Public Wi-Fi hotspots offer convenience but come with serious security risks. Cybercriminals often target these networks to intercept sensitive data, including passwords and financial details. The FBI warns that even hotel Wi-Fi can be vulnerable to attacks. Without proper protection, your personal information could be exposed. Hackers use techniques like man-in-the-middle attacks to steal credentials….
Modern computer networks rely on efficient error-control methods to ensure smooth data transmission. Among these, selective repeat stands out as a powerful sliding window protocol. It enhances reliability by resending only lost or corrupted frames, saving bandwidth and time. Operating at the data link layer, this method outperforms alternatives like Go-Back-N. Unlike traditional approaches, it…
Telnet remains a foundational network protocol for remote access across different systems. Developed in 1969, it allows users to control devices through Internet or LAN connections using TCP. This client-server tool proves valuable for administrators and developers working with multiple platforms. The protocol operates on port 23, transmitting data without encryption. While convenient, this creates…
Digital communication relies on accurate data transfer. A checksum serves as a unique fingerprint, verifying information remains unchanged during transmission. This simple yet powerful tool helps identify errors before they cause problems. Modern systems generate these values using algorithms like MD5 or SHA-256. When files move across networks, the receiving system recalculates and compares the…
Adding to your home network is easier than you might think. Ethernet is still the top choice for networking. It offers fast, reliable connections with minimal setup hassle1. Home networks now have many connection options. Wi-Fi has become popular, offering wide coverage. A typical network can support multiple devices using a switch or router12. Adding…
Home network administration can be puzzling. If you’re at home, you’re the network admin for your computer system1. Windows often shows messages suggesting a separate network administrator exists1. Home users typically have full admin rights on their machines. The standard login account usually has complete control1. There’s no special network admin login; the admin account…
Remote access has revolutionised how professionals interact with digital resources across networks. It allows users to connect to computers from anywhere, breaking traditional geographical limits1. Modern strategies enable secure access to desktop computers via internet connectivity. Professionals can now manage tasks, retrieve files, and offer technical support from any location1. Remote access involves creating a…
Servers are specialised computers that provide resources across networks. These powerful machines act as central hubs for data sharing. In digital ecosystems, servers manage network interactions and support various technological functions12. A server processes requests sent over a network and responds to client machines. It can manage multiple client connections simultaneously. This creates a robust…
