Clustered system is another form of multiprocessor system. This type of system contains multiple processors but the design differs from multiprocessor system. The clustered system consists of two or more individual systems or nodes that are joined (coupled) together. In clustered system, individual systems (or clustered computers) share the same storage and are linked together…
Computer architecture means construction/design of a computer. A computer system can be organized in a number of different ways. However, there are three princ.pal ways to connect components in a computer, which are as follows: i) Von Neumann architecture ii) Bus architecture iii) Single & Multiprocessor architectures Von Neumann Architecture John Von Neumann explained the…
The Instruction Execution Cycle, also known as the Fetch-Decode-Execute cycle, is the basic operational process of a computer system’s CPU (Central Processing Unit). It describes the steps the CPU takes to execute a single instruction from a program. Every single statement of a computer program is called machine instruction. It may consist of operation code,…
What is Operating system?Operating System is the most important software that runs on a computer and many other devices such as mobile devices. Therefore, that study of operating systems is fundamental to the students of computer sciences. In this will serve as a prerequisite for the understanding of actual topics of operating systems. which are…
