Abstraction: Spooling overlaps I/O of one job with computation of another job, at the cost of some disk space and some tables that the operating system needs to manage. Spooling - overlap the I/O of one job with the computation of another job.

a PASCALprogram or a Fortran program etc. The control card told what the job was supposed to do, e.g.
To speed up processing, the operator grouped all the jobs withsimilar needs called a batch together and run them together. The operating system was always memory resident. Its major task was to transfer the control automatically from one job to thenext. Simple Batch Systems - Second Generation.In the second generations of computers, the operating system was simple.

Applications programs - define the ways in which the system resources are used to solve the computing problems of the users (compilers, database systems, video games, business pro grams).Operating system - controls and coordinates the use of the hardware among the various application programs for the various users.Hardware - provides basic computing resources (CPU, memory, I/O devices).Use the computer hardware in an efficient manner.Make the computer system convenient to use.Execute user programs and make solving user problems easier.
printing, standard libraries, windowing systems, etc.) Operating system goals: Standard Services Provider: It provides standard facilities that everybody needs (e.g.As Coordinator: It allows many users/applications to work together in a fair and efficient ways (e.g.

It is essentially a software engineering problem - how do you convert what hardware provides into what an application programmer wants.An operating system implements a virtual machine that ishopefully easier to program than the raw hardware.A program which provides an illusion of infinite resources (CPU, memory, I/O devices,networks)to an user (i.e.Its the most fundamental system program - one which controls all the computer's resources and provides a base upon which application programs can be written.A program that acts as an intermediary between a user of a computer and the computer hardware.Introduction CSC 325 Operating Systems with an Emphasis on UNIX Chapter 1 Introduction
