put-, puta-, -pute, -puter, -puting, -putate, -putation, -putative
(Latin: putatus past participle of putare: to think over, consider, reckon, count; to trim, prune, lop, cut, clean, clear, unmixed)
From Latin, puto-, putare: literally; especially of trees, "to lop, to prune" and "to cleanse, to clear"; then (1) "to clear up, to settle"; especially, of accounts; (2) "to reckon, to estimate, to value"; (3) "to consider, to hold, to believe, to think".
2. Determining something by mathematical or logical methods.
3. Problem solving that involves numbers or quantities.
2. To yield a result; especially, a correct result, from a calculation: Sharon found out that the numbers that were provided just don't compute
2. A device that performs high-speed mathematical or logical operations or that assembles, stores, correlates, and otherwise processes information.
3. Someone who utilizes a programmable electronic machine that has special procedures for accomplishing results: Computers can perform complex and repetitive procedures quickly, precisely, and reliably; as well as, quickly storing and retrieving large amounts of data.
The physical components from which a computer is constructed and which provide electronic circuits and input/output devices are known as "hardware".
Most computers have four types of hardware components: CPU, input, output, and memory.
The CPU, or central processing unit, executes programs known as "software" which direct the computer what to do.
Input and output, I/O, devices allow the computer to communicate with the user and the outside world.
There are several kinds of memory for computers that include fast, expensive, short term memory, known as RAM, to hold intermediate results, and slower, cheaper, long-term memory; such as, magnetic disk and magnetic tape, to hold programs and data between jobs.
Origin of the word computer
The term computer is a word which was formed in English from the verb compute and it has a recorded history going back to 1646, when it was used to mean "a person who computes".
In 1897, the word was first recorded as "a calculating machine", although that particular machine, which was "of the nature of a circular slide rule", did not resemble a modern computer.
Humans were the earliest computers. These "counting persons" were professionals who worked with numbers and were credited with great accuracy. The early computing was manual and involved the use of such counting tools as the abacus and a variety of slide rules.
When adding machines were developed, the man or woman who computed with one of these "rapid" devices, often called the counting machine a computer.
2. CVS is caused by the decreased blinking reflex of the eyes while working long hours focusing on computer screens.
The normal blinking rate in human eyes is about 16–20 blinks per minute and recent studies have shown that the blinking rate decreases to as low as 6–8 blinks a minute for people who are working on computer screens for long periods and this can lead to an irritating condition called dry eyes.
3. A variety of problems related to prolonged viewing of a computer screen.
Short term effects include dry eyes, blurred vision, eye fatigue and excessive tearing.
Long term effects include migraines, cataracts, and visual epilepsy.
Some solutions include keeping reflections and glare to a minimum and to provide a non-fluorescent, uniform light source.
Special lamps are available that maintain the proper light around the monitor and generate light at much higher frequencies than regular light bulbs.
Glasses Can Correct Near and Far, but What About Those Screens in Between?
More people are showing up at eye appointments complaining of headaches, fatigue, blurred vision and neck pain—all symptoms of computer-vision syndrome (CVS), which affects about 90% of the people who have spent three hours or more a day at a computer, according to the National Institute for Occupational Safety and Health.
2. A computerized axial tomography scan which is an x-ray procedure that combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body.
Computerized axial tomography is more commonly known by its abbreviated names, CT scan or CAT scan. A CT scan is used to define normal and abnormal structures in the body and/or to assist in procedures by helping to accurately guide the placement of instruments or treatments.
The procedure was used first in 1972 to study the brain and is a painless and noninvasive procedure that does not require any special preparation. It is considered to be 100 times more sensitive than conventional radiography or X-rays.
As well as being essential for the study of the brain, CT scanning is considered to be invaluable in investigating diseases of any part of the body. It is particularly useful for locating and imaging tumors, and for guiding the operator who is performing a needle biopsy.
A man has such a fear of computers that he imagines that a computer is trying to attack him.
2. Someone who performs the computations entering into astronomical and other problem.
3. The procedure of calculating and determining something by mathematical or logical methods: "Computists are those who study and practice computing that includes programming, multimedia activities, gaming, and other computer activities."
2. The medieval name for a set of tables for practically calculating astronomical occurrences and the movable dates of the calendar: "The calculation of the date of Easter in the Christian calendar is the computus which has been used for this procedure since the early Middle Ages because it was one of the most important computations of the age."
