FUNDAMENTAL CHARACTERISTICSOF DATA COMMUNICATION. The effectiveness of a data communicationsystem depends on three characteristics. 1. Delivery: The system must deliver data tothe correct destination. 2.
Accuracy: The system must deliver dataaccurately. 3. Timeliness: The system must deliver datain a timely manner. COMPONENTS OFDATA COMMUNICATION. FIVE COMPONENT OF DATA COMMUNICATION.

It provideagreement between sender andreceiver devices. SYNTAXStructure or format of the data;for example, fist 8bits areflag, 2nd 8bits are destinationaddress, other 32 bits formassage and last 8bits are forsource address.
SEMANTICSthis refers to the meaning of eachsection of bits, how the particularpattern to be interpreted is and whataction to be taken. For example10101010, pattern as a flag (start ofdata stream). TIMINGwhen the data sending,how fastthey can send for example senderis send data at 100 mbpsspeed, receiver is receive data at10 mbps what will happen, datawill be lost!.
