Operating System


OPERATING SYSYTEM 

OPERATING SYSTEM IS A COLLECTION OF SET OF SOFTWARE. WHICH MENAGE ALL THE RESOURCES OF THE COMPUTER SYSTEM.

IT IS AN INTERMEDIATER BETWEEN THE USER AND COMPUTER.

CHARACTERISTICS

1. SHEDULING

2. MEMORY MENAGMENT

3. SECURITY

4. DEVICE MENAGMENT

5. FILE MENAGMENT.

ADDVANTADES OF OS

1. OS PROVIDE A INTERFACE FOR THE USER IN THE FORM OF MENU ICON,BUTTON.

2. OS ALSO ALLOW US TO SHARING RESOURCES WITH OTHER USER .

3. IT HELPS USER TO UNDERSTAND THE FUNCTION OF A COMPUTER.

4. IT IS VERY EASY TU USE.

DISADDVANTAGES OF OS

1. IF THE OS IS CRUUPTED THAN ITS WILL AFFECT INTIRE SYSTEM. THE COMPUTER SYSTEM WILL NOT WORK.

2. ONLY SOME TASK RUN AT A TIME.

TYPES OF OPEREATTING SYSTEM

1. BATCH OPERATING SYSTEM.

2. TIME SHARING OPERATING SYSTEM.

3. DISTRIBUTION OPERATING SYSTEM.

4. NETWORK OPERATING SYSTEM.

5. REAL TIME OPERATING SYSTEM.

6. SERVER OPERATING SYSTEM.

7. CLIENT OPERATING SYSTEM.

____________


 1. BATCH OPERATING SYSTEM

THE BATCH OPERATING SYSTEM WILL WORK TO SUBMIT SIMILLAR KINDS OF JOB TOGETHER.IN THIS OS USER DO NOT INTRACT DIRECTLY WITH OUR COMPUTER SYSTEM.

ADDVANTAGES

IT IS USEFULL WHEN WE WORKING WITH LARGE FILE,WHICH CAN TAKE MORE TIME EXACUTE.

DISADDVANTAGES

WHEN THE JOB IS SUBMITTED, THE USER DID NOT HAVE ANY INTRACTION WITH IT.
__________

2. TIME SHARING OPERATING SYSTEM

TIME SHARING OPERATING SYSTEM WORKS WHICH TIME SHARING CONCEPT. THE CPU WILL PROVIDE A SAME TIME PERIOD TO ECAH AN EVERY PROCESS .

TO COMPLET ITS TASK AS SOON AS POSSIBLE. WEATHER IT A LONG PROCESS OR SHORT PROCESS.

ADDVANTAGES

IF THE PROCESS OF A TASK IS COMPLETED,THEN TIME IS INCREASE  B/W OTHER TASK.

DISADDVANTAGES 

SOMETIME IN THIS OPERATING SYSTEM THER MAY BE A PROBLEM DATA COMMUNICATION.
___________

3. DISTRIBUTION OPERATING SYSTEM.

WHEN MANY COMPUTER ARE THE INTERCONNECTED TO EACH OTHER THE INTERNET  FOR THE PURPOSE OF SHARING THAIR TASK. 

ADDVANTAGES

IF THE NODES IS OVER USED THEN THE DISTRIBUTED OPERATING SYSTEM SHARE THAT LOAD TO OTHER NODES OF THE NETWORK.

DISADDVANTAGES

IF THE NETWORK IS BROKEN COMMUNICATION IS A BROKEN.
___________

4. NETWORK OPERATING SYSTEM.

NETWORK OPERATING HAVE A SERVER THAT CONNECT MANY COMPUTER , SO WE CAN  EASILY SHARE OUR FILE TO EACH OTHER AND MANY MORE FROM THE SERVER.

 MCHINE TO ALL THE COMPUETR WHICH ARE CONNECTED THROUG A NETWORK.

ADVANTAGES

NETWORK OS PROVIDSE A SECURITY WE CAN NEED TO UPGRADE ONLY SERVER MACHINE.

DISADVANTAGES

IF SERVER MACHINE ARE BROKEN THEN THE ENTEIRE NETWORK IS A BROKEN.

___________

5. REAL TIME OPERATING SYSTEM

REAL TIME OPERATING IS A VERY USEFUL OS. WHERE WE CAN REQURED A QUICK RESPONSRE  FOR EXAMPLE MISSILE SYSTEM . 

IN THIS CPU PROVIDE A MAXIMUM EFFORTS IN THIS TASK.

ADVANTAGES

REAL TIME OS PROVIDE A QUICK RESPONSE HENCE GENRALLY USED IN SCIENTIFIC ENGINEERING NASA AND MANY MORE ORGANIZATION.

DISADVANTAGES

THIS OPERATING SYSTEM IS VERY COSTLY.

_____________

6. SERVER OPERATING SYSTEM

1. IT CAN BE USED TO PROVIDE SERVICES TO MORE THAN ONE CLIENT.

2. IT IS A COMPLEX OPERATING SYSTEM.

3. IT RUNS ON A SERVER IT IS AN OPERATING SYSTEM DESIGNED TO BE USED ON A SERVER.

4. THIS PROVIDES MORE SECURITY.

5. IT HAS MORE PROCESSING POWER.

6. IT IS HIGHLY EFFECTIVE.

FOR EXAMPLE: LINUX, REDHEART.

____________

7. CLIENT OPERTATING SYSTEM

1. IT CAN RECEIVE SERVICES FROM A SERVER.

2. IT SERVES ONE USER AT A TIME.

3. IT IS A SIMPLE OPERATING SYSTEM.

4. IT RUNS ON CLIENT DEVICES LIKE LAPTOP COMPUTERS ETC.....

4. OS IS THE OPERATING SYSTEM THAT RUNS INSIDE THE DESKTOP.

5. THIS LEASE PROVIDES SECURITY.

6. IT HAS LOW PROCESSING POWER.

7. THIS IS A LESS EFFICIENT.

FOR EXAMPLE: WINDOW

TCP/IP MODEL

  HISTORY OF TCP/IP MODEL THE TCP/IP MODEL WAS DEVELOPED BY VINT CERF AND BOB KAHN IN THE 1970S. THEY WERE BOTH WORKING AT THE DEFENSE ADVANCED RESEARCH PROJECTS AGENCY (DARPA) AT THE TIME. Vint Cerf And Bob Kahn CERF AND KAHN WERE TASKED WITH DEVELOPING A NEW NETWORK PROTOCOL THAT WOULD BE MORE RELIABLE AND EFFICIENT THAN THE EXISTING PROTOCOLS. THEY CAME UP WITH THE IDEA OF USING A LAYERED APPROACH, WHICH WOULD ALLOW EACH LAYER TO FOCUS ON A SPECIFIC TASK. THIS LED TO THE DEVELOPMENT OF THE TCP/IP MODEL, WHICH IS STILL THE BASIS FOR HOW DATA IS TRANSMITTED OVER THE INTERNET TODAY. CERF AND KAHN ARE OFTEN REFERRED TO AS THE "FATHERS OF THE INTERNET" FOR THEIR WORK ON THE TCP/IP MODEL. THEY WERE INDUCTED INTO THE NATIONAL INVENTORS HALL OF FAME IN 2004 FOR THEIR CONTRIBUTIONS TO THE DEVELOPMENT OF THE INTERNET. HERE ARE SOME OTHER NOTABLE PEOPLE WHO CONTRIBUTED TO THE DEVELOPMENT OF THE TCP/IP MODEL: JON POSTEL: POSTEL WAS THE FIRST CHAIRMAN OF THE INTERNET ENGINEERI...

Internet Protocol (IP) Address

  IP ADDRESS IT IS A UNIQUE ADDRESS THAT WE CAN ASSIGN TO DEVICE .SO THAT DEVICECAN COMMUNICATE WITH EACH OTHER. WE CANNAOT ASSIGN SAME IP ADDRESS IN ANY TWO DEVICES IN OUR NETWORK. IF WE WILL DO THIS THEN IT WILL BE  CAUSE A CONFLICT ERROR. TWO VERSION OF IP ADDRESS: 1: IPV4 ; 2: IPV6 ; IPV4 32 BITS AND IPV6 128 BITS. AN IP ADDRESS, OR INTERNET PROTOCOL ADDRESS, IS A SERIES OF NUMBERS THAT IDENTIFIES ANY DEVICE ON A NETWORK.  COMPUTERS USE IP ADDRESSES TO COMMUNICATE WITH EACH OTHER BOTH OVER THE INTERNET AS WELL AS ON OTHER NETWORKS. TO FIND THE IP ADDRESS CLASS WE NEED TO LOOK AT THE FIRST DIGIT OF THE IP ADDRESS. AND BY LOOKING AT THE FIRST DIGIT, WE CAN GUESS THE SUBNET MASK TO WHICH CLASS IT BELONGS. CLASS A IP ADDRESS SUBNET MASK 255.0.0.0 CLASS B IP ADDRESS SUBNET MASK  255.255.0.0  CLASS C IP ADDRESS SUBNET MASK 255.255.255.0 IANA TABLE IP RANGES                 IANA   ( Internet Assigned Numbers Au...
