4. LAN (LOCAL AREA NETWORK) A group of nodes linked together in a small geographical location such as a building or group of buildings.

5. WAN (WIDE AREA NETWORK) A collection of LANs that is used to send data across long distances. Sometimes thousands of miles.

16. THE CLOUD

18. CHARACTERISTICS OF CLOUD COMPUTING On-demand self service Customer can access without human contact Broad network access Can access from any location Resource pooling Services pooled to accommodate use by multiple subscribers Rapid elasticity Subscribers can increase use of resources scaling up and down as needed Measured service Provider meters service for billing and to analyze usage
