An address
is the name of particular memory location or cell. Each memory
location (word or byte) has its own unique address or number just like a post office
box*. For example, if the computer contains 100
memory cells, their respective
address might be the numbers* from 1 to 100 (or 0 through 99). And instead of
saying "A word is in a memory cell", the computer personnel say, "The
contents
(содержимое) of an address is a word."
Reasonable operations are mathematical and logical. Mathematical operations
include arithmetic and algebraic operations. Arithmetic operations are addition,
subtraction, multiplication,
division, taking a square root, etc.; and algebraic
operations are called raising to a power as well as differentiating and integrating.
Logical operations include comparing, selecting, sorting, matching, etc. These are
operations which may be performed either on numbers, or on expressions consisted
of letters such as ordinary words. A very important logical operation performed by
a computer is determining, i.e., which of two operations is to be performed next.
Notes
1. numerical quantities - численные значения (величины)
2. Most human beings could not take even 12-digit number per second -
Большинство людей не смогли бы воспринять даже 12-значное число в
секунду
3. just like a post office box - точно так же как почтовый ящик
4. their respective addresses might be the numbers - их соответственные адреса
могли бы быть числами
