| b. | WAN |
17. You have just started a new business. You need to have three to four workstations available for your employees who simply need to share some files and a printer, but you don’t have a large budget. Security is not a major concern, but costs are. What type of network would be the most appropriate for your situation?
| c. | peer-to-peer network |

COMPLETION
1. The three basic functions of a computer are input, PROCESSING, and output.
2. PERIPHERAL components include devices such as printers, disk drives, network cards, and monitors.
3. A FRAME is a packet that has been encapsulated with the source and destination MAC addresses in the header and an error-checking code in the trailer.
4. There are two different network models. One of them, a peer-to-peer network, also is referred to as a WORKGROUP network.
5. MULTITASKING is an operating system’s ability to execute more than one process at a time.
6. Before data is transmitted, it is broken into chunks of data and then encapsulated with the source and destination IP addresses to create a PACKET.
