To convert a CSV file to a TSV file, you can use the following strategies:
1.Text Editor:
– Open the CSV file.
– Replace all commas with tabs.
– Save the file with a `.tsv` extension.
2.Spreadsheet Software:
– Open the CSV file in software like Microsoft Excel or Google Sheets.
– Use the “Save As” or “Download As” option to select TSV format.
3.Command-Line Tools:
– Use tools like `awk` or `sed` to replace commas with tabs.
“`bash
awk ‘BEGIN {FS=”,”; OFS=”\t”} { $1=$1; print }’ file.csv > file.tsv
“`
4.Programming Languages:
– Write a script in Python, R, or another language to read the CSV and write it as TSV.
“`python
import pandas as pd
df = pd.read_csv(‘file.csv’)
df.to_csv(‘file.tsv’, sep=’\t’, index=False)
“`
Choose the method based on your tools and preferences.

A process is like a task that a computer is executing. It may be in different states depending on what it is doing. The following are the main process states:
New :Process has just been created.
Ready: Process is ready to run but waiting for CPU to get free.
Running: Process is being executed by CPU now.
Waiting: Process waits for some event (for example, waiting for user input or for a file to be read).
Terminated: This means that the process has completed execution and has died.From New to Ready: Here, we have set our process up and it’s ready to execute.
From Ready to Running: While running, the CPU chooses this process of all other processes that are available at that time
From Running to Waiting: In order for the processor or any of its resources not to go idle when running the program, it should pause until an event occurs such as an input clause
From Waiting to Ready: The state which follows after waiting can only happen if some events occur otherwise it will remain constant.
From Running to Terminated: The task has been accomplished by this process

- New:
- Description: The process is being created. In this state, the operating system is setting up the process control block (PCB), memory allocation, and other necessary resources.
- Example: When you start a new application, it begins in the new state while the OS sets up its environment.
- Ready:
- Description: The process is prepared to run but is waiting for CPU allocation. It has all the resources it needs except the CPU.
- Example: Multiple processes might be in the ready state, waiting their turn to be executed by the CPU.
- Running:
- Description: The process is currently being executed by the CPU. At this moment, the CPU is actively working on the instructions of this process.
- Example: When the CPU starts executing the instructions of a text editor, the text editor process is in the running state.
- Waiting (or Blocked):
- Description: The process cannot continue executing until some external event occurs (such as an I/O operation completion). It is not ready to use the CPU until this event is resolved.
- Example: If a process needs to read data from a disk, it will move to the waiting state until the disk I/O operation is completed.
- Terminated (or Exit):
- Description: The process has finished its execution. This state means that the process has completed its task and is being removed from the process table.
- Example:When you close an application, the process goes into the terminated state after finishing its execution and cleanup activitie

Process States Explanation: In operating systems, a process is a program in execution. As a process runs, it goes through different states.

Process States Explanation:
In operating systems, a process is a program in execution. As a process runs, it goes through different states. These states represent the current condition of the process in the system. Let’s break down the main process states:
1. New: The process is being created.
2. Ready: The process is waiting to be assigned to a processor.
3. Running: The process is currently executing on the processor.
4. Waiting (or Blocked): The process is waiting for some event to occur (like I/O completion).
5. Terminated: The process has finished execution.
Examples:
1. New: When you double-click on an application icon, the operating system creates a new process.
2. Ready: Multiple programs open on your computer, waiting for their turn to use the CPU.
3. Running: The video game you’re currently playing.
4. Waiting: When you click “Save” in a document and wait for it to complete.
5. Terminated: When you close an application, and it finishes its execution.
Now, let’s visualize these states with a diagram:
Explanation of the diagram:
1. A new process starts in the “New” state.
2. It then moves to the “Ready” state, waiting for the CPU.
3. When the scheduler selects it, it goes to the “Running” state.
4. From “Running,” it can:
a) Go back to “Ready” if its time slice expires.
b) Move to “Waiting” if it needs to wait for a resource or event.
c) Proceed to “Terminated” if it completes execution.
5. From “Waiting,” it returns to “Ready” when the waited-for event occurs.
This cycle continues until the process terminates.

Different types of CPU scheduling
CPU scheduling is a crucial aspect of operating systems, and there are several types of CPU scheduling algorithms. Here are some of the most common ones:
1. First-Come-First-Served (FCFS):
In FCFS scheduling, the process that arrives first in the ready queue is executed first. This algorithm is simple and easy to implement, but it can lead to poor performance and starvation of other processes.
2. Shortest Job First (SJF):
In SJF scheduling, the process with the shortest burst time is executed first. This algorithm is optimal in terms of average waiting time, but it requires knowledge of the burst time of each process, which is not always possible.
3. Priority Scheduling:
In priority scheduling, each process is assigned a priority, and the process with the highest priority is executed first. This algorithm is useful in systems where certain processes require more urgent attention than others.
4. Round Robin (RR) Scheduling:
In RR scheduling, each process is given a fixed time slice (called a time quantum) to execute before the next process is scheduled. This algorithm is fair and provides good response time, but it can lead to overhead due to context switching.
5. Preemptive Scheduling:
In preemptive scheduling, the operating system can interrupt a running process and schedule another process. This algorithm is used in most modern operating systems and provides better responsiveness and fairness
6. Non-Preemptive Scheduling:
In non-preemptive scheduling, once a process is scheduled, it runs until it completes or blocks. This algorithm is simpler to implement but can lead to poor performance and starvation of other processes.
