today. Inside a dynamic RAM chip‚ each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor. These are‚ of course‚ extremely small transistors and capacitors so that millions of them can fit on a single memory chip. The capacitor holds the bit of information -- a 0 or a 1 (see How Bits and Bytes Work for information on bits). The transistor acts as a switch that lets the control circuitry on the memory chip read the capacitor or change its state.

components. Some of these components are termed as active components because they take part in the transformation of the energy while other components‚ which only dissipate or store energy‚ are called as passive elements. The vacuum tubes‚ rectifier‚ transistors are some of-the common active while the resistances‚ which dissipate the power and energy storing elements such as capacitances and inductances are known as passive elements. The transformers may be regarded as a matching device. The success

and ENIAC machines – the UNIVAC is the first every commercial computer which was purchased in 1951 by a business – the US Census Bureau. Second Generation (1956 – 1963) – Transistors The replacement of vacuum tubes by transistors saw the advent of the second generation of computing. Although first invented in 1947‚ transistors weren’t used significantly in computers until the end of the 1950s. They were a big improvement over the vacuum tube‚ despite still subjecting computers to damaging levels

Grade 9 Task Term 3 Hydraulics and Pneumatics Section: A 1. a) Good examples of hydraulic systems include automotive brakes‚ and the control systems of large aircraft. Hydraulic systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics gives high forces with low losses‚ thanks to the virtual incompressibility of hydraulic fluids. Pneumatics is usually less efficient‚ though simpler since the "reservoir" in the circuit is the atmosphere
