Computer System : A computer is an electronic device which processes data based upon the instructions provided and generate the desired output.
IPO Cycle : The basic principle on which the computer works.
Computing Process: Input -> Process -> Output
The characteristics of computer are Speed, Accuracy, Automation, Endurance, Versatility, Storage, Reduction of processing cost, and Intelligence quotient.
Hacking is gaining unauthorized access to data in a system or computer with the intention of harming the system or the owner.
Cracking is somewhat similar to hacking, but difference is it is authorized access to check the protection of system by owner’s permission to protect the system from hackers.
A sequence of characters that one must input to gain access to a file, application, or computer system, also called passkey.
The process by which raw message information (plain text) is mapped or encrypted to a scrambled form (cipher text) before transmission or storage, then mapped back to its original form again (decrypted) when an authorized party wishes to read the plain text.
Computer System Engineering, also called computer engineering, is a discipline that integrates several fields of electrical engineering and computer science required to develop computer systems.
