Bandwidth refers to the amount of data that can be transmitted over a network or Internet connection in a given period, usually measured in bits per second (bps). It indicates the speed and capacity of a connection, with higher bandwidth allowing more data to be transferred at once. In simple terms, bandwidth is like the width of a pipe through which data flows—larger bandwidth means more data can pass through quickly. Bandwidth is important for activities like streaming videos, playing online games, or downloading files, as it affects how smoothly these tasks can be performed.

An IP address, or Internet Protocol address, is a unique string of numbers assigned to each device connected to a network, such as the Internet. It allows devices to identify and communicate with each other by providing an address for sending and receiving data. There are two types of IP addresses: IPv4, which consists of four sets of numbers, and IPv6, a newer version with a longer address format to accommodate more devices. An IP address is essential for browsing the web, sending emails, and using online services.

A carrier is a company that provides cellular or Internet services to customers. They manage the infrastructure and networks that allow people to make phone calls, send texts, and access the Internet. Carriers offer different types of plans for mobile and broadband services, including data, voice, and text messaging options. They also ensure that customers can connect to the Internet or use mobile services wherever they go, often through a combination of local and global networks.

CC stands for "carbon copy" and is used in emails to send a copy of the message to additional recipients beyond the main one. When someone is added in the CC field, they will receive the email, but they are not the primary person intended for the message. CC is often used to keep others informed or involved in a conversation without directly addressing them. The recipients in the CC field can see the email addresses of everyone included, allowing for transparent communication.

A feed refers to a feature on a website that allows users to receive updates automatically about new content or changes without having to visit the site. It delivers the latest information, such as news articles, blog posts, or social media updates, directly to the user, often through a dedicated app or news tracker. This feature keeps users informed and saves time by providing new content in a convenient, easily accessible format whenever it is updated.

A hotline is a direct phone line that provides immediate assistance or support for specific issues, such as emergencies, mental health crises, or customer service concerns. It is often available 24/7, ensuring that people can receive help at any time. Hotlines are typically operated by trained professionals who are ready to offer advice, support, or direct assistance. They are commonly set up by government agencies, non-profit organizations, or businesses to address urgent needs and offer quick responses to critical situations.

Cold-calling is the practice of making unexpected phone calls to potential customers or clients, typically with the goal of selling a product or service. These calls are often made without prior contact or a request from the person being called. Cold-calling is commonly used in sales and marketing, but it can be seen as intrusive, as the person receiving the call has not expressed interest in the product or service. Despite this, cold-calling remains a strategy used by many businesses to generate leads and expand their customer base.

A landing page is a specific web page designed to direct visitors toward a particular action or goal, such as signing up for a newsletter, making a purchase, or learning more about a product or service.

Landing pages are usually focused and simple, with clear instructions on what to do next and minimal distractions, helping guide visitors to complete a specific task. They are commonly used in marketing campaigns to increase conversions or gather leads.

A thread is a series of connected messages or posts about a particular topic. It can include an original message or post along with any responses or related updates, though not all threads have replies. Threads are commonly found on social media platforms, in email chains, or in messaging apps, helping to organize conversations and keep all related content grouped together. This allows users to easily follow a discussion or track information about a specific subject.

A troll on social media is a person who deliberately posts rude, upsetting, or offensive comments or content to provoke others and create conflict. Trolls typically seek attention or enjoyment by upsetting people, starting arguments, or disrupting conversations. Their actions can include insulting others, spreading misinformation, or making offensive remarks. The goal of a troll is often to get reactions from others, causing frustration or distress. Social media platforms may have tools to block or report trolls to limit their negative impact.
