what arethe basic parts of a computer and their definition?

Answer 1

I can recommend an excellent book for you... called A+ Certification by Michael Meyers and Scott Jernigan. It explains every part of the computer in layman terms (which means its not to techie). It has pictures of everything they are talking about and is an excellent book on hardware. But here are some basic things about a computer definitions as from the website (http://www.webopedia.com/)

CPU - Abbreviation of central processing unit, and pronounced as separate letters. The CPU is the brains of the computer. Sometimes referred to simply as the processor or central processor, the CPU is where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.
On large machines, CPUs require one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single chip called a microprocessor.


Motherboard - The main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset.
On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster PC by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely.

Memory - Internal storage areas in the computer. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk.
Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information.

There are several different types of memory:

RAM (random-access memory): This is the same as main memory. When used by itself, the term RAM refers to read and write memory; that is, you can both write data into RAM and read data from RAM. This is in contrast to ROM, which permits you only to read data. Most RAM is volatile, which means that it requires a steady flow of electricity to maintain its contents. As soon as the power is turned off, whatever data was in RAM is lost.
ROM (read-only memory): Computers almost always contain a small amount of read-only memory that holds instructions for starting up the computer. Unlike RAM, ROM cannot be written to.
PROM (programmable read-only memory): A PROM is a memory chip on which you can store a program. But once the PROM has been used, you cannot wipe it clean and use it to store something else. Like ROMs, PROMs are non-volatile.
EPROM (erasable programmable read-only memory): An EPROM is a special type of PROM that can be erased by exposing it to ultraviolet light.
EEPROM (electrically erasable programmable read-only memory): An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge.

Answer 2

OK - Basic Parts:
1)Processor - basically the brain that take in information, processes it and then 'outputs'
2) The motherboard in which the information travels (the motherboard is very important because if the 'roadwork' is efficient, the processor will be faster than if it was a poorly designed motherboard.
3) Memory: The RAM (Random Access Memory) is "volatile"... That means that what you see on the screen is not stored and if you lose power, you lose what's on your screen. I think of it as "lala land" memory..... it appears but it doesn't mean anything until you hit the 'store button'....

With computers, the thing to remember is buy as much as you can afford - and 'more' is typically better. Junk in - junk out....

Answer 3

Catholicism came first. The word 'Catholic' means 'universal', 'including all Christians or all of Western Church'. Catholics were the first Christians. Roman Catholic Church (in Vatican) is the first official Christian Church. Catholicism came from Judaism and by AD 394 Christianity became the official religion of the Roman empire. It is after the Reformation during the 16 th century that Roman Catholicism split and had 2 other branches - Protestantism and Orthodoxy . Roman Catholicism, Protestanism and Orthodoxy are the three major branches or denominations of Christianity. These three major branches and some 'Other' Christians are together known as Christianity. So if you are a Catholic that means you are a Christian. When you introduce yourself it is more easy for others to understand and more comfortable for you when you say ' I am a Christian' or 'I am a Christian - Catholic' than 'I am a Catholic'.

Answer 4

That would be a bit to type in here. Ill type to you a a list and definitions through email if possible. Email me at [e-mail], with speciafically what of this you need to know

Answer 5

The memory, data storage, and cpu.
