Metoda yang gunakan untuk mendeteksi media, apakah sedang mengirim sinyal atau tidak, sehingga mencegah terjadinya kekacauan dalam penggunaan medium pada jaringan wireless adalah :
- A.
CSMA/ CD
- B.
CSMA/ CA
- C.
MAC
- D.
LLC
Correct Answer
B. CSMA/ CAExplanation
CSMA/CA stands for Carrier Sense Multiple Access with Collision Avoidance. It is a method used to detect whether the wireless medium is currently transmitting a signal or not, in order to prevent chaos in the use of the medium. This method helps to avoid collisions between data packets by implementing a virtual carrier sensing mechanism. It requires stations to first listen to the medium and wait for a clear channel before transmitting their data. This helps to ensure that only one station transmits at a time, reducing the chances of collisions and improving the overall efficiency of the wireless network.Rate this question:

- D.
Proses framing membagi aliran data menjadi beberapa grup, dengan cara memasukkan informasi kontrol hanya pada header.
Correct Answer
A. Proses framing membagi aliran data menjadi beberapa grup, dengan cara memasukkan informasi kontrol pada header dan trailer sebagai nilai di field yang berbeda.Explanation
The correct answer states that the process of framing divides the data stream into several groups by inserting control information in the header and trailer as values in different fields. This means that the data is divided into smaller segments or frames, with each frame containing control information in the header and trailer. This helps in organizing and managing the data transmission process effectively.Rate this question:
