Which BEST describes a secondgeneration computer? ( 1 point) the CPU was used for the first time, computers could be owned by the general public, and a GUI was used used operating systems, keyboards, and monitors for the first time, and integrated circuits were used to supply electricity rather limited in functionality, could store programs, and used vacuum tubes to supply electricity high-level programming languages, magnetic tape and disks for storage, and used small transistors to supply electricity
high-level programming languages, magnetic tape and disks for storage, and used small transistors to supply electricity
The correct answer is:
high-level programming languages, magnetic tape and disks for storage, and used small transistors to supply electricity.
The best description of a second-generation computer is: high-level programming languages, magnetic tape and disks for storage, and used small transistors to supply electricity.
To arrive at this answer, let me explain the options and their characteristics:
1. The CPU was used for the first time, computers could be owned by the general public, and a GUI was used: This option describes the features of a fourth-generation computer, where the central processing unit (CPU) was introduced, computers became accessible to the general public, and graphical user interfaces (GUIs) were used.
2. Operating systems, keyboards, and monitors were used for the first time, and integrated circuits were used to supply electricity: This option describes the features of a third-generation computer. Third-generation computers saw the introduction of operating systems, keyboards, monitors, and the use of integrated circuits for supplying electricity.
3. Limited in functionality, could store programs, and used vacuum tubes to supply electricity: This option describes the features of a first-generation computer. First-generation computers were indeed limited in functionality, had the ability to store programs, and used vacuum tubes as their main source of electricity.
4. High-level programming languages, magnetic tape and disks for storage, and used small transistors to supply electricity: This correctly describes the characteristics of a second-generation computer. During the second generation, computers saw the introduction of high-level programming languages, the use of magnetic tape and disks for storage, and the replacement of vacuum tubes with smaller, more efficient transistors for electricity.
Therefore, the best description of a second-generation computer is the one mentioned in option 4.
