Universal Serial Bus (USB*) is a connectivity specification, currently at version 3, and known as "hi-speed USB". SCSI has been superseded in favour of newer and cheaper technologies such as USB and Firewire. This was used primarily as a connection interface for tape drives and hard disk drives. Pronounced "scuzzy", and stands for "small computer system interface". Parallel ports can still be found in many motherboards today. Similar to the serial port, this technology is slowly being phased out in favour of USB. Parallel ports are used to connect other peripherals such as joysticks, and more commonly, printers.

This trend for USB over PS/2 started in circa 2004. PS/2 based mice and keyboards have now been replaced by USB ports as the popular standard. PS/2 ports (now outdated) were for connecting peripherals such as your keyboard and mouse to the computer. Serial ports can still be found in industrial/commercial applications including computer networking such as Cisco routers like the Cisco 800 Series. By circa 2000, most personal computers stopped relying on serial ports and were replaced by PS/2 and/or USB ports. Ports are used by a motherboard to interface with electronics both inside and outside of the computer.Īn outdated piece of technology, serial ports were most often used to connect the mouse. Other connectors on the motherboard allow communication through cables with various peripheral devices, both inside and outside the computer case.

A PC motherboard may have a series of sockets, allowing daughter boards to be plugged in directly. These boards, together with other plug-in boards without CPUs, may be called "daughter boards." It was called a "mother" board in relation to these. However, other connected printed circuit boards may contain their own microprocessors, either to take some of the load off of the motherboard or to perform specialized tasks better than the general-purpose hardware on the motherboard could. At a minimum it includes one or more Central processing units, and the main processing activity of the computer takes place on it. Introduction to Motherboard Ī motherboard is an electronic circuit board in a computer which interconnects hardware devices attached to it.
