They are the minimum amount of information that can be read from or written to a disk D. They hold the op code of the instruction being executed E. They compensate for the increased cost per bit of disks compared to registers.
Answers
The purpose of tag bits is to identify which cache line occupies a block of memory. Therefore, the correct answer is B.
Tag bits are part of the address used in a cache memory system. They are used to determine whether a requested block of memory is present in the cache or not. The tag bits are compared with the memory address to check for a match, indicating that the desired data is already stored in the cache.
If there is a match, it allows for faster access to the data. If there is no match, it indicates a cache miss and the data needs to be fetched from the main memory.
Therefore, b is correct.

Two identical bulbs are connected to a 12-volt battery in parallel. The voltage drop across the first bulb is 12 volts as measured with a voltmeter. What is the voltage drop across the other bulb?
Answers
Answer:
12 volts
Explanation:
The voltages across parallel-connected items are identical. (In fact, that's why you can measure the voltage by connecting the voltmeter in parallel with the circuit element.)
The voltage drop across each bulb is 12 volts.
A pump is used to extract water from a reservoir and deliver it to another reservoir whose free surface elevation is 200 ft above that of the first. The total length of pipes required is 1000 ft. All pipes are 12 in. in diameter and are made of galvanized iron with relative roughness equal to 0.0005 (you may assume fully-rough flow).

Answers
The H-Q relationship for the pump used to extract water from a reservoir and deliver it to another reservoir with a free surface elevation of 200 ft above the first can be determined based on the given information.
The H-Q relationship represents the relationship between the head (H) or pressure and the flow rate (Q) of the pump. However, the specific H-Q relationship for this pump is not provided in the question. It would typically be provided in the pump's performance curves, which describe the pump's characteristics and efficiency. To determine the H-Q relationship, one would need to refer to the pump's performance curves, which provide data on the pump's head and flow rate at various operating points. The curves are generated through testing and experimentation for specific pump models. Without the specific H-Q relationship provided in the question or the pump's performance curves, it is not possible to determine the exact relationship. The H-Q relationship can vary depending on the pump type, design, and operating conditions.

what is the rts/cts protocol designed to reduce or prevent?
a. negative acknowledgements
b. CRC (Cyclic Redundancy Check) errors
c. collisions
d. handshakes
Answers
The RTS/CTS (Request-to-Send/Clear-to-Send) protocol is designed to prevent collisions in wireless communication. Collisions occur when two or more devices try to transmit data at the same time, resulting in data corruption or loss.
The RTS/CTS protocol is used to avoid collisions by allowing a device to check if the wireless medium is free before transmitting. When a device wants to transmit data, it sends an RTS frame to the receiving device, requesting permission to transmit. The receiving device then responds with a CTS frame, indicating that it is ready to receive the data. This process ensures that only one device transmits at a time, preventing collisions and improving the overall efficiency of the wireless network.
While the RTS/CTS protocol does involve handshakes between devices, it is primarily designed to prevent collisions rather than improve handshaking. It also does not directly address negative acknowledgements or CRC errors. Instead, it focuses on avoiding collisions, which can be a significant issue in wireless networks with multiple devices competing for the same channel. By implementing the RTS/CTS protocol, wireless networks can reduce collisions, improve data transmission rates, and minimize the potential for data loss or corruption.

The industry is using a lot of new replacement refrigerants, therefore a technician should rely on system temperatures to make troubleshooting easier, hence the given statement is true.
As opposed to conventional refrigerants like R-12 and R-22, new replacement refrigerants have unique features. As a result, the system temperatures will also vary. For instance, because R-134a has a lower boiling point than R-12, the evaporator temperature will be lowered.

The big ben clock tower in london has clocks on all four sides. If each clock has a minute hand that is 11.5 feed in length, how far does the tip of each hand travel in 52 minutes?
Answers
Answer:
Updated question
The big ben clock tower in London has clocks on all four sides. If each clock has a minute hand that is 11.5 feet in length, how far does the tip of each hand travel in 52 minutes?
The distance traveled by the tip of the minute hand of the clock would be 62.59 ft
Explanation:
Let us assume the shape of the clock is circular.
the minute hand is equal to the radius = 11.5 ft
Diameter = radius x 2
Diameter = 11.5 x 2 = 23 ft
The distance traveled by the tip of the minute hand can be calculated thus;
the fraction of the circumference traveled by the minute hand would be;
52/60 = 0.8667
Circumference of the clock would be;
C = pi x d
where C is the circumference
pi is a constant
d is the diameter
C = 3.14 x 23
C = 72.22 ft
Therefore the fraction of the circumference covered by the minute hand would be;
72.22 ft x 0.8667 = 62.59 ft
Therefore the distance traveled by the tip of the minute hand of the clock would be 62.59 ft

Answers
The probability that one telephone call passes through the switchboard in three minutes is 1.49%.
Calculating the probability
Using the Poisson probability formula, we can calculate the probability of exactly one call passing through the switchboard in 3 minutes as follows:
P(X = 1) = (e^(-6) * 6^1) / 1!
Where
6 = 2 per minute * 3 minute
X is the number of calls passing through the switchboard in 3 minutes.
So, we have
P(X = 1) = (e^(-6) * 6^1) / 1!
= (0.00248 * 6) / 1
= 0.0149
Therefore, the probability that one telephone call passes through is approximately 0.0149, or about 1.49%.

Answers
Given the following data:
Mass of astronaut = 150-lbm.
Acceleration due to gravity on Moon = 5.48 ft/s².
What is weight?Weight can be defined as the force acting on an object or a physical body due to the effect of gravity. Also, the weight of a physical object (body) is typically measured in Newton or ounces.
How to calculate the weight of this astronaut?Mathematically, the weight force on a physical body can be calculated by using this formula:
W = mg
Where:
W represents the weight.m represents the mass.g represents the acceleration due to gravity.Substituting the given parameters into the formula, we have;
Weight = 150 × 1/32.2 × 5.48
Weight = 25.5 lbf.
For the weight on beam scale.A beam scale is a measuring instrument that is designed and developed to compare the masses of a physical body and as such, it's not affected by the variations in acceleration due to gravity. Therefore, the beam scale would read 150-lbf as it read on earth.
