Networking

CSMA/CD determines how network devices respond when two devices use data. Ethernet uses CSMA/CD to monitor traffic. If no transmission is taking place, the device can transmit. If two devices attempt to transmit at the same time, this can cause a collision. After a certain time, the devices that collided can attempt to transmit again. If another collision occurs, the waiting time is increased.

A Token Ring is a local area network where all computers are connected in a ring or star topology and a token ring is used in order to prevent collision of data between two devices that want to send data at the same time. This protocol is the second used protocol on local area networks after Ethernet. The IEEE 802.5 Token Ring technology

It uses protocols such as TCP/IP. Browsers use TCP when they request a connection to websites on the internet. TCP/IP can also send emails, receive emails and transfer files.

AppleTalk is built into apple products. AppleTalk supports Ethernet. It will connect products if they are installed with AppleTalk hardware and software. Apple talk compatible with only Apple products.

UDP is a transport layer protocol that uses the IP protocol. It provides a datagram to an IP host. UDP is unreliable and provides no guarantees for delivery. Whereas TCP/IP checks if the file has been received successfully.

Infrared uses infrared waves to send files from one device to another. It can send media wirelessly but both devices have to be very close together to receive files.

3G is used calls, internet access, wireless, video calling and streaming. It can provide mobile data at a rate of 200kbit/s.

4G is a faster and more adapted version of 3G. It provides internet access as well as the normal voice and SMS services. 4G users can often get speeds beyond 100Mbps which can preview high definition
