It is false that Programmers can use SQL on systems ranging from PCs to mid-size servers.
Applications for structured query language can be found in a wide range of sectors, mostly in those that deal with database-related tasks. It might be used, for example, by a data analyst to query data sets and produce precise insights. On the other hand, a data scientist might use this programming language to add data to their models.
Businesses and other organizations use SQL tools to create and modify new tables as well as access and edit information and data in their databases.
A database is a tool for gathering and organizing data. Databases can store data about people, things, orders, and other things. Many databases begin in a spreadsheet or word processor. Many firms find it beneficial to move them to a database made by a database management system as they grow larger.
SQL helps manage the data kept in databases, enabling users to get the precise data they require when they need it.

Explanation:
The system environment includes all software external areas, which may vary from user to user. The System may be different, but it is part of the System environment, depending on the level of available memory. This environment is a part of the System development life cycle. and other options that are not correct which can be described as follows:
- In option a, Time and cost estimates are part of the SDLC. It is a part where we calculate the overall cost and time for making any new software.
- In option c, It is not a use in system environment it is reported.
- In option d, System Components are a hardware device that by system environment for making a system environment but it does not include systems security that's why it is not correct.
Answer:
The answer is "The variable is quantitative because it is numerically measured"
Explanation:
RAM is seen as a volatile memory, that doesn't have power the stored information is lost. But, whenever a CPU runs the RAM to store information needed for use very quickly and does not perpetually store certain information, the central processing system (CPU) uses RAM.
- RAM process the data into bytes, in which megabytes (MB) are its higher process value.
- All the value is countable in its numeric form, that's why the quantitative is the correct answer.
