Answer: A. passive attacks
Explanation:
Passive attack is a type of attack where by a system is tracked and scanned to determine how vulnerable it is and to also detect open port. The major purpose of a passive attack on a network is to gain access to the information of the target without altering the data.
A passive attack on a network may not be necessarily malicious, it is a type of network attack that is very difficult to detect.
Methods of carrying out passive attacks.
•War driving: scanning of networks is carried out to detect Wi-Fi that are vulnerable.
•Dumpster driving: Attackers or intruders search for information from discarded computers and
other gadgets, those information can help to attack a network.
Answer:
31 bits.
Explanation:
Given, total number of registers = 55
Total instructions = 60
Size of memory = 16 KB
Now, no of registers are 55. We find the next greater or equal power of 2 which is 64 = 26. Hence, 6 bits are required to represent a register operand.
Number of instructions = 60. We find the next greater or equal power of 2 which is 64 = 26. Hence, 6 bits are required to represent a instruction.
Size of memory = 64 KB = 26 * 210 * 23 bits = 219 bits. Hence, 19 bits are required to represent a memory location.
Now, an instruction has 2 parts, opcode and operand. As given there are only two address instructions which are memory operand and register operand.
Hence, total bits would be: 6 bits (opcode) + 6 bits (register operand) + 19 (memory operand) = 31 bits.
Answer:
For an Ominous mood, the artist must have to use the big charades clip as it is a dramatic scene to manipulate the feeling.
Explanation:
Light is a way to manipulate the mood, but analyzing only the light to create an ominous feeling is the big charades, which is a word represented by a picture, or action, or a game in which players try to guess a word from the work of another player.
It is an act to make something different when light element use by film artists.
