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

fourth generation computer - A computer built using Very Large Scale Integration(VLSI) integrated circuits‚ especially a microcomputer based on a microprocessor‚ or a parallel processor containing two to thousands of CPUs. VLSI made it routine to fabricate an entire CPU‚ main memory‚ or similar device with a single integrated circuit that can be mass produced at very low cost. This has resulted in new classes of machines such as personal computers‚ and high performance parallel processors that

applications. During this time the first electronic digital computers were developed. Originally they were the size of a large room‚ consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines‚ and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices‚ and mobile computers can be powered by small batteries.

They are used in logic circuits to turn heaters on and off. LDR’s (light dependent resistors have a high resistance in the dark but a low resistance in the light. As darkness falls‚

combines both positive and negative channel in the same circuit‚ and consume lower amounts of power when compare with single polarity devices. In 1963 C. T. Sah and Frank Wanlass prove that combining both channels in a circuit drew close to zero power in standby mode. RCA laboratories first produce CMOS technology for aerospace and commercial applications. The first static RAM was introduced in 1968 with 288-bit capacity. In the first integrated microprocessor with CMOS technology only had 4bit and

Purpose OF Study The purpose of this paper is to explore the extent to which social factors‚ delineated in terms of interpersonal communication variables‚ are associated with what is referred to as Internet addiction among college students at a large Midwestern University. We also want to determine if gender‚ locus of control‚ and individual sociability moderate the relationships between communication variables and Internet utilization. This type of analysis makes the current study more systematic

that was consistently at the forefront of innovation. In the integrated circuit industry‚ a company’s innovation is fundamental to its success. “Moore’s Law”—the industry-wide benchmark for innovation—was created by Intel cofounder Gordon Moore. The law claims that the number of components on a chip doubles every two years. Intel’s adherence to Moore’s law is costly. Intel’s strong customer ties with major buyers of integrated circuits have also proved beneficial. IBM‚ Intel’s largest buyer‚ has
