1.There are several possibilities:increase the efficiency of present techniques in order to reduce energy consumption,and invest into new technologies such as solar power,wind power and fuel cells,for example.
2.A computer is a programmable machine that receives input,stores and manipulates data,and provides output in a useful format.
Computers are available in different shapes,sizes and weights,due to these different shapes and sizes they perform different sorts of jobs from one another and therefore can be classified in different ways.
The working process of a computer is based on a binary system.Each problem is described in a sequence of 1 and 0,via software programmes a solution can be calculated.
A general purpose computer has four main components:the arithmetic logic unit (ALU),the control unit,the memory,and the input and output devices (collectively termed I/O).These parts are interconnected by busses,often made of groups of wires.
