1. COMPUTER FUNCTION AND CHARACTERISTICS REPORTERS: JAY R O. TAYO SHAREE ROSE C TABUGON CINRELLE MAE J. SULAPAS

2. W HAT IS COMPUTER? A computer is a programmable machine that can store, retrieve, and process data.It is an electronic device that can perform processes, calculations, and operations based on instructions provided by a software or hardware program.The term commonly refers to digital electronic computers. A computer can accept data (input), process it, and then produce outputs .

3. W HO IS THE FATHER OF COMPUTER Charles Babbage was considered the father of computing after his concept and invention of the Analytical Engine in 1837. The Analytical Engine contained an ALU (Arithmetic Logic Unit), basic flow control, and integrated memory, hailed as the first general-purpose computer concept.

4. Unfortunately, because of funding issues, this computer was not built while Charles Babbage was alive. However, in 1910, Henry Babbage, Charles Babbage's youngest son, completed a portion of the machine that could perform basic calculations. In 1991, the London Science Museum completed a working version of the Analytical Engine No. 2. This version incorporated Babbage's refinements, which he developed while creating the Analytical Engine

5. FUNCTIONS OF COMPUTER Data input: accomplished via input devices. Data processing: the core function of a computer. Information output: disseminating manipulated data for useful purposes. Data and information storage

6. BLOCK DIAGRAM COMPUTER

7. A n input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, computer mic, scanners, cameras, joysticks, and micropho nes. INPUT DEVICE

8. Processor Control Unit (CU): Controls all activities within the device. Arithmetic Logic Unit (ALU): Performs calculation and logic operations. Main memory (RAM): Stores data. CPU registers: Supply operands to the ALU and store results. Computer buses: Transmit data between components. CPU: CONTROL PROCESS UNIT

9. I nstruction execution: The CPU executes instructions provided by software programs. Data processing: The CPU carries out various calculations and manipulations on data. Memory management: The CPU manages the flow of data between different types of memory, such as the main memory (RAM) and cache memory. Communication control: The CPU controls all communication between RAM and all other input-output devices by interpreting data from and to other devices. FUNCTIONS OF CPU

10. Memory is any physical device capable of storing information temporarily, like RAM (random-access memory), or permanently, like ROM (read-only memory). Memory devices utilize integrated circuits and are used by operating systems, software, and hardware. MEMORY

11. TYPES OF MEMORY

12. WHAT IS PRIMARY MEMORY? Primary memory is the main memory of a computer that is directly accessible to a processor (CPU). It is also commonly known as internal memory and primary storage. The access time of the primary memory is faster than secondary memory .

13. WHAT IS SECONDARY MEMORY? Secondary memory is computer memory that is non-volatile and persistent in nature and is not directly accessed by a computer/processor. It allows a user to store data that may be instantly and easily retrieved, transported and used by applications and services.

14. ALU: ARITHMETIC UNIT ALU stands for Arithmetic Logic Unit. An ALU is a key component of the CPU which performs arithmetic and logical operations. It can perform billions of operations per second. An ALU circuit has the integration of four key components inputs, operands, outputs, and storage.

15. DATA PROCESSING I t includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output.

16. OUTPUT DEVICE Any information processed by and sent from a computer or electronic device. Data generated by a computer, including software-level results or physical documents. Peripheral devices that convert data into a form perceivable by users, such as monitors or printers. Output units that reproduce processed data for users. Devices that accept computer data and produce audio, video, or printed output.

17. CHARACTERISTICS OF COMPUTER

18. SPEED- The computer is characterized by its ability to process data at a high speed, reaching the point of processing millions of commands per second. ACCURACY - It is considered one of the most important characteristics of a computer, as it can perform orders and instruction that come to it with high degree of accuracy and effiency without any erorr.

19. DURABILITY: The computer is characterized by its high ability to work continously without fatigue or change in its accuracy level. STORAGE - The computer can store large amounts of data and information across several stoage devices for retrieval when needed.

20. VERSATILITY: The computer is used to perform different tasks almost simultaneously. STORAGE - The computer can store large amounts of data and information across several stoage devices for retrieval when needed.

21. COMPUTER SOFTWARE: A program which consist of a set of instruction that guides the computer hardware to operate effectively, there are two main types of software. SYSTEM SOFTWARE APPLICATION SOFTWARE

22. SYSTEM SOFTWARE: This controls the program inside your computer it includes the operating system and utility. APPLICATION SOFTWARE : The application software is simply called an app. It is a program that used to perform special task like writing letter , drawing or painting keeping record etc.
