Study Notes
Personal Area Network (PAN)
- Technologies used include Bluetooth (up to 10 meters), Wi-Fi (up to 100 meters), and Near-field communication (NFC, up to 4 centimeters).
- Benefits include convenience for connection and file sharing, mobility for internet access anywhere, and enhanced security compared to public networks.
- Limitations involve restricted range, susceptibility to interference from devices like microwaves, and potentially higher costs.
Local Area Network (LAN)
- LAN connects devices within a limited area, such as homes, offices, or schools.
- Typically used for connecting personal computers, printers, and various devices.
- Can be implemented as either a wired or wireless network.
Tree Topology
- Tree topology combines characteristics of star and bus topologies.
- Disadvantages include a single point of failure, high costs associated with central devices, and lower security due to data interception possibilities.
Hybrid Topology
- Combines two or more basic topologies to maximize benefits and minimize weaknesses.
- Frequently used in large networks requiring scalability, reliability, and security.
- Examples include star-bus, mesh-star, and tree-mesh topologies.
Network Devices
- Hardware components that connect devices to the network and facilitate data flow.
- Common network devices include access points, modems, hubs, switches, and routers.
Access Point (AP)
- An AP creates a wireless network, connecting devices to the internet without cables.
- Typically linked to a wired network like a router or switch.
- Can be indoor or outdoor, with indoor units serving homes/businesses and outdoor for larger public areas.
- Types can be standalone (easy to set up) or managed (remotely configured).
Benefits of Access Points
- Provide wireless internet access for devices, enhancing convenience.
- Flexibility in placement improves coverage in hard-to-reach areas.
- Security can be enhanced through encryption and configuration to safeguard data.
Drawbacks of Access Points
- Limited range can restrict coverage within buildings.
- Susceptible to interference from other wireless devices, affecting performance.
- Risks of hacking necessitate strong security measures to protect the network.
