A programming language that supports relational databases is SQL (Structured Query Language)
Structured Query Language (SQL), is the principal method for communicating with Relational Databases.
A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.
Tables are utilized for storing data about the items that will be displayed in the database. A column in a database contains a specific type of data, whereas a field records the actual value of an attribute. The table's rows indicate a collection of linked values for a single item or entity.Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.

(b) When a computer systems RAM becomes full it can use virtual memory.
Explain what happens if the computer does not have any virtual memory.
Answer:
it won't be able to run
Explanation:
because computer runs on physical memory
If a computer does not have any virtual memory, the consequences of running out of physical RAM can be quite problematic.
When the RAM becomes full, the operating system relies on virtual memory as a way to supplement the physical memory shortage. Without virtual memory, the system would have no way to manage or accommodate the excess data that needs to be stored temporarily.
As a result, the computer would likely start experiencing severe slowdowns, freezing, or crashing when attempting to run applications that require more memory than is available.
In extreme cases, the system might even become unresponsive or display error messages indicating a lack of memory. Virtual memory acts as a safety net, allowing the computer to continue functioning by utilizing a portion of the hard drive as temporary memory storage when physical RAM is exhausted.
Without this essential feature, the computer's ability to multitask and handle memory-intensive tasks would be severely hindered.
