Computer networks connect multiple devices, enabling seamless data sharing and communication. These systems have evolved significantly since their inception, transforming how we interact with technology. The first operational network, ARPANET, was developed in the late 1960s. Funded by the Department of Defense, it laid the foundation for modern internet infrastructure. Today, networks support diverse applications,…
Repeaters have a key role in expanding computer networks. They boost the network reach by amplifying signals strongly and clearly. These devices are crucial in both wired and wireless networks. They boost signal strength, helping messages travel further. Repeaters work at the physical layer, ensuring data moves accurately across longer distances. This helps Local Area…
Computer networks are crucial for today’s communication, allowing different devices to share data and resources. The concept started in the late 1960s with ARPANET, funded by the Department of Defense. They now power essential services like the internet, email, and cloud computing. They use both wired and wireless links to transfer data quickly and adapt…
In computer networks, the role of frequency is crucial. It helps define how data is transmitted effectively. Frequency affects speed, reliability, and how far a signal can travel. Measured in Hertz (Hz), frequency shows how often something happens. For modern networks, this knowledge is key. It touches on everything from wireless systems to network performance….
