In this Assignment I will be providing an overview of four technological developments from prehistoric times. The Gas Mask: The primary purpose of a gas mask is to prevent deadly gases or poisonous material from accessing the lungs and attacking the person.

Machine Guns: Until the machine gun was created, we only had rifles which was slow. You could only shoot one bullet at a time and then you had to load another bullet into the chamber using the bolt. When you used the bolt, it would refuse the consumed container shell and load the next one into the chamber. This had to be done for every shot fired, and was cumbersome and took time. The machine gun is designed to shoot continuously hundreds of ammunitions per minute. The outcome it had been was to execute a lot of soldiers and far more than ever could be killed by soldiers equipped with rifles. An additional thing that help making the machine gun so effective was with the way the soldiers were trained to bring attack on the target. All of them would run toward the waves. This was in effect means when the adversary was only armed with rifles where you had to aim to shoot the enemy. But, when an army of running men encountered machine guns they were trimmed down effortlessly. These particular firepower might even have even played a part of bringing the war to an end. Telephone: The aim of the harmonic telegraph is to perceptibly connect with people who are without reach straightaway. Before the telephone, long distance messages were through telegraph machines that were less efficient and took longer to get messages across because only dots and dashes at...
