type of hardware components; input/output devices, processing and controlling and memory and storage devices. Input devices include mice, keyboard, cameras and microphones. Output devices may include a monitor, speakers, and printers and so on. Some devices are classified as input and output devices, such as a sound card or certain types of video cards. A sound card can process audio and output to a speaker, it can also be used to record audio through an audio input port. There are some types

Introduction:- Computer is an electronic device which can take input from the user and process this input data and if need, store data or information on storage devices and give output on output devices. It follow the instructions us it is which we input. It takes input through Keyboard, mouse, etc and then it processes the input data and give output on display screen and store data if need. Desktop Computer:- Mostly called personal computer (PC), design to fit completely on a typical desk

justified Myra's chosen strategy for competitive advantage and the business process that she would like to improve through the application of technology. In the Stage 2 assignment, you will identify the inputs, processing, and outputs of Myra's selected business process. Those inputs, processing, and outputs form the functional (business) requirements for an IT system to improve the process. The first step in identifying the functional or business requirements for an information system is to develop
