There are two types of secondary memories.
- RAM
- ROM
RAM:
- RAM stands for random access memory .
- It is expandable.
- we can do multiple things in it.
- Its erasable.
ROM
- ROM stands for read only memory.
- It is permanent .
- We can only read in it.
- Its permanent hence not removable.
Answer:
B. Application programming interface
Explanation:
An application programming interface (API) is an interface or communication protocol between different parts of a computer program intended to simplify the implementation and maintenance of software. An API may be for a web-based system, operating system, database system, computer hardware, or software library.
Answer:
<em>The registers that are compared are instructions 3 and 4</em>
<em>Explanation:</em>
<em>From the question given,</em>
<em>Recall that we need to explain what the hazard detection unit is doing during the 5th cycle of execution and which registers are being compared.</em>
<em>Now,</em>
<em>The instructions on the 5th cycle, at the stage ID/EX and IF/ID:</em>
<em>The instruction values are in ID/EX : sub $t2, $t3, $t6 (instruction 3)</em>
<em>The instruction values are in IF/ID: sub $t3, $t1 $t5 (instruction 4)</em>
<em>The register $t3 is compared in the instructions 3 and 4</em>
<em>The hazard detection unit between instruction 4 and 5t o be compared, it need to find out the values of $t1</em>

Answer:
def get_word(sentence, n):
# Only proceed if n is positive
if n > 0:
words = sentence.split()
# Only proceed if n is not more than the number of words
if n <= len(words):
return words[n-1]
return (" ")
print(get_word("This is a lesson about lists", 4)) # Should print: lesson
print(get_word("This is a lesson about lists", -4)) # Nothing
print(get_word("Now we are cooking!", 1)) # Should print: Now
print(get_word("Now we are cooking!", 5)) # Nothing
Explanation:
Added parts are highlighted.
If n is greater than 0, split the given sentence using split method and set it to the words.
If n is not more than the number of words, return the (n-1)th index of the words. Since the index starts at 0, (n-1)th index corresponds to the nth word
