Artificial intelligence (AI) is a rapidly growing field of computer science that involves the development of computer systems and algorithms that can perform tasks that normally require human intelligence. This includes tasks such as understanding language, recognizing images, making decisions, and learning from data. AI has the potential to transform many aspects of our lives,…
A hard disk drive (HDD) is a type of storage device that is commonly used in computers. It is called a “hard” drive because it uses a physical spinning disk to store data, as opposed to solid-state drives (SSDs) which use memory chips. There are several different types of HDD drives that are used for…
An API (Application Programming Interface) is a set of rules and protocols that allow software components to communicate with each other. It defines the types of requests that can be made, the format of the data that should be used, and the conventions to follow. Application Programming Interface is used to enable communication and data…
Central Processing Unit (CPU) is the primary component of any computer system. It carries out instructions from a computer program and processes data. It is a single chip that acts as a complete computational engine. The first microprocessor, the Intel 4004, was introduced in 1971. While it was not very powerful and could only perform…
Data science is the study of how to extract knowledge and insights from large and complex datasets. It is an interdisciplinary field that combines principles and skills from computing, statistics, and expertise to develop methods and tools for analyzing and interpreting data. One of the key tasks in data science is to develop algorithms and…
The history of computers is a long and fascinating one, with the concept of a computer dating back centuries. However, the first recognizable modern computer was the Electronic Numerical Integrator And Computer (ENIAC), which was developed in the United States in 1945 (during World War II). The ENIAC was a massive machine, measuring over 80…
A programming language is a formal language that is used to write instructions that can be executed by a computer. These instructions, known as code, are written in a specific syntax that follows certain rules and conventions. This allows computers to understand and execute the instructions in a consistent and predictable manner. There are many…
The scientific method is a systematic process for conducting scientific research. It involves making observations, formulating hypotheses, testing hypotheses through experiments, and analyzing the results. The goal of the scientific method is to collect unbiased, reliable, and reproducible data that can be used to develop theories and explanations of problems. The scientific method is an…
A virtual machine (VM) is a virtual environment that functions as a virtual computer system with its own instance of an operating system (like Linux or Windows) sitting on top of a piece of software called a Hypervisor that runs on the actual physical computer hardware (CPU, Memory, Disk, Network, etc.). One or more virtual…
Nmap is an open-source networking utility (network scanner) used to discover IP addresses (hosts) and open ports on the network by sending packets and analyzing the responses. Nmap started as a Linux utility and was ported to other operating systems including Windows and macOS. Network engineers use Nmap for port scanning, ping sweeps, OS detection,…
