Answer:

Volatile storage is lost when a computer loses power.

Explanation:

There are different types of storage in the computer. We have those that stores permanently like the disk while we have those that are very volatile.

The permanent storage retain storage in the event of power failure but volatile storage is lost if there is power failure. Example of volatile storage in the computer is RAM

Answer:

Volatile storage is lost when a computer loses power.

Explanation:

Volatile storage, is storage that has not been transferred to a more long term form of storage. Volatile storage only retains its content while the system is being powered. This type of storage can be lost if power goes off and this makes evident, the need for care in storing additional data frequently as work is being done on a computer.  The most common type of volatile memory in a computer is the random access memory (RAM).

What is the exact number of bytes in system of memory that contains (a) 64K bytes (In Binary)(b) 32M bytes
VashaNatasha [74]

Answer:

64 K bytes = 65536 bytes

32 M bytes = 33554432 bytes

Explanation:

The question expect the number of bytes in binary instead of decimal. So this is important to understand that:

  • 1K bytes = 1024 bytes (in binary)

Therefore,

  • 64 Kb = 64 x 1024 =  65536 bytes

Using the similar calculation logic, we know

  • 1M bytes = 1024 x 1024 = 1048576 bytes (in binary)

Therefore,

  • 32 M bytes = 32 x 1048576 =  33554432 bytes

Explain demand paging with a proper example
julia-pushkina [17]
<h2><em><u>Demand</u></em><em><u> </u></em><em><u>paging</u></em><em><u> </u></em><em><u>:</u></em></h2>

<h3><em>In computer operating systems, demand paging (as opposed to anticipatory paging) is a method of virtual memory management. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it and that page is not already in memory (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults will occur until most of a process's working set of pages are located in physical memory. This is an example of a lazy loading technique.</em></h3>

Lori wants to set up a SOHO network in her apartment. The apartment comes with a Gigabit Ethernet network already installed. Lor
Yanka [14]

Connection to the gigabit ethernet network must be done with Cat6 Cable. Using the wireless ethernet router as the network device and connecting the cable to the printer must be done with Cat5e Cable.

We can arrive at this answer because:

  • The Cat6 Cable will be responsible for establishing a bridge between the gigabyte Ethernet and the network device, allowing data delivery to be made between the two systems.
  • This connection must be made with a wireless device, to keep it more stabilized and it needs, mainly, for the notebook to receive the internet signal. This will be done using the wireless ethernet router.
  • The printer needs a softer, less rigid connection, so a Cat5e cable will be a convenient option.

In this case, we can see that using these devices will allow Lori to have a more stable and efficient connection to meet her needs.

Which of the following tools and techniques shows theimpacts of one decision over another as well as the probability andcost of
Nezavi [6.7K]

Answer: Probability/impact risk matrix

Explanation: Probability/impact risk matrix is type of matrix that defines the probability as well as impact that depicts whether the risk is low ,high or moderate.

Impact matrix is sort of tool which helps in conversion of any plan into a action. Probability matrix help in defining the chances in defining the risk.The positioning of the impact value of risk is plotted  on the vertical axis and performance value on the horizontal axis.

Thus probability/impact matrix is the correct tool for the problem mentioned in the question.
