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
