Describe the VON NEUMANN ARCHITECTURE
Most of present computer designs are based on idea developed by John vonNeumann referred to as the VON NEUMANN ARCHITECTURE. Von Neumann projected that there shall be a unit performing arithmetic and logical operation on data. This unit is known as Arithmetic Logic (ALU). One of the ways to provide the instruction to such computer would be by connecting different logic components in such a way, that they produce desired output for a given combination of inputs. The process of connecting different logic components in specific configuration to achieve desired results is known as Programming. This programming as is achieved by providing instruction within hardware by various connections is called as Hardwired. But this is a very much inflexible process of programming. Let us have a common configuration for logical and arithmetic functions. In such a case there is a requirement of a control signal that directs the ALU to perform a particular arithmetic or logic function on data. Thus, in such a system, by changing control signal the desired function can be performed on data.
