80186 Microprocessors: Introduction and Architecture

Hello friends, today we are going to discuss the 80186 microprocessor with integrated peripherals. The Intel 80186 is an improved version of the 8086 microprocessor. 80186 is a 16-bit microprocessor with a 16-bit data bus and a 20-bit address bus. It has a programmable peripheral device integrated into the same package. The instruction set of the 80186 is a superset of the instruction set of the 8086. The term super-set means that all of the 8086 instructions will execute properly on an 80186, but the 80186 has a few additional instructions. The following figure shows the block diagram and pin diagram of 80186. The CPU is divided into seven independent functional parts. 80186 internal block diagram  80186 68-pins pin diagram  Functional parts of 80186 Microprocessor The Bus Interface Unit (BIU) Execution Unit (EU) Clock Generator Programmable interrupt controller Programmable Chip Select Unit (CSU) Programmable DMA Unit Programmable counter/timers The Bus Interface Unit ...

Computer Networks Application

There are two types of network applications.
1. Business Network application
2. personal Network application
A brief applications of computer networks are as follows.v Business Network Application
§  Resource sharing:
The goal is to make all programs, equipments and especially data available to anyone on the network without regard to the physical location of the resource and the user
§  High reliability:
All files could be duplicated on two or three machines, so if one of them is unavailable due to hardware failure, the other copies could be used.
In addition, the presence of multiple CPUs, if one goes down, the others may be able to take over its work.
§  Saving Money:
Personal computers have a much better price/performance ratio than large mainframe room-sized computers. (Mainframe computers are ten times faster than personal computers, but their cost is thousand times more)
§  High communication medium:
A computer network can provide a powerful communication medium among widely separated employees, through e-mails, conferencing etc.
v Personal Network Applications:
§  Access to remote information:
Access to remote information will come in many forms like different bills, manage their bank accounts and handle their investments electronically. home shopping is also becoming popular. News papers will go on-line. Access to information systems like the current world wide web, which contains information about the arts, business, cooking, government, health, history, hobbies, science, sports, travel and many more….

§  Person to person communication:
E-mails is already widely used by millions of people with contain audio, video as well as text. This technology makes it possible to have virtual meetings, called videoconference, among far-flung people.

§  Interactive entertainment:
Video on demand, movie or television program have it displayed on your screen instantly. Live TV may also become interactive, with the audience participating in quiz shows. Also we have  real time simulation games, like hide-and-seek in a virtual dungeon.
