Piggy backing is a technique that improves the efficiency of the bidirectional protocols. In this technique data frame and ACK are combined. The major advantage of piggybacking is better use of available channel bandwidth.

Last updated on Nov 22, Humans access information online through domain names, like nytimes. Web browsers interact through Internet Protocol IP addresses. Each device connected to the Internet has a unique IP address that other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as Confusion Points. Consider the resolution of the domain name www. Assume that no resource records are cached anywhere across the DNS servers and that an iterative query mechanism is used in the resolution. The DNS resolver travels to the root server, then forwards to the top-level domain, then forwards to the second level domain, and obtains the IP address from the authoritative DNS server in the iterative query. There are 4-pairs involved in completely resolving the domain name. Additional Information. When a DNS server accepts and uses incorrect information from a host that has no authority giving that information, then it is called. It is the act of disguising a communication from an unknown source as being from a known, trusted source. Therefore when a DNS server accepts and uses incorrect information from a host that has no authority giving that information, then it is called DNS spoofing.

This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Address Resolution Protocol ARP. A logic address is used to send or receive messages in most cases of computers or applications. However, the communication relies upon Physical address i. To make the devices communicate, our intention is to get the MAC destination address. For this purpose, ARP was introduced. This protocol is responsible for translating IP into Physical Addresses. Dynamic mapping is possible by ARP. MAC address is the Data Link Layer that terminates and establishes connections among the physical devices to transfer the data. An IP address is the Network layer that forwards the packets to various routers, and the ARP present works among these layers. It is referred to as the Request-Response protocol.
