CONTENT OF THE LESSON
LESSON 1 – INTRODUCTION
Computer receives, processes data to produce meaningful information.
Data is a raw fact and figure that needs to process to get their exact meaning.
The process is known as data processing.
MEANING OF DATA PROCESSING
Data processing is the process that convert data into information by the computers or any other electronic devices.
The process is automated that runs on computers and other information systems.
Data processing coverts raw data collected, filtered, sorted, processed, analyzed, stored, and then produced usable and desired form.

LESSON 2 – TYPES OF DATA PROCESSING
The types of data processing are as follows:
1. Batch Processing
2. Real – time Processing
3. Online Processing
4. Multiprocessing
5. Time-sharing
DEFINITION WITH APPROPRIATE EXAMPLES
1. BATCH PROCESSING
Batch data processing is the type of data processing that collect and process large volume of data all at once.
For examples,
- Payroll
- Line item invoices
- Supply chain
- Transactions of credit cards
- Generation of bills
- Processing of input and output in the operating system, etc.
2. REAL – TIME PROCESSING
Real – time data processing is the type of data processing that collect and process within seconds when the input is given.
For examples,
- ATMs
- Air traffic control
- Anti-lock braking systems in your car, etc.
3. ONLINE PROCESSING
Online data processing is the types of data processing that collect and process automatic as soon as data becomes available.
A good example of online processing is bar code scanning.
4. MULTIPROCESSING
Multiprocessing is the type of data processing that is capable of multitask at a time or simultaneously.
It executes and processes more than one data at the same time
A good example of multiprocessing is weather forecasting
5. TIME – SHARING
Time sharing data processing is the type of data processing that allocates resources and data in time to several computer users.
LESSON 3 REVISION AND WEEKLY ASSESSMENT (TEST)
As stated in performance objectives or lesson evaluation.
PRESENTATION
To deliver the lesson, the teacher adopts the following steps:
1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
2. Teacher organizes pupils in groups or pairs depending on the size of the class.
3. Teacher gives each of the group or pair mental sum.
4. Teacher also gives the same mental sum with simple device such calculator.
Pupil’s Activities – Perform mental sums with or without any simple device.
5. Teacher asks pupils to compare the result and differentiate between the sums.
Pupil’s Activities – Differentiate between manual and electronic data processing.
6. Teacher listen to the pupils and uses their responses to introduce the lesson.
Pupil’s Activities – Pay attention to the lesson introduction to understand the concept of data processing.
7. Teacher explains the meaning and types of data processing.
Pupil’s Activities – Explain the meaning and types of data processing.
8. Teacher summarizes the lesson on the board with appropriate lesson evaluation.
Pupil’s Activities – Participate actively in the summary of the lesson by responding correctly to the lesson evaluation and write as instructed.
CONCLUSION
To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
NEXT LESSON
LESSON EVALUATION
