Chapter 2 Flashcards
(30 cards)
What is a bus topology?
A network topology where all devices share a single communication line (backbone).
What is a key weakness of a bus topology?
If the backbone fails, the entire network goes down.
What is a star topology?
A topology where each device is connected to a central device like a switch or hub.
What is a key benefit of a star topology?
Easier fault isolation and scalability.
What is a ring topology?
A topology where devices are connected in a circular loop, with data traveling in one direction.
What is a main drawback of a ring topology?
A break in the ring can disrupt the entire network.
What is a mesh topology?
Each device connects directly to every other device, offering full redundancy.
What is the difference between full mesh and partial mesh topology?
Full mesh: all nodes interconnected. Partial mesh: only some nodes are directly connected.
What is a hybrid topology?
A combination of two or more different topology types.
Which topology is most fault-tolerant?
Full mesh topology.
What is a client-server network architecture?
A centralized model where servers provide resources and clients request them.
What is a peer-to-peer (P2P) network architecture?
A decentralized model where each device can act as both a client and a server.
Name a benefit of a client-server architecture.
Centralized administration, easier to manage and secure.
Name a disadvantage of a peer-to-peer network.
Lack of centralized management and harder to secure.
What is a LAN?
Local Area Network – covers a small geographical area like an office or building.
What is a WAN?
Wide Area Network – spans large geographical areas, often made up of multiple LANs.
What is a MAN?
Metropolitan Area Network – spans a city or large campus area.
What is a PAN?
Personal Area Network – used for devices within a few meters (e.g., Bluetooth, USB).
What is a WLAN?
Wireless Local Area Network – a LAN that uses Wi-Fi instead of cables.
What is a CAN?
Campus Area Network – interconnects multiple LANs within a limited area like a university or business park.
What is a SAN?
Storage Area Network – a dedicated network for data storage and transfer between servers and storage devices.
What is an intranet?
A private internal network used within an organization, often built using web technologies.
What is an extranet?
A controlled private network that allows external partners limited access to internal resources.
What is unicast?
One-to-one communication between a single sender and a single receiver.
