Solution
Introduction
This report is aim to create a network design for the hospital by using the cisco packet tracer. They want to implement a secure network into their hospital and so they want to first create demo in the cisco tool. Added to the physical arrangement, the scenario describes the staffing organisation, which consists of four management staff members, three finance officers, five nurses, as well as three physicians. University Assignment Help, The necessities for communication are listed, with management and finance executives having their own telephone and doctors and nurses on Levels 2 and 3 sharing four phones per level. A customized strategy for networking solutions must be adopted because of the levels of complexity this intricate configuration brings. This will be help in understanding the performance of the network.
Network subnets
A Class C private IP address range is used into the network and it is represented by the IP address 192.168.10.1/24, where the "/24" stands for the subnet mask [5]. Eight bits are left behind in a "/24" subnet for host addresses within the network, with the first 24 bits being used for the network component. It's possible to dissect an IP address to find the network and host portions:
Subnet Mask: /24 IP Address: 192.168.10.1
Decomposing the IP address into binary code:
IP Address: 11000000.10101000.00001010.00000001
Subnet Mask: 11111111.11111111.11111111.00000000

Network Topology:
Combining two or more distinct network topologies results in a hybrid network topology. It is intended to make advantage of the benefits of different topologies in order to meet expected operating or organizational needs. Often, the objective is to establish a more adaptable and resilient network that overcomes the shortcomings of specific topologies. An outline of the essential elements as well as traits of a hybrid network topology is offered.
A hybrid network architecture provides a calculated approach to creating networks that meet certain organizations' demands. It balances many topologies, utilizing each one's advantages to build a more adaptable and durable network architecture [4].

Security measures:
A crucial component of information technology management is security of networks, which guarantees the confidentiality, availability, and authenticity of data.
Firewall: With the help of pre-established security rules, firewalls closely track and control all incoming and outgoing network traffic, serving as a barrier between trusted internal networks as well as untrusted external networks. Although software firewalls can be put on devices themselves, hardware firewalls are typically implemented at the network perimeter.
ACLs, or access control lists, are used to regulate traffic on networks by setting rules that allow or forbid on protocols, ports, the origin and destination IP addresses, as well as other factors. Configured to manage traffic at different network nodes on routers, switches, as well as firewalls. Combining these security measures leads to a layered defines approach that increases the difficulty of network penetration by attackers. Another essential element of a strong network security posture is conducting regular security assessments as well as keeping up with new threats.

OSI models:
A theoretical framework known as the Open Systems Interconnection (OSI) model divides the inner workings of a computer or system of communications into seven abstract layers, every one of whose functions serves a distinct purpose in promoting communication among devices. The structure of the model goes via the following layers: data link, network, transport, session, presentation, as well as application. The physical layer deals with equipment connections as well as electrical impulses [2].
The sending and receiving of raw data bits via physical media is the responsibility of the physical layer, which is the most basic.
By managing segmentation, flow management, as well as error recovery, the transport layer guarantees end-to-end communication.
The application layer, which is the highest layer, acts as a direct conduit between users as well as the network, giving apps access to network services. The OSI model's layers cooperate with one another while yet functioning independently to allow seamless transmission of information across networks [1].
