• Draw a simple Von Neuman machine and explain basically what each part does.
• Explain what the base of a number system means.
• create a table showing the first 16 numbers in Binary, Decimal, and Hexadecimal
• Why do we add a character to the end of numbers indicating the base of the system being used?
• Convert 242d to hexadecimal (hint, go to binary first, and make sure that d at the end does not confuse you!)
• Convert 0fch to decimal (hint, go to binary first. Again, note the h at the end, what does that indicate?)
• How does the computer decide if a memory container contains code or data?
• We said that memory holds two basic kinds of things in a computer. Actually, there are three things possible. What are they? (Hint: you normally throw the third one away!)
• If memory is organized as an array of bytes, how do we access other data types which need more space?
• What are the common names for the standard container sizes used in a 64-bit computer?
• How are negative integers represented in a computer?
• Show the binary encoding for +42 and -42 as eight-bit numbers, then show what you get when you add them?
• Extend both +42 and -42 to 16 bits.
• Basically, how are floating point numbers encoded?
