television sets and toys. History The CPU evolved from miniature transmitters and integrated circuits which were developed in the early 1960s by IBM and other top technology companies of the time. By the early 1970s‚ transmitting integrated circuits were being manufactured commercially and engineers took that technology and developed the CPU. Harnessing the transmission abilities of integrated circuits‚ engineers added the ability to process information and memory power‚ Combined‚ these elements

For NMOS transistors‚ if the input is a 1 the switch is on‚ otherwise it is off. On the other hand‚ for the PMOS‚ if the input is 0 the transistor is on‚ otherwise the transistor is off. Here is a graphical representation of these facts: When a circuit contains both NMOS and PMOS transistors we say it is implemented in CMOS (Complementary MOS) Understanding the basics of transistors‚ we can now design a simple NOR gate. Next figure shows the implementation in transistors of the NOR gate and how

the beginning of the "Second Generation" of computers in 1947. Unfortunately‚ the 2nd Generation did not advance as much as most people hoped‚ but eventually‚ the "Third Generation" was brought about by the invention of integrated circuits in 1958. Integrated circuits replaced transistors‚ and many computer languages came out in this time. Many more computer companies were born during this time‚ and eventually this led to personal computers for everyday use. Microprocessors introduced the beginning

The first single chip CPU was the Intel 4004 invented in Nov 1971‚ a 4-bit processor meant for a calculator. It processed data in 4 bits‚ but its instructions were 8 bits long. Program and data were separate. In 1972‚ Texax Instruments followed the Intel 4004/4040 closely with the 4-bit TMS 1000‚ which was the first microprocessor to include enough RAM‚ and space for a program ROM‚ to allow it to operate without multiple external support chips. It also featured an innovative feature to add custom

DISTRIBUTION AUTOMATION Abstract— This White Paper on‚ “Power systems” addresses the working process‚ benefits and challenges of implementing Distribution Automation in electrical power distribution sector. The demand for electrical energy is increasing every day. Today over 24% of total electrical energy generated in India is lost in transmission (6%) and distribution (18%). The electrical power deficit in country is currently about 18%. Therefore reduction in distribution

Pentium Intel released its original Pentium Processor‚ also known as the Pentium 1‚ on March 22‚ 1993. The Pentium 1 replaced the Intel486 as Intel’s mainstream microprocessor for personal computing applications. While the Pentium 1 processors were specifically designed for use in desktop computers‚ later members of the Pentium family could accommodate laptops and other mobile devices. Reviewing some of the Pentium 1’s specifications can help you better understand the microprocessor’s capabilities

Brief History of Library Automation: 1930-1996 An automated library is one where a computer system is used to manage one or several of the library’s key functions such as acquisitions‚ serials control‚ cataloging‚ circulation and the public access catalog. When exploring the history of library automation‚ it is possible to return to past centuries when visionaries well before the computer age created devices to assist with their book lending systems. Even as far back as 1588‚ the invention of
