Answer:
1) World War I popularized the use of the machine gun—capable of bringing down row after row of soldiers from a distance on the battlefield.
2) This weapon, along with barbed wire and mines, made movement across open land both difficult and dangerous. Thus trench warfare was born.
3) Warships became faster and more powerful than ever before and used newly invented radios to communicate effectively.
4) The British naval blockade of Germany, which was made possible by developments in naval technology, brought total war to civilians. The blockade caused a famine that finally brought about the collapse of Germany and its allies in late 1918. Starvation and malnutrition continued to take the lives of German adults and children for years after the war.
WWI was the first modern mechanized industrial war in which material resources and manufacturing capability were as consequential as the skill of the troops on the battlefield so technology was very helpful
