ForewordAs an essential productivity tool, the computer is something that

everyone should be familiar with. But as they say, it’s hard to teach old dogs new tricks, so it’s better to learn computers beginning at a young age. TechFactors (TFI) recognizes the need to do this, especially when it comes to integrating information and communication technology (ICT) into the curriculum of the Department of Education (DepEd).

The DigiTITANS elementary education courseware program of TFI provides computer education from Grade 1 to Grade 6, giving students a learning experience that they can be proud of later in life. It equips them with the essential competencies, both in Microsoft-based and open source applications, that will make them more effective students in high school. They gain practical know-how on productivity tools and discover pertinent facts and concepts that give them a better grasp of ICT in general. It’s the DigiTITANS way of preparing and empowering Filipino grade school students for success in a wholly ICT-dominated future.

The convenience of having a DigiTITANS book, teacher’s guide, and a ready access to interactive activities using server-network and online resources provide a handy way for students to actively learn computer skills even through the simple task of going through the accessing process. It’s this hands-on dynamic manner of learning that makes DigiTITANS a valuable teaching tool adaptable to the needs of the teachers and gets the nod of parents.

Versatility, together with the plain and simple delivery of lessons that comprise a stair-step system based on current software use, access, and trends, makes the DigiTITANS courseware an ideal system for schools looking to supplement their DepEd curriculum with a structured ICT-based learning system.

Learning Goals


Computers and Society2 Philippine Copyright 2013 techFactorsInc

Our world today is very different from what it was fifty years ago. Many of the changes we now have are because of computers. How did computers come about? Do you know what things around you make use of computers?

What Computers Do for UsMany of the things we have today make use of

computers. Alarm clocks are put together using computers. Some school buses have some computer-controlled parts. A laptop is a small computer that can be carried around.

Computers process data and change it into useful information. Information is what we need to know to help us understand concepts or do certain actions. With the help of computers, we can easily understand data and get information we need.

Computers use a type of language to process data. But unlike English, Filipino, or Chinese, the computer has only two “words”: 1 and 0, making up the binary system. Codes of 1s and 0s are called bits. Data is stored using these bits, which the computer translates into a language we can understand. That’s why you don’t see a string of 1s and 0s on your computer screen. Instead, you see words that you understand.

Hardware and SoftwareComputers are made up of hardware and software. We can compare

hardware to a television set, while software are like the shows we watch on TV. Just like a television is useless without shows, hardware needs software to be useful.

Lesson


The All-Around Everyday Machine4 Philippine Copyright 2013 techFactorsInc

There are three main kinds of hardware:

Software make the computer run. Application software, for example, help your computer perform certain tasks.

Factors That Define ComputersComputers can be classified according to their purpose, the way in which

they read data, and their size and power.

General purpose computers have many uses. Most computers are for general purposes. A computer for a specific purpose has only one special use. Microwave ovens and washing machines have specific purpose computers inside them.

An analog computer reads data using electricity or rotating gears, like what you find in a watch. A digital computer, such as a calculator, reads data in the form of bits. A computer that is both analog and digital is called a hybrid computer.

Input devices allow you to put data into the computer. The mouse and the keyboard are input devices.

The central processing unit (CPU) is the “brain” of the computer. It processes information inside the computer using software. It also uses software to control both input and output devices.

Output devices allow you to get information from the computer in different forms. The computer monitor is an example of an output device.

The personal computer comes in many sizes. We use it to write, edit, draw, and play games. The desktop is bulky and is designed to sit on your desk. The laptop is small enough to sit on your lap and to carry anywhere. The netbook and handheld PCs are even smaller. The smartphone and tablet, for example, are just the size of your palm or hand. The workstation is as big as a desktop, but it is connected to another computer called a server, where other computers are connected.

Kinds of ComputersThe medium-sized minicomputer is a multiuser computer.

It lets as many as ten to a hundred people work on a workstation at the same time.

The mainframe is also a multiuser computer. But it is bigger and more powerful than the minicomputer. It lets hundreds or thousands of people work at the same time over a single system. It is used by some big companies.

The supercomputer is the fastest among all computers. It is used for big computing jobs such as weather forecasting, engineering design and testing, and military operations.

Computers are part of our everyday lives. There are so many things we can do with the computer. It is a useful machine that makes working easier and playing much more fun.
