Answer to Question #256116 in Computer Networks for khanyi

Question

Discuss the essential properties of the following types of operating systems:

a. Batch;

b. Interactive;

c. Time sharing;

d. Real time;

e. Distributed.

Answer 1

a. Batch; Jobs with similar needs are batched together and run through the computer as a group by an operator or automatic job sequences. Batch is cutting large jobs that need little interaction.

b. Interactive; This system is composed of many short transactions where the results of the next transaction may be unpredictable. Response time needs to be short since the user submits and waits for the results.

c. Time sharing; This system uses CPU switches rapidly from one user to another. Instead of having a job defined by spooled card images, each program reads its next control card from the terminal, and output is normally printed immediately to the screen.

d. Real time; Often used in dedicated application. This system reads information from sensors and must respond within a fixed amount of time to ensure correct performance.

e. Distributed; This system distributes computation among several physical processors. The processors do not share memory or a clock. Instead, each processor has its own local memory. They communicate with each other through various communication lines such as local area network.
