A)embedded computers
B)supercomputers
C)mainframes
D)mobiles devices

Accepted Answer

Most major corporations use mainframes for their business activities like billing millions of customers, preparing payroll for thousands of employees, and managing millions of items in inventory. Mainframes are specifically designed for processing large amounts of data and handling complex transactions, making them ideal for such business activities. Embedded computers, supercomputers, and mobile devices do not have the processing power and capacity required for these tasks.

Accepted Answer

A gaming desktop is specifically designed for high-quality audio, video, and graphics performance for sophisticated gaming experiences, both for single-user and multiplayer networked or Internet-based games. Handheld and encapsulated computers do not offer the same level of performance or capability for gaming, and the term "multiplayer" is a broad category that does not necessarily specify gaming as the primary use.

Accepted Answer

The electronic component that interprets and carries out the basic instructions that operate the computer is the central processing unit (CPU), also known as the processor. The control unit and arithmetic unit are sub-components of the CPU, while the motherboard is a hardware component that connects all the other components of the computer together. Therefore, the best choice is C - processor.

A)embedded computers
B)supercomputers
C)mainframes
D)mobile devices

Accepted Answer

Mainframes are large, powerful computers that can handle numerous connected users simultaneously and store tremendous amounts of data, instructions, and information. Supercomputers are also large and powerful but are typically used for complex scientific computations and simulations, rather than for general business purposes. Embedded computers are usually small and designed for a specific, specialized function, such as controlling a machine or electronic device. Mobile devices are small, handheld devices, such as smartphones or tablets, that are used primarily for communication and personal productivity.
