Definition - What does Internal Bus mean?
An internal bus is a type of data bus that only operates internally in a computer or system. It carries data and operations as a standard bus; however, it is only used for connecting and interacting with internal computer components.
An internal bus is also known as an internal data bus, frontside bus (FSB) and local bus.
Techopedia explains Internal Bus
An internal data bus enables the following:
- Connection of key components installed in or local to a computer
- Connection of the motheroard with a processor, memory, storage and other components
An internal bus can carry data, memory addresses, control information and any other internal communications or processes. Because an internal bus is internal to the system and closely installed, it enables faster data transfer than an external bus.
Commonly used internal bus examples include a memory bus, system bus and Accelerated Graphics Port (AGP) bus.
