An Information System is when key components such as hardware, software, data, and process are combined for collection, processing, and distribution of data. All of these scenarios mentioned on the choices above are considered transactions in an information system. There is an exchange of information that fully satisfies the request of a user and describes what transactions in information systems are. They are good examples of users entering information whether, physically or electronically, as data into computers. This data is then processed, and the database changes adjusted with some being made permanent.
Front-end the part with which the user interacts.
usually people who write this are called layout designers what languages are used (Html, css, js)
Beck-end The northern part is the structure of the site due to which it works, this includes the DBMS, logic, etc. which languages will be used(python, php, java)
People who can do both are called: full stack developr
Answer:
Differ in the quality of their transmission.
Explanation:
For example, when using the public phone box, wired transmission is done not wireless as in cell phones. Public phone box use electronic signals transmitted through a cable network to send voice data which are not very effective for long distance communication.
However, cell phones wirelessly send electromagnetic wave signal to a cell tower close to the caller and then the information is then transmitted to cell tower close to the receiver within a split of a second. This method of communication has much advantages.
Answer:
new_segment = [ ]
for segment in segments:
new_segment.append({'name': segment, 'average_spend': money})
print( new_segment)
Using list comprehension:
new_segment =[{'name': segment, 'average_spend': money} for segment in segments]
Using map():
def listing(a):
contain = {'name': segment, 'average_spend': money}
return contain
new_segment = [ ]
new_segment.append(map( listing, segment))
print(list(new_segment)
Explanation:
The python codes above create a list of dictionaries in all instances using for loop, for loop in list comprehension and the map function which collect two arguments .
