In mathematics, the number of different single-digit symbols used in a particular number system. In our usual (decimal) counting system of numbers (with symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) the base is 10. In the binary number system, which has only the symbols 1 and 0, the base is two. A base is also a number that, when raised to a particular power (that is, when multiplied by itself a particular number of times as in 102 = 10 x 10 = 100), has a logarithm equal to the power. For example, the logarithm of 100 to the base ten is 2.
In geometry, the term is used to denote the line or area on which a polygon or solid stands.The bottom side of a geometric figure from which the altitude can be constructed.
(In a digital numeration system) The positive integer that is equivalent to one in the next higher counting place; SYN. radix.
1. In mathematics, a number that is raised to the power specified by an exponent. For example, in 23 = 2 x 2 x 2 = 8, the base is 2. 2. In mathematics, the number of digits in a particular numbering system. With microcomputers, four numbering systems are commonly used or referred to—binary, octal, decimal, and hexadecimal—and each is based on a different number of digits. The binary, or base-2, numbering system, which is used to discuss the states of a computer’s logic, has two digits, 0 and 1. Octal, or base-8, has eight digits, 0 through 7. The familiar decimal, or base-10, numbering system has ten digits, 0 through 9. Hexadecimal, or base-16, has sixteen digits, 0 through 9 and A through F. When numbers are written in a particular base, the base is often subscripted and enclosed in parentheses after the number, as in 24AE(16) = 9,390. Also called: radix. See also binary1, decimal, hexadecimal, octal.

(Electronics) The part of a transistor that separates the emitter from the collector.
One of three terminals (emitter, base, and collector) in a bipolar transistor. The current through the base controls the current between the emitter and the collector. See also transistor.
The insulating foundation of a printed circuit board. See also circuit board.

Chemistry, compound combining with acid to form salt.
In chemistry, a substance that accepts protons, such as the hydroxide ion (OH-) and ammonia (NH3). Bases react with acids to give a salt. Those that dissolve in water are called alkalis.
Inorganic bases are usually oxides or hydroxides of metals, which react with dilute acids to form a salt and water. A number of carbonates also react with dilute acids, additionally giving off carbon dioxide. Many organic compounds that contain nitrogen are bases.
Any of various water-soluble compounds capable of turning litmus blue and reacting with an acid to form a salt and water; SYN. alkali.

2. A flat bottom on which something is intended to sit.
3. The bottom or lowest part.
4. Place that runner must touch before scoring; SYN. bag.
5. The place where one is stationed and from which missions start and end; SYN. home.

Množina: base addresses

The part of a two-part memory address that remains constant and provides a reference point from which the location of a byte of data can be calculated. A base address is accompanied by an offset value that is added to the base to determine the exact location (the absolute address) of the information. The concept is similar to a street address system. For example, “2010 Main Street” consists of a base (the 2000 block of Main Street) plus an offset (10 from the beginning of the block). Base addresses are known as segment addresses in IBM PCs and compatibles; data in these computers is identified by its position as a relative offset from the start of the segment. See also absolute address, offset, relative address, segment.
