Difference between Concurrency and Parallelism in Go
Concurrency is when a program can handle multiple tasks at once while parallelism is when a program can execute multiple tasks at once using multiple processors. In other words, concurrency...
Types of Sampling
Any plan that relies on random selection is called a probability sampling plan (or technique). The following three probability sampling plans are among the most commonly used. Simple random sampling...
Components of AI
AI is a vast field for research and it has got applications in almost all possible domain. By keeping this in mind, research in AI has focussed mainly on the...
Error recovery techniques used by compiler
The error recovery techniques used by the compiler are as follows: Panic Mode Recovery This is the simplest method to implement and can be used by most parsing methods. On...
Confusion and Diffusion
The terms confusion and diffusion were introduced by Claude Shannon to capture the two basic building blocks for any cryptographic system. Shannon's concern was to thwart cryptanalysis based...
Diffie-Hellman Key Exchange Algorithm
The Diffie-Hellman algorithm is widely known as key exchange algorithm or key agreement algorithm developed by Whitfield Diffie and Martin Hellman in 1976. Diffie-Hellman is used to generate same (symmetric)...
Define the goals of security and specify mechanisms to achieve each goal.
Information security consists of methods used to protect data or information being transmitted for preserving the integrity, confidentiality, and availability of the information. Confidentiality Confidentiality is...
State the condition for stability of LTI system and determine for the given discrete time system, h(n) = (0.3)^nu(n) + 5δ(n), is stable of not.
Condition for the stability of LTI system: LTI system is stable if its impulse response is absolutely summable i.e., finite. ∑k=−∞∞|h(k)|<∞ h(n) = (0.3)nu(n) + 5δ(n) ∴∑k=−∞∞ [ (0.3)nu(n) +...
Spark Word Count program in Python
Here is the word count program in Python using Spark (pyspark) and Hadoop (hdfs). In this tutorial, you will get to know how to process the data in spark using...
What are block ciphers? Explain with examples the ECB and CBC modes of block ciphers.
A block cipher encrypts a block of plaintext as a whole and produces a ciphertext block of equal length. A block cipher takes a fixed-length block of text of length...
Difference between IIR and FIR systems.
IIR FIR Impulse response is infinite. Impulse response is finite. May or may not be stable. Always stable. Have sharp cut-off hence faster. Comparativelyy slow. IIR is recursive. FIR is...
