Study Notes
Introduction to Computer
- The term "computer" originates from Latin.
- Computers are electronic devices that manipulate data based on instructions.
- They can store, retrieve, and process data.
- Computers are used for numerous tasks, including document typing, email, internet browsing, accounting, database management, presentations, and games.
Functioning of a Computer
- Computers execute four primary functions:
- Input: Data and instructions entered into a computer. Sent to the Central Processing Unit (CPU).
- Processing: Actions taken on data to transform it into meaningful information. Includes calculations, comparisons, and decisions.
- Output: Making processed data available to the user, typically displaying the desired result based on input instructions.
- Storage: Permanent storage of data and programs. Used to retain information during program execution and allow retrieval.
Features of Computer
- Speed: Computers process data extremely rapidly, handling millions of instructions per second.
- Accuracy: Computers maintain a high level of accuracy, responding to user instructions precisely.
- Storage Capacity: Computers have large storage capabilities for data, determined by the size of the hard drive.
- Versatility: Computers can perform various tasks concurrently, carrying out multiple functions simultaneously.
- Automation: Once given instructions, computers execute tasks automatically without human intervention.
- Diligence: Computers exhibit tireless effort, consistently working without fatigue or errors.
Terms Related to Computer
- Hardware: The physical components comprising a computer system. This broad term encompasses all the tangible parts of a computer.
Introduction to Computer
- The word "computer" originates from the Latin language.
- A computer is an electronic device that processes information or data based on a set of instructions.
- It has the ability to store, retrieve and process data.
- Computers are used for various tasks such as typing documents, sending emails, browsing the internet, accounting, database management, presentations, and gaming.
Functioning of a Computer
- A computer performs four primary functions:
- Input: Data entered into a computer is called input. It sends this information to the Central Processing Unit (CPU).
- Processing: This involves the sequence of actions taken on data to transform it into meaningful information for the user. It includes calculations, comparisons, and decisions made by the computer.
- Output: This function makes processed data accessible to the user. It displays the desired result based on the input instructions.
- Storage: This function stores data and programs permanently. It retains information during program execution and allows for retrieval of any stored data.
Features of Computer
- Computers possess several key features:
- Speed: They can process data very quickly, at rates of millions of instructions per second.
- Accuracy: Computers provide high accuracy in their responses, following the input instructions precisely.
- Storage Capacity: Computers can store vast amounts of data, depending on the capacity of their hard disk.
- Versatility: They are capable of performing various tasks simultaneously, handling multiple functions at once.
- Automation: Once given instructions, the computer works autonomously, executing the task without requiring further human intervention.
- Diligence: Unlike humans, computers are free from fatigue and can operate continuously without experiencing errors due to tiredness or boredom.
Terms Related to Computer
- Hardware: This refers to the physical components that make up a computer system. It encompasses all the tangible parts of a computer.
