Is a hard drive an input or output device?

Floppy and hard disk drives are both input and output devices because the CPU can either read data from them or write data to them. A CDROM drive, on the other hand, is an input device only because it cannot be written to by the CPU.

Furthermore, is a DVD drive an input or output device?

CD and DVD drives are also input devices, since they read data into the computer. Another classification of a peripheral is an output device. A CD or DVD burner would also be an I/O device, since it can both read and write data to discs.

Is a USB port an input or output device?

“USB” refers to Universal Serial Bus, which is a type of connection used to link computers to peripheral devices. USB ports are found on both the computers and the devices, and USB cables connect them to each other. USB ports function as both input and output ports.

Is a printer an input or output device?

If a device is putting data into the computer in the form of text, sound, images, button presses etc. then it is an input device, if the device is outputting things from the computer such as sound, movement, printing, images etc., then it is an output device. Therefore it is an input device.

Is a keyboard A input or output device?

A keyboard is an input device that sends information about the keys you press. This is received by the computer and it displays the correct letter or number. A monitor is an output device. It displays all the information that has been sent to it by input devices.

Is a modem an input or output device?

The modem is an input and an output device. It is used for sending and receiving information and data over telephone lines. There are at least two ways that can be used to represent data and information electronically. One way is digital and another way is analogue.

Is a motherboard an input or output device?

A motherboard is one of the most essential parts of a computer system. It holds together many of the crucial components of a computer, including the central processing unit (CPU), memory and connectors for input and output devices.

Is a ram an input or output device?

Random Access Memory (RAM) RAM is perhaps the most important of the input/output devices. When we talk about computer memory, we are mainly talking about RAM. This means that the CPU can ‘look’ at any address in RAM and get the contents of that address.

Is a CD ROM input or output device?

CD-ROM or Compact Disk, Read Only Memory is an Input “Medium” not Device. CD-R, CD-RW on the other hand are Input/output “Medium”. However, if the drive and the media support Write operations, then it is also an output device. Most current devices in a computer do both so they are I/O devices.

Is a scanner input or output device?

Input Devices. The computer mouse and scanner fall under the input device category. As the name suggests, input devices are used to send information to the computer. A mouse is used to input the movements of a cursor, while a scanner is used to input physical media into digital format.

Is a light pen an input or output device?

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer’s CRT display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy.

Is hard disk a storage device?

A hard disk drive (HDD), hard disk, hard drive or fixed disk is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.

Is a floppy disk a storage device?

A floppy disk, also called a floppy, diskette, or just disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive (FDD).

Which device is CPU?

The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program. This program will take inputs from an input device, process the input in some way and output the results to an output device.

Are Zip disks rewritable?

The Zip drive is a removable floppy disk storage system that was introduced by Iomega in late 1994. The final versions of the disk reached 750 MB, the capacity available on rewritable CDs, which was far surpassed by the later rewritable DVDs.

Is floppy disk a secondary storage device?

Auxiliary memory, also known as auxiliary storage, secondary storage, secondary memory or external memory, is a non-volatile memory (does not lose stored data when the device is powered down) that is not directly accessible by the CPU, because it is not accessed via the input/output channels (it is an external device).

What is an example of a secondary storage device?

A secondary storage device refers to any non-volatile storage device that is internal or external to the computer. It can be any storage device beyond the primary storage that enables permanent data storage. A secondary storage device is also known as an auxiliary storage device or external storage.

What are the three main types of secondary storage?

Currently the most common forms of secondary storage device are:

  • Floppy disks.
  • Hard disks.
  • Optical Disks.
  • Magnetic Tapes.
  • Solid State Devices.
  • What are the 3 types of storage?

    There are three main categories of storage devices: optical, magnetic and semiconductor. The earliest of these was the magnetic device. Computer systems began with magnetic storage in the form of tapes (yes, just like a cassette or video tape). These graduated to the hard disk drive and then to a floppy disk.

    What are the different types of secondary memory?

    Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk is usually contained inside the case of a computer. The hard disk is used for long-term storage of programs and data.
