2. You have a faulty hardware specifically your bootable harddisk, corrupted or malfunctioning. You have to reformat and correct the bios installed on the disk.
3. You have not selected correct bootable device. - Select the correct harddisk, if you have partition, be sure to select the one with the Operating system is installed to.
Hi;
In the question, Robert gives the explanation that there is an error in the BIOS. A BIOS (Standing for Basic Input & Output System) is a ROM chip, and is vital for the computer to initialize devices such as RAM, the CPU, etc. If there is ever an error there, a computer simply cannot boot.
From the options given, your answer given would be C. ROM.
I hope this helps!
Answer:
thick
Explanation:
i took the test and got it right
Answer:
Following are the code to this question:
list_val = input()#defining a integer variable for input value
test_grades = list(map(int, list_val.split()))#defining test_grades as a list
sum_extra = -999 #defining sum_extra that holds negative integer value
sum_extra = 0#defining sum_extra that holds value
for y in range(len(test_grades)):#defining a for loop to check range of list
if(test_grades[y] > 100):# defining if block that check list value is greater then 100
sum_extra = sum_extra + (test_grades[y] - 100)#use sum_extra variable to hold extra value and add this value
print('Sum extra:', sum_extra)#print value
Output:
101 83 107 90
Sum extra: 8
Explanation:
In the above code a, "list_val" variable is declared, that uses an input method to input the values and declared a "test_grades" variable that uses a list method to add all values in the list.
In the next step, the "sum_extra" variable is declared, which holds some values and defines a for loop to check the range of the "test_grades", and define a if block, that checks list value is greater than 100. If the condition is true, it will remove the extra value, and add it into the sum_extera variable and add its value, and at the last use, print variable to print its value.
Answer:
A. Document camera
Explanation:
Document cameras, which are also known as visual presenters or visualisers, digital overheads, or docucams. They are real-time image capture devices for displaying an object to a large audience. Just like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, simply put, high resolution web cams, that is mounted on arms so as to facilitate their placement over a page.
This makes it easier and convenient for a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches.
In Theory, the document camera can be used to display all objects.
Gwen only needs to place her photo under a document camera and deliver her speech while the image will be displayed for the class.
