= 1 billion bytes or 1024 megabytes

megabyte

= 1 million bytes or 1024 kilobytes

terabyte

= 1 trillion bytes or 1024 gigabytes

kilobyte

= 1024 bytes

An electrical signal in a wire A measure of computer graphics and sound A physical signal that becomes a digital signal A single 1 or 0 in a digital signal

Match each ethical principle to it's definition:

Digital Property Rights: Recognizing an respecting the legal claims of others to online data, login information, creative works, and other digital assets. Confidentiality: Protecting data and information we're not authorized to share Human Dignity: respecting and honoring the inherent worth and right to privacy of other people Civility: observing rules of "netiquette" that promote courtesy and respect in online settings

IP Address

Every computing device that accesses the internet is assigned a unique Internet Protocol (IP) address. These addresses consist of either four (IPV4) or eight (IPv6) parts. An example of a four-part IP address is 137.75.68.206

HTML

Hypertext Markup Language is the programming language that web pages use to display content through web browsers, such as Internet Explorer or Google Chrome

Arrange the following from smallest to largest:

Kilobyte Megabyte Gigabyte Terabyte

What kind of file would be hurt most by a lossy compression algorithm?

Text document - audio and image files use lossy compression to take advantage of the limitations of human sight and hearing. However, text files and computer programs need to be stores with no data loss, or they will be corrupted. They are usually compressed using lossless algorithms, which compress the file without altering any of the data.

IoT

The internet of things refers to the network of physical devices that are connected to the Internet and capable of communicating and sharing data through sensors, network connectivity, barcodes, QR codes, and other technologies. The internet of things is made up of devices such as refrigerators, thermostats, street lights, and environmental tracking systems.

HTTP and FTP

The Hypertext Transfer Protocol (HTTP) is used to identify resources and transfer content on the web. Some web pages use the HTTPS protocol, which adds an additional layer of encryption to make data transfers more secure. The File Transfer Protocol (FTP) can also be used to transfer data between computers on a network.

Which type of digital picture can be scaled to any size without losing image quality?

Vector: vector images, such as fonts, can be scaled to any size without losing image quality

VoIP

Voice over IP sends voice phone calls using the TCP/IP protocol ver digital data lines. With VoIP, phone calls are made through a network connection rather than through a standard phone line. When you make a phone call, it is converted into digital data and sent through the network or one the internet

sampling rate

a measure of how many samples are made from an audio wave each second

bit

a single 1 or 0 in a binary digital signal

Wifi

a technology that provides wireless internet connectivity through wireless routers. A WiFi network uses radio waves to transmit data within a particular area referred to as a hotspot

frame rate

is the measure of how many individual images are shown each second in a video

bit depth

is how many bits are used to encode each individual sample in an audio recording

Intranet

is like a miniature internet. It's a private network, not a public one, but it uses many of the same technologies that are used on the internet, such as websites and email. An organization's intranet may or may not be connected to the public internet. A security boundary prevents devices on the internet from accessing the devices within the intranet.

color depth

measure of how many bits are used to encode each color in a picture or video

resolution

measure of how many pixels are in each individual image in a picture or video

URL

or Universal Resource Locator, is the reference or address to a resource on the internet. An example of a website URL is www.google.com/dog It consists of a protocol identifier (HTTP), a web server and domain name (www.google.com) and an optional path to the resource (/dog)

Civility

observing rules of "netiquette" that promote courtesy and respect in online settings

internet

often used synonymously with the Web, the term Internet typically refers to the vast collection of networking HARDWARE and physical computing devices that make up the Internet

byte

one byte is made of 8 bits. Each byte has 256 possible combinations, from 00000000 to 11111111

ISP

or Internet Service Providers, manage an access point to the internet. They don't manage the entire internet. If you think of the internet as a big freeway, then ISPs manage the on-ramp to the freeway. They're responsible for building the on-ramp and keeping it maintained and open, nut they are not responsible for the internet itself

Human Dignity

respecting and honoring the inherent worth and right to privacy of other people

DNS

short for Domain Name System, is a protocol the associates domain names (such as web servers) with unique IP addresses. DNS servers translate URLs into machine-readable IP addresses

The web

short for World Wide Web, the Web peers to the digital contend that is delivered over the internet, usually through a web browser

TCP/IP

stands for Transmission Control Protocol/Internet Protocol. It is the suite of protocols or rules that facilitate Internet communication.

raster images

stores the color value of each individual pixel (ex: digital photographs)
