IT Service management
ITIL - framework of know-how, best approaches, best practices, etc. designed to create a successful business utilizing IT services.
ITIL is “de facto standard” of IT service management.

Basic theory
numeral system base 2 (Binary) 0,1 base 8 (Octal) 0,1,2,3,4,5,6,7 base 10 (Decimal) 0,1,2,3,4,5,6,7,8,9 base 16 (Hexadecimal)
0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
Convert numerical base
Base 10 → Base 2 346 = 256+64+16+8
Binary = 101011010
512 256 128 64 32 16 8 4 2 1
1 1 1 1 1
Convert numerical base
Base 2 → Base 8 Binary = 101011010 Split 3 digit = 101 011 010 Octal = 532
Base 2 → Base 16 Binary = 101011010 Split 4 digit = 1 0101 1010 Hexadecimal = 15A

Computer Units
A “bit” is the smallest unit of data which can be handled by a computer (written as 'bit' or 'b')
Units 8bit = 1Byte 1024Byte = 1KiloByte(KB) 1024KB = 1MegaByte(MB) 1024MB = 1GigaByte(GB) 1024GB = 1TeraByte (TB) 1024TB = 1PetaByte(PB)

Language processor
JIT Compiler Compile source to p-code (portable code) like as
java call “byte code” Interprete by p-code by VM on each platform like as
JVM or .net runtime
Markup Language
Markup Language used to write logical structures in text by means of tags. A “logical structure” affects textual and graphical layout, character appearance (written format), and other elements. Through the use of tags, they embed control characters into text to express information related to details such as layout, character embellishment, and hyperlinks. Two typical examples of markup languages are “HTML” and “XML.”

Internet Protocol (IP)
“IP” is a protocol that corresponds to the network layer (Layer 3) in the OSI model. Common functions of IP are “addressing” and “routing.”
IP Address
IP Address
Public IP is IP assign by internic (THNIC in thailand) use to connect to internet
Private IP is IP reserve for use for local. Such as LAN in company.
Subnet is a prefix to separate Network and Host number for IP
Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.0
IP Range
Public IP Class A 1.0.0.0 - 127.255.255.255 Class B 128.0.0.0 - 191.255.255.255 Class C 192.0.0.0 – 223.255.255.255
Private IP Class A 10.0.0.0 - 10.255.255.255 Class B 172.16.0.0 - 172.31.255.255 Class C 192.168.0.0 - 192.168.255.255
Domain Name System
A “domain name” uses a combination of characters to represent an IP address
DNS is a method to mapping between domain name and ip address to connected on internet
