TCP stands for “Transmission Control Protocol”, it is a fundamental protocol within the TCP/IP protocol suite — a collection of standards that allow systems to communicate over the Internet.  TCP is a  reliable and connection oriented protocol. It also includes error checking, which ensures each packet is delivered as requested. It defines how to establishContinue reading “TCP Protocol”

ICMP (Internet Control Message Protocol) is an error-reporting protocol network devices like routers use to generate error messages to the source IP address when network problems prevent delivery of IP packets

The IPv4 address is a 32-bit number that uniquely identifies a network interface on a machine. An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields that are separated by periods.

UDP (User Datagram Protocol) is an alternative communications protocol to Transmission Control Protocol (TCP) used primarily for establishing low-latency and loss-tolerating connections between applications on the internet. It is a transport layer protocol and is used in number of applications such as Domain Name System (DNS), where queries must be fast and only consist ofContinue reading “UDP Protocol”

The Address Resolution Protocol is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. It is a network layer protocol used to convert an IP address into a physical address. Watch the Video lecture on ARP (click here) YouContinue reading “ARP Protocol”

Pointers is a mechanism through which  u have the power to access memory address. This is the only specific beauty of C that make it stand different from other languages
