TLE ICT LESSON 2

Electronic Data Processing

The act of collecting data, turning it into information, and then using this information for decision-making into its useful form.

Data

Anything that you enter/input into a computer.

Input-Process-Output

What is the electronic data processing cycle

Input

it refers to all activities associated with recording data and making it available for processing

Processing

It includes different arithmetic and logical operations such as classifying, sorting, summarizing, comparing, and other manipulation techniques that convert data into information.

Output

It converts data into information that will be transmitted to the users of information. It is also the result of the process

Storage

It contains the processed data for future use and is a hardware component of a computer that permanently stores data.

Hardware, Software, Peopleware

What are the components of electronic data processing

Firmware

is a software that provides low-level control of computing device hardware

Hardware

It is the physical aspects of computers you can actually touch and contributes the computer system that performs the mechanics of operations

Monitor, power supply, cooling fan, mouse, audio speakers, motherboard, ram, etc

Examples of hardware

Software

Is the intangible part of the computer system that stores programs or data and it tells the computer what steps to take, what data to work on and what to do with the results.

Peopleware

It refers to anything that has to do with the role of people in the development or use of computer software and hardware systems.

Computer

is a programmable machine that can store, retrieve, and process data and performs a specific task or calculations depending on the set of instructions, or programs.

Super computer

very fast and most powerful computers and used in high-end scientific research centers, weather forecasting and other complicated tasks.

Mainframe

is a powerful multi-user computers that can support many hundreds or thousands of users simultaneously

Mini computer

mid-sized multi-user computer that are capable also for doing high-end processing but smaller compared to mainframe computers.

Personal computer

they are single-user computers which are portale and are easy to handle and use, they are also called microcomputers.

Microcomputer

is a small, rellatively inexpensive computer that is designed for individual use.

Personal digital assistant

What does PDA stand for?

Personal digital assistant (PDA)

it is designed to perform only specific task and can serve as your diary and a telephone.

Tablet computer

it is a wireless and flat screen computer which can be used for researching, playing games, watching movies, and listening to music.

Digital, Analog, Hybrid

Types of computers

Analog computers

computer that works by measuring rather than counting, like measuring graphs, voltage, pressure, speed and temperature.

Digital computers

these computers can handle more complex computations and process data at a higher speed. it can perform arithmetic operations like addition, subtraction, multiplication, division and also logical operations.

General purpose and Special purpose

2 types of purpose of digital computers

General purpose

are the computers commonly used today

Special purpose

are used for specific task or to solve a problem

Hybrid computers

combine the best features of analog and digital computers, it has the speed of analog and the accuracy of the digital. they are fast, reliable and provide accurate results.
