Evaluation of Microprocessor Evaluation of Microprocessor The first microprocessor introduced in 1971 was a 4-bit microprocessor with 4m5KB memory and had a set of 45 instructions. In the past 5 decades microprocessor speed has doubled every two years, as predicted by Gordon Moore, Intel co-founder. Current microprocessors can access 64 GB memory. Depending on width […]

The different Abbreviations in Computer Science
The different Abbreviations in Computer Science Abbreviations In this chapter, we will discuss the different abbreviations in Computer Science. The following table lists down those abbreviations − Abbreviation Full-name A/D Analog-to-Digital ABC Atanasoff Berry Computer ACM Association for Computing Machinery AI Artificial Intelligence ALGOL Algorithic Language ALU Arithmetic Logic Unit AMD Advanced Micro Devices APRANET […]
Domain Specific Tools
Depending on its usage, software may be generic or specific. Generic software is a software that can perform multiple tasks in different scenarios without being modified. For example, a word processor software can be used by anyone to create different types of documents like report, whitepaper, training material, etc. Specific software is a software for a particular application, like railway reservation system, […]
Computer – Overview
Today’s world is an information-rich world and it has become a necessity for everyone to know about computers. A computer is an electronic data processing device, which accepts and stores data input, processes the data input, and generates the output in a required format. (toc) The purpose of this tutorial is to introduce you to […]
All modern computers and computing devices
All modern computers and computing devices Historically computers were classified according to processor types because development in processor and processing speeds were the developmental benchmarks. Earliest computers used vacuum tubes for processing, were huge and broke down frequently. However, as vacuum tubes were replaced by transistors and then chips, their size decreased and processing speeds […]
Secondary Memory
You know that processor memory, also known as primary memory, is expensive as well as limited. The faster primary memory are also volatile. If we need to store large amount of data or programs permanently, we need a cheaper and permanent memory. Such memory is called secondary memory. Here we will discuss secondary memory devices that […]
Computer’s Input/Output Ports
A connection point that acts as interface between the computer and external devices like mouse, printer, modem, etc. is called port. Ports are of two types (toc) Internal port − It connects the motherboard to internal devices like hard disk drive, CD drive, internal modem, etc. External port − It connects the motherboard to external devices like modem, […]
Role of Computer in Today’s World
In today’s world, for almost every activity whether personal (for example, operating personal savings bank account) or business-related (for example, selling any product or services); in some or the other way, we rely on the computer system. (toc) Due to the growing dependency on computers, every small and big organizations and other business companies have […]
Computer System
A computer system is an integrated form of different components that work together to give a desirable result. It has different component and each works for a specific purpose; however, they generate a common result as required by the user. (toc) Computer System Components of Computer System Let us now understand the following basic components […]
Computer Programming Languages
The computer system is simply a machine and hence it cannot perform any work; therefore, in order to make it functional different languages are developed, which are known as programming languages or simply computer languages. (toc) Over the last two decades, dozens of computer languages have been developed. Each of these languages comes with its […]
