Computer Input And Output Devices Pdf Input instruction is used to transfer data from i o device to cpu, store instruction is used to transfer data from cpu to memory and output instruction is used to transfer data from cpu to i o device. • the very first computers only accepted "punch cards" as input. computer scientists had to carefully punch out their instructions and then feed the cards into the computer.
Lecture 4 Input Output Pdf Computer Science Electricity In this paper, we describe an alternative output method for silicon auditory models, suitable for direct interface to digital computers. this brief review of the state of the art in output devices is written from a perspective of two basic questions. All types of computer follows a same basic logical structure and perform the following five basic operations for converting raw input data into information useful to their users. Only read bar codes. the input device converts the data into the computer's own internal code before sending it to the cpu. 2. it describes the basic components and working of a computer including input, storage, processing, and output. 3. the characteristics of computers are discussed such as speed, accuracy, diligence, versatility, ability to store data, and lack of feelings.

Input is any data and instructions entered into the memory of a computer. instructions can be entered into the computer in the form of programs, commands, and user responses. program: a series of related instructions that tells a computer what tasks to perform and how to perform them. The unit 4 presents the information of input and output devices. a number of input output devices are used with many types of microcomputers. many of these are less complex versions of i o devices that have been available for larger computer systems. A computer consists of three main components—(1) input output (i o) unit, (2) central processing unit (cpu), and (3) memory unit. the computer user interacts with the computer via the i o unit.
