Mbsa Basic Computer Network Training Quiz 1

Yes, two connected computers can be considered a network. A network is a collection of interconnected devices that can communicate and share resources. Even if there are only two computers connected, they can still form a network as long as they are able to exchange information and establish a connection between them.

A LAN stands for Local Area Network. It is a computer network that connects devices within a limited geographical area, such as a home, office building, or campus. LANs are typically used to share resources, such as printers and files, and to facilitate communication between devices. They are characterized by high data transfer rates, low latency, and private ownership.

A Wide Area Network (WAN) is a type of computer network that spans a large geographical area, typically connecting multiple local area networks (LANs) together. It allows for the transmission of data, voice, and video over long distances, often using leased lines or satellite links. WANs are commonly used by businesses and organizations to connect their offices located in different cities or countries. They provide a secure and reliable means of communication between remote locations, enabling employees to access shared resources and collaborate effectively.

The correct answer is "popular technology that allows an electronic device to exchange data wirelessly." Wi-Fi, short for wireless fidelity, is a widely used technology that enables devices such as smartphones, laptops, and tablets to connect to the internet and exchange data without the need for physical cables. It uses radio waves to transmit data over a wireless network, providing convenience and flexibility for users to access the internet and communicate with other devices.

The term "Wide" in the given options suggests that the correct answer is "Wide Area Network." A Wide Area Network (WAN) is a type of computer network that covers a large geographical area, such as cities, countries, or even continents. This network allows the connection of multiple local area networks (LANs) across a wide area, enabling communication and data transfer between different locations. Therefore, the option "Wide" accurately describes the network that covers a large geographical area.

A Wide Area Network (WAN) is the correct answer because it refers to a network that spans a large geographical area, typically connecting multiple smaller networks together. The internet is a prime example of a WAN, as it connects computers and devices from all over the world, allowing them to communicate and share information.

A firewall is a security measure that is used to prevent unauthorized access to a computer network. It acts as a barrier between the internal network and external networks, such as the internet, and monitors incoming and outgoing network traffic. By doing so, it can identify and block any unwanted network connections that may be attempting to gain access to the network, thus protecting the network from potential security threats and unauthorized access.

VoIP stands for Voice over Internet Protocol, which is a technology that allows users to make telephone calls over the internet. It converts voice signals into digital data packets and transmits them over an IP network, enabling communication between individuals using different devices and platforms. This technology has revolutionized the telecommunications industry by providing cost-effective and efficient communication solutions. Skynet, Telenet, and Intertel are not specific technologies related to making telephone calls over the internet, making VoIP the correct answer.

A MAC address is a unique serial number assigned to every network interface card (NIC) in a computer or other network device. It is used to identify the device on a network and is composed of six pairs of hexadecimal digits separated by colons or hyphens. Unlike an IP address, which can change depending on the network the device is connected to, a MAC address is permanent and cannot be changed. Therefore, the MAC address is the correct answer to the question.

A computer must have an IP address when connecting to a Wi-Fi hotspot, connecting to a home network router, and communicating with another computer using TCP. In order to connect to a Wi-Fi hotspot or a home network router, the computer needs an IP address to identify itself on the network and establish a connection. Similarly, when communicating with another computer using TCP, IP addresses are used to route the data packets between the sender and receiver. Playing media from the hard drive does not require an IP address as it is a local operation within the computer.

An IP address is a numeric quantity that identifies a network adapter to other devices on the network. It is a unique identifier assigned to each device connected to a network, allowing them to communicate and exchange data with other devices on the same network. The IP address helps in routing the data packets to the correct destination and establishing connections between devices. It does not indicate the physical location of a computer or the manufacturer of a computer.
