  1. What is Hardware? Hardware is the physical parts of the computer system – the parts that you can touch and see.A motherboard, a CPU, a keyboard and a monitor are all items of hardware.

  2. What is Software? Software is a collection of instructions that can be ‘run’ on a computer. These instructions tell the computer what to do. Software is not a physical thing (but it can of course be stored on a physical medium such as a CD-ROM), it is just a bunch of codes.Examples of Operating Systems (system software) - Windows 8 or Mac OS X Examples of Applications Software - Microsoft Word or Adobe Photoshop

  3. The Difference Between Hardware and Software Computer hardware is the physical components that make up the computer system. Hardware is useless without software to run on it. Software is instructions that tell computer hardware what to do. Software is useless unless there is hardware to run it on. For a computer system to be useful it has to consist of both hardware and software.

  4. Motherboard Central Processing Unit (CPU) The CPU is the 'brain' of the computer. It is the device that carries out software instructions. A motherboard is a printed circuit board found in many modern computer which holds many of the crucial components of the system. Memory Hard drive Any data or instructions that are to be processed by the CPU must be placed into main memory A hard disk drive is a hardware device that's used to store information like software and files. CD/DVD Drive Power Supply An optical disc drive that reads and writes all common CD and DVD formats. The component that supplies power to a computer.

  5. Graphics Card Sound Card A sound card is a device that attaches to the motherboard to enable the computer to input, process, and deliver sound A graphics card is a device that attaches to the motherboard to enable the computer to process and display graphics. Is a fast temporary type of memory in which programs, applications and data are stored. It stores the instructions for the computer to start up when it is turned on again. It allows you to run multiple applications at the same time. A memory that cannot be changed by a program or user. If a computer loses power, all data stored in this memory is lost. It retains its memory even after the computer is turned off.

  6. Peripheral Devices Technically, a computer need only be made up of a CPU and some RAM. But a computer like this would not be much use to anybody – other devices need to be connected to allow data to be passed in and out of the computer.The general name for these extra devices is ‘peripheral devices’. They are usually categorised into input devices, output devices and storage devices. What Are Input Devices? Devices that pass data into the computer are known as input devices. A keyboard, a mouse and a webcam are all examples of input devices. They all take information from the outside world (key presses, hand movements, images), convert them into data and then send this data into the computer for processing. What Are Output Devices? Devices that take data from the computer are known as output devices. A monitor, a printer and a loudspeaker are all examples of output devices. They all take information from the computer and convert it into real world things (images, paper hardcopy, sound).

  7. An operating system is a special piece of software that manages the general operation of a computer system: • It provides a user interface so that we can interact with the computer • It manages applications that are running on the computer, starting them when the user requests, and stopping them when they are no longer needed • It manages files, helping us save our work, organize our files, find files that we have saved and load files • It manages the computers memory, deciding what should be loaded into memory and what should be removed • It looks after computer security, preventing unauthorized access to the system • It manages the computer’s input and output hardware such as printers, etc.

  8. The system that people use to interact with a computer (to give it commands, to see the results of those commands, etc.) is known as the user interface.
