1

LAN

A data network that is restricted to a single geographic location and encompasses a relatively small area (e.g. office building, school).

2

PAN

A LAN created to share data among personal devices

3

WPAN

Technologies involved in connecting devices in very close proximity to exchange data or resources, usually through the use of Bluetooth, infrared, or NFC

4

Ad hoc Wireless Networks

Networks that have devices connect to each other directly, not through a wireless access point

5

WAN

A network that spans more than one geographic location, often connecting separated LANs; Slower than LANs; Often require additional and costly hardware such as routers, dedicated leased lines, and implementation procedures

6

MAN

A WAN that is confined to a certain geographic area, such as a university campus or city; Smaller than a WAN and almost always bigger than a LAN; Utilize an ISP or telco provider

7

SCADA/ICS

Supervisory Control and Data Acquisition & Industrial Control System; The operating systems associated with remote equipment; Often used to gather and analyze data from remote systems in real time

8

Peer-to-Peer Network

A decentralized network model offering no centralized storage of data or centralized control over the sharing of files or resources

9

Client/Server Network

Allows for centralized network management of all network services, including user management, security, and backup procedures

10

Star Topology

All computers and other network devices connect to a central device called a hub or switch; The easiest to expand in terms of the number of devices connected to the network

11

Bus Topology

Uses a trunk or backbone to connect all the computers on the network

12

Ring Topology

A logical ring in which data travels in a circular fashion from one computer to another on the network

13

Wired Mesh Topology

Incorporates a unique network design in which each computer on the network connects to every other, creating a point-to-point connection between every device on the network; Provides high levels of redundancy and so offers better fault tolerance
