The first generation computers used vacuum tubes for circuitry and magnetic drums for memory. Key Points. Generation in the computer is nothing but the evolution in different forms of computer.; Every time new hardware technology is used.; Each generation involves different hardware and software components that make it form a Computer system.
Magnetic Drum: A magnetic drum is a magnetic storage device used in many early computers as the main working memory, similar to how modern computers use random access memory (RAM) cards. In some cases, magnetic drum memory was also used for secondary storage. It is basically a metal cylinder that is coated with a magnetic iron-oxide material ...
The Magnetic Generator operates and is able to generate power due to interaction of permanent magnets with bifilar coils and an emerging electromagnetic force between them. The magnets and coils are directed towards each other to create torque on the rotor. This composition of the drum of the generator is designed in order for rotor to rotate ...
First Generation of Computer– Vacuum Tubes. The first generation of computers started in 1940 and lasted till 1956. The main feature of this generation is the use of vacuum tubes in circuits and magnetic drums for memory. The vacuum tubes are also referred to as thermionic valve machines. They were large and produced a large amount of heat.
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.
The vacuum tubes technology was used by the first generation of the computers, which was invented by Lee De Forest in 1906. The vacuum tube inventor named Lee De Forest, was an electrical engineer. For the memory and taking up the big rooms, the vacuum tubes were used on the first generation of a computer for the magnetic drums and the circuitry.
punch cards and magnetic tapes were also used while in the second generation, instead of vacuum tubes, transistors were used as internal components. on comparing the size, they were much larger than first-generation computers and hence named as mini computers. they were 10X times better and faster than that of first-generation.
second generation. replaced magnetic drums -> information is available instantly magnetic disk second generation. replaced magnetic tape -> in magnetic tape, data had to be accessed in linear sequence as it was written, but with magnetic disk data could …
The second generation of computer was developed from 1959 to 1965. Mainly transistors were used in the 2nd generation computer. In 1947, Bell Labs invented the transistor but it was not seen to have widespread use in computers until the late 1950s. Second-generation computers were cheaper, consumed less electricity, small in size, and faster ...
The first generation of computers used vacuum tubes as circuitry and magnetic drums for memory. These computers had the capacity to store less information. There was another disadvantage of these computers: large cooling systems required. It was very expensive to operate. As a result, the use of such inefficient materials, there were often ...
Answer: The distinguishing feature of second generation computers (1956-1963) is that they used discrete transistors mounted on printed circuit cards. Examples are the IBM 1401, IBM 7090 and 7094, UNIVAC 1107, PDP-1 and 8. All speeds below are given in terms of …
