The ____________ layer is the bottom layer, whose job it is to convert bits into signals and vice versa.

Answers

Answer 1

The bottom layer of the OSI model is the Physical layer, which is responsible for converting bits into signals and vice versa.

This layer's primary purpose is to define the mechanical, electrical, and timing specifications necessary for data transfer from one computer to another over a physical medium.

Therefore, the Physical layer is also known as the Layer 1. It is responsible for the transmission and reception of raw data bits over a physical link, and it describes the electrical and physical representation of the data transmission and reception. This layer interacts with physical devices, such as repeaters, hubs, network adapters, and network connectors, among others. Thus, it is the layer that deals with the transmission of the physical layer's network's raw bitstream.

True or False: Notebook systems use a HALL effect sensor to detect when the LCD lid is closed and the sensor turns off the display

Answers

True. Notebook systems use a HALL effect sensor to detect when the LCD lid is closed and the sensor turns off the display.

Notebook systems typically use a HALL effect sensor to detect when the LCD lid is closed, which triggers the sensor to turn off the display. The HALL effect sensor detects changes in the magnetic field and is commonly used in electronic devices to determine the position and movement of objects. When the notebook lid is closed, the HALL effect sensor detects the change in magnetic field and sends a signal to the computer to turn off the display. This helps to conserve battery life and prevent damage to the LCD screen by preventing accidental activation while the lid is closed.

B. multicore processing

Multicore processing refers to the use of multiple processing cores within a single CPU. Each core can handle a separate task or set of tasks independently, allowing for increased efficiency and faster processing speeds. In multicore processing, the work is divided up between the cores by the hardware itself, rather than relying on the operating system to manage the distribution of tasks. This allows for better performance and can help to reduce the bottlenecking that can occur when a single processor is tasked with handling multiple threads of execution simultaneously. Overall, multicore processing has become an increasingly important part of modern computing, particularly in fields such as scientific computing, data analysis, and machine learning where complex calculations and data processing tasks are common.

(1 point) you are the head of a division of a big silicon valley company and have assigned one of your engineers, jim, the job of devising an algorithm to sort through an english text of n words and convert it into an esperanto document. jim comes up with an algorithm which takes 2n2 2n bit operations to handle an input text with n words. suppose the computers in your business can handle one bit operation every nanosecond (1 nanosecond

Answers

Answer:

Explanation:

a) 2n^2+2^n operations are required for a text with n words

Thus, number of operations for a text with n=10 words is 2\cdot 10^2+2^{10}=1224 operation

Each operation takes one nanosecond, so we need 1224 nanoseconds for Jim's algorithm

b) If n=50, number of operations required is 2\cdot 50^2+2^{50}\approx 1.12589990681\times 10^{15}

To amount of times required is 1.12589990681\times 10^{15} nanoseconds which is

1125899.90685 seconds (we divided by 10^{9}

As 1$day$=24$hours$=24\times 60$minutes$=24\times 60\times 60$seconds$

The time in seconds, our algortihm runs is \frac{1125899.90685}{24\cdot 60\cdot 60}=13.0312 days

Number of days is {\color{Red} 13.0312}

c) In this case, computing order of number of years is more important than number of years itself

We note that n=100 so that 2(100)^2+2^{100}\approx 1.267650600210\times 10^{30} operation (=time in nanosecond)

Which is 1.267650600210\times 10^{21} seconds

So that the time required is 1.4671881947\times 10^{16} days

Each year comprises of 365 days so the number of years it takes is

\frac{1.4671881947\times 10^{16}}{365}=4.0197\times 10^{13} years

That is, 40.197\times 10^{12}=$Slightly more than $40$ trillion years$

Steeler corporation is planning to sell 100,000 units for 2.00 per unit and will break even at this level of sales fixed expenses will be 75,000 what are the company's variable expenses per unit

Answers

Answer:

1.25 per unit

Explanation:

Number of units to sell = 100,000

Price per unit = 2

Fixed expense = 75000

At break even point :

Revenue = total expenses

Total expenses = fixed cost + variable cost

Let variable cost = x

Revenue = units to sell * price per unit

Revenue = 100,000 * 2 = 200,000

Hence,

Fixed cost + variable cost = Revenue

75000 + x = 200,000

x = 200, 000 - 75000

x = 125,000

Variable cost = 125,000

The variable expense per unit is thus :

Variable expense / number of units

125,000 / 100,000 = 1.25 per unit

[4 points] (extra credit) Now suppose you change your sensors so that at each time step t, they return the list of exact positions of the K cars, but shifted (with wrap around) by a random amount. For example, if the true car positions at time step 1 are c11=1,c12=3,c13=8,c14=5, then e1 would be [1,3,8,5], [3,8,5,1], [8,5,1,3], or [5,1,3,8], each with probability 1/4. Describe an efficient algorithm for computing p(cti∣e1,…,eT) for any time step t and car i. Your algorithm should not be exponential in K or T.
A description of the factor graph/Bayesian net used to model the problem, including any relevant variables and conditional probabilities. Also, a description of how you would use the factor graph to compute the provided probability. Note that you should try to simplify your expression for the probability as much as possible given the information provided.

Answers

To compute the probability p(cti∣e1,…,eT) for any time step t and car i, given the shifted sensor readings, we can utilize the factor graph representation of the problem. The factor graph consists of variables and conditional probabilities that capture the relationships between the true car positions and the observed sensor readings.

Variables:

cti: True position of car i at time step t.e1,…,eT: Observed sensor readings, which are lists of exact positions of the K cars shifted by random amounts at each time step.

Conditional Probabilities:

p(cti∣ct−1i): Transition probability of car i from time step t-1 to t.p(ei∣cti): Likelihood probability of observing the sensor reading ei given the true position of car i.

To compute p(cti∣e1,…,eT), we can employ the following steps:

Initialize the prior probability distribution p(c1) for the initial position of car 1 at time step 1. This can be determined based on prior knowledge or assumptions about the initial positions.Iterate over time steps t = 2 to T:

a.For each car i, compute the product of the transition probability  p(cti∣ct−1i) and the probability of the observed sensor reading p(ei∣cti) for the current time step t. This represents the joint probability of the current true position and observed sensor reading.

b. Normalize the computed joint probability values to obtain the conditional probability distribution p(cti∣e1,…,eT).

Repeat step 2 for each car i to compute the conditional probability distributions p(cti∣e1,…,eT) for all cars at time step t.

The algorithm described above has a computational complexity that is linear in the number of time steps T and the number of cars K, as it does not involve exponential calculations.

By leveraging the factor graph representation and conditional probabilities, we can efficiently estimate the conditional probability of the true position of a car at a given time step based on the observed sensor readings.
