Document Summary
Information can be expressed by binary (0 and 1) Transistors, doesn t generate as much heat, much smaller and solid, semiconductor, that has no conductivity function. Byte became the basic unit of addressable computer storage. 1 word is a data that is stored, and moved around. Can be very easily converted to binary numbers and vice versa. Four bits in binary can directly converted into matching hexadecimal. If 2 positive numbers are added and the answer is negative (leading zero), it is an indication of an overflow. If adding 2 negative numbers (leading 1) results in no carry bit on adding place n-1>overflow. We can use it to efficiently compute with very large and very small numbers. 2a) in 4 and a half year, the processor will double 3 times. 100 transistors, in 4 and a half year, using the moore s law, there will be 800 transistors.
