A Research Paper on Basic of Computer Network

Abstract

Abstract: Computer networks facilitate the interconnection of systems for the purpose of exchanging digital information. Essentially, they comprise a collection of devices linked together through various connections. Distributed processing is employed in computer networks, wherein tasks are divided among multiple computers. However, one of the most pressing challenges faced by networks is the threat of resource attacks.This research paper delves into the fundamental concepts of computer networks, which are essentially a collection of devices interconnected via links. These devices, or nodes, encompass a variety of entities ranging from personal computers and phones to servers and networking hardware. Computer networks enable various applications to access resources such as the World Wide Web, shared application and storage servers, printers, fax machines, as well as email and instant messaging applications. They play a pivotal role in facilitating information sharing across diverse tasks.Computer networks can be classified into two types: open systems and closed systems. Open systems are easily connected to networks and are primed for communication. Conversely, closed systems require proper authentication and are not as readily connected to other networks..
