What is a protocol? "A well-known set of rules and standards used to communicate between machines."  The internet must follow a protocol so that all machines using it can effectively communicate. What is an Internet Protocol (IP) address? An IP address is a number unique to each device on a network. It works a lot like a mailing address, where a device finds another address and also sends its return address so the two devices can communicate. How is it organized hierarchically? The first numbers identify the country and regional network of the device, then the subnetworks, then the address of the specific device. How many bits are in an IPv4 address? 32 How many IPv4 addresses does that mean there are?   2^32 What is the difference between IPv6 and IPv4.   IPv6 has 128 bits, IPv4 has 32 bits. Why do we need IPv6? IPv4 does not have enough possible addresses for all the devices in the world, so we have to add more bits. What ...

In the world of computers, which is rapidly encompassing the entire world, perfection is becoming the new norm. People expect that when they send a message, it will be delivered exactly as intended. When they send a photo, the photo received will be identical to the one sent. Human error is expected. A typo in an essay is normal. A wrong turn is normal. But even these human errors are being corrected by computers. Autocorrect counters human error in messages and a GPS flawlessly directs a driver to an intended destination. As the trend toward increased computer usage continues, so too will the trend toward perfection, and it will become normal. As a student, the perfection of computers allows a highly efficient and reliable transfer of data between teachers and students. Teachers can print out documents for students to read, knowing that all students are receiving the same information. Students can submit assignments without ever seeing the teacher. I'm currently in a VHS class...

The main circuit board in a computer. This question almost got me because I don't know the difference between a CPU and a motherboard.  When the number of bits is not large enough to hold the number - what happens? I genuinely just didn't know that answer to this so I guessed wrong. I now know the higher order bits will be lost, so only the ending digits will be counted. What is missing from this code? I got this right, but at first I thought the "+ x" was changing the value of x. I knew that it wasn't changing the value of x because it was in the println statement and not it's own statement. What will print in this code? I got this wrong because I added 15 to 16 for when i=3, not realizing that the code will not run when i=3. The answer should be 16 (1+5+10). Which of the following only requires a single bit of storage to represent the data? I answered this correctly, but I can see how it would be confusing. The temperature and a grade on a mat...
