Bandwidth
Bandwidth is the capacity of a connection to carry data in a given time, usually described in megabits per second.

A focused reference
Networking concepts.
Throughput
Throughput is the amount of data successfully delivered over time.
Explore →Latency
Latency is the time information takes to travel through a network or complete a network exchange.
Explore →Jitter
Jitter is variation in the timing of arriving network data.
Explore →Packet loss
Packet loss occurs when transmitted network packets do not reach their intended destination.
Explore →TCP
Transmission Control Protocol provides a reliable, ordered stream of bytes between network endpoints.
Explore →UDP
User Datagram Protocol sends individual datagrams without supplying TCP's ordered, reliable byte-stream service.
Explore →QUIC
QUIC is a secure transport protocol built over UDP, with reliability and stream-management behavior above that datagram foundation.
Explore →DNS
The Domain Name System translates names into information such as the IP addresses used to reach a service.
Explore →DNS cache
A DNS cache stores recent name-resolution answers so a client does not need to repeat the full lookup process for every request.
Explore →DNS TTL
DNS time to live, usually shortened to TTL, is the period for which a DNS answer may be retained in a cache.
Explore →IPv4
IPv4 is a network-layer addressing protocol using 32-bit addresses.
Explore →IPv6
IPv6 is a network-layer protocol using 128-bit addresses.
Explore →NAT
Network address translation rewrites address information as traffic crosses a router.
Explore →Double NAT
Double NAT occurs when a connection crosses two routers that each perform address translation.
Explore →CGNAT
Carrier-grade NAT is address translation operated within an internet provider's network, allowing several subscribers to share public IPv4 addressing resources.
Explore →DHCP
Dynamic Host Configuration Protocol supplies network configuration automatically.
Explore →Default gateway
The default gateway is the next-hop router a device uses for destinations outside its directly connected network when no more specific route applies.
Explore →Ethernet
Ethernet is a wired local-network technology connecting devices through suitable cables and ports.
Explore →Wi-Fi airtime
Wi-Fi airtime is the time a device occupies a shared wireless channel to send or receive information.
Explore →2.4 GHz Wi-Fi
The 2.4 GHz Wi-Fi band is a range of radio spectrum used by many wireless devices.
Explore →5 GHz Wi-Fi
The 5 GHz Wi-Fi band offers more channel choices and often higher practical throughput than crowded 2.4 GHz connections near a suitable router.
Explore →6 GHz Wi-Fi
The 6 GHz band provides additional spectrum for compatible Wi-Fi equipment under the applicable regional rules.
Explore →Wireless signal strength
Wireless signal strength describes the received radio level from an access point or client.
Explore →Wi-Fi channel width
Wi-Fi channel width determines how much radio spectrum a connection occupies around its operating channel.
Explore →Mesh backhaul
Mesh backhaul is the connection carrying traffic between a mesh satellite and the main router or another upstream node.
Explore →Wi-Fi roaming
Wi-Fi roaming moves a client between access points serving a network.
Explore →Network congestion
Network congestion occurs when demand exceeds the capacity of a resource along a delivery path.
Explore →Bufferbloat
Bufferbloat is excessive network delay caused by packets waiting in a persistently full queue.
Explore →Upload saturation
Upload saturation occurs when outgoing traffic uses all available upstream capacity.
Explore →VPN tunnel
A VPN tunnel carries selected network traffic between a device or router and a remote endpoint, commonly adding encryption around that traffic.
Explore →Proxy server
A proxy server receives requests on behalf of a client and forwards them to another server.
Explore →Captive portal
A captive portal is a network access process that requires a sign-in, payment, room code or acceptance of terms before normal internet use is available.
Explore →Firewall
A firewall applies a policy to network traffic, allowing, rejecting or silently dropping connections according to configured rules.
Explore →Port number
A port number identifies a logical endpoint used by a transport protocol on a host.
Explore →MTU
Maximum transmission unit, or MTU, is the largest network-layer packet that a particular link can carry without fragmentation.
Explore →MAC address
A MAC address identifies a network interface at the link layer, such as a Wi-Fi or Ethernet interface.
