Yes, according to Sr. Charles Johnson Lebron
Correct. There was NOT an operating system in the earliest days of electronic difital computing. :)
No, early computers ran only one job at a time from the 1940s through most of the 1950s. Operators had to manually set the machine up for each job. The earliest operating systems, introduced in the late 1950s were really "batch monitors" that still ran one job at a time but automatically loaded and started the next job (reducing operator workload and reduced computer idle time between jobs). It was not until the early to middle 1960s that true multitasking operating systems were introduced, allowing multiple jobs to load and run together. Virtual memory and memory protection were added to operating systems starting in the middle 1960s, but were not offered generally until the 1970s.
Absolutely, but those are called analog computers and operate very differently than the way digital computers do.Electronic analog computers long predate electronic digital computers and until the invention of the microprocessor were almost always less expensive than electronic digital computers. In some cases hybrid computers were built composed of a digital computer, an analog computer, and converter circuits so that data could be transferred back and forth between the two computing sections of the machine.The most common type of electronic analog computer was the electronic differential analyzer, but there are many other types that have been built for solving specific classes of problems (e.g. electronic harmonic analyzers, electronic finite element analyzers) via electronic analog means.
Electronic Numerical Integrator And Computer. It could only store 20 variables and its architecture had no similarity to any computer built after it. A complete dead-end as far as computing equipment was concerned.

A digital memory card can be bought from a variety of stores. These include electronic stores, computing stores, large stationary stores and even some large supermarkets.
ENIAC ( Electronic Numerical Integrator And Computer) was the first electronic general-purpose computer and designed to calculate artillery firing tables. It was capable of being reprogrammed to solve a full range of computing problems.

Size ! The earliest computers used to literally fill a room with valves ans switches - the same computing power used in the first room-sized computers can now be found in a digital watch !
