1. Living in the IT era

2. Living in the Information Technology Era was written specifically for K-12 graduates who are transitioning from senior high school to higher education. It is one of the 3-unit elective courses offered for general education under the Mathematics, Science, and Technology domain. Using the same title of the course as described by the Commission on Higher Education, this subject explores the science, culture, and ethics of information technology, its various uses and applications, as well as its influence on culture and society.

3. Introduction to Information and Communications Technology Information and Communications Technology (ICT) is an extensional term for Information Technology (IT) that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals), and computers, that enable users to access, store, transmit, and manipulate information. ICT is technology that supports activities involving information. Such activities include gathering, processing, storing and presenting data. Increasingly these activities also involve collaboration and communication. Hence IT has become ICT: information and communication technology.

4. The Pros of Living A Digital Life The benefits of technology are all around us and can be seen in everything from electricity to global communications. Our cars and cell phones have navigation systems to ensure that we do not get lost. We can pay our bills at the touch of a button on the internet. Our cellphones have evolved into tiny little computers in our pockets. We can now communicate with anyone, anywhere in the world at any time not only by telephone, but also by video conference, instant messenger and email. With faster internet connections being introduced on a daily basis it seems like the only limit to what technology can do is our own imagination. All of these innovations have one goal in mind – to make our lives easier!

5. Let’s look at a couple of examples. First, consider that you are the parent of a teenager. It’s 10pm and your 14-year-old daughter has missed her curfew by 30 minutes. What goes through your mind? Did she get kidnapped? Hit by a car? Attacked? The possibilities are terrifying. However, thanks to technology she has her mobile phone and you can give her a call (because your teenager will not think to call you first!)  and establish that she is perfectly fine, but missed the bus home from the movies and had to wait for the next one. Some parents might then think, ‘wait, she could be lying! What if she is with that no good boy from a close by town?’ Thankfully, technology has your back and you can use the GPS tracker on the mobile phone monitoring app you installed on her phone and confirm that yes, she truly is at the bus stop by the movie theatre! You could even check her text messages to confirm that she really did go to the movie with Jill and not Jack! Another scenario could be that you just left the office and are half way home when a colleague calls you in a panic because they need an urgent file from you. You would need to get off the subway and head back to the office, right? WRONG! Thanks to technology you can use your mobile device to log onto your cloud storage and email the file to the colleague and still make it home for dinner!

6. The Cons of Life in The Technology Era It all sounds great, but there are still plenty of downsides. It seems like every other day the news is reporting cyber-crimes as criminals begin to take advantage of our technology dependence. People have their credit card numbers stolen and businesses have their information hacked or computer systems disabled. We are so dependent on technology that if for example, the bank’s computer network failed, it is likely that most day-to-day operations would grind to a halt! While global communications are a great innovation they are also a dangerous one as the internet affords everyone some degree of anonymity. Let’s go back to the example where you are parenting a teenage girl. What if that cinema date was actually her meeting up with someone she got talking to online? Someone she thought was 14 years old like her, but in reality was a 50-year-old predator? Even although most parents try to teach kids about internet safety, teens believe that they are invincible and know best. ‘It will never happen to me’ is a phrase uttered by every teen at some point!

7. Thankfully, although technology created this dangerous situation, technology can also resolve it. If you have mobile phone spying software installed on her phone then you could have intercepted those plans to meet and put an end to it before anything bad had a chance to develop. So is technology good or bad? The answer, quite simply is both! Technology is a great thing that makes our lives so much easier, but at the same time it must be treated with respect as it also has negative sides. It’s kind of like a hammer. You can use the hammer to build things or to harm others. In theory, technology is neutral. At the end of the day it’s up to us to use it for good or evil.

8. What is Computer? It is an electronic device which consist of several components that together provide a capability of executing a stored program.

9. Parts of the Computer

10. Mouse - A  computer mouse , often simply referred to as a  mouse , is a hand-held pointing device that detects two-dimensional motion relative to a surface. Keyboard - A  computer keyboard  is a typewriter-style device which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Monitor - A  computer monitor  is an output device that displays information in pictorial form. A monitor usually comprises the display device, circuitry, casing, and power supply.  CPU - A  central processing unit  ( CPU ), also called a  central processor  or  main processor , is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions.

11. What is Computer Hardware and Software? Computer hardware  includes the physical, tangible parts or components of a computer, such as the mouse, CPU, monitor and keyboard. Computer software , or simply  software , is a collection of data or computer instructions that tell the computer how to work. This is in contrast to physical hardware, from which the system is built and actually performs the work. 

12. What is Input device? input device  is a piece of computer hardware 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, mouse, scanners, digital cameras, joysticks, and microphones.

13. What is Output device? An  output device  is any piece of computer hardware equipment which converts information into human-readable form. It can be text, graphics, audio, and video. Examples of output device. - Computer monitor - Printer - PC speaker - Projector

14. Classes of computers Microcomputer Mainframe computers Supercomputer

15. Microcomputer A  microcomputer  is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board(PCB). These computers include: Desktop computers  – A case put under or on a desk. The display may be optional, depending on use. The case size may vary, depending on the required expansion slots. Very small computers of this kind may be integrated into the monitor. In-car computers ( carputers )  – Built into automobiles, for entertainment, navigation, etc. Game consoles  – Fixed computers built specifically for entertainment purposes. Laptops and notebook computers – Portable and all in one case. Tablet computer  – Like laptops, but with a touch-screen, entirely replacing the physical keyboard. Smartphones,  smartbooks , PDAs and palmtop computers  – Small handheld computers with limited hardware.(Internal storage)

16. Mainframe computers The term mainframe computer was created to distinguish the traditional, large, institutional computer intended to service multiple users from the smaller, single user machines. These computers are capable of handling and processing very large amounts of data quickly. Mainframe computers are used in large institutions such as government, banks and large corporations. 

17. Super computer A Supercomputer is focused on performing tasks involving intense numerical calculations such as weather forecasting, fluid dynamics, nuclear simulations, theoretical astrophysics, and complex scientific computations. A supercomputer is a computer that is at the front-line of current processing capacity, particularly speed of calculation. The term supercomputer itself is rather fluid, and the speed of today's supercomputers tends to become typical of tomorrow's ordinary computer. Supercomputers are the most powerful, are very expensive
