Answer: E) The CPU executes the instruction by performing ALU operations.
Explanation: The execution cycle is of three stages namely; fetch, decode and execute. These are the functions that the CPU carries out from the time of boot-up up until it's shut down.
At the fetch stage, the computer retrieves program instructions from its memory register, at the decode stage; the decoders interprets the instructions from the instructions register and then the next stage will be the executions, at this stage; the interpreted instructions are then passed to relevant function units of the CPU to carry out the required instructions.
E.g mathematical and logic functions are passed on the ARITHMETIC AND LOGIC UNIT(ALU) to perform.
Answer:
The answer to this question is given below in the explanation section
Explanation:
There are different forms control. for example HTML form controls are:
-
Text Input Controls.
- Checkboxes Controls.
- Radio Box Controls.
- Select Box Controls.
- File Select boxes.
- Hidden Controls.
- Clickable Buttons.
- Submit and Reset Button.
to take input from the user and store it into the variable, mostly text input form control is used.
however, you can also use text input, checkbox, radio button as a control to take input from the user and store the input value in some variables.
Answer:
The AES decryption time is 8 minutes
Explanation:
GIVEN THAT:
The 1 GByte is equal to 230 bytes and equal to 233 bits
The RSA decryption time is calculated as = 233 / (100*230 )
= 83886. 06 seconds
= 23 hours
The RSA decryption time is 23 hours
The AES decryption time is calculated as = 233 / (17 * 230 )
= 481.81 seconds
= 8 minutes .
The AES decryption time is 8 minutes
