List out the limitation of parallel communication. Explain the different operation modes of 8255A PPI. [5]
--- Parallel communication transmits multiple bits simultaneously over multiple lines, but it has the following limitations: 1. Cost: Requires more wires/lines (one for each bit), making it more expensive than serial communication. 2. Distance Limitation: Suitable only for short distances (typica...
