Processor
processor
- A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.
The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor.

Expansion Slots

With technology changing so quickly, it's a wonder our computers don't become obsolete a month after we buy them. Without a way to expand a computer's capabilities, the world would quickly fill up with oversize paperweights and doorstops.
Thank heaven for the far-thinking propeller-heads who dreamed up internal expansion slots -- the ubiquitous feature on personal computers that helps keep the world safe from massive silicon junk piles.
Most desktop varieties of IBM-compatible and Macintosh computers have at least one expansion slot -- a thin strip that locks an expansion card in place on the motherboard inside your computer. These expansion cards add functions that you might not have been able to use before, including things like sound, a fax-modem, high-resolution graphics or connections to local area networks.

Memory

The different types of computer memory that you have the opportunity to purchase for your computer system have increased drastically over the years. Your options are limitless when it comes to upgrading and updating all aspects of your computer system. All you have to do if you are not sure about what kinds of software that you should consider purchasing is either use a guide from the computer store, informing you about all of the different types or you could just get on the internet, like you are now, and browse around, you
will find a huge variety of different programs that could help your computer system run more efficiently and quickly. Having the double date rate (DDR) memory for your computer system is by far the greatest type of memory to install onto your computer system because it offers you so many improvements within your computer and to be quite honest, it is very much an affordable type of computer memory to have on your home computer system, for your enjoyment. This type of memory has become much needed for computer users as well as becoming a very popular feature that most would want.

Motherboard
A motherboard is the central or primary circuit board making up a complex electronic system, such as a modern computer. It is also known as a mainboard, baseboard, system board, or, on Apple computers, a logic board, and is sometimes abbreviated as mobo.[1]
Most after-market motherboards produced today are designed for so-called IBM-compatible computers, which hold over 96% of the personal computer market today.[2] Motherboards for IBM-compatible computers are specifically covered in the PC motherboard article.
The basic purpose of the motherboard, like a backplane, is to provide the electrical and logical connections by which the other components of the system communicate.
A typical desktop computer is built with the microprocessor, main memory, and other essential components on the motherboard. Other components such as external storage, controllers for video display and sound, and peripheral devices are typically attached to the motherboard via edge connectors and cables, although in modern computers it is increasingly common to integrate these "peripherals" into the motherboard.
