Internet Protocol Practice Exam

About Internet Protocol
The Internet Protocol (IP) is a protocol, or set of rules, for routing and addressing packets of data so that they can travel across networks and arrive at the correct destination. Data traversing the Internet is divided into smaller pieces, called packets. IP information is attached to each packet, and this information helps routers to send packets to the right place. Every device or domain that connects to the Internet is assigned an IP address, and as packets are directed to the IP address attached to them, data arrives where it is needed.

Once the packets arrive at their destination, they are handled differently depending on which transport protocol is used in combination with IP. The most common transport protocols are TCP and UDP.

An IP address is a unique identifier assigned to a device or domain that connects to the Internet. Each IP address is a series of characters, such as '192.168.1.1'. Via DNS resolvers, which translate human-readable domain names into IP addresses, users are able to access websites without memorizing this complex series of characters. Each IP packet will contain both the IP address of the device or domain sending the packet and the IP address of the intended recipient, much like how both the destination address and the return address are included on a piece of mail.

Why is Internet Protocol important?
IP is the core of the TCP/IP protocol suite. IP provides the fundamental mechanism using which data is delivered between devices which may or may not be in the same network.
•    Addressing - While sending datagrams, an addressing mechanism is needed to send the datagrams accurately. In order to achieve this, IP uses a technique for host addressing. The addressing of devices (to which the datagrams are delivered) needs to be unique as this system needs to work across networks.
•    Routing - When a datagram is sent from one network to another, which are distant and not directly connected, the delivery is indirect. IP supports this functionality by routing the datagram through intermediate devices (routers). It uses Internet Control Message Protocol (ICMP) and routing protocols like Routing Information Protocol (RIP) and Border Gateway Protocol (BGP) to achieve this.
•    Data Encapsulation - IP provides security to networks by encapsulating the data into an IP datagram. This makes sure it is received and interpreted by the intended recipient.
•    Formatting/Packaging - IP uses a specific formatting and packaging prior to transmission. IP accepts data from the transport layer protocols above it in the OSI layer--UDP and TCP--and passes them to the data layers. This format and package is only decipherable by the recipient.
•    Fragmentation - Since the frame size of each physical and data link network using IP may be different, IP fragments datagrams into pieces, so that they can each be carried on the local network. This helps with network reliability.
•    Reassembly - IP reassembles the datagrams received into the full IP datagram (as they may be fragmented) for the receiving device and passes it on to the higher layers for interpretation.
