What is a pocket computer?
Pocket computer is a compact electronic device that is programmable in one or more standard computing languages. Pocket computers have used many available technologies of their era, including miniaturized processors, mobile phones and telecommunications and external data storage functions. Although they have been widely available in the last two decades of the 20th century, pocket computers were mainly used by scientists and technology lovers. However, pocket computers promoted many progress in portable calculations. These advances have gained expanded use in the following years with the introduction of portable digital assistants (PDA) and smartphones.
The oldest computers were huge devices; In the mid -20th century, processors filled the entire rooms and could only perform simple tasks. Advances in technology, including miniaturization of circuits and processors, allowed the creation of home computers of the first table in the 70s. In the following decade, ambitious technology companies introduced pocketComputers, a manual device that was previously seen only in sci-fi. Their high costs and limited usefulness for everyday functions meant that they had never had a widespread success of personal computers or mobile phones. In the 21st century, the pocket computer was only an interesting relic of the early age of the computer.
Most handheld computers operated on standard computer programming languages such as DOS or Basic. Some included telecommunications functions and could send and receive faxes or double as mobile phones. Their memories were small according to later standards; Many of them required external data storage devices, such as a cassette tape unit. Despite the name, pocket computers were often bulky, even if they could be closed and folded if they are not used for storage or transport. Some models included touch screens, which is a procedure thatwould be Wiz employed in later facilities.
As the 21st century, the pocket computer was replaced by more advanced technological devices such as PDA. This device included many pocket computer functions, along with the features of home computer and laptop that decreased and advanced with each generation. The last pocket computer was sold to the public in 1998. Less than ten years later, the first smartphone was introduced; This device was smaller than a pocket computer, but could perform many tasks that previously required desktop computers. This combination of size and functionality has made the smartphone a widespread and influential success around the world.
Some pocket money owners still use their devices long after they have ceased to be produced and on the market. Even these users eventually moved to a more efficient device such as PDA and smartphones. In a sense, these are also pocket computers, although the term usual refers only to the older assignmentthe eating. Pocket computers can still be seen in the movies and television shows of the era. For example, a scientist who played Harold Ramis in 1984, Ghostbusters uses a handkerchief in some scenes.
