What is a Resource?

[Eamonn]

In general terms what is the meaning of the term resource?

Choose any 3 key resources within a computer system and describe the impact if the resource is limited. If applicable, describe how the operating system plays a role in sharing the given resource

[Sang]

A resource is a software or hardware which is accessible by computer.
Primary memory: the operating system will not be able to process instructions and processes will not be able to execute.
Persistent storage: can lead to a system failure
CPU: If it cannot process instructions quickly enough, there would be an experience of latency, lag, or failure. This would result in cascading failure, as one process may not be able to execute instructions, which may impact a different process.

Resources are all the hardware and software components that work together in a computer system.

Primary memory: If primary memory is limited then you will not be able to store any more files on your disk. It can lead to programs not being able to run as the computer can’t use it for virtual memory anymore. It will take longer for programs to load as it will take longer time for the computer to search for the files.
Screen resolution: If this screen resolution is too low then the user will not be able to get visual feedback from the computer system.
Bandwidth: If bandwidth is too low then information cannot be passed around the computer system fast enough, slowing it down.

The operating system mainly controls the allocation and use of a computer system’s resources among the various user and tasks.

Generally it means what a individual, or group has that can be used in some way to accomplish a goal or operate something.

1. RAM: If limited the computer will start using Virtual RAM which means computer will that application slower than the rest. The OS plays the role of allocating the resource and decreae the space a application take if the app isn’t used as much as others.
2. Storage: If limited the OS will start to clear up temporary files and files that haven’t been used by the user in a long time. Which can result in data loss. The OS plays the role of storing files. However also it must store the files in a lossless format to take less space and prevent data loss. Which is up to the OS to decide how to accomplish that.
3. CPU: If limited then visual response by the computer will stutter and lag behind the current state of the program/s being run. The OS role is to prioritize which applications need more CPU attention compared to other applications based on which programs are more used than others.And respond by allocating it accordingly.

In general terms what is the meaning of the term resource?
– something that can be used by a person or organization in order to function effectively.

Choose any 3 key resources within a computer system and describe the impact if the resource is limited. If applicable, describe how the operating system plays a role in sharing the given resource.

Processor
– if the processor is limited then the amount of task that the computer can execute is also limited. the stronger the processor the more tasks it is able to complete more tasks in a shorter amount of time. The operating system receives input from the user and provides tasks for the processor to complete. the processor then works with other components in the computer to complete the given task.

RAM
– If ram is limited then the computer is forced to send and store data on virtual memory which is a much slower process as secondary forms of memory is not as fast as ram. Thus this results in the programs running much slower. The operating system communicates with the CPU, which then the CPU communicates with the RAM and other components of memory all in order to complete a given task.

Hard Drive
– Hards drives are a non-volatile form of data in which if it is limited or up to its max capacity, the user may be unable to store anymore programs and files onto the computer. This limits the usability since any task that require data to be stored in the hard disk would be unable to execute. All files and programs are usually stored on the hard-disk including the operating system as well. The hard drive also communicates with the operating system through the CPU. The CPU sends data to the hard disk using it as a tools to complete tasks.

In general terms what is the meaning of the term resource?
– In general resource means all the materials/stuff available around us that can help us satisfy our needs and wants.

Choose any 3 key resources within a computer system and describe the impact if the resource is limited. If applicable, describe how the operating system plays a role in sharing the given resource
– Ram, if ram is limited, then the system will switch to virtual memory which is much slower. It also effects the amount of processes that can be done simultaneously.
– CPU, if cpu is limited, then the processor will take a longer time to carry out the tasks.
– Hard disk, if a hard disk is limited, there wouldn’t be enough storage to save work so it would limit the amount of things that can be saved.
