Types Of operating system

Question 1

Operating system(OS)

Answer 1

The operating system is what coordinates all the operations of your computer.
It manages all the resources on the computer, such as the CPU and RAM, and controls the software and hardware.

Question 2

Real-time operating systems

Answer 2

Inputs are processed and responded too instantaneously.
Why choose real-time?
* It provides a fast response.
* It is best used where inputs such as traffic lights and air traffic
control systems must be processed and responded too immediately.

Question 3

Single user/single task operating system

Answer 3

One user can use the system at a
time and one application can run
at a time.
Why choose the single-user single
task?
* It requires fewer resources.
* It is best used on devices that
have limited processing and
memory, which could not handle
running multiple applications, for
example basic mobile phones or
a simple handheld game (such as
a Virtual Pet).

Question 4

Single-user multitasking operating
systems

Answer 4

One user can use the system at a time, but many
applications can run simultaneously.
Why choose single-user multitasking?
* It allows the user to use several applications at
once.
* It is best used on systems where a user
needs to be able to switch quickly between
applications, for example, an office worker using
a laptop or desktop PC.

Question 5

Factors affecting the performance of Operating system

Answer 5

Hardware factors
1. Limited RAM capacity
2. Limited CPU speed
3. Number of cores
4. Slow hard-disk
Malware factors
1. Viruses
2. Spyware
3. Warms.
Virtual memory factors
1. Not enough HDD space
2. the RAM is not fast enough
