What is network architecture components? Have you ever pondered the process through which a specific app is developed? How did it operate, as well as the kinds of components being utilized?
Web and mobile developers or other high-level programmers have implemented many different computer architectures throughout the years. A network’s structural and logical design is referred to as network architecture. It comprises transmission medium, hardware devices, physical connections, software, wireless networks, and protocols.
It provides a comprehensive summary of the entire network, which companies can leverage to build local area networks (LANs), wide area networks (WANs), and other specialized communication tunnels. In this part of the guide, you will learn how a network architecture works ‘behind the scenes’ by breaking it down into its components.
An Overview of Network Architecture
Depending on the scope and function of the network, several perspectives on the network’s architecture may be appropriate. When talking about types of networks—a WAN is a collection of networks spread out over a wide area, whereas a LAN is a network that connects computers in a small geographic region. Therefore, a wide area network structure will differ from a small business local area network.
Implementing a well-thought-out network architecture can either improve or detract from the system’s overall performance. Selecting a transmission medium or equipment unsuitable for the anticipated server load in a network, for instance, can slow down various areas of the network.
Adding a layer of security to the network architecture is becoming increasingly important as more consumer devices connect. In addition, present-day network topologies allow for sophisticated user authentication and permission.
The Open Systems Interconnection (OSI) approach is the foundation of most modern network designs. At this point, we can observe the partitioning of network responsibilities into seven distinct logical layers, progressing from the most tangible to the most conceptual levels possible. The lowest is the Physical Layer, in charge of the actual hardware that makes the network possible.
In contrast, the topmost Application Layer handles application programming interfaces (APIs) that enable instant messaging and file transfer tasks. The OSI model simplifies network troubleshooting by isolating issues at their respective layers.
Now, the Key Components of Network Architecture Components
The design of the architecture of a network is primarily concerned with improving its fundamental building blocks. These include the following four essential components:
Hardware
The devices that form any network’s basis are collectively referred to as the “hardware,” a generic term. User devices such as laptops, personal digital assistants (PDAs), mobile phones, routers, servers, and gateways are examples of these. Establishing an effective and efficient method for transferring data from one hardware device to another is the primary goal of any network architecture.
Transmission Media
The term “transmission media” refers to all the physical connections between the various network (hardware) devices. The different transmission mediums’ properties have unique features that govern the maximum data transfer speed from one endpoint to another. These can operate via:
- Wired or Guided Media: This refers to the physical wires or cables used to make network connections, such as coaxial or fibre optics and twisted pair cables.
- Wireless or Unguided Media: It uses the characteristics of microwave or radio transmissions to function; common examples are Wi-Fi and cellular.
Protocols
The terms “protocol” and “rules” are often used interchangeably in computer networking. The language of this standard protocol is used for communication between the various machines connected to a network. If these protocols were not in place, your iPhone would have difficulty accessing a web page that is necessarily stored on a Linux server.
The characteristics of the data themselves determine the kind of network protocol that must be used. File Transfer Protocol (FTP) transfers and receives files to and from a server. On the other hand, Transmission Control Protocol/Internet Protocol (TCP/IP) is used to connect to the internet. Similarly, the Ethernet protocol connects one computing device to another.
Topology
The topology of a network outlines how its components are connected and bring the network’s structure into focus. This is significant because factors such as the distance between communicating devices can impact data transfer speed, affecting the network’s performance.
There are a few different topologies, and each has advantages and disadvantages. In the case of a star topology, all network devices are linked to a centralized hub. This layout is simple for any device to establish a connection to the network. However, the entire network may become inoperable in milliseconds if the central hub becomes corrupted.
Another type is bus topology, which connects along a single path or linearly. The bus is analogous to a highway that moves data in a direction from one endpoint to another. This topology is simple, inexpensive, and could be better for small-scale networks. Most notably, the performance of this topology may suffer as more devices are added to the network.
Most modern network architectures use a hybrid approach, combining and blending different topologies to compensate for each topology’s shortcomings.
Final Thoughts
Although protocols and software are necessary, quality hardware is essential to any successful network. Regardless of the architecture, you decide to go with, the networks also need to be dynamic, adaptable, and in step with the requirements of the business.
The time-honored and labor-intensive methods traditionally used to manage computer networks are untenable. It is vital to take new paths which require fundamental changes in the architectural design of network systems. This was all about network architecture components.
