4. CPU The CPU or Central Processing Unit is the "brain" of the computer, it is the 'compute' in computer. Without the CPU, you have no computer. Computer CPU's (processors) are composed of thin layers of thousands of transistors. Transistors are tiny, nearly microscopic bits of material that will block electricity when the the electricity is only a weak charge, but will allow the electricity pass through when the electricity is strong enough. £226,002.89 £0.99 HIGHEST AND LOWEST PRICES PRICE DIFFERENCE = £226,001.90

5. HARD DRIVE A hard disk is part of a unit, often called a "disk drive," "hard drive," or "hard disk drive," that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of surfaces. Today's computers typically come with a hard disk that contains several billion bytes (gigabytes) of storage. £0.99 £224,988.24 HIGHEST AND LOWEST PRICES PRICE DIFFERENCE = £224,987.25

6. RAM RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers. £33,690.00£0.99 HIGHEST AND LOWEST PRICES PRICE DIFFERENCE = £33,689.01
