Local network
A local network is a computer network connecting devices within a limited physical or administrative area, such as a home, office, or campus.

A local area network is a network that connects devices within a limited geographic area such as an office or building.
- How it is used
- Defines the local scope in which interconnected devices communicate through switches.
- How deep it goes
- Explains physical and Layer 2 boundaries, then applies them to IP addressing, ARP, switching, and default gateways.
- Examples
- Uses office networks, directly connected switches, routed switches, and a PC1-to-PC3 ARP exchange.
- What you can do after
- Understand whether devices share a LAN and determine when traffic must use a router or default gateway.

Fast Python: High performance techniques for large datasets
- How it is used
- Frames local networks as a performance factor when moving data between nodes in clusters or clouds.
- How deep it goes
- Compares network and disk throughput, then motivates a client/server design suited to fast local communication.
- Examples
- Uses a pastebin-style client/server service to illustrate storing and retrieving text over a fast local network.
- What you can do after
- Evaluate how fast local networks can change assumptions about disk access and conventional network communication.
