What is input output ports?

What is input output ports?

(1) (Input/Output port) An I/O port is a socket on a computer that a cable is plugged into. The port connects the CPU to a peripheral device via a hardware interface or to the network via a network interface. See port, standards – hardware interfaces, DisplayPort, HDMI and USB.

What are the different input and output ports?

Input Output Ports

  • Serial Port : Used for external modems and older computer mouse.
  • Parallel Port : Used for scanners and printers.
  • Universal Serial Bus (or USB) Port : It can connect all kinds of external USB devices such as external hard disk, printer, scanner, mouse, keyboard, etc.
  • Firewire Port :
  • Ethernet Port :

What is input and output devices?

An input device is something you connect to a computer that sends information into the computer. An output device is something you connect to a computer that has information sent to it.

What are examples of input ports?

Serial port, a computer hardware interface. Universal Serial Bus, a computer hardware interface. IEEE 1394 interface, a computer hardware interface, known commonly as Firewire. PS/2 connector, a common computer interface for mice and keyboards.

What is Input Output?

Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to “perform I/O” is to perform an input or output operation.

What is input port function?

Input ports. It performs the physical layer functionality (shown in light blue in Figure 4.6-1) of terminating an incoming physical link to a router. Control packets (e.g., packets carrying routing protocol information such as RIP, OSPF or IGMP) are forwarded from the input port to the routing processor.

How many input output ports are there in 8051?

8051 microcontrollers have 4 I/O ports each of 8-bit, which can be configured as input or output. Hence, total 32 input/output pins allow the microcontroller to be connected with the peripheral devices.

What is difference between input and output?

An input device sends information to a computer system for processing, and an output device 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.

What are the five input and output devices?

Input and Output Devices

  • Keyboard.
  • Mouse.
  • Microphone.
  • Bar code reader.
  • Graphics tablet.

Which of the following port is used for only input output?

Features of Port 1: Address is 90H. Construction: Port 1 has one D latch, two unidirectional buffers, 1 FET, and one internal pull-up resistor at each pin. It has only one function – to act as an Input-Output port.

What is the use of input and output function?

Input means to provide the program with some data to be used in the program and Output means to display data on the screen or write the data to a printer or a file. The C programming language provides standard library functions to read any given input and to display data on the console.
