RS 232

RS232 transmitter demo This applet demonstrates the transmitter part of a serial communications interface. The circuit converts incoming 8-bit ASCII (or rather ISO-8859-1) data into a serial RS-232 protocol data stream at 1200 baud

Shannon's Experiment to Calculate the Entropy of English Claude Shannon, the inventor of information theory, devised an experiment aimed at determining the entropy of an English letter (the amount of information in bits that we obtain on the average when we learn one letter of English)

SNMP Protocol Overview Network management tools, simple network management protocol (SNMP) was born for TCP/IP

TCP demo-applet The TCP demo-applet simulates a single-directional unicast data transmission in a number of problematic scenarios

TCPIP reliable connection, ensured delivery of packets between two nodes in a network, allows user to damage or destroy packets
