Fourth Dimension Technologies Interview Questions and Answers

The OSI model is a conceptual framework for understanding network communication in seven layers.

• Layer 1: Physical - Deals with the physical connection (e.g., cables, switches).

• Layer 2: Data Link - Manages node-to-node data transfer (e.g., Ethernet).

• Layer 3: Network - Handles routing of data (e.g., IP addresses).

• Layer 4: Transport - Ensures complete data transfer (e.g., TCP, UDP).

• Layer 5: Session - Manages sessions betw...read more

TCP and UDP port numbers are used to identify specific processes or services on a device in network communications.

• TCP (Transmission Control Protocol) is connection-oriented, ensuring reliable data transmission.

• UDP (User Datagram Protocol) is connectionless, allowing faster data transmission without guaranteed delivery.

• Common TCP port examples: 80 (HTTP), 443 (HTTPS), 22 (SSH).

• Common UDP port examples: 53 (DNS), 67 (DH...read more

TCP/IP model is a networking protocol suite that defines how data is transmitted over a network.

• Consists of four layers: Application, Transport, Internet, Link

• Each layer has specific functions and protocols

• Example: HTTP operates at the Application layer, TCP at the Transport layer

DNS (Domain Name System) translates domain names into IP addresses, enabling users to access websites using easy-to-remember names.

• DNS is essential for the functionality of the internet, allowing users to navigate using domain names instead of numerical IP addresses.

• It operates on a hierarchical structure, with root servers at the top, followed by TLD (Top-Level Domain) servers and authoritative servers.

• For example, wh...read more
