Assume you have a server named
“santa” and a client named “elf”. The
server shares a directory/folder called
“\toys”. Give the windows command
given on the client, to map the above
directory.
net use k: \\santa\toys
Assume you have a unix server named
“santa” and a unix client named “elf”. The
server shares a directory/folder called
“/toys”. Give the Unix command given on

empty directory (/turkey) on the client.
mount santa:/toys /turkey

Virtual drive
a logical drive letter that is not physically located
on the system. Used to do drive mappings
between client and server. Like the K: drive in the
class lab. Points to a folder on the server.
DNS
Domain Name Service. A dns server translates
names into ip number and visa versa. This is
useful because most humans who use internet
applications specify systems by using names, but
the tcp/ip packets need to use ip numbers instead.
Thus DNS servers are used to translate.
