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.
No NASA diid not exist until 1959, programable electronic digital computers were invented in the 1940s.
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.
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.
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.
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
1940s
The concept of the computer began to take shape in the 1940s with the development of electronic computers. The first programmable digital computer, the Z3, was completed in 1941 by Konrad Zuse. However, the more widely recognized early computers, such as the ENIAC, were developed in the United States in the mid-1940s. Thus, the 1940s is considered the decade when modern computers were invented.

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.

ENIAC stands for Electronic Numerical Integrator and Computer. It was one of the earliest general-purpose electronic computers, developed in the 1940s. In the context of Information and Computer Foundations (ICF), ENIAC represents a significant milestone in the evolution of computing technology, showcasing the shift from mechanical to electronic computing and laying the groundwork for modern computer architecture. Its design and implementation highlighted the potential of computers for complex calculations and data processing.
The Electronic Age of computers is marked by several key inventors and innovations. Notably, John Presper Eckert and John Mauchly developed the ENIAC (Electronic Numerical Integrator and Computer) in the 1940s, which is considered one of the first general-purpose electronic computers. Additionally, figures like Alan Turing and Claude Shannon made significant contributions to computer science and information theory during this era. Their collective work laid the foundation for modern computing technology.
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.
