Answer:
C. spectrum used by most mobile phone firms that does not travel well through solid objects.
Explanation:
Obstructions on the path of radio waves can result to poor network coverage. This is also called Phone reception or coverage black spot. Just as an obstruction on the path of light waves causes the emergence of shadows, so also an obstruction from waves coming from the cell tower. Common culprits are windows, doors, roofing materials, and walls. These solid objects cause an interruption of network for network providers inside a building.
The use of antennas connected from outside the building to inside can be helpful in reducing the effect of this obstruction. Problems resulting could be low signal, difficulty hearing a caller at the other end, slow internet connection, etc.
Answer:
- var projected_fee = 6000;
-
- for(var i = 1; i <= 5; i++){
- projected_fee = projected_fee * 0.02 + projected_fee;
- console.log("$" + projected_fee.toFixed(2));
- }
Explanation:
Firstly, create a variable, projected_fee, and set the initial tuition fee value to it (Line 1).
Next, user a for loop that run for 5 times to repeatedly calculate the projected_fee based on 2 percent of increment rate (Line 4) and display the projected fee to console terminal (Line 5). The output should be
$6120.00
$6242.40
$6367.25
$6494.59
$6624.48
Answer:
Main memory is short term memory used by the CPU in processing commands, secondary memory is more permanent and used for storage.
Explanation:
Hey there so just a quick explanation here.
Main memory is not used for storage and secondary memory is not lost when the device's power is turned off.
That leaves you to two possibilities:
- Main memory is more permanent and used for storage, secondary memory is short term memory is used by the CPU in processing commands.
- Main memory is short term memory used by the CPU in processing commands, secondary memory is more permanent and used for storage.
The bolded bullet point is the correct answer because, main memory is what's know as RAM on your computer. It could either be 4GB, 8GB or maybe even 16GB of RAM. But this is known as Random Access Memory, this is data stored no on the hard drive but on the processor, only momentarily and used when the CPU needs it.
Secondary memory is your Hard Drive, typically 256GB, 500GB, or 1TB which is 1000GB's. But this data is stored on the Hard Drive or Solid State Drive (SSD) and it stays there even when the computer is shot off.
Kind of like our phones, we take pictures on a Friday night dancing with our friends, but our phone dies. Saturday morning we wake up and haha! We get to see all the funny pictures we took that night, so even though it shuts off, our data is saved and secured.
Hope this helps and Good luck !!
Happy Coding :)
It is just a declaration of an object variable, <em>person</em>, in JavaScript. Within a <em>person</em> object, there are key:value pairs. The code that you shared has the following keys: name, age, and favouriteFood, whereas the values of those keys are: Mike, 25, and pizza.
There is <em>no</em> alert statement in this code snippet; therefore, it <em>will not alert </em>anything. This code contains only a variable called <em>person, </em>and that's it!
