Analog modulation is the simplest form of the modulation. In analog modulation techniques, the modulation is applied continuously in response to the analog information
Normal communication signals loose strength as they travel to the large distances. Hence, we often transmit the signals through electromagnetic waves and we use
Ethernet is a commonly used protocol for LAN. IEEE 802.3 Ethernet uses 1 persistent CSMA/CD access method.
What is Ethernet?
For avoiding collision and to increase efficiency in sensing the channel, Carrier Sense Multiple Access (CSMA) is used. Many versions of CSMA are
For a large number of users the ALOHA protocol is considered. There are two versions of ALOHA that is Pure ALOHA and Slotted ALOHA.
Cyclic Redundancy Check
A cyclic redundancy check (CRC) or polynomial code checksum is a non-secure hash function designed to detect accidental
