- 1st Generation: This was from the period of 1940 to 1955. This was when machine language was developed for the use of computers. They used vacuum tubes for the circuitry. For the purpose of memory, they used magnetic drums.
- 2nd Generation: Here they advanced from vacuum tubes to transistors. This made the computers smaller, faster and more energy efficient. And they advanced from binary to assembly languages.
- 3rd Generation: The hallmark of this period (1964-1971) was the development of the integrated circuit.
- 4th Generation: The invention of the microprocessors brought along the fourth generation of computers. This was when we started producing computers for home use. Another important aspect is the development of higher computer languages like C++ and Java.
- 5th Generation: This is the present and the future of the computer world. The defining aspect of this generation is artificial intelligence. The use of parallel processing and superconductors are making this a reality and provide a lot of scope for the future.

A torch is a portable electric lamp which uses two or more cells to light a small bulb. A torch is used to provide light in the dark when it is switched on.
A torch consists of a simple electric circuit in which two or more cells are connected to a torch bulb through a sliding switch. When the torch is needed to provide light, the sliding switch is closed by pushing it forward so that the circuit is completed and the bulb of the torch lights up.
When the torch is not needed, the sliding switch is opened by pushing it backwards so that the circuit breaks and the bulb are turned off.

A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles "a" and "b" add up to 180°, so they are supplementary angles. NOTE: Squares, Rectangles and Rhombuses are all Parallelograms. In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles "a" and "b" add up to 180°, so they are supplementary angles. It is a quadrilateral with two pairs of parallel, congruent sides. Its four interior angles add to 360° and any two adjacent angles are supplementary, meaning they add to 180° .
