• Case and Power Supply

• Motherboard

• Central Processing Unit (CPU)

• Random Access Memory (RAM)

• Internal Storage Devices (HDD, SSD)

Poll

Have you ever built a computer before?

• Yes

• No

Computer Case

Computer Case

The computer case houses the internal computer components such as the power supply, motherboard, cpu, ram and hard drives.

Computer Case

Computer cases come in different form factors (sizes and layouts) such as horizontal cases, vertical towers, laptops and all-in-one varieties.

Multiple Select

Which of the below are types of computer case form factors?

• All-in-one

• Vertical Tower

• Open Tower

• Horizontal Case

Power Supply

Power Supply

Power supplies convert AC power into the lower voltage DC power that is used by the internal components of the computer.

Multiple Choice

The computer power supply converts what to what?

• AC to DC

• DC to AC

• BC to AD

Motherboard

Motherboard

The motherboard is the backbone of the computer and all internal components are connected together through the printed circuitry on the motherboard

Multiple Choice

What device connects internal components together?

• Computer Case

• Power Supply

• Motherboard

• Fatherboard

Central Processing Unit (CPU)

Central Processing Unit (CPU)

The CPU is also known as the brain of the computer is responsible for executing the computers commands and code.

Random Access Memory (RAM)

Random Access Memory (RAM)

RAM stores temporary data for programs accessed by the computer. RAM is volatile and is deleted when the computer is turned off.

Random Access Memory (RAM)

Adding more RAM to a computer can enhance performance. Though the maximum amount of RAM usable is limited by the motherboard.

Multiple Choice

Does RAM store data through a computer power cycle?

• Yes

• No

Internal Storage Devices (HDD, SSD)

Internal Storage Devices

Internal storage devices are used for long term storage of personal data, system files, and software used on and by the computer.

Internal Storage - Hard Disk Drive

Hard Disk Drive (HDD) is an internal storage device that uses mechanical parts and magnets to read/write data to the drives storage platter.

Internal Storage - Solid State Drive

Solid State Drives (SSD) use integrated circuits and flash memory to store the data required and are typically faster then the older HDDs they replace.

Multiple Choice

Which of these is the faster internal storage device?

• Hard Disk Drive

• Solid State Drive

• Soft Disk Drive

• Compact Disk Drive

Multiple Choice

Which of these use magnets to read data from the drive?

• Hard Disk Drive

• Solid State Drive

• Soft Disk Drive

• Compact Disk Drive
