Input and Output devices are a major part of the computer. They are a type of hardware device that makes up the computer system. These allow the system to function properly with external help. They both deal with data but in different ways. <\/span><\/p>\n

The input allows the user to send data while the output completes the task related to the data. These all are auxiliary devices that connect to the device and complete all the tasks accordingly. Keyboards, mouse, scanners, etc are some of the input devices while printers, monitors, headphones, etc are some of the output devices.\u00a0<\/span><\/p>\n

Another important element of a hardware system is <\/span>computer memory<\/b>. It is where all the data goes either temporarily or permanently. It is mainly of two types – volatile memory and nonvolatile memory. <\/span>Volatile memory<\/span> needs the power to function and store information like static RAM or dynamic RAM. <\/span><\/p>\n

Dynamic one is complicated to handle in terms of interface and thus requires regular refresh cycles. Meanwhile, SRAM has a better interface but requires six transistors per bit. <\/span>Non Volatile Memory<\/span> doesn’t require power to retain information and some of the examples are – ROM, Flash memory, Optical Disks, etc.\u00a0<\/span><\/p>\n

Input Devices of Computer<\/h2>\n

As mentioned above the input devices allow the users to send signals to the computer to perform a certain task. The receiver at this end is the Central Processing Unit (CPU) which then sends the signal to the output devices. Input devices further classify according to modality like visual or audio, discrete or continuous, and is it direct or indirect. <\/span><\/p>\n

Some of the classifications are –\u00a0<\/span><\/p>\n
