Security is gaining awareness and importance in recent years. And the access control system form a vital link in the security chain at present there are many security system available in the market but the paper proposed here is an economical electronic system. The consumption of low operating power, flexible and user friendly mechanical designs are the merits of this project the paper presents the technology of authorized access system by using 89c51 microcontroller and it has an added advantage
paper ... ... Is Intel's strategy for these products sound? Is it consistent? (example: Intel exited the DRAM business when it changed to a commodity business. What is different now that makes EPROM, a commodity product, attractive? Since they appear to be the current strategy, what is the nature of EPROM and FLASH from a business perspective? How well do they fit Intel's strategy Final thoughts notice that I kept the discussion a non-technical as possible, focusing instead on business and

In 1989 the cold start injector was deleted. The EPROM provided a wider pulse width on startup to provide
Introduction Morison’s (2004) essay, “Gunfire at Sea: A Case Study in Innovation”, is a commentary on the social implications of technological change that surrounded the introduction of continuous-aim firing in both the British and American navies. Morison discusses (1) conditions that foster technological innovation, (2) reactions to the changes produced by innovation, and (3) the elements of an adaptive society. The Cogan and Burgelman (2004) case, “Intel Corporation: The DRAM Decision”, paired
Introduction Computer memory refers to any physical device that has the ability of storing information either permanently or temporarily. For instance, the Random Access Memory (RAM) is a volatile memory that has the ability of storing information on various integrated circuits that are used by not only the operating system, but also by the hardware and software. In essence, there are two major types of computer memory namely Read Only Memory (ROM) and the Random Access Memory (RAM). ROM refers
What is memory? Memory is a computer system's essential workspace. Memory is a large array of the word or bytes. Memory can be defined as a place to store data. It works in one behind the other with the CPU, or microprocessor, to store information, programs, and prepared data that can be made quickly and straightforwardly open to the CPU or to other system devices. Memory is central to a computer's operation because it forms the critical link between software and the CPU. Computer memory likewise
1. What types of printers are most common today? What is the cost of a color printer versus a black-and-white one? Compare and contrast laser and inkjet printers in terms of speed, cost, and quality output. What kind of printer would you buy or have you bought? Ans: Most Common types of PRINTERS Inkjet printers Inkjet printers squirt little dabs of ink onto the page to imitate content and pictures. Inkjets are famous on the grounds that they're generally modest. There are additionally numerous models
Intelligent Transportation Systems (ITS) have received much attention in recent years in academia, industry and standardization entities due to their wide impact on people's life as their scope to provide vital applications and services to improve transportation safety and mobility and to optimize the usage of available transportation resources and time. ITS applications and services rely on advanced technologies to be deployed and distributed among the intelligent infrastructure systems and vehicles
The Different Types of Memory Devices This technical report will look at various different memory devices and how they are implemented in a standard computer system. Internal memory devices such as ROM, PROM, RAM, SRAM, DRAM, SIMM and DIMM will be looked at in order to give a clear idea of how each one operates, and external devices such as memory sticks will also be touched upon. Each of these devices uses different types of memory in different ways. Over the course of this report, each
Introduction As a Computer Science student in Computer Engineering/Computer Science 285, I’ve grown to appreciate using a prototype board to get through the class. As a person more inclined to software than to hardware, the sixteen-week journey has been a process. Part of my appreciation comes from my curiosity in the equipment of this class, in learning about other components and the potential the board had. Learning not only about the 8051 microcontroller and board but also how to deal with it
Q:1What is the difference between cache memory and RAM?(5 lines only) Ans: RAM is abreviated as Random Access Memory, is the main memory of computer in which the running programe is stored temporarily , it losts its memory when computer is turned off. While Cache memory is a special memory used to decrease the average time taken by RAM to access the programe. Cache memory is smaller memory as compared to RAM but it is much faster then RAM. Q:2There are three types of printers what are they? Give
(1)Virtual Machines The fundamental idea behind a virtual machine is to remove the hardware of a single computer and make it a self-contained operating environment that behaves as it is a separate computer. Essentially, the virtual machine is software that executes an application and isolates it from the actual operating system and hardware. CPU scheduling and virtual-memory techniques are used so that an operating system can create the illusion that a process has its own processor with its own

OBJECTIVE OF THE PROJECT: The project was an attempt to provide a solution to the perennial problem of parking of vehicles. Due to increase in the population of the urban areas, especially metropolitan cities and more and more people using cars and other vehicles, parking of these is a very big problem. So, this project was an attempt in the same direction, that is, an automated car parking which is a feasible solution. The objective of this project was therefore to keep a check on the number of
Computer Architecture 1. There have been a lot of developments in microprocessors since the 286 chip. The 286 CPU are no longer sold and are very rarely found in commercial use today because of its running speed, which is between 10MHz to 20MHz. This processor has a 24-bit address bus, and is able to address up to 16 million different address locations. It also has two operating modes, which are real mode and protected mode. The real mode is basically for normal DOS operations and it uses only
Writing a "Private 3M Script" First it is important to define the term "3M." The term "3M" simply refers to a script's ability to unlock all of the channels, based on the saying "All for one, and One for all!" from the "3 Musketeers," (which came from the old days of hacking cable boxes where all channels were viewable through one channel). Anyway, "3M" now is just a generic term for a card that has all channels open and no stealth or write protection. In stealth scripts, the "3M" code refers to
