Across
  1. 1. A connection-oriented transport protocol that uses a three-way handshake (SYN, SYN-ACK, ACK) to ensure reliable, ordered, and error-checked data delivery.
  2. 4. A cloud service model where the provider manages the physical infrastructure, hypervisors, and operating systems, delivering a pre-configured execution environment for software developers to build, host, and scale applications.
  3. 5. Reserved IPv4 address blocks (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) designated exclusively for local private networks and non-routable across the public internet.
  4. 6. A 32-bit value that separates an IPv4 address into its Network ID and Host ID portions, allowing the operating system to determine if a destination host is local or remote.
  5. 9. A cloud service model where the provider hosts, manages, and maintains the entire application stack and underlying infrastructure. Users access the software directly via a web browser (e.g., Microsoft 365, Google Workspace).
  6. 10. A physical network layout where every client workstation connects directly to a central networking device (such as an Ethernet switch). A single cable break only affects one workstation.
  7. 13. The IP address of the local router interface that handles outbound traffic destined for networks outside the host's local IP subnet.
  8. 14. An Ethernet cable wired identically on both ends (e.g., T568B to T568B) used to connect unlike devices, such as a computer to an Ethernet switch.
  9. 17. A cloud service model where the provider delivers virtualized raw hardware resources (servers, storage blocks, virtual routers, firewalls). The customer remains responsible for managing the operating system, applications, middleware, and data.
  10. 18. A lightweight, connectionless transport protocol that transmits datagrams without establishing a connection or guaranteeing packet delivery, providing low latency for real-time traffic (such as VoIP or video streaming).
Down
  1. 2. A firewall configuration rule that redirects incoming communication requests on a specific WAN public IP address and port directly to a designated internal private LAN IP address and port.
  2. 3. A cloud infrastructure dedicated exclusively to a single organization, hosted either on-premises in a private data center or off-site by a third party, delivering maximum data privacy and control.
  3. 4. A short, flexible Ethernet cable (typically stranded UTP) used to connect end devices to wall outlets or patch panels inside telecommunication closets.
  4. 7. A high-speed memory table maintained by a Layer 2 switch that maps connected device physical MAC addresses to specific physical switch ports.
  5. 8. A cryptographic network protocol operating on TCP port 22 used for secure command-line shell access and remote administration.
  6. 11. A multi-tenant cloud environment where virtual computing resources owned by a third-party Cloud Service Provider (AWS, Azure, GCP) are delivered over the public internet on a pay-as-you-go basis.
  7. 12. Standardized syntax used in Windows environments to access network share folders and printers (e.g., \ServerName\ShareName).
  8. 15. Standard A standard commercial pinout color scheme for terminating twisted-pair Ethernet cables (Pin 1: Orange-White, Pin 2: Orange, Pin 3: Green-White, Pin 4: Blue, Pin 5: Blue-White, Pin 6: Green, Pin 7: Brown-White, Pin 8: Brown).
  9. 16. Standard networking cable containing pairs of insulated copper wires twisted together to cancel out electromagnetic interference and crosstalk without requiring an outer foil shield.
