Cambridge Igcse Ict Chapter 2 And 3 Input Output Devices This document is a lecture on basic computer organization by talat ambreen from the international islamic university, islamabad. it discusses the basic operations, organization, and components of a computer system including input, output, storage, and processing units. The document discusses how computers represent and store data. computers use binary digits (bits) represented as electrical voltages to store all types of data. bits are grouped into bytes of 8 bits to represent characters, numbers, images, sound etc. memory is measured in bytes, kilobytes and megabytes.
Ict Lecture 1 Social Sciences Pdf Input Output Computer Data An input device is any hardware component that allows you the user to enter data or instruction into the computer. there are many manual automatic input devices. 2.1 objectives have discussed about the organization of computer. we have understood roles of various components of computer, their funct onal dependency on each other and roles of memory. in this unit, we will discuss in details about the input o tput organization and memory unit of the computer. the discussion in this unit is confi. Input – how computers accept information input allows users or devices to provide data. examples of input devices: keyboards, touchscreens, voice commands, and sensors (e.g., thermostats). input can come from users, sensors, or stored data. Input output (i o): refers to the process of getting information into and out of the computer. input: those parts of the computer receiving information to programs. output: those parts of the computer that provide results of computation to the person using the computer.

Lo1: determine the relationship between input and output; lo2: assess new technologies used for input and output; and lo3: identify important characteristics of storage. An input device is any hardware component that allows you the user to enter data or instruction into the computer. there are many manual automatic input devices. At the most basic level, a computer is a device consisting of three pieces: – a processor to interpret and execute programs – a memory to store both data and programs – a mechanism for transferring data to and from the outside world. Use input data into application (eg: text into pages) typing in command to the computer (eg: shortcut key).
