1. Unsigned Integers

RAM (RANDOM ACCESS MEMORY)
-for fast storage and retrieveable data that will stored temporary.
-faster saving data
-consist of capacitor and transistor
-more efficient
-similar assembly of some electronic components
-capacitor can be in two states which charges and discharges
-transistor act as a switch
-contains billion of assembly
-each of assembly hold a bit of data
-when an assembly assembly is charged will represent 1 and when its discharged will represent 0

HDD (HARD DISK DRIVE)
-permanent storage data
-such as documents, music, video and pictures
-save data permanently in form of file
-contains hundreds of billions of division of which can be magnetised and demagnetised
-if the division is not magnetised then it willnot hold ny data and vice versa if the division is magnetised
-for example, if magnetised point up show 1 and if pointing down will show 0
-operating system sees all the data as calastrophe of 8 bit (00000000)

4 bit=Nibble
8 bit=Bytes

1 KILOBYTE=1024 bytes
1 MEGA BYTE=1024 kilo bytes
1 KB=1024 bytes
1 MB=1024 KB
1 GB=1024 MB
1TB=1024 GB

1 KB=1024 Bytes
1 Kb=1024 bits

Short=2 bytes=16 bits
Int=2 shorts= 4 bytes=32 bits
Long=2 int=4 shorts=8 bytes=64 bits

2. Signed Integers Part 1

-the number in abide tell us a positive number or a negative number
-show two compliment to be one compliment on each other
-this bit is going to hold the sign of the number with it's a positive number or a negative number
- If the bit 0 it’s a positive number and if the bit 1 it’s a negative number
-The integer is calculated by the magnitude bit. Calculation is using binary to decimal conversion.

3. Signed Integers Part 2

-A binary sequence can even undergo a “two's complement” where it is the complement of a “one's complement”, which results in the original value of the binary sequence.
-flipped the bits of one's complement and then add 1 to it, it will form two's complement.
-smallest integer that can be represent is -128 while the largest integer is 127.
-know that a complement can combine with another complement of the binary number become two complement.

4. Floating Point Numbers

-a precise and large numbers
-wider range of very small numbers
-know how to represent real numbers in scientific form
-have to fix the point and convert it to float to make it more understand in computer
-the way of representing real numbers is called Fixed point representation because the binary point is conceptually fixed.
-NAN is not a real number while denormalized represent all component value in binary is zero.

5.Fixed Point Numbers

-a real number is not a complex number
-know that a real number is any integer or a rational or an irrational number
-value digit depends on the position of the digit.
-to know that the exponent use decimal point float over the number.
-know how to write the binary number in binary scientific form.
-all number are equal gap in number line.
-use sign-magnitude to represent sign and magnitude of the number.
