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.

Communications
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.
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.
Communications
The bridge carries the Beijing-Shanghai High-Speed Railway.
The SR-71 is a high-altitude, high-speed reconnaissance aircraft. It carries high performance cameras used in spying.
