Full form of RAID (Redundant Array of Independent Disks)
It is the way of storing the same data in different places
(thus, redundantly) on multiple hard disks.
RAID levels
RAID 0 (block-level striping without parity or mirroring)
RAID 1 (mirroring without parity or striping)
RAID 2 (bit-level striping with dedicated Hamming-code
parity)
RAID 3 (byte-level striping with dedicated parity)
RAID 4 (block-level striping with dedicated parity)
RAID 5 (block-level striping with distributed parity)
RAID 6 (block-level striping with double distributed parity)
============================================================
DNS, full form (Domain Name System)
It translates domain names meaningful to humans into the
numerical identifiers <IP> associated with networking
equipment for the purpose of locating and addressing these
devices worldwide.

DHCP allows a computer to be configured automatically for
IP address.

IP Classes

number, called an IP Address.

PROTOCOL :
"Protocol" usually refers to a set of rules that define an exact format for communication between systems. For example the HTTP protocol defines the format for communication between web browsers and web servers, the IMAP protocol defines the format for communication between IMAP email servers and clients, and the SSL protocol defines a format for encrypted communications over the Internet.
