What is an IP address?

An IP address or Internet Protocol is a 32-bit number address, which isassigned to each computer (technically called a host) connected to the Internet. It is the address to which different types of data are sent to your computer. It consists of 4 octets. Each octet equals 8 bits and has a range from 0 to 255. (Every IP address on the Internet is sectioned off into classes from class A to class E, depending on a different range of numbers). Well I always believed that sometimes pictures speak louder than words so here is an example of a typical IP address:


189.134.221.61

| | | |

| | | |---------> (4th octet. 8-bits. Ranges from 0 to 255)

| | |-------------> (3rd octet. 8-bits. Ranges from 0 to 255)

| |-----------------> (2nd octet. 8-bits. Ranges from 0 to 255)

|---------------------> (1st octet. 8-bits. Ranges from 0 to 255)

10 ways to tune up your PC





Everything needs a tune-up: cars, pianos—even your computer! Here are 10 ways for you to tune up your PC to help keep it running smoothly and efficiently.

What you'll need:

Windows-based PC


USB drive (1 GB minimum)


-----------------------------------------------------------------------
-----------------------------------------------------------------------




1. Keep your PC up to date


One of the best things you can do to protect your PC is also one of the easiest: Make sure you are set up to get automatic updates from Microsoft. If you use Windows and other Microsoft software, such as Microsoft Office or Windows Live Essentials, then you should use the Microsoft Update service. You'll also get notices about new Microsoftsoftware that you can download for free.

So how do you turn on automatic updates? Simple: Go to the Microsoft Update website. If you don't have automatic updates turned on, we'll help you through the process.

-----------------------------------------------------------------------



2. Performance
Next, you should “look under your PC's hood” to see how efficiently your computer is operating. To check your PC's performance in Windows 7, click the Start button , typePerformance in the search box, and then click Performance Information and Tools in the search results.

Your system's processor, memory, graphics handling, and your hard drive are rated according to their capabilities. If you need more information on what these ratings mean, click the What do these numbers mean? link found under your base score.

3. Action Center


In Windows 7, Action Center is a central area for messages and warnings about security that need your attention. When there is nothing to report you won't even realize it's there, but when something occurs that you should know about, you will see an Action Center flag notification on your taskbar.

When you click the warning you can choose to resolve the issue from there. You can also open Action Center itself to see other notifications and actions you can take to help keep your PC running smoothly.

Running Windows Vista? Learn how to use Windows Security Center.

4. ReadyBoost


If you have a USB drive with at least 1 GB to spare you may be able to make your system faster using ReadyBoost. ReadyBoost uses available storage space on a removable device to boost your system speed. Most flash drives and flash memory cards can help speed up your computer.

Running Windows Vista? Learn about using memory in your storage device to speed up your PC.

5. CPU utilization


Your Central Processing Unit (CPU) is the brains of your computer. It organizes the processes in your computer to help keep it running smoothly. If you're wondering if an application may be slowing down your system, you can check the Performance tab inWindows Task Manager to see if the online movie you are watching is taking more than its fair share of power.

Windows Task Manager provides details on each process running on your computer, allowing you to find those programs affecting your PC's efficiency.

6. Check for viruses and spyware


Has your computer really slowed down since you bought it? Are windows occasionally popping up or programs starting independently? Is your hard drive constantly spinning? These and other problems may be caused by viruses or spyware.

Be sure your computer has protection against viruses, spyware, and malware. DownloadMicrosoft Security Essentials (it's free) or see recommended consumer security software providers for Windows.

Running Windows 7? Check out the security checklist.

Running Windows Vista? Learn more about security and safety.

-----------------------------------------------------------------------



7. Clean up your hard drive


Just like your closet needs a good cleaning occasionally, your hard drive does, too. To unclutter your hard drive, use Disk Cleanup. When you use Disk Cleanup you will toss out those old unneeded temporary files, all the trash in your Recycle Bin, and many other bits and pieces that are no longer needed.

Run it on a regular basis and you will be amazed at your computer's efficiency.

-----------------------------------------------------------------------



8. If you don't use it, uninstall it


Even a brand-new computer has programs that you never use and don't need. If you don't use a program, uninstall it. This goes for pre-installed software, trial software you decided not to purchase, or software that you've replaced with an updated version.

Many unwanted programs run in the background upon startup whether you are using them or not. They take up disk space and memory. If you don't need the program, uninstall it. One warning: If you don't recognize a program name or know what it does, don't uninstall it until you've checked to see if it's software essential to running your PC.

9. Defragment your hard drive


Over time, files on your computer are moved around the hard drive. Eventually it takes your computer longer to find various parts of the programs which have been moved or fragmented. To boost your computer's speed and overall performance, defrag your hard drive on occasion. In Windows 7, Disk Defragmenter rearranges fragmented data, making your computer operate more efficiently.
