Study Notes
Network Basics
- A switch connects to a Metropolitan Area Network (MAN) used in areas with poor over-the-air television reception.
- A Wide Area Network (WAN) spans a large geographical area, often a country or continent.
Network Types
- A subnet is a network that connects to other networks.
- A Virtual Private Network (VPN) provides flexible reuse of network resources.
- An Internet Service Provider (ISP) connects to other networks that are part of the Internet and can be a subnet operator.
Network Communication
- A routing algorithm decides which path to use in a network.
- A forwarding algorithm decides where to send a packet next.
- A protocol is an agreement between communicating parties on how communication proceeds.
- Peers are entities comprising corresponding layers on different machines.
- A protocol stack is a list of protocols used by a system, one protocol per layer.
Network Models
- The client-server model is widely used and forms the basis of much network usage.
- Peer-to-peer communication allows individuals in a loose group to communicate with each other.
Network Security and Issues
- Network neutrality argues against differentiating communications based on content or source.
- DMCA takedown notices are automated systems that search for copyright infringement on peer-to-peer networks.
- Phishing messages masquerade as originating from a trustworthy party, leading to identity theft.
Network Technologies
- Broadcast and point-to-point are two types of transmission technology in widespread use.
- Internetwork connects two or more networks, and Interplanetary Internet connects networks across space.
- Personal Area Networks (PANs) let devices communicate over a short range.
- Bluetooth is a short-range wireless network technology.
Local Area Networks
- A Local Area Network (LAN) is a privately owned network operating within and nearby a single building.
- Ethernet is the most common type of wired LAN.
- Access Points (APs) relay packets between wireless computers and the internet.
Network Pioneers and History
- Len Kleinrock was a pioneer of the theory of packet switching.
- The software was initially split into two parts: subnet and host, with four nodes: UCLA, UCSB, SRI, and University of Utah.
