| Term | Full form | Meaning |
|---|---|---|
| OSI | Open Systems Interconnection | Seven-layer reference model |
| TCP/IP | Transmission Control Protocol / Internet Protocol | Internet protocol suite |
| LAN / MAN / PAN / WAN | Local / Metropolitan / Personal / Wide Area Network | Network-scope classifications |
| ARPANET | Advanced Research Projects Agency Network | Historical packet network |
| CRC | Cyclic Redundancy Check | Polynomial error detection |
| ARQ | Automatic Repeat reQuest | Feedback/timer-based retransmission |
| GBN / SR | Go-Back-N / Selective Repeat | Sliding-window ARQ strategies |
| FEC | Forward Error Correction | Recover using coding redundancy |
| CSMA | Carrier Sense Multiple Access | Sense medium before access |
| CD / CA | Collision Detection / Collision Avoidance | Two different medium-access strategies |
| CIDR | Classless Inter-Domain Routing | Prefix-based allocation and aggregation |
| VLSM | Variable Length Subnet Mask | Different subnet sizes within a block |
| ARP / RARP | Address Resolution Protocol / Reverse ARP | Local IPv4-to-hardware mapping / historical reverse mapping |
| DHCP | Dynamic Host Configuration Protocol | Leased network configuration |
| RIP | Routing Information Protocol | Distance-vector protocol using hop metric |
| OSPF | Open Shortest Path First | Link-state interior routing protocol |
| LSA | Link State Advertisement | Topology information advertised in link-state routing |
| UDP | User Datagram Protocol | Connectionless datagram transport |
| SCTP | Stream Control Transmission Protocol | Reliable message-oriented multi-stream transport |
| QoS | Quality of Service | Bandwidth, delay, jitter, loss properties |
| RTT / MSS | Round-Trip Time / Maximum Segment Size | Round-trip delay / TCP data-size parameter |
| HTTP / WWW | Hypertext Transfer Protocol / World Wide Web | Web request-response protocol / linked-resource system |
| DNS | Domain Name System | Distributed hierarchical naming |
| FTP | File Transfer Protocol | Separate file-control and data connections |
| SMTP | Simple Mail Transfer Protocol | Mail submission/relay |
| TTL | Time To Live | Meaning depends on context: IP lifetime field or DNS cache duration |
| ACK / SYN / FIN | Acknowledgement / Synchronize / Finish | TCP control concepts; SYN and FIN consume sequence space |
Do not mix uses of the same acronym: DNS TTL is a cache time; IPv4 TTL is decremented at routers. ALOHA is a protocol name, not an acronym that requires an invented expansion.
