1. Check it out ¼ Sheet of Pad Paper 1-4 Classification of Computers 5-7 Elements of computer system 8-11 Components of computer hardware and its example (give 1 in each component)

2. Computers are classified into four (4) different types based on its processing power and size: Classification of Computers Supercomputer Minicomputer Microcomputer Mainframe Computer

3. The Elements of Computer System A computer system is a collection of entities that are designed to receive, process, manage, and present information in a meaningful format. It has 3 elements that will make a computer really useful. Elements of a Computer System Hardware Software Peopleware

4. 1. Hardware refers to the physical, tangible computer equipment and devices which provides support for major functions such as input, process, output and storage. Components of Computer Hardware Input Device Output Device Process Device Storage Device

5. A. INPUT DEVICES are composed of a device that accepts data and instructions from the user or from another computer system Keyboard Microphone Scanner Mouse

6. B. OUTPUT DEVICE is any piece of computer hardware that displays results after the computer has processed the input data that has been entered. Monitor Printer Speaker Projector

7. C. PROCESS DEVICE is the computer’s circuitry in the system unit. It plays an important role in processing operations. It is used to process data, using instructions from the program. C.1. Motherboard / Mainboard / System Board – is the main circuit board of a computer. It contains all the circuits and components that run the computer.

8. C.2. CPU (Central Processing Unit) - The processor is the main “brain” or “heart” of a computer system. It performs all of the instructions and calculations that are needed and manages the flow of information through a computer.

9. C.3. RAM – (Random Access Memory) RAM is volatile, meaning it holds data only when the power is on. When the power is off, RAM's contents are lost.

10. C.4. Video Card/GPU (Graphics Processing Unit) - also called a display card, graphics card, display adapter, or graphics adapter is an expansion card which generates a feed of output images to a display device (such as a computer monitor).

11. D. STORAGE DEVICE. stores data and programs. These hold data, information, and programs permanently

12. 2. Software – this term refers to the collection of electronic instructions that tells the computer what to do. It is a computer program that is installed in your computer.

13. Kinds of Computer Software A. System Software coordinates the activities and functions of hardware and software. It controls the operations of computer hardware and provides an environment or platform for all the other types of software to work in. It is the most basic type of software in any computer system, which is essential for other programs, applications and the whole computer system to function A. System Software

14. A.1. Operating System – is the program that, after being initially loaded into computer by a boot program, manages all the other programs in a computer. Examples– Microsoft Windows, Mac OS, Linux, Ubuntu

15. A.2. Utility Programs – are small, powerful programs with a limited capability, they are usually operated by the user to maintain a smooth running of the computer system.

16. B. Application Software is a computer program that performs a specific task. (Application software examples – MS Office, OpenOffice, Media Players, MS Access, educational software, media development software, Antivirus software, etc.)

17. 3. Peopleware – the most important element of a computer system is its users. The following types of people interact with a computer system: a. System Analysts - are people who design the operation and processing of the system b. System Programmers – are people who write codes and programs to implement the working of the system. c. System Operators – are people who operate the system and use it for different purposes. Also called the end users like students, teachers, and other professionals.

18. “Filling to know” System Software coordinates the activities and functions of hardware and software. It controls the operations of computer hardware and provides an environment or platform for all the other types of software to work in. It is the most basic type of software in any computer system, which is essential for other programs, applications and the whole computer system to function 2 1 3 Application Software is a computer program that performs a specific task. 4 People ware is the most important element of a computer system is its users. 5
