Client-Server Network

                 Client-server architecture is a network design with two main roles: clients and servers. Clients
                 request servers for resources or services, such as a Web page. These resources are provided and
                 managed by servers. For example, a web browser (client) asks a web server for a Web page, and
                 the server delivers it. The Internet commonly uses this setup for accessing and hosting websites.

                    WIRELESS NETWORKING TECHNOLOGY

                 In wireless  networking, computers connect without using physical wires. Instead, it relies on
                 electromagnetic  waves such as infrared,  microwaves, and radio  waves to transmit data.  The
                 type of technology used depends on the distance and speed needed. Two common wireless
                 technologies are Wi-Fi and Bluetooth.
                 Wi-Fi

                 Wireless  Fidelity  (Wi-Fi) is  a widely used wireless
                 communication technology for homes, businesses, local
                 area networks (LANs), and public hotspots. Devices like
                 PCs, game consoles, mobile phones, and MP3 players can
                 connect to the Internet when they are within range of a
                 Wi-Fi  network.  Wi-Fi  enables local area  networks  to be
                 created without the need for cables, making it easier and
                 more cost-effective to expand the network.

                                                        Bluetooth

                                                        Bluetooth is a technology that enables low-power devices
                                                        to communicate wirelessly over short distances, usually up
                                                        to 100 meters. It allows devices, such as mobile phones,
                                                        laptops,  printers,  and  GPS receivers,  to connect  and

                                                        exchange  information.  The  latest version,  Bluetooth  5.4,
                                                        supports data transfer speeds of up to 2 Mbps and uses a
                                                        2.4 GHz radio frequency.
