In today's society, communications play a very important role, since it allows us to continuously communicate and interact with other people and companies. It could be said that without communications life would not be as we know it. Over time, the need to communicate became ever greater, which is why companies and manufacturers sought to evolve and offer more and better equipment and services to users. But the evolution of mobile phones begins in 1972 when Martin Cooper turned the phone into an artifact that was impossible to get rid of.
These devices altered the way in which people communicate, as well as their social behavior. Over the years, mobile phones have evolved and continue to do so dramatically. They started out just as analog “bricks” (named for their shape and size), and are now small, digital, and feature-rich devices.
The first mobile phone
The first mobile phone was the Motorola DynaTAC 8000x which appeared was launched on the market in 1983. It weighed 780 grams and had dimensions of 33 x 9 x 4.5 cm. It was an analog phone with a tiny screen. The battery had a life of no more than one hour of conversation and 8 hours of standby.

The sound quality of this phone was very poor, it was a heavy device and with little aesthetics. However, some people came to buy it for a price of $ 3,995, becoming a luxury item.
As expected, the people in using them were entrepreneurs, executives and people with a lot of money to buy it. Since the economic development of a company requires effective communication with employees, suppliers, customers, governments and regulatory agencies. This service had a high cost and since there was no competition in the market, prices did not drop.
First-generation of mobile phones
The first generation begins with the Motorola DynaTAC 8000X in the 1980s. These devices were analog technology for use by voice commands. The technology of this generation was AMPS (Advanced Mobile Telephone System).
The second generation of mobile phones
In the 90s, new mobile phones with digital technology emerged and benefits were highly valued. They had longer battery life, more definition and a significant improvement in sound quality. These phones had a new function, they were able to send and receive text messages (SMS), although it had not yet become popular.
Ordinary people became part of the user list, as prices were reduced by competition between companies. The dominant technologies were GMS, CDMA and PDC. The latter was only used in Japan.
Second generation phones operated under GMS, CDMA and PDC technologies. They were also able to send text messages (SMS).
The third generation of mobile phones
This generation had the incorporation of old technology but with a new design. These phones reached many more users, mainly due to lower prices. It was also the appearance of the SIM card, where all the information of the device line is located.
Consumption became large, mainly due to the low prices and very good promotions. However, social status still existed and the mobile phone has a certain symbolic value of class membership.
The third generation of phones appeared with the SIM card, which had all the information on the line. These were already devices capable of capturing photographs, filming a few minutes, color screens, fast Internet connection, multimedia messaging and email mailbox.
Users already had an infinite market for mobile phone models that even incorporated digital cameras. These were devices capable of capturing photos, filming a few minutes, color screens, a fast Internet connection, multimedia messaging and an email box.
In Japan, UMTS-based 3G mobile phones were launched. The main change was that a second (front) camera was added to make video calls so that you could see and talk to a person at the same time as the mobile phone. After this, other communication standards appeared, making them faster and more functional.
Smartphones, the fourth-generation mobile phones
The 4G communications changed completely and forever the way in which people use their phones. The smartphone or Smartphone was basically a union between a phone and a computer, breaking the pattern of content consumption that we have used for years.
Fourth-generation phones are devices that changed things. These smartphones are capable of transmitting at high speeds, you can even view content in high definition.
The 4G transmission speed allows us to view HD content, music streaming and more. And of course, if something has to do with work, everything is done much faster and without complications.

The evolution of computers until today
Computers have been around much longer than you thought, and their meaning has changed for decades. In fact, the electronic computer we have in mind was developed in the middle of the 20th century. But it didn't become popular for home consumption until the 1980s, after the advent of Microsoft and Apple operating systems that combined text and graphics. This replaced the text-only systems of the 1970s. Later, in 1990, computers already had improved multimedia and communication applications, making them indispensable for the daily life of many people. You want to know more? Here we tell you about the evolution of computers and their history until today.
What is a computer?
To know the evolution of computers, the first thing you should know is that the original definition of "computer" was a person who performed calculations. This definition is from the 1600s and runs until the mid-20th century when "computer" began to refer to a machine.
The computer is based on the same concept as the abacus, which dates back centuries. Technology made a major leap with punch cards, developed by Joseph-Marie Masquard in 1801. In fact, this system was even used to involve music, where piano coils assigned actions to notes on a piano. In 1835, Charles Babbage combined punch cards with a steam engine to invent a "the analytical machine. "

Mechanical information processing
Later, in 1880 the IBM company arose from the invention of the tabulator, which was developed by Herman Hollerith. This was the first use of punch cards that represented data rather than automating a mechanical function. So, the information processing world of the 1950s was based on a combination of tabulator, punch card, and punch machine.
The first calculators appeared in the 1930s. These analog machines began to be replaced by the digital concept of 0 and 1 at the time of World War II. The first computer developed was UNIVAC, developed by Remington Rand in 1951. Then IBM introduced its mainframe computer model a year later.
Computer integration
Each Remington computer went on to sell for more than a million dollars, however, IBM took advantage by selling smaller, more affordable machines. In 1954, IBM developed Fortran which is an original mathematics-based computer programming language . In this same decade, transistors, microprogramming and integrated circuits were developed that allowed reducing the size of a computer.
At the same time, the CPU and storage memory were improved, allowing a higher processing speed. Then, in the 1970s, thanks to Intel and Texas Instruments, the first microprocessors arrived. This allowed for much smaller and much more powerful computers.
Who had access to a PC?
Until the 1970s, computers were primarily used by universities, governments, and large companies. It wasn't until the end of that decade that personal computers first appeared. Apple introduced the Apple I in 1976 and the Apple II in 1977, ushering in an era of home computers.
Apple IIGS.
From that moment, the software industry began to be born, with Apple and Microsoft being the most important. Microsoft gained popularity by marketing its DOS operating system on IBM computers from 1984. While Apple released Macintosh in 1984, it featured graphics and text, replacing machines that only displayed text. From this moment, Apple has called its system "Mac" to differentiate it from the rest of personal computers.
A multimedia machine
In the 1990s, the computer was already too popular, being a common device in homes. Microsoft's Windows 95 system caused its use of computers to grow, as the World Wide Web caught the attention of shoppers.

Almost all professions would already need a personal computer to improve services and products. In the first decade of 2000, Microsoft introduced its versions of Windows XP and Vista, while Apple offered OS X Leopard. These operating systems combined with popular software meant that users had access to very large multimedia tools.
