Portable equipment is electrical equipment that can be readily transported from one location to another while in use or connected to a power source. Some examples of portable equipment include cellular phones, laptops, and handheld video games. Portable equipment is used many times during daily life. For example, people use portable telephones when they go for walks or rides, and laptop computer users carry their computers with them in cars, on trains, and in buses.
Electricity is the flow of electrons through a conductor such as a copper wire. Electric circuits inside equipment operate because electrons are added to or removed from the ends of the conductors connecting parts of the equipment together. The electrons travel along the conductors, which act as pathways for electrons to follow between connections at either end. A circuit may have one conductor coming into contact with several other conductors, each of which connects to more terminals, thus allowing the circuit to connect different components together. The term "portable" refers to the ability of the equipment to be moved from place to place without having electricity stopped to it for use or storage.
As well as being useful when you are out and about, portable equipment is also necessary when you are in remote areas without access to mains power.
A portable device is any device that can easily be carried. Portable devices are becoming an increasingly important part of personal computing as the capabilities of devices like laptops, tablets, and smartphones continue to improve. A portable device may also be called a handheld device or mobile device. Handheld devices are typically less than 10 inches diagonally while mobile devices are usually larger than 10 inches.
Portable devices are very useful because they allow us to take our work with us wherever we go. You can use a portable device in place of a desktop computer for certain tasks such as creating documents, emails, and presentations. Some popular portable devices include iPad, iPhone, Android phones, and Windows tablets.
Although these devices are convenient, they do have some limitations. For example, most portable devices have small screens which make reading text difficult. Also, it can be difficult to interact with several programs at once on a portable device since each program must have its own screen. Finally, many portable devices are battery powered, so there is a limit to how long they can operate without a recharge.
Some people prefer using portable devices to full-size computers because they are easier to carry around and do not take up much space. However, portable devices have their limitations too so it's best to choose what tasks you need to perform and then use the right tool for the job.
As the capabilities of devices such as laptops, tablets, and smartphones continue to develop, portable devices are becoming an increasingly significant aspect of personal computing. A portable device is sometimes referred to as a handheld device or a mobile device. These terms are generally applied to referring to devices that have a large display screen and that can be carried around by the user.
A typical portable device includes a body and a lid which rotates relative to the body between open and closed positions. When in the closed position, the lid attaches to the body with hinges such that the body and lid form a single unit. The body may include input devices such as a keyboard for text entry, a mouse for cursor control, and/or a touch screen for image input. The lid may include a display panel for visual output. The display panel may be an LCD panel or a CRT panel. Hearing output can be provided through a speaker system integrated with the body or through headphones that connect to the lid. A network connection interface may be included on the body to allow the portable device to be connected to a network.
Portable devices are widely used for communication purposes as well as for information processing. They are often considered as a replacement for other desktop computers because of their mobility and capability of information processing. Portable devices are also used as entertainment devices because of the availability of many video games and media players.
