A CPU does not calculate anything. A CPU processes information 1s and 0s, on or off, binary code. What look likes calculations are really just a program response. When you open the calculator in any computer and you input 2*2, the person who programed that pice of software basicly sais when you insert 2*2 you should display 4. It does not go like when you insert 2*2 cacluate two times two. It is nothing like that.
When you click somewhere it is programed to react to the position you clicked it does not perform a caculation to figure out what you want.
Computers are capable of high speed calculations, storing data and has access to a wide variety of utility programs that can be used for business matters. Using computers in business can make everyday tasks easier and more efficient.

The speed of data transfer (in KBps or MBps) between computers connected in these networks (Internet, LAN or WAN) will be faster than normal networks. Hence they are called High speed networks. Here high speed Swithing facilitates high speed data transmission.
Computers perform tasks at high speed primarily due to their ability to process vast amounts of data using binary code (0s and 1s) and perform calculations rapidly with their central processing units (CPUs). They utilize advanced architectures and parallel processing techniques to execute multiple instructions simultaneously. Additionally, high-speed memory components, such as RAM and cache, allow for quick data retrieval and storage, minimizing delays during operations. These factors combined enable computers to execute complex tasks in a fraction of a second.
Mainframe computers are connected thru high speed internet or local ethernet having speed probably some mbps. Mainframe computers requires high data bandwidth to transfers data from terminal.

Computers possess several key properties, including speed, accuracy, automation, and storage capacity. They can process vast amounts of data rapidly and perform calculations with high precision. Additionally, computers can operate autonomously to execute tasks based on programmed instructions and can store large volumes of information for easy retrieval. These properties make computers essential tools in various fields, from business to scientific research.
