Network Topology

Types of Network Connections Computer networks can be broken down historically into topology , which is a technique of connecting computers. The most common topology today is a collapsed ring. This is due to the success of a network protocol called the Ethernet. This protocol, or network language, supports the Internet, Local Area Networks, and Wide Area Networks. Star Topology A star topology is a design of a network where a central node extends a cable to each computer on the network. On a star network, computers are connected independently to the center of the network. If a cable is broken, the other computers can operate without problems. A star topology requires a lot of cabling. Bus Topology A bus topology is another type of design where a single cable connects all computers and the information intended for the last node on the network must run through each connected computer. If a cable is broken, all computers connected down the line cannot r...

Operating System

Operating System: - An operating system is a system software which is used to operate a computer its work as an interface between user and machine it’s may enabled to computer hardware. In other word we can say that “ An operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs . ” An O perating System or OS is a software program that enables the computer hardware to communicate and operate with the computer software . Without a computer operating system, a computer and software programs would be useless Some popular Operating Systems include UNIX Linux, Windows,ANDROIDetc. Types of Operarting system:- Single user Single Tasking Single user Multitasking Multiuser Multitasking

Introduction to Computer

COMPUTER- Basically the term COMPUTER is derived from "GREEK" word which means to calculate. Hence we can say that computer is a calculating device. In other word we can say that Computer is an electronic device which store data processing and give out the result. A computer is an electronic device which performs "Arithmetical and logical operation. A computer understood binary digit that is 0 and 1. Computer is an electronic device which accepts data form user through input device and process the data with the help of processor after processing we desired output form. A computer also refereed as data processor because It can store the data, Process the data, and Retrieve data whenever desired.
