What are the hardware components of a business network?

NetworkTigers discusses essential hardware components of a business network.

The backbone of a successful business is its network infrastructure. These systems rely on hardware components to ensure seamless communication, data storage, and security. We will dissect the various hardware components of a business network, shedding light on their functions and types.

What is network hardware?

Network hardware comprises a diverse range of devices and components designed to facilitate the transfer, processing, and protection of data in networks, both small and expansive.

Network hardware ensures data flows smoothly, reducing bottlenecks and optimizing network operations. Hardware components protect against unauthorized access and potential threats, safeguarding sensitive data.

As technology advances, businesses and individuals must continually invest in the right hardware components to support their network needs, ensuring their networks remain efficient and secure.

Key components of network hardware

Hardware components ensure information flows seamlessly and securely. Here are the essential components every business network should have:


Servers keep information flowing and applications running within a business network. There are three different types of servers:

  • File servers: These servers are dedicated to storing and managing files and documents. They ensure centralized and secure access to shared resources, fostering efficient collaboration. To perform effectively, file servers require high-capacity hard drives and redundant storage systems.
  • Web servers: These servers respond to client requests from web browsers by delivering web content, including HTML files, images, and multimedia. They are the backbone of websites and web applications. Web servers require powerful processors, sufficient RAM, and high-speed data access.
  • Application servers: These servers host and manage software applications, enabling them to run efficiently and securely. They facilitate communication between the application and database servers.   Application servers require substantial processing power and RAM to support application operations.


Switches connect various network devices, directing traffic efficiently and enhancing the overall performance of a network. There are two types of switches:

  • Managed switches: These switches offer advanced control and configuration options. They allow network administrators to adjust settings, monitor network traffic, and provide security features. They are often used in larger networks, where fine-tuned control and performance optimization are critical. Managed switches support features like VLAN management and Quality of Service (QoS).
  • Unmanaged switches: These switches are simple, plug-and-play devices with no user-configurable settings. They are designed for basic connectivity and offer no control over network operations. Unmanaged switches are suitable for smaller networks or environments where simplicity and ease of use are preferred.


Routers connect disparate network segments, ensuring data reaches its intended destination swiftly and securely. Here are the hardware components of routers:

  • Ports: Ports are physical connectors on routers that link to other network devices. Common port types include Ethernet ports, WAN (Wide Area Network) ports, and USB ports. Ports are the entry and exit points for data into and out of the router. WAN ports connect to external networks, while Ethernet ports link to local devices.
  • Routing tables: Routing tables are databases within routers that contain information about network routes, IP addresses, and next-hop destinations. They enable routers to make intelligent decisions about how to forward data packets. They are crucial in determining the most efficient path for data traversal.
  • Security features: Routers often include hardware components that support security features. These include hardware firewalls, intrusion detection and prevention systems (IDPS), and Virtual Private Network (VPN) acceleration. Hardware firewalls, for instance, act as barriers against unauthorized access, and VPN acceleration improves secure remote access.


Firewalls act as a barrier between trusted internal networks and untrusted external networks, ensuring that only legitimate and safe data traverses the network.

Different types of firewalls include:

  • Hardware firewalls: These firewalls serve as the first line of defense against network threats. They are placed at the network perimeter, between the internal network and the external world. Hardware firewalls protect entire networks by filtering traffic before it reaches individual devices. They often come with multiple network interfaces and robust security features.
  • Software firewalls: These firewalls are applications or programs that run on individual devices. They are designed to filter traffic at the device level, allowing users to define specific rules for that device. Software firewalls are ideal for personal devices or scenarios where specific application control is required.

Network Attached Storage (NAS)

Network Attached Storage (NAS) devices offer seamless and centralized storage solutions for businesses of all sizes. These devices connect directly to a network, providing a dedicated location for data storage and retrieval. 

They function as file servers, allowing multiple users and devices to access, manage, and store data on a shared storage pool. This centralized approach simplifies data management and ensures data is readily available to authorized users.

Here are the hardware features of NAS devices:

  • Hard drives: NAS devices are equipped with hard drives, the primary storage media. The number and capacity of hard drives can vary, with some NAS units supporting multiple drives. Hard drives determine the storage capacity of NAS devices.
  • RAID configurations: Redundant Array of Independent Disks (RAID) configurations combine multiple hard drives to improve data redundancy and performance. RAID configurations enhance performance and data protection. 

For example, RAID 1 mirrors data on two drives, ensuring data redundancy, while RAID 5 strips data across multiple drives, offering both redundancy and increased storage capacity.

Invest in the right hardware components

Hardware components strengthen network security by addressing vulnerabilities. They also ensure data flows uninterrupted and efficiency is unparalleled. Select the right components to create a robust and efficient network infrastructure.
