The motherboard has been an integral part of most personal computers for more than 20 years. The motherboard contains various circuit cards performing various functions all plug into many similar sockets on a common circuit board. Each circuit card performs a unique function in the computer and gets its power from the socket.
The motherboard contains many circuits and slots, but let's focus on some of the important ones. The motherboard is home to the processor (CPU) along with the access slots and RAM.
If we look at the diagram above I've labeled the parts of the motherboard that I wanted to discuss. The objects labeled 1 are the access slots. 2 is the processor slot and 3 are slots to hold memory (RAM).
The CPU, or processor, is the heart of your computer no matter what type (PC, Server, and Laptop). There are many brands for processors such as Intel and Athlon all with different processors for your computer. The CPU processes everything that your computer does, therefore the better the processor, the faster the computer.
Random Access Memory (RAM) is the form of memory contained in most computers. RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell. When an application is running it stores its information in the RAM. When you close the application the information is deleted from the RAM. This is why you need certain amounts of RAM to run applications. The more RAM you have the faster your computer will be, and the more applications you'll be able to run without loosing speed.
Nearly every desktop computer and server in use today contains one or more hard-disk drives. These hard disks do one thing well - they store changing digital information in a relatively permanent form. They give computers the ability to remember things when the power goes out.
A hard drive stores all your files and information in a permanent form unlike storing it in RAM (which is temporary). The larger your hard disk (drive) the more information and files you're able to store. Today's average hard drive is 40 GB although slowly 80 GB hard drives are becoming used more often.
The CD-Rom is quite simple, it reads CD's. CD-Rom completely stands for Compact Disk Read Only Memory. The revolution of CD's is that they hold much more data than a floppy disk, although are not as flexible when it comes to rewriting and storing personal data.
Using CD-RW you can make your own CD's and use them more like a floppy disk. These are becoming more and more popular although you still need a CD-Rom to read them.
A floppy drive reads the popular floppy disk. Floppy disk are easy to use, rewritable, compact, and great for storing information. The floppy drive is simple and allows you to read, write to, and write over information stored on a floppy disk.
Now you have a basic knowledge of the parts of your own PC. In the future you'll be able to read more advanced articles and have an understanding of the parts of a PC.
