Imputs & Outputs

What Is An Imput?

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.

Input and Output Devices

Input devices are things that put information IN to a computer – so, things

like a keyboard, a mouse, a microphone or a webcam.

Then there are output devices that feed information OUT of a computer –

like speakers, a monitor or a printer.

But how do input devices communicate with output devices? Well, all

information on computers has to be digitised – that means numerical data.

So all forms of information – images, text, sounds – are converted into a

single binary code.

This data, for example, represents the question, “Do you want sprouts with

that?”, which turned out to be a terrible idea for selling doughnuts.

It was input by typing on a keyboard, sent as numerical data in an email,

output on screen and printed via a printer …and then shredded.

Or, he could have input it using a wireless keyboard.

Wireless devices communicate using radio waves. When they get close

enough, they have a conversation to work out how they’re going to interact

with each other.

The screen of a smartphone or tablet computer is an input AND output

device. You input on the screen through touch, and it outputs through

graphics.

Sounds an output too. Fetch! But that’s through the speakers. Once you

know about input and output devices, you start to recognise them

everywhere. Good dog!

There are other input devices that can track and respond to your voice,

gestures or movements, and give you helpful feedback and encouragement.

Facts About Mother-Boards

  • Computer case size: Motherboards are made in different sizes, called form factors, to fit different computer cases. You'll find form factors, such as ATX or microATX, in product descriptions. This makes it easier to match your new motherboard to your old computer case or find a new case that fits.
  • Its a bit like a micro chip bigger.
  • Computer processor socket: The processor (CPU) handles the calculations and instructions for all the programs that your computer runs. This computer hardware takes the form of a chip that slips into a corresponding socket in your motherboard. Just like other computer hardware, the CPU must be compatible with your motherboard, so check to see which socket your motherboard has and look for processors that match the socket number.

  • Bus speed: The CPU socket communicates with the rest of the computer hardware on your motherboard through a bus or subsystem. The faster the bus speed, the quicker your processor can communicate with memory, boosting overall computer speed.

  • Memory (RAM) slots: Motherboards have multiple computer hardware sockets for RAM. RAM allows you computer to handle multiple programs at once, and adding additional RAM can significantly improve the speed and performance of your other computer hardware. RAM comes in multiple types (like DDR2 or DDR3). You can only use one RAM type in your computer. Even if you have multiple computer hardware slots, each slot must use identical memory sticks or modules.

  • Expansion card slots: Motherboards have expansion slots for various computer hardware components, like video cards and sound cards. As with other computer hardware, the slots must match the hardware you wish to install. The most common slot types are PCI and PCI-Express. If your motherboard features support for multiple video cards or multiple GPUs, you can use two computer hardware expansion cards together for an extra performance boost.

  • SATA and IDE interfaces: SATA and IDE interfaces allow you to connect to hard drives, optical disc drives and other computer hardware. If your motherboard has multiple interfaces and supports RAID configurations, you can use multiple hard drives on the same machine.
