Post #7 Tech Topic Connection

    Network architecture is one of the most important topics in information technology (IT). Many topics in this course relate to network architecture. Network architecture is the design and organization of computer networks that describe various methods for transferring data and providing services to host systems. As we know, computer systems progressed from stand-alone systems to communication and processing systems through interconnected computer systems. So, it is related to computer history. The network architecture depends on computer architecture, because computers have hardware components such as processors, memory, and input/output devices, and this knowledge is used for communication between computers in networks and for expanding their capabilities for receiving and processing new data.

    Network architecture is part of the network devices and depends on computer hardware. Knowing the characteristics of routers, switches, servers, and end-user devices helps us understand their functions in data transmission and network reliability. Each device has its own function, such as separating networks (routers), connecting devices in the LAN (switches), etc. The basic hardware components common to all devices are a CPU (computer processor) to execute networking protocols, memory to store the routing table and data buffers, and network interface cards (NICs) to connect to the physical network (e.g., fiber or Ethernet). The network architecture is implemented and managed using various programming languages. The programming languages range from low-level firmware written in C or assembly language to network configuration and automation scripts. High-level programming languages are used for network management and optimization.

    Application software is the part of the network architecture through which users access services. Application software is a program that is designed to perform specific tasks. Like web browsers are used to open websites, enterprise software is used for secure remote connectivity and for many other applications. Many applications use the network to provide their services. So these applications use network resources. Database concepts are closely related to network concepts. Distributed databases and cloud storage also use the network for data replication and synchronization. A good DBMS uses network protocols to maintain data consistency and provide quick responses to users anywhere in the world.

    Network architecture is the field where technology and network management meet. In addition to the concepts we have seen so far (layers, routing, error control), a network architecture student must also have basic knowledge of network management and security. Therefore, the study of layers (OSI or TCP/IP) used in network architectures, routing and error control, firewalls, cryptography, and intrusion detection systems is very important for the design of network architectures. Network architecture, as we have seen many times, is a technical topic with significant management and security components.

    Network architecture is a subject rooted in a multidisciplinary set of ideas from Information Technology and Computer Science. This subject encompasses all historical, technological, and software aspects and is closely related to network security. The subject of networks is fundamental, and it is essential to understand their role in today’s computers. In fact, networks enable communication between entities, data exchange, and most of today’s services.
