The effect and benefit on your computer system when you under take activities

There are many activities are undertaken to make the computer system better, faster and too cause less problems. Virus protection is used to stop viruses from destroying your documents; virus software will block all viruses. Viruses don’t need permission from users to destroy the files. The virus can go from one computer to another. By updating the virus definition files your computer becomes safe and virus free. The advantages of updating your definition files are that:
· Fully automated. It is only necessary to update one server to update all machines in the network.
· Minimal configuration required.
· Only the portion of the file that contains new data is retrieved by the computer. In previous versions, this was a feature that only Live Update had.

Scheduling your full system scan is a good thing because then you won’t forget to scan your computer for viruses. You can schedule the time when it’s right for you and when you’re not using the computer. The full system scan will be happening in the background. It will take time to scan your computer but it all depends on the number of files you have on your computer. The advantage of scheduling you’re your computer for a full system scan is that you will never forget to scan your computer and you will get a scan done every week when it’s scheduled for a scan.
Windows XP Service Pack 2 (SP2) is a fast, free way to improve protection of your organization’s Windows XP–based computers. Service Pack 2 provides advanced security technologies and innovations from Microsoft and establishes a stronger security infrastructure that helps defend against viruses, hackers, and worms. Service Pack 2 also includes tools that enable manageability and control so that it is easier to be safe and improves overall productivity by helping users avoid time-wasting threats.

Defragmentation is the process of locating the noncontiguous fragments of data into which a computer file may be divided as it is stored on a hard disk, and rearranging the fragments and restoring them into fewer fragments or into the whole file. Defragmentation reduces data access time and allows storage to be used more efficiently. Some operating systems automatically defragment storage once in a while; others require that the user occasionally uses a utility for this purpose.The advantage of defragmenting the hard drive is that:
· it allows you to select files and directories
· if you defragment your hard drive regularly it will increase the overall performance of your system
· Instead of defragmenting the whole disk you can select profiles to defragment
· User-friendly interface doesn't require a specific knowledge (look at screenshots)
· Possibility to move files to the end of the disk (for rarely used files)
· Defragmentation scheduler allows to set date and time for every profile

The advantages for drive formatting are that it allows compressing files and therefore saving space on your drive. File system lets you to add allow and deny permissions on individual files and folders for specific Windows users, something you cannot do in the FAT file system. When you are formatting your drive there is a chance of you loosing all your files so don’t forget to back up all your files in a removable disk.

Firewall is needed to protect outsiders from using your network. They can be using your network without you knowing. Unauthorized people can get in to your computer and start controlling your computer and sending out spam using your computer. Firewall is a system that secures your network. Firewall can be installed via hardware or software. The advantage of you having a firewall installed into your computer is that unauthorized users can’t get into your network and start using it.

When you create folders for your files all your documents are all organised and easy to find. You should create different folders for different documents, having the files in different folders saves time searching for the file if your files are in the right folder then you will find the file quickly. It saves time. Your folder doesn’t need to be in my documents folder it could be anywhere. There any many advantages for creating folders:
· Makes things easier for having a folder for each subject
· Saves time
· Files will be organised

You copy and paste from one place to another so it is in the right location. You would do this so it’s easy to find and you won’t have to spend too much time in finding the file. You can copy the files from your area on the computer to a USB or other storage devices. The advantage of this will be that the files are in the right place and if you save it on a USB there will be a back up copy of the document.

The advantage of deleting files is that all the files that you don’t need anymore you can delete, if the file is private and confidential and you don’t need it anymore you can delete the file and then empty the recycle bin. This way no one will see or find the document you have deleted. Having documents on your computer that you won’t need anymore takes up space on your computer. Having too many programs and files on your computer makes your slow and when you’re trying to save your file and there isn’t any space you won’t be able to save your documents.
The advantage of back up to CD using compression software is that

Backup compression used during the backup process can often reduce the mount of space required by 50% or more. You can easily backup your files with zip compression as to a single file as to multiple files. By using compression, you can backup to CD more than 1 GB.
