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.

Digging into the Computer2 Philippine Copyright 2013 techFactorsInc

Have you ever wondered what’s inside your PC? What makes it such a powerful machine? Do you know that some of the parts that make it powerful are small in size? Knowing what’s inside a PC will help you understand how it works. It will give you an idea of how data is processed and stored.

What’s in the House?1The System Unit

The computer’s main hardware components are housed together as a system unit inside a casing. The casing protects the components from physical damage, heat, and moisture. Inside the casing

is a frame for mounting internal components. System units come in different shapes and sizes. The way internal components are arranged also varies. The form factor defines this physical arrangement.

The monitor, keyboard and system unit of a desktop computer are separate from each other. However, certain desktop computers, such as the Apple iMac, combine the monitor and the system unit in a single plastic case.

In portable computers, such as the laptop or netbook, the monitor and keyboard are combined with the system unit along with other computer components. Thus, portable computers take up less space than desktop computers.

Handheld devices like the tablet and smartphone also have the hardware and casing in one piece. These typically have a touchscreen that lets you type and navigate through your files and applications.

Inside the System Unit The following components comprise the system unit:

The motherboard is where the central processing unit, the chipset, memory slots, and expansion slots are attached.

• The power supply accepts and moderates electricity for the computer.

• The cooling fan makes sure that the temperature inside the system remains cool. If it is too hot, the system components will be damaged.

• The speaker produces beeps that warn of computer errors.

• The drive bays are where drives are placed. Internal drive bays are used for hard disks. External drive bays are used for drives which are accessed by users. Examples are, CD-ROM drives, DVD drives, and Blu-ray drives.

ROUND UP

The Motherboard

What Is a Motherboard?A motherboard is a board made of plastic or fiberglass and contains a set of

integrated circuits where an electric current flows through. The electric current that passes through the motherboard represents data. Data is transmitted within the computer system. The motherboard provides a link from the CPU to the input and output devices attached to the computer.

The motherboard contains memory slots where RAM chips are installed. It also contains expansion slots. Expansion cards are placed inside these slots to add more capabilities to the computer. For example, you can insert a video card or a network card into these slots.
