The spelling of "external hub" is straightforward when you understand IPA phonetics. "External" is pronounced /ɪkˈstɜː.nəl/ (ik-stur-nuhl), with emphasis on the second syllable, while "hub" is pronounced /hʌb/ (huhb) with a short vowel sound. The combination of these two words gives us "external hub", a term used to describe a device that connects multiple peripherals to a computer or other electronic device. This type of hub is an external attachment rather than an internal component, making it easy to plug and unplug devices as needed.
An external hub refers to a device or component commonly used in computer systems and networks to expand the number of available ports for connecting peripheral devices. It serves as an intermediary device enabling multiple devices to be connected to a single port, usually a USB (Universal Serial Bus) port, on a computer or another hub.
Essentially, an external hub acts as a distribution center, allowing users to connect numerous peripherals simultaneously without modifying computer or network infrastructure. By accommodating multiple connections, it eliminates the need for constantly swapping cables and aids in organizing various devices. These hubs are typically small, lightweight, and portable, making them convenient for use in various settings.
Commonly, external hubs are equipped with multiple ports, which can support devices such as keyboards, mice, printers, scanners, external hard drives, digital cameras, and other USB-enabled devices. They can also be cascaded or daisy-chained, meaning one hub can be connected to another hub, thereby expanding the number of usable ports exponentially.
External hubs are an essential part of modern computer setups as they simplify the expansion and integration of peripherals, enhancing connectivity and accessibility. They provide a convenient and efficient means to connect multiple devices, simplifying the overall user experience.
The term "external" comes from the Latin word "externus", which means "outer" or "outside". The word "hub" originated in Middle English from the Old English word "hubb", which referred to the central part of a wheel from where the spokes radiate.
So, the etymology of the term "external hub" is a combination of these two words. "External" describes something that is located on the outside or outer surface, while "hub" refers to a central point or connection point. When used together, "external hub" typically refers to a device or component that is connected externally to a central system or serves as an interface between external devices and a primary system.
