Network Types Flashcards
What does a network type primarily refer to?
The size and scope of the network
A network type refers primarily to its size and scope.
- The size of a network can be measured as the number of nodes,
- while the scope refers to the area over which nodes sharing the same network address are distributed
What does a Local Area Network (LAN) primarily describe?
.It does not require a leased telecommunication system to function. Most of the network infrastructure in a LAN would be directly owned and managed by a single organization.
Give examples of LAN:
Home/residential networks—with an Internet router and a few computers, plus mobile devices, gaming consoles, and printers.
Small office/home office (SOHO) networks—A business-oriented network possibly using a centralized server in addition to client devices and printers, but often still using a single Internet router/switch/access point to provide connectivity.
**Small and medium-sized enterprise (SME) **networks—A network supporting dozens of users. Such networks would use structured cabling and multiple switches and routers to provide connectivity.
Enterprise LANs—A larger network with hundreds or thousands of servers and clients. Such networks would require multiple enterprise-class switch and router appliances to maintain performance levels. The term campus area network (CAN) is sometimes used for a LAN that spans multiple nearby buildings.
Datacenters—A network that hosts only servers and storage, not end user client devices.
The term wireless local area network (WLAN) is used for LANs based on Wi-Fi. Open (public) WLANs are often referred to as hotspots.
