AP Computer Science Principles: Network Topologies, IP addresses, Network Hardware

A good balance between reliability and cost

High performance in all conditions.

All devices connect directly to each other.

Scalability is limited to small networks.

Star topology uses a central hub.

Mesh topology includes multiple paths.

Bus topology connects all computers along one wire.

Tree topology is a branched structure.

IP addresses can't be changed

IP addresses are used to identify a device on the Internet

IPv4 addresses consist of 32 bits

IPv6 addresses consist of 128 bits

Stores data for backup purposes.

Provides internet access to users.

Directs data packets between devices on the same network.

Connects different networks together
