A motherboard connector or a header is a part of the motherboard assembly in which several or all of the components of a computer are soldered or otherwise fastened together. The term was coined by IBM’s engineers during the development of the IBM System/360 mainframe computer line in the 1960s, where they designed it as a convenient place to hold circuit boards (hence “header”).
The motherboard is a printed circuit board that provides mechanical support for the CPU and other electronic components, such as video cards, sound cards, and other cards. The motherboard is the foundation of the computer and holds everything in place. It is connected to the system’s main power supply and, if the motherboard is connected to a display, the monitor. The motherboard also provides the means for the computer to communicate with the outside world. The motherboard has slots for memory modules and PCI expansion cards, and for most computers it also has expansion slots for other devices such as sound cards and video cards.
The motherboard itself is usually a rectangular or square printed circuit board. The most common form is a rectangular board, although the board can also be a square or circular. The edges of the board are populated with various connectors, usually located at the front of the board. A typical motherboard has a socket for the CPU and sockets for video cards and other expansion cards. There may also be a socket for a floppy disk drive, a socket for a CD-ROM drive, a socket for a parallel port, and/or a socket for a serial port.
Recipe of Motherboard
A motherboard is made of rigid material such as FR4 or FR5, with traces and components printed on it. The traces are generally copper or aluminum, although other materials can be used. Components are soldered or otherwise attached to the traces. The components include sockets, resistors, capacitors, transistors, diodes, and many other devices. The motherboard may have one or more chips on it, such as a processor or memory controller. The chips may be integrated circuits, but are often soldered to the motherboard with a chip carrier.
PCI is an expansion bus standard for personal computers and other devices that uses a shared memory and I/O address space. The standard was designed to be used with plug-in expansion cards, such as video cards, sound cards, and network cards.
The PCI bus is a computer bus designed to provide a high-speed interconnect between devices. The standard was developed by the PCI Special Interest Group (PCI-SIG), a consortium of leading computer hardware manufacturers, and is widely used in personal computers and other devices.
The PCI bus has a high data rate and is widely used in computer systems. The PCI bus provides a way for devices to communicate with each other by transferring data in blocks called frames. The frames are transferred between devices in a stream of bits. A typical PCI bus has a data rate of 33,600 bits per second (33.6 megabits per second).
The PCI bus is a 32-bit bus. The PCI bus has a 32-bit address bus, a 32-bit data bus, and a 16-bit command bus. The PCI bus has a limited address space, and devices must have an address that falls within this address space.
