Let’s say you open Chrome. The actual application is on the hard drive so that needs to be spinning and reading data. There also needs to be some RAM usage for the program to run. Same with graphics cards in games.
CPU usage is pretty much the biggest factor. If you run out of RAM, things just get super slow. However, if your CPU is going hard but still struggles, it can bottleneck things such as the GPU.
Resources are just what the computer needs to be able to perform whatever action you’re doing.
For example, if you have 1.0 GB (1024 MB) of RAM installed on your machine, then you have a total of 1024 MB of system resources. However, as soon as your computer boots up, it loads the operating system into the RAM. This means some of your computer's resources are always being used by the operating system. Other programs and utilities that are running on your machine also use your computer's memory. If your operating system uses 300 MB of RAM and your active programs are using 200 MB, then you would have 524 MB of "available system resources." To increase your available system resources, you can close active programs or increase your total system resources by adding more RAM.be a bit ambiguous. Just remember that while it usually refers to your computer's memory, it can be used to describe other hardware or software as well.
As you can see, the term "system resources" can be a bit ambiguous. Just remember that while it usually refers to your computer's memory, it can be used to describe other hardware or software as well.
when people talk about computer memory, it’s usually related to RAM Memory.
But in practical terms, we can think there’s only a main memory, since it would limit a lot your question scope. I’ll explain: if you have a RAM but you don’t have a ROM (which is a motherboard’s built-in memory), your PC doesn’t even turn on. Also, if you have a ROM but there’s no RAM, it will turn on but it’ll not boot. If you have both, but you don’t have a nonvolatile memory (such as a Hard Disk drive or any other device that takes on its role), PC will boot but Operating System will not start and you’ll get a useless machine.
So, under this point of view, we must have at least three main memories: ROM, RAM and a Disk (or an equivalent one) in order to make it useful.
Drawbacks
The drawbacks to HDDs are a result of the mechanical parts used to read and write data, as physically finding and retrieving data takes more time than electronically finding and retrieving data. The mechanical parts can skip or even fail if they are handled roughly or dropped. This is a concern in laptops, but not as much in desktops. HDDs are also heavier and use more energy than comparable SSDs.
Benefits of a HDD
The benefits of a hard disk drivs are that they are a proven technology, and are frequently less expensive than a solid state drives for the same amount of storage. Currently, HDDs are also available with more storage space than SSDs.
For a long time, it was this simple: the higher the clock speed, the faster the processor, and more cores meant better speeds. But processor technology today isn't dependent as much on the clock speed and cores because CPUs now have several other parts that determine how fast they can perform.
