Network Protocols Overview

Study Notes

System Network Architecture

FTP (File Transfer Protocol) is used to transfer files between computers.
SMTP (Simple Mail Transfer Protocol) is used to send email.
SNMP (Simple Network Management Protocol) is used to monitor and manage network devices.
TCP (Transmission Control Protocol) provides reliable, ordered delivery of data.
UDP (User Datagram Protocol) provides fast, connectionless delivery of data.
IP (Internet Protocol) is used to route data packets across the internet.
ARP (Address Resolution Protocol) maps IP addresses to physical MAC addresses.
RARP (Reverse Address Resolution Protocol) maps physical MAC addresses to IP addresses.
ICMP (Internet Control Message Protocol) is used for error reporting and network diagnostics.
DNS (Domain Name System) translates domain names into IP addresses.
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices on a network.
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is a method of accessing a shared network medium.
PT (Push To Talk) is a communication method where users press a button to transmit.
WAN (Wide Area Network) connects computers over a large geographic area.
LAN (Local Area Network) connects computers within a small geographic area.
MAN (Metropolitan Area Network) connects computers within a city or metropolitan area.
VPN (Virtual Private Network) creates a secure connection over a public network.
BOOTP (Bootstrap Protocol) helps devices boot up by providing network configuration information.
POP (Point of Presence) is a location where a network provider connects to the internet.
IMAP (Internet Message Access Protocol) is a protocol for accessing email on a server.
TFTP (Trivial File Transfer Protocol) is used for simple file transfers.
NAT (Network Address Translation) allows multiple devices to share a single public IP address.
OSPF (Open Shortest Path First) is a routing protocol that uses a link-state algorithm.
EIGRP (Enhanced Interior Gateway Routing Protocol) is a routing protocol that uses a hybrid algorithm.
ARP (Address Resolution Protocol) maps IP addresses to physical MAC addresses.

Management Information Systems

OSI (Open System Interconnection) is a model that defines the layers of a network architecture.
FDDI (Fiber Distributed Data Interface) is a high-speed network technology that uses fiber optic cables.
ATM (Asynchronous Transfer Mode) is a high-speed network technology that uses fixed-size cells to transmit data.
