Hardware Hardware refers to all the machinery that will be used by the firm in the information system. The most important hardware in the information system is the computer. The computer has its own important hardware parts like the storage, the control unit, the processors and many others. Some people refer to the hardware part of the information system as the central processing unit because this is actually where all the data processing for the system is done. The hardware of the computer must have five important parts for it to function optimally (O'Brien, 2003) Inp ut This is the means by which the computer accepts data that is fed into it via the input devices. The most commonly used input device is the keyboard where the user types instructions that the computer processes. Other input devices include microphones for sound input, scanners for digital input and mice. Process Once the computer has accepted input, it must have a means by which it will process data.

Rural Delivery Journal - Essay Example My town is a small community at the base of a mountain range. Most residents of the community have lived in the area for multiple generations. My family has lived there for four generations, essentially the entire time since our ancestors immigrated to America. There is a single convenience store that serves the community. It sells gas and grocery items. The only other commercial/industrial building is the post office that serves the community.

My parents’ grammar and topics of conversation are sometimes embarrassing. Like Tan, however, I am very proud of my family. I have skills and knowledge that many people I attend college with will never have. I can both hoe a row of corn and write an essay with equal skill. John Q.
