Group B: True or False (5 × 1 = 5)
1. Write true or false: 5×1=5
i)High-level languages require no translators to convert code into machine language.
ii)An interpreter converts the entire high-level program into machine code at once.
iii)Supercomputers are the most powerful computers in terms of processing speed and storage capacity.
iv)The <head> tag contains the main content of the webpage.
v)The “forever” block runs the script only once.
i) False (High-level languages require translators to convert code into machine language.)
ii) False (An interpreter converts code line by line, not the entire program at once.)
iii) True
iv) False (<head> tag contains metadata, not the main content.)
v) False (The “forever” block runs the script continuously until stopped.)
