Question 5:

Maintenances of desktop computer schedule

Tasks	Time	Schedule
Task 1	10 minutes	Clean or remove the unnecessary and unwanted files, defragmentation tools and monitoring the CPU temperature
Task 2	20 minutes	Visiting the approved sites and avoiding the unwanted sites, disk space analysis
Task 3	30 minutes	Installing the virus protection application software
Task 4	5-10 minutes	Checking the applications and if any error is encountered in between working it is essential to consult with the technician.

 

Question 6:
