1. Computer users need different types of computer system. What the user does with the computer dictates the components and peripherals needed. Looking at the computer systems by purpose is a good place to start with design. COMPUTER SYSTEM DESIGN

2. TYPES OF COMPUTER CASES Full Tower Full-tower cases are generally big with a height that is about or more than 30 inches(more than 76 cm) .The number of internal drive bays inside these cases can be between 6 and 10.

3. Take note: * Bay -refers to a space or slot in a computing device where you can insert a specific type of hardware component or peripheral. It is often used to expand or enhance the devices functionally. Bays are commonly found in computers, servers ,and networking equipment.

4. Mid tower Another case that might be a step down, would be classified as a mid-tower case. Mid-tower cases are he most widely used computer cases. Mid-tower cases are about 18 to 24 (45 to 60 cm) inches high and they usually contain 2 to 4 internal drive bays and a similar number of external bays (for CD/DVD readers and similar).

5. Mini tower Mini-tower usually have up to 2 or sometimes 3 internal drive bays . Mini-cases normally stand at a height of 12 to 18 inches (30 to 45 cm). Expandability is a problem with these cases.

6. Slim line cases are simply tower cases turned on their sideways. They can hold a monitor on top of the case. Slim line case

7. Small Form Factor (SFF) Case Small form factor or SFF cases are custom cases that are designed to minimize the spatial volume of a desktop computer. SFFs are available in a variety of sizes and shapes, including shoe boxes, cubes, and book-sized PCs.

8. Mice typically have two buttons, a scroll wheel and a laser sensor. They are used to move the cursor on the screen, select objects and click on buttons. The mouse, which individuals use to direct cursors and make selections on a computer screen, is integral to graphical user interfaces. Mouse case

9. Keyboard A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, navigation keys for moving the text cursor on the screen, function keys and system command keys—such as Esc and Break —for special actions, and often a numeric keypad to facilitate calculations.

10. A typical motherboard contains the CPU, memory, storage, ROM BIOS, Southbridge and Northbridge chipsets, cooling fans, peripheral connector slots, connectors for peripheral devices, the battery backup and the power connector. Motherboard case

11. Chipset A chipset is   a collection of electronic components on a motherboard that manages the flow of data between the CPU, GPU, RAM, storage, and peripherals . It acts as the traffic controller of the motherboard, facilitating communication between all connected components .

12. CPU Principal components of a CPU include the  arithmetic–logic unit  (ALU) that performs  arithmetic  and  logic operations ,  processor registers  that supply  operands  to the ALU and store the results of ALU operations, and a  control unit  that orchestrates the  fetching (from memory) ,  decoding  and  execution (of instructions)  by directing the coordinated operations of the ALU, registers, and other components. 

13. In your own opinion, what is computer system design? Activity: In ¼ sheet of paper. 2 to 3 sentences only.

14. Give at least 5 types of computer case . Ii: ENUMERATION i: identification Refers to a space or slot in a computing device where you can insert a specific type of hardware component or peripheral. 2. Usually have up to 2 or sometimes 3 internal drive bays. 3. Are simply tower cases turned on their sideways. 4. I t the CPU, memory, storage, ROM BIOS, Southbridge and Northbridge chipsets, cooling fans, peripheral connector slots, connectors for peripheral devices, the battery backup and the power connector. 5. is  a collection of electronic components on a motherboard that manages the flow of data between the CPU, GPU, RAM, storage, and peripherals .
