D-link Networks Technical Quiz

A WAN, or Wide Area Network, is a type of computer network that spans a large geographical area, such as multiple buildings, cities, or even countries. It is used to connect different local area networks (LANs) together, allowing computers and devices in different locations to communicate with each other. A WAN typically uses public communication channels, such as telephone lines or satellite links, to transmit data over long distances. This enables organizations to establish a secure and reliable network infrastructure for their operations across a wide area.

An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for the device and allows it to communicate with other devices on the internet. Therefore, the correct answer is "A number that is assigned to every device on the internet."

The correct answer is RJ-45. RJ-45 is the type of connector found on a Category 5 Ethernet Cable. This connector is commonly used for Ethernet networking and is designed to connect computers, routers, switches, and other network devices together. It has 8 pins and is larger than the RJ-11 connector, which is used for telephone connections. The RJ-45 connector is also different from the BNC and RF connectors, which are used for coaxial cable connections.

A home network router enables safe sharing of resources among network devices in the home. This means that multiple devices such as computers, smartphones, and smart home devices can connect to the router and share resources such as internet access, printers, and files securely within the home network. The router acts as a central hub, allowing devices to communicate with each other and providing a secure barrier between the home network and the internet, protecting the devices from external threats.

A home computer network is called a LAN, which stands for Local Area Network. This type of network is designed to connect devices within a limited area, such as a home or office, allowing them to share resources and communicate with each other. LANs are typically used for tasks like sharing files, printers, and internet connections among multiple devices in a localized environment.

A LAN refers to a Local Area Network, which is a network that connects computers and devices within a limited area such as a building or a campus. It allows for the sharing of resources such as files, printers, and internet connections among the connected devices. LANs are commonly used in homes, offices, and schools to facilitate communication and data transfer between devices in a localized area.

Port 80 is used for HTTP traffic. HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting and receiving web pages and other resources on the internet. Port 80 is the default port for HTTP, and it is used by web browsers to communicate with web servers. When a user enters a website address in their browser, the browser sends a request to the web server on port 80, and the server responds by sending the requested web page back to the browser.

A router is a device that allows multiple computers to share a single internet connection. It acts as a central hub for connecting devices to the internet and provides a way for data to be transmitted between them. By connecting multiple computers to a router, users can access the internet simultaneously and share resources such as files and printers. The router also helps in directing network traffic efficiently by choosing the best path for data transmission.

Yes, a network card is required to get online to the internet. A network card, also known as a network interface card (NIC), is a hardware component that allows a computer to connect to a network. It provides the necessary interface between the computer and the network cables, enabling communication with other devices and access to the internet. Without a network card, the computer would not have the capability to connect to the internet.

Windows 7 is the newest Microsoft operating system among the options given. Windows Vista was released before Windows 7, Windows XP was released even earlier, and Windows 98 and Windows 3.1 are much older operating systems. Therefore, Windows 7 is the correct answer as the newest Microsoft operating system.

Every NIC (Network Interface Card) has a unique serial number called a MAC Address. This address is assigned by the manufacturer and is used to identify a device on a network. Unlike an IP address, which can change based on network configurations, the MAC address remains constant for the lifetime of the NIC. It is used for communication within a local network, allowing devices to send and receive data packets.

A computer must have an IP address when connecting to a Wi-Fi hotspot because the IP address is used to identify and route data packets to and from the computer. Similarly, when connecting to a home network router, an IP address is necessary for the computer to be recognized and communicate within the network. Additionally, when communicating with another computer using TCP (Transmission Control Protocol), IP addresses are essential for establishing a connection and facilitating data transfer. Therefore, all of the given options require a computer to have an IP address.

802.11r is not a wireless standard because it is actually a wireless roaming standard. It is specifically designed to improve the handoff between access points in a wireless network, allowing for seamless and uninterrupted connectivity as a user moves from one access point to another. The other options, 802.11a, 802.11g, and 802.11n, are all wireless standards that define the specifications for wireless local area networks (WLANs) and the transmission of data over them.

A switch is a device used to expand an existing network by connecting multiple devices together. It allows these devices to communicate with each other and share resources such as files and printers. Unlike a hub, a switch can intelligently direct network traffic to the appropriate device, improving network performance and efficiency. Switches are commonly used in both home and business networks to create a larger and more interconnected network infrastructure.

Category 5 cable is used to connect computers into a network. It is a type of twisted pair cable that supports data transfer rates of up to 1000 Mbps. It is commonly used in Ethernet networks and can be used for both voice and data transmission. Category 5 cable is known for its reliable performance and is widely used in homes, offices, and data centers for networking purposes.

WPA2 is the most secure security method among the options given. WPA2, which stands for Wi-Fi Protected Access 2, is an encryption protocol that provides stronger security compared to WPA and WEP. It uses the Advanced Encryption Standard (AES) algorithm, which is considered highly secure. WPA2 also offers better protection against unauthorized access and attacks, making it the preferred choice for securing wireless networks. MAC Filtering, on the other hand, is a method that allows or denies network access based on the MAC address of devices, but it is not as secure as WPA2 encryption.

DSL, dialup, cable, and satellite are all forms of Internet service. DSL (Digital Subscriber Line) uses existing telephone lines to provide high-speed Internet access. Dialup uses a modem and a telephone line to establish a connection to the Internet. Cable Internet utilizes cable television infrastructure to provide high-speed Internet access. Satellite Internet uses satellite communication to provide Internet access in areas where traditional wired connections are not available. Therefore, all of the mentioned options are valid forms of Internet service.

The maximum speed of 802.11g is 54Mbps. This is because 802.11g is a wireless networking standard that operates on the 2.4GHz frequency band and uses Orthogonal Frequency Division Multiplexing (OFDM) modulation. It has a maximum data rate of 54Mbps, which is significantly faster than the previous 802.11b standard that had a maximum data rate of 11Mbps. However, it is slower than the subsequent 802.11n and 802.11ac standards that offer higher speeds of up to 300Mbps and beyond.

The correct answer is WEP, WPA, and WPA2. These are all types of wireless encryption (security) protocols used to protect wireless networks from unauthorized access. WEP (Wired Equivalent Privacy) is the oldest and least secure, while WPA (Wi-Fi Protected Access) and WPA2 are more advanced and provide stronger security measures. WAP (Wireless Application Protocol) and WPS (Wi-Fi Protected Setup) are not encryption types, but rather standards and methods used for wireless communication and network setup, respectively.
