Advance technology in Computer

Technology is most important in today’s life from smaller to high multinational giants Day by day Technology is getting changed and it has made many favorable changes in devices and technology like monitors, keyboard, mouse, mobile laptop, internet technologies and many other things.

Hardware devices that accept the information which is inputted and give output on command. Hard disk drive, CD ROM, floppy drive, monitors, printer are some examples of input/output devices and external storage devices.

Monitor, keyboard and mouse all have been replaced with latest technologies like LCD monitor, wireless keyboards and wireless mouse. LCD stands for Liquid Crystal Display that works on tiny crystals and TFT monitors stands for Thin Film Transistor.

OLED is used for display in computer monitors and TV, camera etc.OLED is stand for Organic Light Emitting Diode. There are two types of OLEDs small molecule OLED and polymer OLED.OLED expresses only pure colure. The OLED color matrix is arranged in red, green, and blue Pixels, that are mounted directly to a printed circuit board and gives is high definition quality.

Storage devises are replaced by more capable and smaller devices. For various situation different type of storage devices are used. Hard disk is a storage device that stores data and software for long time. The main memory of a computer device is random access memory (RAM).Data can be stored and retrieved from every location at very high sped.

Floppy disk that was used to transfer data and as an external storage facility, which is now outdated. Pen drive and compact disks (CD & DVD) has taken place of floppy disk.

CD ROM is used for installation of software and easy way for companies, institute and any organization to demonstrate their project, study material and information, and programs respectively. Data or pictures can be transferred from one computer to another computer by using CD ROM.

While a computer process on a request, the speed of data transfer depends on these devices and memories that work together, In other words it can be said that computer memories or devices determine the speed of any operation when the information is being retrieved from hard disk. Every program has a certain part of memory. Graphic software takes more time in loading because it needs a lot of space of memory. Now computers and laptops are coming in market with 3-4 GB random access memory (RAM) so that one can get more and more speed according to need.

There have been a lot of changes today and these devices are still getting changed with the latest technologies.

Information technology

Today Information technology is the key of development of a nation in the present time of computerized world। It merges the computer and communication together in order to make availability of latest information easier to every one in the world At this time there are many different business organization cannot work if they don’t have the require data and information to continue their business activities. Now a days we can take many examples, to explain the importance of information technology like an Airline reservation company or railway department that may no be able to prepare the passengers list for its different flights and seats, if they do not have required data about passengers available. A bank may never ever perform its banking function without the data and information regarding its customers, services, business perspectives and many other activities.

Almost old-technology have become changed or been replaced with latest information and technology. In the same way, the variety of input and output devices allows users to select the most effective tool for their needs. As computer is a very important tool for quick and accurate calculation or production of our needed information,. The second element of information technology is communication, that actually means how to put the computer in a network to transmit their output i.e. information to other computer device.

Technological advancements in computers benefit are same in businesses and individuals. All these developments have led to easier and more efficient ways to input, process, and review data. Information technology plays very-very important role almost in all the business organizations, mostly in the form of computer based information system like Management information system, Decision support system, Executive information System and many others. The information is collected from different type data sources in many business organizations.

The benefits of information technology are highly challenging and outstanding factor, IT now a day is dissolving in our daily lives day by day almost all aspects of our social national and international life affairs in a very true sense. The speed of these functions, when performed on a computer, may increase or decrease depending on a variety of factors. This is highly essential or crucial for the betterment of a nation.
