The correct answer is: A. Main frames
A single bus structure is a type of computer architecture in which all of the components of the computer are connected to a single bus. This type of architecture is typically found in mainframe computers, which are large, powerful computers that are used for tasks such as data processing and scientific computing.
Mainframe computers typically have a large number of processors, memory modules, and I/O devices. All of these components are connected to the single bus, which allows them to communicate with each other. The single bus structure is a simple and efficient way to connect all of the components of a mainframe computer.
Mini- and micro-computers typically do not use a single bus structure. Instead, they use a more complex architecture that allows for multiple buses. This type of architecture is more efficient for mini- and micro-computers, which typically have fewer components than mainframe computers.
Supercomputers typically use a single bus structure, but they may also use a more complex architecture. The type of architecture that is used in a supercomputer depends on the specific needs of the supercomputer.
Here is a brief explanation of each option:
- Main frames are large, powerful computers that are used for tasks such as data processing and scientific computing. They typically have a large number of processors, memory modules, and I/O devices. All of these components are connected to a single bus, which allows them to communicate with each other. The single bus structure is a simple and efficient way to connect all of the components of a mainframe computer.
- Mini- and micro-computers are smaller and less powerful than mainframe computers. They typically have fewer components than mainframe computers, and they use a more complex architecture that allows for multiple buses. This type of architecture is more efficient for mini- and micro-computers.
- High performance machines are a type of computer that is designed for tasks that require a lot of processing power. They typically have a large number of processors and a lot of memory. High performance machines may use a single bus structure, but they may also use a more complex architecture. The type of architecture that is used in a high performance machine depends on the specific needs of the machine.
- None of the above is not a correct answer.
