Computing homework- 16th June
Cards in this deck (9)
- 1What is a character set?Every character is stored as a binary number, and all of the characters the computer can recognise is the character set
- 2Name the three main character setsASCII, Extended ASCII, Unicode
- 3How many bits are used for ASCII7 bits are used in ASCII
- 4How many bits are used for Extended ASCII8 bits are used in Extended ASCII also known as 1 byte
- 5How many bits are used for Unicode16 bits are used in Unicode also known as 2 bytes
- 6Give one disadvantage and one advantage of using ASCIIAdvantage: Doesn't take much storage space compared to Extended ASCII
Disadvantage: Cannot represent as much characters as Unicode - 7Give one advantage and one disadvantage of using Extended ASCIIAdvantage: Doesn't take much storage space compared to Unicode
Disadvantage: Cannot represent as many characters as Unicode can - 8Give one advantage and one disadvantage of using UnicodeAdvantage: Can represent 65536 characters
Disadvantage: Takes more storage space than ASCII and Extended ASCII - 9Describe how characters are represented in a computer systemEach character within the character set is set its own unique binary code, and so the computer is sent a binary code when a key is pressed on a keyboard and recognises the character.
