Quiz for Fundamentals of Programming

  1. Go emphasizes ease of programming. If you use the short declaration operator, you do not need to specify the type.
  • true
  • false
  1. In your own words, explain how computers work.

a.) Computers run on electricity. Electricity has 2 discrete states: on and off. With those 2 discrete states, we can create a coding scheme for whether or not a switch or circuit is in an on or off state.

  1. In relation to computers, what do zeros & ones represent?

a.) Ones and zeros represent an abbreviation of whether something is on or off. 1 is on, 0 is off.

  1. A boolean value is one that is either true or false.
  • true
  • false
  1. If you have 5 porch lights, how many messages can you encode?
  • 8
  • 16
  • 32
  • 64
  • 128
  1. The computer power symbol is cleverly a ZERO and a ONE. This is pretty neat as ZERO represents OFF and ONE represents ON, which is exactly what a power symbol allows you to do - turn something ON and OFF.
  • true
  • false
  1. "Bit" is an abbreviation of "binary digit"
  • true
  • false
  1. ON & OFF, 1 & 0, Binary Digits, Bits, and Machine Language are all words used to refer to this idea that, within a computer, it's all nothing but a bunch of ZERO's and ONE's, or switches that are ON or OFF, it's all just a bunch of Binary Digits, or Bits, that's the language which computers speak, it's machine language.
  • true
  • false
  1. circuits, switches, transistors, and even "gates" are all words used to refer to this thing within a computer that can either be ON or OFF. It's a circuit, it's a switch, it's a gate that can either be OPENED or CLOSED, it's a transistor - you will learn that people use all of those words to talk about this same thing, this ability of computers to store ON / OFF states.
  • true
  • false
  1. The world's most popular text coding scheme today is
  • ASCII
  • UTF-8
  • JIS
  • W Europe
  1. 1000 bytes =
  • 1 TB
  • 1 GB
  • 1 MB
  • 1 KB
  1. 1000 GB =
  • 1 TB
  • 1 GB
  • 1 MB
  • 1 KB
  1. Consult this link transistor count and then enter the number of transistors (aka circuits, switches) which can be found on processors today.

7 billion

  1. How many circuits (aka transistors, switches) did the Eniac computer have?
  • 160
  • 1,600
  • 16,000
  • 160,000,000
  1. rune is an alias for int32
  • true
  • false
  1. byte is an alias for uint8
  • true
  • false
  1. If you use type int, then the compiler will choose whether int32 or int64 is used. Another way to say this is that int has implementation-specific sizes.
  • true
  • false
  1. As a rule of thumb, for numeric types, you should just use "int" for whole numbers (without decimals) and "float64" for real numbers (with decimals)
  • true
  • false
  1. A string is a sequence of bytes, which is also known as a "slice of bytes"
  • true
  • false
  1. Go source code is always UTF-8.
  • true
  • false
  1. A string is a sequence of bytes that represent Unicode code points, called runes.
  • true
  • false
  1. What is a coding scheme?

a.) A series 0s and 1s which represents switches being on or off.

  1. What is the number 42 in decimal?
  • 42
  • 101010
  • 2A
  • I skipped the numeral system video
  1. What is the number 42 in binary?
  • 42
  • 101010
  • 2A
  • I skipped the numeral system video
  1. What is the number 42 in hex?
  • 42
  • 101010
  • 2A
  • I skipped the numeral system video
