Abstract• We write an article with PC

• Computer must memories it.

Human & Computer • Computer memorizes big amount of data.

• Human being forgets memory when the time passed.

Method of memory at the computer

• Computer isn’t learning while associating it

• Computer codes information uses a pattern.

Binary

• Code of the computer express in intelligible binary numbers.

• Computer saves code with a file at hard disk.

Experiment description

• How does file size change a file by many letters?

• How do you measure size??

Knowledge before experiment ①

• Letter : write a language.

• Text : data of this latter

• File : Structure that make it treating data

Knowledge before experiment ②

• Memory : Learning it without forgetting.

• KB : Unit to express amount of storage.

• 10 * 10 * 10

• MB : It is amount of storage as like as KB.

• 10 * 10 * 10 * 10 * 10 *10

Material of experiment ①

• Computer

• Microsoft word : Text editor

Material of experiment ②• Graph paper : write a figure & graph

• Understanding a tendency from

• experimental result.

• marker.

Method ①• 1:Give a 1000 words of ‘a’.

• 2:Copy & paste of it.

• 3:Make 1000 words files.

Method ②• 4:make name 1000.txt

• 5:In a similar manner, I perform it to 4000.txt.

• 6:Check a size of file.

Results

• A1000.txt : 1KB

• A2000.txt : 2KB

• A3000.txt : 3KB

• A4000.txt : 4KB

Consideration• Results increased by 1 KB

• 1000 words means 1KB

Other methods• Put a various letters together.

• Changing it into different font type or letter size

• Trying it at different application.
