b) Reason for including the plus sign (+) in the search text in a search engine:

c) Difference between LAN and WAN:

Local Area Network (LAN) is a computer network that connects devices within a limited geographic area, such as a single building or a group of buildings. Devices in a LAN are connected to each other directly or through a switch.

Wide Area Network (WAN) is a computer network that connects devices across a large geographic area, such as across cities, countries, or even continents. Devices in a WAN are connected through routers and other networking equipment, and often use public or leased communication links.

Here is a simple diagram to illustrate the difference between LAN and WAN:
