<u>Students who have the same name may be confused with each other</u> is the best statement that best describes the problem that happened due to the fact that neither data source uses a unique id number for each student.

Define data source.

The term given to the <u>connection established from a server to a </u><u>database </u>is Data Source. When constructing a database query, the name is frequently utilized. <u>There is no requirement that the database filename and the data </u><u>source </u><u>name match</u>.

A DSN of the school may be configured for a database file with the name friends.mdb, for instance. <u>In a nutshell, a data </u><u>source </u><u>is the place, physical or digital, where the relevant data is kept in a data table, data object, or other storage type</u>.

Musya8 [376]

Answer: (B) Lossless compression

Explanation:

 According to the question, the given technique is the example of the lossless compression. The lossless compression is one of the technique that decompress the data into the original data form without any type of losses.

The lossless compression is the technique that usually compress the data, text and the databases. This technique also improve the compression rate helps in reconstruct the original data. It is used in various types of encoding methods, GNU tool and zip file.

Vaselesa [24]

A type of service which offers a preconfigured testing environment for application developers to create new software applications is: B - Platforms as a Service (PaaS).

<h3>What is cloud computing?</h3>

Cloud computing can be defined as a type of computing service that requires the use of shared computing resources over the Internet, rather than the use of local servers and hard drives.

<h3>The categories of cloud service.</h3>

Generally, cloud computing comprises three (3) service models which includes the following;

  • Infrastructure as a Service (IaaS).
  • Software as a Service (SaaS).
  • Platform as a Service (PaaS).

In conclusion, a type of service which offers application developers a preconfigured hosting and testing environment to create new software applications is Platforms as a Service (PaaS).

Given six memory partitions of 300 KB, 600 KB, 350 KB, 200 KB, 750 KB, and 125 KB (in order), how would the first-fit, best-fit,
Inga [223]

Answer:

In terms of efficient use of memory: Best-fit is the best (it still have a free memory space of 777KB and all process is completely assigned) followed by First-fit (which have free space of 777KB but available in smaller partition) and then worst-fit (which have free space of 1152KB but a process cannot be assigned). See the detail in the explanation section.

Explanation:

We have six free memory partition: 300KB (F1), 600KB (F2), 350KB (F3), 200KB (F4), 750KB (F5) and 125KB (F6) (in order).

Using First-fit

First-fit means you assign the first available memory that can fit a process to it.

  • 115KB will fit into the first partition. So, F1 will have a remaining free space of 185KB (300 - 115).
  • 500KB will fit into the second partition. So, F2 will have a remaining free space of  100KB (600 - 500)
  • 358KB will fit into the fifth partition. So, F5 will have a remaining free space of 392KB (750 - 358)
  • 200KB will fit into the third partition. So, F3 will have a remaining free space of 150KB (350 -200)
  • 375KB will fit into the remaining partition of F5. So, F5 will a remaining free space of 17KB (392 - 375)

Using Best-fit

Best-fit means you assign the best memory available that can fit a process to the process.

  • 115KB will best fit into the last partition (F6). So, F6 will now have a free remaining space of 10KB (125 - 115)
  • 500KB will best fit into second partition. So, F2 will now have a free remaining space of 100KB (600 - 500)
  • 358KB will best fit into the fifth partition. So, F5 will now have a free remaining space of 392KB (750 - 358)
  • 200KB will best fit into the fourth partition and it will occupy the entire space with no remaining space (200 - 200 = 0)
  • 375KB will best fit into the remaining space of the fifth partition. So, F5 will now have a free space of 17KB (392 - 375)

Using Worst-fit

Worst-fit means that you assign the largest available memory space to a process.

  • 115KB will be fitted into the fifth partition. So, F5 will now have a free remaining space of 635KB (750 - 115)
  • 500KB will be fitted also into the remaining space of the fifth partition. So, F5 will now have a free remaining space of 135KB (635 - 500)
  • 358KB will be fitted into the second partition. So, F2 will now have a free remaining space of 242KB (600 - 358)
  • 200KB will be fitted into the third partition. So, F3 will now have a free remaining space of 150KB (350 - 200)
  • 375KB will not be assigned to any available memory space because none of the available space can contain the 375KB process.
