(a)  Which laptop will likely boot faster?

(b) Calculate the maximum number of bytes of data that can be stored in the hard disk of:

  1. Laptop A;
  2. Laptop B.

(c) State the type of operating system installed in both laptop A and laptop B.

(d) State one function of the Bluetooth in laptop A.

(e) A certain salesperson makes a long trip by road as part of his job and also uses the computer for live communications with his customers.

  1. Which of the laptop is more suitable for the salesperson?
  2. Name three features of the laptop chosen in 5(e)(i) that makes it more suitable than the other.
  3. Give one reason for choosing each of the features in 5(e)(ii).

 

Observation

  

 The expected answer is:
(a)     Laptop likely to boot faster
- Laptop A                                                                                                              
(b)  Calculation of maximum number of bytes of data can be stored in the hard disk of:
(i)       Laptop A = 500GB                      
= 500×1024×1024×1024 bytes     
=536,870,912,000 bytes                           

  • Laptop B = 320 GB

                = 320×1024×1024×1024 bytes
= 343, 597, 383,680 bytes
(c)               Type of operating system installed in Laptop  A and Laptop B

  • Graphical user interface/Multi-user OS/ Windows OS                                                                                     

(d)         Functions of Bluetooth in Laptop A
