The sequencing information that TCP uses to Reassemble packets is contained in the TCP header of the packet.

The TCP header contains several fields, including the sequence number and acknowledgement number, which are used to ensure that packets are received and assembled in the correct order.

When packets arrive out of order, TCP uses the sequence numbers to determine the correct order and reassemble the packets accordingly. In addition to sequencing information, the TCP header also contains other important information such as the source and destination ports, window size, and checksum.

This information is used by TCP to establish and maintain connections, ensure data integrity, and manage congestion control. Overall, the sequencing information contained in the TCP header is critical to ensuring that data is transmitted and received correctly over the internet.

The best choice for storing a significant amount of structured data on a device that needs to be retrieved and modified frequently would be SQLite. So, option B is accurate.

The best choice for storing a significant amount of structured data on a device that needs to be retrieved and modified frequently would be SQLite. SQLite is a self-contained, serverless, and zero-configuration relational database engine that is widely used in mobile and embedded platforms, including Android and iOS. It provides a reliable and efficient way to store structured data on the device, with support for complex queries, transactions, and data integrity features.

Regular file I/O is not the best choice for storing structured data that needs to be frequently retrieved and modified, as it may require manual parsing and serialization/deserialization of data, and may not provide efficient querying or transactional support.

Firebase Real-Time is a cloud-based real-time database service, which can be used for storing data in the cloud and syncing it across multiple devices in real-time. While it can be used for storing structured data, it requires an internet connection and may not be suitable for offline scenarios or when data needs to be stored locally on the device.

Shared preferences is a simple key-value pair storage mechanism provided by Android for storing small amounts of data, such as app preferences or settings. It is not suitable for storing significant amounts of structured data that needs to be frequently retrieved and modified, as it is primarily intended for small and simple data storage.

Anya is likely to allow False Rejection Rate (FRR) to be relatively high because denying access to authorized individuals could have serious consequences in a high-secrecy government installation.

A higher FAR would mean allowing unauthorized individuals to access the installation, which is less tolerable in this context.

Anya, as a cyber-security engineer working on a high-secrecy government installation, would be configuring the bio-metric security system with facial recognition software. In this circumstance, she is likely to allow the False Acceptance Rate (FAR) to be relatively high. This is because a high False Rejection Rate (FRR) would mean denying entry to authorized personnel more frequently, which could cause issues in a high-security environment. A higher FAR would mean allowing unauthorized individuals to access the installation, which is less tolerable in this context. To minimize the risk, Anya would likely aim for low error rates overall but prioritize reducing the FRR to ensure authorized personnel has smooth access.

Each new subnet can host 62 machines (64 addresses minus 2 for the network address and broadcast address).

Given the IP address 192.168.1.0/24, assume each LAN should host the same number of PCs.

Create 4 new subnets.

To create 4 new subnets, you can borrow 2 bits from the subnet mask (24) since [tex]2^2 = 4.[/tex]

The new subnet mask will be /26 (24 + 2).

So, the new subnets will have IP addresses as follows:

Subnet 1: 192.168.1.0/26

Subnet 2: 192.168.1.64/26

Subnet 3: 192.168.1.128/26

Subnet 4: 192.168.1.192/26

Each new subnet can host up to 62 machines since [tex](2)^{32-26} - 2 = 62.[/tex]The reason why 2 is subtracted is that the first address in each subnet is reserved for the network address, and the last address is reserved for the broadcast address.
Given the IP address 192.168.1.0/24, you want to create 4 new subnets.

To do this, you need to borrow 2 bits from the host portion of the address, changing the subnet mask from /24 to /26.
