This presentation provides an overview of data communication and networking. It introduces the group members, presentation topic, and defines data communication as the exchange of data between two devices via transmission. It discusses the characteristics, components, transmission modes (simplex, half duplex, full duplex), transmission media (coaxial cable, fiber optic cable, twisted pair cable), signal types (analog, digital), network topologies (mesh, star, bus, ring), and network types (LAN, MAN, WAN). The presentation is delivered by multiple group members, each providing details on several topics.

10. Overview
• Types of transmission?
• What is the simplex?
• What is the Half duplex?
• What is the Full duplex?

11. Transmission Mode .

12. Simplex
• simplex communication
is a communication
channel that sends
information in one
direction only...

13. Half Duplex
• Half-duplex data
transmission means
that data can be
transmitted in both
directions on a signal
carrier, but not at the
same time..

14. Full Duplex
• Full-duplex data
transmission means
that data can be
transmitted in both
directions on a signal
carrier, at the same
time..

25. Overview
• Characteristics of Topology ?
• What is the Mesh Topology ?
• What is the Star Topology?
• What is the Bus Topology?
• What is the Ring Topology?

26. Characteristics of Topology
Mesh Topology
Star Topology
Bus Topology
Ring Topology

27. Mesh Topology
• A mesh network is a
local network topology
where all nodes
cooperate to distribute
data amongst each
other

28. Star Topology
Star topology is a
network topology wher
e each individual piece
of a network is attached
to a central node..

29. Bus Topology
One long cable that
links all nodes..

30. Ring Topology
A ring network is
a network topology in
which each node
connects to exactly two
other nodes…

32. Overview
• Characteristics of Network?
• What is the Local Area Network(LAN) ?
• What is the Metropolitan Area Network(MAN) ?
• What is the Wide Area Network(WAN) ?

33. Network

34. Local Area Network(LAN)
A network for a single
office, building, or
campus…

35. Metropolitan Area Network
Designed of extend to
an entire of city….

36. Wide Area Network(WAN)
Long distances
transmission a country
a continent the
world…
