Answer:
Give at least one reason why it's useful to learn how to solve and program solutions with a limited set of commands. So that when there is more commands we know how to use the ones we have. parameters help generalize the solution to a specific problem. how are functions with parameters an example of abstraction?
Answer: Awnser below.
Explanation:
Basically, what you're going to need for a computer from my basic knowledge is a motherboard, of course, this is so you can actually use your computer. You'll need a PSU, or so called, a power supply. This will give power to your motherboard and the other components with it. You will need a CPU, this is basically the brains of the computer. This will run your operating system, and main componets. A GPU, this will give you a display for your monitor. And of course, ram. Ram will be giving you display for your monitor, and for running tasks.
For more components, you would need a hard drive, or an SSD, which will store your files and operating system. And of course, a keyboard, mouse, and monitor.
Answer:
LIKE.
Explanation:
A structured query language (SQL) can be defined as a domain-specific language designed and developed for managing the various data saved in a relational or structured database.
In Computer programming, any word restricted for use, only in object names because they belong to the SQL programming language are called reserved word.
Hence, these reserved words can only be used as the name of an object but not as an identifier e.g the name of a function, label or variable.
Some examples of reserved words in structured query language (SQL) are UPDATE, GROUP, CURRENT_USER, CURRENT_DATE, CREATE, DELETE etc.
Hence, SQL allows the use of special operators in conjunction with the WHERE clause. A special operator used to check whether an attribute value matches a value contained within a subset of listed values is LIKE.
