Which generation of computer is best?
Fourth and Fifth Generations of computer is best.
How many generations of computer are there?
five computer generations
Generations of Computers Nowadays, generation includes both hardware and software, which together make up an entire computer system. There are five computer generations known till date. Each generation has been discussed in detail along with their time period and characteristics.
What is the features of first generation?
Features of first generation computers: Machines languages were used to instruct the computer. Magnetic core memory was used as primary memory. Electrostatic tubes, Parer tape, punch card, magnetic tape. Punched card, printing devices were used for input/output operations and store the result.
What is first generation computer and its features?
The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and the installations used to fuse frequently.
How are the five generations of computers different?
Each one of the five generations of computers is characterized by a major technological development that fundamentally changed the way computers operate. Most major developments from the 1940s to present day have resulted in increasingly smaller, cheaper, more powerful and more efficient computing devices.
When did the first generation of computers come out?
The period 1940 to 1956, roughly considered as the First Generation of Computer. The first generation computers were developed by using vacuum tube or thermionic valve machine. The input of this system was based on punched cards and paper tape; however, the output was displayed on printouts. The first generation computers worked on binary-coded
What did the second generation of computers do?
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN.
What’s the percentage of computers that run Windows?
Windows has traditionally dominated the personal computer world, running, by some estimates, more than 75 percent of all personal computers . Beginning in the early 2000s, Windows dominance has lessened with the growth of the Linux and Mac operating systems.
