Connectivity of different devices
through some sort of medium for the
purpose of Communication

15. TYPES OF DEVICES
Devices are of two types
1- Passive Devices 2- Active Devices
( no need of power/electricity ) (required power/electricity )
15
16. TYPES OF DEVICES
Active Devices are also of two types
Intelligent (manageable) Non-intelligent (non-manageable)
16
Netgear Hub
D-Link Hub
17. TYPES OF DEVICES
Network Devices
End user Networking Security
Pc/Laptop Routers Firewall
IP Phone Switches ASA
IP Camera Access Points IDS/IPS

25. UTILIZATION OF CABLE
1. Same Layer’s devices use cross cable
2. Different Layer’s devices use straight cable
3. Console connectivity require roll over cable
4. T-shoot require loopback

26. WHY NETWORK?
To Share Resources e.g. Share Printer,Share Information i.e.
Pictures etc
26
30. Local Area Network (LAN)
Local Area Network
A network with-in a small House, Office
or Campus without using any Public
Infrastructure is called Local Area Network.
It is also called Private-Network
It is a low cast network
It is a high speed network
Normally considered Layer-2 Network
30
31. Wide Area Network (WAN)
Wide Area Network
A large organizational Network which has no limits
Built using public infrastructure is called
Wide Area Network
It is also called Public-Network
It is a high cost network
It is a low speed network
Normally considered Layer-3 Network 31
32. ETHERNET STANDRED
IEEE 802.3
This is generally a local area network (LAN) technology with some wide
area network (WAN) applications. Developed by Institute of Electrical
and Electronics Engineers (IEEE).
Ethernet = 10Mbps
Fast Ethernet=100Mbps
Giga Ethernet=1000Mbps
32
34. TYPES OF COMUNICATION
Sharing of resources between devices is called Communication.
There are three types of communication
Unicast (one to one )
Multicast (grouped)
Broadcast (one to all)
34
35. MODES OF COMUNICATION
There are two modes of communication
Simplex Mode
(Sender sends only, Receiver receives only)
Half Duplex
(one can send or receive at same time)
Full Duplex
(one can send & receive at same time)
35
36. NETWORK TOPOLOGIES
Physical Layout of Network is called Topology
Selection of topology depends on followings
COST
PERFORMANCE (CSMA/CD)(BROADCAST)
RELIABILITY
36
37. TOPOLOGY TYPES
There are three main types of topologies
LAN TOPOLOGIES (bus/star/ring/mesh)
WAN TOPOLOGIES (hub & spoke/mesh)
WLAN TOPOLOGIES(Infrastructure / Ad-hoc / mesh)
37
38. BUS TOPOLOGY
A bus topology uses a single
backbone cable
that is terminated at both
ends.
All the hosts connect directly
to this backbone
38
39. DRAWBACKS OF BUS TOPOLOGY
Cost= low
Performance = poor
(single collision & Broadcast domain)
Reliability= zero
39
40. RING TOPOLOGY
Uses a Token to pass information
Token is attached to the Message by
the sender
If the Recipient computer identifies
the Token as its own, then it will
process the information.
40
41. STAR TOPOLOGY (HUB)
Hub works as a center device
Single point of failure
More cable required
Hub always broadcast
Hub is the none intelligent device
Hub share the bandwidth
Hub offers one collusion domain
Hub based network are physically star but logically bus 41
42. STAR TOPOLOGY (SWITCH)
Most common type today used. All computers
are attached to a switch less collisions & most
efficient
Every port of the switch is on separate collision
Switch builds cam table
Switch broadcast / multicast / unicast
Switch offers one broadcast domain
But single point of failure
