Study Notes
Introduction to Computers
- Computers are ubiquitous and play a significant role in our daily lives, from family cars to home appliances and alarm clocks.
- We are living in the "Information Age" era.
Definition of a Computer
- A computer is an electronic machine designed for performing calculations and controlling operations expressed in logical or numerical terms.
- It is an electronic device that processes data, converting it into useful information for humans.
- A computer is a programmable, multi-use machine that accepts data and processes it into information.
How Computers Work
- Computers process data into information, which is summarized or manipulated for use in decision making.
Purpose of a Computer
- The primary purpose of a computer is to process data into information.
Difference between Hardware and Software
- Hardware consists of all the machinery and equipment in a computer system.
- Software, or programs, consists of all the electronic instructions that tell the computer how to perform a task.
Characteristics of Computers
- Speed: Computers process data at an extremely fast rate, with powerful computers performing billions of operations in just one second.
- Accuracy: Computers work with high accuracy, depending on instructions and design, with errors mostly occurring due to human errors.
- Diligence: Computers are free from monotony, tiredness, and lack of concentration, maintaining speed and accuracy throughout their calculations.
- Versatility: Computers can perform diverse tasks simultaneously, such as calculations, graphics, and searching.
- Storage Capability: Computers can store tremendous amounts of data and recall required data quickly, even if stored years before.
- Reliability: Computers are measured by their performance and do not require human intervention between processing operations.
Limitations of Computers
- A computer can only perform what it is programmed to do.
