A Brief Trivia On Computer Networking!

2.

What is the most common adapter or connector used to connect a computer to a wired network?

RG58
RG6
RJ45
RJ8

Correct Answer

A. RJ45

Explanation

The most common adapter or connector used to connect a computer to a wired network is RJ45. RJ45 is a standard connector that is widely used for Ethernet connections. It has eight pins and is commonly used for connecting computers, routers, switches, and other network devices to a local area network (LAN). RJ45 connectors are easy to use, durable, and provide a reliable connection for high-speed data transmission.

Which of the following does a switch use for increased performance?

Simplex
Half duplex
Full duplex
Sliding duplex

Correct Answer

A. Full duplex

Explanation

A switch uses full duplex for increased performance. Full duplex allows simultaneous two-way communication between devices, enabling data to be sent and received at the same time. This eliminates the need for devices to wait for their turn to transmit data, resulting in faster and more efficient data transfer. In contrast, simplex only allows data to be transmitted in one direction, half duplex allows data transmission in both directions but not simultaneously, and sliding duplex is not a recognized term in networking.

What do you use to create VLANs?

Router
Switch
Firewall
Proxy Server

Correct Answer

A. Switch

Explanation

Switches are used to create VLANs. VLANs, or Virtual Local Area Networks, are used to segment a network into smaller logical networks. Switches are capable of assigning ports to specific VLANs, allowing for the separation of traffic and the creation of isolated networks within a larger network infrastructure. Routers, firewalls, and proxy servers may be used in conjunction with switches to provide additional network functionality, but switches are specifically designed for VLAN creation.

What standard describes CSMA/CD?

801.2
802.3
802.5
802.11

Correct Answer

A. 802.3

Explanation

The correct answer is 802.3. This standard describes CSMA/CD, which stands for Carrier Sense Multiple Access with Collision Detection. CSMA/CD is a protocol used in Ethernet networks to regulate access to the network medium and handle collisions when multiple devices try to transmit data simultaneously. The 802.3 standard specifies the physical layer and the data link layer of the Ethernet protocol, providing guidelines for the implementation and operation of Ethernet networks.

What mechanism do wireless networks use to access the network?

CSMA/CD
CSMA/CA
Token passing
Polling

Correct Answer

A. CSMA/CA

Explanation

Wireless networks use the CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism to access the network. CSMA/CA is a protocol that helps avoid collisions in wireless networks by requiring devices to listen and check if the channel is clear before transmitting data. This mechanism helps prevent multiple devices from transmitting at the same time, reducing the chances of collisions and improving network efficiency.

What type of server does Active Director run on?

File server
Print server
Database server
Network controller

Correct Answer

A. Network controller

Explanation

Active Directory is a directory service developed by Microsoft that is used to manage and organize resources in a network. It runs on a network controller server, which is responsible for managing and controlling network resources such as user accounts, security policies, and network devices. The network controller server acts as the central point for managing and coordinating network operations within an Active Directory environment. Therefore, the correct answer is network controller.

What model promises the most processing power?

Centralized computing
Distributive computing
Switching computing
Dumb computing

Correct Answer

A. Distributive computing

Explanation

Distributive computing promises the most processing power because it involves the use of multiple computers or processors working together to solve a problem or complete a task. This allows for parallel processing, where each computer or processor can handle a portion of the workload, resulting in faster and more efficient processing. In contrast, centralized computing relies on a single computer or server to handle all the processing, which may limit the overall processing power. Switching computing and dumb computing do not specifically address the concept of processing power in the same way as distributive computing.

What type of communication is sent to a single designated host?

Unicast
Broadcast
Multicast
Anycast

Correct Answer

A. Unicast

Explanation

Unicast communication is sent to a single designated host. In this type of communication, a message is transmitted from one sender to one specific receiver. It is a point-to-point communication where the sender and receiver are directly connected. Unicast is commonly used in most communication networks, such as email, telephone calls, and web browsing, where the information is intended for a specific recipient.

A ___________ is a single computer or device that connects to a TCP/IP network.

Host
Node
Access point
Laptop

Correct Answer

A. Host

Explanation

A host is a single computer or device that connects to a TCP/IP network. It acts as the source or destination of data packets within the network. The term "host" is often used to refer to any computer or device that is connected to a network and provides services or resources to other devices on the network.

What is the central device used in wireless LANs?

Wireless Access Point
CSA/CDM connector
Wireless Switch
MDU

Correct Answer

A. Wireless Access Point

Explanation

A wireless access point is the central device used in wireless LANs. It acts as a bridge between wireless devices and a wired network. It allows devices to connect to the network without the need for physical cables. The access point receives and transmits wireless signals, enabling communication between devices within its range. It also provides security features such as encryption and authentication to protect the network. Overall, a wireless access point is essential for establishing a wireless network and enabling connectivity for wireless devices.

What command do you use to test the TCP/IP stack on a computer?

Ping localhost
Ping 127.0.0.1
Ping loopback
Ipconfig/renew

Correct Answer

A. Ping localhost

Explanation

The command "Ping localhost" is used to test the TCP/IP stack on a computer. The "Ping" command sends a small packet of data to the specified destination and waits for a response. In this case, "localhost" refers to the loopback address 127.0.0.1, which is the IP address assigned to the local machine. By pinging localhost, we can verify if the TCP/IP stack is functioning properly on the computer.
