Computer network structure and architecture

In Computer Network ,there are various ways through which different components are connected to one another. Network Topology is the way that defines the structure, and how these components are connected to each other. Types of Network Topology The arrangement of a network that comprises nodes and connecting lines via sender and receiver is referred to as Network Topology. The various network topologies are: Mesh Topology Figure 1: Every device is connected to another via dedicated channels. These channels are known as links. • Suppose, the N number of devices are connected with each other in a mesh topology, the total number of ports that are required by each device is N-1. In Figure 1, there are 5 devices connected to each other, hence the total number of ports required by each device is 4. The total number of ports required = N * (N-1). • Suppose, N number of devices are connected with each other in a mesh topology, then the total number of dedicated links required to connect them is NC 2 i.e. N(N-1)/2. In Figure 1, there are 5 devices connected to each other, hence the total number of links required is 5*4/2 = 10. Advantages of Mesh Topology • Communication is very fast between the nodes. • Mesh Topology is robust. • The fault is diagnosed easily. Data is reliable because data is transferred among the devices through dedicated channels or links. • Provides security and privacy. Drawbacks of Mesh Topology • Installation and configuration are difficult. • The cost of cab...

Network topology is used to describe the physical and logical structure of a network. It maps the way different nodes on a network--including switches and routers--are placed and interconnected, as well as how data flows. Diagramming the locations of endpoints and service requirements helps determine the best placement for each node to optimize traffic flows. • • What does a network topology do? A well-planned network topology enhances the user experience and helps administrators maximize performance while fulfilling business needs. When the right topology is chosen for a business's needs, it is easier to locate faults, troubleshoot and fix problems, and share resources across networks. With a properly managed network topology, a business can improve the efficiency of its data transfer. Better efficiency, in turn, helps reduce costs for maintenance and operations. What kinds of network topologies are there? Network topologies are generally arranged in two ways: Physical (or underlay): This maps the actual connections in a network, such as wires and cables and the placement of various components. Logical (or overlay): This shows how data flows within a network and from one device to another, regardless of the physical connections among devices. While the logical network uses the physical connections for data transfer, the actual flow of data is defined by the logic not the physical connections. How do I diagram a network topology? Network topologies can be sketched out on p...

Computer artificial intelligence's impact on society is widely debated. Many argue that AI improves the quality of everyday life by doing routine and even complicated tasks better than humans can, making life simpler, safer, and more efficient. Others argue AI poses dangerous privacy risks, exacerbates racism by standardizing people, and costs workers their jobs leading to greater unemployment. For more on the debate over artificial intelligence, visit computer, device for processing, storing, and displaying information. Computer once meant a person who did computations, but now the term almost universally refers to automated electronic see Computing basics The first computers were used primarily for numerical calculations. However, as any information can be numerically encoded, people soon realized that computers are capable of general-purpose Computers also have limitations, some of which are theoretical. For example, there are undecidable propositions whose truth cannot be determined within a given set of rules, such as the logical structure of a computer. Because no universal See Computers and Operating Systems see One advantage of analog computation is that it may be relatively simple to design and build an analog computer to solve a single problem. Another advantage is that analog computers can frequently represent and solve a problem in “real time”; that is, the computation proceeds at the same rate as the system being modeled by it. Their main disadvantages are tha...

Why is network design important? As networks become mission-critical for business functions, design decisions made by IT professionals can have far-reaching implications. A network with a well-planned design will perform better. It will be more secure and resilient and easier to troubleshoot, and it will scale easily and adapt to future technologies. Is network design the same as network topology? Whereas network design encompasses business processes and results, network topology refers to the design as viewed through network diagrams, often called topology maps. Ring, chain, tree, and mesh are a few types of network topology. What is the process for creating network design? A network diagram is typically the workhorse of the design process. It provides a visual representation of the network and integrates information such as physical connections; quantity, type, and location of all devices and endpoints; IP addressing; and security processes and architecture. Network design software can help by creating a site or office plan to map physical connections. When building a network from scratch, the first step is to assemble a list of all the assets, endpoints, users, devices, LANs, and other network elements. IT teams enter this information in the network design application to create the first iteration of a network diagram. When designing for existing network environments, the process integrates existing infrastructure that must be maintained or kept running during productio...

A company’s IT network is the backbone of its business as it connects all its computers and related devices together, allowing staff to work more efficiently across the organization. With something so mission-critical it’s crucial it is designed and set up properly. If you’re wondering how to design a network, this blog aims to help you understand the basics of good network infrastructure design. What is network design? Network design is the planning phase a company’s IT infrastructure must go through before it is implemented. It involves evaluating and understanding how all the elements of the network link together (from routers, switches, and servers to desktops, laptops, and printers) and how they can be made to run as efficiently as possible. A well-designed network can bring increased operational efficiency. Network design is a task that is usually performed by network designers, IT administrators, and other related employees. To help with the physical implementation process, the network design should be drawn out as a There are a number of details your network infrastructure design should show, these include: • A clear map of the network • The structure and layout of the cabling required • The quantity, type and location of all devices on the network • Your IP addressing structure • Details of your network security architecture and processes Network design best practices To ensure you deliver the best network design possible, here are five network design best practic...

Many universities across the world offer degrees that teach students the basics of computer science theory and the applications of computer science, the study of Computer science is considered as part of a family of five separate yet interrelated disciplines: computer engineering, computer science, The major subfields of computer science include the traditional study of Development of computer science Theoretical work on computability, which began in the 1930s, provided the needed In the 1950s, most computer users worked either in scientific research labs or in large corporations. The former X). Another program, known as an Other Later in the 1950s, assembly language was found to be so cumbersome that the development of high-level languages (closer to natural languages) began to support easier, faster programming. Increasing use of computers in the early 1960s provided the The 1970s and ’80s saw the emergence of powerful Closely related to this field is the design and analysis of systems that interact directly with users who are carrying out various computational tasks. These systems came into wide use during the 1980s and ’90s, when line-edited interactions with users were replaced by The field of computer architecture and organization has also evolved dramatically since the first stored-program computers were developed in the 1950s. So called time-sharing systems emerged in the 1960s to allow several users to run programs at the same time from different terminals that we...
