IP address in dotted form and binary entry

Communicating more than one computer between multiple IT network.
To some intermediary device (eg router) could forward a "package" from one network to another, it must have the basic information as well as the route through which to forward the packet to the destination.

A computer user or application that uses the IPv4 address see four decimal numbers separated by a dot.


However, the process that takes place in the computer and applications that use the IP address seen as binary code. Each of these numbers is written in binary form and as such travels from source to destination (through some sort of media ie. Copper wire, by radio waves or fiber optic cables. For example, when you press a key on the keyboard, the computer operating system receives an electrical impulse, and these impulse is converted into ones and zeros that. bits.
These bits are a combination of Arab (or Indian origin for) the numbers of zeros and ones (1 and 0). It would be too much to explain and now it does not mean much to you ;-)

Thus, an IP address, eg. 192.168.1.65 in binary form looks like this
11000000.10101000.00000001.01000001

Why are these binary numbers (ones and zeros) are arranged just like that, you should know the 'number system and the weight value' in it as well as converting binary numbers to decimal and vice versa. More about binary numbers, see the link (http://en.wikipedia.org/wiki/Binary_number)

IMPORTANT: It is desirable to learn to convert a binary number to decimal and vice versa (and do not forget to hex, you will need in the future). Of course, a program for calculating IP Subnet (IP range) addresses is a welcome like IP Calculator.

It is also important that you know
Data transfer in IT network is made packages and is divided into three packet transfer mode: Unicast, multicast, and broadcast.

- In Unicast transmission of one packet was sent from source to destination on the network. The source node addresses the packet by using the address, which will be at the destination, then the packet is sent to the network, and finally to the destination.
- Multicast data transmission consists of a single data packet that is copied and sent to specific subsets of devices on the network. Source package addressed using a multicast address and then copies the packet and sends a copy of each node (user) that is part of the multicast address.
- Broadcast transmission of data consists of the single data packet that is copied and sent to all nodes that are in the network. Then it uses a broadcast address, and then copies the package to be sent to all users on the network. Let's go to the next page tutorial.
