COMPUTER ORGANIZATION

Chapter 4:-

1. von Newmann computer has these components

a) CPU made of ALU (Arithmatic Logic Unit) and a control unit

b) Primary/executable memory

c) Collection of I/O

d) Buses to interconnect the other components.

2. Microprocessors use SDL ( Synchonous Digital Logic ), having a basic clock cycle that defines when the operations are performed at transistor-level circuitry.

3. Some terminology to understand:-

SCSI (Small Computer Serial Interface) => Device manufactured by one vendor can be connected to a controller manufactured by another.

DMA (Direct Access Memory) => Able to read/write information directly from / to primary memory with no CPU intervention.

Memory Mapped I/O => devices are assiciated with logical primary memory addresses rather than having specialized device addresses.
