Software that can detect computer viruses and remove them from a device or network.
Data transmission capacity of a communications channel, such as an Internet access. It is expressed in bits per second. The higher the bandwidth, the stronger the Internet network.
A basic unit that designates a quantity of computer data. It is used to measure the memory capacity of a device.
- 1 kilobit (Kbit) = 1,000 bits
- 1 megabit (Mbit) = 1,000,000 bits
- 1 gigabit (Gbit) = 1,000,000,000 bits
Internet speed is generally measured in megabits per second (Mbps) or gigabits per second (Gbps).
Wireless connection technology. It allows two devices to exchange data over a short distance via a radio link. Wireless headphones, for example, use Bluetooth technology.
Software designed to view and display Web content. The main browsers are Google Chrome, Safari, Firefox, and Microsoft Edge.
Computer memory capacity unit. One byte consists of eight bits. The byte is used to measure the storage capacity of a device, such as a hard drive or memory card.
- 1 kilobyte (KB) = 1,000 bytes
- 1 megabyte (MB) = 1,000,000 bytes
- 1 gigabyte (GB) = 1,000,000,000 bytes
- 1 terabyte (TB) = 1,000,000,000,000 bytes

A malicious computer operation designed to hijack a system in order to steal, extort, expose, or destroy data.
Internet address consisting of a string of easily memorable characters that is linked to an IP address. This is the unique name that appears after the “@” sign in the email addresses and after “www” in the Web addresses.
Data transfer from a remote computer to a user’s device. For example, downloading occurs when an email attachment is saved to your computer. This is called a downstream transfer.

Internet of things (IoT)
A network of smart devices connected to the Internet for the purpose of exchanging information or automating certain features. For example, home automation is based on the IoT to facilitate automation or remote control of some household appliances. The IoT also has applications in areas such as industrial production, health, and transport.
The unique identification number of a computer that is connected to the Internet. This number can be used to locate a connected device, like a mailing address. The IP address is composed of four numbers separated by a period. For example: 188.8.131.52.
Delay between the time you launch a command on a device and the time the expected result occurs. It is measured in milliseconds (known as ping). The lower the latency, the faster and smoother the Internet connection.
Local area network

Electronic messaging protocol that allows you to retrieve emails hosted on a remote server. Retrieved emails are uploaded to the user’s device and deleted from the server. The letters POP refer to Post Office Protocol.
The redirection of incoming data on a device from one port to another. Ports are like gateways that protect the network and allow protected browsing on the Internet. To function properly, some apps (e.g. video games, instant messaging, IP telephony) require a designated port. You then need to set up a port redirection to use them. See how to perform a port redirection with the Helix Fi app.
Malware that blocks or encrypts data from a device or network and claims money from the user to return it.
The act of accessing a device or network from a remote location.
A program that allows a keyword search of Web resources to find the most relevant content. Search engines are used within a browser. The main search engines are Google, Bing, and Yahoo.

A wireless communication protocol that works with radio waves in a frequency band of 2.4 or 5 GHz. Using a gateway or router, Wi-Fi connects computer equipment and mobile devices to the Internet. “Wi-Fi” is a contraction of “Wireless Fidelity.” There are different Wi-Fi standards, including Wi-Fi 4, Wi-Fi 5 , and Wi-Fi 6.
Wi-Fi standard developed in 2009 that enabled the use of very high speed and the two frequency bands 2.4 and 5 GHz. It is still the most widely used standard in the world today.
A standard that has significantly improved Wi-Fi speeds since 2013. It only uses the frequency band 5 GHz. This standard is used infrequently because, while it provides faster speeds, it covers a smaller area.
Wi-Fi standard developed in 2021 that offers a significantly improved speed over previous standards. It is still new and is gradually replacing Wi-Fi 4 and Wi-Fi 5. This is the Wi-Fi standard used by Helix Fi gateways.
A small device plugged into a power outlet, which repeats a Wi-Fi signal to extend the reach of the network in a home. Learn more about Wi-Fi pods.
Wireless local area network
A small network that relies primarily on the transmission of data over radio waves. It is used to connect devices from the same household or company to avoid complex wiring operations. It can also be referred to as the acronym WLAN.
