- Convert the value 25 into an 8-bit binary number. Show your working.
- Explain why the telephone number 07700 901012 should be stored as a text field type and not a numeric field type.
- Name the bus used to transfer instructions from the main memory to the processor.
- Companies must adhere to health and safety legislation for employees using computer systems regularly.
Adjustable workstation chairs allow computer users to change the height and seating position to prevent back ache.
Name one other workstation feature and describe how it reduces a risk to health. - Describe the purpose of JavaScript scripting language.
Apparently this is some british standardized test thing.
-
Convert the value 25 into an 8-bit binary number. Show your working.
This is a poorly defined question:
- It doesn't say what base "25" is. Also, "25" isn't a value, but a set of glyphs that can be interpreted to have a value.
- It doesn't say that the 8-bit binary number needs to have the same value as "25". More generally: there is no indication of what conversion mechanism is required.
Edit: added more pedantry! (And I missed locallunatic's observation....)

They want you to attach a video of you doing the conversion?
-
Name the bus used to transfer instructions from the main memory to the processor.
Bertie the Bus, except my systems use a F40PH to transfer data. You can't beat the data transfer capacity of those on over-land routes.

Explain why the telephone number 07700 901012 should be stored as a text field type and not a numeric field type.
a) As long as you can dial the number from a keypad, it doesn't matter which way it is saved.
b)Storing as number will take less bytes than storing as string, as all strings are eventually stored as numbers.
c)Storing as text will help in formatting the number so that all levels of Europe, Asia, America, Africa and Antartica can display the format. Actually storing as number also allows us to do this since any number can be converted to a string.
d) Text fields are overrated in computing. I once stored my entire autobiography in a number field. The right combination of numbers can help you achieve anything in life. Ask numerology experts and they will agree.
If you want exam board standard answer, look here.

The whole of the computer's memory is just one big number field.

Describe the purpose of JavaScript scripting language.
The main purposes of javascript scripting languages are as follows:
Processing power can be shared with the client. Clients are now getting powerful.
Roundtrips to server can be saved. All validation implemented at javascript will save valuable network speed.
It make HTML designers believe that they are good programmers. This is a positive reinforcement message that at sublime levels can then make them alter their resumes and apply for programming jobs.
It makes experienced C & C++ developers feel inadequate since they don't understand any of it. This gives bragging point to web developers.

I'm sorry, but this isn't The Bad Ideas thread.

Thanks for explaining the joke to everyone else.

TRWTF is calling it Computer (or Computing) "Science".

I have a packet of biscuits on my desk (Arnott's Creamy Chocolate [the biscuits, not the desk]) which reduces my risk of dying of starvation.
