In the following guide we will tell you a little about What is the difference between RAM and ROM and what types are there? So that you eliminate all the doubts that arise in relation to these two types of memory.
Today’s is a comparison between RAM and ROM. If you want to learn much more, it is recommended that you read what RAM is and what it is for , which is essential for computer performance. Let’s continue with the differences between ROM and RAM.
What is the difference between RAM and ROM and what types are there?
There are multiple components that integrate our computers and other technological devices, some of these create great debate and doubts, such as RAM and ROM memory .
RAM and ROM memory are often confused with each other, but the truth is that they are very different and each one fulfills fundamental roles in multiple technological devices, as is the case with computers.
The first thing you should understand is that both, although they are two types of memory, work very differently, something that you can learn if you read the following information that we have prepared for you.
RAM
RAM memory plays a fundamental role in the performance of our computers, its name comes from Random Access Memory , which would translate to random access memory, something very akin to its operation, as we will see below.
A simple way to explain how RAM memory works is by indicating it as that type of memory that is stored by the software used in our computer. The default programs of the operating system, applications, games and others consume RAM memory to function.
This type of memory is managed jointly by the CPU and the software that uses it, it is a type of memory that stores temporary data and stands out for its high operating speed, something especially useful to quickly access this information. In fact, it is possible to overclock RAM and make it run even faster, the above being some of the most notable differences from ROM.
Another characteristic aspect of RAM memory is that it is a type of volatile memory. Volatile means that the stored information is deleted when the power supply is cut, in other words, when the computer is turned off.
Finally, this type of memory is also characterized by the fact that it is possible to install or change your PC’s RAM memory modules without major complications, considering this element as essential for the computer’s performance.
Types
- SRAM: It is a type of static memory and faster than DRAM. Even so, its cost is very high, so it was not standardized.
- DRAM: This is the standard in our computers, it is made up of multiple chips that store information. It usually represents a balance between speed and convenience.
ROM memory
Everyone knows about RAM but on the other hand ROM is partially unknown to most users. In any case, this also has great relevance for the proper functioning of our computers. In fact, it is essential for its operation, just like RAM.
Surely you wonder what is ROM? First of all, you should know where its name comes from, ROM comes from Read Only Memory , which would be translated as ” Read Only Memory “. It is a type of memory characterized mainly by not being as fast as RAM memory, and it is not erased when the power is cut.
Although it has “read-only” in its name, the truth is that ROM memory has evolved over time. Given this, today there are many modules with reading and writing capabilities . Although, in most cases, the ROM does not have a large storage capacity.
One of the most important uses for ROM is in the BIOS. This system is stored inside a ROM memory module . In any case, this type of memory has also been present in other devices, such as mobile phones or video game consoles.
Types:
- MASK ROM: It is a type of unalterable memory created in the manufacture of devices.
- PROM: It is a programmable memory, after manufacturing, but then it cannot be changed.
- EPROM: It is programmable and can be erased but under special conditions.
- EEPROM: The most common mode, it can be programmed an unlimited number of times (with some conditions).
On the other hand, as you can imagine while it is possible to increase the RAM memory of your computer , the ROM memory is fixed in most circumstances. In fact, it is only present most of the time in components such as the BIOS, at least in computers.
