A
Absolute Value: In mathematics, the absolute value of a number is its distance from zero on the number line. It's always a non-negative value. For example, the absolute value of 5 is 5, and the absolute value of -5 is also 5. It's often denoted by two vertical bars, like |x|.
Algorithm: An algorithm is a step-by-step procedure or a set of rules designed to perform a specific task or solve a particular problem. Think of it like a recipe: it gives you exact instructions to achieve a desired outcome. Algorithms are fundamental to computer science and are used in everything from sorting data to making complex calculations.
API (Application Programming Interface): An API is a set of definitions, protocols, and tools for building application software. In simpler terms, it's a way for different software applications to communicate with each other. It acts as an intermediary, allowing one program to request services or data from another without needing to know the intricate details of how that other program works.
Argument: In programming, an argument is a value passed to a function or method when it is called. It's the actual data that a function operates on. For instance, if you have a function add(a, b), then a and b are parameters, and when you call add(5, 3), the values 5 and 3 are the arguments.
Asynchronous: In computing, an asynchronous operation is one that does not occur at the same time as the main program flow. This means that the program can continue to execute other tasks while the asynchronous operation is running in the background, without waiting for it to complete. This is crucial for maintaining responsiveness in applications, especially when dealing with potentially long-running tasks like network requests or file I/O.
B
Bandwidth: Bandwidth refers to the maximum rate of data transfer across a given path. It's often measured in bits per second (bps). Think of it like the width of a pipe: a wider pipe can carry more water at once. In networking, higher bandwidth means faster data transfer speeds.
Binary: Binary is a base-2 number system that uses only two digits: 0 and 1. This is the fundamental language of computers, as electronic circuits can easily represent these two states (on/off, high/low voltage). Every piece of data a computer processes is ultimately represented in binary.
Bit: A bit (short for binary digit) is the smallest unit of data in computing. It can have only one of two values, typically represented as 0 or 1. A group of bits can represent more complex information, such as numbers, letters, or instructions.
Boolean: A boolean is a data type that can have only one of two possible values: true or false. Boolean logic is the foundation of computer programming and decision-making processes. Conditions in code, like if x > 5, evaluate to a boolean value.
Bug: A bug is an error, flaw, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. Debugging is the process of finding and fixing these bugs.
C
Cache: A cache is a temporary storage area that stores frequently accessed data to speed up future requests. It's like having a small, easily accessible notepad for information you use all the time, rather than having to retrieve it from a larger, slower filing cabinet every time. Web browsers and processors often use caches.
Cloud Computing: Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”). It offers faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs and run your infrastructure more efficiently.
Compiler: A compiler is a special program that translates source code written in a high-level programming language (like Python or Java) into a lower-level language (like machine code) that a computer's processor can understand and execute. This translation process happens all at once before the program is run.
Cookie: A cookie is a small piece of data sent from a website and stored on the user's computer by the user's web browser while the user is browsing. Cookies are commonly used to remember information about the user, such as login details or preferences, for future visits.
CPU (Central Processing Unit): The CPU is the primary component of a computer that performs most of the processing inside a computer. It's often referred to as the
