Parts of a computer Everything inside the computer is connected to a circuit board called the

'motherboard'. The motherboard has sockets for low-level programming (BIOS), the computer's brain, called a CPU; the computer's memory (RAM,ROM and CMOS)

CPU: stands for 'Central Processing Unit' and is the 'brain' of the computer. Most CPU's today are made by Intel and bear such names as 'Pentium', 'Pentium Pro' and 'Pentium II'.

RAM: RAM is what you know as “Memory”, as in how much memory does your computer have? It is not permanent memory - the RAM is erased when the computer turns off. Permanent memory is stored on the hard drive.

The hard drive uses disks that are made of aluminum or glass (and therefore 'hard'). Each disk can store much more information than either a floppy or CD-ROM.

Generally when we talk about a floppy disk drive we are talking about the drive that uses the 3.5 inch 1.44Mb floppy disk in it. There have been other types that have  come and gone.

CD-ROM stands for Compact Disk – Read Only Memory. The original name was WORM drive, which meant Write Once Read Many.

At one time there was the PC keyboard, the AT keyboard, and the 101 key enhanced keyboard, which had F9 through F12 keys and a separate numeric keypad. Now the 101 key enhanced keyboard is the standard type and keyboards are named according to the type of connection it makes to the computer. 

A modem allows your computer to connect to another computer using the normal telephone line. It converts data from a computer format, which requires many wires, into a format that can be sent using only the two wires of a telephone line.

The USB (Universal Serial Bus) connector is the newest type port (connector) on the PC. It is extremely easy to use. You just plug in a USB compatible device and the computer automatically configures itself to use the device.

A computer peripheral, or peripheral device, is an external object that provides input and output for the computer. Some common input devices include: keyboard mouse touch screen pen tablet joystick

MIDI keyboard scanner digital camera video camera microphone

Some common output devices include: monitor projector TV screen printer plotter speakers

KINDS AND FUNCTION OF KEYBOARD

ERGONOMIC KEYBOARD The artifact of this keyboard is slightly broader and different in shape, when compared       with the normal keyboard. In this key board certain space will be existing between the two sets of keys and the countered shape of this key board allow the users to place their hands in the natural position to type.

XT An obsolete type, these keyboards only support the older computers such as IBM 8086/8088, XT-286. Not supported by present computers, keyboards are much larger than the modern keyboards and the “Enter” key is backward-”L” shaped.

MINI PS/2 The MINI PS/2 keyboards are very small in size and are compatible with the PS/2 computers. This keyboard resembles the laptop keyboard and it is square in shape. This keyboard is composed of fewer key and do not have detach numeric keypad.

MULTIMEDIA The multimedia keyboard is specially designed for the people who are much into multimedia designing. This keyboard is just like the standard key board, but composed of additional keys for the multimedia purposes such as multimedia application launch, volume control and mute button.

INTERNET The Internet keyboards are designed for wider range of multimedia applications, these keyboards are specially designed for the intense Internet user. The special keys included in this keyboard are the home key, back and forward key, e-mail launch key, and browser launch key etc.

WIRELESS A wireless keyboard, the name itself doles the meaning that this keyboard can be operated without addressing a wired connection to the processor. The wireless

keyboards are also referred as Cordless keyboards; these keyboards require batteries to provide the electricity which usually delivered through a PS/2 or USB cable.

GAMING As the name suggest, gaming keyboards are those who are into gaming and need easy access to the keys that are usually utilized in gaming.

MEMBRANE Membrane keyboards are one of the keyboard types, which are used very rarely. The keys integrated in this keyboard are non-moving pressure-sensitive keys.

PARTS OF KEYBOARDS

Function Keys

Across the top of a keyboard are a row of keys called the Function Keys. Each key is composed of the letter F and a number, ranging from F1 to F12. Each of these keys performs a specific operation based on the software you are using.

Numeric Keypad

Larger keyboards include an extra section to the right that contains the numeric keypad. This consists of the numbers 1 through 9, an asterisk, a slash, a dash, a plus sign, an "Enter" key and a period. The keypad also includes the “Num Lock” key, which activates the keypad.

Navigation Keys

The navigation keys, also called the direction keys, navigate through documents and websites. Examples of navigation keys are the up, down, left and right arrows.

Typewriter Keyboard

The center of the keyboard contains the largest number of keys and includes the space bar, letters and numbers. Most of your typing involves these keys.

Special Keys

Other keys include the "Alt" and "Ctrl" keys, which enable specific functions; the "Tab" key, which inserts the cursor and the "Shift" key, which enables capital letters or symbols located on the number keys.

Escape

The "Escape" key, often displayed as "Esc," lies in the upper left-hand corner of the keyboard. It is used to cancel operations.

HOME KEY POSITION

Look at your keyboard under the "f" and the "j" keys. There should be a small bump at the bottom of each key. Your left index finger goes on the "f" and your right index finger goes on the "j." Allow your other fingers on your left hand to rest on the remaining keys beside the "f" (FDSA). Then allow your remaining fingers on the right hand to rest on the keys beside the "j" (JKL;). This is called the "home row" and it is your anchor in keyboarding.

Natural resources that the Philippines has

The Ocean

Being surrounded by the ocean, it is no surprise that the Philippines relies on the waters as an important natural resource. There are more than 640,000 square miles of territorial waters in the Philippines and within these waters, there is an abundance of marine life and materials that are valuable to the nation's people and those across the world. At least 65 species of the 2,400 available species in Filipino waters have solid commercial value, and the crabs, seaweed, pearls and other ocean treasures make the sea among the top resources for this archipelago.

Minerals

The Philippines is not a petroleum-rich country, but the land is still full of many valuable minerals. There are an estimated 21.5 billion metric tons of metal deposits in the Philippines and 19.3 billion metric tons of nonmetal minerals in the ground. Nickel is the most abundant deposit in the Philippines, while iron and copper are also present in significant amounts.

Major Crops

The volcanic history of the archipelago combined with the wide plains available throughout the nation make the Philippines a prime spot for growing crops for domestic use and export. The Central Luzon, Cagayan Valley and Negros are among the many places with fertile soil in the Philippines. This land is the nation's primary source of livelihood. The chief crops of the nation include rice, corn, sugarcane, abaca and tobacco, according to the Philippine History website. The rice and corn are used domestically, but the rest is used as a major export. The Philippines also exports a number of pineapples and bananas.

Flora

The tropical climate in the Philippines makes it an ideal location for flowers and plants. The islands have more than 2 million species of plants, and several of them are found nowhere else on the planet. Much of the flora in the Philippines, while diminished by over harvesting, is used as an important natural resource as ingredients in commercially exported products.

Filipino traitsFamily OrientationFilipinos possess a genuine and deep love for family which includes not simply spouse and children, parents and siblings, but also grandparents, aunts, uncles, cousins, godparents and other ceremonial relatives. To the Filipino, one's family is the source of personal identity, the source of emotional and material support and one's main commitment and responsibility.Concern for family is manifested in the honor and respect given to parents and elders, in the care given to children, the generosity towards kin in need, and the great sacrifices one endures for the welfare of the family. This sense of family results in a feeling of belongingness and rootedness and in a basic sense of security. 

Pakikipagkapwa-taoThe Filipino on knocking at the door of another says, "Tao po". "It is a human being." he presents himself to another as a fellow human being. His ideal is to behave like a human being to another. "Magpakatao." One of the worst reproaches you can make against a Filipino is, "HIndi marunong makipagkapwa-tao." He does not know how to deal with others as a human being. He practices pakikipagkapwa-tao through the famous Filipino hospitality, his generosiity and helpfulness in times of need (pakikiramay), his deep sense of gratitude (utang na loob), and his spirit of cooperation (bayanihan). A prime value of Filipinos is smooth interpersonal relationships. Because of his pakikipagkapwa-tao, the Filipino is usually easy to get along with. We are very friendly people. 

flexibility, adaptavility and creativityFilipinos have a great capacity to adjust and to circumstances and the surrounding environment, both physical and social. Unplanned or unanticipated events are never overly disturbing or disorienting as the flexible Filipino adjusts to whatever happens. We possess a tolerance for ambiguity that enable us to remain unfazed by uncertainty or lack of information. We are creative, resourceful, quick learners and have the ability to improvise and make use of whatever is on hand in order to create and produce. 

Hard Work and IndustryGiven the proper conditions and incentives, Filipinos work hard indeed. This is perhaps best illustrated by our overseas workers who do both menial and superior jobs competitively in other countries. Even here, despite the often meager compensation. Filipinos show themselves remarkably industrious. 

Faith and ReligiosityThere is no Filipino atheist. The Filipino psychology is essentially religious. We pray often. We are attached to the church. When we have problems, we turn to God. 

Ability to SurviveDespite grinding poverty, many Filipinos survive. They can even make a livelihood from garbage dumps. We have survived many invaders, oppressors and natural calamities, and have come out with hope and determination to carve out our existence anew. Significantly, the typical Filipino greeting is "Mabuhay! Live!"

All of these values are eminently evangelical. The Filipino has what "Tertullian calls" a naturally Christian soul.
