Operating System In this post, we will discuss general properties, types of application advantages, disadvantages and basic requirements of different types of operating systems. Batch Operating System Batch processing requires the grouping of similar jobs, which consist of programs, data, and system commands. The advantage of this type of programming...
Evolution Of Operating System An operating system may process its task serially or concurrently. It means that the resources of the computer system may be dedicated to a single program until its completion or they may be allocated among several programs in different stages of execution. Due to different processing...
Introduction In Computer Science, the term software means a set of instructions in the form of a program to control the processing of a computer. These programs are used for various purposes in the computer system. A series of instructions that performs a particular task is called a “program“. The...
Introduction Input-Output devices are very important component of computer system. Here we will discuss about Input-Output devices of computer system. First, we will discuss briefly about Input-Output devices and then move on to the function and structure of some Input and Output devices and we will discuss about the newer...
Optical Memory Optical memories or Optical disks are alternate mass storage devices with huge capacity [up to 20 GB]. Higher density is achieved through tightly focused lasers which can access a very small storage area. Information is written to or read from an optical disk using a laser beam. Only...
Semiconductor [Main] Memory All computers except very small computers contain both semiconductors as well as magnetic memory. All modern computers use semiconductor memory as its main memory [Primary Memory]. Semiconductor memory is known as Random Access Memory [RAM] because any part of the memory can be accessed for reading and...
