suppose an ip packet is fragmented into 10 fragments, each with a 1% (independent) probability of loss. to a reasonable approximation, this means there is a 10% chance of losing the whole packet due to loss of a fragment. what is the probability of net loss of the whole packet if the packet is transmitted twice with the following assumptions? make sure to provide your assumptions, intermediate steps and formulation. partial credit will be provided. 6.1 assuming all fragments received must have been part of the same transmission? 6.2 assuming any given fragment may have been part of either transmission?
The probability that the packet is lost in both transmissions is [1 - (1 - 0.01)¹⁰]².
The probability that the packet is lost is 1 - (0.9999)¹⁰.
How to solve the probability6.1 Assuming all fragments received must have been part of the same transmission
The probability that a given transmission of the packet is received in its entirety is (1 - 0.01)¹⁰, because each fragment has a 1% chance of being lost.
So, the probability that a given transmission of the packet is lost is 1 - (1 - 0.01)¹⁰, because the packet is lost if any one of its fragments is lost.
The packet is transmitted twice. So, the probability that the packet is lost in both transmissions is [1 - (1 - 0.01)¹⁰]².
6.2 Assuming any given fragment may have been part of either transmission
In this case, the packet is received as long as at least one complete set of fragments is received across the two transmissions.
Each fragment has a 0.01 chance of being lost in a given transmission, so it has a (0.01)² = 0.0001 chance of being lost in both transmissions.
Therefore, each fragment has a 1 - 0.0001 = 0.9999 chance of being received in at least one of the two transmissions.
Since the packet consists of 10 fragments, the probability that the entire packet is received in at least one of the two transmissions is (0.9999)¹⁰.
So, the probability that the packet is lost is 1 - (0.9999)¹⁰.

TRUE / FALSE. evidence storage containers should have several master keys.
The statement "evidence storage containers should have several master keys" is false.
The reason for this is because the security and integrity of evidence are critical to maintaining a fair and just legal system. Evidence storage containers are designed to keep physical evidence secure and tamper-proof until it is needed in court. Therefore, it is important to limit the number of individuals who have access to the evidence storage containers.
Having several master keys would increase the number of people who can access the containers, which could lead to the possibility of evidence tampering or theft. Instead, evidence storage containers should have a limited number of keys that are held by authorized personnel only. Each key should be accounted for and kept secure to ensure that there is no unauthorized access to the evidence.
In conclusion, evidence storage containers should not have several master keys. This is because maintaining the security and integrity of the evidence is of utmost importance in the legal system, and limiting access to authorized personnel helps ensure that the evidence is protected.

Raid Level 3 interleaves data, one bit at a time, across all data drives (T/F)
False. RAID Level 3 does not interleave data one bit at a time across all data drives.
RAID Level 3 is a block-level striping with dedicated parity. It stripes data across multiple data drives at a block level, meaning that it divides data into fixed-size blocks and distributes them across the drives. However, instead of interleaving data one bit at a time, it interleaves data at the block level. Each block of data is written to a different data drive, and a separate dedicated parity drive is used to store the parity information for the corresponding blocks on the data drives.
The use of dedicated parity allows for efficient error correction and fault tolerance. If one of the data drives fails, the system can use the parity information to reconstruct the data on the failed drive. However, the requirement of a dedicated parity drive means that RAID Level 3 is not as efficient in terms of storage utilization compared to other RAID levels that distribute parity across all drives.

Trace the action
The binary search algorithm can be modified to handle arrays with even lengths by considering the upper of the two middle elements as the pivot. This modification ensures that the algorithm works correctly and efficiently for arrays of any length.
In the traditional binary search algorithm, the pivot is chosen as the middle element of the array. This works well for arrays with odd lengths, but poses a challenge when the array length is even. In such cases, there is no exact middle element. To address this, we can modify the algorithm to consider the upper of the two middle elements as the pivot.
When dividing the array in half during each iteration, we can calculate the middle index as (low + high) // 2. However, for arrays with even lengths, we can modify this calculation to (low + high + 1) // 2 in order to choose the upper middle element as the pivot. By making this modification, the binary search algorithm can handle arrays of any length correctly. This ensures that the search process efficiently narrows down the search space and accurately finds the target element, regardless of the array's length.

Assuming that the code is part of a larger program and the necessary variables have been properly initialized, let's consider what the value of EDI will be in each scenario.
1. If the user enters JAMES, the value of EDI will be 5. This is because the program will iterate through each character of the input string and increment EDI by 1 for each character read. So in this case, the program will read five characters (J, A, M, E, S) and increment EDI by 1 each time, resulting in a final value of 5.
2. If the user enters JENNY, the value of EDI will be 5 as well. The program will again iterate through each character of the input string, but this time it will only increment EDI if the character is not an "M". Since there is only one "M" in "JENNY" and it occurs in the third position, the program will increment EDI by 1 for the first two characters (J, E) and then skip incrementing for the "M". It will then continue incrementing EDI for the remaining characters (N, N, Y) until it reaches the end of the input string, resulting in a final value of 5.

raid connects several inexpensive hard-disk drives to one another
Yes, that is correct. RAID (Redundant Array of Inexpensive Disks) is a technology that allows multiple hard-disk drives to be connected and work together as one unit. This can increase the performance, capacity, and reliability of the storage system.
RAID is a storage technology that combines several physical hard-disk drives into a single logical unit. The purpose of RAID is to provide various advantages over using a single hard drive, such as increased performance, capacity, and fault tolerance. There are several different levels of RAID, each with its own characteristics and benefits. The most common levels of RAID are RAID 0, RAID 1, RAID 5, and RAID 6. RAID 0, also known as striping, splits the data across multiple disks to increase performance.
However, it does not provide any fault tolerance and is vulnerable to data loss if one of the disks fails. RAID 1, also known as mirroring, duplicates the data across multiple disks to provide redundancy. If one of the disks fails, the other disk(s) can still provide the data. However, it does not increase performance or capacity. RAID 5 and RAID 6 are similar to RAID 0 in that they split the data across multiple disks for increased performance. However, they also provide parity information that can be used to recover the data if one of the disks fails. RAID 5 requires at least three disks, while RAID 6 requires at least four disks. In summary, RAID allows multiple inexpensive hard-disk drives to be connected and work together as one unit, providing benefits such as increased performance, capacity, and fault tolerance. The specific benefits and characteristics depend on the RAID level used. RAID (Redundant Array of Independent Disks) is a technology that connects several inexpensive hard-disk drives to one another. The main purposes of RAID are to improve data redundancy, fault tolerance, and performance. There are different RAID levels (e.g., RAID 0, RAID 1, RAID 5) that determine how the data is distributed across the drives. In summary, RAID allows you to combine multiple hard drives to achieve better performance, reliability, and data protection.

Which of the following would be a preanalytical error related to specimen storage?
Preanalytical errors are errors that can occur before laboratory testing, and they include errors related to specimen collection, handling, and processing.
A preanalytical error related to specimen storage would be an error that occurs during the storage or transport of a specimen before it is tested in the laboratory. Examples of preanalytical errors related to specimen storage include:
Incorrect temperature - If a specimen is stored at the wrong temperature (for example, if a refrigerated sample is left at room temperature), this can affect the stability of the analytes in the specimen.
Delayed processing - If a specimen is not processed in a timely manner, this can lead to changes in the analyte concentrations due to ongoing metabolic processes or degradation of the specimen.
Contamination - If a specimen is not stored in a sterile container or in a way that prevents contamination, this can lead to inaccurate results.
Hemolysis - If a blood specimen is stored or transported improperly (such as being vigorously shaken), this can cause hemolysis, which affects the accuracy of certain laboratory tests.
