Introduction To Computer Pdf Pdf A computer is an electronic device, operating under the control of instructions stored in its own memory that can accept data (input), process the data according to specified rules, produce information (output), and store the information for future use1. This chapter reviews it certifications and the components of a basic personal computer (pc) system. this course focuses on desktop and laptop computers. it also discusses electronic devices, such as personal digital assistants and cell phones.
Introduction To Computer Systems Pdf Computer Data Storage When you withdraw cash from an atm, scan groceries at the store, or use a calculator, you're using a type of computer. personal computers come in two main styles: pc and mac. both are fully functional, but they have a different look and feel, and many people prefer one or the other. Input: a computer accepts data that is provided by means of an input device, such as a keyboard. processing: a computer performs operations on the data to transform it in some way. output: a computer produces output on a device, such as a printer or a monitor, that shows the results of processing operations. Computers perform four basic operations — input, process, output, and storage. these operations comprise the information processing cycle. collectively, these operations process data into information and store it for future use. The six primary components of a computer are input devices, the processor (control unit and arithmetic logic unit), memory, output devices, storage devices, and communications devices.
