Network Protocols
CSMA/CD is Carrier Sense Multiple Access/Collision Detection which is a method for managing data traffic on a LAN.
Token is a signal that passes round a network, it can be thought of as a carrier for packets of data. For data to travel it has to be attached to a Token
Ethernet is a general-purpose LAN which provides a physical connection between computers. Different types of computers can use the same Ethernet network at the same time.
TCP/IP is a general-purpose protocol allowing any networked computers to communicate with each other whatever their equipment.
Wi-Fi is a way of connecting computers to a network by wireless. Each computer has a Wi-Fi wireless interface that connects to a Wireless Access Point.
Bluetooth is a short range wireless communication standard. It allows Bluetooth equipped devices to communicate with other Bluetooth devices in a P2P relationship.
VoIP is a method of using the internet to make ordinary voice telephone calls. Digitised speech is just data sent over the internet as with any other data.
RFID is Radio-Frequency Identification which is where a small tag that can respond to a sensor operating at a short distance.
A Network Protocol is an agreed set of rules for the sending and receiving of data on a network to prevent data collisions.
-
1 Physical Layer is the level where the physical layer transmits and receives streams of bits and it specifies the voltage level and timings.

The OSI model is a set of protocols allowing computers of different origins to be linked together. OSI stands for Open Systems Interconnection Model and was developed by the International Standards Organisation. The OSI model is represented by seven layers which are from 7 to 1 Application, Presentation, Session, Transport, Network, Data Link and Physical.
Packet Switching is a method of sending data over a Wide Area Network. Packet Switching Networks are available for general use in most Countries. A packet is a group of bits made up of control signals, error control bits, coded information and the destination address of the data.
Other Communication protocols would be TCP/IP - Transmission Control Protocol/Internet Protocol, HTTP - Hyper Text Transfer Protocol, FTP - File Transfer Protocol, WAP - Wireless Access Protocol and VoIP - Voice over Internet Protocol
These Protocols define the Speed of Network, how to establish connection, format of data transmitted, how data errors will be detected, how errors will be corrected, methods of data compression and how the connection is terminated.
A communication protocol is a set of rules or procedures that enable devices on computer networks using different technologies to communicate.
Common Protocols are: TCP/IP - Transmission Control Protocol/Internet Protocol, HTTP - Hyper Text Transfer Protocol, FTP - File Transfer Protocol, WAP - Wireless Access Protocol and VoIP - Voice Over Internet Protocol
