Some easy computer units conversion&Q’s???
Can anyone solve these problems with specific steps for me??? thanks~!!!
1.)If a picture was made up of 64 possible colors, how many bits would be needed to store each pixel of the picture???
2.) How many bits are there in 12 KB?
3.) Multiple Choice: Which of the following is equivalent to 2^20 X 2^2 bits? (2KB,4KB, 2MB, 4MB, 4GB???)
4.) Multiple Choice: How many different items can be represented with 11 bits? (11,22,121,1100,or 2048?)
5.) Multiple Choice: Which of the following is an example of an analog device? (mercury thermometer, computer, music CD, digital alarm clock, or vending machine?)
6.) Multiple Choice: Which of the following is NOT a valid Java identifier? (Factorial, anExtremelyLongIdentifierIfYouAskMe. 2ndLevel, level2, highest$ ???)
7.) Multiple Choice: Which of the following is a valid Java identifier? ( 14andCounting, max_value, 123, %taxRate, hock&ladder ???)
1. 2^6 so 6 bits, but that is somewhat weird unit to actually implemented.
2. 12 kilo = 2^10 * 12 = 1024 * 12 = ?
3. 2^20 * 4 = 2^10 * 2^10 * 4 = 4 mega
4. 2^11 = 2048
5. mercury thermo
6. 2ndLevel
7. max_value
