Ccna (200 125)

CCNA(ROUTING & SWITCHING)
Exam Code: 200-125

What is CCNA ?
 CCNA (Cisco Certified Network Associate) is an information
technology (IT) certification from Cisco.
 CCNA certification is an associate-level Cisco Career certification.
 There are now several different types of Cisco-Certified Network
Associate, with "CCNA Routing and Switching" being closest to the
original CCNA focus; other types of CCNA focus on security, cloud,
collaboration, security operations, design, data center technologies,
industrial plants, service providers, and wireless.

through some sort of medium for the
purpose of Communication

TYPES OF DEVICES
Devices are of two types
1- Passive Devices 2- Active Devices
( no need of power/electricity ) (required power/electricity )
15

TYPES OF DEVICES
Active Devices are also of two types
Intelligent (manageable) Non-intelligent (non-manageable)

Netgear Hub
D-Link Hub

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

WHY NETWORK?
To Share Resources e.g. Share Printer,Share Information i.e.
Pictures etc
26

BENEFITS & DRAWBACKS
27
Reduce overall cost
Improve Performance

NETWOR TYPES
29
Geographically Network is divided into two main types
1- Local Area Network (LAN) 2- Wide Area Network (WAN)

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

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

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

WHAT HAPPENDS IF SPEED MISMATCH ?

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

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

NETWORK TOPOLOGIES
Physical Layout of Network is called Topology
Selection of topology depends on followings
 COST
 PERFORMANCE (CSMA/CD)(BROADCAST)
 RELIABILITY
36

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

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

DRAWBACKS OF BUS TOPOLOGY
 Cost= low
 Performance = poor
(single collision & Broadcast domain)
 Reliability= zero
39

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

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

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
