What Is iSCSI? iSCSI (Internet Small Computer System Interface) is a protocol that enables SCSI commands and data to be transported over TCP/IP networks, allowing remote storage devices to be accessed as if they were locally attached. It encapsulates SCSI commands and data into TCP/IP packets for transmission over IP networks. How iSCSI Works The iSCSI architecture consists of two main components: the initiator and the target. The initiator is typically a server or host that initiates SCSI commands and data requests, while the target is a storage device or server that responds to these requests. The initiator and target communicate…

What Is a Pneumatic System? A pneumatic system is a conversion of energy from fluid power (compressed air) to mechanical energy or work force. It utilizes pressurized gas, typically compressed air, to produce mechanical motion. Pneumatic systems are widely used in industrial automation, offering benefits such as affordability, natural cooling, environmental safety, and simplicity. How Does a Pneumatic System Work? Key Components of a Pneumatic System A pneumatic system typically consists of the following components: Advantages of Pneumatic Systems Disadvantages of Pneumatic Systems Comparison: Pneumatic vs Hydraulic Systems Hydraulic systems use incompressible liquids (e.g., oil) as the working medium, while…
Introduction: LiDAR vs Radar – What’s the Difference? LiDAR vs Radar highlights two crucial sensing technologies with distinct strengths. LiDAR offers high-resolution mapping and precision, while Radar excels in long-range detection and weather resilience. Choosing the right technology depends on your application’s needs and conditions. What Is LiDAR? LiDAR is an active remote sensing technology that measures distances by illuminating targets with laser light and analyzing the reflected pulses. The key principles behind LiDAR systems include: What Is Radar? Radar (Radio Detection and Ranging) is a similar technology that uses radio waves instead of light to detect and locate objects.…
Introduction: SAN vs NAS – What’s the Difference? SAN vs NAS highlights two distinct approaches to network storage. NAS offers file-level storage for small to medium-sized setups, while SAN delivers high-speed block-level storage for enterprise environments. Choosing the right option depends on your performance needs and budget. What Is NAS? A NAS (Network Attached Storage) is a file-level storage device connected to a traditional IP network. It operates as a file server, providing shared access to files using protocols like NFS or CIFS/SMB. Key components include: What Is SAN? A SAN(Storage Area Network) is a dedicated high-speed network that connects servers…
Introduction: Blu-ray vs DVD – What’s the Difference? When comparing Blu-ray vs DVD, the main differences lie in resolution, storage capacity, and audio quality. Blu-ray offers a superior experience with sharper visuals and immersive sound, while DVDs are budget-friendly and widely compatible. What Is Blu-ray? Blu-ray discs employ a blue-violet laser with a shorter wavelength (405 nm) compared to the red laser (650 nm) used in DVDs, enabling higher storage densities. A single-layer Blu-ray disc can store up to 25 GB of data, while a dual-layer disc can hold up to 50 GB. This increased capacity allows for high-definition video…
