What mistakes should MCA students avoid while learning computer networks?

Computer networks explain how devices and systems communicate. Topics such as TCP/IP, routing, switching, DNS and network layers give MCA students a foundation for software and infrastructure roles. If your target role involves computer networks, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the computer networks aspect of MCA study. For this specific question about computer networks, the practical takeaway is to relate the concept to your own MCA learning goal.
