Document Summary
A bus is the highway system for data and it transports data among the processor, memory, and other components. Explain the difference between the isa and the microchannel bus. The isa bus (stands for industry standard architecture) is able to send 16 bits of data at a time and also allowed 9-bit adaptors to be plugged into them while the. Microchannel bus is able to handle twice as much data as the isa bus. Mca did not become the industry standard because it would not accept the older. 8-bit and 16-bit isa expansion cards and pc owners did not like the idea of abandoning perfectly good adaptors. Ibm also originally did not let other companies clone the bus as ibm had permitted earlier bus designs. As there were no other companies supporting mca, it declined and also was countered by ibm competitors in their eisa (extended industry standard architecture).
