Networking Basics Quiz

Networking Basics

• Definition: Networking refers to the process of connecting devices, such as computers, printers, and servers, to share resources and exchange data.
• Types of Networks:
  • LAN (Local Area Network): connects devices in a limited geographical area, such as a home or office building.
  • WAN (Wide Area Network): connects devices over a larger geographical area, such as a city or country.
  • MAN (Metropolitan Area Network): connects devices in a metropolitan area, such as a city or town.
  • WLAN (Wireless Local Area Network): connects devices wirelessly in a limited geographical area.
  • Wi-Fi: a type of WLAN that uses radio waves to connect devices.

Network Topology

• Definition: Network topology refers to the physical and logical arrangement of devices and connections in a network.
• Types of Network Topology:
  • Physical Topology:
    • Bus Topology: a single cable connects all devices in a linear sequence.
    • Star Topology: all devices connect to a central device or hub.
    • Ring Topology: devices connect in a circular configuration.
  • Logical Topology:
    • Mesh Topology: each device connects to every other device.
    • Tree Topology: a combination of bus and star topologies.

Network Protocols

• Definition: Network protocols are the set of rules and standards that govern data communication over a network.
• Examples of Network Protocols:
  • TCP/IP (Transmission Control Protocol/Internet Protocol): the most widely used protocol suite for the internet.
  • HTTP (Hypertext Transfer Protocol): used for transferring data over the web.
  • FTP (File Transfer Protocol): used for transferring files over a network.
  • DNS (Domain Name System): used for resolving domain names to IP addresses.

Network Devices

• Definition: Network devices are hardware components that connect devices and facilitate communication over a network.
• Examples of Network Devices:
  • Hubs: simple network devices that connect multiple devices.
  • Switches: intelligent network devices that connect multiple devices and manage traffic.
  • Routers: devices that connect multiple networks and manage traffic between them.
  • Modems: devices that connect to the internet via a broadband connection.

Network Security

• Definition: Network security refers to the measures taken to protect a network from unauthorized access, use, or theft.
• Threats to Network Security:
  • Hacking: unauthorized access to a network.
  • Malware: malicious software that can damage or exploit a network.
  • Viruses: malicious software that can replicate and spread across a network.
  • Phishing: attempts to steal sensitive information by posing as a trusted entity.
• Measures to Ensure Network Security:
  • Firewalls: network devices that block unauthorized access.
  • Encryption: encrypting data to prevent interception.
  • Authentication: verifying the identity of devices and users.
  • Access Control: restricting access to authorized devices and users.
