TCP, UDP, ARP, PING and Domain Description

TCP AND UDP

TCP

The TCP (Transmission Control Protocol) is a connection oriented protocol which helps when a connection gets established and maintained until the application programs at both ends of the computer have finished exchanging messages with each other.

UDP

The UDP (User Datagram Protocol) is one of the simple transport communication layer. It is said to be an unreliable transport protocol but the the most benefit thing about UDP is that it uses the IP services which provides the best delivery services.

Difference Between TCP and UDP

TCP  

• Connection-Oriented
• Require Acknowledgement
• More reliable
• Slow Transmission
• FTP ,HTTP and SMTP are examples

UDP

• Connection-Less
• No Acknowledgement
• Less reliable
• Fast Transmission
• Voice and Video application are examples
  
  

   ARP(Address Resolution Protocol)  

  The Address Resolution Protocol (ARP) is a type of telecommunication protocol is used to map IP anetwork addresses with the hardware addresses used by a data link  Layer.
  
  

  RARP(Reverse Address Resolution Protocol)

  the reverse address resolution protocol is the reverse of ARP where it requests of IP network when a computer only have a physical address available. It is an obsolete telecommunication protocol. 
   

  Ping

  Ping(Packet Internet Groper) is a network utility that is used to test the reachability of an IP Network. Ping operates by sending ICMP (Internet Control Message protocol) packets to the target host and waits for its reply. To ping a host network you need to first go to CMD ,then write ping and the target host IP address like this (ping 10.5.4.3). Then press Enter and wait for the reply.
  
  

  Domain

  In simple words, We can say that logical groupings of computer is known as domain. There are two types of domain:
  
  
  1. Collision Domain 
  2. Broadcast Domain
     

      

     Collision Domain

     A Collision Domain is a group of a network which is connected by either a shared medium or a repeater when Data packets collide with each other when being sent due to the early versions of Ethernet.
     
     

     Broadcast Domain

     A Broadcast Domain is a group of network where all nodes can reach other by broadcasting at the Data link Layer within the same LAN.
