•
Network:
is basically all the components (H/W &
S/W) involved in connecting computer across
small and large distance
•
Importance of Networks:
Easy access and sharing of information
Sharing of expensive devices and network
resources
Modern Technologies (IP telephony, Video
on Demand, ….etc)
Networking Technologies
10
Network components
•
Network has three main components
Computers
(servers and hosts)
-
Source of applications (network aware applications)
-
ex: HTTP (Hyper Text Transmission Protocol),
FTP (File Transfer Protocol),
SNMP (Simple Network Management Protocol)
Telnet
Network Devices
-
Devices that interconnect different computers together
-
ex: Repeaters, hub, bridge, switch, router, NIC and modems
Connectivity
-
Media that physically connect the computers and network devices
-
ex: Wireless and cables
11
Network Types
•
LAN
(Local Area Network):
It is a group of network components that work
within small area
•
MAN
(Metropolitan Area Network):
It is a group of LANs that are interconnected
within small area
•
WAN
(Wide Area Network):
It is a group of LANs that are interconnected
within large area
12
Network Topologies
•
Topology:
How devices are connected together
Physical Topology:
It describes how devices are physically cabled
Logical Topology:
It describes how devices communicate across
physical topology ex. unicast , broadcast , multicast
13
Reference Models
-
describe data transfer standards
-
a framework (guideline) for network
implementation and troubleshooting
-
divides complex functions in to simpler
components
-
Reference model types :
-
OSI
-
TCP/IP
