The correct answer is: Distributed computing.
Distributed computing is a type of computing where tasks are performed by multiple computers working in coordination. This can be done in a number of ways, such as by using a cluster of computers or by using a grid of computers. Distributed computing can be used to solve problems that are too large or complex for a single computer to handle.
Cloud computing is a type of computing where resources are provided to users on an as-needed basis over the Internet. This can include things like storage, computing power, and software. Cloud computing can be used to save money, to improve efficiency, and to access resources that are not available locally.
Soft computing is a field of computer science that deals with the design and development of computational models that are inspired by the human brain. Soft computing techniques are often used to solve problems that are difficult to solve with traditional methods.
Parallel computing is a type of computing where multiple tasks are performed at the same time. This can be done by using multiple processors or by using multiple cores in a single processor. Parallel computing can be used to speed up the execution of programs.
In conclusion, the correct answer is: Distributed computing.
