these may not be quite a use for u but it pays just to know it.....
Brainy bytes 1: batch operating system - time sharing operating system :
In the second generation of computer development....a method called batch operating system was used. tn these systems,users had to prepare the data and the programs on a paper and then had to submit it manually to a computer centere for processing or compiling....the computer centere collected these user jobs and fed them into the computer in a batch wise at regular intervals,this batch wise output was then returned back to respective owners with result.
this caused a time delay between batches and users found it difficult to locate errors in thier program......and if they found they had to wait alot for reprocessing. .. . so, and John kemeny and Thomas kurtz of dartmouth collage introduced concept of time sharing- -operating system which allows a large number of users to use the main computer .there are many terminals connected to the main computer to use as feed.each terminal is used by a user providing acces to the main computer.this type of system is used in such a way that time of the main computer is divided into many slices and allocated one-by-one.the processing speed of the cpu is such that each user gets the illusion that he is using the computer alone.this introduction of time sharing helpd in productivity of programmers and also made online systems feasible,resulting in new applications like air line reaservation systems etc.
