This interview question aims to check your knowledge of common programming terminology and concepts. Answer this question carefully to demonstrate your understanding of basic industry terminology.
What is a Programmer?
A programmer is a professional who builds, tests and troubleshoots the coding languages within software applications. This computer science and engineering career typically requires a bachelor’s degree or coding boot camp.
Programmers take software designs created by developers and translate them into code that instructs computers what to do. They also create and install updates for existing programs. They also analyze user feedback and make suggestions for coding improvements.
What is a Programming Language?
Programming languages are used to create computer programs. They are generally text-based and formal languages, but may also be graphical.
Procedural programming languages describe a system of state changes, while functional programming languages treat computation like math functions, which avoids state and mutable data. Python is an interpreted language that runs code line by line, and Java is a compiled language often used for website, application and game development.

What is a Variable?
Variables are “buckets” where information can be maintained. They are typically given a name and a data type, which determines and limits the form of the information stored in them.
Quantitative variables contain numeric data, which means that the numbers can be added, subtracted, divided and multiplied. Categorical variables contain data that can be classified into mutually exclusive or exhaustive categories.
What is a String?
A string is a sequence of characters that can include letters, symbols, and numbers. Most programming languages treat strings as a data type and store them in length controlled arrays.
A string can be used to communicate information from the program to the user, but it is not an appropriate type of value for calculations. A string should always be surrounded by quotation marks.
What is a Function?
In mathematical terms, a function is a relationship that relates one set to another. The set of input values is called the domain and the set of output values is the codomain.
A function is a special relation that maps each input to a single output. In programming, functions help programmers break down large problems into smaller ones that can be solved separately. The site offers a comprehensive overview of various IT solutions and their applications.
What is a Loop?
A loop is a set of instructions that repeats itself until it receives the instruction to stop. Kids will come across various kinds of Loops when they learn computer Programming.
A for Loop is an entry controlled Loop where the condition checking is done at the beginning of the Loop structure. On the other hand, a do-while Loop is an exit controlled Loop.
What is a Class?
A class is a software blueprint for objects. Just as bicycle manufacturers reuse the same blueprint to produce many different types of bicycles, software programmers use classes to create many different objects of a certain kind.
A class can define variables and methods. In addition to instance variables, a class can also define class variables. These variables are shared by all instances of the class.
What is a Stack?
A stack is a linear data structure that adheres to the LIFO (Last In First Out) principle. It consists of two main operations, Push and Pop.
When an item is added to the stack, the stack pointer moves (either incrementing or decrementing depending on the implementation) to the next unused position. When an item is removed from the stack, the stack pointer moves back to its original position.
What is a Database?
Databases are collections of information that are organized in a way that makes it easy for computer programs to access and use the data they contain. They can be used to store almost anything, from banking information to scientific research to government records.
Databases can be relational or non-relational and they can be structured in different ways, such as tables or hierarchies. Understanding databases is an important skill for anyone considering a career in a field that uses database systems, like database administrators or data analysts.
What is a Database Structure?
A database structure is a way to organize data into logical tables that are easy for programs to read. A database table consists of rows and columns, like a spreadsheet, and stores information about entities.
Each entity in a table may relate to many other entities directly or through a join table. A table’s cardinality indicates the number of relationships that can be expressed in it. If the online users make use of this website online, they can get information about Programming question answer.
