To begin with, we must go back to history, as it is said, the first smartphone was created by IBM in 1992 and was called Simon, but was released in 1993 and was marketed by BellSouth, then the smartphone allowed you to do many things, that is, receiving and making calls, had a calendar, address book, world time, notepad, sent and received FAX.

When did the first smartphone come on the market?

Uniting PDA and mobile phone. For many the first smartphone (again, without that name) of the story was the IBM Simon Personal Comunicator, whose prototype appeared in 1992 and whose sale began in 1994

¿How does a smartphone work?

A smartphone is another term used to refer to a personal digital assistant. This is a device that has a color screen and combines the features of a laptop and a mobile phone. It also has the ability to connect networks wirelessly and send electronic messages.

!Operating system¡

A smartphone has to have an operating system to function. The type of system used often depends on the phone model. For example, the iPhone uses a system designed by Apple, while Microsoft uses Windows Mobile for its mobile market. Even open source systems such as Linux can be used on a smartphone. What differentiates a smartphone from regular computers is that it needs to connect with a mobile phone service provider to send and receive data.

technology

Because a smartphone must connect with a service provider, it also makes use of the digital radio technology used by most mobile phones. The device works because the information is transformed into binary data, which is a series of ones and zeros that are compressed to facilitate transmission. A smartphone is capable of handling the amount of information it contains, since it makes use of a technology called FSK, which uses two frequencies. Each frequency is completely dedicated to a particular number of the binary series and is exchanged from one or zero to send the digital signal from the telephone to the transmission tower.

Memory

The way a smart phone stores information is vital to its operation due to the large amounts of data it has to deal with. It usually has an internal memory and is complemented by a flash memory. The latter is an external device that is used for additional space to contain the information stored on the smartphone. A flash memory is similar to a hard drive in a normal computer and makes use of electronic signals to create a binary series, which is used to represent the stored data. The electrons that are in the flash memory receive a charge of electricity to show a value of one. If a cell sensor on the memory card detects that the load is below 50 percent of its capacity, then the value assigned to the information is a zero.

Battery

A smartphone works by getting its power from a rechargeable battery. A battery is discharged when the electrons move from negative to positive locations. In a rechargeable battery, electricity is used to transfer the electrons back to their places of origin. The speed at which a smartphone restores its power depends on the amount of electric current that the charger allows it to flow.

Characteristics of a SmartPhone

Of course, it allows you to make phone calls.

- It has GPS.
- Allow the installation of third-party programs.
- Use any interface for data entry, such as QWERTY keyboard, touch screen.
- They allow you to enter the Internet with 4G technology.
- Wireless connectivity such as Wi-Fi.
- They have a digital agenda, contact management.
- Allow to read documents in different formats, including PDFs and Microsoft Office files
