Computer Science Exam Trivia Quiz!

The CPU or central processing unit is the point where all data from the computer system is calculated and processed.

RAM or random access memory is where information from the hard drive is stored on to the RAM so the processor can access it much faster.

operating system, e.g. Windows, Apple, Linux.

The given binary number is 10001111. To convert this binary number to denary, we start from the rightmost digit and multiply each digit by 2 raised to the power of its position. Adding all the results, we get the denary number 143.

A byte is a unit of digital information that consists of 8 bits. Each bit represents a binary value of either 0 or 1. Therefore, there are 8 bits in a byte.

ROM or read only memory stores and saves information.

The register is a small, high-speed storage area within the processor that holds data and instructions that the processor is currently using. It allows for quick access and retrieval of data, which helps in improving the overall performance of the processor. Therefore, the statement that the register stores data that the processor is using is true.

Cache is a small block of fast memory stored in the CPU or in-between the CPU and memory. It can be accessed much faster than the main memory. If the cache was removed, the computer would run at 10% of its current speed. Therefore, the correct answer is cache.

Assembly code is indeed a low-level language. It is a type of programming language that is closely related to machine code and is specific to a particular computer architecture. Assembly code uses mnemonic instructions that directly correspond to the machine code instructions of the computer's processor. It is considered low-level because it provides a close representation of the hardware and allows for direct manipulation of the computer's resources, such as registers and memory. This makes assembly code more efficient and faster than high-level languages, but also more complex and harder to write and understand.

the clock speed is measured in GHz.

RAW images are uncompressed images. Each pixel has its own colour value

a byte is 8 bits (11111111 is the biggest number in binary which in denary is 255)

No - this is just the mark up language for a web page - not a program in itself

Operating systems perform several essential functions, including creating a file system, managing security through usernames and passwords, and transferring programs into and out of memory. Creating a file system involves organizing and managing files on a storage device. Managing security through usernames and passwords ensures that only authorized users can access the system and its resources. Transferring programs into and out of memory involves loading programs from storage into memory for execution and saving them back to storage when they are no longer needed. These functions are fundamental to the operation and management of an operating system.

The correct components of a CPU are the Arithmetic and Logic Unit (ALU), Control Unit, Internal Buses, and Logic Gates. The ALU performs mathematical operations and logical comparisons, while the Control Unit coordinates and controls the flow of data within the CPU. Internal Buses are responsible for transferring data between different components of the CPU. Logic Gates are electronic circuits that perform basic logical operations. These components work together to execute instructions and perform calculations in a CPU.
