- Computer
The Answer:
And, the answer for the the question is :
Explanation:
For the majority of the phone’s existence, it was impossible to make a direct call from one person to another. Instead, a third party operator would use a switchboard to connect callers. Prior to the 1930s, when technology was developed to eliminate the need for operators, approximately 235,000 individuals in the United States were employed in the telephone industry.
The world we live in today is characterized by the widespread use of mobile phones, which have become an integral part of our daily lives. However, it is easy to forget that this was not always the case. In fact, it was just a few decades ago that the first cell phone was invented, revolutionizing the way we communicate and paving the way for the modern smartphone. And the company behind this groundbreaking invention was none other than Motorola.
Motorola, a telecommunications company founded in 1928, had been at the forefront of the development of mobile communication technology for many years. In the 1940s and 1950s, the company was responsible for the development of radio communication systems used by the US military. However, it was in 1973 that the company made its biggest breakthrough with the invention of the world’s first cell phone.
The first cell phone, known as the Motorola DynaTAC 8000X, was a large and heavy device that weighed almost 2 pounds and cost $3,995. It was not exactly a practical device for everyday use, but it was a major step forward in the development of mobile communication technology. The DynaTAC was able to make and receive calls, and it had a battery life of around 30 minutes.
the DynaTAC was a game-changer. It was the first time that people could make phone calls without being tethered to a landline, and it paved the way for the development of smaller and more affordable cell phones. Over the next few decades, Motorola continued to innovate in the field of mobile communication technology, releasing a range of new devices that were smaller, lighter, and more sophisticated.
In the 1990s, Motorola released the StarTAC, which was the first flip phone and became one of the most popular cell phones of the decade. Then, in the early 2000s, Motorola released the iconic Razr, which was one of the thinnest and most stylish phones of its time. The Razr became an instant classic and helped to cement Motorola’s reputation as a leader in mobile communication technology.
Motorola is still a major player in the mobile phone industry, although it faces stiff competition from other companies such as Apple and Samsung. Nevertheless, the company’s contribution to the development of mobile communication technology cannot be overstated. The invention of the first cell phone was a major milestone in the history of communication, and it was all thanks to Motorola’s innovation and vision.
