Absolute data remanence(permanently deleting data) is a critical concept in the field of data security. It refers to the residual traces of data that remain on a storage device even after the data has been deleted. These traces can potentially be recovered and reconstructed, thereby exposing sensitive information to malicious actors. As a result, understanding…
Introduction to GPUs: A GPU, or Graphics Processing Unit, is a specialized computer chip that is designed to handle tasks related to visual data processing and rendering. The main function of a GPU is to generate images and video, but they are also used for other computationally intensive tasks such as scientific simulations and machine…
Wiretapping, also known as phone tapping or electronic surveillance, is the interception of electronic communication transmitted over phone lines, the internet, or other communication networks. It is a form of surveillance that is often used by law enforcement agencies and intelligence agencies to gather information and evidence for criminal investigations and national security purposes. Wiretapping…
Punch card Punch cards were a type of data storage and processing technology that was widely used in the early days of computing. They were first invented in the 17th century for use in looms, and were later adapted for use in computers. Punch cards were made of stiff cardboard or paper, and had rows…
What is Blockchain? Blockchain is a decentralized and distributed digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This allows for the secure and transparent transfer of data and assets without the…
Computer science’s application of quantum theory is known as quantum computing. Subatomic particles, such electrons or photons, are used in quantum computing. These particles can exist in more than one state (1 and 0) concurrently thanks to quantum bits, or qubits. Quantum computers use qubits, while normal computers store data as bits with either 0s…
Implementation of queue can be done using two stacks. Queue using stack can be done in two ways. By making the enqueue (insertion) operation costly.
