Email addresses using a private domain are typically accessed through a webmail service provided by that domain (such as mymail.example.com). Webmail allows users to send and receive emails using a web browser without needing a dedicated email application.

The word 'computer' is derived from the Latin word 'computare,' which means to calculate or to count. Thus, its origin is the Latin language.

Typing speed is commonly measured in Words Per Minute (WPM), which indicates how many words a person can type in one minute.

Twitter was officially launched in 2006, making it the correct answer. The platform was developed by Jack Dorsey and others and became publicly available that year.

HTTP stands for Hypertext Transfer Protocol, which is the foundational protocol used for transmitting data on the World Wide Web (WWW). It enables communication between web browsers and servers.

A WAN (Wide Area Network) covers a large geographic area, and mobile broadband connections are a typical example because they connect devices over long distances using cellular networks. The other options describe local networks, not WANs.

RAM stands for Random Access Memory, which is a type of computer memory that can be accessed randomly. This allows data to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.

Ctrl + Y is a common keyboard shortcut used to redo an action that was previously undone, especially in Microsoft Office and many other applications.

PROM stands for Programmable Read-Only Memory, which is a type of non-volatile memory that can be programmed once after manufacturing.

CRT stands for Cathode Ray Tube, which is a type of display technology used in older monitors. Therefore, CRT is a form of display monitor.

HTML (HyperText Markup Language) is the standard language used to create and structure webpages on the internet.

LAN stands for Local Area Network, which refers to a network that connects computers within a limited area such as a home, school, or office building.

HTML stands for Hypertext Markup Language, which is the standard language used to create and design web pages.

Social networks are primarily organized around people, as they are platforms designed to connect individuals and facilitate social interactions.

Ray Tomlinson is widely recognized as the inventor of email and is often referred to as the 'father of email' for implementing the first networked email system in 1971.

CPU stands for Central Processing Unit, which is the main component of a computer responsible for executing instructions and processing data.

USB stands for Universal Serial Bus, which is a standard for cables, connectors, and protocols used for connection, communication, and power supply between computers and electronic devices.

Cache memory is a small, high-speed memory located on or very close to the CPU. It stores frequently accessed data and instructions to speed up processing.

TCP stands for Transmission Control Protocol, which is a core protocol of the Internet protocol suite. It provides reliable, ordered, and error-checked delivery of data between applications.

CPU stands for Central Processing Unit, which is the primary component of a computer that performs most of the processing inside a computer.

In computer architecture, 'CU' stands for 'Control Unit,' which is a component of the CPU responsible for directing operations within the computer.
