}
return 0;
}
When entering a function or formula in a cell, which of the first character you must type =
Answer:
c. An active attack
d. A passive attack
Explanation:
Traffic flow analysis is a cyber attack method of acquiring information by intercepting and examining messages so as to decode them by analysing patterns in the way the messages are communicated.
Traffic flow analysis can either be active or passive depending on if the attacker alters communication in the case of active analysis or simply extracts information in case of passive analysis.
An i/o system call returns one-bit information about the call's status, Therefore the given statement is true.
<h3>What is an i/o system?</h3>
- I/O (Input/Output) is a type of data processing system that sends and receives data from a computer hardware component, device, or network. A network allows data to be sent between devices. Computers would be unable to communicate with other systems or devices if I/O was not present.
- The primary function of an i/o system is processor communication, which includes a variety of tasks such as data transfer between the processor and an I/O module, accepting and decoding commands sent by the processor, reporting current status, and the ability for the I/O module to recognize its own unique address.
- A system call allows a user program to communicate with the operating system. The program requests a number of services, and the operating system responds by invoking a series of system calls to fulfill the request.
