If VXUPLVH is written as SURMISE, what is code for SHDVD?

Explanation

  • Here, VXUPLVH is written as SURMISE. By observation we can say that each letter is shifted left by three positions in alphabetical order. Like, three positions left of V is S, three positions left of X is U, three positions left of U is P, three positions left of P is M, three positions left of L is I, three positions left of V is S and three positions left of H is E.
  • Following the same pattern, three positions left of S is P, three positions left of H is E, three positions left of D is A, three positions left of V is S and three positions left of D is A.
  • So, code word for SHDVD will be PEASA.

What is protocol?

Explanation

  • Network protocol outlines conventions for communication between network devices.
  • Computer networking uses packet switching protocols to send and receive messages as packets.
  • Network protocols allow devices to recognize and make connections with each other.
  • Protocol formatting rules specify how data is packed into messages sent and received.
  • For example, Internet Protocol contains a set of most extensively used network protocols.
  • Beside Internet protocol (IP) itself, protocols of higher levels like TCP, UDP, HTTP, and FTP incorporate with IP to provide extra abilities.
  • Likewise, lower-level Internet Protocols take for example ARP and ICMP co-exist with IP.
  • Overall, high-level protocols in the IP unit interrelate more meticulously with apps like web browsers whereas lower-level protocols interrelate with network adapters and all other computer hardware. Apps like web browsers comprise of software libraries that help the high-level protocols to function.
  • Routing protocols are specially made protocols designed precisely for use by network router. Commonly used routing protocols include EIGRP, OSPF, and BGP.
  • Lower level TCP/IP and routing protocols, support is applied in-directly hardware (silicon chipsets) for improved performance.
