Computer Networks

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and network configuration to clients. FTP is for file transfers, RPC enables remote procedure calls, and DNS resolves domain names to IP addresses.

ICMP is not a routing protocol - it's used for error reporting and network diagnostics (like ping). OSPF, RIP, and EIGRP are all routing protocols that determine optimal paths for data packets through networks.

EIGRP stands for Enhanced Interior Gateway Routing Protocol, a Cisco-proprietary advanced distance-vector routing protocol. It's an enhancement of IGRP (Interior Gateway Routing Protocol), not "Emerging" or "Emergent".

SSL (Secure Sockets Layer) is a standard security technology for establishing an encrypted link between a server and a client. The link ensures that all data passed between the web server and browser remains private and integral.

FTP stands for File Transfer Protocol. It is a standard network protocol used for the transfer of computer files between a client and server on a computer network. 'Fake' and 'Truncate' are incorrect terms in this context.

A protocol is a standardized set of rules and conventions that govern communication between devices on a network. In the context of the internet, protocols like HTTP, FTP, and TCP/IP define how computers exchange data reliably. Option A refers to transfer time, which is a performance metric, not a communication standard. Option C refers to email attachment size, which is unrelated to protocols.

IANA (Internet Assigned Numbers Authority) is the organization that coordinates the global allocation of domain names and IP addresses. IANA maintains the root zone of the Domain Name System (DNS) and coordinates country code top-level domains (ccTLDs). While individual domain names are registered through domain registrars, IANA operates at the top level of the domain registration system.

SMTP correctly stands for Simple Mail Transfer Protocol. It is the standard protocol for email transmission across the internet, working on port 25 by default. The protocol handles sending emails from a mail client to a mail server or between mail servers.

The ISO OSI (Open Systems Interconnection) model is specifically designed for network environments to standardize communication between different systems and protocols. It's not relevant for standalone PCs that don't participate in network communication. The model provides a framework for network protocol development and implementation.

FTP stands for File Transfer Protocol, a standard network protocol used for transferring files between a client and server on a network. File Transport Protocol, Form Transfre Protocol, and File Transfer Program are incorrect.

The Transport Layer (Layer 4) provides reliable, end-to-end communication services in the TCP/IP model. It handles error detection, flow control, and ensures data arrives correctly and in order through protocols like TCP and UDP.

The Transport Layer specifies protocols like TCP (reliable, connection-oriented) and UDP (unreliable, connectionless). TFTP uses UDP but is an Application layer protocol, while DNS operates at the Application layer and can use both TCP and UDP for transport.
