Computer Storage Pdf The document provides an overview of input and output devices in information technology, detailing various types of input devices such as keyboards, pointing devices, scanning devices, image capturing devices, and audio 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.
Storage Devices Pdf Byte Computer Data Storage These activities can be grouped in four functional categories, viz., data input, data processing, data output and storage, constituting what is known as a data processing cycle. All the keys are mapped and stored in the memory. to put it simply, keyboards use switches and circuits to change keystrokes to a format the computer understands. every keyboard contains a processor that does the work of translating the keystrokes, or the keys pressed, to the computer. 1.1 introduction this unit introduces you to the basics of computer concepts and terminology to help you understand and identify fundamental elements of computer hardware and software. Computer is an electronic device that receives input, stores or processes the input as per user instructions and provides output in desired format. computer input is called data and the output obtained after processing it, based on user’s instructions is called information.

Primary storage is a fast memory that operates at electronic speed. programs must be stored in the memory while they are being executed. secondary storage is used when large amounts of data & many programs have to be stored. eg: magnetic disks and optical disks(cd roms). Von neumann architecture: this model, prevalent in modern computers, describes how instructions and data are stored in the same memory space, allowing the cpu to access both seamlessly. Other components also are included, of which the critical ones are a keyboard for data input, a screen (monitor) for information display, memory chips for temporary storage, and a hard disk for data storage. It consists of every mechanical and electrical component. it is a pointing device that controls the location of the pointer (arrow or cursor) on the screen. when the user presses on the one of buttons, the pointer (mouse) either marks a place on the screen or marks selection from data on the screen. ii. keyboard. iii. scanner. iv. microphone.
