IPv4 uses a 32-bit address space, allowing for about 4.3 billion unique addresses, whereas IPv6 uses a 128-bit address space, enabling a practically infinite number of addresses (3.4×10^38). We are transitioning due to the exhaustion of IPv4 addresses and the need for more unique IP addresses for modern devices, IoT, and future scalability. 2. Explain how TCP differs from UDP in terms of reliability, connection orientation, and flow control. When would you use one over the other? TCP (Transmission Control Protocol) is connection-oriented, reliable, and ensures data integrity through mechanisms like flow control, error detection, and retransmission. It is used for applications like HTTP, FTP, and email. UDP (User Datagram Protocol) is connectionless, faster, but unreliable and doesn't ensure data ...

  What is a Computer Network? A computer network is a collection of computers, servers, mainframes, network devices, and other devices connected to share data and resources. These devices can communicate with each other over a variety of transmission media like cables, wireless connections, or satellite links. A network enables resource sharing such as files, printers, and internet access between connected devices. How Do Computer Networks Work? Networks work by using protocols to govern the communication between devices. These protocols include TCP/IP, HTTP, FTP, and many others. These protocols define the rules for data transfer, error checking, and communication between devices. A network can be connected via wired (e.g., Ethernet) or wireless (e.g., Wi-Fi, Bluetooth) connections. Routers and switches play key roles in routing data efficiently across the network. Advantages of Computer Networks: Resource Sharing: Users can share resources like printers, files, and internet conn...
