Computer Information
The IT world
By Gavin Viall
It was said that the reason for information systems is to get the right information to the right person or people at the right time, and the right amount, and in the right format. One of the main goals in an information system is to process data into information. So Data input becomes very important. We are going to look at five situations, and determine which method of data input works best for that situation. The input devices for operating systems are as follows Keyboard, mouse, microphone, camera, video, touch screen, pen and pad. Output devices are hardware that allows the computer to communicate to the end user. The output devices are as follows monitors, speakers, printers, projectors, and mechanical devices (including robotics). A computer can only do simple things. Now they can do simple things, but with great speed and accuracy. Computers perform input and output from memory and storage. A computer can also perform simple mathematics and logic. A computer’s main processing parts are as follows: Central processing unit (this is the chip that computes and controls). The bus is another piece of a computers main processing unit. The bus is a set of wires that transfers data from computer to component. The basic input / output system is the chip that boots a computer. The last processing device is the controller. The controller is hardware that manages the transfer of data from computer to the device. The storage devices for a computer are where all saved data will be located. Your primary storage for a computer is called random access memory or (RAM) for short. Random access memory is memory that the computer uses to go directly to byte of information without having to go search through the storage location sequentially. There are mainly six types of secondary storage Floppy disk, hard disk, CD, Card, Tape, and flash thumb drive. A computers network provides connectivity between...
