Question 1, May 2019, Pearson Edexcel International GCSE (9-1) Information and Communication Technology, Paper-1

Kiki buys a smartphone.

(a) The smartphone uses a sensor that detects movement of the device.

One way in which the smartphone uses data from the sensor is to switch itself off if dropped.

Give two other ways in which the smartphone could use data from the sensor. (2)

1 The smartphone could use data from the sensor, accelerometer, to detect 'tilt' in a game.

2 The smartphone could use data from the sensor, pedometer, to track the steps done by a user.

(b) Smartphones can be connected using wired or wireless methods. (2)

(i) Give two advantages to Kiki of using a wired method to connect to the smartphone. (2)

1 Using a wired connection method to connect to the smartphone is more stable as it is less affected by interference (e.g. dropped packets, loss of data).

2 Wired connection is usually faster as it is connected directly to the smartphone without any obstacles (e.g. walls).

(ii) Give two advantages to Kiki of using a wireless method to connect to the smartphone. (2)

1 Using a wireless connection method to connect to the smartphone is more comfortable as it is portable within signal range.

2 Wireless connection is usually cheaper as there is no need to buy cables.

(c) The smartphone uses a SIM card.
Which one of these is a type of connectivity that the SIM card provides? (1)
B Bluetooth
C Infrared
D 4G
A WLAN

D 4G

(d) Kiki meets her friend, Zara.

(i) Draw a diagram to show hoe Kiki's smartphone can be used to provide Zara's tablet computer with an Internet connection.

Label each component and the connectivity you use in your diagram. (4)

(ii) Explain why sharing an Internet connection would affect the bandwidth available to Kiki's smartphone. (2)

The speed at which devices can transfer data depends on the bandwidth of the connection. Sharing an Internet connection would affect the bandwidth available to Kiki's smartphone because it is fixed in Kiki's smartphone and it must be divided between each device while Kiki share it with Zara.

(e) Kiki's smartphone and Zara's tablet computer share a lot of the same functionality.
State the term used to describe this. (1)

The term used to describe this is convergence.

(f) The smartphone has a 4 GHz CPU.
Describe the function of a CPU. (2)

The CPU executes a sequence of stored instructions called a program. This program will take inputs from an input device, process the input in some way and output the results to an output device.

(g) The smartphone uses application software.
Describe the purpose of application software. (2)

The purpose of application software (apps) is to allow users to produce digital product, such as a presentation or image, or carry out specific tasks that are not related to the operating system.

(h) Explain one benefit of using solid state storage with a smartphone. (2)

One benefit of using solid state storage with a smartphone is that it has no moving parts that makes it more portable and produces less heat. Less heat means that components of a device last longer.

(i) Kiki's smartphone uses an open source operating system.
Which one of these describes the source code in an open source operating system? (1)
A It is owned by a company
B It is made available to users
C It is more secure
D It uses less processing power

B It is made available to users

(Total for Question 1 = 21  marks)
