Consider the following IP address that uses CIDR notation: 172.17.8.5/22
Which subnet mask corresponds to the CIDR notation used in this address?

255.255.255.0

255.0.0.0

255.255.252.0

Answers

The correct subnet mask that corresponds to the CIDR notation used in the IP address 172.17.8.5/22 is 255.255.252.0.

The CIDR notation used in the given IP address 172.17.8.5/22 represents a network address and a prefix length. The prefix length is specified as /22 which means that the first 22 bits of the IP address represent the network portion of the address and the remaining bits represent the host portion of the address.

To determine the corresponding subnet mask for the CIDR notation used in this address, we need to convert the prefix length to a binary subnet mask. A /22 prefix length requires 22 bits to be set to 1 in the subnet mask, starting from the leftmost bit.

In binary, the subnet mask for a /22 prefix length would be 11111111 11111111 11111100 00000000. Converting this binary subnet mask to decimal notation gives us 255.255.252.0.

Therefore, the correct subnet mask that corresponds to the CIDR notation used in the IP address 172.17.8.5/22 is 255.255.252.0. This subnet mask identifies the network address as 172.17.8.0 and allows for up to 1022 hosts to be connected to the network.

briefly explain how unstructured p2p networks are organized. why is it sometimes difficult to search for data/files on unstructured p2p networks? g

Answers

Unstructured P2P networks are organized in a decentralized manner where each node can communicate directly with any other node. There is no central server that manages the network, and there are no fixed rules or structures for how data is organized or shared. This means that any node can act as both a client and a server, and data can be shared between nodes in a completely distributed manner.

How the files are searched in Unstructured P2P?

This lack of structure also makes it difficult to search for data or files on unstructured P2P networks. There is no central index or directory of available resources, and nodes must rely on broadcasting search queries to other nodes in the network. This can lead to slow and inefficient search results, and it can also be challenging to ensure that search results are accurate and relevant. Additionally, unstructured P2P networks are often used for sharing copyrighted material illegally, which can further complicate the search process.  The search queries are sent to neighboring peers, who in turn forward the query to their neighbors, and so on. This process can lead to high network traffic, longer search times, and an increased likelihood of not finding the desired file, as the search may not reach all parts of the network.

in tiva c, each interrupt is associated with an interrupt priority number. interrupt a has a priority number of 5, and interrupt b has a priority number of 3. if the two interrupts happen simultaneously (exactly at the same cpu clock cycle), what will happen? explain briefly.

Answers

If interrupts A and B occur simultaneously on a Tiva C microcontroller, the interrupt with the higher priority (in this case, interrupt A with a priority of 5) will be serviced first by the CPU.

Interrupt priority levels are used to determine the order in which interrupts are serviced by the CPU. When multiple interrupts are pending, the CPU uses the priority level of each interrupt to determine which one to service first. Interrupts with higher priority levels are serviced before interrupts with lower priority levels.

In the case of interrupts A and B occurring simultaneously, the CPU will first service interrupt A because it has a higher priority level of 5. Once interrupt A has been serviced, the CPU will then move on to service interrupt B with a priority level of 3.

It is important to carefully consider the priority levels assigned to interrupts to ensure that critical interrupts are serviced promptly. If lower-priority interrupts are not serviced quickly enough, they may cause delays in servicing higher-priority interrupts, which can lead to unpredictable behavior and potential system failures.
