IV Поколение ЭВМ
И так, мы ознакомились с
одним из поколений ЭВМ и узнали очень
много нового ;)
1 слайд
IV GENERATION OF COMPUTERS
Large integrated circuits (BIS) served as a new stage for the development of computers. The element base
of computers of the fourth generation is BIS. The rapid development of electronics made it possible to place thousands of semiconductors on one crystal. This miniaturization has led to the emergence of inexpensive computers.

The first minicomputer
The first mini-computer is considered to be the PDP-8
of DEC Corporation. This machine was created to control a nuclear
reactor. But it has become popular at private manufacturing enterprises and in higher educational institutions. Its mass production began in 1965 and by the early 70s the number of these computers exceeded 100,000 pieces. An important transition from mini-computers to micro-computers is the creation of a microprocessor. Thanks to BIS, it became possible to place all the main elements of the CPU on a single chip. The first microprocessor was Intel-4004 created in 1971.

Characteristics of the IV generation computer:
Characteristics of the fourth generation computer.
Multiprocessing.
High-level languages.
Computer networks.
Parallel and
sequential data processing.
5 слайд IPR – (Simple integrated circuits) up to 10
elements
MIS – (Small integrated circuits) up to 100
elements
SIS – (Medium integrated circuits) up to 1,000 elements
BIS – (Large integrated circuits) up to 10,000 elements
VLSI – (Ultra-large integrated circuits) up to 1,000,000 elements
UBIS – (Ultra-large integrated circuits) up to 1,000,000,000 elements
GBIS – (Giga-large integrated circuits) over 1,000,000,000 elements
Integrated circuits can be classified by the number of elements placed on a single chip:

The fourth generation of Soviet computers can include:
EU-1015,
EU-1025, EU-1035, EU-1045, EU-1055, EU-1065. Personal computers,
which have become popular in everyday life: Electronics-85, Iskra-226, EU-1840, EU-1841, EU-1842. The multiprocessor computer "Elbrus" belongs to this generation. Used in production and machine counting stations. Later it was replaced by Elbrus-2. The computing power of this machine, for the fourth generation, was very great. It had about 64 megabytes of RAM, could perform up to 5 million floating-point operations per second. Bus bandwidth up to 120 MB/s.
