Digital Communication

Broadband is a high-speed Internet connection that provides fast and continuous access to the Internet. It can carry large amounts of data simultaneously, allowing for activities like streaming videos, browsing websites, and downloading files without interruptions. Broadband is available through different technologies, including fiber-optic cables, cable, and wireless connections. It offers much faster speeds compared to older Internet connections, like dial-up, and is essential for modern digital services, providing reliable Internet access for homes, businesses, and other users.

An emoji is a small digital image or icon used to express emotions, ideas, or reactions in online communication. Emojis are commonly used in text messages, social media posts, or chats to add emotional context, emphasize a point, or make conversations more engaging. They can represent facial expressions, objects, animals, activities, or symbols. Emojis help make text-based communication more expressive and fun.

An emoticon is a textual representation of a facial expression created using keyboard characters to convey emotions in written communication. For example, a smiley face is represented as :-) or :) to indicate happiness, while a sad face can be shown as :-( or :( to express sadness. Emoticons are commonly used in informal settings, such as texting and online messaging, to add emotional context to messages that might otherwise be misunderstood. They help convey tone and sentiment, making conversations more engaging and expressive. While emoticons were popular in the early days of digital communication, they have largely been replaced by more complex emojis that provide a wider range of expressive options.

A payphone is a public telephone that requires the user to pay in order to make a call. Typically, users insert coins, tokens, or a prepaid card into the machine to cover the cost of the call. Payphones were commonly found in public spaces such as streets, airports, bus stations, and shopping centers, providing an option for communication when people were away from their personal phones. While their use has declined with the widespread availability of mobile phones, payphones are still available in some places, especially in emergencies or locations with limited mobile coverage.

A telegraph is an old communication device used to send messages over long distances by transmitting electrical signals through wires. The signals were typically sent in the form of Morse code, which could be decoded into text by the receiver. Telegraphs were widely used in the 19th and early 20th centuries for fast communication, especially for business, military, and emergency purposes. They played a crucial role in connecting distant places and reducing the time it took to send information. The advent of telephones and the Internet eventually replaced the telegraph.

A fax, short for facsimile, is a device used to send and receive documents over a telephone line. It works by scanning a physical document, converting it into a digital signal, and transmitting it to another fax machine, which prints a copy of the document. Fax machines were widely used in offices and businesses to send contracts, forms, and other documents quickly and securely. While less common today due to digital communication methods, fax machines are still used in some industries that require signed or legally binding documents to be sent in their original form.

A teleconference is a meeting or discussion held over the phone or via the Internet, where participants in different locations can communicate with each other in real time. It allows people to join a conversation or meeting without needing to be in the same physical place. Teleconferences are commonly used for business meetings, presentations, or group discussions, and they can include voice-only calls or video conferences, where participants can also see each other. This method of communication helps save time and travel costs while making collaboration easier.

A selfie is a photograph that a person takes of themselves, usually with a smartphone or camera held at arm's length or with the help of a selfie stick. Selfies are often shared on social media platforms and are commonly used to capture moments, express personal style, or communicate with friends and followers. The focus is typically on the person taking the photo, capturing their face and sometimes part of their surroundings.
