transistor is a semiconductor device that amplifies and switches electrical currents. They are the core component of any modern electronic devices‚ such as computer‚ telephones and other electronics. Nowadays most transistors are use to produce integrated circuits. There were a numerous inventions‚ or problems with the inventions that lead to the birth of the transistor. Radio signals‚ could be sent carrying information over a long distance away; the only problem was there was no device to receive the

Resistor‚ Capacitor and Inductor make up some of the basic elements in any circuit system. Memristor or a memory resistor is described as a resistor which can store data. This characteristic of the memristor is the reason it is most sought after for use in memory related systems. [6] The concept of memristors was first theorized by Prof. Leon. O. Chua in 1971. It wasn’t until Stanley Williams invented the crossbar latch in 2008 that the scientists realized the memristor could be made possible. It

PERSONAL COMPUTER “Microcomputer” is a term used to refer to computers that contain a microprocessor. This type of computer is known by its familiar name- the PC. This is the type of computer that someone is mostly to use. As the name suggest‚ a microprocessor is a very small processor. This is in the form of a silicon chip like a Pentium Processor. Since they use smaller processors‚ microprocessors are smaller than the other form of computers‚ yet they are the most important of all. They

Definition of ’Moore’s Law’ An observation made by Intel co-founder Gordon Moore in 1965. He noticed that the number of transistors per square inch on integrated circuits had doubled every year since their invention. Moore’s law predicts that this trend[->0] will continue into the foreseeable future. Although the pace has slowed‚ the number of transistors per square inch has since doubled approximately every 18 months. This is used as the current definition of Moore’s law. History The term

semiconductors devices demands a greater purity than an afforded by some metallurgical grades of silicon. Silicon wafers used as substrates in the manufacture of discrete electronic devices that include transistors‚ and also in the development of integrated circuits that are found in computer chips. The reason for silicon is that silicon has a wonderful property of forming a high quality oxide when exposed to oxygen at high temperatures. This oxide forms insulating films and allows many devices to be

Second Generation Computers (1956-1963) The computers built in the 1950s and 1960s are considered the 2nd generation computers. These computers make use of the transistors invented by Bell Telephone laboratories and they had many of the same components as the modern-day computer. For instance‚ 2nd generation computers typically had a printer‚ some sort of tape or disk storage‚ operating systems‚ stored programs‚ as well as some sort of memory. These computers were also generally more reliable

The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. With each new generation‚ the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization‚ speed‚ power‚ and computer memory has proportionally increased
