Topic 1.3 Part 2 - Wired and Wireless Networks Flashcards
What is a wireless network?
A wireless network is a network in which devices are connected to each other without the use of physical cables, using radio waves or infrared signals.
What is Wi-Fi?
Wi-Fi is a popular wireless technology that allows devices to connect to a network using radio waves, providing mobility and convenience.
What is a wireless router?
A wireless router is a device that combines a router with a Wi-Fi access point, allowing both wired and wireless devices to connect to a network.
What is a wireless access point (AP)?
A wireless access point is a device that allows wireless devices to connect to a wired network, often used to expand Wi-Fi coverage.
What is a SSID (Service Set Identifier)?
An SSID is a unique name for a wireless network, which wireless devices use to identify and connect to the network.
What is WPA (Wi-Fi Protected Access)?
WPA is a security protocol that encrypts data on a wireless network to protect it from unauthorized access.
What is a Wi-Fi hotspot?
A Wi-Fi hotspot is a location that provides wireless Internet access, often found in public places like cafes and airports.
What is a wireless network adapter?
A wireless network adapter is a device that allows a computer or device to connect to a wireless network.
What is a wireless network card?
A wireless network card is a hardware component inside a computer that enables it to connect to Wi-Fi networks.
What is 5G in wireless networks?
5G is the fifth generation of wireless technology, offering higher data speeds and reduced latency for mobile devices.
What is a wired network?
A wired network is a network in which devices are connected to each other using physical cables or wires.
What is Ethernet?
Ethernet is a widely used wired networking technology that uses twisted-pair or fiber-optic cables to connect devices.
What is a network cable?
A network cable is a physical cable used to transmit data between devices in a wired network, such as Ethernet cables.
What is a router in a wired network?
A router in a wired network is a device that directs data between devices on the same network and between different networks.
What is Ethernet cabling?
Ethernet cabling is a common type of network cabling that includes Cat 5e, Cat 6, and Cat 7 cables, used in wired networks.
What is fiber-optic cabling?
Fiber-optic cabling uses glass or plastic fibers to transmit data as light signals, offering high-speed and long-distance connections.
What is PoE (Power over Ethernet)?
PoE is a technology that allows both data and power to be delivered over Ethernet cables, commonly used for devices like IP cameras.
What is a patch cable?
A patch cable is a short cable used to connect devices in a local area network, often used to connect a computer to a wall jack.
What is a network hub?
A network hub is a simple device used to connect multiple Ethernet devices in a star topology.
What are the advantages of wired networks?
Advantages of wired networks include reliability, security, and consistent data speeds.
What are the advantages of wireless networks?
Advantages of wireless networks include mobility, flexibility, and ease of installation
What are the disadvantages of wired networks?
Disadvantages of wired networks include cable management, limited mobility, and higher installation costs.
What are the disadvantages of wireless networks?
Disadvantages of wireless networks include potential interference, security concerns, and slower data speeds compared to wired networks.
What is the role of wireless bridges in networking?
Wireless bridges connect two separate wired networks using wireless technology, often used to extend network coverage.
