Tech Terms Decoded 50 Essential Tech Terms Every Sdet Must Know

Contents

Tech terminologies are words or a set of words that are used in technical fields. One of the fields where technological terminologies are used widely is IT. These terms can be any word that has a specialized meaning. For newcomers in any field, it is beneficial to know the terminologies as they aid in communication among colleagues and professionals. This blog will discuss many of the terminologies used in IT sectors for newcomers helping them to fit in the environment.

1- Algorithm

A collection of instructions or rules provided to accomplish a particular task or address a category of problems or computations. The main purpose that an algorithm serves is data processing and performing calculations. Due to recent advancements in AI, the utilization of algorithms has witnessed a notable increase.

2- Software

Software is a general term for different kinds of programs that tell the computer to perform specified tasks. A software can be a system software or an application software. Each software consists of user manuals for users on the functioning of the software.

3- Hardware

Computer hardware consists of the actual components of a computer. The components of the computer i.e. casing, central processing unit, random access memory, monitor, mouse, keyboard, hard drive, and motherboard. These components store and execute the set of instructions that a software constitutes.

4- Programming Language

A formal system used to instruct computers, such as Python, Java, or C++. Each programming language consists of syntaxes and semantics and each language has its properties and functioning.

5- Code

Code is simply words or phrases written in a programming language that a computer can execute. In communication and information processing, a code is a set of rules converting information into a different form, often abbreviated, or encrypted, for transmission through a channel or storage in a medium.

6- Database

A database is a collection of organized information or a type of data repository that works with a database management system. This software interacts with end users, applications, and the database to capture and propose information. The purpose of a database is also to secure information and retrieve it again.

7- Cloud Computing

Cloud computing refers to the immediate accessibility of computer system resources. It aids in accessing data storage and computational capacity without direct user intervention. Extensive cloud networks frequently distribute functions across various locations with each serving as a data centre.

8- Cybersecurity

Computer security, also known as cybersecurity, involves the safety of computing systems and networks against malicious attacks or unauthorized access. These malicious attacks could lead to the disclosure of unauthorized information, theft, or damage to hardware, software, or data. Additionally, it aims to avoid any interference or misdirection of the services offered by these systems.

9 – Encryption

Encryption is the procedure of transforming information and converting the plaintext into an alternative form termed ciphertext. Only authorized parties can decipher ciphertext back into plaintext while ensuring access to the original information.

10 – API

An application programming interface (API) serves as a mechanism for two or more computer programs or components to communicate effectively. It provides a service to other software components functioning as a software interface.

11- HTML

Hypertext Markup Language (HTML) serves the purpose of the conventional markup language for creating and designing web pages. As a markup language, it documents things intended to be presented in a web browser. It sets out the content and structure of web content and is frequently complemented by technologies like Cascading Style Sheets and scripting languages such as JavaScript.

As a markup language, it’s used to write things meant to be shown on a web browser.

12- URL

A Uniform Resource Locator (URL) is like a web link and shows where something is on the internet and how to get it. The most used terminologies used by people are URL and web address interchangeably.

13- Cache

Cache is a storage space in either hardware or software that keeps information, helping to quickly provide data when it’s requested again, making things faster. The data in a cache could be from a previous calculation or a copy of information saved in another place. In general, we can say that temporary storage helps to retrieve data quickly, reducing the need to access the source cache.

14- Artificial intelligence

Artificial intelligence is the enchanting realm where machines and software collect a form of intellect, distinct from the intelligence found in humans. Artificial Intelligence unfolds as an art exploring the intricacies of intelligent machines.

15- Machine Learning

Machine learning, which is a field of study in computer science and artificial intelligence, concentrates on developing and studying statistical algorithms. These algorithms learn from data and, akin to humans, refine their accuracy over time. This enables them to perform tasks without explicit instructions.

16- Deep Learning

Deep learning is a segment of machine learning and artificial intelligence that utilizes artificial neural networks with multiple layers for representation learning. It replicates the human brain’s ability to process data and enables systems to autonomously learn, identify patterns, and perform intricate tasks with increased accuracy and as a result, reduce the need for human intervention. This approach makes deep learning a powerful method inspired by human cognitive processes.

17- Metadata

Metadata is information about other data, not the content of the data itself, such as the text of a message or the image. It serves as a structured reference, aiding in the sorting and identification of attributes associated with the described information. This provides details about a resource, offering context about the source, type, owner, and relationships.

18- Blockchain

Blockchain is an advanced database mechanism in a business network, providing a collective and unchangeable ledger for documenting transactions and monitoring assets. It enables transparent information sharing, with data stored in interconnected blocks forming a chain. Whether tangible or intangible assets, almost anything of worth can be monitored and exchanged on a blockchain network, reducing risks and costs. The chronological consistency of the blockchain database ensures an unalterable ledger for tracking various transactions, offering security and decentralization beyond its role in cryptocurrency systems.

19- IoT

The Internet of Things (IoT) deals with devices that have processing abilities, sensors, software, and other technologies. These devices connect and exchange data with other devices and systems using the Internet or other communication networks. IoT comprises a combination of electronics and networking engineering

20- Operating System (OS)

An operating system is software that manages computer hardware and provides services for computer programs. It acts as an intermediary between users and the computer hardware, facilitating communication and execution of tasks.

21- Firewall

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier to prevent unauthorized access and protect against potential cyber threats.

22- VPN (Virtual Private Network)

A VPN is a technology that creates a secure, encrypted connection over a less secure network, such as the Internet. It allows users to access private networks and share data remotely while maintaining confidentiality and security.

23- Server

A server is a computer or system that provides services, resources, or data to other computers, known as clients, over a network. Servers can handle various tasks such as hosting websites, managing emails, or storing files.

24- Bug

A bug is a programming error or flaw that causes a software program to behave unexpectedly or produce incorrect results. Debugging is the process of identifying and fixing bugs in a program.

25- Interface

 An interface is a point of interaction between different software components or between a user and a computer system. It defines how users or programs can interact with and utilize the features of a software application
