An algorithm is a step-by-step procedure or formula for solving a problem. It’s a finite sequence of well-defined instructions, typically used to solve a specific class of problems or to perform a computation. For example, an algorithm could be used to sort a list of numbers or to search for a specific item in a database.
API (Application Programming Interface)
An API is a set of rules and specifications that software programs can follow to communicate with each other. It allows different systems to exchange data and functionality without needing to know the underlying implementation details. For example, an API can allow a web application to access data from a social media platform.
Binary Code
Binary code is a system of representing text or computer processor instructions by using the binary number system’s two symbols: 0 and 1. It’s the fundamental language that computers understand. For example, the letter ‘A’ might be represented as 01000001 in binary code.
Bug
A bug is an error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. Bugs can range from minor inconveniences to major system failures. For example, a bug might cause a program to crash or to display incorrect information.
Compiler
A compiler is a computer program that translates code written in a high-level programming language into a lower-level language (e.g., machine code) that can be executed by a computer. Compilers are essential tools for software development. For example, a compiler can translate Java code into bytecode that can be run on a Java Virtual Machine.
Data Structure
A data structure is a particular way of organizing and storing data in a computer so that it can be used efficiently. Different kinds of data structures excel at different tasks. For example, an array is a simple data structure that stores elements in a contiguous block of memory, while a linked list is a more flexible data structure that can grow and shrink dynamically.
Debugging
Debugging is the process of finding and fixing bugs in computer programs or systems. It involves identifying the source of the bug, understanding why it’s occurring, and implementing a fix that resolves the issue without introducing new problems. For example, a Computer Teacher might guide students through debugging a program that’s producing incorrect output.
Firewall
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, such as the Internet. For example, a firewall can block unauthorized access to a school’s computer network.
HTML (Hypertext Markup Language)
HTML is the standard markup language for creating web pages. It provides the structure and content of a web page, using elements such as headings, paragraphs, images, and links. For example, a Computer Teacher might teach students how to write HTML code to create their own websites.
IDE (Integrated Development Environment)
An IDE is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools, and a debugger. For example, Visual Studio Code is a popular IDE used by many Computer Teachers and students.
Iteration
Iteration is a process wherein a set of instructions or structures are repeated in a sequence a specified number of times or until a condition is met. In programming, this often involves loops. For example, iterating through an array to perform a calculation on each element.
Machine Learning
Machine learning is a type of artificial intelligence (AI) that allows computer systems to learn from data without being explicitly programmed. It involves training algorithms to identify patterns and make predictions based on data. For example, a machine learning algorithm can be trained to recognize images or to predict customer behavior.
Operating System
An operating system (OS) is the software that manages computer hardware and software resources and provides common services for computer programs. It acts as an interface between the hardware and the applications that run on the computer. For example, Windows, macOS, and Linux are popular operating systems.
Programming Language
A programming language is a formal language used to instruct a computer to perform specific tasks. It consists of a set of syntax rules and semantics that define how the code should be interpreted. For example, Python, Java, and C++ are popular programming languages.
Recursion
Recursion is a programming technique where a function calls itself in order to solve a problem. It involves breaking down a problem into smaller, self-similar subproblems until a base case is reached, which can be solved directly. For example, recursion can be used to calculate the factorial of a number.
The Mistake That Quietly Kills Candidates
The biggest mistake is using vague language and generic definitions. Hiring managers and stakeholders need to see that you understand the practical application of these terms. If you just recite textbook definitions, you’ll come across as inexperienced. For example, don’t just say you know what an API is; explain how you’ve used one to integrate different systems.
Use this when you want to impress someone in an interview:
“An API, or Application Programming Interface, is a set of protocols that allows different software systems to communicate. For example, in my previous role, I used the Google Maps API to integrate mapping functionality into our school’s website, improving navigation for parents and visitors.”
