In an international online gaming tournament, players from around the world need to ensure minimal latency and packet loss. The effectiveness of this is largely dependent on which aspect of networking?
- Bandwidth
- Network Topology
- Quality of Service (QoS)
- Routing Protocol
Quality of Service (QoS) is crucial in this context. QoS ensures that the network can prioritize gaming traffic to minimize latency and packet loss, providing a better gaming experience for players.
A device's _______ address remains constant even if its IP address changes within a network.
- DHCP
- DNS
- IP
- MAC
A device's MAC (Media Access Control) address is a unique hardware address assigned to the network card and remains constant, even if the device's IP address changes within a network due to dynamic addressing from DHCP.
Ethernet's evolution started with 10BASE-T, with the "10" indicating the speed of _______ Mbps.
- 1
- 10
- 100
- 1000
In 10BASE-T, the "10" signifies the network speed, which is 10 Mbps (Megabits per second). This was one of the early Ethernet standards using twisted-pair cables.
Which Ethernet standard introduced 100 Gigabit per second speeds?
- 1000Base-T
- 100Base-T
- 100GBase-T
- 10GBase-T
The 100GBase-T Ethernet standard introduced 100 Gigabit per second speeds over twisted-pair copper cables, making it a significant advancement in high-speed networking.
How does the Stop-and-Wait protocol handle lost frames or acknowledgments?
- It automatically resends lost frames
- It ignores lost frames and continues transmitting
- It retransmits the lost frame or waits for a timeout and then retransmits
- It waits indefinitely for lost acknowledgments
The Stop-and-Wait protocol handles lost frames or acknowledgments by retransmitting the lost frame or waiting for a timeout before retransmitting. This ensures that the receiver eventually receives the frame, preventing data loss.
What is the primary purpose of protocols in computer networking?
- To ensure data security
- To provide physical network infrastructure
- To facilitate communication between devices
- To display web pages
The primary purpose of protocols in computer networking is to facilitate communication between devices. Networking protocols define a set of rules and conventions that devices follow to communicate effectively on a network. These rules govern how data is formatted, transmitted, received, and processed across the network.
When a company wants to divide its IP address space into smaller, more manageable blocks, it is engaging in ___________.
- Port forwarding
- Subnetting
- Supernetting
- VLAN configuration
Subnetting is the process of dividing an IP address space into smaller, more manageable blocks, often called subnets. It is used to efficiently allocate IP addresses and improve network organization and management.
Which of the following is NOT a common error-handling technique used in the transport layer?
- Error Detection
- Flow Control
- Framing
- Retransmission
Framing is not typically considered a common error-handling technique in the transport layer. Error detection is used to identify and correct errors in transmitted data. Flow control helps manage the speed of data transmission, and retransmission handles the retransmission of lost or corrupted data.
Which protocol would be more suitable for streaming videos where occasional data loss is acceptable?
- HTTP (Hypertext Transfer Protocol)
- IP (Internet Protocol)
- TCP (Transmission Control Protocol)
- UDP (User Datagram Protocol)
UDP (User Datagram Protocol) is suitable for streaming videos where occasional data loss is acceptable. UDP is connectionless and does not guarantee data delivery, but it offers lower latency, making it ideal for real-time applications like video streaming.
What kind of message does the "ping" command primarily use to check the reachability of a network device?
- ARP Request
- ICMP Echo Request
- TCP SYN
- UDP Packet
The "ping" command primarily uses ICMP Echo Request messages to check the reachability of a network device. It sends these messages to the target device, which should respond with an ICMP Echo Reply if it's reachable.
