Packet Tracer allows students to design complex and large networks, which is often not feasible with physical hardware, due to costs. [7] Packet Tracer is commonly used by NetAcad students, since it is available to download after creating a free account. [ 10 ]
High-Level Data Link Control (HDLC) is a communication protocol used for transmitting data between devices in telecommunication and networking.Developed by the International Organization for Standardization (ISO), it is defined in the standard ISO/IEC 13239:2002.
The Edge Gateway layer consists of sensor data aggregation systems called Edge Gateways that provide functionality, such as pre-processing of the data, securing connectivity to cloud, using systems such as WebSockets, the event hub, and, even in some cases, edge analytics or fog computing. [140]
All data structures in the OneFS file system maintain their own protection information. This means in the same filesystem, one file may be protected at +1 (basic parity protection) while another may be protected at +4 (resilient to four failures) while yet another file may be protected at 2x (); this feature is referred to as FlexProtect.

This is due to the fact that surface waters in polar latitudes are nearly as cold as deeper waters. Below the thermocline, water everywhere in the ocean is very cold, ranging from −1 °C to 3 °C. Because this deep and cold layer contains the bulk of ocean water, the average temperature of the world ocean is 3.9 °C. [90]
