Computer is the most amazing gift of science. Almost everyone have one or more computer. This device was developed by Charles Babbage. Computer is a part of our life today. Computer can be used on many thing like school, business, government and etc… we can see computer anywhere we go around the world. Computer is so amazing with many functions. Four basic function if computer are input, processing, output and storage. Input collectively refers to all the resources used in creating a program. This usually consists of a programmer entering code into a computer with a keyboard.
Processing collectively refers to all of the internal functions the computer uses to control and make sense of information. The most basic components are a control unit, an arithmetic logic unit and random access memory for temporary storage. This represents a very simple model of a computer. Modern computers will add other processing components such as a multitasking operating system Output is the display of information to the user. This can occur through the monitor, by way of audio through the speakers, or on paper via a printer. Output can also be written to a storage device like a CD-ROM or flash drive. Storage consists of any means by which data can be permanently saved. Some examples include internal and external hard drives, floppy disks, CDs, DVDs and memory sticks. This component was not always present in the IPO model as it is not strictly necessary for a basic computer to function, but has been added as permanent physical memory has become a standard part of all modern computers.
The Term Paper on Buying A Computer
Buying a Computer today is much more complicated then it was ten years ago. The choices we have are abundant, and the information we must gather to make those choices is much greater. The average consumer is a more educated buyer; they at least have some ideas of what they want in a computer. Yet, we must still ask ourselves these significant questions; such as: What will the primary function of ...
Computer created base on living things. Computer also has a brain that control all functions and activities. Brian of computer called microprocessor. Microprocessor is an electronic device that can carry out complex calculations in the blink of an eye. Microprocessor also found in car, television and some many other electronic device. That mean computer is not just a laptop or desktop that we use every day, but computer also use on many different things around us. Car also contain a chip that control many function of the car. Now cellphone also uses as computer. Smartphone is the cellphone that contain a computer chip. Smartphone can works almost the same as laptop or desktop. The first computer is the ENICA machine by John W. Mauchly and J. Presper Eckert. ENICA is the first machine that using 18,000 vacuum and machinery required to keep the cool took up to nearly 1800 square feet. Based on the first computer, many newer model computers made.
People always trying to get better and they keep creating many new styles of computer. From the first computer that took up to 1800 square feet of space to the little computer that we can carry on our hand. It’s never stop there and keep getting better every day. Computer can be the most important thing in our life that can make things easier. Almost everyone using computer right now but not many of them knows exactly how the computer works. People don’t know how hard the scientist worked to create this amazing thing for us. We should respect the hard work of people that created computer that make our life much easier.
