a. Programmed I/O.
b. Direct Memory Access (DMA).
c. Polling.
d. CPU interrupt.
Answers
Answer:
B. - Direct Memory Access (DMA)
Explanation:
...
Direct Memory Access (DMA) is the technique to free up the CPU by allowing device controllers to independently transfer data between the device and main memory. Thus, option B is correct.
What is Direct Memory Access?Direct memory access is a computer system feature that allows some hardware subsystems to access main system memory without relying on the central processor unit.
Direct memory access (DMA) is the method of transmitting data without using the CPU. It is frequently used to transport data to and from input/output devices. To manage the transfer, a second DMA controller is necessary.
DMA is a mechanism that allows an input/output (I/O) device to transmit or receive data directly to or from main memory, bypassing the CPU to speed up memory operations. A chip known as a DMA controller manages the process (DMAC).
Therefore, option B is correct.

Explanation:
Both CSS (Cascading Style Sheets) and HTML (Hypertext Markup Language) have online documentation. CSS and HTML are separate languages with different purposes. HTML is used for structuring and presenting content on the web, while CSS is used for styling and formatting the appearance of that content.
Both languages have their own specifications and documentation available online. HTML documentation provides information about the various elements, attributes, and their usage, while CSS documentation covers properties, selectors, and how to apply styles to HTML elements.
Therefore, it is incorrect to say that only CSS has online documentation. Both CSS and HTML have extensive documentation available for reference.

John Doe, the Netcare Hospital's IT director, is in charge of network management. He has asked
for your assistance in developing a network solution that will meet the needs of the hospital. The
hospital is expanding, and the management of the hospital has made funds available for network
upgrades. The medical staff would like to be able to access medical systems from any of the
patient rooms using laptop computers. Access to patient medical records, x-rays, prescriptions,
and recent patient information should be available to doctors and nurses. John purchased new
servers for the data center and installed them. The wireless LAN (WLAN) has about 30 laptops,
with another 15 due in six months. The servers must be highly available. The hospital's patient
rooms are located on floors 6 through 10. Doctors should be able to roam and connect to the
network from any floor.
According to a radio-frequency report, a single access point located in each communication closet
can reach all of the rooms on each floor. The current network is comprised of ten segments that
connect to a single router that also serves the Internet. Routing Information Protocol Version 1
is used by the router (RIPv1). The new back-end servers are housed in the same segment as those
on floor 1. John mentions that users have complained about slow server access, he would like to see a proposal for upgrading the network with faster switches and providing faster access to the
servers. The proposal should also include secure WLAN access on floors 6–10. Include an IP
addressing scheme that reduces the hospital's reliance on Class C networks. He wishes to reduce
the number of Internet service provider-leased networks (ISP).
Draw a logical diagram of the existing network. (8)
Answers
Because the servers in the back end are situated within the identical segment as those found on the first floor, user response times have drastically declined.

You compared each letter in the correct word to the letter guessed.
Assume the correct word is "world."
Finish the code to compare the guessed letter to the "o" in "world."
Answers
Sure, here's an example code snippet that compares a guessed letter to the "o" in "world":
The Programcorrect_word = "world"
guessed_letter = "a" # Example guessed letter
if guessed_letter == correct_word[1]:
print("The guessed letter matches the 'o' in 'world'")
else:
print("The guessed letter does not match the 'o' in 'world'")
In the above code snippet, the if statement compares the guessed letter (guessed_letter) to the "o" in "world" by checking if it is equal to the character at index 1 in the correct_word string (Python strings are 0-indexed, so index 1 corresponds to the second character in the string, which is "o" in this case).
If the guessed letter matches the "o", the code prints a message saying so; otherwise, it prints a message indicating that the guessed letter does not match the "o". You can modify the value of guessed_letter to test the code with different guessed letters.
