This Computer awareness arihant pdf is important for all competitive exams, especially for enhancing computer awareness and for sarkari naukri preparation. As a Computer Technician, you are responsible for the establishment and maintenance for all computer systems at a given company. The student will demonstrate proficiency in the use of a select from the choices below : a.
A device that accepts data, processes the data in accordance with a stored program, generates results, and usually consists of input, output, storage, and arithmetic, logic, and control units. Convert it into electrical signals and transmit it to the processor. Input device: Usually a keyboard or mouse is used to read data and programs into the computer.
Output device: A display screen, printer, etc. Mass storage device: It allows a computer to permanently store large amounts of data. Common mass storage devices include disk drive and tape drive. It lets the computer's logic unit, memory, as well as both input and output devices know how to respond to instructions received from a program.
It performs both bitwise and mathematical operations on binary numbers and is the last component to perform calculations in the processor. Memory: - Computer memory is any physical device capable of storing information temporarily or permanently. Registers: - Register are used to quickly accept, store, and transfer data and instructions that are being used immediately by the CPU, there are various types of Registers those are used for various purpose.
Program Counter: A program counter is a register in a computer processor that contains the address location of the instruction being executed at the current time. Accumulator Register: In a computer's central processing unit CPU , an accumulator is a register in which intermediate arithmetic and logic results are stored. Index Register: An index register is a circuit that receives, stores, and outputs instruction-changing codes in a computer. This circuit is also called an address register or a register of modifications.
Memory Buffer Register: A memory buffer register MBR is the register in a computer's processor, or central processing unit, CPU, that stores the data being transferred to and from the immediate access store.
It contains the copy of designated memory locations specified by the memory address register. RAM , or the data after a fetch from the computer storage. OCR optical character recognition is the recognition of printed or written text characters by a computer. Analysis of the scanned-in image, and then translation of the character image into character codes, such as ASCII, commonly used in data processing.
MICR magnetic ink character recognition is a technology used to verify the legitimacy or originality of paper documents, especially checks. Bar-code readers are photoelectric scanners that read the bar codes or vertical zebra striped marks, printed on product containers. This is an input device that enables you to enter drawings and sketches into a computer. Scanner is an input device that can read text or illustrations printed on paper and translate the information into a form that the computer can use.
Mouse is a device that controls the movement of the cursor or pointer on a display screen. It is a small object you can roll along a hard and flat surface. Light pen is an input device that utilizes a light-sensitive detector to select objects on a display screen. NIOS Notes.
Input Devices: Input devices are the component of the computer system that accepts incoming data and instructions and converts them into a pattern of electrical signals in binary code that is understandable to a digital computer. Example: Keyboard, mouse etc. Output Devices: Output devices are the component of computer system that converts the digitized signals into a form understandable to the user. The output devices are generally known as reverse of input devices. Output devices also send data from one computer system to another. Attention reader! Writing code in comment?
Input Device in Hindi. इनपुट डिवाइस को दो श्रेणियों में विभाजित किया गया है. Online Input Device.
Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two. An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer. An output device reverses the process, translating the digitized signals into a form intelligible to the user.
The Input Devices are the hardware that is used to transfer transfers input to the computer. The data can be in the form of text, graphics, sound, and text. Output device display data from the memory of the computer.
Updated: by Computer HopeAn sends information to a computer system for, and an reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device. Most devices are only input devices or output devices, as they can only accept data input from a user or output data generated by a computer.
A device that accepts data, processes the data in accordance with a stored program, generates results, and usually consists of input, output, storage, and arithmetic, logic, and control units. Convert it into electrical signals and transmit it to the processor.
