Can you explain the distributive property please?
The distributive property is important because it combines both addition and multiplication. This property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. For example:
3(2 + 5) = 3 x 2 + 3 x 5
3(7) = 6 + 15
21 = 21
if we let a, b, and c be any whole numbers, then
a(b + c) = ab + ac

How many hex digits are typically used in computing?
Used for what???The hexadecimal system is just a way to represent information. Each byte requires two hexadecimal digits. Modern computers have billions of bytes in RAM, and often a trillion or more bytes on the hard disk, so that would be billions or trillions of hexadecimal digits.
Some examples of things that are often represented as hex digits:
* An IPv6 address has 16 bytes - so, 32 hex digits.
* A MAC address has 6 bytes (12 hex digits).
* A register has a few bytes. The size varies, but is often 2-8 bytes.

When was the height of the first computer?
The first commercial computers were punch card machines from Bull. Here you could stack punched cards on the second floor. IBM delivered these machines to Hitler so he could tally the Jews and round them up more effectively.
The IBM 360 and 370 had to be kept in special cool rooms, where air circulated in the floor and lead up to cool the computer, the disks and other peripherals such as printers and tape stations. In around 1985, the largest "mainframe" in the world held around 100GB of disk storage ' "DASD". It occupied a building, required huge cooling and carried a price tag of around $100 million.
The size of the first computers were limited by the human height - since wires had to be connected and stacks of cards was used to program them. Every bit of RAM memory was tiny iron cores that was magnetized. The enclosure for e.g. an Eniac, was typically about 8 x 6 feet and 6 feet tall - and operated from a "typewriter".
How do you save pictures from an iPhone to computer and then save the pictures to the computer?
If you took the pictures yourself, then you just need to attach your computer via USB and then in "My Computer" there will be a device called Apple Camera in which you will find your pictures.
If you found the picture using Safari, hold down on the picture and tell Safari that you want to save the picture and then follow the steps above starting with connecting your computer via USB.
If the pictures are from an app, refer to the apps instructional guide (if there is one) on how to save a picture.

What uses magnetic particles to store items on a disks surface?
Magnetic Disks, otherwise known as 'Floppy disks'.
The last generation of these disks were 3 1/2" and used a ridgid plastic case, to contain the magnetic disk within. Not very floppy.
The early versions were 7" and 5" and were contained in soft plastic outer sleeves. These were actually floppy.
there are 20GB in 20306MB.
To break it down for you, 1GB = 1024MB.
So roughly, people will commonly say, 1 thousand MB(mega byte) is 1 GB (Giga byte)
therefore 20,000MB is 20GB.
