Computer Systems

What information does RAM hold?

• The information your computer is actively using so that it can be accessed quickly.

• The information that has been sent to the printer.

• The information your computer is not actively using so that it can be accessed quickly

• The information your computer is actively using so that it does not need to be accessed

What is the role of the CPU?

• The CPU is a circuit board and foundation of a computer that is the biggest board in a computer chassis.

• The CPU is a low-level software that supports a computer's basic functions, such as scheduling tasks and controlling peripherals.

• The CPU performs the basic arithmetical, logical, and input/output operations of a computer system

• The CPU is a high-level software that supports a computer's basic functions, such as scheduling tasks and controlling peripherals.

What is the motherboard of a computer?

• The low-level software that supports a computer's basic functions, such as scheduling tasks and controlling peripherals

• The CPU is the primary component of a computer that processes instructions

• The motherboard is a printed circuit board and foundation of a computer that is the biggest board in a computer chassis.

• The motherboard is a circuit located in the monitor.

Which of these is not an input device?

• Keyboard

• Monitor

• Touch screen

What is an operating system?

• the low-level hardware that supports a computer's basic functions, such as scheduling tasks and controlling peripherals.

• The low-level software that supports a computer's basic functions, such as scheduling tasks and controlling peripherals.

• The high-level software that supports a computer's basic functions, such as scheduling tasks and controlling peripherals.

• the middle-level software that supports a computer's basic functions, such as scheduling tasks and controlling peripherals.

What is an algorithm?

• The increase in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition.

• A process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.

• A process of breaking down a complex problem or system into smaller parts that are more manageable and easier to understand.

• The reduction in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition.

What is decomposition?

• A search algorithm that finds the position of a target value within a sorted array

• The process of breaking down a complex problem or system into smaller parts that are more manageable and easier to understand

• The process of combining complex problems or systems into larger parts that are more challenging.

• A simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order

What is a binary search?

• A sequentially checks each element of the list until a match is found or the whole list has been searched.

• A simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order

• A search algorithm that finds the position of a target value within a sorted array

• A method for finding an element within a list.

What best describe a linear search?

• A search algorithm that finds a specific value.

• A search algorithm that finds the position of a target value within a sorted array.

• A sequentially checks each element of the list until a match is found or the whole list has been searched.

• A simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

What best describes Bubble sort?

• A simple sorting algorithm that reads through the list and swaps them if they are in the right order.

• A complex sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order

• A simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order

• A simple sorting algorithm that reads through the list and swaps them if they are in the wrong order
