Answer:
Data type is an attribute of the data in the computer science. It basically guide the compiler and interpreter about the data utilization in the program. Data type basically define the operation, which can be done on given data.
There are different types of data types are as follow:
Integer data type: This type if data type basically represent the integer type of data value from largest to smallest order.
For example: int p = 10;
Real data type: This type of data type is used to represent the real type of number from largest to smallest range.
For example: float b = 17.6;
Autonomic computing???????????????????????????????
Answer:
A: Using Encapsulating Security Payload
B: Using MACs (Message Authentication Codes)
Explanation:
Data integrity means that, the data should be authentic and accurate. This data is not being attempted to change and it is as accurate as sent by the sender. In transmission path different protocols has been used to make sure and maintain the integrity of message or data.
We can perform this by using Encapsulating Security Payload
, where the data is encapsulate and hidden between security keys. This protocol ensures the integrity and confidentiality of data between sender and receiver.
MAC (Message authentication Codes) are small codes that are added along with the data while sending by the sender. These codes ensures the data integrity and protect it from the hackers. These codes make sure that data will not changed during transmission.
