Buses play an essential role inmodern computersby connecting all computer parts together with an efficient communication method. As discussed above, they enable the subsystems -such asI/O ports,RAMandROM-to interact with one another by providing fast data transfer rates with fewer bottlenecks than t...

buses (also called local buses) connect components inside the computer, while external buses connect the ports used for attaching peripherals. For example, a computer's internal memory bus connects the RAM slots to the memory controller, while the externalUSBbus connects USB ports to theI/O...
A voice bus on a computer backplane provides point-to-point connection between a plurality of slots on the backplane to a particular slot. Connection from the plurality of slots is provided by third connectors which lie between first and second connectors defining the slots. Connection to the par...
An interactive computer terminal system includes a CPU 4A, a direct memory access (DMA) controller, a RAM 8A, terminal display units 16-1A to 16-32A and various other units all coupled to a system bus 2A. The CPU 4A includes bus arbitration logic which assigns time slots on the system ...
which is why computers have so many slots on the bus. But through the 1980s and 1990s, new systems like SCSI and IDE were introduced to serve this need, leaving most slots in modern systems empty. Today there are likely to be about five different buses in the typical machine, supporting...
This addressing scheme yields the Ultra 2 addresses shown inTable A-1. Other implementations might use a different number of address bits. The Ultra 2 has seven SBus slots, four of which are physical. Slots 0 through 3 are available for SBus cards. Slots 4-12 are reserved. The slots are...
Address Bus:The address bus carriesinformationabout the location of data in memory. Control Bus: The control bus carries the control signals that make sure everything is flowing smoothly from place to place. Expansion Bus:If your computer hasexpansion slots,there’s anexpansion bus.Messages andinf...
a motherboard has several expansion bus slots allowing components such as a video card, adisk controller, a modern, or a parallel-port card to communicate with the computer. There are three common types of busses: industry standard architecture (ISA),peripheral component interconnect(PCI) local ...
) slots for expansion cards such as graphics cards and sound cards, central processing unit (CPU) fan headers for connecting cooling fans, and random-access memory (RAM) slots for memory modules. These connectors play essential roles in the overall functionality and expandability of your computer....
