Present computers

The most unusual characteristic of Computer Modern, however, is the fact that it is a complete type family designed with the metafont system.

Gifting someone a computer is something that can burn a hole in one’s pocket but it can surely be the ideal gift these holidays.Depending with who you work and what relationship you share with them, gifting them a game such as a PlayStation or Xbox this season will be perfect. Tell them that you want to spend time with them and have a great year ahead.Picking the inventions that changed the way people live is often a matter of opinion. Some people could care less about whether or not they have a cell phone or GPS; on the other hand, it would be hard to find anyone who doesn’t think electricity changed life. Here are the top ten most life changing inventions in the modern world that have altered the way people think and do things on a daily basis.

FUTURE COMPUTERS

Nanoplasmonic devices key components are tiny nanoscale metal structures more then 100 times smaller than the width of a human hair  that guide and direct light.
The structures have been tailor-made to interact with light in an unusual and highly controlled way.This means they could one day be used to build new kinds of supehigh-speed ‘optical computers  so named because they would process information using light signals, instead of the electric currents used by today’s computers.
This is increasing our brain power, just as steam engines increased our muscle power. As computers become more powerful they will grow more intelligent There seems no reason why machines should not become more intelligent than people in the future. Computers will start to design and build other computers.
Recent innovations such as the iPad provide an exciting glimpse into the future of computers. Before looking forward toward future computer trends, let's take a quick look back to gain a better appreciation of the evolution thus far.
 Do you remember when the first primitive computing machines occupied entire buildings? The massive machines from the mid 20th century consisted of row upon row of vacuum.

Past Computers




 

Computers were designed to directly connect to a television for audio/video output. One of the trends which was relatively short-lived was to make video game systems which could be upgraded into computer systems. Another of the trends which extended from the late '70s through the mid '80s was that a large number of computer owners learned the basic programming language (it was built-in on many computers) and could create their own programs; many computer manuals (Commodore, T/S 1000, 800) provided detailed information on learning.

A new Timeline of the History of Computers and Related Technologies has been added. This site was designed to be used by students assigned topics about the history of computers and computing. Original articles are footnoted and related links are included. One important purpose of this Web page, is to debunk myths some people create, such as we have computers because of the military (Not true). We have computers because man wanted to quantify as early as the ancient Chinese Dynasties, when they created the abacus and used it for calculating, and adding and subtracting in particular... Babbage and Lovelace were "programming" machines as early as the 1800's before any military computer in this country. 1801 was the creation of the Jacquard loom which used "punch cards". Cathode Ray Tubes (CRTs) have been around since 1885 and the US gov't first used a computer in the 1950's.

The home computers between 1977 and about 1990 were different from today's uniform and predictable machines. During this time it made economic sense for manufacturers to make microcomputers aimed at the home user. By simplifying the machines, and making use of household items such as television sets and cassette recorders instead of dedicated computer peripherals, the home computer allowed the consumer to own a computer at a fraction of the price of computers oriented to small business. Today, the price of microcomputers has dropped to the point where there's no advantage to building a separate, incompatible series just for home users.
