Motherboard and system devices
The motherboard is the base of the modern computer system. Here are the main parts of the motherboard and its related devices:
Motherboard: The motherboard is the main circuit board in the computer where everything comes together. This is where you plug in your processor, memory, cache, video card and other cards. It is also where you connect your peripherals.
System Chipset and Controllers: Their job is to direct traffic and control the flow of information inside the computer. These circuits control the processor's access to memory, the flow of data to and from peripheral devices and communications lines, and much more. The chipset is a critical part of any computer, because it plays a big role in determining what sorts of features the computer can support. For example, which processors you can use, which types of memory, how fast you can run the machine, and what kind of system buses your PC can use, are all tied in to the type of chipset the motherboard uses.
System Buses: The system buses are the electrical channels through which various parts of the computer communicate. The physical part of these buses, the part you see, is the set of slots in the back of the machine into which you put your video card, sound card and other cards. It is over the system buses that your video card gets information from the processor, the processor saves data to your hard disk, etc.
BIOS: The system BIOS (which stands for Basic Input/Output System) is a computer program that is built into the PC's hardware. It is the lowest-level program that runs on your computer. Its job is to act as an intermediary between your system hardware (the chipset, motherboard, processor and peripherals) and your system software (the operating system). By doing this, the operating system doesn't have to be made different for every machine, which is why DOS will load on any PC. The BIOS is what runs when you turn on your computer, and what loads your operating system (for example, DOS). The BIOS also allows you to set or change many different parameters that control how your computer will function.
Cache: The system cache is a small, high-speed memory area that is placed between the processor and the system memory. The value of the cache is that it is much faster than normal system memory. Each time the processor requests a piece of data from the memory, the system first checks the cache to see if the information is there. If it is, then the value is read from cache instead of memory, and the processor can get back to work that much sooner. If it isn't, then the data is read from memory and given to the processor, but it is also placed into the cache in case the processor needs it again in the near future.
System Resources: System resources are not actual physical devices. They dictate how your PC organizes its access to various memory areas and devices. They are one of the most common areas where people have problems with the setup of their PCs: so-called resource conflicts. These are the four types of resources that various parts of your computer can sometimes decide to fight over:
Interrupts (IRQs): A device requests time from the processor using these interrupt requests. Under traditional designs, each device has a different IRQ number. If two try to use the same one, a conflict can result. Newer technologies can allow multiple devices to share an IRQ channel.
Direct Memory Access (DMA) Channels: Some devices have the ability to read and write directly from the system memory, instead of asking the processor to do it for them. Each device that does this needs its own DMA channel.
Input/Output (I/O) Addresses: Devices exchange information with the system by putting data into certain specific memory addresses. Any time information goes into or out of the machine, to your modem or hard drive or printer for example, it uses these I/O addresses. Each device needs its own memory area.
Memory Addresses: Similar to I/O addresses, many devices use blocks of memory as part of their normal functioning. For example, they may map hardware programs (BIOS code) into memory, or use a memory area to hold temporary data they are using.
