OS is an electronic device that can receive data (input), process it according to a set of instructions (called a program), and produce output. It can also store the output for future use.
True
False
Software is the set of instructions that tells the hardware what to do.
True
False
The operating system acts as an intermediary between hardware and user applications, managing resources and operations.
True
False
Every time you run an application, perform a calculation, or execute a command, the CPU is responsible for interpreting and carrying out the instructions.
True
False
Cache stores frequently used data and instructions so the CPU can access them quickly without waiting on slower main memory (RAM).
True
False
Motherboard allows the CPU, memory, storage devices, graphics card, and other components to communicate with each other.
True
False
Buses are data pathways that carry signals and data between the CPU, memory, and peripherals.
True
False
The chipset is a collection of chips on the motherboard that manage data flow between the CPU, memory, and peripherals
True
False
Southbridge (now mostly integrated into the CPU): Connects CPU to high-speed devices like RAM and graphics.
True
False
Northbridge handles lower-speed peripherals like USB ports, audio, and networking.
True
False
Which of the following components is often referred to as the ‘brain’ of the computer and is responsible for executing instructions and performing calculations?
Motherboard
Hard Disk Drive
Central Processing Unit
Random Access Memory
How does Random Access Memory (RAM) differ from a Hard Disk Drive (HDD) in terms of functions?
An HDD is volatile and loses data without power, while RAM is non-volatile.
RAM is used for long-term data storage, while an HDD is for temporary data.
An HDD runs all active programs, while RAM is used only for booting the system.
RAM provides temporary workspace for the CPU, while an HDD stores data permanently.
A graphic designer is experiencing slow performance and frequent crashes while working on a large project with many layers. What is the most likely solution to this problem?
Adding more RAM
Upgrading the monitor
Installing a larger Hard Disk Drive
Replacing the keyboard and mouse
A technician is troubleshooting a computer that power on but does not display anything on the monitor. They hear a series of beep from the motherboard. Which components is the most likely source of the problem?
The CPU, because it is unable to send signals to the display.
The power supply unit, as it is failing to deliver enough power.
The hard drive, as it is preventing the operating system from loading.
The motherboard, as the beeps indicate a failure with a connected component.
A user wants to build a new computer for gaming and video editing. They must choose between a Solid State Drive (SSD) and a Hard Disk Drive (HDD) for the primary boot drive. Which device would be the superior choice, and why?
HDD, as its larger storage capacity is better for storing large game files.
SSD, because it is cheaper to manufacture and therefore more budget-friendly.
HDD, because its mechanical nature makes it more reliable for long-term data storage.
SSD, because its lack of moving parts allows for significantly faster boot and load times.
What is the primary function of a motherboard in a computer system?
To display visual information on the monitor.
To store all the computer's programs and user files.
To convert AC power from the wall into DC power for components.
o serve as a communication hub connecting all the internal components.
If a computer's CPU has a clock speed of 3.8 GHz, what does this value primarily indicate?
The physical size of the CPU chip.
The type of socket the CPU will fit into
The amount of data the CPU can store temporarily.
The number of instructions the CPU can process per second.
You are installing a new CPU. After placing it into the socket, you must apply thermal paste and install a heat sink. What is the purpose of this action?
To protect the CPU from dust and debris.
To connect the CPU to the memory modules.
To secure the CPU firmly to the motherboard.
To prevent the CPU from overheating and causing damage.
Which of the following scenarios would most benefit from an upgrade to the amount of RAM, rather than the CPU?
A computer takes a very long time to save large files to the storage drive.
computer is struggling to run a modern video game at a high frame rate.
A computer's operating system takes a long time to boot up when first turned on.
A computer becomes sluggish when multiple programs and browser tabs are open simultaneously.
When building a new computer, a user is choosing between a cheaper motherboard with fewer features and a more expensive one with a better chipset. Why might investing in the more expensive motherboard be a better long-term decision?
It reduces the amount of electricity the entire system will consume.
It ensures the computer will never need to be upgraded in the future.
It automatically increases the speed of all other components connected to it.
It provides a more stable foundation and better support for high-end components like faster CPUs and RAM.
ANSWER THE QUESTIONS TO THE BEST OF YOUR KNOWLEDGE. (30 POINTS)
Explain the symbiotic relationship between a CPU and a motherboard. Why is it impossible for a CPU to function without a motherboard, and what are the specific roles each component plays in executing a simple task, such as opening a web browser?
Describe the differences in function and performance between computer storage (like a Hard Disk Drive or Solid State Drive) and computer memory (RAM). How do these two components work together to ensure a program runs efficiently, and what happens when a computer has insufficient memory to perform a task?
Elaborate on the role of an Operating System (OS) as an intermediary between the user, software, and hardware. Provide examples of key functions the OS performs to manage the computer's resources and to allow applications to run successfully. What would a computer be like without an OS?
