# Data Processing Methods
|
|
|
|
How is data actually processed by computers?
|
|
|
|
## 1. Batch Processing
|
|
- Data is collected over time and processed **all at once** (in a batch).
|
|
- **Example**: Payroll systems (calculating salaries at the end of the month).
|
|
- **Pros**: Efficient for large volumes.
|
|
- **Cons**: Not immediate.
|
|
|
|
## 2. Real-time Processing
|
|
- Data is processed **immediately** as it comes in.
|
|
- **Example**: ATM withdrawals. You need to know your balance *right now*.
|
|
- **Pros**: Instant results.
|
|
- **Cons**: Complex and expensive.
|
|
|
|
## 3. Online Processing
|
|
- Similar to real-time, often used for internet applications.
|
|
- **Example**: Barcode scanning at a store checkout. The price is fetched instantly.
|
|
|
|
## 4. Distributed Processing
|
|
- Breaking a task into pieces and running them on **multiple computers** at the same time.
|
|
- **Example**: Google Search. Many servers work together to find your result.
