List - I List - II A. Ethernet I. Uses token passing and deterministic access B. Token ring II. Uses CSMA/CD for medium access C. Wi-Fi (802.11) III. Uses CSMA/CA to avoid collision D. Bluetooth IV. IEEE 802.15.1
Choose the correct answer from the options given below:
Match List - I with List - II.
| List - I | List - II | ||
|---|---|---|---|
| A. | Ethernet | I. | Uses token passing and deterministic access |
| B. | Token ring | II. | Uses CSMA/CD for medium access |
| C. | Wi-Fi (802.11) | III. | Uses CSMA/CA to avoid collision |
| D. | Bluetooth | IV. | IEEE 802.15.1 |
Choose the correct answer from the options given below:
Show Hint
Wires detect (CSMA/CD). Wireless avoids (CSMA/CA). Rings pass tokens. Bluetooth is 15.1.

The Correct Option is A
Solution and Explanation
We match various networking technologies with their standard protocols and access methods.
1. Ethernet (A-II):
Standard wired LANs (IEEE 802.3) use CSMA/CD (Carrier Sense Multiple Access with Collision Detection) to manage access to the physical medium.
2. Token Ring (B-I):
A legacy network type where a physical or logical "token" is passed between nodes. Only the node holding the token can transmit, making it a deterministic access method.
3. Wi-Fi (C-III):
Wireless networks (IEEE 802.11) cannot detect collisions easily (hidden terminal problem), so they use CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance).
4. Bluetooth (D-IV):
Bluetooth is a Personal Area Network (PAN) technology standardized under IEEE 802.15.1.

- Choose the correct answer from the options given below:
(A). RAID 3 requires only a single redundant disk.
(B) In RAID 4 scheme, two different parity calculations are carried out and stored in separate blocks on different disks.
(C) RAID 5 distributes the parity strips across all disks.
(D) In RAID 2, the number of redundant disks are proportional to the log of the number of data disks. - In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.
- In a two-level memory hierarchy, the access time of the cache memory is 12 nsec and the access time of the main memory is 1.5 msec. The hit ratio is 0.98. What is the average access time of the two-level memory system?
- Match List I with List II.
List I List II A. Supervisor mode I. Entered when the processor encounters a software interrupt instruction B. Abort Mode II. Entered in response to memory fault C. Fast Interrupt Mode III. Entered whenever the processor receives an interrupt signal from a designated fast interrupt source D. Interrupt Mode IV. Entered whenever the processor receives an interrupt signal from any other source - Deallocation of stack of thread and register contexts will take place.
