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 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 […]
Microprocessor Concepts
Microprocessor is the brain of computer, which does all the work. It is a computer processor that incorporates all the functions of CPU (Central Processing Unit) on a single IC (Integrated Circuit) or at the most a few ICs. Microprocessors were first introduced in early 1970s. 4004 was the first general purpose microprocessor used by Intel […]
Primary Memory
Memory is required in computers to store data and instructions. Memory is physically organized as a large number of cells that are capable of storing one bit each. Logically they are organized as groups of bits called words that are assigned an address. Data and instructions are accessed through these memory address. The speed with which these memory […]
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 […]
Fundamental Concept
A computer is basically a programmable machine capable to perform arithmetic and logical operations automatically and sequentially. It is also known as a data processor, as it can store, process, and retrieve data as per the wish of the user. (toc) Computer Data processing involves the following three activities − Input of data Manipulation/processing of […]
