Explanation:
Typically, a DVD has more capacity them a CD because Digital versatile discs (DVDs) can store more information than compact discs (CDs) because they have smaller pits, placed closer together. It is the pattern of these pits burned onto a disc's surface that encodes the 1's and 0's a player translates into sound and/or images

Answer:
Factors that can affect drive thrashing are;
The computer memory modules
Hard drives
Running processes
Paging file
Explanation:
Drive thrashing also known as disk thrashing occurs due to over stressing the hard drives by moving data from the from virtual memory,(paging file) to system memory,(RAM) and back again such that the memory becomes exhausted resulting in slow performance or system halting.
Factors that can affect drive thrashing are the computer memory modules, hard drives, running processes, and paging file
When thrashing occurs, the computer performance is slowed down or halts as the hard drives resources has reached close to capacity.
Answer:
- letter_counts = {}
- string1 = "I have a dream"
-
- string1 = string1.lower()
-
- for x in string1:
- if(x == " "):
- continue
- if x not in letter_counts:
- letter_counts[x] = 1
- else:
- letter_counts[x] += 1
-
- print(letter_counts)
Explanation:
The solution is written in Python 3.
Firstly create a letter_count dictionary (Line 1)
Next, create a sample string and assign it to string1 variable and convert all the characters to lowercase using lower method (Line 4).
Create a for loop to traverse through each character in string1 and check if the current character is a single space, just skip to the next iteration (Line 7 -8). If the current character is not found in letter_counts dictionary, set the initial count value 1 to x property of letter_counts. Otherwise increment the x property value by one (Line 9 -12).
After completion of loop, print the letter_count dictionary. We shall get the sample output {'i': 1, 'h': 1, 'a': 3, 'v': 1, 'e': 2, 'd': 1, 'r': 1, 'm': 1}
