3. Network
 Interconnection between two or more than two computers.
 Computer networks can be connected through cables, such as Ethernet
cables or phone lines, or wirelessly, using wireless networking cards that send
and receive data through the air.

5. IPv4 & IPv6
 IPv4 is described in September 1981.
 IPv6 is the sixth revision to the Internet Protocol and the successor toIPv4. It
functions similarly to IPv4 in that it provides the unique, numerical IP
addresses necessary for Internet-enabled devices to communicate. However,
it does sport one major difference: it utilizes 128-bit addresses.
 The IPv4 address space is a 32 bit field. There are 4,294,967,296unique
values.
 IPv6 is short for "Internet Protocol Version 6". IPv6 is the Internet's next-
generation protocol, designed to replace the current Internet Protocol, IP
Version 4.

7. Classes of IPv4
 Class A- 0 to 127
 Class B- 128 to 191
 Class C- 192 to 223
 Class D- 224 to 239
 Class E- 240 to 255

8. Subnet mask
 A subnet mask is a screen of numbers used for routing traffic within a
subnet. Once a packet has arrived at an organization's gateway or connection
point with its unique network number, it can be routed to its destination
within the organization's internal gateways using the subnet number.
 For class A- 255.0.0.0
 Class B- 255.255.0.0
 Class C- 255.255.255.0

9. Represent of Class
 Like in class C
N.N.N.H (Reserve)
192.168.0.0 (Network Address)
192.168.0.1
192.168.0.2
------
192.168.0.255 (Broadcast Address)
Here 192.168.0 is (N)Network Address and H is Host Address.

10. IP

INTERNET NO-INTERNET

11. IP assign

(Dynamic Host Configuration Protocol)

12. DNS
 The Domain Name System (DNS) is a hierarchical decentralized naming system
for computers, services, or any resource connected to the Internet or a
private network. It associates various information with domain names
assigned to each of the participating entities.
