 IP ADDRESS STANDS FOR INTERNET PROTOCOL ADDRESS: It is a unique number provided to each and every device. It is in the form of intergic number and seperated by dot . EXAMPLE: 192.168.10.26 ADDRESSING: IP (logical) MAC(physical) IP address divides in two parts: IPV4: Length 32 bits Octet 4 Rnage 0 to 255 4 billion IP address IPV6: Length 128 bits Octet 8 length FFFF(65535) 340 trillion IP address NOTE: There are many number of people in the world. In the IPV4(version) there are less possibility to use the IP adress individually. So to fulfill the need and requirements of each person individually there is a need of a letest version that is in the form of IPV6.And now each person has an unique IP address. USES OF IP: Private IP ( for any personal use there is need of IP address) Public IP ( for use of public like as a website) CLASSES OF IP: Class A Class B Class C Class D  Class E NOTE: There are five classes of IP adress and 1st three are provided for  common use . and 4t...

 GENERATIONS: There are five generations of computer which are following: 1ST GENERATION: ECKERT and MAUCHLY developed the first electronic computer in ENIAC in 1946 in USA. Vacume tube is the core element of 1st generation. The time period of 1st generation of computer was from 1946 to 1959. Consumes lot of electricity. It is not portable.     2ND GENERATION: The second generation of computer are IBM 700 ATLAC and ICL 1901 Transistor was the core element of 2nd generation The time period of 2nd generation was from 1959 to 1965 Required less power to operate. Smaller reliable and faster than 1st generation of computer. 3RD GENERATION:  The 3rd generation of computer are IBM 360 NCR 395 TDC developed by JACK KILBY. Integrated circuits( Ics) was the core element of the 3rd generation. The time period of 3rd generation  computer was from 1965 to 1971. Development of minicomputer. In this generation O.S was developed. 4TH GENERATION: The fourth generation of compute...

OPERATING SYSYTEM: NOTE: On the request of an viewer in the previous article i will explian the operating system in detail. I will try my best hope you all understand it. First of all as you know that operating system is an interaction between the hardware and users. If we want to know that what is software? we can say that  Set of tested programms and documention and we can also say that set of instructions that tells the computer what to do. There are two types of software:     1-System software Basicaly it is a paltfrom that is used to run the overall application software. OR we can say that it operates the application software like LINKER  LOADER DEBUGGER    2. Application software Designed for any specific task like WINDOWS MEDIA PLAYER VLC MS OFFICE Our mission is to know how an operating system is more important for interaction between a hardware and user? I will give an example to clear your concept. EXAMPLE: If you want to ON/OFF  an FAN . Ss ...
