E. READING
I. Read the passage and choose the best answer.
Hardware and software are two terms you’ve probably heard of at some point or another. The odds 
are high that you use both on a daily basis, whether it’s with your smartphone or personal computer. 
Let’s take a deeper look at what these two things are and why they’re important.
Hardware is any element of a computer that is physical. This includes things like monitors, keyboards, 
and also the insides of devices, like microchips and hard drives. Software is anything that tells 
hardware what to do and how to do it, including computer programs and apps on your phone. Video 
games, photo editors, and web browsers are just a few examples.
Hardware and software are different from each other, but they also need one another in order to 
function. The hardware would be the physical phone itself, and the software would be its operating 
system and apps. If we were to take away the software, we would just have a dead phone in our 
hands. It wouldn’t be able to make calls, text, or go online because it’s not receiving any instructions.
On the other hand, let’s say we have no hardware, meaning there’s no actual phone. If all we have are 
the programs, we just have a bunch of instructions but nothing to give these instructions to. 
Hardware needs software to tell it what to do, but software also needs hardware in order to act out 
its directions. When you combine the two, you can do all sorts of things, whether you’re using a 
smartphone, computer, or any other type of device.
Technology will continue to evolve. We may not be sure how it will look in 100 years, but hardware 
and software will be there serving as its foundation.
