A simple overview of network.
There is three ways to encrypt the data
- public key
- private key
- message digest (md5,sha)- normally we use checksum for authentication
-
IPV4
To distribute ip address in 32-bit addressing mechanism
-
IPV6
To distribute ip address in 128-bit addressing mechanism
TCP/IP is reliable protocol to transmit the data.
-
Keep-alive Timer
The validity of a connection.
-
Timed-Wait
Each host waits for a Timed-wait time to terminate the connection completely
When large amount of data sent to server which is not capable of handling it, then congestion occurs. TCP control the congestion by means of Window size mechanism.
