A computer is a machine that manipulates data according to a list of instructions.The first devices that resemble modern computers date to the mid-20th century (1940–1945), although the computer concept and various machines similar to computers existed earlier. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers(PC). Modern computers are based on tiny integrated circuits and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wristwatch and be powered from a watch battery.Personal computers, in various forms, are icon of the Information Age and are what most people think of as "a computer"; however, the most common form of computer in use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's toys.The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turin thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform.Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.
ICT Development
Ago, like we know, people was hard to communicated when they located in two different places. Time comes time, they started to communicate by using strike a drum, fire and smoke. And then, they stoped to used fire and smoke and they used a small massage that can sent by pigeon. The newest was Semaphore. Then, a man named Alexander Graham Bell fely hard to communicate with the othe people. Finally, he succeed to made an important thing in Information history, telephone. Nowadays, telephone is an important things for all people. And, some of them are using handphone. And we can used internet and the other facility in computer now for informationBut, reseacrher start to look for a faster communicator things that can we used in the future. The researcher said, that will looked like a micron speaker. The micron speaker will placed in our tooth (just one). If we want to call someone, just close the teeth tightly and said the name that you want to call. If the speaker broken, just pull out it with a toothpicks and eat it.
There's more that i would to tell you. But, I think that's enough to show you how fast the technology and informaion technology is......
ICT's Research
Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.
Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.
When computer and communications technologies are combined, the result is information technology, or "infotech". Information Technology (IT) is a general term that describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information. Presumably, when speaking of Information Technology (IT) as a whole, it is noted that the use of computers and information are associated. Then the ITAA found the most important part in Information Technologh Development. That is:
1. IT must has a good function
2. IT must always been the useful Things in daily life
