The setting Computer When you mention the word technology, most people think ab expose(predicate) selective information processors. Virtu all in ally every facet of our lives has some figurerized component. The appliances in our homes have microprocessors reinforced into them, as do our televisions. Even our cars have a computer. But the computer that everyone thinks of first is typically the personal computer, or PC.A PC is a general tool built around a microprocessor. It has lots of different split - memory, a hard plough, a modem, etc. - that work together. General use of goods and services means that you sewer do many different things with a PC. You can use it to typewrite documents, send e-mail, browse the Web and play games. On the InsideLets take a look at the main components of a typical desktop computer. Central processing unit ( mainframe) - The microprocessor brain of the computer system is called the central processing unit. Everything that a computer does is ove rseen by the CPU. reposition - This is very fast(a) storage utilise to hold data. It has to be fast because it connects directly to the microprocessor. There are several specific types of memory in a computer Random-access memory (RAM) - Used to temporarily store training that the computer is currently working with Read-only memory (ROM) - A permanent type of memory storage used by the computer for important data that does not change Basic input/output system (BIOS) - A type of ROM that is used by the computer to establish rudimentary communication when the computer is first turned on Caching - The storing of frequently used data in extremely fast RAM that connects directly to the CPU Virtual memory - Space on a hard disk used to temporarily store data and swap it in and out of RAM as needed Motherboard - This is the main circuit board that all of the other internal components connect to. The CPU and memory are normally on the motherboard. Other systems may be found directly on the motherboard or connected to it through a secondary connection. For example, a safe card can be built into the motherboard or connected through PCI. Power supply - An electrical transformer regulates the electricity used by the computer. rugged disk - This is large-capacity permanent storage used to hold information such as programs and documents. Operating system - This is the basic software that allows the user to interface with the computer.
