Is it LAN
Yes, you are correct. The type of data communication system that is composed of a group of devices in close proximity is a LAN (Local Area Network).
To arrive at this answer, you can look at the options provided and consider their definitions:
1. CAN (Controller Area Network): This is a type of data communication system used in vehicles to allow various electronic devices to communicate with each other.
2. LAN (Local Area Network): A LAN is a network that connects devices within a limited area, such as a home, office building, or campus. It allows for the sharing of resources and information among connected devices.
3. MAN (Metropolitan Area Network): A MAN is a larger-scale network that covers a larger geographic area, such as a city or a metropolitan area. It typically connects multiple LANs together.
4. WAN (Wide Area Network): A WAN is a network that covers a wide geographic area, such as multiple cities or countries. It is used to connect different LANs or MANs together.
Considering the definitions, we can see that a LAN fits the description of a data communication system composed of devices in close proximity.
