transport

which layer of the OSI model provides controls for error-free transmissoin?

datalink

what layer of the OSI model is first one responsible for error checking?

switch

network device working in the datalink layer responsible for connecting devices to a network

router

network device working in the networking layer responsible for routing packets and segmentation

hub

network device operating in the physical layer that connects devices to a network

repeater

network device working in the physical layer that comes with 2 ports that transform incoming signals into outgoing signals before the data reaches its destination.

bridge

network device that works in the datalink layer, responsible for routing packets by connecting networks. It’s similar to a road that connects to land masses separated by water.

modem

network device with features of other networking devices responsible for connecting small networks to the internet

firewall

network device operating in the transport layer responsible for allowing or rejecting traffic from the internet based on preset rules.

gateway

network device that operates in all layers of the OSI model, responsible for connecting networks

switch

what network device only sends data from the source port to the destination port?

interworking operating system (IOS)

the operating system of a router

IP address

the ID representing a device on a network

IPv4

what type of IP address is 192.168.4.1 an example?

4

how many octets in an IPv4?

private IP address

An IP address represents a device on a private network and connects to the internet via a dedicated network device.

localhost

IP addresss representing a device’s own network address

network address translation (NAT)

method that converts a private IP address to a public IP address that represents a device on the internet
