- Q1What is the main difference between WiFi and cellular networks?Cellular networks use cellular towers to connect devices, while WiFi networks use routers to create a local area network (LAN)WiFi networks do require a subscription, while cellular networks do notWiFi networks use cellular towers to connect devices, while cellular networks use routers to create a LANCellular networks are always faster than WiFi networks30s
- Q2Which of the following is a characteristic of WiFi networks compared to cellular networks?WiFi networks have faster data speeds than cellular networksWiFi networks have limited range and coverage compared to cellular networksWiFi networks require a subscription to access, unlike cellular networksWiFi networks use cellular towers to connect devices, similar to cellular networks30s
- Q3What is a common feature of both WiFi and cellular networks?Both WiFi and cellular networks require physical cables for connectionBoth WiFi and cellular networks allow devices to connect to the internet wirelesslyWiFi networks are only used for voice calls, while cellular networks allow internet browsingWiFi networks are restricted to specific locations, while cellular networks provide wide coverage30s
- Q4What is a key difference in the way WiFi and cellular networks handle connectivity to the internet?Cellular networks rely on passwords for internet connectivity, similar to WiFi networksWiFi and cellular networks both authenticate users through a username and passwordWiFi networks do not require any form of authentication for accessWiFi networks typically require a password for access, while cellular networks authenticate through a SIM card or subscription service30s
- Q5Which network type is more susceptible to interference from external factors like walls and distance: WiFi or cellular?Both WiFi and cellular networks are equally susceptible to interference from external factorsCellular networks are more affected by physical barriers like walls and distance compared to WiFi networksWiFi networks are more affected by physical barriers like walls and distance compared to cellular networksNeither WiFi nor cellular networks are affected by physical barriers or distance30s
- Q6What is a key difference in the security measures between WiFi and cellular networks?WiFi networks rely solely on cellular carriers for network securityBoth WiFi and cellular networks use the same encryption protocols for data transmissionCellular networks do not have any security measures in place for data transmissionWiFi networks often use encryption protocols to secure data transmission, while cellular networks rely on network security provided by cellular carriers30s
- Q7In terms of coverage, how does WiFi differ from cellular networks?WiFi networks and cellular networks have the same coverage rangeWiFi networks have a limited range and coverage area compared to cellular networksWiFi networks can cover long distances better than cellular networksWiFi networks have a wider coverage area than cellular networks30s
- Q8What does IMEI stand for?Infrared Mobile Error IdentificationInternational Mobile Equipment IdentityInternet Mobile Energy IndicatorInternal Mobile Encryption Interface30s
- Q9How many digits are there in an IMEI number?2520101530s
- Q10Why is the IMEI number important for mobile phones?It enhances the battery life of the deviceIt is used to uniquely identify a mobile deviceIt connects the phone to Wi-Fi networksIt determines the color of the phone30s
- Q11How does the IMEI number differ from the IMSI number in a mobile phone?IMEI is a 10-digit code, while IMSI is a 15-digit codeIMEI identifies the device, while IMSI identifies the subscriber's SIM cardIMEI is used for GPS tracking, while IMSI is used for Bluetooth connectivityIMEI identifies the network provider, while IMSI identifies the device30s
- Q12Can the IMEI number of a mobile phone be changed?NoYesMaybeSometimes30s
- Q13What does SIM stand for in sim card?Subscriber Identity ModuleSystem Identification ModuleSecurity Information ModuleService Indicator Module30s
- Q14What is the purpose of the IMSI stored on a sim card?Connects to Bluetooth devicesEncrypts voice callsManages contact informationIdentifies the subscriber within the network30s
