Computer technicians work in a variety of settings, encompassing both the public and private sectors.Because of the relatively brief existence of the profession, institutions offer certificate and degree programs designed to prepare new technicians, but computer repairs are frequently performed by experienced and certified technicians who have little formal training in the field.
A decimal computer is a computer that represents and operates on numbers and addresses in decimal format – instead of binary as is common in most modern computers. Some decimal computers had a variable word length , which enabled operations on relatively large numbers.
Bi-quinary coded decimal is a numeral encoding scheme used in many abacuses and in some early computers, notably the Colossus. [2] ... 5: 0010-0 6: 0010-1 7: 0001-0 8 ...
In computer science, the precision of a numerical quantity is a measure of the detail in which the quantity is expressed. This is usually measured in bits, but sometimes in decimal digits. It is related to precision in mathematics, which describes the number of digits that are used to express a value. Some of the standardized precision formats are
The demand for jobs in the electronics engineering and service fields is the result of a recent proliferation of both consumer and industrial electronics products. The design, installation, servicing and maintenance of this equipment has created significant employment opportunities in the electronics industry. [6]
A repeating decimal is an infinite decimal that, after some place, repeats indefinitely the same sequence of digits (e.g., 5.123144144144144... = 5.123 144). [4] An infinite decimal represents a rational number , the quotient of two integers, if and only if it is a repeating decimal or has a finite number of non-zero digits.
A decimal floating-point number can be encoded in several ways, the different ways represent different precisions, for example 100.0 is encoded as 1000×10 −1, while 100.00 is encoded as 10000×10 −2.
1. Denotes subtraction and is read as minus; for example, 3 – 2. 2. Denotes the additive inverse and is read as minus, the negative of, or the opposite of; for example, –2. 3. Also used in place of \ for denoting the set-theoretic complement; see \ in § Set theory. × (multiplication sign) 1.
