1. CPU (Central Processing Unit) chip

CPU is the electronic circuitry in a computer that Distributor Motherboard medan executes instructions that make up a program. It is also known as a central processor or the main processor. The CPU executes the basic logic, arithmetic, controlling as well as input/hasil (I/O) operations specified by the instructions in the desktop programs.

2. RAM (Random Access Memory) slots

RAM is a kind of computer memory that can be read and written. It is mainly used to save data and machine code. A RAM device permits data to be read or written in nearly the same amount of time no matter where the data’s physical location is in the memory. Compared to the direct-access storage devices like hard drives, CD/DVD and magnetic tapes, RAM media is much faster for data reading and writing.

tiga. Southbridge/northbridge

They are the Jual Motherboard two chips in the core logic chipset on the motherboard. Typically, the southbridge implements the slower capabilities of the motherboard in a northbridge/southbridge chipset computer architecture.

The northbridge, also known as host bridge or Memory Controller Hub, is connected directly to the CPU via the front-side bus (FSB). It is responsible for tasks requiring the highest performance. Together with the southbridge, they manage communications between the CPU and other motherboard components.

4. BIOS (Basic Input/Output System)

BIOS, also called system BIOS, PC BIOS or ROM BIOS, is firmware that is used to perform hardware initialization during the booting process; and to provide runtime services for operating system and programs. The BIOS firmware is the first software to run when powered on; it is re-installed on a PC’s system board.

5. I/O port

Input/hasil ports are the connections between the CPU and peripheral devices on a motherboard. There are two complementary methods to perform input and hasil processes: memory-mapped I/O (MMIO) and port-mapped I/O (PMIO). Alternatively, you can use dedicated I/O processors, called channels on mainframe computers, which execute their own instructions. 

6. USB (Universal Serial Bus)

USB is an industry standard that creates specifications for connectors, cables and protocols for connection; power supply (interfacing) and communication among computers, computer peripherals as well as other desktops. There are a great many USB hardware including several different connectors, of which USB-C is the latest kind.  

7. CPU slot

A CPU slot, also called a CPU socket or Processor socket, contains one or more mechanical components that provide mechanical and electrical connections between the PCB and a microprocessor (CPU). Therefore, you can install a CPU on a motherboard without soldering.

8. PCI (Peripheral Component Interconnect) slot

Peripheral Component Interconnect is a Supplier Motherboard medan local computer bus for connecting hardware to a computer. It supports all the functions of a processor bus. PCI is usually Toko Motherboard medan been called Conventional PCI to distinguish it from its successor PCI Express (PCIe, PCI-e or PCI-E).

PCI Express is a high-speed serial computer expansion bus standard designed to replace the older PCI, PCI-X and AGP bus standard. It is a general-use motherboard interface for the graphics card, SSDs, hard drives, Wi-Fi as well as Ethernet hardware connections.

This post tells you the differences between PCI and PCIe. It also shows you how to distinguish them.

9. AGP (Accelerated Graphics Port) slot

AGP was designed as a high-speed point-to-point channel for connecting a video card (graphics card) to a computer system. Primarily, it was used to assist in the acceleration of 3D computer graphics. AGP is originally designed to be a descendant of the PCI series of connections for video cards. Yet, it was replaced by the PCIe slots.

10. ISA (Industry Standard Architecture) slot

ISA is the 16-bit internal bus of IMB PC/AT and similar computers that are based on Intel 80286 and its immediate successors during the 1980s. It was backward compatible with the 8-bit bus of the 8088-based IBM PC largely.

There once was an attempt to extend ISA into a 32-bit bus, called Extended Industry Standard Architecture (EISA). The attempt wasn’t very successful and the EISA was largely replaced by the later VESA Local Bus and the PCI bus.

11. Parallel port

A parallel port is a kind of interface for attaching peripherals on desktops. The name of this kind of port is derived from the way the data is sent. That is, the parallel ports send multiple bits of data at the same time. Serial interfaces, on the contrary, send bits one data at once. To achieve parallel data transfer, there are multiple data lines in the parallel port cables. The parallel port cable is larger than the cable of a contemporary serial port, which only has one data line within. 

12. FDC (Floppy-Disk Controller)

FDC is a special-purpose chip and associated disk controller circuitry. It controls and directs reading from and writing to a computer’s floppy disk drive (FDD).

13. IDE (Integrated Drive Electronics) controller

The devices used for connecting IDE, Ethernet, FireWire, USB and other systems can be called host adapter. So, the IDE controller refers to the host adapter. A host adapter, also called a host controller or a host bus adapter (HBA), connects a computer (acting as the host system) to other network and storage devices.

Tip: Host adapter is usually used to indicate devices connecting SCSI, Fibre Channel and SATA devices.

Do you think your IDE hard drive is too old and outdated? How to upgrade IDE to SATA HDD or SSD? There is a step-by-step tutorial to help you.

14. CMOS (Complementary Metal-oxide-semiconductor) battery

CMOS battery, also called memory battery, clock battery or real-time clock (RTC), is generally a CR2032 lithium coin cell. The lifespan of the CMOS battery is estimated to be three years when the power supply unit (PSU) is unplugged or switch off.  

15. Power supply connector

A power supply provides the necessary electrical power to let the computer to work. It takes standard 110-Volt AC (Alternative Current) power to DC (Direct Current) power of 12 Volt, 5 Volt, 3.tiga Volt, etc.

16. Mouse and keyboard ports

All computers have a keyboard port connected directly to the motherboard. There are two types of connectors. The oldest one is a special DIN (Deutsches Institut für Normung) connector while the newest one is the kecil DIN PS/2-style connector. Many PCs use the PS/dua-style connectors for both keyboard and mouse; and the connectors are marked clearly for different usage.  

17. DIP (Dual In-line Package) switch

A DIP switch is a manual electric switch packaged with others in a standard dual in-line package. The term may refer to an individual switch or the whole unit. The DIP switch is designed to be used on a printed circuit board (motherboard) together with other electronic motherboard components. It is usually used to customize the behavior of an electronic device for specific situations.

Alternatively referred to as the mb, maDistributor Motherboard medan inboard, mboard, mobo, mobd, backplane board, base board, main circuit board, planar board, system board, or a logic board on Apple computers. The motherboard is a printed circuit board and foundation of a computer that is the biggest board in a computer chassis. It allocates power and allows communication to and between the CPU, RAM, and all other computer hardware components.Motherboard overview

A motherboard provides connectivity between the hardware components of a computer, like the processor (CPU), memory (RAM), hard drive, and video card. There are multiple types of motherboards, designed to fit different types and sizes of computers.

Each type of motherboard is designed to work with specific types of processors and memory, so they don’t work with every processor and type of memory. However, hard drives are mostly universal and work with the majority of motherboards, regardless of the type or brand.

Below is a picture of the ASUS P5AD2-E motherboard with labels next to each of its major components. Clicking the image directs you to a larger and more detailed version.

Where is the motherboard located?

A computer motherboard is located inside the computer case and is where most of the parts and computer peripherals connect. With tower computers, the motherboard is on the left or right side of the tower and is the biggest circuit board.Motherboard components

Below are links to pages with more details for each of the motherboard components mentioned in the previous section. The links are listed in clockwise order starting from the top-left corner of the image.

As computers advanced, so have motherboards. Below is a list of the various motherboard form factors and additional information about each, including ATX, which is the most common.ATATXBaby ATBTXDTXLPXFull ATFull ATXmicroATXNLXHow many connections, ports, or slots are on a motherboard?

There’s no set standard to how many connections, ports, or expansion slots are on a motherboard. The best method of determining how many connections, ports, or slots are available for your motherboard is to look up the specifications contained in its documentation. If you’ve lost or discarded your motherboard’s documentation, you can often download a free PDF version from the manufacturer’s website.How do I find what computer motherboard I have?Why are the slots and connections different colors?

The slots, ports, and connections on a motherboard may be color-coded to help identify the type of slot, port, or connector. For example, with our motherboard picture, the IDE connectors are different colors to help identify the primary and secondary connectors. When the memory slots are different colors, it indicates the memory slots are dual-channel, and pairs of memory should be installed on the same channel (color). For example, in our picture, the yellow memory slots are Channel A, and Channel B are the black slots. If you were only installing two memory sticks, you’d want to install both of them in Channel A (yellow slots) for optimal performance.

See our color-coded laman for information and examples of the color of the ports on the back of the motherboard.How does a motherboard connect to a computer case?

A computer motherboard connects to a desktop computer case using standouts. Once the motherboard is attached to the case, all other devices connect to the motherboard itself or an expansion card.How to install a computer motherboard.What was the first motherboard?

The first motherboard is considered to be one used in the IBM Personal Computer, released in 1981. At the time, IBM called it a “planar” instead of a motherboard. The IBM Personal Computer and the motherboard inside it would set the standard for IBM-compatible computer hardware going forward.Since there is a motherboard, is there a fatherboard?

No, there is no such thing as a fatherboard when referring to a computer. However, there is such a thing as a daughterboard.Where did the motherboard get its name?

The daughterboards we mentioned in the previous section are circuit boards that all plug into one larger central circuit board; a motherboard. The smaller boards can be thought of as the main board’s “children,” hence the name motherboard.Are Dell, HP, and other OEM motherboards different?

Yes, OEM motherboards from manufacturers like Dell and HP are slightly different than other motherboards you’d find from a retailer. An OEM designs their motherboard for their needs for each model of computer. Some OEMs may even make drastic changes that go beyond the typical motherboard form factor. However, although an OEM motherboard may have it’s differences, visually they often look very similar. Also, if there hasn’t been too many changes, it may be possible to replace the OEM motherboard with a retail motherboard. For OEM computers with lots of differences that need replaced, you’ll need a replacement from the OEM or through a third-party that sells parts from used computers.Is there a motherboard in a laptop, smartphone, and tablet?

Yes, although the board is often referred to as a “logic board” and not a motherboard. The logic board is very similar to a motherboard and operates the same way. However, because of size requirements with most logic boards, components like the processor and RAM (in tablets and smartphones) are soldered onto the board. Also, because many of these devices have no upgrade options, there are no slots or sockets like a traditional computer motherboard.
