Subnet A =125, subnetB=0,Subnet C= 13 are the three ip addresses that needs to be assigned to the host respectively
What is a subnet?
A subnet, also known as a subnetwork, is a segmented section of a larger network. Subnets are a logical division of an IP network into multiple, smaller network segments. The Internet Protocol (IP) is a protocol used to send data from one computer to another over the internet.
For example:
A subnet is a network subnetwork that is classified as A, B, or C. For example, 172.16.0.0/16 is a class B network. This network is quite large; it begins with 172.16.A class C network would have a subnet mask of 255.255.255.0, indicating that the network uses 24 bits. This is denoted by a /24 after the IP address in CIDR notation.

what basic database design strategies exist? describe top down and bottom up, centralized and decentralized design). explain how such strategies executed? and what are the consideration to know which strategy to choose?
Top-down and bottom-up are the two main methods used in database design.
Define the term database design.
Data organizing using a database model is known as database design. The designer decides what information must be kept on file and how the data elements interact. Now that they have this knowledge, they can start to match the data to the database model.
The data is managed in accordance with a database management system. Tables, indexes, views, constraints, triggers, stored procedures, and other database-specific components required to store, retrieve, and remove persistent objects must all be included in the thorough database architecture defined by the database designer.
Answer continued:
The first step in top-down design is to define each entity type's attributes and to identify the many entity types that exist. In other words, top-down design first defines the necessary data sets, and only then does it describe the data items for each of those data sets.
Bottom-up design first identifies the necessary properties, then groups them to create entities.
When the system's data component contains a sizable number of entities and intricate relationships on which highly sophisticated actions are carried out, centralized architecture may be applied.
The database design task is broken down into a number of modules inside the decentralized design framework. Following the establishment of the design requirements, the lead designer distributes design subsets or modules to design groups within the team.

What is a lossy compression?In Computer technology, a lossy compression is sometimes referred to as irreversible compression and it can be defined as a type of data encoding (data compression algorithm) in which the data in a file is removed by using inexact approximations, in order to reduce the amount of size of a file after decompression.
What is RLE?In Computer technology, RLE is an abbreviation for run length encoding and it can be defined as a type of lossless compression technique in which all of the sequences that are used for displaying redundant data are stored as a single data value.
In this context, we can reasonably infer and logically deduce that run length encoding (RLE) would be most appropriate in this scenario.
