As soon as it’s ready, you open a file containing a document and start editing it using a word processor.If you take a snapshot of your system at that point, what will the processor (CPU) contain? Select 2 answers. All the instructions contained in the word processing program All the instructions contained in the operating system All the documents saved on your computer All the programs installed on your computer All the data for the document that you are editing The instruction that is currently being carried out Data for the instruction that is currently being carried out 12) You turn on your computer. As soon as it’s ready, you open a file containing a document and start editing it using a word processor.If you take a snapshot of your system at that point, what will the memory (RAM) contain? Select 3 answers. All the instructions contained in the word processing program All the instructions contained in the operating system All the documents saved on your computer All the programs installed on your computer All the data for the document that you are editing The instruction that is currently being carried out Data for the instruction that is currently being carried out 13) You turn on your computer.

Select 2 answers. All the instructions contained in the word processing program All the instructions contained in the operating system All the documents saved on your computer All the programs installed on your computer All the data for the document that you are editing The instruction that is currently being carried out Data for the instruction that is currently being carried out 14) What is the main task of a general-purpose computing system?. The main task is to execute programs. There is no main task. It can perform any task prescribed by a program. The main task depends on the system. Different systems may perform a different main task. The main task depends on the user. Different users may need the system to perform a different main task 15) Which of the following are logical operators?Note: There is more than one correct option. Select all that apply. + (addition) and (conjunction) or (disjunction) ⨉ (multiplication) > (comparison: greater than) not (negation or inversion) mod (remainder) 16) If X is a logical statement, what sort of values can it have? Any number Any sentence that makes sense Either true or false Either ‘yes’, ‘no’, or ‘don’t know’ 17) A laptop computer has a ‘Battery low’ indicator that starts flashing red when the battery power falls below 20%, but only if the laptop is not charging.Fill in the following table:Battery below 20%ChargingBattery low flashing redtruetruefalsetruefalsetruefalsetruefalsefalsefalsefalseWhich of the expressions below capture the behaviour of the ‘Battery low’ indicator? Battery below 20% < Charging Battery below 20% not Charging Battery below 20% or Charging Battery below 20% and not Charging Battery below 20% only if not Charging 18) Is the sentence below true or false?Complex components like the processor and the main memory can be created out of simple logic gates. True False 19) Are the sentences below true or false?Artificial intelligence is about creating machines that are more intelligent than humans. True False 20) Are the sentences below true or false?Creating a machine that can walk is not artificial intelligence because humans walk without thinking. True False 21) Are the sentences below true or false?With machine learning, machines are trained how to perform tasks by showing them examples or providing feedback True False 22) Are the sentences below true or false? Machine learning does not involve programming True False 23) Are the sentences below true or false?The performance of machines that are trained to perform a task is only as good as the examples that have been used to train them True False 24) What logic gate is this?first inputAsecond inputBAND outputA and Bfalsefalsefalsefalsetruefalsetruefalsefalsetruetruetrue AND gate OR gate Not gate XOR gate 25) How is the Antikythera mechanism similar to modern computers?Select 2 answers. The mechanism is purpose-built to perform a set of specific tasks. The mechanism receives input, the input is processed, and output is produced. The mechanism automates an information processing task. Its operation is hardwired and cannot be modified.
