Tags appear in websites, social media platforms, programming languages, databases, and file management systems. HTML tags are especially important in web development.
Taskbar
The taskbar is a user interface element commonly found in operating systems such as Microsoft Windows.
It usually appears at the bottom of the screen and provides quick access to open applications, notifications, settings, and system tools.
TCP/IP
TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol.
It is the foundational communication system that allows devices to exchange information across the internet and computer networks. Modern internet communication depends heavily on TCP/IP protocols.
Telemetry
Telemetry refers to the automatic collection and transmission of data from remote systems or devices.
It is widely used in industries such as healthcare, aerospace, automotive engineering, cloud computing, and smart devices.
Teleconference
A teleconference is a meeting conducted remotely using communication technology.
Modern teleconferencing often includes video calls, screen sharing, chat functions, and collaborative online tools. Platforms like Zoom and Google Meet popularized teleconferencing worldwide.
Telehealth
Telehealth refers to healthcare services provided through digital communication technologies.
Doctors and healthcare professionals can conduct consultations remotely through video calls, apps, and online systems.
Terabyte
1\ \text{Terabyte} = 1024\ \text{Gigabytes}
A terabyte is a unit of digital storage capacity.
Modern computers, cloud storage services, gaming systems, and external drives frequently use terabytes to measure storage space.
Terminal
A terminal is a text-based interface used to communicate directly with a computer operating system.
Developers, system administrators, and programmers commonly use terminal windows to execute commands and manage systems efficiently.
Text Editor
A text editor is software used to create and edit plain text files.
Popular text editors include Visual Studio Code and Notepad++. Text editors are especially important in programming and web development.
Thread
In computing, a thread is a sequence of executable instructions within a program.
Modern software often uses multithreading to improve performance by allowing tasks to run simultaneously.
Throughput
Throughput measures how much data can move through a system or network within a certain period of time.
Higher throughput generally means better performance in networking and computing environments.
Thumbnail
A thumbnail is a small preview image representing a larger image, video, or file.
Thumbnails are commonly used on websites, video platforms, galleries, and file explorers to improve navigation and visual organization.
Thunderbolt
Thunderbolt is a high-speed hardware connection technology developed for transferring data, video, and power.
It is commonly used with laptops, monitors, storage drives, and professional creative equipment.
TLS
TLS
TLS stands for Transport Layer Security.
It is a security protocol that encrypts internet communication to protect sensitive data such as passwords, payments, and personal information.
Toggle
A toggle is a switch or control that changes between two states, such as on/off or enabled/disabled.
Toggles are commonly used in apps, software settings, websites, and user interfaces.
Token
In technology, a token often refers to a digital credential or authentication key.
Tokens are widely used in cybersecurity, APIs, blockchain systems, and login verification systems.
Toolbar
A toolbar is a graphical section within software containing buttons, shortcuts, or tools.
Toolbars help users access frequently used functions more efficiently.
Torrent
A torrent is a file-sharing method that distributes data across peer-to-peer networks.
Torrent systems allow multiple users to share portions of files simultaneously rather than relying on a single central server.
Touchpad
A touchpad is a flat input device commonly found on laptops.
It allows users to control the cursor using finger movements instead of a traditional mouse.
Touchscreen
A touchscreen is a display that responds to touch input.
Touchscreen technology is widely used in smartphones, tablets, kiosks, gaming systems, and modern laptops.
TPM
TPM
TPM stands for Trusted Platform Module.
It is a hardware-based security feature designed to protect encryption keys and improve device security.
Traceroute
Traceroute is a networking diagnostic tool used to track the path data takes across networks and the internet.
IT professionals often use traceroute to troubleshoot connection issues and analyze network performance.
Transformer
Transformer refers to a machine learning architecture widely used in artificial intelligence.
Transformer models power many modern AI systems, including chatbots, translation systems, and generative AI tools.
T9
T9
T9 was a predictive text technology used on older mobile phones with numeric keypads.
T9 helped users type messages faster before touchscreen smartphones became common.
Trojan Horse
A Trojan horse is a type of malicious software disguised as legitimate software.
Cybercriminals may use Trojans to steal information, damage systems, or gain unauthorized access to devices.
