Types of switch KVM

A switch KVM (which stands for Keyboard, Video, and Mouse) is a hardware device that allows the user to control multiple computers with a single set of input devices. A KVM switch comes in several forms, including the standard KVM switch, which allows one to use the same keyboard, monitor, and mouse for multiple computers. It can be physical or virtual, depending on the system's structure. A physical KVM switch is a hardware device that allows the user to control multiple computers from a single console of the keyboard, video monitor, and mouse. It can be a rack-mountable device for server rooms or offices with many computers or a small desktop unit for personal use.

On the other hand, a virtual KVM switch is a software application that provides similar functionality as a physical KVM switch but operates in a virtualized environment. It allows the user to switch between different virtual machines or servers using the same keyboard, video monitor, and mouse.

Depending on how the switch works, it can be divided into two types. KVM switches can be categorized into two types, based on their operating mechanisms: the electronic KVM switch and the mechanical KVM switch. The electronic KVM switch is equipped with a microprocessor that processes the input signals and transmits them to the target computer. It uses a technology called USB hub-based emulated to perform this function. On the other hand, the mechanical KVM switch is a basic and straightforward device that uses a physical switch to change the connection between the computer and the keyboard, monitor, and mouse. It is a passive device that does not require any power source to operate.

• Secure KVM Switch:

Secure KVM switches provide additional security features to protect sensitive information. They typically offer encryption of keyboard, video, and mouse signals to prevent unauthorized access or data interception. Some secure KVM switches also include features like tamper-proof hardware, strong authentication mechanisms, and audit logging to ensure compliance with security standards and regulations. These switches are commonly used in government, military, and other high-security environments where protecting data is critical.

• Desktop KVM Switch:

Desktop KVM switches are compact devices designed for use in small office or home office environments. They allow a single keyboard, monitor, and mouse to control two or four computers. Desktop KVM switches are typically available in two-port and four-port configurations and connect to computers via USB and VGA or HDMI cables. These switches are ideal for users who need to switch between multiple computers but have limited desk space.

• Rackmount KVM Switch:

Rackmount KVM switches are designed to be installed in server racks or data centers. They allow system administrators to manage multiple servers or network devices from a single console. Rackmount KVM switches are available in various port configurations, ranging from 8 to 64 ports or more, to support large-scale server environments. They typically include features like hotkey switching, on-screen display, and remote access via IP or serial connections. Rackmount KVM switches help streamline server management tasks, saving space and reducing cable clutter in server rooms.

Function and feature

Switch KVMs have different features that make them suitable for different purposes. Here are some of the features:

• Number of Ports

A port is a place where a cable is connected to the switch. Some KVM switches have up to 64 ports, while others have as little as two. The number of ports is important because it determines how many devices can be connected to the switch. When buying a switch KVM, it is important to know the number of devices to be connected. If there are only two devices, a KVM switch with two ports is suitable. If there are many devices, a KVM switch with many ports is better.

• USB and PS/2 Support

Most KVM switches come with USB and PS/2 support. Some modern switches support other connections like HDMI. USB connections are faster and can connect to a wide range of devices. PS/2 connectors are older and can only connect to older computers.

• Hotkey and Push-Button Switching

Most KVM switches have hotkey and push-button switching. To switch between computers, the user can press a combination of keys or buttons. Some KVM switches have an on-screen display. The display shows the user the computer that is being worked on. Hotkey and push-button switching are fast and efficient.

• Auto-Scan and Auto-Switching

Auto-scan and auto-switching features are useful in a KVM switch. Auto-scan allows a user to switch between computers automatically. The switch can change between computers after a certain period. Auto-switching allows the KVM switch to select the active computer. If a computer is turned off, the switch will automatically connect to the next computer. These features allow work to continue uninterrupted.

• Maximum Resolution Support

The maximum resolution support is the highest resolution that a KVM switch can support. Most KVM switches can support 1920x1080 or 3840x2160 resolutions. However, some professional switches can support up to 4096x2160 resolutions.

• Additional Features

Some KVM switches have additional features. For example, some switches allow a user to connect to multiple monitors. Some KVM switches allow a user to work on multiple computers at the same time. Some KVM switches have a built-in USB hub, allowing a user to connect other USB devices.
