Study Notes

Network Terminology

Sneakernet: an informal term for transferring electronic information by physically moving media between computers, rather than transmitting over a network.

Data Networks

LAN (Local Area Network): a computer network that spans a small geographical area, typically within a building or campus.
WAN (Wide Area Network): a computer network that spans a large geographical area, often connecting multiple LANs.
Examples of data networks: internet, intranet, extranet.

Networking Devices

Repeater: a device that amplifies and retransmits a signal to extend the distance of a network.
Bridge: a device that connects two networks and filters traffic between them, dividing a collision domain but not a broadcast domain.
Switch: a fast, multi-port bridge that connects multiple networks and filters traffic between them.

Network Topology

A network topology is the arrangement of devices and connections in a network.
The diagram shows a network of moderate complexity, typical of a school or small business.

Network Protocols

A protocol is a formal description of rules and conventions that govern device communication on a network.
Organizations and committees governing protocols: IEEE, ANSI, TIA, EIA, ITU.

Storage-Area Networks (SANs)

SAN: a dedicated, high-performance network used to move data between servers and storage resources.
SAN technology allows high-speed server-to-storage, storage-to-storage, or server-to-server connectivity.

Network Attached Storage (NAS)

NAS devices: storage arrays or gateways supporting file-based storage protocols (NFS, CiFS), connected via IP network.
NAS provides shared file level access to storage resources, reducing management complexity and improving storage utilization rates.

NAS vs SAN

Primary difference: type of access protocol.
NAS protocols (NFS, CiFS) provide shared file level access, with file system management residing with the NAS device.
SAN protocols (iSCSI, fibre channel) provide block level access, with file system management residing with the server.

Virtual Private Network (VPN)

A VPN is a private network constructed within a public network infrastructure (e.g. internet).
VPNs allow remote access to a company network over the internet, building a secure tunnel between the telecommuter's PC and a VPN router.

Bandwidth

Bandwidth is limited by physical and technological constraints.
Importance of bandwidth: critical to network performance, limited, not free, and growing rapidly.
Pipe and Highway analogies illustrate bandwidth concepts.

Throughput

Throughput: measure of bits transferred across a medium over a given period.
Units of bandwidth: bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), gigabits per second (Gbps).
