Answer:
Explanation:
The correct answer is option 'B' CAM (Content Addressable Memory).
CAM (Content Addressable Memory):
Content Addressable Memory (CAM) is a type of memory that is capable of determining whether a given datum is contained in one of its addresses. CAM is also known as associative memory or associative storage. It is a special type of memory that enables rapid searching and retrieval of data based on its content rather than its memory address.
Working of CAM:
CAM works by comparing the input data with the data stored in its memory and providing an output indicating whether there is a match or not. It searches the entire memory in parallel rather than sequentially, which makes it faster than other memory types.
Advantages of CAM:
1. Fast Search: CAM allows for fast searching and retrieval of data based on its content, making it suitable for applications that require quick access to large databases.
2. Parallel Comparison: CAM performs parallel comparison of the input data with the stored data, enabling simultaneous searching of multiple addresses.
3. Single-Cycle Search: CAM can search for a given datum in a single cycle, which significantly reduces the access time compared to other memory types.
Applications of CAM:
1. Network Routers: CAM is commonly used in network routers for routing table lookups. It allows for fast matching of destination addresses with routing entries.
2. Database Systems: CAM is used in database systems for searching and retrieving data based on its content rather than its memory address.
3. Pattern Matching: CAM is used in pattern matching applications, such as searching for specific patterns in text or image recognition.
Conclusion:
In conclusion, a memory that is capable of determining whether a given datum is contained in one of its addresses is a Content Addressable Memory (CAM). CAM allows for fast searching and retrieval of data based on its content, making it suitable for various applications such as network routers and database systems.
