The Online Etymology Dictionary gives the first attested use of computer in the 1640s, meaning ‘one who calculates’; this is an “agent noun from compute (v.)”. The Online Etymology Dictionary states that the use of the term to mean “‘calculating machine’ (of any type) is from 1897.”
What were computers called before they were called computers?
Early personal computers – generally called microcomputers– were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
What was the first computer called by?
Electronic Numerical Integrator and Computer
The first computer that was Turing-complete, and that had those four basic features of our current computers was the ENIAC (Electronic Numerical Integrator and Computer), secretly developed by the US army and first put to work at the University of Pennsylvania on 10 December 1945 in order to study the feasibility of …
What was the first computer who invented it and when?
The first computer that resembled the modern machines we see today was invented by Charles Babbage between 1833 and 1871. He developed a device, the analytical engine, and worked on it for nearly 40 years. It was a mechanical computer that was powerful enough to perform simple calculations.
Where does the word compute originate from?
The word ‘compute’ comes from the Latin word computare, meaning “arithmetic, accounting, reckoning”.
When was the word computer first used and what its original meaning?
computer (n.) Meaning “calculating machine” (of any type) is from 1897; in modern use, “programmable digital electronic device for performing mathematical or logical operations,” 1945 under this name (the thing itself was described by 1937 in a theoretical sense as Turing machine).
When was laptop invented?
1981
The first laptop computer available to the public was the Osborne 1. The Osborne Computer Corporation released this model in 1981. It cost $1795 at the time of release. The screen was five inches long and the keyboard was in the lid of the computer.
When was the first computer invented timeline?

How was the first computer invented?
In 1837, Charles Babbage proposed the first general mechanical computer, the Analytical Engine. The Analytical Engine contained an ALU (Arithmetic Logic Unit), basic flow control, punch cards (inspired by the Jacquard Loom), and integrated memory.
When was the first computer introduced?
In 1822, Charles Babbage created the first mechanical computer, which was not really considered to resemble the used computer today. Therefore, the description is below that explains the invention of the first computer.
When was the second computer invented?
The second generation computers were used during 1957-1963. They are also known as transistor computers. The second generation of computers consists of two types of devices, transistors, and magnetic core.
What is the meaning of compute in computer?
To compute is to calculate, either literally or figuratively. Computers do the math for you, faster than humans ever can. You’ll often hear someone say that something “does not compute.” This means it doesn’t add up, it doesn’t make sense.
What is the origin of the word ‘computer’?
But the origins of the term ‘computer’, in particular, are worthy of comment. The word obviously derives from the verb ‘compute’, which is from the Latin for ‘reckon with’ (from the prefix com- and the verb putāre meaning to reckon). But what about the meaning of the word ‘computer’?
What was the first computer in history?
ENIAC (1946) usually is considered the first. Computer literacy is recorded from 1970; an attempt to establish computerate (adj., on model of literate ) in this sense in the early 1980s didn’t catch on. Human computers were in demand in several activities. Financial and accounting.
Was computer a formal job title in the past?
Yes, Computer was a formal job title. Astronomer Henrietta Swan Leavitt (discoverer of Cepheid variables) was originally employed as a computer at $10.50 a week. The job as computer was later outlawed, at least in the United States, and I imagine the usage as a description of a person abruptly ended as a result.
What do you call a person with a computer?
Comput-er obviously refers to a person, because, if it were from the beginning to designate a device or machine, it would probably have been called Comput-or, as in: excavator, transformator, accelerator, resistor, transistor, or again as in not so material objects, but still objects, like multiplicator, divisor and so on.
