The feature to restrict values allowed in a cell and need to create a drop-down list of values from which users can choose in the above scenario is data validation.
<h3>What is data validation?</h3>
Data validation is a term that connote the act of monitoring the truthfulness and quality of source data before one can make use of it, importing or even process data with it.
Note that The feature to restrict values allowed in a cell and need to create a drop-down list of values from which users can choose in the above scenario is data validation as it ensure that users can make their own choice.

Answer:
False
Explanation:
If your computer requires that you install memory in pairs you should always keep in mind that
1. Both are the same type(DDR4+DDR4, DDR3+DDR3, DDR2+DDR2...)
2. Both are the same size (2GB+2GB, 4GB+4GB, 8GB+8GB...)
3. Both are the same speed (800MHz+800MHz, 1666MHz+1666MHz, 3200MHz+3200MHz...)
This is important, because of the predefined slots that are located on the Motherboard.
Although you can change the RAM speed from the BIOS you can not change the predefined slot values
Answer:
In the HC12 MCU, the starting address of interrupts is stored in the vector table as a vector. The ISR or interrupt service routine fetches the vector of the interrupt to be executed.
Explanation:
The HC12 or 68HC12 microcontroller was developed by Motorola, its controllers have a clock speed of between 8 to 33MHz.
The MCU stores interrupt events in a vector table where the interrupt service routine fetches enabled interrupt to execute.
When an interrupt is detected, the MCU stores all its registers in a stack to be able to return to the program it was previously running, then it disables the maskability flag register to prevent another maskable interrupt from occurring during the current interrupt execution.
The MCU interrupt service routine fetches the required interrupt from the vector table. After the interrupt is executed, the mask flag is enabled and the MCU retrieves or returns back to the previous program in the stack.
