MAN
MAN (Metropolitan Area Network) is a network that spans a city or large campus, providing high-speed data connections and typically linking multiple LANs within a geographical area, such as a city or a large university.
Hub
Hub is a multiport repeater
Bridge
Bridge is a LAN device used to connect LAN segments
Forwarding Tables
Forwarding Tables are data structures used by network devices like routers and switches to determine the next hop or destination for incoming data packets based on the packet’s destination address, facilitating efficient packet routing or switching.
Spanning Tree Algorithm (STA) vs STP
(Spanning Tree Protocol)
Spanning Tree Algorithm (STA) is the algorithm used by network devices (such as switches) to calculate the best loop-free path for data across a network, forming the foundation for Spanning Tree Protocol (STP).
STP (Spanning Tree Protocol) is a protocol based on STA, used in Ethernet networks to prevent network loops by disabling redundant paths and allowing only one active path between switches, ensuring a loop-free topology.
Mulitlayer switch
Network device that combines the functionality of both a Layer 2 switch (data link layer) and a Layer 3 router (network layer), enabling it to perform switching within a local network and routing between different network segments or VLANs.
VLAN
Enable administrators to separate and group computers logically
based on resource requirements, security, or business needs
*instead of the standard physical location of the systems
packet tagging
Packet Tagging is the process of adding an identifier or tag to data packets, often used in VLANs (Virtual Local Area Networks) to distinguish between different traffic types, enabling switches and routers to correctly forward packets based on their VLAN membership.
Gateway
A Gateway is a network device that acts as an entry/exit point between different networks, often serving as a translator between different communication protocols or network architectures (e.g., from a local network to the internet).
proxy server
a server (a computer system or an application) that acts as
an intermediary for requests from clients seeking resources
from other servers.
Private Branch Exchange
A Private Branch Exchange (PBX) is a private telephone
switch that is located on a company’s property.
