(16 cards)
What type of waves do mobile phones use to transmit voice signals?
Radio waves.
What does the “G” in 3G, 4G, and 5G stand for?
Generation.
What wireless technology allows devices to communicate over short distances?
Bluetooth.
Which wireless technology enables close-proximity data exchange?
NFC (Near Field Communication)
What is the primary use of GPS in mobile devices?
To determine the device’s location using satellite signals.
What are the four main components of a Local Area Network (LAN)?
Hosts, peripherals, network devices, and network media.
What is an example of a host in a network?
A personal computer or network printer.
Why do peripherals not directly communicate on the network?
They rely on a connected host to send and receive data.
Give two examples of network devices.
Routers and switches.
What is the purpose of network media?
To provide wired or wireless connections between devices.
What are the three components required for IP configuration on a device?
IP address, subnet mask, and default gateway.
What is the difference between manual and automatic IP addressing?
Manual addressing requires a network administrator to manually assign an IP address, which is called a static IP.
Automatic addressing allows a DHCP server to assign IP addresses dynamically from a pool.
What is a static IP address?
A manually assigned IP address that does not change unless modified by an administrator.
What is DHCP, and how does it work?
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices on a network.
A device requests an IP address from a DHCP server, which then assigns one from a pool of available addresses.
What are the two types of network topology representations?
Physical topology – Shows the actual placement of devices and cables.
Logical topology – Shows how data flows through the network.
Why is network documentation important?
Helps with network troubleshooting and management.
Makes training new IT staff easier.
Ensures consistency in device naming and IP address assignments.
