Answer:

Opcode = 3

Mode =2

RegisterRegister =7

AR = 20

Explanation:

a) Number of addressing modes = 4 = 22 , So it needs 2 bits for 4 values

Number of registers = 65 = 1000001 in binary , So it needs 7 bits

AR = 20

Bits left for opcode = 32 -(2+7+20) = 3

Answer:

the user should disable file and print sharing on the laptop

Explanation:

According to my research on information technology and cyber security, I can say that based on the information provided within the question in order to prevent this the user should disable file and print sharing on the laptop. This is because this file and printer sharing allows users to see your files that you have available as shared and copy or print those files. Which if they are sensitive data you should just disable this option so that people on the same network cannot see or access these files.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Marta_Voda [28]

Answer:

3% inflation rise. No correct cpi option

Explanation:

Consumer Price Index(CPI) is calculated by the Bureau of Economic Analysis and Statistics of a country monthly and annually.

Consumer Price Index(CPI) is used for measuring the changes in the price level of consumer goods and services purchased by households.

Calculating the consumer price index; price in 1964= $1.25, today price= $5.0.

Therefore, consumer price index= Price in today- price in 1964÷ price in 1964,.

Consumer Price index(CPI)= $(5-1.25)/1.25 = 3.75/1.25 = 3 Percent price inflation rise.

For the first cpi; 112-80/80= 0.4 percent( not equal to the 3 Percent inflation rise).

For the second cpi: 141.6-60/60= 1.36 Percent inflation rise(not equal to the 3 Percent inflation rise).

For the third CPI: 126.4-75/75 =0.68 percent inflation rise[not equal to the 3 Percent inflation rise].

For the third CPI: 108.5-90/90=0.21 percent inflation rise(not equal to 3 Percent inflation rise)

Therefore, none of the options are right.
