Study Notes
Network Types
- A Local Area Network (LAN) is a group of computers located in the same general area.
- LANs typically operate at speeds of 100 Mbps or higher.
Network Components
- A Router connects several LANs, other Backbone Networks (BNs), Metropolitan Area Networks (MANs), and Wide Area Networks (WANs).
- A Data Center provides centralized storage, processing, and distribution of data in a network architecture.
- An Internet Service Provider (ISP) provides internet access in a network architecture.
Wide Area Networks (WANs)
- A WAN covers a larger geographic scope, such as cities or countries.
- The purpose of a WAN is to connect multiple LANs and BNs to facilitate communication and data exchange.
Backbone Networks (BNs)
- A BN connects multiple LANs and MANs.
- BNs typically operate at speeds of 100 Mbps to 10 Gbps.
Network Technologies
- The use of network technologies originally developed for WANs is making the distinction between WANs and MANs increasingly blurry.
Internet Exchange Centers (IXCs)
- An IXC is a high-bandwidth hub that connects multiple WAN circuits from different carriers.
- WAN circuits from IXCs typically provide data transmission rates of 1.5 Mbps to 45 Mbps.
Intranets and Extranets
- An intranet is a private network that is not accessible to the general public.
- Examples of information provided on an intranet include employee information, company policies, and internal announcements.
- An extranet is a network that provides access to partners or customers.
- An extranet can provide access to shared resources, such as product catalogs or supply chain management systems.
- Users typically require authentication, such as usernames and passwords, to gain access to an extranet.
- Many universities provide extranets for students, faculty, and staff to access online resources and services.
