Users can access their stored data from any device with an internet connection, making it convenient and accessible. It's commonly used for backup, file sharing, collaboration, and as a component of cloud computing services. Examples of cloud-based storages wherein we can store and retrieve data anytime GOOGLE FORMS Google Forms is a free online survey tool that allows you to create and distribute surveys, collect responses, and analyze data. It is part of Google's suite of productivity tools, which also includes Gmail, Google Docs, Google Sheets, and Google Slides.

A global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is also a network of networks. HOW DOES ONE CONNECT TO THE INTERNET? A person can connect with the internet with the use of an Internet service provider (ISP) by modem or Internet-ready cable digital subscriber line (DSL). A modem and a router serve distinct functions in a home network. A modem, short for "modulator-demodulator," is a device that connects the home network to the internet service provider. In contrast, a router is responsible for managing the traffic within the local network, directing data between devices and ensuring they can communicate with each other and access the internet. Coaxial cables are commonly used for cable television and broadband internet connections, using copper or aluminum conductors encased in insulating layers with metal shields. Fiber optic cables transmit data using pulses of light through thin glass or plastic strands, offering high-speed data transfer and minimal signal loss, making them ideal for fast internet and long-distance communication. Ethernet cables, often known as Cat5e, Cat6, or Cat7, use twisted pairs of copper wires for local area network connections, providing a reliable and familiar solution for wired internet and local network setups. NDDU-IBED-F-081 A switch is a device that connects various devices within a local network, allowing them to communicate with each other efficiently. It directs data traffic between devices like computers, printers, and more, helping them exchange information. An access point, on the other hand, is a device that enables wireless devices like smartphones and laptops to connect to a wired network, usually via Wi-Fi. It acts as a bridge, granting wireless access to the network, making it handy for expanding internet coverage in a home or office. A server is like a digital hub that hosts websites, stores files, and manages various tasks, ensuring that users can access and interact with data and services securely and efficiently. It operates around the clock, responding to requests from clients, such as web browsers or applications, to retrieve or deliver information, making it a cornerstone of modern information exchange and online experiences. HOW DOES THE INTERNET WORK? 1. The internet uses TCP (Transmission Control Protocol) to send and receive data. At the sending end: It takes a large chunk of data (such as a webpage, email message, etc) and breaks it into small packets (data). The IP is responsible for sending the packets out onto the Internet. Waves travel wirelessly using microwave signals and equipment such as a modem and a router convert these signals digitally-- converting them into binary signals (1's and 0's). NDDU-IBED-F-081 At the receiving end: It detects lost packets, and error packets because of network congestion, traffic load balancing, etc. Thus, requests the packet to be resent from the source. Rearranges and reassemble the packets back into the webpage, email message, etc. on the receiver’s machine. 2. It has an IP (Internet Protocol) IP is like a GPS it Picks a route for a packet, stopping at routers (device/s) which pick the next best machine/network to send the packet to (the router is the central switching device). If a communication line is down or broken, it sends the packet back to TCP and TCP sends it again to try a different route it Needs to be able to identify all the machines on the Internet, thus each machine has its own unique address. WHAT IS AN IP ADDRESS? Every computer that connects to the Internet has an identifying number (IP address) it consists of 3 numbers, and 4 octets with dots between them and each number ranges from 0-255. It changes whenever you connect to various networks. 192.168.1.87 - VALID IP ADDRESS 100.18.1.107 - VALID IP ADDRESS 172.20.65.19 - VALID IP ADDRESS 1.318.411.107 - INVALID IP ADDRESS WHAT IS A “URL”? As much as the HTTP (Hypertext Transfer Protocol) is concerned, the URL (Uniform Resource Locator) is also known as the website address, Every webpage is referred to by a URL. It is an address of a web document on a computer. Tim Berners-Lee in 1990 established the URL designation. Aside from “.com” which is used for commercial use, among them, you'll find.org, originally for nonprofit organizations, but now used more broadly, and.net, often associated with internet-related services and networks. The.gov extension is exclusively reserved for United States government agencies, while.edu designates educational institutions like universities and colleges. AUDIO AND VIDEO Video uses the power of Motion and Sound. It is a sequence of still images or frames that create the illusion of movement when played in succession. Each frame consists of a grid of pixels, and videos typically include both visual and audio components. A typical video has the filename.mp4 and some videos that are Apple-exclusive are on.MOV format. NDDU-IBED-F-081 FPS stands for "Frames Per Second." It is a measure of how many individual frames or images are displayed in one second in a video or animation. In the context of digital media, such as video games, movies, and computer graphics, FPS is crucial for determining the smoothness and quality of motion. A higher FPS, such as 60 or 120 FPS, results in smoother and more lifelike motion, making it particularly important in fast-paced video games and high- definition video content. Lower FPS, like 24 FPS in most movies, can create a more cinematic and traditional look, but it may appear less smooth during fast movements. Sounds/Audio are pressure waves of air. Visualize the sounds as a series of recurring waves called a waveform. Typical filenames of audio files are.mp3 for digitally produced sounds and.wma for audio recordings. Volume means that the higher the wave the louder the sound. Pitch or frequency the closer together the waves the higher the pitch. Sample Rate It is the # of samples taken in a second, Number of times/sec that the waveform is measured 1000 samples per second = 1 KHz (1000Hz). 8 KHz VOICE ONLY (telephone quality) 11.025 KHz AM Quality 22 KHz FM Quality 44.1 KHz CD Channels a. Mono signal - One channel (stream) of data reproduced equally on both speakers. b. Stereo signal - Consists of two channels (streams) of data, double the size of mono file, but higher quality.
