A robotic arm is used to install the car windscreen. The robotic arm is controlled by a 6-bit signal. Each bit in the signal activates a component of the robotic arm when that bit is set to 1. What happens when you provide the number A?

• Move arm up and down

• Move arm up and in

• Move arm in and apply force to stabilize windscreen in place

• Move arm in and activate vacuum suckers to lift windscreen

A robotic arm is used to install the car windscreen. The robotic arm is controlled by a 6-bit signal. Each bit in the signal activates a component of the robotic arm when that bit is set to 1. What happens when you provide the binary number 110?

ASCII stands for...

• Australian Standard Code for Intercontinental Interchange

• Australian Standard Code for Intelligence Interchange

• American Standard Code for Information Interchange

• American Stable Code for International Interchange

Why was the ASCII code developed?

• To create more complex images and graphics on computers

• To standardize the representation of characters in computers and communication devices

• To replace binary code with a new numbering system

• To provide a system for encoding only numerical data

ASCII can be represented using 7-bit binary patterns. In other words, it contains...

• 64 characters

• 32 characters

• 128 characters

• 255 characters

UNICODE is better than ASCII because...

• it only supports English characters

• it can represent characters from many different languages and symbols

• it uses less computer memory

• it is much faster at processing data

Convert the following binary code to text by referring to the ASCII Table.

• beach

• harry

• malta

• hello
