Study Notes
WAN
- A WAN can be owned by individuals, schools, offices, or telecom operators and can be private or public
- WANs are difficult to design and maintain
- WANs offer low Internet speed
- WANs face high propagation delay
- WANs exhibit a lesser fault tolerance
LAN vs MAN vs WAN
- LANs are very easy to design and maintain
- MANs are comparitively difficult to design and maintain
- LANs offer high Internet speed
- MANs offer moderate Internet speed
- LANs face short propagation delay
- MANs face moderate propagation delay
- LANs exhibit better fault tolerance than MANs and WANs
Network Topology Mapping
- Network topology mapping software aids in creating network topology diagrams
- Examples of mapping tools include Datadog live network mapping, Edraw, Lucidchart, Microsoft Visio, etc.
Body Area Networks (BAN)
- Challenges of BAN include security and privacy concerns, interference with other wireless devices, battery life and power consumption, and compatibility issues with different devices
- Examples of BAN include wearable devices, implantable devices, and smart clothing
Personal Area Network (PAN)
- PANs let devices communicate over the range of a person
- A common example is a wireless network that connects a computer with its peripherals
- Bluetooth is commonly used for PANs
- Bluetooth networks use the master-slave paradigm, where the system unit (PC) is the master, talking to peripherals as slaves
Local Area Network (LAN)
- A LAN is a privately owned network that operates within and nearby a single building
- LANs are widely used to connect personal computers and consumer electronics to share resources and exchange information
- LANs are typically used by companies, and are called enterprise networks
- LANs run at speeds of 100 Mbps to 10 Gbps, have low delay, and make very few errors
This quiz covers the basics of computer networks, including the differences between Local Area Networks (LAN), Metropolitan Area Networks (MAN), and Wide Area Networks (WAN). It is based on Lecture 7 of the Computer Networks 1 course.
