System Bus

The type of transfer when processor writes a unit of data to memory is (a)   .

The type of transfer when processor reads data from an I/O device via an I/O module is (a)  

An 8-bit unit of data can be transmitted over (a)   bus lines.

A bus that connects major computer components (processor, memory, I/O) is called a (a)   .

On any bus, the lines can be classified into three functional

groups: _____, _____, _____ lines.

(a)  

The data bus is (a)   , a two-way pathway carrying the data to and from the main memory and the I/O module.

Data lines that provide a path for moving data among system modules are called the (a)   .

(a)   is the number of bits that the bus can carry at a time.

A (a)   wide data bus can carry 16 bits of data simultaneously between the CPU and RAM. 

If the processor wishes to read a word of data from memory, it puts the address of the desired word on the (a)   lines.
