- Protocols
- A set of rules that cover
data communications
- Transmission Control Protocol/Internet
Protocol has become the de facto standard
for data transmission over the internet
- Hosts are computer systems that are accessed
remotely and hold data such as web servers
- TCP is concerned with the connections
of hosts, not the nature of data
- Packets are collections of data forming part of a message
(constructed according to rules laid down by the protocol)
- Contains standard fields like: protocol, checksum,
total length, address, time to live, packet number, data
- IP is concerned with
construction of packets
- Packet switching is when packets from a particular message take different routes according to availability and traffic conditions (forwarded from one router to the next) and assembled at the receiving end
- Improves reliability if one route is down or congested, another can be found
- Adressing
- IP
- MAC
