In computing, an expansion card (also called an expansion board, adapter card, peripheral card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system. Sometimes ...
The CPU card contains the PC functionality and communicates with the other cards plugged into the backplane through a computer bus. CPU cards may also be called expansion cards or expansion boards, and offer a variety of embedded applications from modems and wireless networking to graphics and video controllers to RAID controllers.
A riser card is a printed circuit board that gives a computer motherboard the option for additional expansion cards to be added to the computer. [1]
In addition, there are bus expansion cables which will extend a computer bus to an external backplane, usually located in an enclosure, to provide more or different slots than the host computer provides. These cable sets have a transmitter board located in the computer, an expansion board in the remote backplane, and a cable between the two.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
Famous 1980s expanded memory boards were AST RAMpage, IBM PS/2 80286 Memory Expansion Option, AT&T Expanded Memory Adapter and the Intel Above Board. Given the price of RAM during the period, up to several hundred dollars per MiB, and the quality and reputation of the above brand names, an expanded memory board was very expensive.
The Florida Board of Education on Wednesday approved a ban on classroom instruction about sexual orientation and gender identity in all grades, expanding the law critics call “Don't Say Gay ...
microATX boards often use the same chipsets as full-size ATX boards, allowing them to use many of the same components. However, since microATX cases are typically much smaller than ATX cases, they usually have fewer expansion slots. [citation needed]
