dependent upon integrated circuit technology. During the 1970s‚ performance continued to improve at about 25% to 30% per year for the mainframes and minicomputers that dominated the industry. The late 1970s saw the emergence of the microprocessor. The ability of the microprocessor to ride the improvements in integrated circuit technology more closely than the less integrated mainframes and minicomputers led to a higher rate of improvement—roughly 35% growth per year in performance. 2 Chapter 1 Fundamentals

CHAPTER I THE PROBLEM AND ITS BACKROUND A. Introduction Now days in many public places such as malls‚ multiplex systems‚ hospitals‚ offices‚ market areas there is a crucial problem of car parking. The car-parking area has many lanes/slots for car parking. So to park a car one has to look for all the lanes. Moreover this involves a lot of manual labor and investment. So there is a need to develop an automated parking system that indicates directly the availability of vacant parking slots in any lane

technology‚ some of which was made possible through the use of computers themselves. The computers have evolved considerably from being basic set of components made up of Integrated Circuits (ICs) to have a much complex architecture involving microprocessors with millions of mini components on them. The architecture of computer has also evolved with extensive use of new techniques such as pipelining and caching‚ each of which has evolved itself. The evolution of the performance of computer systems

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
