which network topology uses multiple acess points to link a series of devices that speak to each other to form network connection across a large area
The network topology that uses multiple access points to link a series of devices across a large area is called a "Mesh Network."
In a mesh network, each device acts as a node and can communicate directly with neighboring devices. This allows for decentralized communication and provides redundancy and fault tolerance since multiple paths are available for data transmission. If one device or access point fails, the network can still function by rerouting the data through other available paths. Mesh networks are commonly used in scenarios where a reliable and extensive network coverage is required, such as in smart home systems, industrial settings, and large-scale outdoor deployments.

the advantages of asymmetric encryption include all the following except:
Asymmetric encryption offers several advantages, including enhanced security, key distribution convenience, and digital signatures. However, it does not provide the advantage of faster encryption and decryption compared to symmetric encryption methods.
Why doesn't asymmetric encryption offer faster encryption and decryption compared to symmetric encryption methods?Asymmetric encryption, also known as public-key encryption, involves the use of a pair of keys: a public key for encryption and a private key for decryption. This approach provides improved security as the private key remains secret. Additionally, asymmetric encryption enables convenient key distribution since anyone can use the public key to encrypt messages intended for the owner of the corresponding private key. It also facilitates digital signatures, allowing the recipient to verify the authenticity and integrity of the message.
However, one disadvantage of asymmetric encryption is its relatively slower encryption and decryption process compared to symmetric encryption methods. This is because asymmetric encryption algorithms are more computationally intensive and require larger key sizes to achieve the same level of security as symmetric encryption. As a result, asymmetric encryption is typically used for securing key exchanges and digital signatures rather than encrypting large amounts of data.

given an ordered array with 15 elements, how many elements must be visited in the worst case of binary search? group of answer choices 3 4 2 8
In the worst case of binary search for an ordered array with 15 elements, 4 elements must be visited.
Binary search is a searching algorithm that works on the principle of divide and conquer. It starts by comparing the middle element of the array with the target value and then recursively searches in either the left or right subarray based on the comparison result. In the worst case, the target element is not found in the array and the search continues until the subarray has no elements left. For an ordered array with 15 elements, the binary search algorithm will take at most 4 comparisons to find the target element or determine that it is not in the array.
