How do u block a website on your PC ??

I use Facebook on my office PC, but i have a habit to remain Logged in, even why i shutdown my PC.So in my absence if anyone has turned ON my pc & accessed Facebook, then that would be a problem for me.

So what i can do is, I can block certain websites, so that nobody can access it. Here is an easy way of doing so. blocking a site.

 

Go to

C:\Windows\System32\drivers\etc

you will see a file named HOSTS.

Open it with NOTEPAD.

Then search for the line 127.0.0.1 localhost

To block the website facebook.com for example, add this text under 127.0.0.1 localhost:

127.0.0.1 www.facebook.com

You can add as many sites as you want, but do not forget to prefix it with "127.0.0.1".

6. Save the file

Now Facebook will get blocked in all web browsers

Tips to enhance the system speed

1.Let your PC boot up completely before opening any applications.

2.Refresh the desktop after closing any application. This will remove any unused files from the RAM.

3.Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).

 

4.Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM

5.Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.

6.Delete the temporary internet files regularly.

7.Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.

8.Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.

 

9.When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.

10. Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum.

RAM IS THE WORKING AREA (DESKTOP) OF THE CPU, KEEP IT AS EMPTY AND UNCLUTTERED AS POSSIBLE!

Port in computing

 

1. An Internet port is a number that tells what kind of protocol a server on the Internet is using. For example, Web servers typically are listed on port 80. Web browsers use  port when accessing web pages by default, but you can also specify what port you would like to use in the URL like this: http://www.excite.com:80.

 2. A hardware port are the ports which are at the back side of the CPU where a keyboard, a mouse , speakers can be plugged.

 

3. The verb port is used for editing of a software program's code so that it can run on another platform.
