Computer Networking Standards

by Vaughn Aubuchon

Here is a brief summary tutorial chart of computer network standards, summarizing the differences between LANs and WANs.

Internet protocols, OSI layers, and other computer network technologies are also summarized. This computer networking tutorial includes a brief glossary of computer networking terms.

Standards Chart

Computer Networking Standards Chart

Computer Network Training -

ISP - Internet Service Provider
LAN - Local Area Network
MAN - Metropolitan Area Network
WAN - Wide Area Network
Gateway - connects different LAN protocols
Bridge - connects 2 Ethernet LANs
Router - connects different LANs, speeds
Switch - directs traffic


LAN Standards
(distances less than 1000 feet)

OSI Layers (Open Systems Interconnect model)
1. Physical - transmits raw data
2. Data Link - checks data, frames, etc.
3. Network - controls subnet, routing
4. Transport - splits data, passes to network
5. Session - manages dialog, synchronizes
6. Presentation - syntax, semantics
7. Application - virtual terminal software

Physical Media
Coax --- Coaxial cable
IR ------ Infra-red
MW --- Microwave
STP --- Shielded Twisted Pair
UTP --- Unshielded Twisted Pair

LAN Protocol Standards
Ethernet --------- 10M
Token Ring ----- 16M
Fast Ethernet -- 100M
FDDI ---------- 100M

WAN Standards
(distances greater than 1000 feet)

FSK ----------- 300-1200
QAM ---------- 2400
DPSK (V32) - 9.6K
DPSK ------- 14.4K
DPSK ------- 28.8K
DPSK (V90) - 56K
ISDN -------- 128K
DSL ---------- 380K
T1 ---------------1.544M
Backplane bus ---- 16M
T3 ------------------ 45M
OC-1 --------------- 52M
ATM, SONET --- 155M
ATM (OC-12) --- 622M
Fiber (OC-24) ---- 1.2G
Fiber (OC-48) ---- 2.4G

Internet Connect Protocols
IP - Internet Protocol

FTP ----- File Transfer Protocol
DNS ---- Domain Name Server
HTML -- Hyper Text Markup Language
HTTP --- HyperText Transmission Protocol
SMTP -- Simple Mail Transfer Protocol
TCP ----- Transmission Control Protocol
telnet ---- guest on large computer
UDP ---- User Datagram Protocol

Telephone Company
Network Protocols

PPP ---- Point-to-Point Protocol
PPPoE - PPP over Ethernet Protocol
SLIP ---- Serial Line Interface Protocol

Although the author has tried to be as accurate as possible, errors and mis-statements are possible.

I could not find a computer network training tutorial like the above. So, I drew this summary diagram of the data network types, to help myself understand the inner workings of data communication network systems. I hope that it helps you.
