peripheral devices.

- June 23, 2019

The microprocessor takes the data from the real world , processes as is according to a program and sends the result to the output devices so that the result can be presented in the real world. The communication between the microprocessor and the outside world (user) is established through I/O devices only. These devices are known as peripheral devices. example. keyboard, mouse, joystick, printers etc. Definition of peripheral devices : - The peripheral device is a computer device such as: - keyboard or scanner. These devices are not part of the computer. These are auxiliary devices of the computer. A peripheral device provides input / output (I / O) functions to a computer and does not have the capability of computing. Despite the lack of computing capability, it also acts as a computer accessory. The peripheral devices connect to the computer through several I / O interfaces, such as communications , universal serial bus (USB) and serial ports. Type...

Deadlock in os

- December 30, 2019

DEADLOCK what is deadlock ? Deadlock is a situation in which two computer processes share only one resource, due to which no process can access the resource. That is, a deadlock is a condition in which two or more processes fight for only one resource, due to which no one is able to access the resource. For example, suppose there are two friends and both want to play computer games, due to which both fight. One has a remote control and the other has a cd of games. Due to which neither of the two friends are able to play but neither of them is ready to cooperate. This condition is called deadlock . According to the picture we have two processes A and B and two resources r1 and r2. It contains resource r1 that is allocated with process A, and resource r2 that is allocated with process B. But resource r2 is required to complete the process so it requests r2, but r2 is already allocated with B. Similarly process B requires r1 to complete its execu...

OPERATING SYATEM||HOW USER CAN INTERACT WITH THE COMPUTER HARDWARE

- June 23, 2019

The Operating system is an interface that provides interaction to user with computer hardware like hard disk, RAM , printers , keyboard etc. it's a most important program in a computer system. diagrammatic representation of user interface with computer hardware this is the one program that runs all the time ,as long as computer is operational .The fundamental goal of computer system to execute user programs and to make solving user problem easier. the primary goal of an operating system is to make computer operation easy. The secondary goal of an operating system is to make efficient operation of the computer system . What is an Operating system ? The Operating System acts as a medium between th...

OSI MODEL in computer network

- December 31, 2019

OSI MODEL What is the OSI model ? The full name of the OSI model is Open Systems Interconnection, developed in 1978 by ISO (Internationa l Standard Organization ) and the model consists of 7 layers. The OSI model is a reference model for communication between two users in a network. Each layer of this model does not depend on the other layer but there is a transmission of data from one layer to another. The OSI model describes how to send and receive data or information in a network. All layers of the OSI model have their own different functions so that data can be easily accessed from one system to another. The OSI model also describes how network hardware and software function as layers with each other. Layers of OSI MODEL OSI model has the following 7 layers layers in OSI model PHYSICAL LAYER ...
