That is a difficult and well debated question. It depends what you define as a computer. Electronic computers only go back to the 1940s. However there were many mechanical computing devices for centuries before that. If you want to really go back you can say that the first computer was a simple device invented over 5000 years ago and still in use in many schools today, namely the abacus.
First generation computers were built with vacuum tubes. The capabilities were about the same as that of modern computers, except limited by very small memories and slow speed. Typical first generation computer memory cost from $2 to $20 per byte equivalent, whereas today's computer memory costs less than a micro-penny per byte.
The history of computer is divided into 5 generations. First Generation 1941-1956 Second Generation 1956-1963 Third Generation 1964-1971 Fourth Generation 1971- Present Fifth Generation Present and Beyond

Yes you can! The first time you attach your iPod to itunes you register it and then every time you attach it in, it will have your songs that play on your iPod
The third generation of computers, which emerged in the 1960s and 1970s, first utilized multiprogramming. With the development of mainframes and time-sharing systems, these computers were capable of running multiple programs simultaneously, sharing the CPU's processing time among different tasks.

generation time
I have never heard anyone call it that, but it is about as reliable as any other electronic device. Each computer generation has improved the reliability over the preceding generation, as have other electronic devices produced in the same time period.
A generation is a group of people born at roughly the same time. A contemporary is someone living in the same time period.
A computer time line is what updates have happened to the computer for any period of time

Most first generation computers had no operating system. When they did, it was usually just something called a Batch Monitor, all it did was sequence through several jobs one at a time that had been submitted in a batch. The computer companies saw no need for any form of operating system, so the machine's users had to write them all themselves. It was not until the second generation computer that computer companies supplied operating systems for their computers and the earliest of these were simply adaptations of operating systems written by users of first generation computers with a few extensions.
The spirit of the time; the taste and outlook characteristic of a period or generation.
