This document discusses computer interconnection structures and components. It summarizes that a computer consists of modules like the CPU, memory, and I/O that communicate with each other. The connections between these modules is called the interconnection structure. The design of this structure depends on the exchanges needed between the modules. It then provides more details on the memory module, I/O module, and CPU and how they are connected and transfer data and instructions through the bus interconnection.

2.  A Computer consists of a set of
components(CPU , Memory , I/O Module)
that are communicate with each other.
 The collection of paths
connecting the various module is called
interconnection structure.
 The design of structure will
depend on the exchange that must be
made between modules

8. Bus interconnection is
important component of
computer: architecture. It is a
communication channel. It
connects various components of
computer to communicate with
each other.
