > Advanced.
  3. Now check out if Radio button next to any preferred network is on just change it too any NON-Preferred network.
  4. Now you will automatically connect to any network in your wireless range.

#6. Which wireless channel should I use ?

Wireless 802.11b and 802.11g routers have at-least 11 channels and some routers come with 6 channel as default. Now if you are experiencing any problems or interference with your neighbor's router. So you can change your wireless channel to avoid any interference, well you can change your channel by going to routers administrator page and than under wireless settings option choose channels and switch to anything else from 1 - 11.

#7. How do I share files on a wireless network ?

You can share files between your computers over a wireless network easily by just configuring it to one workgroup. Now enable file sharing in Windows. Now just right click on the folder you want to share and choose sharing and security from the right context menu and click on sharing tab. Now put check in the folder labeled "Share this folder on a network" and "Allow network users to change my files" to enable other to modify your documents.

#8. Should I allow other people to access my Wi-Fi Service ?

Wi-Fi sharing does not have any potential harm but still some dirty minds can crack out your back, so its recommended that you should not share your internet connection with any stranger or outside intruder.
