Network Infrastructures
What device connects multiple computers within a local area network (LAN) and forwards data packets between them?
What is a "switch"?
What type of network covers a broad area, often spanning multiple cities or even countries?
What is a "Wide Area Network (WAN)"?
What technology allows devices to connect to a network without the need for physical cables?
What is "wireless networking" or "Wi-Fi"?
What network topology connects all devices in a linear fashion, where each device is connected to exactly two other devices, except for the endpoints?
What is the Bus Topology?
What everyday object did the term "packet" originate from in computer networking?
What is a "packet" was originally inspired by the concept of a "parcel" or "packet" in postal systems?
This protocol assigns IP addresses dynamically to devices on a network.
"Dynamic Host Configuration Protocol (DHCP)"?
This technology allows multiple devices to share a single public IP address to access the internet.
What is "Network Address Translation (NAT)"?
This protocol is commonly used to secure wireless networks by encrypting data transmissions.
What is "Wi-Fi Protected Access (WPA/WPA2)"?
In this topology, each device is connected to a central hub or switch, forming a star-like structure. What is it called?
What is the Star Topology?
What pioneering technology, developed in the 1960s, paved the way for modern computer networking?
What is ARPANET, the precursor to the internet?
What network device operates at the Data Link layer of the OSI model and forwards data based on MAC addresses?
What is a "router"?
What protocol is commonly used to establish secure connections between remote locations over a wide area network?
What is "Secure Shell (SSH)"?
What is the name of the unique identifier assigned to each wireless network, used by devices to identify and connect to it?
What is a "Service Set Identifier (SSID)"?
What network topology combines elements of the bus and star topologies, where devices are connected in a closed loop, and data travels in one direction?
What is the Ring Topology?
What groundbreaking technology, introduced in 1983, standardized the rules for transmitting data packets across diverse networks?
What is the Transmission Control Protocol/Internet Protocol (TCP/IP)?
This protocol allows secure remote access to a network over an unsecured network, such as the internet, by creating a secure tunnel for data transmission.
What is "Virtual Private Network (VPN)"?
What is the name of the network topology commonly used in WANs, where multiple sites are connected in a point-to-point fashion, forming a mesh-like structure?
What is a "Mesh Topology"?
What technology, commonly used in wireless networks, allows devices to communicate with each other directly without needing to connect to a traditional access point?
What is "Ad-hoc Mode" or "Peer-to-Peer Networking"?
In this topology, each device is connected to every other device in the network. It offers high redundancy but can become complex to manage as the network grows. What is it?
What is the Mesh Topology?
What high-speed networking technology, developed in the late 20th century, replaced traditional copper wire connections with fiber-optic cables for long-distance communication?
What is Fiber-optic communication or Fiber-optic networking?
In networking, this term refers to the maximum data transfer rate of a network or internet connection.
What is "bandwidth"?
This WAN technology, developed by telecommunications carriers, allows the integration of voice, data, and video services over a single network infrastructure.
What is "Multiprotocol Label Switching (MPLS)"?
This wireless networking standard, known for its high data transfer rates and commonly used in home and business networks, operates in the 2.4 GHz and 5 GHz frequency bands.
What is "802.11ac"?
This topology is characterized by a decentralized structure where each device communicates directly with every other device in the network. It's highly resilient but often requires sophisticated routing algorithms. What is it?
What is the Fully Connected or Full Mesh Topology?
What is the name of the decentralized, peer-to-peer network protocol developed by Bram Cohen in 2001, primarily used for distributing large files over the internet?
What is BitTorrent?
