Managed VS. Unmanaged Switch: Detailed Differences
Managed switches differ significantly from unmanaged switches. Managed switches offer control and flexibility for network administrators, while unmanaged switches enable automatic communication among LAN devices without user intervention. To better understand these differences, let's explore key points.
Configuration
Managed switches offer a high level of control and configuration options. They typically come with a web-based or command-line interface (CLI) allowing network administrators to configure various settings. Managed switches support features like Virtual LANs (VLANs), Quality of Service (QoS) settings, port mirroring, and more.
While unmanaged switches are "plug-and-play." They require no configuration and have no user interface. They operate at a basic level and simply forward data packets from one port to another without any user intervention.
Performance
Managed switches offer performance enhancement through features like SNMP support and port mirroring, enabling network monitoring, metric-based decision-making, and control actions like bandwidth limitation. You may have greater control over how traffic is managed, routed, and prioritized. This can lead to more efficient network performance and reduced congestion.
Unmanaged switches come with built-in QoS mechanisms, which, while static and unchangeable, are sufficient to maintain optimal performance in basic networks. They typically have lower latency because they lack the additional processing overhead required for advanced features and customization.
Cost
Switch prices are primarily determined by the number of ports and the bandwidth of those ports. Switches with more ports and higher bandwidth tend to be more expensive. Therefore, when comparing managed and unmanaged switches, it's essential to consider models from the same manufacturer, with the same line, number of ports, and bandwidth specifications. Typically, managed switches cost approximately twice as much as unmanaged ones, if not more.
Security
Unmanaged switches have basic security and rely on physical measures like lockable port covers to prevent tampering. Managed switches offer more advanced security features, including threat monitoring, data protection, access control lists, encryption, and VLANs for controlled network access.

Manage Switches VS. Router VS. Unmanaged Switches VS. Hubs: What's Distinction?
Besides switches, routers and hubs are both networking devices that allow you to connect multiple devices to a single network. But they perform different roles and offer distinct functionalities. Let's explore them.
What is a router?
A router operates by linking one network to another network through a modem, typically establishing connections between LANs (Local Area Networks) or WANs (Wide Area Networks). Typically situated at the network's gateway, the router arranges and forwards data packets along the network.
What is a hub?
Hubs function much like "extension cables" within a network, transmitting all incoming messages from one port to every connected device. This means that every device on the network receives all messages, regardless of their intended destination. Unfortunately, this broadcast approach results in message collisions, leading to the slowdown of network speed and potential delays in data transmission.
Comparison between switches, routers and hubs
Here's a comparison table listing the key differences between managed switches, routers, unmanaged switches, and hubs:
| Aspect | Managed Switches | Routers | Unmanaged Switches | Hubs |
