Identify the Names Purposes and Characteristics of Motherboards

The motherboard is the main printed circuit board. It contains the buses, or electrical pathways, found in a computer. These buses allow data to travel between the various components that comprise a computer. A motherboard is also known as the system board, backplane, or main board. Figure 1-4 shows a variety of motherboards.

The motherboard accommodates the central processing unit (CPU), RAM, expansion slots, heat sink/fan assembly, BIOS chip, chip set, and the embedded wires that interconnect the motherboard components. Sockets, internal and external connectors, and various ports are also placed on the motherboard.

Features Motherboard

The form factor of motherboards pertains to the board's size and shape. It also describes the physical layout of the different components and devices on the motherboard. Motherboards have various form factors:

■ Advanced Technology (AT)

■ Advanced Technology Extended (ATX)

■ Smaller footprint than Advanced Technology Extended (Mini-ATX)

■ Smaller footprint than Advanced Technology Extended (Micro-ATX)

■ Low-Profile Extended (LPX)

■ New Low-Profile Extended (NLX)

■ Balanced technology Extended (BTX)

An important set of components on the motherboard is the chip set. The chip set is composed of various integrated circuits attached to the motherboard that control how system hardware interacts with the CPU and motherboard. The CPU is installed into a slot or socket on the motherboard. The socket on the motherboard determines the type of CPU that can be installed.

The chip set of a motherboard allows the CPU to communicate and interact with the computer's other components and to exchange data with system memory (RAM), hard-disk drives, video cards, and other output devices. The chip set establishes how much memory can be added to a motherboard. The chip set also determines the type of connectors on the motherboard.

Most chip sets are divided into two distinct components, northbridge and southbridge. What each component does varies from manufacturer to manufacturer, but in general the north-

bridge controls access to the RAM, video card, and the speeds at which the CPU can communicate with them. The video card is sometimes integrated into the northbridge. The southbridge, in most cases, allows the CPU to communicate with the hard drives, sound card, USB ports, and other input/output (I/O) ports.

            How to identify cpu physically?
            2 months ago
            1. Locate the model number on the processor. This number is usually found on the top or side of the CPU and can be used to identify the manufacturer and model of the processor.
            2. Look for the specifications on the processor. This information can usually be found on the bottom of the CPU or on the side of the processor.
            3. Inspect the processor for size and shape. Different processors come in varying sizes and shapes, so this can help you identify which processor it is.
            4. Look for any labels or symbols to identify the processor. Different processors may have different labels or symbols on them, which can help you identify the processor.
            5. Check the packaging of the processor. If the processor is still in its original packaging, it may have a label or symbol that can help you identify the processor.

                                          • A motherboard is the main printed circuit board (PCB) found in computers and other expandable systems. It holds many of the crucial components of a system, such as the central processing unit (CPU), memory and connectors for input and output devices. It provides the electrical connections by which the other components of the system communicate. Characteristics of a Motherboard:
                                            1. Form Factor: The form factor of a motherboard is one of its most important characteristics. This defines the physical size of the motherboard and the type of case it can fit in.
                                            2. Slots: The slots on a motherboard help to determine what type and how many components the board can support. The two most common slots are PCI (Peripheral Component Interconnect) and ISA (Industry Standard Architecture).
                                            3. Chipset: The chipset of a motherboard is another important factor. It includes the Northbridge and Southbridge chips and drives the overall performance of the board.
                                            4. Expansion Bays: The expansion bays on a motherboard are the locations where additional components and peripherals can be added to the system. Common bays include AGP (Accelerated Graphics Port), IDE (Integrated Drive Electronics) and SATA (Serial ATA).
                                            5. Connectors: The connectors on a motherboard allow for additional devices to be connected to the system. Common connectors include USB (Universal Serial Bus), FireWire (IEEE 1394) and audio ports.

                                                • NLX (New Low Profile Extended) is a CPU socket and motherboard form factor developed by Intel Corporation in 1997. It was designed to replace the ATX form factor by reducing the size of the motherboard and allowing for more efficient airflow through the system. The NLX form factor is smaller than ATX, allowing the motherboard to fit into space-restricted cases, including the so-called mini-tower designs. It is also designed with a low-profile riser card, allowing for easier access and installation of expansion cards. Additionally, NLX provides a more efficient use of internal space for improved airflow, which reduces the chances of component overheating. NLX motherboards are typically used for low-power systems, such as those used in small office and home office environments.
