What are the good characteristics of operating system?

Answer 1

By Martin Mairu

Operating systems are a platform on which computer programs run to execute certain actions. They also manage computer hardware resources.

Good operating systems should be suitable for the hardware for which they were designed to operate. It should also be reliable and operational at all times so as to support the processing activities of the users effectively. They also have to support online processing operations including many network protocols, hardware and applications for using them. The allocation of the resources of a system depend on the operating system and thus, operating systems should coordinate and have good control of input and output operations and the devices on which they are performed. Operating systems should enhance access to any particular devices which is very necessary and also simplify the means by which all programs being processed undertake input and output operations. They should have a standard set of control instructions to handle the processing of input and output tasks.

Good operating systems should enhance time sharing so as to schedule tasks efficiently. Good operating systems should also manage computer system resources effectively. Operating systems should manage the use of devices in order to approve or deny the use of particular devices. Good operating systems must also ensure proper processing of computer tasks by controlling the order of their execution according their priority and special processing requirements. They should also be very secure
