Spectrum refers to the range of frequencies used for wireless communication. It is divided into different bands, each with its own specific purpose and regulations. Examples of spectrum bands include 2.4 GHz for Wi-Fi and 5G for mobile networks.
16. Telephony
Telephony is the technology and service of transmitting voice and other forms of communication over a distance. It includes traditional telephone services, as well as newer technologies such as Voice over Internet Protocol (VoIP).
17. Unified Communications
Unified Communications (UC) refers to the integration of various communication and collaboration tools, such as voice, video, messaging, and conferencing, into a single platform. It enables users to communicate and work together in real-time, regardless of their location or device.
18. Virtual Private Network (VPN)
A Virtual Private Network (VPN) is a secure connection that allows users to access a private network over the internet. It is commonly used to protect sensitive data and provide remote access to corporate networks.
19. Web Conferencing
Web Conferencing is a technology that enables users to hold virtual meetings, presentations, and webinars over the internet. It typically includes features such as video and audio conferencing, screen sharing, and chat.
20. Wi-Fi
Wi-Fi is a wireless networking technology that allows devices to connect to the internet and other networks without the need for physical cables. It uses radio waves to transmit data and is commonly used in homes, offices, and public spaces.
21. 3G/4G/5G
3G, 4G, and 5G refer to different generations of mobile network technology. 3G (Third Generation) provides faster data transfer speeds than 2G and enabled the use of mobile internet. 4G (Fourth Generation) offers even faster speeds and improved network capacity. 5G (Fifth Generation) is the latest and fastest mobile network technology, with the potential to support advanced applications such as autonomous vehicles and virtual reality.
22. API
API (Application Programming Interface) is a set of protocols, tools, and definitions that enable different software applications to communicate with each other. It allows developers to integrate different systems and services, creating a more seamless user experience.
23. Firewall
A firewall is a security system that monitors and controls incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and an untrusted external network, protecting against unauthorized access and cyber threats.
24. Latency
Latency is the time delay between the transmission and reception of data. It is a crucial factor in determining the speed and efficiency of data transmission and is typically measured in milliseconds (ms).
25. VoIP
VoIP (Voice over Internet Protocol) is a technology that enables voice communication over the internet. It converts analog voice signals into digital data and transmits them over a network, allowing for more efficient and cost-effective communication.
