Q1 part 2
Network components and functionality.
1. Servers: Servers are the computer systems that hold
programs, shared files, and network (OS) operation
system. Servers give access to networks, there are
different types of servers and single server can provide
heaps of functions. There are print servers,
communication servers, mail servers, fax servers and
many more.
2. Switch: This is the telecommunication device grouped as
computer network components. Switch filter the data
properly and then transmit the data .there are different
ways to use the switch mostly we use switch to connect

a PC or Laptop to router .The switch also look like
modems but switches have heaps of connection ports
and modems comes with two or three ports.
Moreover, .The switch and hubs have same RJ-45 ports.
3. Router: The router is used to connect LAN with an
internet connections .When we have two LAN networks
and we want to share internet connection to other
computers we use a Router. There are two types of
Routers wireless and wired .In simple words, A router is
a network device that used to forwards data between
networks.
4. LAN cable : Lan cable also the part of computer network
components .the LAN cable is also known as Ethernet cable
and data cable .The function of LAN cable to connect devices
to the internet and this cable also used to connect other
devices such as computers ,printers and many more.

IP planning for Sales Group.
Network Address: 192.168.20.0
Broadcast Address: 192.168.20.255
IP range from: 192.168.20.1 to 192.168.20.254

IP planning for Marketing Group.
Network Address: 192.168.20.0
Broadcast Address: 192.168.20.255
IP range from: 192.168.20.1 to 192.168.20.254
IP planning for Admin Group.
Network Address: 192.168.20.0
Broadcast Address: 192.168.20.255
IP range from: 192.168.20.1 to 192.168.20.254

Q 2.
Ans: According to the OSI models data reached to their
destination through 7 OSI layers.
There are seven OSI layers:
1. Physical layer is Layer 1.
2. Data link layer is layer 2.
3. Network layer is layer 3.
4. Transport layer is layer 4.
5. Session layer is layer 5.
6. Presentation layer is layer 6.
7. Application layer is layer 7. (Search Network, n.d.)
The data send process start from layer 7, application layer
place header field which include data such as screen fonts
and size, and then passes the information and data to Layer 6
(presentation layer).Moreover, The presentation data covert
data properly for example text messages converted to ASCII
and then pass data to layer 5 (Session layer).After, The
session layer place layer 5 header data and manage the data
and information flow, and pass the data to Layer 4 (Transport
layer). (OSI layers, n.d.)
After data, Layer 3 handles the routing and the addressing
and check the right direction of data, and pass the data to

layer 2 (data link layer).Moreover, the data link layer setup
links through physical network and convert the data packets
to network frames and then pass data to layer 1 (physical
layer).After that the process is done by physical layer that is
transmission across the media.
There are seven steps that occur in reverse order to send
data to their destination
The fellow chart below showing how the data reached to
their destination through seven layers.

Q2 Part B.
CSMA/CD one of the best protocol that we can use to find
the collision and retransmit the data.
CSMA /CD means carrier sense multiple collision
detection.CSMA/CD works with several steps, the process is
based on typical group conversation. IT is very crucial the
participants speak one by one and do not speak all at once
that can make confusing. Apart from that everyone need to
speak one by one so they can understand communication
properly. (Digital Guide, n.d.)
CSMA/CD is mostly used in networks, repeaters and
hubs .The reason is that these devices run half duplex mode
and all the ports of these devices in the same domain
collision.
Moreover, the packet collisions happen when the
transmission happen from another host at the same time .To
prevent this collisions, CSMA/CD forces the station
transmitting to ensure for the availability of the digital
signals. The flow of the protocol below. (Digital Guide, n.d.)

Q 3.part A
Why IPv6 unavoidable in future technology.
Ans: There is no doubt IPv6 will be unavoidable in
future .IPV6 is most recent version of internet protocol .this
is the more powerful than ipv4 and it was planned to replace
the ipv4 .Moreover, IPv6 have large addressing space and
also other technical benefits .The entire number of ipv6
address is around 7.9×1028 time and ipv4 use 32 bits addresses
and delivers 4.3 billon addresses .As we know that IPV4 also
secure but IPv6 is more secure and encrypts traffic and
