【Differences between RAM vs ROM Memory】Types and Examples ▷ 2022

Know the differences between RAM and ROM It is something that many users who know a little about equipment want to know. This is due to the fact that, despite the fact that the first is mentioned more and, in general, its use is usually clearly expressed, the second is the great forgotten of memories, constantly being confused with one and the other.

ROM memoryas we say, is often confused not only with due to the similarity of the acronym , but also with the hard disk due, among other things, to the fact that, like this, the information it contains is permanent.

Be that as it may, this is the text that will allow you to know what is RAM, what is ROM, what are they used for and how are they different?.

What is RAM and what is it for? types and examples

RAM literally means Random Access Memorytranslated as random access memory. It is a memory that is included in the devices to facilitate the continuous work that is carried out in these. What it does is store part of the information of the procedures that are executed during a period of time by software that we have installed, whatever type they are.

Thus, we have the information that will be stored is totally temporary, given by the tasks what we are doing at all times. It changes continuously, writing and deleting itself. all the time and in any position.

In addition, when the system in which it is located stops receiving energy, it fades; it will not be kept when we start the equipment working again, everything that was running will have finished and, with it, the temporary information that was in the RAM.

We can also indicate that It also serves to free the hard drive from so much worksince the use of this information is constant, which would require that, if the information was found in the storage unit, it would have to be really fast to work with it, RAM is. The existing types of RAM are SRAM and DRAM and their corresponding subtypes (NVRAM, MRA, SDRAM, ADRAM…)

What is ROM memory and what is it for? types and examples

ROMs it means Read-Only Memorywhich comes to be, in Spanish, memory of only reading. The ROM is a data and software digest that is read as soon as a system is started to make it bootable, both by instructions and by checking data. This is the first and only unit read at this point; that is why this information is not found on the hard drive (in fact, part of that information is needed for it to be detected and, therefore, work).

Logically, this information cannot be temporary. It is a set of information that is completely necessary, specific to the system in question, so it has to be maintained.

From this we also have that, even if we run out of power supply, this will be maintained forever, being available to enable starting at any time. It is unalterablehence the name read-only memory. It can only be modified by the manufacturer. The types of ROM that we find are ROM, PROM, EPROM and EEPROM and its subtypes.

Main differences between the functions of computer RAM and ROM memory

From both definitions you will have been able to deduce that, despite being two memory units, they are nothing more similar to each other, in addition to being part, of course, of the same equipment.

Let’s see what is different in all aspects, with special attention to the functions they have for our computer equipment:

• Use: We have already verified that the two memories are used for very different things. The RAM temporarily stores data about secondary software tasks that are being carried out during the use of the equipment. The ROM is a memory that includes the minimum data necessary for the system of which it is a part to function.
• Continent: Memories are software, that is, logical components. Even so, they rest on physical continents. RAM is stored in elongated modules with pins; currently these are worked on aesthetics, being a claim for gamers. The ROM is much smaller in size and its design is reduced to the purely functional, without any additions.
• Alterability: RAM memory is easily alterable. In fact, it automatically stores and deletes information based on the tasks that are executed; that is its task. It is not changeable by the user, it is a compendium of information necessary to start the system, so it must remain, by obligation, unalterable.
• Volatility: The difference is clear between RAM and ROM in this case; RAM is completely volatile, once it stops working all the information it had is lost. The ROM, due to its logical function, remains identical forever, being available at any boot.
