The full form of “CTC” can vary depending on the context, but in the context of employment and salaries, CTC typically stands for “Cost to Company.” It refers to the total amount a company spends on an employee in a year, including salary, benefits, and any other perks.
In other contexts, CTC could stand for different things, such as “Cyclic Triaxial Compression” in engineering or “Computer-to-Computer” in technology. If you have a specific context in mind, please let me know!
