What are common computer network devices and their functions? Describe the setup of networked computers in a lab.

Welcome back ELWAHIS — missed you this week. Here are the answers to your computer networking questions: Step 1: Identify network devices (Questions 1 & 2) The table below lists common computer network devices found in a laboratory or cyber cafe, along with their functions. Diagrams and specific prices cannot be provided in this text format. | No. | Name | Function | | :-- | :--- | :------- | | 1. | Router | Connects different networks and forwards data packets between them. | | 2. | Switch | Connects multiple devices within a local area network (LAN) and forwards data to the correct destination. | | 3. | Modem | Converts digital signals from a computer into analog signals for transmission over telephone lines or cable, and vice-versa, to connect to an ISP. | | 4. | Ethernet Cable | Physical medium used to transmit data in wired networks. | | 5. | Server | A powerful computer that provides resources, data, services, or programs to other computers (clients) over a network. | | 6. | Workstation/Client PC | An end-user computer used to access network resources and perform tasks. | | 7. | Wireless Access Point (WAP) | Allows wireless devices to connect to a wired network. | | 8. | Network Interface Card (NIC) | Hardware component that connects a computer to a network. | Step 2: Networked computers and topology (Questions 3 & 4) 3) Assuming a typical setup for a computer laboratory, the computers are networked. Yes 4) A common physical network topology used in laboratories and cyber cafes is the Star Topology. In a star topology, each device (computer, printer, etc.) is connected individually to a central device, such as a switch or a hub. All data traffic passes through this central device. Step 3: Network architecture and connection methods (Questions 5 & 6) 5) The computers in a laboratory or cyber cafe typically use a Client-Server Architecture. This architecture is preferred because it allows for centralized management of resources, security, and data. A central server can store files, manage user accounts, and provide services (like printing or internet access) to multiple client computers, making it efficient for shared environments. 6) The two primary ways in which devices can be connected to each other in a network are: • Wired Connection: Devices are physically connected using cables (e.g., Ethernet cables). • Wireless Connection: Devices communicate using radio waves without physical cables (e.g., Wi-Fi).
