When I added 1+1=10, I moved 1 to the next row and that gave me 1 in the third row.

16GB X 1024MB = 16,384MB
16,384MB X 1024KB = 16,777,216KB
16,777,216KB X 1024 bytes = 17,179,869,184 bytes
17,179,869,184 bytes / 4 bytes = 4,294,967,296 bytes or words

What is the ASCII hexadecimal code for a blank space? It is 0000. Why is it necessary to represent a blank as a separate character in text? It defines ASCII symbol table and it is a data value

EXERCISE 1.4.4
Use the web to explore the origin of the Universal Character set (UCS)-ISO/IEC 10646- and explain why it was developed. Compare a contrast this system with ASCII. What is the relationship of ASCII to the UCS encoding?
UCS was developed for representation transmission, interchange, processing, storage, input and presentation of the written form of the languages of the world as well as additional symbols. ASCII and Unicode are two character encodings, basically they are standards on how to represent difference characters in binary so that they can be written, stores, transmitted, and read in digital media. The main difference between the two is the way they encode the character and the number of bits that they use for each. ASCII originally used seven bits to encode each character. This was later increaser to eight with Extended ASCII to address the apparent inadequacy of the original. In contrast, UCS uses a variable bit encoding program where you can choose between 32, 16 and 8-bit encodings. Using more bits lets you use a limited choice but you save a lot or space. UCS was designed in such a way that the first eight bits marched that it than most popular ASCII. So if you open an ASCII encoded file with UCS, you still get the correct characters encoded in the file in order to contain compatibility with one another.
EXERCISE 1.4.5
Use the web to explore the application of UTF-8 text encoding. What features are provided by UTF-8 that are not provided by ASCII? Why it was chosen to replace ASCII as the standard for the web?
UTF-8 can represent every character un Unicode character set. It was designed for backward compatibility with ASCII. The first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single octet with the same binary value as ASCII, making valid ASCII text valid UTF-8-encoded Unicode as well.

When I open the file myname.txt, my name appears in the top, and the file is saved in the disk C:, the physical storage has reduced 1KB that was the space that the folder myname.txt used.

Some of the issues that disk fragmentation has on your system is that it makes it harder to your CPU to find the files it needs making down the overall performance on the system.
