Advanced networking concepts pdf

Subtypes are defined as the media standards. The Ethernet defines the standards for the wired media. The IEEE Protocols enable communication between two or more end devices. A protocol is a set of predefined rules that specifies standards for a particular stage or all stages of the communication. Both models divide the entire communication process into logical layers. Further, they explain how the protocols work in each layer to enable the communication process. A networking device works between the end devices.

It controls and forwards the flow of data. Based on the functionalities, a networking device can be categorized into three types; forwarding device, connecting device, and securing device. A forwarding device forwards the data. This device usually has multiple ports which are used to connect more than two end devices in a single network.

Hub, bridge, and Ethernet switch provide this functionality. A connecting device connects two or more different types of media and protocols. If two end devices are located in different logical networks or connected through the different types of media, they need a connecting device to exchange the data. Router and Multilayer switch provides this functionality. A securing device secures the data from unauthorized access.

When a data packet arrives in it, based on pre-defined rules it performs security checks and takes the forwarding decision. Common devices which provide this functionality are the Firewall and NAT.

After learning the essential components of the network, this should be your next topic. Computer networks are mainly categorized based on the geographical location, access types, and relationship between end devices. Based on allowing users to access network resources, the network is classified into three types; Intranet, Extranet, and the Internet. An Intranet is a private network.

In this network, external users are not allowed to access the network resources. An Extranet is also a private network. But in this network, after proper authorization, external users are allowed to access a small portion of the network.

The Internet is the public network. Any user can connect with this network. In peer to peer network, all end devices have equal rights. You can change your ad preferences anytime. Next SlideShares.
