Primary storage is typically memory that is volatile (meaning it requires power to keep data) and holds data that is in active use (the operating system, any applications that might be open, and user files that may be edited or read), the most common example of primary storage is RAM. Primary storage is much faster to access then any other type of storage.

Secondary storage is memory that is non volatile (which means the computer can be switched off and the storage will retain the data) and is used to store things like the operating system and any user data/applications when the computer is off, secondary storage typically has a much larger capacity then primary memory. Secondary storage examples include a hard drive or SSD.

Off-line storage is typically comprised of secondary storage devices that are stored in a separate location from the main computer, this is to ensure that in the event of an accident (e.g. A fire that damages the computer) there is a backup of the most important data. An example of off-line storage could be a service like dropbox (Note that off-line refers to not being on site and not a connection to the internet).

<span>Summary: Primary storage is fast and small, Secondary storage is large and slow, Off-line storage is secondary storage that can't (always) be written to (as the drive is in a separate location) and is more secure.</span>

What are the limitations of the ASCII character set? State why it is limited in this way?
dedylja [7]
The problem with ASCII or extended ASCII is that the ASCII system can only represent up to 128 (or 256 for EASCII) different characters. The limitation on the number of character sets means representing character sets for several different language structures is not possible.

Its an HTML5 anyone kwons
Aleksandr [31]

Answer:

1 will be stored in result

Explanation:

Given

The lines of code

Required

Determine the value stored in result

The value stored in result is determine by the condition (x<3 && y ==6)

In the first line, the value of x is 2 and the value of y is 6

So: x<3 is true because x = 2 and 2 is less than 3

y == 6 is also true because y = 6 and 6 is equal to 6

So, the condition (x<3 && y ==6) is true and true will be saved in variable result

Because result is a Boolean variable which can only take true or false value

1 represents true

0 represents false

<em>So, 1 will be stored in result</em>

What can be controlled through IoT? Choose four answers.
BaLLatris [955]

Answer:

Door locks

Light switches

Security cameras

Thermostat

Explanation:

IoT is internet of things that means network of different things that are interconnected through internet and make the decision with the help of Electronic sensors. The sensor sense the data from environment at different times and send this to the cloud (that may be the server). On the basis of this data different devices such as door looks, light switches, security cameras and thermostat take decisions with the help of controllers and change their current state.

<u>For Example</u>

In case of door look, there may be sensor that is sensing the finger prints of the user and after recognizing the person the door will be unlock. If unauthenticated user will try to open the lock a message has been sent to concerned. The training data of the the authorized persons is saved on the cloud, whenever someone tries to access, the data from sensor and cloud send to controller for making comparison and decision. So we can say that Door lock can be controlled IoT.

In case of light switches, there are few sensor available to sense the intensity of life. Different training values of that sensors are stored on the cloud. Whenever these sensors sense the light intensity, they send the data to the cloud contentiously, whenever the data match with darkness intensity, a signal has been send from controller to the switch to ON the lights.

Same as in cameras and Thermostat both are sending data to the cloud and controller. With the help of different image processing techniques and sensor camera will take the decision related to face recognition. Thermostat devices are also on and off by variation of temperature.

A good sentence about art
victus00 [196]

Answer:

Art, in its broadest sense, is a form of communication. It means whatever the artist intends it to mean, and this meaning is shaped by the materials, techniques, and forms it makes use of, as well as the ideas and feelings it creates in its viewers . Art is an act of expresThe three classical branches of visual art are painting, sculpture, and architecture. Music, theatre, film, dance, and other performing arts, as well as literature and other media such as interactive media, are included in a broader definition of the arts.

sing feelings, thoughts, and observations.

Now, remove any element founded in creativity, art and design, and all that remains are piles of materials that require human imagination and visual thinking. Art forces humans to look beyond that which is necessary to survive and leads people to create for the sake of expression and meaning.

a 50.5 force is applied to a golf ball generating an initial acceleration of 15 m/s2 caculate the mass of the golf ball.
siniylev [52]

Answer:

Mass = 3.37 Kg

Explanation:

<u>Given the following data;</u>

Force = 50.5N

Acceleration = 15m/s²

To find the mass of the golf ball;

Force is given by the multiplication of mass and acceleration.

Mathematically, the formula for force is;

F = ma

Where;

  • F represents force measured in Newton.
  • m represents the mass of an object measured in kilograms.
  • a represents acceleration measured in meter per seconds square.

Making mass (m) the subject of formula, we have;

Mass (m) = \frac{F}{a}

Substituting into the equation;

Mass (m) = \frac{50.5}{15}

<em>Mass = 3.37 Kg</em>
