Network Components
A computer that gets information, makes requests from another computer called server.
What is CLIENT?
The main advantage of this device is enabling communication between different networks?
What is the advantage of a ROUTER?
This network component enables communication between the nodes in a network. But it creates a lot of network traffic by sending the data packets to all devices including the sender itself
What is the disadvantage of a HUB?
A small network covering only a few meters, usually used for a few devices only.
What is PAN?
That is a physical and logical arrangement of nodes and connections in a network
What is topology?
A server that manages sending and recieving emails messages using outgoing and incoming email protocols.
What is EMAIL SERVER?
A key benefit is reducing network congestion by directing data to specific devices.
What is the advantage of a SWITCH?
It’s a hardware component for wireless communication which has a limited range, and physical barriers can affect its range due to it using air to transmit.
What is the disadvantage of a WAP?
This type of network covers a bigger area; for example an office or a school. Can connect multiple devices to a few hundred.
What is LAN?
Bus topology, Mesh topology, Ring topology, Star topology, Hybrid topology, Tree topology.
What are the diferent types of topologies?
The physical medium used to carry data across the network, which can be wired (cables like Ethernet) or wireless (Wi-Fi, Bluetooth).
What is transmission media?
The primary advantage is to provide security in a network by blocking unauthorized access.
What is the advantage of FIREWALL?
A major disadvantage in this model of network is the absence of centralized control, making it difficult to enforce policies, ensure data integrity, and coordinate complex tasks.
What is the disadvantage of P2P network?
Covers a large geographical area. For example a university with campuses in different cities connected via dedicated fiber optic links to share resources and maintain centralized administration.
What is WAN?
This topology consists of a single cable which the various nodes are attached. Transmission from any node travels through the cable in both directions and can be received by all other stations.
What is a BUS topology?
A dedicated, single point failure storage server that allows multiple users and devices on a local area network to acces data from a centralized storage area of network.
What is NAS?
This topology provides redundancy and ensures network reliability even if one node fails.
What is the advantage of MESH topology?
It adds complexity to a local area network, in setup and management, as its virtual nature requires careful configuration, which requires specialized knowledge, increasing the risk of errors or security issues.
What are the disadvanatges of VLAN?
A subdivision within a physical network that separates and isolates traffic. It can divide a single physical LAN into multiple virtual networks, even when devices are connected to the same switches or infrastructure.
What is VLAN?
A type of network configuration where devices are connected in a circular manner, forming a closed loop.
What is RING topology?
A distributed database system that translates human-readable domain names (e.g., `www.example.com`) into machine-readable IP addresses (e.g., `192.0.2.1`)
What is DNS SERVER?
This type of network ensures secure communication through encryption over public networks.
What is the advantage of VPN?
It is network of storages that requires special hardware that is costly and needs to be configured correctly. This makes it attractive only to larger businesses.
What is the disadvantage of SAN?
Larger than СAN, can cover several square miles. Usually owned by the large organisations, city, or government
What is MAN?
A network configuration where devices are interconnected in a decentralized manner. P2P model uses this topology.
What is MESH topology?
