As we learned in this lesson, a byte is about the same amount of memory as a character, such as the letter 't'. There are approximately 7 million characters in all of the Harry Potter novels combined. How many bytes of memory would all of the Harry Potter novels take up? How many copies of the Harry Potter novels would fit on a 7 Gigabyte flash drive. (Remember 1 Gigabyte is 1 billion bytes.)

Give an example of a special purpose computer that you are familiar with and briefly describe its hardware and its software.

One example of a special purpose computer is a microwave because the programs on a microwave (like the "Popcorn" program) can't be changed. The hardware of a microwave include its buttons, the door, the light bulb, the transformer, the waveguide, the magnetron, and the control circuit. The software of a microwave is all of the programs that make the microwave run. These include the "Popcorn" program that is supposed to perfectly make your popcorn, the "Sensor" program that senses for a certain type of food/drink and adjusts the temperature accordingly, or a "Defrost" program which can be used to defrost meat.

   2. Explain in your own words the difference between running your app by "Connecting to the Companion" and running your app by "Packaging" it.

When running the app by "Connecting to the Companion", the MIT companion app transfers the software (blocks) to the phone and then interprets them for the Android operating system. The Android OS takes the software and interprets it for the phone's processor so the app can run. Because of the way "Connecting to the Companion" works, the code can be re-interpreted every time a change is made. This process is known as interpretation because the code is constantly being re-interpreted.

When running the app by "Packaging" it, a program changes the software (blocks) on the computer into binary code and then packages it in an .apk file. Using a barcode scanner or another piece of software, the .apk file can be loaded onto the phone so the Android OS can interpret the code for the phone's processor. This process is called compilation since all of the source code is changed into binary.

     3. As we learned in this lesson, a byte is about the same amount of memory as a character, such as the letter 't'. There are approximately 7 million characters in all of the Harry Potter novels combined. How many bytes of memory would all of the Harry Potter novels take up? How many copies of the Harry Potter novels would fit on a 7 Gigabyte flash drive. (Remember 1 Gigabyte is 1 billion bytes.)

The Harry Potter novels would take up approximately 7 million bytes. This means that 1,000 copies of the Harry Potter novels could fit on a 7 Gigabyte flash drive!

answerpixels;

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
