Networking terms Flashcards
ARP
address resolution control protocal
frame
The data link layer prepares a packet for transport across the local media by encapsulating it with a header and a trailer to create a frame
dns
Most applications use DNS (Domain Name System) to determine the IP address when given a domain name
multicast
a form of transmission in which a message is delivered to a group of hosts
NETSTAT
the command netstat to list the protocols in use, the local address and port numbers, the foreign address and port numbers, and the connection state
broadcast
a form of transmission in which a message is delivered to all hosts on a network
LAN
Local Area Network (LAN) - A network infrastructure that provides access to users and end devices in a small geographical area, which is typically an enterprise, home, or small business network owned and managed by an individual or IT department
circuit switched
A circuit-switched network is one that establishes a dedicated circuit between the source and destination before the users may communicate
WAN
Wide Area Network (WAN) - A network infrastructure that provides access to other networks over a wide geographical area, which is typically owned and managed by a telecommunications service provider
default gateway
The default gateway address is the IP address of the router that the host will use to access remote networks, including the Internet
tcp
transmission control protocol
ping
a utility that sends a series of echo requests from one IP host to another IP host and that processes the echo reply messages to test connectivity between the devices
Router
A router is a networking device that forwards data packets between computer network
switch
A network switch is a small hardware device that joins multiple computers together within one local area network
client
Clients are computers with software installed that enable them to request and display the information obtained from the serveR
Qos
quality of service - a mechanism to manage the flow of traffic based on different requirements to ensure reliable delivery of each type of traffic
traceroute
a utility that generates details about the route traveled by data sent between two devices
DSL
Digital subscriber line - technology that provides the user with a high-bandwidth connection to the Internet over a telephone line
WLAN
Wireless LAN (WLAN) - Similar to a LAN but wirelessly interconnects users and end points in a small geographical area.
hub
A Hub connects multiple Ethernet devices together
DHCP
dynamic host control protocol - a service that is used in networks to automatically configure IP addresses on devices
VPN
Virtual private networks (VPN) – These are used to provide secure access to remote workers
UDP
user data protocol
packet switched
One way reliable networks provide redundancy is by implementing a packet-switched network. Packet switching splits traffic into packets that are routed over a shared network
unicast
a form of message delivery in which a message is delivered to a single destination
NAT
Network Address Translation - provides a way for multiple devices to share a single public IPv4 address
server
Servers are computers with software that enable them to provide information, like email or web pages, to other end devices on the network
