Networking Fundamentals

A computer network connects two or more computers to communicate.
Each device on a network is called a node.
Nodes can include computers, peripherals, and network devices like routers.

Benefits of Networks

Share high-speed Internet connection.
Share printers and peripheral devices.
Share files.
Facilitate common communications.

Disadvantages of Networks

Network setup and administration.

Data Transfer Through Networks

Data transfer rate (bandwidth) is the maximum data transmission speed.
Throughput is the actual data transfer speed.
Speed is measured in megabits per second (Mbps) and gigabits per second (Gbps).

Network Architectures

Networks are classified by distance:
- Personal Area Network (PAN): Communication among devices close to a person.
- Local Area Network (LAN): Nodes in a small geographical area.
- Home Area Network (HAN): Specific type of LAN in a home.
- Metropolitan Area Network (MAN): Large network covering a city.
- Wide Area Network (WAN): Spans a large physical distance.
Networks are also classified by administration levels:
- Client/server network: Clients request information from a central server.
- Peer-to-peer (P2P) network: Nodes directly communicate with each other.

Classifying Networks by Protocols

Ethernet: Developed by the IEEE (Institute of Electrical and Electronics Engineers).
- Supports both wired and wireless networks.
Backward compatibility: Ability of current devices to use older network standards.

Network Components

Connecting nodes (cables/wireless technology).
Hardware devices for communication (network adapters, NICs, modems, routers, switches).
Software to run the network.

Network Hardware

Network adapter: Integrated adapter (NIC), broadband connections use modems.
Network navigation devices: Facilitate and control data flow (routers, switches).

Network Software

Operating system for P2P networking
Client/server network communications through a central server; specialized network operating system (NOS) software.

Connecting to the Internet

Broadband Internet connections are preferred, but cellular or dial-up access may also be necessary.
Common broadband technologies include cable, DSL, and fiber-optic.

Connecting to the Internet: Wireless Access

Mobile broadband uses 4G or 5G wireless access.
Wireless internet at home uses WiFi through a router.
Mobile hotspot provides internet access away from home.

Installing and Configuring Home Networks

List all devices.
Use latest standards for equipment.
Routers are specific to devices (iPhones, Windows PCs). Switches facilitate traffic.

Specialized Home Networking Devices

Network-attached storage (NAS) devices for data storage and access.
Home network servers for file storage and sharing.
Network-ready devices connect to the network.

Troubleshooting Wireless Network Problems

Maximum range of about 350 feet.
Walls, floors, metal objects interfere with signals.
Place access point where signal is weak.
Wireless range extenders repeat or amplify signals.

Managing and Securing Wireless Networks

Use encryption and security protocols.
Change Network Name (SSID).
Disable SSID broadcast.
Change default password.
Create a passphrase.
Implement media access control (MAC).
Limit signal range.
Update router firmware.
Disable remote access.
