📌Content: The system unit, also known as a “tower” or “chassis,” is the main part of a desktop computer. It includes the motherboard, CPU, RAM, and other components.

DIFFERENT COMPONENTS OF THE SYSTEM UNIT

✳ Motherboard: The motherboard is the core of the system. It really is the PC; everything else is connected to it, and it controls everything in the system.

✳ Processor: The processor is often thought of as the “engine” of the computer. It’s also called the CPU (central processing unit).

✳ Memory (Ram): The system memory is often called RAM (for random access memory). This is the primary memory, which holds all the programs and data the processor is using at a given time.

✳ Case/ chassis: The case is the frame or chassis that houses the motherboard, power supply, disk drives, adapter cards, and any other physical components in the system.

✳ Power supply: The power supply is what feeds electrical power to every single part in the PC.

✳ Floppy drive: The floppy drive is a simple, inexpensive, low-capacity, removable-media, magnetic storage device.

Others are: hard drive, CD-ROMs, keyboard, mouse, video card, monitor and sound card.

The component of the central processing unit (CPU)

✳The two typical components of a CPU include the following: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.

names of the component is:

⚰ ( ALU) arithmetic logic unit.

⚰ ( CU) control unit.

📌Evaluation: At the end of the lesson the teacher will ask the Pupils to:

📌Content:

All primary computer hard drives are found inside a computer case and are attached to the computer motherboard using an ATA, SCSI, or SATA cable.

✳A hard drive can be used to store any data, including pictures, music, videos, text documents, and any files created or downloaded. Also, hard drives store files for the operating system and software programs that run on the computer.

Internal floppy disk drives, although becoming less and less common in modern computers, are normally found at the front of a desktop machine, or, at the side of portable computers such as laptops floppy dish is also known as diskette or simple disk.

📌Content: THE CPU

The central processing unit (CPU), also called a processor, is located inside the computer case on the motherboard. It is sometimes called the brain of the computer, and its job is to carry out commands. Whenever you press a key, click the mouse, or start an application, you’re sending instructions to the CPU.

 

USER OF THE CPU

A central processing unit (CPU) is an important part of every computer. The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body. The CPU is an electronic machine that works on a list of computer things to do, called instructions

All CPU have four main function:

1 stores data,

2 carries out calculations,

3 carries out decisions, and

4 controls the flow of information.

📌Evaluation: at the end of the lesson the teacher will ask the Pupils to:

✳ describe the CPU.

✳ ———– is the brain of the computer.

Names of the component is:

⚰️ ( ALU) arithmetic logic unit.

⚰️ ( CU) control unit.

FUNCTION OF THE (ALU)

An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

📌Building Background /connection to prior knowledge: Pupils has been taught on component of the computer system II

📌Content:

The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. It tells the computer’s memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor.

RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor.
