Answer: Switch, router, firewall
Explanation:
The function of the switch is to distribute the network to different networks similar in functioning to that of the hub but it performs filtering of the traffic present in the network using various traffic filtering algorithms.
The router whose main function is to route packets across the network is also used to connect between LANs and between LAN and a WAN.
The firewall is typically installed on systems or in servers or in routers with it most important function to filtering the traffic and minimize the packet delivery delay in LANs.
Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Polyphase power systems were independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström, John Hopkinson and Nikola Tesla in the late 1880s.
Answer:
Storing data on the cloud enables access from any location.
Explanation:
Answer:
The output will be as following:-
2
0
0
Explanation:
The function doSomething accepts the argument as reference.So whatever changes are made in the function to the argument the changes will be reflected onto the original arguments.
First the value of x is 2.Hence 2 is printed first.
Then function doSomething is called that changes the value of x from 2 to 0 and then prints it.Hence 0 is printed in the newline.
Then in the main function x is printed again the function changed it's value so 0 is printed.
