Flashcards in Networking and Internet Deck (36)
A standard set of rules that allows devices to communicate successfully. E.g. TCP
Specify data formats. eg linking computer to a printer
Guidelines to ensure that manufacturers of network equipment create product that are compatible with other manufacturers’ products. E.g. RJ45 connector
A group of protocols which allows all devices on a network (and internet) to communicate irrespectively of the equipment used.
Hyper text Transfer protocol:
Transferring (request and view)multimedia web
pages over the internet - Application Layer
File transfer protocol:
Copying a file from one location to another over the
internet - Application Layer
Simple mail Transfer protocol:
Mail applications typically use SMTP only for sending
email messages - Application layer
Internet Message Access protocol:
Transferring emails between computer systems via
the internet - Application layer
Dynamic Host Configuration Protocol:
a client/server protocol that automatically provides
an Internet Protocol (IP) host with its IP address
and default gateway - Application layer
User Datagram protocol:
Sending datagrams across a network with very
few error recovery services.- Transport layer
Transmission Control protocol:
Error control protocol defined for high-speed
communications within a network. - Transport layer
The exchange of signals between devices to establish their readiness to communicate
Global network of interconnected networks that use IP addresses and TCP/IP
A private network within an organization for employees. It uses internet technology, e.g. browsers & hyperlinks to allow communication.
A website that allows external stakeholders to access information usually by the use of usernames and passwords
World Wide Web
A collection of documents and other resources identified by URLs, interlinked by hypertext links, and accessed via the Internet
A set of links that connect geographically remote computers and local area networks
Group of devices, computers, printers, scanners under the control of one organization in a small geographic area
Device that connects networks that use different protocols
A software process that provides a service requested by a client
A software process that requests and uses the services provided by a server
A media access control address also called physical address, is a unique identifier assigned to network interfaces for communications on the physical network segment.
IP (v4) address
A unique address that identifies a device on a network. 32 bits e.g. 192.168.168.5
•Version - IPv4 / 6
•Total length - typically 64 bytes and 1500 bytes
•Identification - unique packet sequence number
•TTL - (Time to Live) decremented by 1 by each router until 0 when it is dropped.
•Protocol - The protocol of the transport layer
•Header checksum - Calculated at each hop to make sure that the header was not corrupted.
•Source IP address
•Destination IP address
Networking device that connects devices together on a (in one network) network using the MAC address, by using packet switching to receive, process and forward
data to the destination device.
device that connects networks that use the same protocol. It forwards packets by using the IP address.
Holds addresses of other devices in network so data sent to correct destination
A set of working practices that allow all internet users to communicate with each other whatever their equipment
Governs how two applications work with each other
Establishes the connection between applications (end
points) and governs aspects of end-to end communication between two end hosts. Splits message
up in packets, adds error checking details and port
Governs the transmission of packets across the internet –
typically by sending them through several routers along
the route. IP address of sender and receiver are added
to the packet.
