Hardware Components
The Computer System Consists of:
Input, Output and CPU units
Explain in details what do we mean by Bus
•It is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
•Computer systems generally consist of three main parts: the central processing unit (CPU) that processes data, memory that holds the programs and data to be processed, and I/O (input/output) devices as peripherals that communicate with the outside world.
Define the following Acronym
1. DIMM
2. RIMM

What is BIOS and what are its main functions
Basic Input/ Output System (BIOS) chip contains the BIOS systems software that boots the system
Allows the OS to interact with certain hardware in the computer
Performs power-on self-test (POST)
Discuss different types of Communication Connections
Ethernet
•To connect to a LAN or a WLAN
• The wired connection presents itself as an RJ45 port.
Bluetooth
•To connect to other Bluetooth devices over short distances, thus joining or creating a personal area network (PAN).
differentiate between AT and ATX power supply tools
ATX
1. All Pentium II and later based systems
2. The on-off power control circuit boards is built into the motherboard
3. This style power supplies connect to the motherboard through a single 20-pin connector
AT
1. Older Pentium-based computers and all 486-based and earlier PCs
2. On AT-style PCs, it comes from power supply.
3. This style power supplies connect to the motherboard through a pair of six-wire connectors.

Name the two types of system boards with at least two differences between them
Non-integrated system board
1. Each major assembly is installed in the computer as an expansion card.
2.The major assemblies are video circuitry, disk controllers and accessories
Integrated system board
1. Most of the components are integrated into the motherboard circuitry.
2. Simple and cheaper to produce, but expensive to repair.
3. When one component breaks, whole motherboard must be replaced.
Explain in details how BIOS work
BIOS performs the POST, which initializes and tests your computer's hardware. Then it locates and runs your boot loader, or loads your operating system directly. The BIOS also provides a simple interface for configuring your computer's hardware. When you start your computer, you will often see a message like "Press F2 for setup." This setup is your BIOS configuration interface. For more information about configuring your BIOS, see our guide to configuring your BIOS

List the characteristics of each of the following peripheral devices:
1. Parallel
2. Serial
3.USB
4. IEEE 1394 (FireWire)
5. PS/2
Parallel
• Transfers data 8 bits at a time over eight separate transmit wires (one bit per wire)
•Use a DB-25 female connector
Serial Port
• built into the mother board,
• Serial connectors generally have 9 or 25 pins
• Bits of data are sent one after another
Universal Serial Bus (USB)
•Used to connect a wide variety of peripherals to computers, including keyboards, mice, digital cameras, printers and scanners.
•Connectors are identical
•Plug and Play-just plug in the peripheral
IEEE 1394 (FireWire)
•High data transfer rate
•Used more and more as a universal, high-speed data interface for hard drives, optical drivers, and digital video editing equipment
PS/2
•Used for mice and keyboards.
•It is the same connector for the cables from both items: a male mini-DIN 6 connector.
Mostly for video card
this Expansion Slot does the following:
•Direct connection between the video circuitry and the PC’s memory.
•Usually brown
•Located right next to the PCI slots on motherboard
•Slightly shorter than the PCI slots
