Computer development is often referred to the different generations of computing devices. With each generation which includes the first to the fifth‚ significant changes have occurred resulting in lighter‚ cheaper‚ powerful‚ more efficient and convenient devices. This change in computing devices has caused businesses to rethink and revamp the ways they operate to meet consumer demands‚ reduce cost and compete efficiently. This paper will also examine computer- based information system and the impact

Personal Computer A personal computer is a computer that is based on a microprocessor‚ a small semiconductor chip that performs the operations of a c.p.u. Personal computers are single-user machines‚ whereas larger computers generally have multiple users. Personal computers have many uses such as: Word processing‚ communicating

circuit technology improvement coupled with computer architecture innovations have resulted to a speed of CPU performance development unprecedented since the middle of the 20th century. Computer architecture innovations has continuously improve Microprocessor-based machines at a speed range of 1.5 and 2 times per year for the last seven years. Improvement speed for minicomputers or mainframes computers are approximately 25% every year. Seemingly‚ recent

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed‚ the computer can solve more than one kind of problem. Ads by Plus-HD-V1.5c×Conventionally‚ a computer consists of at least one processing element‚ typically a central processing unit (CPU)‚ and some form of memory. The processing element carries out arithmetic and logic operations‚ and a sequencing and control

A microsequencer or Control ROM would be used to execute logic to provide data and control signals to regulate function of the component ALUs. Examples of bit-slice microprocessor modules can be seen in the Intel 3000 family‚ the AMD’s Am2900 family the National Semiconductor IMP-16 and IMP-8 family‚ and the 74181. During the era this technique was most common (mid-1970’s through 1980’s)‚ there was some debate over how

Embedded Technology For Vehicle Cabin Safety Monitoring And Alerting System ABSTRACT Motor vehicles are the prime source of transportation where vehicles with A/C play a major part. This paper designs an embedded system for a vehicle cabin‚ which senses the gases like carbon-monoxide and oxygen and displayed at each and every second. If the level of the CO increases than the normal level (30ppm) or the level of the oxygen decreases than the normal level (19%) then an alarm is generated automatically

processor or central processing unit controls the functions of most electronic products. The CPU accepts the input data‚ processes the information and sends it to the component that is in charge of executing the action. CPUs are also known as microprocessors and are at the center of any computer system. Although CPUs are most often thought of as a computer chip‚ they can also be found in many other electronic devices including cell phones‚ hand held devices‚ microwaves‚ television sets and toys.
