Answer:
It's easier to define text-based programming languages. These are languages that are typed using a keyboard and stored as text files. A graphical or visual language typically uses drag and drop rather than typing. It may use icons or textual labels on blocks or elements.
Answer:
The answer to this question is that none of the following will give syntax error.All of them will get executed.
(0 < num)&& (num <12)
0 < num <12
0 < num&& num < 12
num > 0&& num <12
There is no syntax error i have checked on the compiler also.But logically we take variable on the left side of the comparison operator and the value to the right of the operator.
Answer:
General process of creating a data flow diagram:
Data flow diagram are used to represents the flow of data graphically and it is divided into physical and logical parameters. For creating the data flow diagram the steps involved are:
- Select the data and name the DFD.
- In DFD add the entity for start the process and add that process in data flow diagram.
- Add a data store and continuous adding that data into DFD.
- Now, adding the data flow in DFD and name the data.
Answer:
16 RAM chips
Explanation:
To calculate the number of RAM chips needed, we divide the total size of the main memory by the size of each RAM chip. Hence:
Number of RAM chips required = Main memory size / size of one RAM
2M = 2²¹, 16 = 2⁴, 256K = 2¹⁸, 8 = 2³
Hence:
Number of RAM chips required = (2²¹ * 2⁴) / (2¹⁸ * 2³) = 2⁴ = 16
Therefore 16 RAM chips are necessary
By maybe telling the principal, block the number, and delete it.
