Q6.What is the bus width of EISA bus?

1. 8-bit
2. 16-bit
3. 32-bit
4. 64-bit

Correct Answer: C.

 Explanation: Given below are important bus types and their characteristics:
Bus Type---Data bus width---Speed------Bandwidth--Comments
8-bit ISA------8-bit----- ----8.3MHz-----7.9MBPS----Not used in modern computers
ISA----------16-bit----------8.3MHz-----15.9MBPS---In use, use jumpers to configure
EISA---------32-bit----------8.3MHz-----31.8MBPS---Backward compatible with ISA, uses software/ jumpers for configuration
VESA or VL bus---32-bit------33MHz------127.2MBPS--Backward compatible with ISA cards
PCI-------------- 32-bit------33MHz------127.2MBPS--Supports Plug and Play
64-bit PCI-------- 64-bit------66MHz------508.6MBPS--Supports Plug and Play
PCMCIA-----------32-bit------33MHz-------------------Used in laptops, also know as PC card
AGP------------   32-bit----Speed of Processor----------Used in video cards
