WPA2 (Wi-Fi Protected Access 2) is used to secure wireless networks, providing encryption and authentication mechanisms to protect data transmitted over Wi-Fi connections. It is widely used across home and enterprise networks to safeguard sensitive information such as passwords, financial transactions, and personal data from unauthorized access and interception by malicious actors. Between WPA and … Read more
A Wi-Fi controller, often referred to as a Wireless LAN Controller (WLC), serves as a centralized management device for wireless networks. Its primary use is to oversee and coordinate multiple access points (APs) within a wireless network infrastructure. The Wi-Fi controller enables administrators to configure, monitor, and manage Wi-Fi access points from a single interface, … Read more
The two main types of network security can be broadly categorized as preventive and detective measures. Preventive measures aim to stop security incidents from occurring by implementing controls such as firewalls, encryption, access controls, and authentication mechanisms. Detective measures, on the other hand, focus on identifying security breaches or incidents that have already occurred through … Read more
A wireless controller, such as a Wireless LAN Controller (WLC), functions by centralizing the management and coordination of wireless access points (APs) within a network. It operates as a dedicated device or software application that communicates with APs over the network. The WLC acts as a centralized point of control, allowing administrators to configure AP … Read more
Powerline networking utilizes existing electrical wiring within buildings to create a network connection. It allows devices to communicate and share data through the electrical outlets, effectively extending a network without the need for additional Ethernet cables or Wi-Fi signals. This technology is particularly useful in situations where Wi-Fi signals are weak or unreliable, or where … Read more
A LAN card, also known as a network interface card (NIC) or Ethernet adapter, is used to connect a computer or device to a local area network (LAN). Its primary function is to enable communication between the device and other devices or servers within the same LAN. The LAN card interfaces with the computer’s motherboard … Read more
A power line connection refers to using electrical wiring in buildings to establish a network connection between devices. It utilizes powerline networking technology where adapters plug into electrical outlets, allowing data to be transmitted through the existing electrical wiring. This method provides an alternative to traditional wired Ethernet or wireless Wi-Fi connections. Powerline connection, networking, … Read more
A Network Interface Card (NIC) from Cisco, often referred to simply as a network interface card Cisco, is a hardware component used to enable network connectivity in Cisco networking devices such as routers, switches, and servers. Cisco NICs are designed to support various network protocols and standards, ensuring compatibility with Cisco networking equipment and environments. … Read more
The principle of fiber optics revolves around the transmission of light through thin, flexible strands of glass or plastic fibers. These fibers are designed to guide light along their length by using the principle of total internal reflection. When light enters the core of the fiber at a shallow angle, it undergoes multiple internal reflections … Read more
Fibre optics is also known as optical fiber or fiber optics. These terms are used interchangeably to describe the technology and method of transmitting light signals through thin, transparent fibers made of glass or plastic. Another word for fibre optics is “optical communication.” This term emphasizes the use of light signals to transmit data over … Read more
