Consider the following pattern of branch outcomes: T, NT, T, T, NT. (T = Taken, NT = Not Taken) (a) (5 pts) What is the accuracy of always-taken predictors for this sequence of branch out- comes? (b) (5 pts) What is the accuracy of the 2-bit predictor for this sequence of branch outcomes? Assume the predictor starts in "strongly not-taken" state. 5 (c) (Extra Credit, 10 pts) What is the accuracy of the 2-bit predictor if this pattern is repeated forever (e.g., in an infinite loop)? (d) (Extra Credit, 10 pts) Briefly describe a predictor design that would achieve a perfect accuracy if this pattern is repeated forever. You predictor should be a sequential circuit with one output that provides a prediction (1 for taken, 0 for not taken) and no inputs other than the clock and the control signal that indicates that the instruction is a conditional branch.
Answers
the accuracy of this predictor would be 100%.
(a) The accuracy of always-taken predictors for this sequence of branch outcomes is 60%.This is because out of the 5 branch outcomes, 3 were taken (T), and 2 were not taken (NT). Therefore, the percentage of correct predictions by an always-taken predictor would be (3/5) * 100% = 60%.(b) The accuracy of the 2-bit predictor for this sequence of branch outcomes is also 60%.Assuming the predictor starts in the "strongly not-taken" state, the first branch outcome (T) would be mispredicted, so the predictor would transition to the "weakly taken" state.
The next branch outcome (NT) would also be mispredicted, so the predictor would transition to the "strongly not-taken" state. The third branch outcome (T) would be correctly predicted, so the predictor would transition to the "weakly taken" state. The fourth and fifth branch outcomes (both T) would also be correctly predicted, so the predictor would remain in the "weakly taken" state.
Therefore, the percentage of correct predictions by a 2-bit predictor would be (3/5) * 100% = 60%.(c) If this pattern is repeated forever (e.g., in an infinite loop), the accuracy of the 2-bit predictor would be 100%.This is because the predictor would eventually learn the pattern and transition to the "strongly taken" state after observing the first three branch outcomes.

Answers
Answer: Sound Theory
Explanation:
Just took the test
-K12 Student
The study of acoustic energy is part of sound theory.
What do you mean by Sound Theory?Sound theory refers to the scientific study of sound and its properties. This includes both the physical properties of sound and the way that it is perceived by humans and other animals. The study of sound is an interdisciplinary field that draws from physics, engineering, psychology, and biology.
In physics, sound is understood as a type of wave that travels through a medium, such as air, water, or solids. The study of these waves includes the measurement of their amplitude, frequency, and speed. Acoustic engineers use this knowledge to design and build systems that produce or transmit sound, such as loudspeakers, microphones, and soundproof rooms.
In psychology and biology, the study of sound focuses on how it is perceived and processed by the auditory system. Researchers in these fields study how sound is transformed into electrical signals in the ear and then processed in the brain. They also study how different sounds are perceived by humans and animals, and how this information is used to identify objects and navigate the environment.

An airport has an electronic system that randomly selects bags for extra security screening. Each bag has a 14\%14%14, percent probability of being selected for extra screening, and one bag being selected or not doesn't affect whether or not another bag will be selected.
Answers
The probability that the two bags are selected for extra screening will be 0.02.
How to calculate the probability?From the information, the airport has an electronic system that randomly selects bags for extra security screening and each bag has a 14% probability of being selected.
In this case,the probability of selecting 2 bags will be:
= P(bag) × P(bag)
= 14% × 14%
= 0.14 × 0.14
= 0.02
The probability is 0.02.

if t= [0 1 1 0] is a transformation matrix which expression correctly applies t to v?
Answers
The expression t * v applies the transformation matrix t to the vector v. The resulting vector is obtained by multiplying each element of v by the corresponding column of t and summing the results.
In this case, the transformation matrix t is given as [0 1 1 0], and let's say the vector v is [x y z w]. Multiplying t and v gives the expression [0*x + 1*y + 1*z + 0*w]. This simplifies to [y + z].
So, applying the transformation matrix t to the vector v results in a new vector [y + z]. The original vector v is transformed by adding the second and third elements together, while the first and fourth elements remain unchanged.

how will a stateful packet inspection (spi) firewall handle a packet containing a tcp syn segment?
Answers
A stateful packet inspection (SPI) firewall uses a method called dynamic packet filtering to examine not only the incoming packet, but also the state of the connection associated with the packet.
When a packet containing a TCP SYN segment arrives at an SPI firewall, the firewall examines the packet's headers to determine the source and destination addresses and ports, and checks to see if there is an existing connection in its state table. If there is no existing connection or the connection is closed, the firewall creates a new entry in its state table for this connection.
The firewall then sends a TCP SYN-ACK packet back to the originating device, which will respond with a final TCP ACK segment to establish the connection. If the firewall receives the final ACK segment, it updates the state table for the connection and allows the packets to pass through. If it does not receive the final ACK segment within a certain time, it may drop the packets and remove the connection from the state table to prevent unauthorized access.

Answers
Answer:
Doom (1993) Half Life (1998) Super Mario 64 (1997)
Explanation:
Doom and Half-Life were PC games.
Doom was an early 90s PC shooter that was "3d" it wasn't actually 3d but it used a unique rendering system to make it look 3d. It was a level to level shooter that also included secrets
Half-Life was a Actual 3D game and required quite a beefy Graphics card in your computer at the time to run it smoothly, It was a long story-driven game
Super Mario 64 was one of the first "True 3D" games on Home console because it was a launch title for the brand new N64 It utilized the hardware for a brand new experience for console players.
Most 80s games were even more primitive and were either Hosted in arcade cabinets at your local Arcade Such as Outrun (1986) (Btw great soundtrack!) or the NES that allowed you to play the Original few Mario games that were all 2D.
So one of the biggest Evolutions in 80s to 90s gaming is the introduction of 3D titles being able to run on good computers in the early 90s and home consoles could also run 3D titles at the end of the 90s

TRUE/FALSE. if two methods in the same class have the same name but different signatures, the second overrides the first.
Answers
The statement is false. You can override a superclass method by creating a new instance method in the subclass that has the same signature.
Every class derives from the Object class, either directly or indirectly. The subclass method overloads the superclass method if the signature of the methods in the two classes match. The second method replaces the first if two methods in the same class have the same name but different signatures.
If a method in your subclass has the same name and signature as a method in its superclass, the method in your subclass takes precedence. As a result, the method from the superclass is not inherited by the subclass.
