Which layer of the osi model adds source and destination mac addresses to frames?
Answers
The Data Link layer, layer 2 of the OSI model, adds source and destination MAC addresses to frames. The primary responsibility of the Data Link layer is to ensure that data is transmitted over the physical network media with reliability and efficiency.
It accomplishes this by encapsulating packets from the Network layer into frames, adding MAC addresses to the frames, and performing error detection and correction. The Data Link layer is also in charge of controlling access to the network media, which is accomplished through the use of Media Access Control (MAC) addresses. The Data Link layer, layer 2 of the OSI model, adds source and destination MAC addresses to frames. It performs two primary functions: encapsulation and error detection and correction. The Data Link layer encapsulates packets from the Network layer into frames and adds source and destination MAC addresses to the frames. It accomplishes this by splitting data into smaller frames that can be transmitted over the physical network media with reliability and efficiency. MAC addresses, which are unique identifiers assigned to network interface controllers (NICs) at the time of manufacturing, are used to identify the source and destination devices on the local network segment. The Data Link layer is responsible for controlling access to the network media and preventing collisions from occurring when multiple devices attempt to transmit data at the same time. This is accomplished through the use of Media Access Control (MAC) addresses, which are embedded in the frame header. When a device wants to transmit data over the network, it must first wait for a clear channel, which is signaled by the absence of any other transmissions on the network. Once the device has determined that the channel is clear, it can send its frame.

Answers
A compiler converts the programming instructions/code written by programmers into a language that a computer can understand and process.
Computer devices do not understand human language constructs and it is very difficult for humans to write operational codes in computers' understandable formats. Programming languages are designed for humans to read and understand easily. It is necessary that the program or source code is to be translated into machine language so that the computer can interpret and execute the program; since the computers only understand machine language. Thus, to solve this issue, the compiler comes into action. A compiler takes the program code/source code, and converts the source code to a machine language, called an object file, that a computer understands and processes as per the requirements.

what should appear in the last row of a transportation matrix?
Answers
The last row of a transportation matrix should contain the total supply available at each source.
A transportation matrix is a tool used in transportation or distribution problems to allocate goods or resources from multiple sources to multiple destinations. It consists of rows representing the sources and columns representing the destinations. The cells within the matrix represent the quantity of goods or resources to be transported from each source to each destination.
In the context of a transportation matrix, the last row represents the total supply available at each source. Each cell in the last row indicates the total quantity of goods or resources available at the corresponding source.
To calculate the values in the last row, you sum up the quantities from each source column. This provides an overview of the total supply available at each source and helps in evaluating the feasibility of meeting the demand at the destinations.
The last row is crucial for balancing supply and demand in transportation problems. It allows you to assess whether the total supply meets the total demand or if adjustments need to be made to optimize the distribution of goods or resources.
In conclusion, the last row of a transportation matrix should contain the total supply available at each source. It provides an overview of the total quantities available at each source and plays a significant role in balancing supply and demand in transportation or distribution problems.

More about lossless compressionA type of data compression known as lossless compression enables flawless reconstruction of the original data from the compressed data with no information loss. Since most real-world data exhibits statistical redundancy, lossless compression is feasible.
By utilizing a sort of internal shorthand to denote redundant material, lossless compression "packs" data into a smaller file size. Depending on the type of information being compressed, lossless compression can reduce an initial file that is 1.5 MB to roughly half that size.

Angela spent 1 hour 21 minutes less than Carl reading last week. Carl spent 47 minutes less than Pete. Pete spent 3 hours reading. How long did Angela spend reading?
Answers
Angela spent 52 minutes reading last week. Carl spent 133 minutes reading, which is 47 minutes less than Pete's 3-hour reading time.
Angela spent 1 hour 21 minutes (or 81 minutes) less than Carl. By subtracting 81 minutes from Carl's reading time of 133 minutes, we find that Angela spent 52 minutes reading. To find out how long Angela spent reading, let's break down the information given step by step.
Pete spent 3 hours reading.
Carl spent 47 minutes less than Pete. Therefore, Carl spent 3 hours * 60 minutes - 47 minutes = 180 minutes - 47 minutes = 133 minutes reading.
Angela spent 1 hour 21 minutes less than Carl. This means Angela spent 133 minutes - 1 hour 21 minutes = 133 minutes - 81 minutes = 52 minutes reading.
Therefore, Angela spent 52 minutes reading last week.

how are given an array s sisting of n strings. every string is of the same
Answers
We need to understand what an array is and how it works. An array is a data structure that can store a fixed-size sequential collection of elements of the same type.
"How are given an array s sisting of n strings," we need to understand what an array is and how it works. An array is a data structure that can store a fixed-size sequential collection of elements of the same type. In this case, the array s is made up of n strings, which means that it can hold n elements, each of which is a string.
To create an array s sisting of n strings, we can use the following steps:
1. Declare the array s with the desired size n. For example, if we want an array with 5 strings, we can write:
`string[] s = new string[5];`
2. Assign values to the elements of the array s. For example, we can write:
`s[0] = "Hello";`
`s[1] = "World";`
`s[2] = "How";`
`s[3] = "Are";`
`s[4] = "You";`
3. Now, the array s sists of the following strings: "Hello", "World", "How", "Are", "You".
We can access the elements of the array s by using their index, which ranges from 0 to n-1. For example, to access the first element of the array s, we can write:
`string firstElement = s[0];`
In conclusion, to create an array s sisting of n strings, we need to declare the array with the desired size n and assign values to its elements. We can then access the elements of the array by using their index.

require function is used in a way in which dependencies cannot be statically extracted
Answers
The "require" function is a built-in Node.js function that allows modules to be imported and used within a Node.js program. When using the "require" function, dependencies are typically statically extracted. This means that the code will analyze the module and determine what dependencies it requires, then include those dependencies in the final build.
However, there are some cases where the "require" function is used in a way in which dependencies cannot be statically extracted. For example, if a module dynamically requires other modules based on user input or some other runtime condition, it may not be possible to statically extract all of the dependencies.
When dependencies cannot be statically extracted, there are a few potential drawbacks. One potential issue is that the final build may not be self-contained, which can lead to issues with portability and deployment. Additionally, dynamically loaded modules can be more difficult to test, as it may not be possible to predict which modules will be loaded at runtime.

The size of a structure-type variable can be changed by changing the orders of the members in the structure, adding a member into the structure, or changing the computer from a 32-bit to a 64-bit processor.
Changing the structure members order can change the alignment of the data members and hence affect the size of the structure. Adding a new member into the structure will increase the size of the structure by the size of the new member. Changing the computer from a 32-bit to a 64-bit processor also changes the size of the data types and hence affects the size of the structure. However, changing a struct from containing one char followed by a int, to two chars followed by an int, will not necessarily change the size of the structure as the size of char and int data types remains the same.

Snapdragons show an inheritance pattern of incomplete dominance for flower color. Two pink snapdragons (RW) are crossed. What percent off the offspring are expected to be red 2.5 pts expected to be white What percent are expected to be pink ? What percent are ? ?
Answers
According to the question the expected percentages of the offspring's flower colors are: 25% red, 25% white, 50% pink.
In snapdragons, an inheritance pattern of incomplete dominance for flower color means that the heterozygous offspring will display an intermediate phenotype between the two homozygous parents. Let's assume that red (RR) represents the dominant allele for flower color, and white (WW) represents the recessive allele.
When two pink snapdragons (RW) are crossed, the possible genotypes of the offspring are RR, RW, and WW. The expected phenotypic ratios can be determined as follows:
- Red (RR): 25% (expected to be red)
- White (WW): 25% (expected to be white)
- Pink (RW): 50% (expected to be pink)
The pink phenotype arises due to the incomplete dominance, where the expression of both alleles (red and white) results in an intermediate color.
Therefore, the expected percentages of the offspring's flower colors are:
- Red: 25%
- White: 25%
- Pink: 50%
