Network Hardware
A host that provides service for computers and other devices within an area
what is a server
A type of software identifies which portion of the IP address is the network address and which portion is the host address.
what is a subnet mask
this type of connection uses a modem connected to the phone line to connect to the internet.
what is dial up
this command displays IP configuration information for network adapters.
what is ipconfig
the term used to describe how devices are connected and how messages flow from device to device.
what is Topology
A LAN device that receives a signal on one port and forwards that signal only to the port where the destination device is connected.
what is a switch
A piece of software that identifies both the logical host and the logical network addresses.
what is an IP address
this type of connection provides broadband digital data transmission over existing telephone lines.
what is DSL
this command is used on Linux and macOS systems and displays the installed network interfaces and the current configuration settings for each interface, including the MAC address, IP address, broadcast address, and subnet address.
what is ifconfig
that uses a hub or switch to connect all network connections to a single physical location. Today, it is the most popular type of topology for a LAN.
what is a star
A device that provides voice communication over an IP network. The most common place to find this device is a phone.
what is VoIP
this server address identifies the server that is used to resolve hostnames to IP addresses.
what is a DNS server
this type of connection uses a cable TV connection to create a wide area connection to the internet.
what is cable
this command sends an ICMP echo request/reply packet to a remote host. A response from the remote host indicates that both hosts are correctly configured and a connection exists between them.
what is ping
this connects neighboring nodes until they form a circle. Signals travel in one direction around the circle; each device on the network acts as a repeater to send the signal to the next device.
what is a ring
a device that is optimized to provide a single service file sharing.
what is a NAS
IP hosts contact this server for IP addressing and other configuration information. This ensures error-free host configuration.
what is DHCP
this type of connection uses the cellular phone infrastructure for internet access.
what is celluar
this command looks up the IP address of the specified hostname. It also displays additional name resolution information, such as the DNS server used for the lookup request.
what is nslookup
this exists when there are multiple paths between any two nodes on a network. this topology is created using point-to-point connections. This increases the network's fault tolerance because alternate paths can be used when one path fails.
what is a mesh
A type of hardware device that regenerates a signal out to all connected ports without examining the frame or packet contents?
what is a Hub
this software identifies the router to which communications for remote networks are sent. The software's address is the IP address of the router interface on the same subnet as the local host.
what is a default gateway
this type of connection uses radio signals sent and received from a satellite. This is divided into two categories (GEOs) and (LEOs).
what is satellite networking
this command is similar to the ping utility because it tests connectivity between devices; however, this command also shows the path between the two devices. Responses from each hop on the route are measured three times to accurately report how long the packet takes to reach the specific host and then return.
what is tracert
this consists of a trunk cable with nodes either inserted directly into the trunk or tapped into the trunk using offshoot cables called drop cables.
what is a bus
