Study Notes

Introduction to Data Processing

Data comprises unorganized facts such as text, numbers, images, and sounds; initially, it lacks meaning and structure.
Processed data is known as information, derived through various operations on raw data.

Key Terms in Data Processing

Bit: The smallest unit of data, represented as 0 or 1, used for character representation.
Byte: A group of bits.
Field/Column: A collection of bytes.
Record/Row: A set of fields.
File: A group of related records.
Database: A collection of related files.

Data Processing Overview

Involves the collection and manipulation of data to generate meaningful information.
Central to data processing is the Central Processing Unit (CPU), divided into:
- Control Unit (CU): Manages and coordinates operations, similar to a brain directing a body.
- Arithmetic and Logic Unit (ALU): Performs calculations and comparisons necessary for data processing.

Data Storage Methods

Direct Access Storage: Allows selection of data from any location using specific addresses.
- Floppy Disks: Flexible magnetic storage, affordable and easily transportable, capacity varies.
- Magnetic Disks: Thin, circular plates used for direct-access secondary storage; widely utilized for applications and data.

Program and Data Security

Security measures protect against unauthorized access to systems and data.
Common techniques include:
- Passwords: Control access levels for users.
- Access Control Packages: Restrict access to critical files and monitor unauthorized software.
- Removable Storage Media: Ensures sensitive data is kept offline for security.

Additional Concepts

Uninterruptible Power Supplies (UPS): Protects data within computer systems from unexpected power failures.
Comparison of Computer Types:
- Personal computers usually cost less than midrange and mainframe computers but may be increasing in usage.
The relation between real-time and batch processing systems allows firms to utilize both depending on their needs.
