Computer Basics
Have you ever thought about the components that make-up a computer? If you are like most, you have not given it a thought. A computer is a collection of hardware designed to run programs using software to accomplish tasks. The main component of your computer is the main board sometimes referred to as the motherboard. The central processing unit is the actual computer in the computer and functions to execute instructions to read from and write to memory and input/output (IO) devices as well as perform math operations.
- Hardware - The physical parts of a computer system. (i.e. monitor, keyboard, system unit, mouse, etc.)
- Software - Computer instructions or data.
- Main Board - The physical circuit board in a computer that contains the central processing unit (CPU) and other basic components.
Roll over the image to see descriptions. The function of each component is provided below in the table. How many of these statements accurately describe your own personal choices? The more you resonated with, the healthier your lifestyle.
The function of each component is provided in the table below:
| Motherboard Component | Function |
|---|---|
| Rear Connectors |
Allows external devices to be connected to the computer. |
|
Memory Slots |
Allows computer memory to be inserted into the computer. Also referred to as a RAM slot. |
|
CPU Socket |
The connector on the motherboard that houses a CPU and forms the electrical interface and contact with the CPU. |
|
Integrated Drive Electronics (IDE) Port |
These are 40 pin connectors that provide a place to connect the ribbon cables from the drives (hard and CD/DVD). All data between the motherboard and the drives is carried in these cables. |
|
Serial ATA (SATA) Ports |
These components connect via cables to various storage devices. |
|
Peripheral Component Interconnect (PCI) Slots |
Allows components to be placed directly into the motherboard. |
|
Peripheral Component Interconnect (PCI) Express Slots |
This type of PCI slot is full-duplex which means data is sent and received at the same time. |
