DIFFERENCE BEETWEN RAM AND ROM

 

What is RAM

    The data required by the CPU to operate the operating system, software applications, and processes is stored in RAM (Random Access Memory). RAM operates at a rate measured in nanoseconds. The fast speed of RAM allows for speedy switching between several tasks.

    A computer's RAM capacity, which is delivered by RAM chips, typically varies from 64MB to 4GB. You could think about updating your RAM chips if you wish to add extra RAM.

What is ROM

    Instructions needed for bootstrapping or computer starting are permanently stored in ROM (Read Only Memory). It functions by keeping the BIOS and other hardware firmware. It seldom requires upgrading and is quite hardware-specific. Even when the PC is shut off, data contained in ROM is retained. Due to this functionality, you won't lose your data.

Difference beetwen RAM and ROM

    Now that you are familiar with two types of memory, you should concentrate on ROM vs. RAM. The four primary characteristics of ROM vs. RAM memory differences will be discussed (storage capacity, physical appearance, data retention and speed).

Storage Capacity

    A ROM chip on a computer typically has a storage capacity of 4MB, which is less than a RAM chip. Gigabytes of data may be stored on a RAM chip. How many gigabytes are there in a megabyte? You will understand the RAM and ROM memory's respective storage capacities after reading this text.

Physical apperance

    The motherboard has a slot for the RAM, a small rectangular chip, and a magnetic tape-based optical drive for the ROM. Furthermore, RAM often has a larger size than ROM.

Data retention

    The two memories clearly differ in terms of data retention. ROM is a type of non-volatile memory, meaning that the information will be retained even if the computer is turned off. On the other hand, RAM is thought of as a volatile memory that only stores data when the device is operating. Therefore, if the computer crashes or is switched off, you will lose your data.

Speed

    Here, speed is broken down into two categories: writing data and accessing data. The two speeds are both significant. ROM cannot access data as quickly as RAM. It signifies that RAM accesses computer data more quickly than ROM does.

Additionally, it helps accelerate your PC's processing performance. While RAM reads data at a few MB/second, ROM reads data at a few GB/second.

When it comes to writing data, RAM is simpler than ROM to do so. This is so that the relatively limited, but extremely significant and durable information, may be stored in the ROM. Data can seldom be changed in the majority of ROM memory formats (EEPROM is an exception).
