Fifth Generation of Computers

Computers from fourth generation are in use of everyday work. Fifth generation computers are from the future. Actually the computers from fifth generation are already in use under limited exposure and not available for everyone to try as the development process is still ongoing. A few of the characteristics of those fifth generation computers are already in practice or available in the fourth generation computers but those are either not complete nor available for everyone. Following are some of the characteristics of fifth generation computers.

Fourth Generation of Computers (1971 – present)

The computers that we use now-a-days are the computers from fourth generation. From this generation more use of semi-conductors in memory started. Microprocessors has been created with LSI (Large Scale Integration) and VLSI (Very Large Scale Integration). The size and price of computers has both been reduced to significant levels. Followings are some of the characteristics of computers from fourth generation.

First Generation of Computers (1951 – 1959)

Vacuum tubes were used to build computers of first generation. These computers were so large in size because of using thousands of diode, triode, transistors, capacitors etc. and also used to use a lot of electricity. These computers of first generation used to produce a lot of heat, so those were more expensive to support by setting up cooling systems. Maintenance of these huge sized computers were complex and expensive. Following are some of the characteristics of the computers of first generation.

6 Disadvantages of E-commerce

E-commerce or Electronic Commerce is a modern way of business. Transaction in case of buying or selling a product or service through electronic devices and internet connection is E-commerce.

4 fundamental characteristics of Data Communication System

by
Data communication systems enable transfer of data using one of the three transmission modes. Data communication systems has 4 fundamental characteristics; which are delivery, accuracy, timeliness and jitter. Each of these 4 fundamental characteristics has it part in the effectiveness of a data communication system. However, data communication systems work through network systems and there are 3 necessary criteria for an effective and efficient network. Thus a data communication system also depend on the underlying network system’s effectiveness.

Data Communication Network

Data communications are the exchange of data between two devices using one or multiple forms of transmission medium using one of the three transmission modes. That is, data communication is movement of data from one device or end-point to another device or end point through electrical or optical medium. Systems that facilitates this movement of data between devices or end-points are called data communication network. There are 5 components of a data communication network. The devices which are in need to be a part of a data communication network made up of computer hardware and software.
