INTRODUCTION AND BACKGROUND Time and attendance system are the modern-day equivalent of the paper time sheet or punch clock. This Electronic attendance is designed to explain how a system helps a teacher to keep an accurate attendance records for their students. An Electronic attendance system serves as a time log that is set up as a computerized database. The complex ideas are presented and developed logically. Important terms are defined in an easy and comprehensible manner that the reader

Would you use this web page when writing a term paper about the history of computers? A Brief History of Computer Technology A complete history of computing would include a multitude of diverse devices such as the ancient Chinese abacus‚ the Jacquard loom (1805) and Charles Babbage’s ``analytical engine’’ (1834). It would also include discussion of mechanical‚ analog and digital computing architectures. As late as the 1960s‚ mechanical devices‚ such as the Marchant calculator‚ still found

Before computers there were not telephone answering machines‚ handheld calculators‚ fax machines‚ personal computers. People did what they had to do without these things. People wrote letter by hand or with a typewriter‚ they also kept track of data and numbers in ledgers. They were not texting each other‚ there was either in person or over the phone. . Computers are integral to our daily lives and there are millions used daily. Computers are used at home‚ work‚ and school. They are also embedded

We were assigned with the task of designing and building a digital clock that displays the time in Binary. First a power supply that outputs a 60Hz square wave is fed into the circuit. We used 74160 decade counters in the project. A 74160 divided the clock down to 6Hz‚ and then a truncated 74160 divided it down to a 1Hz wave that would be the input for the clock. This clock will display in military time. The 1HZ is equal to one second and is fed into the first 74160. There are six 74160 counters

A computer is not an acronym and is sometimes abbreviated as comp or ’puter. The term "computer" was originally given to humans who performed numerical calculations using mechanical calculators such as the abacus and slide rule. The term was later given to a mechanical device as they began replacing the human computers. Today’s computers are electronic devices that accept data (input)‚ process that data‚ produces output‚ and then store (storage) the results. The first computer was called the ENIAC
