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 […]

(toc) The Internet system carries an extensive range of information resources and services including World Wide Web (WWW), telephony, electronic mail, etc. It uses standard internet […]
Computer Networking Terminology
In this chapter, we will discuss the major terminologies used in computer networking (toc) WAN It stands for Wide Area Network and covers a wide area such as a city. LAN It stands for Local Area Network and covers a small area such as a small office or home. It physically connects all the computers […]
Data Processing
Collection, manipulation, and processing collected data for the required use is known as data processing. It is a technique normally performed by a computer; the process includes retrieving, transforming, or classification of information. (toc) However, the processing of data largely depends on the following − The volume of data that need to be processed The […]
Computer Networking
A computer networking is a process of connecting two more than two computers with the purpose to share data, provide technical support, and to communicate (especially for the business purpose. (toc) Internet is the technology that is used to connect different computer systems (located in different geographic location). Networking technology has revolutionized the world and […]
