PART II: INTERNAL COMPONENTS

---

In this section, students explore the internal components of a computer system. Topics include microprocessors, motherboards, chipsets, and controllers. Students learn about the role of each element in the system architecture and how they interact to facilitate data processing and communication.

MICROPROCESSORS:

Students explore the heart of the computer system – the microprocessor. They learn about different types of processors, their specifications, and performance characteristics. Topics include CPU architecture, instruction set, clock speed, and multi-core processing.

MOTHERBOARDS:

The motherboard serves as the central hub that connects all internal components of a computer system. Students study motherboard form factors, layouts, and components such as CPU sockets, expansion slots, and memory slots. They also learn about BIOS (Basic Input/Output System) and the boot process.

COMPUTER MEMORY:

Memory is critical in storing and accessing data in a computer system. Students learn about different types of computer memory, including RAM (Random Access Memory) and ROM (Read-Only Memory). They explore memory modules, addressing schemes, and memory management techniques.

HARD DISKS AND FLOPPY DISKS:

Storage devices are essential for storing data and programs. Students study hard disk drives (HDDs), solid-state drives (SSDs), and floppy drives. They learn about disk geometry, file systems, disk partitions and management utilities.

CD-ROMS AND DVDS:

Optical drives, such as CD-ROMs and DVDs, read and write optical discs. Students explore optical disc formats, storage capacities, and data retrieval methods. They also learn about optical disc-burning software and techniques.

EXPANSION CARDS:

Expansion cards enhance the functionality of a computer system by adding specialized features or connectivity options. Students study different types of expansion cards, including video cards, sound cards, network interface cards (NICs), and expansion slots such as PCI and PCIe.

VIDEO CARDS:

The video card, or graphics processing unit (GPU), renders images and videos on the computer monitor. Students learn about GPU architecture, video memory, display resolutions, and graphics rendering techniques.

SYSTEM RESOURCES:

Students explore system resources such as IRQs (Interrupt Requests), DMA (Direct Memory Access) channels, and I/O (Input/Output) addresses. They learn how the operating system allocates and manages system resources to facilitate communication between hardware components.

POWER SUPPLY AND ELECTRICAL ISSUES:

The power supply unit (PSU) provides electrical power to the computer components. Students study PSU specifications, voltages, currents, and power connectors. They also learn about common electrical issues such as voltage fluctuations, power surges, and grounding problems.
