It is like a modern phone line, where several private conversation takes place at one time. Routers: The aim of using a router is to direct data along the most efficient and economical route to the destination device.

Routers connect two or more different networks together, such as an Internet Protocol network. Brouters: It is a combination of both routers and bridge. Brouter act as a filter that enables some data into the local network and redirects unknown data to the other network.

Modems: It is a device that converts the computer-generated digital signals of a computer into analog signals, traveling via phone lines. It determines how a computer should be connected to the Internet and how data should be transmitted between them.

TCP: It is responsible for breaking data down into small packets before they can be sent on the network. Also, for assembling the packets again when they arrive.

IP Internet Protocol : It is responsible for addressing, sending and receiving the data packets over the internet. When we type something in an address bar, our request will be processed to the server.

The server will respond back to us with the request.

The messages are sent and received in small packages. This layer includes two activities Transmitting data to the Network Interface layers Routing the data to the correct destinations So how this happen?

Internet layer packs data into data packets referred as IP datagrams.

It consists of source and destination IP address. Beside this, IP datagram header field consists of information like version, header length, type of service, datagram length, time to live, and so on. The datagram are transported through network using these protocols. They each resemble some function like.

It determines how to route message on the network. Likewise, you will have ICMP protocol. It is responsible for diagnostic functions and reporting errors due to the unsuccessful delivery of IP packets. The ARP or Address Resolution Protocol is responsible for the resolution of the Internet layer address to the Network Interface layer address such as a hardware address.

The image below shows the format of an IP address. It is responsible for providing the Application layer with session and datagram communication services.

TCP is responsible for the sequencing, and acknowledgment of a packet sent. It also does the recovery of packet lost during transmission.

Packet delivery through TCP is more safe and guaranteed. UDP is used when the amount of data to be transferred is small.

It does not guarantee packet delivery.

Network Segmentation Network segmentation implicates splitting the network into smaller networks. It helps to split the traffic loads and improve the speed of the Internet.


Beginners Created: January 1, Size: Sangay Yeshi Downloads: Download the file. I am very like this website to download many books.

PramodYadav at Thanks to this website for the PDF easy download. Osarobo at I am very like this website.Brouters: It is a combination of both routers and bridge.

Networking Fundamentals It is primarily responsible for routing packets across a packet switched network. From the Editor Webster's Ninth defines Companion as "one of a pair or set that accompanies another" and Guide as "one that exhibits and explains points of interest.

WLAN requires additional information in the Layer 2 header of the frame. VLANs enables an administrator to segment networks.
