Random process refers to a collection of all the random variables that are indexed by time. These processes signify the mathematical model of random signals. Random processes are most commonly used for modeling communication systems and are applied in engineering and other scientific applications. Random processes questions and random signals questions are asked in the previous GATE papers, ESE, PSU papers, NDA exams, etc. There are several resources available on the internet, such as Random processes notes for GATE ECE PDF to study Random processes for computer science. However, if you want to refer to a Random processes book or Random processes GATE notes, you can also get many good options on the internet.
