How did the first electronic computers of the 1940s and 1950s compare to the modern PCs?
Very slow, big, and hot. On the issue of speed a typical memory cycle took on the order of 100 microseconds although there were both faster and slower machines. On the issue of size and heat until about 1958 practically all computers used vacuum tubes, even the smallest vacuum tubes were at least 3/4 inch in diameter and a couple of inches tall and dissipated several watts of power keeping their cathodes red hot.

Was computers invented for NASA?
No NASA diid not exist until 1959, programable electronic digital computers were invented in the 1940s.
What is the history of the computer in the 20th century?
Alan Turing's work in the 1940s led to the development of modern computers. Computers small enough to be used in homes have been available since the early 1980s.
Did the first computer have internet?
No. The first electronic computers were developed during WWII in the 1940s. ARPAnet, widely considered to be the precursor to the internet, didnt come online until 1969.
What is the meaning of computer?
Prior to the 1940s, computers were humans paid to do computation. Usually they had mathematics degrees but spent all day calculating with manually operated desk calculators.After the 1940s, computers were machines replacing the humans that used to do those jobs. However the best displaced human computers became the programmers of the machines.
When was computer made?
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
When was the electronic computers developed around?
1940s
Was computers invented for NASA?
No NASA diid not exist until 1959, programable electronic digital computers were invented in the 1940s.
Are computers becoming human?
No, modern computers are no more "human" than the computers of the late 1940s when they were first introduced, they are automatic algorithmic machines.Computers prior to the introduction of electronic digital computers in the 1940s were human, because they were humans (usually women as the work was considered largely clerical/secretarial and thus below that of the mathematicians who were usually men) whose job title was "computer", as they did computations.Humans tell computers what to do by programming them. No computer has ever figured out how to program itself.
When did the first computer create?
in the 80's . First electronic computers made in the 1940s.
When was computers first used?
1940s
When were computers first found?
Computers were invented in the early to mid 1940s.
Did they have internet in 1975?
The beginnings of the internet started with the US Department of Defense in the late 60's and early 70's. They used what was called ARPANET for internetworking. ARPANET was decommissioned in 1990. After that, commercial and personal use of the internet began to grow rapidly.

What features were the first home computers limited to?
The first home computers could do anything any other computer could, if you could fit it in their tiny memories.However the first electronic computers in the 1940s and 1950s had exactly the same problem, very tiny memories.
What were the first systems?
Some of the earliest known computer systems include the Colossus, developed during World War II for code-breaking purposes, and the ENIAC, one of the first general-purpose electronic computers built in the 1940s. These systems laid the foundation for modern computing technology.
