Q: What is DNS and why do we use it on
workstations?
workstations?
A: The Domain Name System (DNS) is used to
resolve human-readable hostnames like www.intenseschool.com into
machine-readable IP addresses like 69.143.201.22. The DNS address is configured
on workstations. Windows redirects all domain names to resolve into IP
addresses.

Q: What is a default gateway? What happens if
I don’t have one?
I don’t have one?
A: A default gateway is a routing device
used to forward all traffic that is not addressed to a destination within the
local network or local subnet. If you don’t have a default gateway, it is not
possible to communicate with the network device/host of different networks.
Dial-up internet connections do not require a default gateway though because it
is present in the ISP itself.

other diagnostic purposes. Only specific programs and files with limited driver
support are needed to run the operating system. This will allow you to attempt
to remove viruses, change bad drivers and perform other diagnostic tasks that
cannot be done in Normal Mode.

What is the maximum length of LAN cable for proper communication?
A: There are mainly two types:
1.
Cat 5 (Category 5 where 5 indicates twists
per inch) & Cat 5e (5e indicates 5 twists per inch per pair which leads to
reduced cross talk). Both Cat 5 & 5e are UTP cables that can support up to
100 Mbps.
