A computer network's principal role is to facilitate the transfer of digital information between computers. An interconnected network of computer equipment is all that constitutes a computer network. Distributing tasks among different machines is frequent in a computer network. Most networks confront substantial threats from attacks on their resources. This research focuses on computer networks. It is only through the establishment of a computer network that this is made possible at all. Nodes include things like computers, cell phones, servers, and other networking gear. Computer networks enable the Internet, as well as the shared use of application and storage servers, printers, and fax machines. Through the use of computer networks, many jobs can be completed. Systems can be classified as open or closed. If you want to connect to the network, the open system is ready to go. Closed systems, on the other hand, require further authentication to connect to other networks.

The changes in network dynamics demands a routing algorithm that adapts intelligently with the changing requirements and parameters. In this regard, an efficient routing mechanism plays an essential role in supporting such requirements of dynamic and QoS-aware network services. This paper has introduced a self-learning intelligent approach to route selection in the network. A Q-Routing approach is designed based on a reinforcement learning algorithm to provide reliable and stable packet transmission for different network services with minimal delay and low routing overhead. The novelty of the proposed work is that a new customized environment for the network, namely Net-AI-Gym, has been integrated into Open-AI Gym. Besides, the proposed Q-routing with Net-AI-Gym offers optimization in exploring the path to support multi-QoS aware services in the different networking applications. The performance assessment of the NET-AI Gym is carried out with less, medium, and a high number of nodes. Also, the results of the proposed system are compared with the existing rule-based method. The study outcome shows the Net-AI-Gym’s potential that effectively supports the varied scale of nodes in the network. Apart from this, the proposed Q-routing approach outperforms the rule-based routing technique regarding episodes vs. Rewards and path length.
Computer networking is an emerging and fascinating field of study. A computer network allows communication and exchange of information between two or more independent computers and other devices. Computer networking is based on the related discipline of electrical engineering, computer engineering, and computer science. Nodes and Links constitute the basic building blocks of the computer network. An equipment for data communication or equipment of data terminal that connects two or more computers such as modem, router etc. can be exemplified as a network node. Links include wires, cables or free spaces of wireless networks. Working of computer networks relies on a set of defined rules or protocols. The network structure can be composed of various patterns known as network topology. Various networking models are developed that relies on various networking layers made of different protocols. In modern times, the importance of computer networks is remarkable in almost every areas including education, entertainment, business, military, healthcare, insurance, transportation and others. With so much reliance on computer networking, it becomes important to ensure a safe and secure networking system and thus network security system was developed such includes firewall, VPNs, IDS and IPS, etc
Information has become one of the 21st century's most important assets of an organization and efforts to keep information secure have correspondingly become increasingly important. There is no doubt that information assets are under attack. But what makes an information system unsecure? Understanding threats and their source, agent, intent and impact is the very first step to security. Information security is a science discipline, which has extended to include several research directions. The model followed at this thesis consists in addressing security levels at each layer of the Open System Interconnection (OSI) model. The main purpose of this paper is to identify and analyse the most frequent attacks that might happen in Data link, Network and Application layers and propose the right defence methods and techniques. To better fulfil this analysis there is also an implementation.
