computer sub systems

A sub-system is a smaller part of a computer system that works together with other sub-systems to create a fully functional computer system.

The five main sub-systems in computers are: Central Processing Unit (CPU), Memory, Storage, Input devices, and Output devices.

The CPU sub-system executes instructions.

RAM is memory that stores data and instructions temporarily for the CPU.

True. Storage sub-systems store data and software permanently.

Input devices allow a user to enter information into the computer.

ALU stands for Arithmetic Logic Unit, which is a component of the CPU sub-system.

Two examples of output devices are monitors and printers.

One advantage of using sub-systems is that it allows for troubleshooting problems by isolating the sub-system that could be causing the issue.

HDD stands for Hard Disk Drive, which is a type of storage sub-system that stores data and software permanently.

Decomposition is the process of breaking down a large problem into a set of smaller problems.

The four key areas to consider when decomposing a problem are: inputs, processes, outputs, and storage.

True. Smaller problems resulting from decomposition can be tested independently.

In problem decomposition, inputs refer to data entered into the system.

Decomposition benefits game development by breaking down the complexity of the problem into more manageable 'chunks', such as levels, characters, and landscape.

Processes are subroutines and algorithms that turn inputs and stored data into outputs.

In a simple area calculation program, storage refers to width, height, and area stored temporarily in memory.

False. ** Decomposition makes solving large problems easier and more efficient** by breaking them down into smaller, more manageable problems.

Outputs are data that is produced by the system, such as information on a screen or printed information.

Decomposition helps with testing in software development by allowing smaller problems to be tested independently before being combined into the full solution.
