Advantages of Computer Technology in spreading information: The sizes of computers have changed considerably over the years, like the technology. Earlier computers were big and used to consume the power of nearly a hundred modern personal computers. But, nowadays they are available in small sizes, so much so that some even fit into wristwatches and can be powered by simple watch batteries. The portable version, the laptop is also very popular. But, by far the most common computer in use today is the embedded computer. These are small and simple electronic devices that often control other devices. They are commonly observed in fighter aircrafts and industrial robots and even in children’s toys. The greatest advantage of the computer technology is its power to store and execute programs, thereby making it extremely versatile. It facilitates self-paced learning and enables people to learn, as per their grasping power, with immediate reinforcement and feedback.

Computer technology offers its main advantage in the form of multimedia operations, with integrated graphic, print, audio and video capacity. It acts as an interactive medium for users, as microcomputer systems incorporate several software packages that are highly flexible and maximize learner control. Computer technology increases access and links people across the globe, thereby empowering them with adequate and specific information. In addition, it helps to boost the quality of education in schools and colleges, via the Internet. This technology is beneficial to almost every field of study, whether it is science, information technology, creative article writing or introduction of the latest course material in a class. The Internet is a worldwide accessible network of interconnected computer networks that transmit data by packet switching, using the standard Internet Protocol.

Disadvantages of Computer Technology: Besides these advantages, computer technology also has several disadvantages. The popular notion about this technology is that it has initiated significant improvement in productivity, but it debatable whether it actually translates into an effective impact on the overall productivity, always. One of the major disadvantages of the computer technology is that it increases an individual’s dependency on the machine. It often has an addictive effect on children and they tend to spend most of their time playing computer games.

LCD- New in Computer Technology: Liquid crystal display, commonly referred to as LCD, is one of the latest innovations in computer technology. It is a flat display electronic device made up of a number of color or monochrome pixels placed in front of a light source or reflector. It is very popular among engineers, since it uses a small amount of electric power and can thus be used in battery-powered electronic devices. The first functional LCD was introduced in 1968, by a group at RCA in the USA headed by George Heilmerier and was based on the Dynamic Scattering Mode. The UK’S Royal Radar Establishment pioneered the liquid crystal technology in the late 1960s. The team at RRE supported the ongoing work by George Gray and his team, who discovered the cyanobuphenyl liquid crystals that had the required stability and temperature properties for application in the LCD. It is important to consider the features of the technology such as resolution, dot pitch, response time, matrix type, brightness, color support and viewable size.
