Unit 2 P3

For my P3 I am going to explain the purpose of different software utilities and also I will include screen shots or images to cover security virus protection and/or firewalls, clean up tools for removal and cookies and/or internet history and/or fragmentation and drive formating.

Security software utilities contain virus protection and firewalls.Virus protection scans and prevents computer system from getting a virus, worms and trojans that might infect the system. Viruses make the job easier for hackers as the software protection is much lower, this might cause that hackers will take over the system or steal any data or personal detail. Anti virus is very important as it protects the software and scans regularly to check any viruses. Virus protection require regular update to make sure the viruses are stopped as new viruses are being created constantly by hackers. Firewall is a software utility that monitors the traffic on a computer system connected to a network. Before going on to certain page on internet, firewalls job is to check if the source is trusted and also blocks the traffic from unwanted source, this prevents the system from getting any virus or trojans installed.

Clean up tools are used to make sure that useless/unwanted files are deleted, the system is working properly and to make sure hard drive is organised to optimal performances. Most of the operating systems usually have built in clean up tool such as Windows Disk Cleanup or Omnidisksweeper. Clean up tools remove cookies which are downloaded when accessing websites and can also improve system performance. Clearing internet history and free up disk space are also ways to improve your system performance.

Drive formatting is used to completely wipe the data from a system. When company is selling a computer/ laptop to a customer, they would need to upload the files needed and install operating system. There are different levels of drive formatting, as mentioned before one level of drive formatting is to wipe the whole computer. Another level might be just to wipe one hard drive than all of them. Before formatting, it is best to move all the files like videos, images, games etc. on one hard drive, to be able to wipe the rest of computer.
