A study that gathers data by looking back at the past is called a "retrospective" study or a "retrospective cohort study." In a retrospective study, researchers collect and analyze data from past events, records, or individuals to investigate the relationship between certain variables or outcomes.
This type of study involves examining existing data or historical records, such as medical records, surveys, or administrative databases, to assess the occurrence of an outcome and identify potential risk factors or associations .Retrospective studies are commonly used in various fields, including epidemiology, healthcare, social sciences, and market research. They allow researchers to study events or phenomena that have already occurred and retrospectively analyze relevant data to draw conclusions or identify patterns. However, it's important to note that retrospective studies have limitations, including potential bias in data collection, reliance on existing records that may lack comprehensive information, and the inability to establish cause-and-effect relationships. Nonetheless, retrospective studies provide valuable insights into past events and can generate hypotheses for further investigation.

Answer:
in times before the use of computers, technologist invented computers to function on disk operating systems, each computer was built to run a single, proprietary application, which had complete and exclusive control of the entire machine. the introduction and use of computer systems that can simply run more than one application required a mechanism to ensure that applications did not write over each other's data. developers of Application addressed this problem by adopting a single standard for distinguishing disk sectors in use from those that were free by marking them accordingly.With the introduction of a file system, applications do not have any business with the physical storage medium
The evolution of the file system gave a single level of indirection between applications and the disk the file systems originated out of the need for multiple applications to share the same storage medium. the evolution has lead to the ckean removal of data redundancy, Ease of maintenance of database,Reduced storage costs,increase in Data integrity and privacy.

In vivo exposure within systematic desensitization is real-life exposure.Systematic desensitization is a therapeutic technique commonly used in cognitive-behavioral therapy (CBT) to treat phobias.
In vivo exposure specifically refers to the real-life, physical exposure to the feared stimuli or situations. It involves directly facing the feared object or engaging in the feared activity in the actual environment where it occurs. For example, if someone has a fear of heights, in vivo exposure would involve gradually exposing them to heights in real-life situations, such as climbing a ladder or standing on a high balcony.On the other hand, imaginal exposure is a different technique within systematic desensitization that involves exposure to feared situations or stimuli through imagination or mental imagery. It is typically used when the feared stimuli cannot be easily replicated in real life or when it is impractical to expose the individual directly to the feared situation.

what is the simplest and least expensive of external drive arrays
The simplest and least expensive external drive array is a Direct Attached Storage (DAS) system.
A Direct Attached Storage (DAS) system is an external storage device that is directly connected to a computer or server. DAS systems are typically the simplest and least expensive form of external drive array, as they do not require additional network infrastructure or hardware. Instead, they connect to a computer via a USB, FireWire, or Thunderbolt port, providing additional storage capacity for the system.
DAS systems can be used for a variety of purposes, including backup and archiving, media storage, and expanding the storage capacity of a computer or server. They are often used by individuals or small businesses that need additional storage capacity but do not have the resources or infrastructure to support more complex external drive arrays, such as Network Attached Storage (NAS) or Storage Area Network (SAN) systems.
While DAS systems are relatively simple and inexpensive, they do have some limitations. They are typically not as scalable as other types of external drive arrays, and they may require additional management and maintenance if used for backup or archiving purposes. However, for many users, a DAS system provides a cost-effective and easy-to-use solution for expanding storage capacity and improving system performance.

compared with the tcp protocol, udp suffers from potential packet loss. true false
The given statement "compared with the TCP protocol, UDP suffers from potential packet loss" is False because UDP is a connectionless protocol that does not provide any guarantee of packet delivery or order.
This means that packets sent using UDP (User Datagram Protocol) may be lost or arrive out of order, leading to potential data loss or errors. However, this does not necessarily mean that TCP is always a better option. TCP, or Transmission Control Protocol, is a connection-oriented protocol that provides guaranteed packet delivery and order.
While this may seem like a clear advantage over UDP, TCP also comes with added overhead and potential delays due to the need for establishing and maintaining a connection. Furthermore, in some applications such as real-time video streaming or online gaming, a small amount of packet loss may be acceptable if it allows for faster transmission and reduced latency. In these cases, UDP may be the preferred protocol.
Ultimately, the choice between TCP and UDP depends on the specific requirements and constraints of the application or network being used. It is important to carefully consider the trade-offs between reliability and efficiency in order to select the best protocol for a given scenario.
