Computer Network Quiz
Which statement describes the physical topology for a LAN
A) It defines how hosts and network devices connect to the LAN.
B) It shows the order in which hosts access the network.
C) It depicts the addressing scheme that is employed in the LAN.
D) It describes whether the LAN is a broadcast or token-passing network.
The Correct Answer Is:
- A) It defines how hosts and network devices connect to the LAN.
LAN defines how hosts and network devices connect to the LAN. A LAN, or Local Area Network, is a network of devices that allows communication between computers and other devices in a relatively small area. LANs are often used in homes, offices, and other small businesses.
LANs typically use Ethernet for the physical connection between devices. Ethernet is a technology that uses cables to connect devices to the network. Ethernet is a popular choice for LANs because it is inexpensive and easy to use.LANs can also be wireless, using technologies such as WiFi or Bluetooth. Wireless LANs are becoming more popular as they offer greater flexibility and easier installation than wired LANs.
Which statement describes the ping and tracert commands
a) Tracert shows each hop, while ping shows a destination reply only.
b) Both ping and tracert can show results in a graphical display.
c) Tracert uses IP addresses; ping does not.
d) Ping shows whether the transmission is successful; tracert does not.
Tracert shows each hop, while ping shows a destination reply only. When you want to know where a packet is going and how it’s getting there, you use the Tracert command. Tracert shows each hop, while ping only shows a destination reply. To use Tracert, open the Command Prompt and type “tracert” followed by the address or hostname you want to trace. For example, to find out the route to Google’s DNS servers, you would type: tracert 22.214.171.124 Tracert will show you the IP address of each hop, the round-trip time (in milliseconds), and the number of hops. The first hop is always your own router, so you can ignore that. The last hop should be the destination address.
Physical or logical arrangement of network is called
C) Both A & B
Physical or logical arrangement of network is called Topology. In networking, the physical or logical arrangement of network devices is called topology. The most common types of topologies are bus, star, ring and mesh. Each type has its own advantages and disadvantages. The bus topology is the simplest and most common type of topology. In this type of topology, all devices are connected to a single cable. The main advantage of this topology is that it is easy to implement and requires less cable than other topologies. The disadvantage of this topology is that if the cable fails, the entire network fails.
The star topology is the most popular type of topology. In this type of topology, all devices are connected to a central device called a hub or switch. The advantage of this topology is that it is easy to expand and provides good performance.
What makes fiber preferable to copper cabling for interconnecting buildings (Choose 3 of them)
a) easily terminated
b) greater distances per cable run
c) lower installation cost
d) limited susceptibility to EMI/RFI
e) greater bandwidth potential
f) durable connections
The Correct Answer for the given question is option b, d and e. Fiber optic cabling is becoming the preferred choice for interconnecting buildings as it offers a number of advantages over copper cabling. Fiber optics can carry signals much farther than copper without losing data integrity, and it is immune to electromagnetic interference (EMI). Fiber also has much higher bandwidth potential than copper, meaning that more data can be carried over a single fiber optic cable than a copper cable of the same size. Finally, fiber optics are less expensive to install and maintain than copper cabling.
