Active and Passive Sentences (How Do Computers Work?) [RED ARMY]

From the article “How Do Computers Work?” we finally found some of the active and passive sentences after we read it, hopefully these sentences we found are correct. Here are those active and passive sentences that our group found : 

Active 

1.       Back in the 1940s, Thomas Watson, boss of the giant IBM corporation, reputedly forecast that the world would need no more than ‘about five computers’.

2.       She piles them[math problems] up on her desk until she gets around to looking at them.

3.       Each afternoon, she takes a letter off the top of the pile, studies the problem, works out the solution, and scribbles the answer on the back.

4.       The beauty of a computer is that it can run a word-processing program one minute and then a photo-editing program five seconds later

5.       The hardware is what makes your computer powerful; the ability to run different software is what makes it flexible.

6.       Today, most computer users buy, download, or share programs like Microsoft Word and Excel.

7.       That's the basic idea behind an operating system: it's the core software in a computer that (essentially) controls the basic chores of input, output, storage, and processing.

Passive

1.       Programs written for one machine (such as an Apple) usually wouldn't run on any other machine (such as an IBM) without quite extensive conversion.

2.       Suppose you're looking at a digital photo you just taken in a paint or photo-editing program and you decide you want a mirror image of it (in other words, flip it from left to right).

3.       In the 1940s, they were giant scientific and military behemoths commissioned by the government at a cost of millions of dollars apiece; today, most computers are not even recognizable as such: they are embedded in everything from microwave ovens to cellphones and digital radios.

4.       You probably know that the photo is made up of millions of individual pixels (colored squares) arranged in a grid pattern.

5.       Unlike the operating system, which is the same from one computer to another, the BIOS does vary from machine to machine according to the precise hardware configuration and is usually written by the hardware manufacturer.

6.       The BIOS is not, strictly speaking, software: it's a program semi-permanently stored into one of the computer's main chips, so it's known as firmware (it is usually designed so it can be updated occasionally, however).

7.       Everything a computer does, from helping you to edit a photograph you've taken with a digital camera to displaying a web page, involves manipulating numbers in one way or another.
