Data is converted to binary to be stored by a computer. Tick (✓) one box to show the correct statement about why data is converted to binary for storing in a computer. A Binary uses numbers and characters to store all the data. B Binary is one type of data that a computer can store. C Data is processed by logic gates that can only be set as binary numbers. D Only binary numbers can be input into a computer.
A smartphone has a quad-core 2.4 GHz processor.
The processor performs the fetch-decode-execute (FDE) cycle. The first register used in the FDE cycle stores the location in random access memory (RAM) of the next instruction. Identify the name of this register.
Describe the actions that take place in the decode stage of the FDE cycle.
Give the name of one component that is used in the execute stage of the FDE cycle.
Explain the advantages of the smartphone having a quad-core processor instead of a dual-core processor.
The smartphone has built-in input and output devices. Identify two input devices that could be built into the smartphone. 1 2
Identify two output devices that could be built into the smartphone. 1 2

An optical mouse is connected to a computer using a universal serial bus (USB) cable.
State the purpose of the optical mouse.
The USB cable transmits data using the serial half-duplex data transmission method. Describe how the serial half-duplex data transmission method transmits the data.
One benefit of using the USB cable to connect the optical mouse to the computer is that bits of data are less likely to arrive out of order. Give two other benefits of using the USB cable to connect the optical mouse to the computer. 1 2
One function performed by the operating system is managing peripherals. A role of this function is to install the drivers needed for the optical mouse. Complete the table with the missing functions and roles of an operating system.
| function | role |
|---|---|
| providing an interface | |
| It makes sure that two processes do not access the same memory location at the same time. | |
| managing interrupts | |
| It allows the user to set a username and password. |
An integrated development environment (IDE) has two types of translator: a compiler and an interpreter.
Give the purpose of the compiler and the interpreter.
Identify one other type of translator.
The table contains statements about compilers and interpreters.
| letter | statement |
|---|---|
| A | An interpreter translates and executes the code one variable at a time. |
| B | A compiler displays an error report when it is unable to run the code due to syntax errors. |
| C | An interpreter stops translating as soon as it finds an error in the code. |
| D | A compiler translates the whole code at once and then it is executed. |
| E | A compiler produces a non-executable file. |
Two of the statements in the table are not correct. Give the letter of each incorrect statement. Suggest a corrected statement for each. letter of the incorrect statement 1 corrected statement letter of the incorrect statement 2 corrected statement
A translator is one function of an IDE. Identify two other functions of an IDE. State the purpose of each function. function 1 purpose function 2 purpose
Web pages need to be located and retrieved to be displayed on a device.
Complete the paragraph about locating and retrieving web pages. Use the terms from the list. Some of the terms in the list will not be used. You should only use a term once. certificate database domain name server (DNS) encryption hypertext markup language (HTML) internet protocol (IP) address low-level language protocol request uniform resource locator (URL) web browser web server The user types the URL into the address bar. The web browser sends the domain name from the URL to the .......................................................................................... . This searches for the matching ............................................................................... and sends this back to the ............................................................................... . The web browser sends a ............................................................................ to the web server for the web page. The web server then sends the data for the web page back to the web browser. The web browser renders the .................................................................................. to display the web page.
The transmission of data between the web browser on a device and a web server can be secured using the secure socket layer (SSL) protocol. Complete and annotate the diagram to show the process of sending the data using SSL. web browser web server
A child has a robot animal. The robot animal can perform actions like making a noise and walking around a room. If the robot animal hears a clapping sound, it makes a noise. If the robot animal is walking and it senses an object is less than 10cm away, it will stop.
Give one suitable sensor that the robot animal could use to identify a clapping sound.
Give two suitable sensors that the robot animal could use to identify if an object is nearby. 1 2
One characteristic of the robot animal that makes it a robot is that it has electrical components that include sensors, a microprocessor and actuators. Give one other characteristic of the robot animal that makes it a robot.
The sensor continuously sends digitised data to the microprocessor. Describe how the microprocessor uses the data from the sensor to stop the robot animal when an object is less than 10cm away.
The robot animal uses artificial intelligence (AI). Explain how the robot animal can use AI to learn where objects are in a room.
A student opens a document on their computer and inputs text.
Explain how the computer represents the text.
