The telephone and cell phone are important to everyday life. The cell phone makes it easier to communicate with others when they are farther away.
Before the telephone was introduced, it was harder to spread information, many historical figures had to use letters and wait multiple weeks/months for news to arrive. This was crucial time especially during wars because these historical figures had no way of knowing of important news until after waiting for it.
Once the telephone was introduced, many people were able to tell others information quickly. This invention helped others to call and inform others of things faster. Historical figures used this invention during harsh times to connect with each other faster than they used to.
Today, however, we use cell phones for everything. Cell phones are the highlight of connection for many younger and older generations today. We use cell phones to connect with others, inform each other of news, play games, call each other, and have fun. The cell phone is now a versatile and vital aspect of everyday life.
In conclusion, the cell phone and telephone has helped every aspect of communication, allowing everyone in the world to connect over thousands of miles away.
