lighting mechanism as LCD panels produce no light of their own. The conventional backlit LCDs are now being widely replaced by two types of LED backlit LCD displays. Active Matrix-This design depends on the usage of thin film transistors (TFT) — basically‚ tiny switching transistors and capacitors. One of the most important technologies behind liquid crystal display. These are arranged in a matrix on a glass substrate. They are required to switch the LCD’s pixels on and off rapidly. In LCDs‚ each colour

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

It is the other component of the motherboard that acts like the organs of the system. These chips may be small as a grain of rice and bigger as a coin. Transistor is a small‚ black in color and rectangular in shape. It is sometimes recognizable because of its three metal legs attached on it. Transistors is consists of thousand or even million of IC (Integrated Circuit) packed in one part

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
