RAM vs ROM
Computer memory has a lot of different features and attributes to remember that can confuse many. There are a few different types of memory that reside within your PC, different names for each, different purposes, variations, and much more.
Both RAM and ROM are two very different types of memory present in every PC. They have different purposes and actions to perform. In addition, both function in different ways and have many different features, making them both equally necessary for the proper function of any computer.
What’s the Difference Between Ram and Rom?
Here is all you need to know about the RAM vs ROM difference. This includes how both work, what they’re made of, and what makes each unique.
RAM stands for Random Access Memory. This is a PC component that sits on the motherboard in designated slots in the form of slim rectangle cards. They’re known as RAM sticks and differ in performance stats but not in size or shape regarding the actual slot.
RAM is classified as a volatile type of memory. This means that it’s not permanent, and is lost every single time the computer is shut down or restarted. That’s completely normal, as this type of memory isn’t designed to store permanent data like images, documents, or anything similar on your PC.
The main purpose of RAM is to store important pieces of data for various applications in order to reduce access time significantly. This allows each app on your device to load faster and provides the ability to load and run multiple apps simultaneously. It’s a very important component that has a part to play in determining the speed and performance of any PC. In addition, overclocking the RAM can boost speed given that the CPU can handle it.
If you ask yourself how much RAM your PC needs, the more the merrier is usually the answer. However, it has to match with other components like the CPU and motherboard to prevent you from going overboard.
Read-Only Memory, aka ROM, has a few significant differences compared to RAM. The main difference is that it is the opposite type of memory, a non-volatile one. This means that the data that gets written on this type of memory is there to stay, permanently.
As opposed to RAM, where data is stored as electricity and needs power not to be deleted, the memory in ROM is stored and written to each cell using binary code. This allows it to stay there even after there’s no more power to the computer. So even when you shut down the PC, everything that was stored on the ROM will still be waiting there when you turn it back on again.
ROM is also much slower when you compare it with RAM and features less storage capacity. The main way ROM is used in PCs is for the start-up process or bootstrapping, whereas RAM is used continuously while the computer is active. While ROM doesn’t affect your PC too much after start-up, RAM speed can have great effects on performance. This is why most users focus on getting gaming RAM.
Main Differences Between RAM vs ROM
Even though they are very different parts of the computer, both RAM and ROM deal with various types of memory and are crucial for a normally working PC. Here are the main differences that you need to remember when it comes to ROM vs RAM.
- It’s significantly faster to write data on RAM than it is on ROM
- RAM is volatile, whereas ROM is permanent
- RAM only holds power while there’s power. ROM can keep all the data even when power has been cut off and the PC is shut down
- ROM stores less data and has less storage capacity than RAM
- The main uses for RAM are in CPU cache and primary memory. The main uses for ROM are firmware and micro-controllers
Is It Possible to Use Flash Drives as RAM?
Finding ourselves at a loss of memory can be difficult when we’re performing an important task. If your system runs out of memory, some programs might crash and more often than not, the ones that do crash are the ones that you are using for work. Sometimes, video games cause crashes through memory leaks or […]
How to Confirm Your Interrupt-Affinity Policy Tool Settings
Setting up your affinities is quite a popular optimization process that can help you reduce your DPC latency and improve the performance of your GPU or the stability of your USB devices. A big issue that I have noticed though is that people do not test if the Interrupt Affinity Policy Tool setting has been […]
This Is Why You Should Use More Thermal Paste for Your CPU!
It is pretty clear that having too little thermal paste is a lot worse than having way more than needed for your GPU, but what about your CPU? The traditional approach to this always stated that a small rice grain size dot of thermal paste is more than enough for your CPU to have proper […]
This Is Why You Should Use More Thermal Paste for Your GPU!
Your GPU temperatures are dependent on your heatsink plus fans combo and the thermal paste that acts as a bridge between the die and the heatsink. Having dead fans, or a bad/old thermal paste application in most cases equals a very hot graphics card causing issues for your PC. An important question when dealing with […]
How to Replace Dead GPU Fans
Your graphics card is one of the components that works the hardest in your PC when you are gaming or completing tasks that can be GPU accelerated that is why it is important to keep it cool at all times. While not common, dead fans (grinding fans, slower RPM, uneven rotation, etc) on a GPU […]
Fan Control – One Software for All Your Fans
Keeping your CPU and GPU cool is the most basic way in which you can increase the performance of your PC. A bunch of fans in your PC case is the fastest and cheapest way to maintain proper thermals but for many users taking care of all those fans is a bit confusing. Some people […]
