Answer:
Keep Source Formatting & Embed Workbook
Explanation:
Source formatting is used to apply the formatting from source document while copying and pasting.
Source is the place where the data is already placed and we want to move it make a copy of it on some other document. So if we don't want to change the formatting of source document, we choose source formatting from the options while pasting.
Embed is used to whenever we don't want to link the formatting with source document.
So,
You use the Paste Options button labeled <u><em>Keep Source Formatting & Embed Workbook</em></u><em> </em>if you want the pasted chart not to be linked to the source document and you want the pasted chart to keep the formatting from the source document.
Flip bit position 5 to accomplish this. This maps to hex value 0x20, where the least significant bit is assumed to be at position 0.
Example: ascii "A" = 0x41, "a" = 0x61. 0x41 xor 0x61 = 0x20.
You would implement a flip function by XOR'ing the character value with 0x20.
Answer:
Computer systems consist of three components as shown in below image: Central Processing Unit, Input devices and Output devices. Input devices provide data input to processor, which processes data and generates useful information that's displayed to the user through output devices. This is stored in computer's memory.
