IBASIC COMPUTER ARCHITECTURE

Addresses, Data, and Bus Control:
The computer system has processor, memory, and I / O devices. I / O is used to connect with the outside world, while memory is internal processor world. The processor is central to this image and is responsible for performing tasks. Computer performance can be well defined with processor and memory only.

I / O will be discussed at later part of the course. Now all computer performance is to process the processor in data, which stays in memory. The state in which the processor works and the memory content data requires a processor for the processor to read that
data from memory is strongly expressed in memory which is dumb. As the postman, who must be given the exact address of the letter, to inform him  where the location is.

Another important point is that if only we you want to re ad the data without writing it, then there has to be a way to do it let us remember that we have a desire to read data and not to write it down. The key points in the discussion above are:
• There should be a way to inform the memory that we want to make learn to work
• There should be a way to inform the memory we want to read exactly what the object is
• There must be a way to transfer that data element away memory in the processor0

A group of bits used by the processor to inform memory about any object to be read or shared collectively known as an address bus. Another important bus called data bus is used to transport data from memory to processor in read activity and from processor to file
memory in writing operations. The third group contains the mixture independent lines used for control purposes. For example, one bus line is used to inform memory about a learning activity or write performance.

These lines are known collectively as a control bus. These three buses have the eyes, nose and ears of the processor. It uses in a coordinated way to make the work visible. Or the program builder specifies meaningful performance, but achieves it the processor requires interaction with other units and parameters. And that collaboration is made available using three buses.

This is very basic computer description and can be extended to the same line to I / O but we leave it out for the convenience of the moment.The bus address is incomprehensible and the address is always up processor in memory. This is because memory is a dumb tool and cannot guess which processor at some point in time. Data goes from both, the processor to the memory and the memory to the processor, therefore the data bus is bidirectional. The control bus is special and sophisticated, because the different lines it makes behave differently.
