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

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

This will help the interconnects serve as heat spreaders in future generations of integrated circuits‚ according to Murali. They used electron beam lithography to construct

every 10 pulses. The counter drives the transistors‚ which form the triac firing circuit. The transistors fire the triacs and they provide sufficient current to the load. Decorative bulbs are connected as load for each triac. The bulbs are sequentially turned ON and OFF in forward and reverse way. [pic] The IC 555 works as the pulse generator and feeds the clock pulses to IC 4017. IC 4017 is the heart of this circuit. It works as a counter and gives the output after every 10 pulses. It drives
