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

CSST COURSE 1.0

Q1. WHAT IS A ADDRESSING. Network addressing is like a two-part delivery system:   Logical Addressing (IP): This is like your permanent address (e.g., 192.168.1.1) that lets data find your device anywhere on the internet. Physical Addressing (MAC): Think of this as a unique ID for your device's network card (AA:BB:CC:DD:EE:FF) used for local delivery within your network. Q2. WHAT IS A PACKET AND FRAME . Packets: Layer: Network Layer (Layer 3) Content: The actual data you want to send, like an email, a video, or website information. Addressing: Contains logical addresses (IP addresses) to identify the sender and receiver on the network. Size: Can vary depending on the data type, but generally larger than frames. Travels across networks: Packets can travel across different networks, like the internet, as they are routed based on IP addresses. Frames: Layer: Data Link Layer (Layer 2) Content: The packet wrapped with additional information for local deliver...

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...
