GSM Phone Maintenance and Repair Paper 2, WASSCE (SC), 2018

Question 6

 

  1. Define the following terms in relation to mobile phones:
  2. Freezing
  3. Locking
  1. List two differences between locking and blocking.

Candidates performed poorly on this question as most of them could neither define freezing appropriately nor differentiate between locking and blocking.

Observation

The expected answers are:

(a) (i) Freezing:   This is a condition in which a mobile phone keypad / touchscreen  is not responding to any operation carried out on it as a result of corrupt memory / application, virus attack or insufficient memory.                                                          
     (ii) Locking: This is a condition in which a mobile phone is protected against  unauthorised user or another network provider.                                                                                                              
          (b)    Differences between locking and blocking


Locking

Blocking

It is done on the phone

It is done on the SIM card

It can be unlocked with a computer or using codes / combination of keys

It is unblocked by contacting service provider

It is deliberately done by user or service provider

It is as a result of user error
