Mell Can a computer accept data?
A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse. Input devices accept data in a form that the computer can use; they then send the data to the processing unit.
What data does a computer accept?
The main types of data that can be input into a computer and processed are numeric, text, dates, graphics and sound.
Is data a computer hardware?
Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware.
What are the different types of computer hardware?
With the using of input hardware components can be inserted the input to computer, and retrieve the useful output with the help of output hardware devices. Every computer parts have own unique function, so we explain types of computer hardware and their functions. 2. Processing Devices 3. Output Devices
Which is the most common input device on a computer?
Pointing Devices. A computer mouse. Pointing devices are the most commonly used input devices today. A pointing device is any human interface device that allows a user to input spatial data to a computer. In the case of mice and touchpads, this is usually achieved by detecting movement across a physical surface.
What kind of data can a computer process?
Some of the ways a computer can process data include performing calculations, sorting lists of words or numbers, modifying documents and pictures according to the user instructions, and drawing graphs. A computer processes data in a device called the central processing unit or CPU. A computer must store data so it is available for processing.
What are the devices attached to a computer called?
The Complete Hardware System. The hardware devices attached to the computer are called peripheral equipment. Peripheral equipment includes all input, output, and secondary storage devices. In the case of personal computers, some of the input, output, and storage devices are built into the same physical unit.
