Answer:
a. PCI express
Explanation:
<em>PCI express</em> (Peripheral Component Interconnect Express) is a high speed serial bus and commonly used motherboard interface for Graphics card, wifi, SSDs and HDs hardware connections. Simple PCI can also be used but PCI express has more error detection accuracy lesser number of I/O pins and better throughput as compared to simple PCI.
The program is an illustration of loops and conditional statements
<h3>
Loops</h3>
Loops are used to perform repetitive operations.
<h3>
Conditional statement</h3>
Conditional statements are used to make decisions
<h3>The python program</h3>
The program in Python, where comments are used to explain each line is as follows.
#The following is repeated 5 times; i.e. the rows
for i in range(5):
#The following is repeated 5 times; i.e. the columns
for j in range(5):
#For rows 2 and 5
if i == 1 or i== 3:
#For columns 1 and 5
if j == 0 or j == 4:
#This prints *
print('*',end='')
#For other columns
else:
#This prints an empty space
print('',end=' ')
#For other rows
else:
#This prints *
print('*',end='')
#This prints a new line
print()

Answer:
Explanation:
Part a)
_______________ ____________ _____________ ___
TAR | /\ \/ /\ \/ /\
|//////////|____________|____________|_____________|__________|
0 600 800 600 800 600
PWM Duty Cycle = 200/800 = 25%
Part b)
______________ _________________ _________ _________________
TAR | \/ /\ \/ /\ \/
|//////////|_________|_________________|__________| _______________|
0 600 800 600 800 600
PWM Duty Cycle = 600/800 = 75%
Generally I'd recommend not buying one online, tends to be cheaper from a shop - and better used, although their are some risks with 2nd hand devices, I think the big price cut it worth it.
If you did want to buy online, maybe Amazon or Ebay?
