SMB, work environments, refers to Server Message Block, a network communication protocol primarily used for sharing files, printers, and other resources between computers on a network. It facilitates seamless data transfer and resource sharing within organizations, enabling users to access and collaborate on files stored on shared drives, servers, or network-attached storage (NAS) devices. SMB … Read more
WPA2 (Wi-Fi Protected Access 2) and WPA3 (Wi-Fi Protected Access 3) are security protocols used to secure wireless networks. WPA2 has been the standard for many years and provides strong encryption and authentication methods to protect Wi-Fi networks from unauthorized access and attacks. It uses the AES (Advanced Encryption Standard) protocol for encryption and provides … Read more
The SMB (Server Message Block) protocol is used primarily for sharing files, printers, and other resources between computers on a network. It enables seamless communication and data transfer between client devices (such as computers, printers) and SMB servers, facilitating collaborative work environments where users can access and manipulate shared files stored on networked devices. SMB … Read more
WPA2 is used to secure Wi-Fi networks by providing encryption and authentication mechanisms that prevent unauthorized access to network communications. It ensures that data transmitted wirelessly between devices and the Wi-Fi access point is encrypted, thereby protecting sensitive information such as passwords, credit card details, and personal data from being intercepted by unauthorized users. When … Read more
ICMP (Internet Control Message Protocol) is a network protocol used for sending error messages and operational information indicating issues encountered during data transmission. It operates at the network layer (Layer 3) of the OSI model and is primarily used by network devices, such as routers and switches, to communicate status and error information. ICMP messages … Read more
Zigbee is a wireless communication technology designed for low-power, low-data-rate applications in wireless sensor networks and Internet of Things (IoT) devices. It operates on the IEEE 802.15.4 standard and uses the 2.4 GHz frequency band (in most regions) for communication. Zigbee enables devices to communicate wirelessly over short distances, typically up to 10-100 meters, and … Read more
IGMP (Internet Group Management Protocol) is used to manage multicast group memberships on IPv4 networks. Its primary purpose is to allow hosts to join or leave multicast groups dynamically, enabling efficient distribution of multicast traffic within a network. By using IGMP, hosts can signal their interest in receiving multicast packets destined for specific multicast group … Read more
There are four primary types of networks based on their geographical scope and coverage: Local Area Network (LAN): A LAN is a network that covers a small geographic area, typically within a single building or campus. It connects computers, servers, printers, and other devices to facilitate data sharing, communication, and resource sharing within a limited … Read more
IP mirroring involves duplicating IP traffic from one source to another destination. This process allows monitoring or analyzing network traffic without disrupting normal operations. It’s commonly used for debugging, security analysis, or network performance monitoring. Port mirroring, also known as SPAN (Switched Port Analyzer) or port monitoring, involves forwarding a copy of network packets from … Read more
Network hardware consists of various components that enable communication and data transfer within computer networks. Here are seven common pieces of network hardware: Router: A router is a networking device that forwards data packets between computer networks. It operates at the network layer (Layer 3) of the OSI model and determines the best path for … Read more
