Wireless network technologies Flashcards
what are some examples of these
Wi-Fi, cellular networks, satellite networks and 5G
what is an access point
A networking device that enables other Wi-Fi devices to connect to a wired network. They receive wireless signals from devices, such as smartphones and laptops, and then transmit those signals to the Internet.
what is bandwidth
The amount of data that can be sent across the network is referred to as bandwidth.**
Bandwidth can be considered the number of lanes on a highway in a wireless network. Similar to a highway, a wireless network can become congested if there is insufficient bandwidth to accommodate the amount of traffic (data) trying to travel on it.
The more bandwidth a network has, the more data can travel simultaneously, resulting in a faster Internet speed
what connection speed
The speed at which data is exchanged between a device and the Internet. Connection speed can be considered the speed limit on a highway in wireless networks. Like a speed limit, connection speed determines how fast data travels on a wireless network.
what is blockchain
Blockchain is a dynamic set of documents, known as blocks, that are connected together using encryption.
Blockchain can be thought of as the traffic cop of the Internet in the world of wireless networks. Just like a traffic cop ensures traffic flows smoothly and safely on the road, blockchain ensures that data on a wireless network is secure and tamper-proof.
what is a wireless network
Wireless network:Acollection of devices that send and receive information across radio frequencies.
what is a Local Area Network (LAN)
a computer network that connects within a specific geographic area, such as a home, school, laboratory, university campus, or office building.
what is a Wide Area Network (WAN)
a sort of network that spans a greater geographical region, therefore the Internet may be a WAN. In the case of the internet, cables are used to transmit the majority of information since they are usually quickest, more dependable, and much less vulnerable to disruption.
what is a WiFi network
a network that typically covers small to medium-sized areas, such as offices or residential premises. The range of WiFi can be expanded by using transmitters.
what is Bluetooth
Bluetooth uses radio waves to communicate between devices across short distances. The majority of its uses are in remote controls, minimal data transmission, and mobile phone-to-device communication.
what is Cellular Communication
a scenario in which a mobile phone, a smartphone, a tablet with a SIM card, or a laptop computer links to a cellular tower to provide internet access while on the move. This includes:
what is data security
Data security is about protecting against cyberattacks, data breaches and other malicious activities on the Internet.
