Chaos engineering
Chaos engineering: A method of testing the resilience and robustness of systems by intentionally introducing failures or disruptions into a system in a controlled manner. It is used to identify and address potential weaknesses or vulnerabilities in a system and to ensure that it can withstand unexpected failures or events. Examples of chaos engineering include […]
Caesar cipher
Caesar cipher: A type of substitution cipher that is used to encode messages by shifting each letter in the original message by a fixed number of places in the alphabet. It is a simple and easily breakable cipher but is still sometimes used as a basic form of encryption for simple communication or as a […]
Central Processing Unit (CPU)
Central Processing Unit (CPU): The primary component of a computer that performs most of the processing inside a computer. Known as the “brain” of the computer, it executes instructions from programs, performing basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions. The CPU’s performance is a key determinant of the computer’s overall […]
Check Digit Verification (Self-Checking Digit)
Check Digit Verification (Self-Checking Digit): A form of error detection mechanism that ensures the integrity of data during transmission or entry. It involves using a formula to calculate a check digit from the other digits in a string and then comparing that check digit to the one included with the string. If the calculated check […]
Callback
Callback: In the context of secure communications, callback is a method of authenticating a user where a server initiates a new connection to the user’s registered contact information (e.g., phone number or IP address) after receiving a request. This ensures that the access request is indeed coming from a trusted source. This method, though not […]
