• Network interface cards
A NIC or network interface card of Zain company allows
to gain access to the local network or the internet.
Without a network interface card, you cannot send or
receive emails, watch youtube, print to network printers,
or play video games online. However, that's not to say
the the computer is completely useless without it, but It
allows users to connect to each other either by using
cables or wireless. For example, Zain NIC can be picked
up for about 15 sr on average for 4G from your local best
