what is computer?

                 A computer is an electronic hardware device. It operates and functions under the control of instructions in the memory called PROGRAMS. They are two types of programs, system programs ,and application programs. Sytem programs control the computer and monitor activities of the computer while appliction programs perform a specific task .For instance, Word processing, spreadsheets and games.People use the computer as a means to do certain tasks and attain certain objectives.

                      There are six elements of computer system. First on the list is People. They are the most important element of a computer system. They run and operate the computer because computers will not work on their own. They need people to operate on them. the second element is Procedure. Thy are step by step instruction to follow when using hardware and software. They are programs or instructions that a computer must follow  to do its task. The purpose of software is to process data into useful information for people. then, The fourth essential element that a computer system must have is hardware. It is the physical  equipment that you can feel and touch. Hardware include the CPU,mouse,printer,speaker,and the monitor.

                  A computer works like a human brain. The store information from our sense of touch,sight,
smell, and taste. The brain uses these to guide human actions. So does the computer it needs information that enters the computer is called DATA. It is one of the computer system important elements. this includes texts, and numbers,sounds,images,and videos that we input in the compiler for processing and lastly the connectivity. It means that a computers must be connected to others computers especially through the internet. Using the internet , people can share and access data from all over the world.


                      This so called programmable electronic device can receive and accept data, then process using the program set by the user.  Data entered in the computer are in the form of either texts,pictures and images,sounds,and  videos. The computer processes these  data and then produce an output information for use now or in the future by people. Processed information for  future use one stored in the computer's storage. Computers  today have a lot storage capacity to save information.


                         The computer is an electronic machine that is capable of accepting data and manipulating or processing  this data into meaningful results results of information. It is a device that performs mathematical and logical operations and process results in a form readable by humans or by machines. Early computers were mainly used to compute; that is to add,subract,multiply and divide so on. TOday, computer do a great variety of other task such as text processing and the handling of huge quantities of information.

information technology is not a dead-and job.

So from the definition itself, information technology is very rare job and it is not a dead-end job but it’ is a continuous learning and innovating of a lot of things. Have you asked that at yourself why it is so essential today? Why it INFORMATION TECHNOLOGY is just like a bundle of all things? Just look around you and you will notice it why. For instance, the piping system; the electrical lining system; the bicycle; roads; and highways; the library; the printing press; the telephone; the airplane; and more are few that information technology can bundle of. They are product of technology and with the help of information technology we all know how to use it and we can’t deny the fact that our generation is embraced by high technology.It was due to the advancements in technology that water from natural resources homes through robust water storage transmission systems. It was due to technology that food could be processes and preserved. It became easy for us to satisfy our basic needs because of technology. We can lead a luxurious life. It brought a huge change to civil engineering and architecture. Underwater civil structures and tall buildings scarping the sky could be built, thanks to technology and to information technology. The different types of constructions like mobile homes, earthquake-resistant buildings and modular homes could be created due to advancing technology. Businesses, small and big, need technology to be part of their infrastructure. Expansion by companies takes place by means of technology. Technological development gives organization the strength to spread their wings far and wide.
