The Correct Answer
Is "A"
Explanation: This question addresses PPR Competency 009:
The teacher incorporates the effective use of technology to plan, organize,
deliver, and evaluate instruction for all students.
LAN stands for local
area network. A local area network is a short-distance (typically,
less than 500 meters) network used to link a group of computers
together within a building. Ethernet is the most commonly used form
of LAN. A piece of hardware called a hub serves as the common wiring
point,
enabling individual users to communicate through email, to send or
receive files, and to share access to files and data. Each computer
connected
to a LAN is called a node. Personal computers on a school campus are
commonly connected in a LAN, making it easy for the teachers to share
information. Choice A is the correct response. The teachers probably
will use this technology to communicate with each other through email.
The other response choices are not options available through a LAN.
Those capabilities would require a Wide area network (WAN), which can
be made
up of interconnected smaller networks spread throughout a building,
a district, a state, or the world. The Internet itself is considered
a
WAN.
