Study Notes
What is a Computer?
- A computer is an electronic device that receives data (input), processes data, stores data, and produces a result (output).
- Basic components include the system unit, keyboard, monitor, and mouse.
Computer System
- A computer system consists of multiple electronic components categorized into four parts: input, processing, storage, and output.
- Input: Provides data to the computer (keyboard, mouse, touchscreen)
- Processing: Moves and processes data inside the computer (CPU, memory, sound card)
- Storage: Stores software and data (hard drive, USB Flash drive, optical device)
- Output: Provides results to the user (monitor, projector, printer)
Characteristics of Computers
- High Speed: Computers can perform millions or billions of calculations in a fraction of a second.
- Storage: Computers use different types of memory storage to keep data and information, ranging from large capacity to fast retrieval.
- Accuracy: Computers are 100% accurate in calculations; errors usually come from data input or software issues.
- Reliability: Computers are reliable machines, with hardware and software components designed for consistent performance and easy maintenance.
- Versatility: Computers can perform multiple tasks simultaneously with ease.
- Diligence: Computers do not experience tiredness or lack of concentration. They can work continuously without errors.
- Resource Sharing: Computers can connect to other devices and share resources, such as printers and hard drives.
Benefits and Usage of Computers
- Business: Used for payroll, sales, budget planning, financial management, and information systems.
- Banking: Dependent on computers for online transactions, tracking records, and automated services like ATMs and CDMs.
- Government: Used for passport and visa systems, driving licensing, traffic systems, and national ID systems.
- Military: Used in defense and many military weapons have computerized control systems.
- Healthcare: Used for keeping patient health records, medicine history, and controlling equipment in laboratories.
- Education: Vital tools for E-learning, student information systems, and teacher and student evaluation systems.
- Communication: Enables easy communication through email, chatting, and video conferencing.
