Internal Parts of a Computer by Shawn McClain A modern computer may contain hundreds of different controllers and chips, but even the most complicated of machines can be boiled down to a few simple parts. Understanding just these parts can give you an excellent idea of how a computer operates, and this knowledge can allow you to make better purchasing decisions the next time you are shopping for a system. Motherboard The motherboard is the main circuit board that all other computer components either sit in or are connected to. The motherboard type will determine what kind of processor and memory chips can be installed on the computer, along with what kind of external connections, such as USB, are natively supported.
3.1. Introduction to Computers
The Computer Cache Memory Cache memory is a small block of high-speed memory RAM that enhances PC performance by pre-loading information from the relatively slow main memory and passing it to the processor on demand. Most CPUs have an internal cache memory built into the processor which is referred to as Level 1 or primary cache memory. This can be supplemented by external cache memory fitted on the motherboard. This is the Level 2 or secondary cache.
In modern computers, Levels 1 and 2 cache memory are built into the processor die. If a third cache is implemented outside the die, it is referred to as the Level 3 L3 cache. Expansion Bus PCI slots. Expansion boards cards plug into the bus. PCI is the most common expansion bus in a PC and other hardware platforms.
Buses carry signals such as data, memory addresses, power, and control signals from component to component. Expansion buses enhance the PCs capabilities by allowing users to add missing features in their computers by slotting adapter cards into expansion slots. Chipsets The Computer Chip-sets A chipset is a group of small circuits that coordinate the flow of data to and from a PC’s key components.
These key components include the CPU itself, the main memory, the secondary cache, and any devices situated on the buses. A chipset also controls data flow to and from hard disks and other devices connected to the IDE channels. A computer has got two main chipsets: The NorthBridge also called the memory controller is in charge of controlling transfers between the processor and the RAM, which is why it is located physically near the processor.
The term “bridge” is generally used to designate a component which connects two buses. Using a quartz crystal, the CPU clock breathes life into the microprocessor by feeding it a constant flow of pulses. Similarly, in any communications device, a clock may be used to synchronize the data pulses between sender and receiver.
A “real-time clock,” also called the “system clock,” keeps track of the time of day and makes this data available to the software. Switches and Jumpers The Switches and Jumpers DIP Dual In-line Package switches are small electronic switches found on the circuit board that can be turned on or off just like a normal switch. They are very small and so are usually flipped with a pointed object, such as the tip of a screwdriver, a bent paper clip, or a pen top.
Take care when cleaning near DIP switches, as some solvents may destroy them. Dip switches are obsolete and you will not find them in modern systems.
Jumper pins are small protruding pins on the motherboard. A jumper cap or bridge is used to connect or short a pair of jumper pins. When the bridge is connected to any two pins, via a shorting link, it completes the circuit and a certain configuration has been achieved. Jumper caps are metal bridges that close an electrical circuit. Typically, a jumper consists of a plastic plug that fits over a pair of protruding pins.
Jumpers are sometimes used to configure expansion boards. By placing a jumper plug over a different set of pins, you can change a board’s parameters. This is a good book for those who want to know much more about computer hardware. I have used the book on numerous occasions and Mike Meyers never disappoints.

Modems have not gone away, as broadband connections are not available in all areas, but they are disappearing. A standard telephone modem uses your existing analog telephone line at speeds up 56 Kbps.
