A transaction processing system is a system that divides work into individual transactions. Types of processing include batch processing, time sharing, real time processing, and transaction processing.
Data is processed to get the required results. Different operations may be performed on data. Therefore, data processing is defined as:"A sequence of operations on data to convert it into useful information is called data processing."The important operations that can be performed on data are:Arithmetic and logical operations on data to get required results.To send and receive data from one location to another.Classification of data.Arranging data into a specific order etc.The data processing is divided into three categories or levels.1. Manual Data Processing: In manual data processing, data is processed manually without using any machine or tool to get required result. In manual data processing, all the calculations and logical operations are manually performed on the data. Similarly, data is manually transferred from one place to another. This method of data processing is very slow and errors may occur in the output.In Pakistan, data is still processed manually in many small business firms as well as government offices & institutions.2. Mechanical Data Processing: In mechanical data processing, data is processed by using different tools like calculators or other mechanical devices. This method of data processing is faster and more accurate than manual data processing.3. Electronic Data Processing: It is the modern technique to process data. The data is processed through computer. Data and set of instructions are given to the computer as input and the computer automatically processes the data according to the given set of instructions.The computer is also known as electronic data processing machine. This method of processing data is very fast and accurate. Now-a-days, the data is processed and analyzed through computers. For example, the results of students are prepared through computer; in banks accounts of customers are processed through computers etc.
If you think of a CPU as the conductor of the computer then it is easy to understand
Any processing operation performed by hand.
Sound cards capture analog audio signals from microphones, music compact disks, musical instrument digital interface (MIDI; such as electronic-piano keyboards) devices, and other sound sources
Processing tasks in computers such as calculations are mostly performed in CPU's or any other part that is used and has processing, calculation capabilities. Most chips in a computer are for processing. Processing in a general way happends everywhere, from disk drive and port controllers on the ports to the CPU and controllers that control the RAM. These things also do some kinds of processing.
DISTRIBUTED PROCESSING: refers to LANDs designed so that a single program can run simultaneously at different sites.PARALLEL PROCESSING: is the simultaneous use of more than one CPU to execute a program. It allows programs to run faster because there are more engines (CPUs) running it.CENTRALISED PROCESSING: is performed in one computer or in a cluster of coupled computers in a single location. All data processing is performed in the central computer.
Handling deposits and withdrawals are two of the activities performed in a bank. Processing loans, and providing financial advice are two other activities performed in a bank.

Processing, input, output, linking, hypertexting
In batch processing the tasks are performed in batches. In time sharing, the operating system shares the time between each task.
