Inputs and outputs

Inputs and outputs

Inputs are outputs are similar but do different things.

  • A input is where you have entered some data or information in to a computer for processing or for use. In other words, you have commanded the computer to do something, like text typed or data entered, it can be as simple as moving the mouse or as complex as scanning a document. Examples of input devices are: keyboard, a digital camera, mouse or a scanner. Once input this then can transfer to output. Without a input, you can't have a output.
  • A output is generated by different devices, depending on the device, this includes data produced at a sofeware level, such as the result of a calculation or at a physical level, such as a printed document. Devices that produce physical output from the device are called output. Such as speakers, they would be commanded to play music and then the speakers would output the music.

Computers and disabilites

If someone has a disability, (depending on that disability) they may not be able to do something that someone without a disability could do. With computers, they are loads of different solutions that suit peoples needs and helping to reduce problems.

  • If someone has missing limbs and is in a wheelchair, then maybe a laptop is best because it's portable and can be moved around.
  • If someone has trouble seeing the keyboard, then having a keyboard with colours on it, will make the letters stand out, therefore making someones life easiler on the computer.
