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).

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 set of means used to protect data, systems, and computer devices from cyber attacks. This may include, but is not limited to, the installation of an antivirus software.

Domain name

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.


A data transmission protocol that creates a local area network where devices are connected to a gateway or modem via an Ethernet cable. This type of wireline connection provides faster and more stable access to the Internet compared to a wireless (Wi-Fi) connection.


A software or hardware that provides security to a computer system by filtering the data transmitted to it.

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.

IP Address

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:


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

Port forwarding

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.

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 4

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.

Wi-Fi 5

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 6

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.

Wi-Fi pod
