Slide 2: 

What is a Network ? A group of two or more computers connected together First network of the world : ARPANET Used for data and voice signal transfer

Slide 3: 

First Network of world: ARPANET Stands for Advanced Research Project Agency Network Developed in 1969 for US Defence Used FTP for message transfer service

Slide 4: 

What is Networking? Practice of linking one or two computers Done with both Hardware & Software Used for Data Centralization, Sharing CD ROM, Using high bandwidth with low bandwidth

Slide 5: 

Components a Network Sender/Receiver Sender/Receiver Medium

Slide 6: 

Classification of Networks

Slide 7: 

Types of Networks Confined to small area like school One is server and others are workstations Used for data, voice transfer

Slide 8: 

Types of Networks Connects geographical areas like cities Satellites uplinks are used Connects local network to global network

Slide 9: 

Types of Networks Connects two or more LANs but within boundaries of city Multiple Routers, Switches are used Mostly used in Local Libraries and Govt. Agencies

Slide 10: 

Types of Networks Connects two or more LANs Just limited to a certain geographical area like college campus

Slide 11: 

Network Topologies

Slide 12: 

Network Topologies Single device, at times device called dumb terminal is connected to the server Devices operates on files from server and returns them back after completing task

Slide 13: 

Network Topologies All devices are connected to a common cable called trunk Maximum segment length of cable is 200 m Maximum of 30 devices per segment

Slide 14: 

Network Topologies Each device is connected to a central device called hub through cable Data passes through hub before reaching destination

Slide 15: 

Network Topologies Devices are connected in a closed loop All devices have equal access to media Device waits for its turn to transmit

Slide 16: 

Network Topologies Used in WANs to interconnect LANs Every device is connected to every other device Use routers to determine the best path of communication

Slide 17: 

Network Topologies Connects groups of star networks Devices are wired to root hub Root hub is connected to second level devices Lowest level devices are smaller computers

Slide 18: 

Network Topologies Combines two or more different physical topologies Commonly Star-Bus or Star-Ring Star-Ring uses Multi-station Access Unit (MAU)

Slide 19: 

Transmission Media

Slide 20: 

Transmission Media Consists of solid copper core surrounded by an insulator mainly PVC Less prone to interference(internal & external)

Slide 21: 

Transmission Media ) Shielded Cables Unshielded Cables RJ 45

Slide 22: 

Transmission Media Consists of centre glass core surrounded by cladding Electrical signals are converted into light signals A phenomenon called as total internal reflection is used for transmission LED or laser is used to transmit signal

Slide 23: 

Networking Devices

Slide 24: 

Networking Devices

Slide 25: 

IP Address Unique address of a computer Routers also have IP address Managed & created by Internet Assigned Numbers Authority IP address-32bit number(4 octet)

Slide 26: 

How to fill IP Address ? Video in queue

Slide 28: 

MS Windows Server 2k3 Introduced on April 2003 Used for centralized security and management Main features: DHCP Server DNS Server
