Study Notes

Network Basics

A network consists of technologies that link computers, enabling communication and collaboration.
Data can be accessed simultaneously by multiple users with shared files stored on servers.

Uses of a Network

Files and software can be shared, with access levels set as needed.
Networked peripheral devices, like printers or faxes, reduce costs and are managed through print servers.
Personal communication tools include email, teleconferencing, videoconferencing, and VoIP (Voice over IP).

Data Management

File servers hold documents shared across various computers.
Networks facilitate simpler data backup through consolidated server backups.

Common Network Types

Local Area Network (LAN): Typically confined to an office, connecting computers, printers, and servers.
Wide Area Network (WAN): A larger network connecting multiple LANs, often using public or leased lines; the Internet is the largest WAN.
Campus Area Network (CAN): A LAN that spans a large geographic area, shared by various departments within an organization.
Metropolitan Area Network (MAN): Connects multiple organizations within a region, sharing resources.
Home Area Network (HAN): Connects devices in a home environment, like computers and entertainment systems.
Personal Area Network (PAN): A very small network, usually under 2 meters, including personal devices like smartphones and MP3 players.

Network Structures

Server-based Network: Centralized control by servers determining node access.
Client/Server Network: Nodes act as clients, sharing data while the server regulates access.
Peer-to-Peer Networks (P2PN): Equal nodes that control their resources and share directly with one another, ignoring server oversight.

Network Topologies

Topology defines the layout of the network which affects performance and size.
Packets are data pieces transmitted across the network, containing headers (addresses) and payload (data).
Bus Topology: All nodes connect to a single wire; easy to set up but slow and prone to crashes.
Star Topology: Nodes connect to a central hub; most common but vulnerable if the hub fails.
Ring Topology: Nodes form a circle; token-based data transmission prevents collisions but is slower.
Mesh Topology: All nodes interconnect; highly reliable but complex to set up.

Network Media

Links between nodes can vary in terms of speed, security, and size.
Wired Media:
- Twisted-Pair Cabling: Common in LANs; speeds from 1 Mbps to 1,000 Mbps.
- Coaxial Cable: Used for earlier networks; speeds up to 10 Mbps, largely obsolete.
- Fiber-Optic Cable: High-speed data through light; secure and immune to interference, reaching speeds up to 100 Gbps.
Wireless Media: Data transmitted via radio or microwave signals; easy to set up but harder to secure.

Network Hardware

Network Interface Cards (NIC): Enable node connectivity via a unique MAC address.
Hubs: Centralizing nodes in star topology; less efficient and secure.
Switches: Superior to hubs; single transmissions, enhancing speed and security.
Bridges: Connect multiple LANs and segment traffic based on MAC addresses.
Routers: Connect LANs and segment networks based on IP addresses; essential for Internet connectivity.
Gateways: Interface between different network types, converting signals as needed.

Network Cabling

Bandwidth and cable length directly affect network performance.
Ethernet: Popular technology, max bandwidth of 10 Mbps over distances of 100-500 meters.
Fast Ethernet: Up to 100 Mbps; requires Cat5 or better cabling.
Gigabit Ethernet: Achieves 1 to 10 Gbps for high-throughput applications.
Token Ring: Uses twisted-pair cabling with speeds of 10-25 Mbps, common in certain industries.

Network Protocols

Protocols are communication rules that determine how data is handled on networks.
TCP/IP: The most widely-used protocol; comprises Transmission Control Protocol and Internet Protocol for identifying machines via IP addresses.
IPX/SPX: An older protocol tied to Novell Netware, largely replaced by TCP/IP.
NetBEUI: Used in Windows networks for name recognition; works alongside TCP/IP.
Token Ring Protocol: Nodes pass a token to communicate, ensuring orderly data transmission.
