Computers Inside and Out

Computer A computer is an electronic device that processes data and stores it. The data that is stored in a computer is in binary form ( in 1s and 0s). It makes decisions based on the input given in a variable program.

Keyboard A keyboard is an input device that lets the input data and tell the computer what to do. Commonly keyboards are made up of keys (Either physical or on screen) that have a programmed responses to when the keys are pressed.

Cooling Devices Cooling devices are used to dissipate excess heat created by the components of the computer. Common types of cooling devices in computers include: Computer fans that circulate air in the computer therefore cooling it. Another type of cooling device is a heatsink that uses liquid to transfer heat from components out of the computer.

Ram Random Access Memory is a form of computer data storage that stores the data and machine code currently being used. This allows the computer to multitask and a have more than one program running at a time. The more RAM you have the more multitasking your computer can do.

Input Any command given to the computer is input. (example: typing, clicking items with the mouse etc.) input is sent to the computer using an input device. (example: keyboard, mouse etc.)

Output Output devices receive commands and data from the computer and project them ( Most commonly a display) to show progress in a program or commands. Examples of output devices include speakers or monitors.

Mouse A computer mouse is a handheld input device most commonly used to move a pointer two dimensionally across a display. It detects movement through optical sensors and can be used to select items on the display.

OS An operating system (OS) manages computer programs and systems. It is the bridge between input and output devices (example: from keyboard to screen). The operating system allows the to access the functions of the computer.

U U (Central Processing Unit) is essentially the brain of the computer. It makes decisions and carries out commands.

Hard Drive Hard drives are the long term memory of a computer. It re files and keeps them to be opened at a later time. It also holds the software that the computer runs.

Motherboard The motherboard is a chip that allows communication between the devices in the computer. Many peripherals or “extra devices” such as the video card communicate through the motherboard.

Microprocessor The microprocessor make the decisions in the computer that are necessary for it to run. The microprocessor is connected to the motherboard and make decisions for the motherboard in 1 or 0.The better the microprocessor the faster it can make decisions and therefore the computer runs faster.

Hardware Computer hardware are the physical parts of the computer (example: keyboard, mouse monitor etc.). Hardware is instructed to execute any command or instruction by the software.

Software Software is the set of instructions inside the computer that actually runs the systems. It can only be run alongside hardware as the hardware tells the software what to do and vice versa.
