Examples of the first generation computers include ENIAC, EDVAC, UNIVAC, IBM-701, and IBM-650 . These computers were large and very unreliable. They would heat up and frequently shut down and could only be used for very basic computations.
Read moreWhat are the 1st to 5th generation of computer?
In accordance with the methodology for assessing the development of computer technology, the first generation was considered to be vacuum tube computers, the second – transistor computers, the third – computers on integrated circuits, the fourth – using microprocessors, and the fifth generation computers is based on …
Read moreWhich modulation technique is used in 1G?
The first generation mobile systems are based on analog technology. The first technology uses frequency modulation (FM) and frequency division duplexing (FDD), frequency division multiple access (FDMA). The common signalling channels were used in first generation cellular systems.

Each cell had a base station, which used radio signals and a transceiver for communicating with mobile devices. Bade stations were connected to telephone networks. Frequency modulation techniques were used for voice calls by base stations.28 Eyl 2018
Read moreWhich modulation technique is used in 2G?
The technology behind the Global System for Mobile communication (GSMTM) uses Gaussian Minimum Shift Keying (GMSK) modulation a variant of Phase Shift Keying (PSK) with Time Division Multiple Access (TDMA) signalling over Frequency Division Duplex (FDD) carriers.
Read moreWhen was 1G launched in India?
The telecom world has seen a new mobile generation roughly every 10 years since the first 1G system was introduced in 1981 . The first 2G system started to roll out in 1992 while the first 3G system first appeared in 2001. The 3G network is several times faster than the 2G one.
