Network classification are broadly based on these two basic approaches transmission technologies.
Classification based on Transmission Technology
Computer network can be broadly categorized into two types based on transmission technologies.
Point to point Network
In point to point network data of messages from one host is transmitted over to other host ( which are connected ) either director indirect. They are not intended to other. In direct link hosts are directly connected via a physical communication medium during data transfer. In indirect link the data is transferred over intermediate IMPs unit it reaches to destination host. Here the data from incoming line arrive at the intermediate IMPs( internet messaging program) which store it and waits for free l link. If it find free link the data is sent over it otherwise it sends over next intermediate IMPs. This process is repeated until the data is received by the destination host. A communication systems supporting point to point network is defined as point to point store and forward or packet switch subnet.
