Characteristics of computers

SpeedComputers process data at extremely fast rate, at millions of instructions per second. A computer can perform a huge task that a normal human being may take days or even years to complete. The speed of a computer is calculated in MHz (MegaHertz) ie. One Million instructions per second.

2. AccuracyComputers are very accurate. The level of accuracy depends on the

instructions and type of machine being used. Faulty instructions for data

processing lead to faulty results. This is called GIGO (Garbage In Garbage

Out).Computer’s physical circuits rarely make errors, if the data and

instruction are correctly fed. Most of the errors occurring in computers are

either hardware errors or human errors.

Scientific Notation1. C2H6 + 3.5 O2 2 CO2 + 3 H2O

2. (X + Y)2 = X2 + Y2 + 2XY

Thus the document has been created as per the format given.
