Networking 101 Questions: Quiz!

A computer network refers to a system where multiple computers or devices are connected to each other, allowing them to communicate and share resources. This interconnectedness enables data transmission, file sharing, and collaboration among the devices within the network. Therefore, the statement that "A computer network is a network of interconnected computers or devices" is true, as it accurately describes the fundamental concept of a computer network.

The given question asks for a term that describes various forms of efficient interaction that can take place over networks. Among the options provided, only "communication" fits this description. Email, instant messaging, chat rooms, and videoconferencing are all examples of communication methods that can occur efficiently through networks.

A Wide Area Network (WAN) is a network that covers a large geographical area and uses many types of communications channels. Unlike a Local Area Network (LAN) which is limited to a small area, a WAN can span across cities, countries, or even continents. It connects multiple LANs and allows for the transmission of data, voice, and video over various types of communication channels such as leased lines, satellite links, or optical fibers. WANs are commonly used by organizations to connect their branch offices or to provide internet connectivity to remote locations.

WLAN stands for Wireless Local Area Network. It is a type of wireless network that allows devices to connect and communicate with each other within a limited area, such as a home, office, or campus. This technology enables wireless access to the internet and facilitates the sharing of data and resources among connected devices. The other options, Wireless Large Area Network, Western Local Address Network, and World-Local Address Network, are not correct definitions for WLAN.

Internet peer-to-peer networking enables users with the same networking software to exchange files directly from each other's hard disks. This means that users can share files with each other without the need for a central server. Instead, they can connect directly to each other's devices and transfer files back and forth. This allows for faster and more efficient file sharing between users on the network.

A LAN is only one type of network. Computers/devices need to be connected not just in an organization. A wireless link is only one type of connection.

A firewall is a security measure that can be implemented through hardware and/or software to restrict access to data on a network. It acts as a barrier between a trusted internal network and an untrusted external network, monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. By filtering and blocking unauthorized or potentially harmful connections, a firewall helps to protect the network from unauthorized access, malware, and other cyber threats.

The correct answer is "all of the above" because to connect to the internet, you can use any of the mentioned options: dial-up connection, DSL connection, cable lines connection, or satellite connection. Each of these options provides a different method of accessing the internet, allowing users to choose the one that best suits their needs and availability in their area.

FTP stands for File Transfer Protocol. It is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the internet. FTP allows users to upload, download, and manage files on a remote server. It provides a simple and efficient way to transfer files between computers and is widely used for website maintenance, software updates, and file sharing.

Switches on a network are hardware devices that manage network data traffic. They are responsible for receiving data packets and forwarding them to the appropriate destination. Switches use MAC addresses to determine the destination of the packets and create a direct connection between the sending and receiving devices. This allows for efficient and secure communication within a network. Unlike software packages or network interface cards, switches are physical devices that provide the necessary infrastructure for data transfer. Megabit data devices are not a relevant concept in this context.

WAN (Wide Area Network) has the widest coverage among the given options. LAN (Local Area Network) has a limited coverage area typically within a building or a campus, while MAN (Metropolitan Area Network) covers a larger geographical area such as a city. WAN, on the other hand, covers the widest area, often spanning across multiple cities or even countries, making it the most suitable option for wide coverage.

Fibre-optic cable is capable of the fastest rate of data transmission compared to the other options. This is because it uses light signals to transmit data, which can travel at a much higher speed than electrical signals used in other transmission media. Additionally, fibre-optic cables have a higher bandwidth capacity, allowing for the transmission of larger amounts of data at faster rates.

A client is any component on a network that receives data from other components. This means that the client is the entity that requests and consumes data or services from a server or another component. It can be a computer, a mobile device, or any other device connected to the network that relies on data provided by other components. The client initiates communication and sends requests to the server or other components to retrieve the required information.

The best solution for setting up a network in a building where drilling holes through walls is not possible would be to use a WAP (Wireless Access Point). This is because a WAP allows for wireless connectivity, eliminating the need for physical cables and drilling. By using a WAP, devices can connect to the network wirelessly, providing a convenient and flexible solution for networking in a building without the need for drilling.

The answer is Network Interface Card

A LAN (Local Area Network) is a network that connects computers and devices within a limited area, such as a home, office, or school. It allows users to share resources such as files, application programs, printers, and other software/hardware. This means that users connected to the LAN can access and use these shared resources, making collaboration and communication more efficient. The transfer of money via electronic funds transfer and public transportation are unrelated to the concept of a LAN, so they are not valid options.

To restrict unauthorized access to a Wireless Network, it is important to consider not broadcasting the network name. By hiding the network name (SSID), it becomes more difficult for potential attackers to discover and target the network. Additionally, only allowing access to specified devices adds another layer of security. By configuring the network to only permit connections from specific devices, unauthorized devices are prevented from accessing the network. Finally, using data encryption, such as WPA2, ensures that the data transmitted over the network is encrypted and cannot be easily intercepted or accessed by unauthorized users. Therefore, considering all three measures - not broadcasting the network name, only allowing access to specified devices, and using data encryption - helps to enhance the security of a wireless network.

A NIC, or Network Interface Card, is a material or technology used to establish the communications channel in a computer and attaches to the cable or wireless technology used to connect the devices in a network. It allows the computer to connect to a network and communicate with other devices.

The given question asks for the option that is NOT a type of network topology. A network topology refers to the arrangement of nodes and connections in a network. The options "STAR," "RING," "BUS," and "MESH" are all types of network topologies. However, "TREE" is not a type of network topology. A tree structure is a hierarchical arrangement where nodes are connected in a branching pattern resembling a tree. Therefore, the correct answer is TREE.

A server is a combination of hardware and software that is specifically designed to provide services to clients. This can include tasks such as storing and managing data, hosting websites or applications, and facilitating network connections. Servers are typically installed in computers and allow access to a network through Ethernet or wireless connections. They act as a central hub that receives data from other components on the network and processes it to fulfill the requests of clients.

A node refers to anything physically connected to a network, including workstations, servers, and connectors. It encompasses all devices that are part of the network and can transmit or receive data.

The correct answer is "None of the Above" because all the options listed (Cables, Fiber Optics, and Radio Waves) are examples of communications media. Cables are physical wires used to transmit data, fiber optics use light signals to transmit data, and radio waves are electromagnetic waves used for wireless communication. Therefore, none of the options provided are not examples of communications media.

SPAM refers to unsolicited email or web page material, usually advertisements. It is content that is sent to users without their consent or request. This can include promotional messages, offers, or other forms of advertising that are not relevant or desired by the recipient. It is important to be cautious of SPAM as it can be annoying, intrusive, and potentially contain malicious content.

The correct answer is a convergence of technologies that has resulted in a device also performing the functions of a different device. This answer accurately describes a smartphone as a device that combines various technologies, such as telecommunication, computing, and multimedia, to perform functions that were traditionally done by separate devices like phones, cameras, and music players.

A peer-to-peer network is the correct answer because it refers to a network where computers are connected and share resources such as files and printers without the need for a central server. In this type of network, each computer can act as both a client and a server, allowing for a decentralized system where all computers have equal status and can directly communicate with each other. This setup is commonly used in small networks where simplicity and cost-effectiveness are prioritized over centralized control.

The answer is protocol

The second option, "www.yahoo.com," is a typical web address for the Yahoo search engine. The third option, "http://192.168.0.1," is an example of an IP address used to access a specific device or network. Therefore, none of the above options are NOT examples of web addresses.

The correct answer includes "Wireless Card" and "Ethernet Card" because both are common examples of Network Interface Cards (NICs). A NIC is a hardware component that allows a computer to connect to a network, enabling communication between devices. A wireless card is used to connect to a network wirelessly, while an Ethernet card is used for wired connections. Both cards provide the necessary interface for data transmission and reception, making them common examples of NICs.

The correct answer is "allowing restricted access to company information and supporting workers working in groups using Internet and web technologies." An intranet is a private network that is used within an organization to share information, collaborate, and communicate. It is accessible only to authorized users and provides a secure environment for employees to access company resources and work together using internet and web technologies.

A client-server network consists of a server computer and other computers that it controls. In this type of network, the server computer provides resources, such as files, printers, and internet access, to the client computers. The client computers, also known as client devices, connect to the server to request and receive these resources. The server manages and controls the network, while the client computers utilize the resources provided by the server. This type of network architecture allows for centralized control and efficient sharing of resources among multiple computers.

Networking computers can improve efficiency because when resources such as printers, scanners, and storage devices are shared among multiple computers, it eliminates the need for each computer to have its own individual resources. This not only reduces costs associated with purchasing and maintaining individual resources for each computer but also allows for better utilization of these resources. Additionally, sharing resources through a network promotes collaboration and facilitates easy access to shared files and data, further enhancing efficiency in a work environment.

A dial-up modem is a device that converts analogue signals into digital signals and vice versa. It allows computers to connect to the internet using a telephone line. The modem converts the digital data from the computer into analogue signals that can be transmitted over the phone line, and then converts the analogue signals received from the phone line back into digital data that the computer can understand. This conversion is necessary because telephone lines transmit data in analogue form, while computers process and communicate data in digital form.
