Answer:
Updating OS, defragmentation of memory and hardware maintenance.
Step-by-step explanation:
There are two main components of the computer system, they are software and hardware components. The software is the operating system and the application software and utilities. To optimise the OS, it should be updated, at least every month.
The hardware is of four parts, namely, the input, output, memory and processor unit. These parts should be serviced monthly and defragmentation of the memory should be monthly for optimisation.
