When it enters into the atmosphere, light contributes to sky glow.

When a meteoroid enters the atmosphere, frictional, pressure, and chemical interactions with the atmospheric gasses cause the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting / falling star.

When an unlabeled packet enters the ingress router and needs to be passed on to an MPLS tunnel, the router first determines the forwarding equivalence class ( FEC ) the packet should be in, and then inserts one or more labels in the packet's newly created MPLS header.

When this phase comes to an end, the star enters the PPN phase.

When a prion enters a healthy organism, it induces existing, properly folded proteins to convert into the disease-associated, prion form ; the prion acts as a template to guide the misfolding of more proteins into prion form.

When the Vikings returned in force in 892 they found a kingdom defended by a standing, mobile field army and a network of garrisoned fortresses that commanded its navigable rivers and Roman roads.

When powered on, an AppleTalk machine broadcasts an AARP probe packet asking for a network address, intending to hear back from controllers such as routers.

When sent over an IP network, all records use the common format specified in RFC 1035:

When it receives a request from a client, the DHCP server determines the network to which the DHCP client is connected, and then allocates an IP address or prefix that is appropriate for the client, and sends configuration information appropriate for that client.

When a DHCP-configured client ( a computer or any other network-aware device ) connects to a network, the DHCP client sends a broadcast query requesting necessary information to a DHCP server.

When the injunction came into force versions later than 5. 5. 10 left the network or were disabled as users started them.

When the number of nodes along each dimension of a toroidal network is 2, the resulting network is called

When first connected to a network, a host sends a link-local router solicitation multicast request for its configuration parameters ; if configured suitably, routers respond to such a request with a router advertisement packet that contains network-layer configuration parameters.

When privacy extensions are enabled, the operating system generates ephemeral IP addresses by concatenating a randomly generated host identifier with the assigned network prefix.

When the advertising method is shown to be a complete fraud, the resulting public reaction against the network leads to the chairman being removed, and Grossberg manages to assume the chairmanship.

When network effect is present, the value of a product or service is dependent on the number of others using it.

When negative feedback is used, the circuit's overall gain and response becomes determined mostly by the feedback network rather than by the op-amp itself.

; Out-of-order delivery: When a collection of related packets is routed through a network, different packets may take different routes, each resulting in a different delay.

When the expense of mechanisms to provide QoS is justified, network customers and providers can enter into a contractual agreement termed a service level agreement ( SLA ) which specifies guarantees for the ability of a network / protocol to give guaranteed performance / throughput / latency bounds based on mutually agreed measures, usually by prioritizing traffic.

When each router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the network addresses in the routing table.

When applying link-state algorithms, each node uses as its fundamental data a map of the network in the form of a graph.
