Von Neumann Architecture :
Von Neumann Architecture The von Neumann architecture is a design model for a stored program digital computer that uses a central processing unit and a single separate storage structure called memory to hold both instructions and data. It is named after the mathematician and early computer scientist John von Neumann.
Computers based on this design :
Computers based on this design A stored-program digital computer is one that keeps its programmed instructions, as well as its data, in read write, random access memory (RAM). Stored program computers were an advancement over the program controlled computers of the 1940s, such as the Colossus and the ENIAC which were programmed by setting switches and inserting patch leads to route data and to control signals between various functional units.
The Colossus Mark 2 Computer.
Computers Today :
Computers Today Computers today are designed on this architecture based that all computer must have an input and output.
They have been scaled down to be used as a common tool these days in everyday life. As we have seen that the Colossus and ENIAC are not portable .
The modern computer is not much different to the very first computer designed, all that has changed is that modern computer have become more powerful and compact. This can be seen throughout out all electronic devices today.
Southbridge :
Southbridge The Southbridge is one of the two chips in the core logic chipset on a PC motherboard the other being the northbridge. The southbridge typically implements the "slower" capabilities of the motherboard in a northbridge southbridge chipset computer architecture. In Intel chipset systems the southbridge is named Input/Output Controller Hub (ICH).
Northbridge :
Northbridge The northbridge is one of the two chips in the core logic chipset on a PC motherboard, the other being the southbridge. In Intel chipset systems it is named memory controller hub (MCH) or integrated memory controller (IMCH) if equipped with an integrated VGA.
