RAM and ROM are used to store the data running in the operating system and both have a very similar given name in abbreviation. Without a study, people will think both are the same functions because they are named a kind of memory. In fact, the function of the role in the computer is totally different. RAM is the abbreviation of random access memory which is used to work with CPU for temporary memory to process and work in nanoseconds. On the other hand, ROM is the abbreviation of read-only memory which is used for permanent storage and is as same as the secondary storage to keep your data for a long time. In reality, except for the operating role in the computer, the biggest difference is the capacity. We can very easily see the capacity of ROM and secondary memory up to hundreds of GBs and go beyond TBs for secondary memory. However, the capacity of RAM is in the range of 4 and 64 MB. Although the capacity is much smaller in RAM, the speed and data access are much faster than ROM.

Mission-critical system is any IT component that plays a critical role in the business operations of an enterprise, and once a malfunction or disruption of this system happens, it will lead to a significant adverse impact on the business and might even affect the survival of the business. The ERP system is considered as a mission-critical system in our company, as it is considered as a central function which manages accounting, sales, production, etc. Once it is down, we lose the access to the management and also the data for business and therefore might affect our business process. Our ERP system also runs on a relational database management system that is hosted in the cloud, which stores critical data for business and performs advanced data analytics. If this data management and analytics system is down or the major cloud service is disrupted, our corporate portal will not be accessible since this data center servers all our applications, and it might result in critical business impact such as being unable to process orders, unable to make payments, etc. This all will lead to revenue loss.
