What is a System Unit?
A system unit is the main part of a personal computer. The system unit includes the chassis, microprocessor, main memory, bus, and ports but this does not include the keyboard or monitor, or any peripheral devices (Enterprise). A system unit is also known as a “Tower” or “Chassis”. It is the main part of a desktop computer. It also includes the motherboard, CPU, RAM and other components. (Techterms, System Units)
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.

1. A device is a computer if it has an input device, central processing unit (CPU), internal memory, storage, and an output device.
a. Central Processing Unit (CPU) The Central Processing Unit is the primarily segment of a computer system that executes the computer’s functions. It also performs instructions from computer programs. The CPU controls the operating system and applications, continually receiving input from software programs or user and producing output.
Building a gaming computer may be an intimidating endeavour, but in all actuality with a little hard work anyone can be a whiz at putting together a gaming computer. Why build a custom gaming PC? Well it’ll save money, and give the builder a great experience. It’s always fun to learn how different things work. The price of a top of the line retail gaming computer runs from two thousand on up to five thousand dollars and beyond, a monitor alone could cost one thousand dollars. The two types of gaming PC builds are , the hardcore gamer build which will cost a little extra, and the casual gamer build which isn’t as expensive; moreover, the steps in building a gaming PC are: creating a budget, researching what the builder/user wants the PC to be used for, and purchasing the equipment.

It contains the circuitry printed on a flat board. Motherboard connects microprocessor to all other parts of computer and devices attached. Microprocessors, memory modules, BIOS chip and other ROM chips, system clock, display adapters, build-in VGA and NIC, AGP and PCI expansion slots and so on are housed on motherboard.

Figure 1 represents the microarchitecture of a typical superscalar processor. It includes instruction fetching and branch prediction, decode and register dependence analysis, issue and execution, memory operation analysis and instruction reorders and commit.
The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)
A microprocessor, as the term has come to be known, is a general- purpose digital computer central processing unit (CPU).
Inside the CPU are registers, arithmetic and logic units (ALU), a floating-point unit (FPU), control circuitry and cache memory. Registers are circuits designed to hold data so that it can be processed in some way by an ALU or the FPU. Cache memory is extremely fast, but small relative to the main memory. Cache memory is used to store the current set of working data and code. So when the processor needs to read the next bit of data or code, usually it can retrieve it much faster from the cache. On occasions when it must recall data from the (slower) main memory, the CPU is forced to wait instead of getting on with other operations.
A CPU is a computer component which performs the basic arithmetical (such as addition and subtraction), logical, and input/output operations of a computer system. The CPU understands a fixed set of basic instructions, called its instruction set. A single cpu divided into a control unit, arithmetic/logic unit and memory unit. The control unit of a CPU reads and interprets instructions from memory and transforms them into a series of signals to activate other parts of the computer.
We have the microprocessor to thank for all of our consumer electronic devices, because without them, our devices would be much larger. Microprocessors are the feat of generations of research and development. Microprocessors were invented in 1972 by Intel Corporation and have made it so that computers could shrink to the sizes we know today. Before, computers took a room because the transistors or vacuum tubes were individual components. Microprocessors unified the technology on one chip while reducing the costs. Microprocessor technology has been the most important revolution in the computer industry in the past forty years, as microprocessors have allowed our consumer electronics to exist.
The motherboard is the main circuit board of your computer and is also known as the mainboard or logic board. If you ever open your computer, the biggest piece of silicon you see is the motherboard. Attached to the motherboard, you'll find the CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports. It also includes controllers for devices like the hard drive, DVD drive, keyboard, and mouse. Basically, the motherboard is what makes everything in your computer work together.
My interest in Computers dates back to early days of my high school. The field of CS has always fascinated me. The reason for choosing CS stream was not a hasty decision. My interest started developing in the early stage of my life, when I studied about the invention of computers. The transformation from the large size to small palmtops enticed me to know about the factors responsible for making computers, also the electronic gadgets so small. I was quite impressed after seeing a small chip for the first time in my school days, especially after I learnt that it contained more than 1000 transistors, “integrated circuits”.
According to Parsons and Oja (2014), they state that a “microprocessor is an integrated circuit designed to process instructions” (p 67).
In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
