This article throws light upon the top five schemes of encoding data bytes. The schemes are: 1. Non-return to Zero (NRZ) 2. Non-return to Zero Invert on Ones (NRZI) 3. Bipolar-AMI 4. Manchester Code 5. Differential Manchester Code. Scheme # 1. Non-Return to Zero (NRZ): A common way—probably the most common way—to transmit digital signals is to use two different [...]
After reading this article you will learn about: 1. Rules of Data Transmission 2. Analog and Digital Data Transmission 3. Transmission Impairments 4. Modulation 5. Modems 6. Error Detection 7. Error Correction. Rules of Data Transmission: The design decisions that concern the rules for data transfer require that one specifies whether data will travel in only one direction or both [...]
This article throws light upon the top six methods of data transmission. The methods are: 1. Twisted Pair 2. Shielded Twisted Pair 3. Baseband Coaxial Cable 4. Broadband Coaxial Cable 5. Fibre Optics 6. IEEE Standards. Method # 1. Twisted Pair: As must be obvious from the example, transferring data by copying it onto magnetic tape or floppy disk or [...]
