In the 1920s. If that helps at all... :]
Lack of thinking power in computers was a challenge for the scientists. So they are trying for this and there all expectation about fifth generation computers are ARTIFICIAL INTELLIGENCE and EXPERT SYSTEMS. The scientists want the computer like a human being and these are all expectations about fifth generation computers.
The computer was not discovered, it was invented. It was a long process of invention for the computer as we know it today. First generation: (post World War II) Digital computers were enormous, developed mainly in the U.S. and used vacuum tubes. Second generation: (around 1960) Computers then used transistors; these were the first successful commercial computers. Third generation: (late 1960s and 1970s) These were characterized by using integrated circuits and miniaturizing components. Fourth generation: (1974) The microprocessor chip defined these computers, which resemble our computers today.
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
The computer is used all over the place!
the invention of transistor in 1947 provided a substitute for vacuum tubes in the second generation of computers. computers of this period all used magnetic-core storage systems for memory. -IBM 410 -Honeywell 800
There are NO compounds in the Periodic Table. They are all Elements.
There is no such thing as a fourth generation language. Machine code is the first generation (the native language of the computer). Assembly language is the second generation (low-level symbolic language). All high-level (abstract) languages are third-generation. Although some languages claim to be fourth-generation or even fifth-generation, they are meaningless terms used by marketing types that tell you nothing about a language's capability.
The parental generation (P) of plants used in Mendel's research all had the same genotype for the specific traits he studied. This allowed Mendel to observe the patterns of inheritance without any variations in the parental generation.
nope. History reflects all the past we have gone through to get up-to today while the Generation just categorizes the sections of history based on achievement so that we have a clear jump outs to memorize and understand.
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.
Yes, all compounds are molecules, but not all molecules are compounds
