In this post, I will explain RAM and ROM - Advantages, Disadvantages, Characteristics, Features.

This Article is Best on the whole internet.

If you read this article carefully you will understand all about the computer memory RAM and ROM.

I Guaranteed you, after reading this article you will not need to read any other Articles. In fact, our reader’s satisfied with this blog post.

What is RAM and ROM Memory?

RAM and ROM is the main memory of the computer system. This memory plays an important role in running the computer system.

Without RAM and ROM memory, the computer will not be able to perform any basic instructions.

The computer system has to use these memory to complete any instruction. This memory is installed in the computer's motherboard in the form of physical memory.

What is RAM in Computer?

RAM ( Random Access Memory ) is a Primary memory of a computer. This memory store temporary data because this memory is the temporary memory of computer.

Temporary data means, As long as your computer system is running, your data is stored in RAM and as soon as your computer is shut down, the data stored in RAM gets deleted.

There will be a lot of software installed in your computer and as soon as you open any software, then that software is first loaded in RAM memory and after loading in RAM it is opened.

The operating system of your computer system is also first loaded into the RAM, after that your computer is turned on. There are various types of RAM Memory.

I hope you understand What is RAM in Computer.

What is ROM in Computer?

ROM ( Read Only Memory ) is also a Primary memory of a computer.

Read Only Memory means, that you can only read the data of the ROM and you cannot edit the data of the ROM. 

This memory store permanent data because this memory is the permanent memory of a computer. Permanent data means, Once the data is stored in the ROM, then that data is never deleted.

ROM's data is permanent because ROM is a non-volatile memory.

I hope you understand What is  RAM in Computer.

Advantages of RAM ( Random Access Memory )

There are many advantages of RAM is given below.

• RAM Faster than secondary storage.
• RAM can capably read and write any type of data.
• RAM consumes less power compared to hard disk, CD, DVD, FLOPPY disk.
• No part of RAM moves when RAM executes an instruction.
• RAM memory increases your computer speed.
• Central Processing Unit (CPU) reads any data faster because of RAM.

Disadvantages of RAM ( Random Access Memory )

There are many disadvantages of RAM, which is given below.

• RAM is an expensive memory. It means costly.
• RAM is slower than the CPU cache memory.
• RAM memory has limited space for storing data.
• RAM is volatile memory means, Stored data in RAM cannot permanent.

Features and Characteristics of RAM

• RAM memory is capable to do both operations like write and erase.
• Adding more RAM helps to boost up your computer system speed and working performance.
• RAM memory allows the CPU to access data faster so that the computer can complete an instruction quickly.
• RAM is less expensive than SSD, but in comparison to performance, RAM completes any instruction from SSD quickly.

Advantages of ROM ( Read Only Memory )

There are many advantages of ROM, which are given below.

• ROM is more reliable than RAM.
• Easy to test ROM Memory.
• ROM is a non-volatile memory.
• Stored data in ROM is Permanent.
• ROM data cannot be changed.
• ROM Memory is cheaper than RAM Memory.
• ROM is static memory so does not need to refresh every time.
• ROM Memory helps to boot the operating system ( OS ).

Disadvantages of ROM ( Read Only Memory )

There are many disadvantages of ROM, which are given below.

• ROM is a slower type of Memory.
• ROM Memory is capable of reading data only, cannot be changed the ROM data.
• Once the data is stored in the ROM, you cannot modify, delete or overwrite the data in the ROM.
• Unlike RAM, incorrectly erasing the ROM Memory contents will brick the memory.
• Some Special types of ROM Memory, allow the to user can only rewrite contents.

Characteristics and Features of ROM

There are many characteristics and features of ROM Memory, which are given below.

• ROM Memory consumes low power.
• ROM memory is not expensive than RAM.
• The simple interface of ROM compared to RAM.
• The testing method of ROM Memory is very simple.
• ROM is a non-volatile memory. Non-Volatile Means Permanent data that doesn't get deleted.
• The data of the ROM is not deleted even after the computer shuts down suddenly.
• ROM is a static nature memory that does not need to be refreshed frequently.
• ROM Memory is capable to store data for a long time permanently.
• ROM is a very reliable memory because all the circuits used in this computer memory are very simple.
• The data of ROM memory is always known, so the data in this memory can be easily verified.
• All kinds of necessary data are already stored in ROM memory, which is required to start our computer system and load the operating system.

Advantages & Disadvantages of PROM

Advantages and Disadvantages of Programmable Read-Only Memory ( PROM ) are given below.

Advantages & Disadvantages of EPROM

Advantages and Disadvantages of Erasable Programmable Read-Only Memory ( EPROM ) are given below.

Advantages & Disadvantages of EEPROM

Advantages and Disadvantages of Electrically Erasable Programmable Read-Only Memory ( EEPROM ) are given below.

FAQ Related to RAM and ROM

Which is better RAM OR ROM?

RAM and ROM both are better both computer memories are fine in their own place. Both memories have different functions that they perform.

Because both the memory is very important for our computer.

Why ROM is used in Computer?

Every component in our pc, every element of computer, and each memory has its own function. Similarly, the function of ROM is that gives instructions to the RAM to boot the operating system. To do this work ROM is used on the computer.

Can we add more RAM to Laptop?

Yes, you can add more RAM to the laptop. Basically, two slots are available on every laptop.
