Lesson 3 Question and answers
already passed 2026
Local area networks (LAN) - correct answer ✔connect computers within a single office or building
Wide Area Network (WAN) - correct answer ✔span multiple locations linking businesses and data
centers globally
Networking's business applications - correct answer ✔enable customer management systems,
inventory tracking, and cloud-based tools that improve efficiency.
Networking's effect on Collaboration and communication - correct answer ✔Employees use networks
to exchange emails, participate in video calls, and work on shared documents in real time.
Networking's Role in Operational efficiency - correct answer ✔By connecting databases, cloud
platforms, and software applications, networks streamline processes and ensure access to accurate,
real-time information.
Networking's role in Remote Access - correct answer ✔Cloud-based networks provide employees with
secure access to company resources from anywhere, supporting flexible and hybrid work environments.
Server - correct answer ✔Servers act as the central processing hub within a network they are high-
performance computers that manage and distribute network resources, enabling file storage, database
hosting, application deployment, and communication services.
Router - correct answer ✔Directs data between different networks and provides internet access
, Switch - correct answer ✔connects multiple devices within a local network, ensuring fast and efficient
data transfer
Modem - correct answer ✔converts digital data into signals for internet access, enabling
communication with an internet service provider (ISP)
Network interface Card (NIC) - correct answer ✔a hardware component that allows a computer or
device to connect to a network via wired or wireless communication
Network Topology - correct answer ✔physical and logical layout of how different devices are
connected within a network
Star Topology - correct answer ✔Devices are connected to a central hub or switch.
Mesh Topology - correct answer ✔Devices are interconnected, where each device is directly
connected to every other device.
Point-to-point topology - correct answer ✔This is a direct connection between two devices.
Bus Topology - correct answer ✔A single backbone cable connects all devices.
Ring Topology - correct answer ✔Devices are connected in a circular manner, each device linking to
two others.
Tree Topology - correct answer ✔This is a hybrid of star and bus, where groups of star networks are
connected in a hierarchical manner.
