A Motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. If you were to ever open your computer the biggest piece of silicon you see would be the motherboard. Each motherboard has a collection of chips and controllers known as chipsets. (Techterms, Motherboard) A chipset is a group of integrated circuits that work together. It may refer to the design of a single component or may describe the relationship of multiple components within a computer system. For example, the chipset of a video card describes the design of the card, while a motherboard chipset described its layout and the different components it supports. (Techterms, Chipset)
Another name for system unit is a computer case. Cases are usually constructed from steel or aluminum. Plastic has sometimes been used other materials such as glass, wood and even Lego blocks have appeared in home built cases. (Wikipedia, Computer cases)
A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit. The microprocessor is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. It is an example of sequential digital logic, as it has int...

...es of memory, motherboards, CPU’s, RAM’s and a lot of other terms are all about what a system unit is. The motherboard is the main brain of the system and it is basically what everything else has to run off of or go through to run. The system unit is a very important object in computers and without this we wouldn’t have computers that would run properly.

- Includes large program code and mathematic equations There are many times that computers can help humans do things that could not be done by hand. Many of these things can be expressed mathematically as a sum but can not be calculated on paper because of the extremely large number of simple calculations. The example that I've been working with is the sum of electric fields and the field lines they can produce. It is easy to acquire the electric field vector due to a set of charged particles at a given point, but to create a smooth line that follows those vectors requires more computing power than just a paper and pencil....   [tags: physics computer program programming]
