Answer: PC servers

Explanation: PC(Personal computer) servers are the helps in the utilization of the network services to the software and hardware of the computer. It manages the network resources . In the past time ,Mindrange computers, mini computers etc are present time's PC servers.

Other options are incorrect because laptops ,PDA(Personal digital assistant) or tablets are the modern version of the computer units that are portable and compact with fast processing. Thus the correct option is option PC servers.

What is aperture priority mode? When might you use this mode on a camera? What is depth of field? How can you adjust the depth o
raketka [301]

Answer:

Please check explanation

Explanation:

We abbreviate aperture priority by A or Av( which is used for aperture value) on the camera mode call up, which is an adjustment on some of the cameras which leverage the user to adjust the certain value of the aperture or the f-number as meanwhile the camera adjust the speed of the shutter ensuring it matches it, and which results in a good exposure depending on the condition of the light  as being measured via the light meter. And this is not the same as the manual mode, in which the user is compelled to make the decision for both the values, the priority of the shutter, the location the user selects the shutter speed while the camera picks up the correct aperture, as well as the program state, where camera picks each of them.

So the first two questions are answered. Let's see the third, the depth of the field.  It is the distance from the nearest to the furthest objects which provides an image being selected for being at the focus in a camera.

Hence the depth of the field means the range of the sharp focus in a certain photograph. And while you shoot with the help of the larger camera like the DSLR, you will be able to adjust the depth through the adjustment of the aperture of the lens. The aperture is nothing else but the opening within the lens which manages the amount of the light that is permitted via the lens.

Now come to the fifth question. The shutter speed and the aperture are being related directly. It improves the aperture (by a stop). And each of them comes up with the very best exposure through the permitted weight of light.

And both of them are related to each other in an inverse proportion. And both of them must be balanced for ensuring that the image is not being exposed or less exposed to the permitted light. And when the aperture is increased the shutter speed increased for balancing it as well as vice versa.

Landscape mode:

It is the kind of page orientation that prints out the picture in a horizontal manner rather than in a vertical manner. And it is being commonly used for printing the charts or various other types of pictures as well as the text which might not adjust properly with the page that is aligned vertically.

Consider the High Nikon DSLR. You need to hold down the "MODE" as meanwhile the rear control (dial)  is turned unless you view "A" over the LCD top. And your FCD then sets the aperture. And in almost all Canon SLRs as an example: You need to turn to "Av" your mode dial.

The results of these adjustments are certainly good.

And the shutter speed is being measured by the unit of time and ranges in less than fractions of one second. And as we say that the shutter speed is "5000", it means its 1/30000 th of a  minute. And the shutter speed which is of one second or more in length is being marked as a'. One example is 16'.

How we measure aperture. And what it means:

It is being measured with the help of the f-stop scale. And on the digital camera, you will find 'f/' which is being followed by an integer. And this f-number indicates the wideness of the aperture. As well as the size does affect the exposure as well as the field depth of the resultant image.

Now come to why we should learn to control the shutter speed and the aperture.

You should know that by selecting the shutter speed you permit yourself to freeze or otherwise blur motion, and sometimes you would like to do the first one or the second one. And the aperture permits you to select the field depth to either blur the background or make it sharper.

Thus, now you have an idea of each of the modes, and their merits. And if you will ask the best one, he will be up with the aperture priority or with auto ISO and full manual. If you are up with some specific requirements, then you should have a full manual mode in automatic mode, and that will be quite handy. You certainly need to learn by heart how to make use of the full manual, as it will improve your understanding of the photography, however, the semi-automatic mode is certainly your best friend.

And yes, as well as its a very great feeling. Its certainly quite hard to take the photographs of still objects while you are riding.

Some of the things that make it hard to take the action photographs are like the object, or the animal can move as well as you need to set the shutter speed as well as the aperture speed quite swiftly. Also, you need to focus your camera for ensuring a very good picture and ensure its not blurry or like the picture is out of the focus.

In night photography, the camera might shake because of the very low ambient brightness, the camera might move for very slow shutter speed. Various other challenges are the improper focus, white balances, less exposure, etc,

That solves all the questions asked.

anygoal [31]

Answer:

The answer to this question is "The main closet or telecommunications closet".

Explanation:

A multimedia terminal or multimedia terminal adapter (MTA) is also known as a Landline modem that operates just like a wireless router, but in terms of high-speed Internet, an MTA can provide Home Phone service only.

  • In the case of a significant power failure, MTAs have only a backup battery that will fuel the MTA for many hours.
  • This device is used to connect to a main or telecommunications closet.

If a 60 lb. load is placed on the platform, what will the pressure gauge reading be if the piston area is 5 sq.in? Give your ans
Doss [256]

Answer:

The pressure gauge reading will be;

12 psi

Explanation:

The question relates to relationship of pressure and area

The given parameters for the measurement are;

The weight of the load = 60 lb

The required area of the piston = 5 in.²

Pressure exerted by a force can be defined as follows;

Pressure =  \dfrac{Force}{Area}

The weight of the load = The force applied by the load

Therefore;

Pressure =  \dfrac{Force}{Area} = \dfrac{60 \ lb}{5 \ in.^2}  = 12\dfrac{lb}{in.^2} = 12 \ psi

The gauge reading will be 12 psi.

List the three control problems associated with competingprocesses and briefly define each.
hjlf

Answer and explanation :

the three control problems associated with competing process are

  • MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
  • DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
  • STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing  then low priorities process have to wait for very long time this is called starvation
