Answer:
b. the interface between the hard disk and the system bus
Explanation:
A controller, in the most basic computing terms, is a hardware chip or card that falls between two hardware components. Thus, a computer’s motherboard will always have a controller that interfaces with RAM, hard disk, DVD drives or other hardware components. Being an interface between two hardware devices facilitate incoming and outgoing commutations. Option B therefore, is the correct answer because it interfaces between the hard disk and sytem bus, which are both hardware components.
Answer:
The SQL query is used to create a copy of a table like the 1_employee table in the SQL database.
Explanation:
create table copy_of_employees as select EMPLOYEE_ID, FIRST_NAME, LAST_NAME, DEPT_CODE, HIRE_DATE, CREDIT_LIMIT, PHONE_NUMBER, MANAGER_ID from l_employees;
INSERT INTO copy_of_employees SELECT * FROM l_employees;
SELECT * FROM copy_of_employees;
This SQL creates a table called copy_of_employees and copies the selected query of the 1_employees table and inserts it to the newly created table.
