Computer Architecture and Organization?

Image
Computer Architecture & Organization Architecture is those attributes visible to the programmer Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques. Organization is how features are implemented Control signals, interfaces, memory technology.   An open architecture allows the system to be connected easily to devices and programs made by other manufacturers. Open architectures use off-the-shelf components and conform to approved standards. A system with a closed architecture, on the other hand, is one whose design is proprietary , making it difficult to connect the system to other systems.  

Operating System.....

What is an operating system? An operating system is a layer of software which takes care of technical aspects of a computer's operation.   It shields the user of the machine from the low-level details of the machine's operation and provides frequently needed facilities.  Operating systems may be classified by both how many tasks they can perform `simultaneously' and by how many users can be using the system `simultaneously'. That is:   single-user   or   multi-user   and   single-task   or   multi-tasking . A multi-user system must clearly be multi-tasking. The table below shows some examples.
