Since a Gigabyte is made of Megabytes, 500 Megabytes times 2, 2(500MB), is equal to one Gigabyte. (1000MB)
UNLESS, it wants the Windows way of storage, because one Gigabyte in Windows terms is actually 1024 megabytes... then it’d be 2(512MB) because 512MB and 512MB equals one windows storage gigabyte.

Answer:
The ping command.
Explanation:
In a network, workstations known as clients, users or nodes are the devices where data is needed or sents from. A server on the other hand, is a device in the network, configured to render a particular service like database, domain name service, web service etc.
When a link from a workstation to a server is down, the workstation looses connection the server. To confirm the connectivity of the link, "ping" the server ip address from the workstation using the command "ping 'server ip address'". This sends echo packets to the server, which is echoed back if there is connectivity.
