We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
Dual band routers have two bands, 2.4GHz and 5GHz. The 5GHz band is faster and more stable, with the only downside being that it covers a shorter range than the 2.4GHz band. If you have many connected devices, you may benefit from a tri-band router, which has an additional 5GHz band to reduce network congestion. Finally, there are quad-band routers. These take advantage of Wi-Fi 6E to provide an additional 6GHz band for faster speeds and lower latency.
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
Random-access memory (RAM) is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.
The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.
With DNS relay or DNS caching, the router stores the response to queries for a short time. This means that the same query will return a quicker response if repeated from another computer in the same network.
The internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device.
WPA3 is a method of connecting to a Wi-Fi network that is more secure than the previous protocol (WPA2). Individual data is better encrypted and it is harder for hackers to gain the password with a brute-force attack.
WPA2-PSK is a method of securing your network using WPA2 (Wi-Fi Protected Access 2) as well as a Pre-Shared Key (PSK) password. This was designed for home users without an enterprise authentication server.
Normally, a router broadcasts the Wi-Fi signal in all directions. Using beamforming technology, the router detects where your device is and focuses a stronger signal in that direction, resulting in a better connection.
Matter is a standard for smart home devices. It is backed by various tech companies including Apple, Google, Amazon, and Samsung. The goal is to allow devices to be used across different systems, so you don't have to worry about compatibility issues.
