Answer:
Radius = 14 cm = 0.00014 km
Circumference = 2πr = 2 × 22/7 × 14/100000 = 0.00088 km
As it went thousand times , distance covered = 0.00088 × 1000 = 0.88 km
Answer:
Zero-day exploits
Explanation:
Zero-day exploits refers to recently found vulnerabilities in a computer software program that has been in existence but was hitherto not known and addressed by the software security experts, however, these vulnerabilities were known to hackers. While the existence of these "loop-holes" in the software can go on unnoticed for several years, hackers can take advantage of it to cause harm to the computers' programs and data.
When these attacks occur, it is called a zero-day because the attack took place on the very day that the loop-hole was discovered in the software. So exploitation has already taken place before a fix is carried out.
Answer:
a) TRUE.
Explanation:
The statement is true.We can declare a variable but not initialize it there we can initialize it afterwards when we want to use.On declaring the variable type it tells the compiler to reserve the memory according to the size required for the data type.When we initialize the memory is allocated to that variable.
