Explain the effect of activities.
Firewall
Fire wall Will check inbound and outbound traffic on your computer, and block not necessaries data which is come in to computer. firewall will makes computer more secure than computer which does not have.
Anti-virus update
Even though firewall can reduce computer secure risk , but there are hacks and virus can make fire wall stop working properly. that is why we need to update latest Anti-virus database.
Schedule scan
As we know anti-virus can not schedule scan before we setting. (there are some anti-virus software will automatic set it after we install it.) anti-virus schedule scan will check computer regularly, if there are any computer risk, we can find it before it cause a big problem.
Update operating system
No any software is safe in this world including operating system , update operating sytem will help you repair system security risk and any bugs, it sometimes also bring the new feature of system.
De-fragment
De-fragment hard drive it is like cleaning house for you computer, it pick random data and put them together, delete not useful data and re-arrange space for new data. in the other word it makes computer "faster".
Drive formatting
Drive formatting use for cleaning out space in drive. it can also cleaning virus as well.
There are two ways of formatting, one is quick formatting, it can formatting the drive quickly. but if computer has virus inside, it will be remain inside.
The other one is formatting , formatting will thoroughly cleaning the computer. but it takes more time than quick formatting.
Create folders ;copy files; paste files and delete files will help to manage files more convenient.
Back-up
In case if you computer broke down lost all files, we need to have back up of our system and data.

In case if you computer broke down lost all files, we need to have back up of our system and data.
Task 1 C
System profile
A system profile is a uitility that provide the detail of information program/software which has installed in this computer.Computer system backup utilities can back up data stored on a disk which if you computer corrupted it will be very helpful.
File managerFile managers provide a convenient method of performing routine data management tasks, such as deleting, renaming, cataloging, uncataloging, moving, copying, merging, generating and modifying data sets.
Disk error-check can scan the disk to find the files or areas where is corruped or not install correctly and deleted them . it helps solve disk problem more easily.
Printer installation.
The video shows above it explained to install the printer and download printer drive.
As we now, when we bought a printer, when you plug USB to computer, sometimes it does not work, it is because, this computer does not have driver to support printer running, therefore why we need to know how to install printer drive.
In the other hand, sometimes computer default driver can support some printer running, but the disadvantage is it will not giving full function of printer.
Undertaken clean up of the equipment.
In this video , it shows three equipment what we use to cleaning the computer ,
Brush, foam-clene and phone-cleane hygiene wipes.
(In this video because Phone-clene hygiene is last for long time so it already dry out , therefore why we using foam-clene spray on it.)
computer is a delicate device, it can be damage form virus;hacker which is virtual. and it can also be damage by dust,water, etc.. physically , therefore why we need to learn how to cleaning our computer for long term use.
DVDR/W installation.
These two video in different way shows how to install DVDR/W and how to check it if DVDR/W install properly.
As previous session, we were talk about using CD/DVD to back up our system, just in case if system is crashed down lost all data inside.
In order to do that we need to have DVDR/W first. DVDR/W is use for read and write data from disk, if we do not have DVDR/W we can not write data to the disk; and read data from the disk.
Installation of XP service pack 3
In this video shows how to install XP service pack 3 manually.
No any software is safe in this world including operating system , update operating system will help you repair system security risk and any bugs, it sometimes also bring the new feature of system. therefore why we need to update our system to XP service pack 3.
