Internet Protocol Stack DNS, TCP, IP, and Physical Internet
Domain Name Domain names are used to identify one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com. Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains. For example: gov - Government agencies edu - Educational institutions org - Organizations (nonprofit) mil - Military com - commercial business net - Network organizations ca - Canada th - Thailand

To simplify things pulling out specific differences to make one solution work for multiple problems
File Sizes Bytes, KB, MB, GB ,TB A byte is a sequence of 8 bits (enough to represent one alphanumeric character) processed as a single unit of information. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits).
File Sizes (2) Put another way, a bit is either an ‘on’ or an ‘off’ which is processed by a computer processor, we represent ‘on’ as ‘1’ and ‘off’ as ‘0’. 8 bits are known as a byte, and it is bytes which are used to pass our information in its basic form - characters.
File Sizes (3) A byte is a sequence of 8 bits (enough to represent one alphanumeric character) processed as a single unit of information. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits). byte- A series of 8 binary bits that digitally represent a single character to the computer. Example: 00000001 = 1 Learn more here. kilobyte- Approximately 1,000 bytes. Learn more here. megabyte- Approximately 1,000,000 bytes. Learn more here. gigabyte - Approximately 1,000,000,000 bytes. Learn more here.
Internet Protocol Layers DNS: Translates a URL into an IP address. Note that a DNS request still is conducted over TCP/IP TCP: Breaks larger messages into multiple packets and ensures all packets are received and ordered correctly IP: Assigns IP addresses to computers and routes packets of data to the correct address The Physical Internet: copper telephone wire, fiber optic cable, radio waves, etc
Server A computer that awaits and responds to requests for data. Example: a DNS server awaits and responds to requests for urls to be translated to IP addresses.
Client A computer that requests data stored on a server. Example: When you type an address into your browser, your computer is the client and it sends the requests to the DNS server.

Malware Software that is intended to damage or disable computers, computer systems, and other software programs
For Loop A typical looping construct designed to make it easy to repeat a section of code using a counter variable. The loop combines the creation of a variable, a boolean looping condition, and an update to the variable in one statement.
Modulo A mathematical operation that returns the remainder after integer division. Example: 7 MOD 4 = 3
Documentation A description of the behavior of a command, function, library, API, etc.
Canvas A UI, user interface, element to use in HTML/JavaScript which acts as a digital canvas, allowing the programmer to draw on web pages, and manipulate pixels to draw basic shapes, figures and images. In computer science and visualization, a canvas is a container that holds various drawing elements (lines, shapes, text, frames containing other elements, etc.). It takes its name from the canvas used in visual arts.
Moore’s Law A prediction made by Gordon Moore in 1965 that computing power will double every 1.2-2 years, it has remained more or less true ever since.
List 9
Encryption A process of encoding messages to keep them secret, so only authorized” parties can read it.
Cracking Encryption When you attempt to decode a secret message without knowing all the specifics of the cipher, you are trying to “crack” the encryption.
Public Key Encryption Used prevalently on the web, it allows for secure messages to be sent between parties without having to agree on, or share, a secret key. It uses an asymmetric encryption scheme in which the encryption key is made public, but the decryption key is kept private.
Asymmetric Encryption Used in public key encryption, it is scheme in which the key to encrypt data is different from the key to decrypt.
Loop The action of doing something over and over again.
Cipher An algorithm that performs encryption or decryption. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. ... When using a cipher the original information is known as plaintext, and the encrypted form as ciphertext.
Cipher text Ciphertext is encrypted text. Plaintext is what you have before encryption, and ciphertext is the encrypted result. The term cipher is sometimes used as a synonym for ciphertext, but it more properly means the method of encryption rather than the result.
Caesar Cipher A technique for encryption that shifts the alphabet by some number of characters
Random Substitution Cipher An encryption technique that maps each letter of the alphabet to a randomly chosen other letters of the alphabet.

Event Listener (a loop) A command that can be set up to trigger a function when particular type of event occurs on a particular UI element. An event listener is a procedure or function in a computer program that waits for an event to occur; that event may be a user clicking or moving the mouse, pressing a key on the keyboard, or an internal timer or interrupt. The listener is in effect a loop that is programmed to react to an input or signal.
Selection A generic term for a type of programming statement (usually an if-statement) that uses a Boolean condition to determine, or select whether or not to run a certain block of statements.
Global Variable A variable whose scope is “global” to the program, it can be used and updated by any part of the code. Its global scope is typically derived from the variable being declared (created) outside of any function, object, or method.
Event-Driven Program A program designed to run blocks of code or functions in response to specified events (e.g. a mouse clock).
Local Variable A variable with local scope is one that can only be seen, used and updated by code within the same scope. Typically this means the variable was declared (created) inside a function -- includes function parameter variables.
Concatenate To link together or join. Typically used when joining together text Strings in programming (e.g. “hello, “+name).
User Interface The visual elements of an program through which a user controls or communications the application. Often abbreviated UI.

4G 4G is a collection of fourth generation cellular data technologies.4G technologies are required to provide peak data transfer rates of at least 100 Mbps.
Algorithm A step-by-step list of instructions that allows you to complete a task.
List 13
Spyware Software that gathers user information through the user's Internet connection without his or her knowledge, usually for advertising purposes.
Mbps Stands for "Megabits Per Second." One megabit is equal to one million bits or 1,000 kilobits. Mbps is used to measure data transfer speeds of high bandwidth connections, such as Ethernet and cable modems. While "megabit" sounds similar to "megabyte," a megabit is roughly one eighth the size of a megabyte (since there are eight bits in a byte).
Permalink A permalink is the link to an individual blog post. You can Use the post name as the link display text.
https https is 'hypertext transfer protocol SECURED'. This means that the web page has a special layer of encryption added to hide your personal information and passwords.
browser A browser is a free software package that lets you view web pages, graphics, and most online content. Browser software is specifically designed to convert HTML and XML into readable documents. The most popular web browsers in 2016 are: Google Chrome, Firefox, Internet Explorer, and Safari.
Phishing and Whaling 'Phishing' is what modern-day con men do to defraud you of your personal accounts. Phishing is the use of convincing-looking emails and web pages to lure you into typing your account numbers and passwords/PINs. Often in the form of fake eBay web pages, fake PayPal warning messages, and fake bank login screens, phishing attacks can be very convincing to anyone who is not trained to watch for the subtle clues. As a rule, smart users distrust any email link that says "you should log in and confirm this".
Addons and Plugins Addons are custom software modifications. The user optionally installs addons to improve the power of their Web browsers or office software. Examples include: a custom eBay toolbar for your Firefox browser, a new search feature for your Outlook email. Examples include: Adobe Flash or Shockwave player, Microsoft Silverlight player, Adobe Acrobat pdf reader.
Trojan A trojan is a special kind of hacker program that relies on the user to welcome it and activates it. Named after the famous Trojan horse tale, a trojan program masquerades as a legitimate file or software program.
Spamming and Filtering 'Spam' has two meanings. Spam can mean 'the rapid repetition of a keyboard command'. But more commonly, spam is the jargon name of 'unwanted/unsolicited email'. Spam email is usually comprised of two sub-categories: high-volume advertising, and hackers attempting to lure you into divulging your passwords. Filtering is the popular-but-imperfect defense against spam. Filtering uses software that reads your incoming email for keyword combinations, and then either deletes or quarantines messages that appear to be spam. Look for a 'spam' or 'junk' folder in your mailbox to see your quarantine of filtered email.
Cloud Computing and Software-as-a-Service (SaaS) Cloud computing is a fancy term to describe that your software is online and 'borrowed', instead of purchased and actually installed on your computer. Web-based email is the most prevalent example of cloud computing: the users' email is all stored and accessed 'in the cloud' of the Internet, and not actually on their own computers. This is the modern version of the 1970's mainframe computing model. As part of the cloud computing model, 'Software as a Service' is the business model that claims people would rather rent software than actually own it. With their web browsers, users access the cloud of the Internet and log into their online rented copies of their SaaS software.
Enter text Encryption is the mathematical scrambling of data so that it is hidden from eavesdroppers. Encryption uses complex math formulas ('ciphers') to turn private data into meaningless gobbledygook that only trusted readers can unscramble. Encryption is the basis for how we use the public Internet as a pipeline to conduct trusted business, like online banking and online credit card purchasing. On the provision that reliable encryption is in place, your banking information and credit card numbers are kept private. Authentication is directly related to encryption. Authentication is the complex way that computer systems verify that you are who you say you are.
List 14
Ports and Port Forwarding 'Network ports' are thousands of tiny electronic 'lanes' that comprise your network connection. Every computer has 65,536 tiny ports, through which Internetworking data travels in and out. By using port management tools like a hardware router, users can control port access to better safeguard themselves against hackers. 'Port forwarding' is the semi-complex technique of opening specific network ports. You would port-forward to speed up your downloading and speed up your online connections for gaming and teleconferencing.
Firewall Firewall is a generic term to describe 'a barrier against destruction'. It comes from the building term of a protective wall to prevent the spreading of house fires or engine compartment fires. In the case of computing, 'firewall' means to have software and/or hardware protecting you from hackers and viruses. Computing firewalls range from small antivirus software packages to very complex and expensive software + hardware solutions. All the many kinds of computer firewalls offer some kind of safeguard against hackers vandalizing or taking over your computer system.
Archives Archives and Archiving A computer 'archive' is one of two things: a compressed container of multiple smaller data files, or a purposeful long-term storage of files that are not going to be used often. In some cases, an archive can be both. The act of 'archiving', similarly, is one of two things: to combine and squeeze multiple files into a larger single file (for easier emailing); or, archiving is when you will retire data and documents to be put into long-term storage (e.g. your thousands of old emails in your inbox).
Bug A bug is an error in a program that stops it from working in the way it should.
Debugging Debugging is the process of going through a program’s code to locate and fix a problem or mistake.

XML XML is eXtensible Markup Language, a cousin to HTML. XML focuses on cataloging and databasing the text content of a web page. XML commands look like the following: XHTML is a combination of HTML and XML
IM Instant messaging I.M. (usually spelled 'IM' without the periods) is instant messaging, a form of modern online chatting. IM is somewhat like texting, somewhat like email, and very much like sending notes in a classroom. IM uses specialized no-cost software that you install on your computer. That IM software, in turn, connects you to potentially thousands of other IM users through the Internet. You locate existing friends and make new friends by searching for their IM nicknames.
P2P peer-to-peer - Also known as "P2P". In a network the "peers" and separate computer systems that are connected through the internet allowing files to be shared directly from one computer system to the other without a central server. P2P file sharing ('peer-to-peer') is the most voluminous Internet activity today. P2P is the cooperative trading of files amongst thousands of individual users. P2P participants install special software on their computers, and then voluntarily share their music, movies, ebooks, and software files with each other. Through 'uploading' and 'downloading', users trade files that are anywhere from 1 megabyte to 5 gigabytes large. This activity, while in itself a fully legal pastime, is very controversial because thousands of copyrighted songs and movies trade hands through P2P. Read more about the controversial world of P2P file sharing...
Plugins Plugins are a special kind of web browser addon. Plugins are essentially required addons if you wish to view very specialized web pages. Examples include: Adobe Flash Player or Shockwave player, Microsoft Silverlight player, Adobe Acrobat pdf reader.
Intranet intranet - An internal or private network that is only available in one geographic location.
MP3 A popular compressed file format for digital music downloads.
Doc, Docx DOC - The file extension for a Microsoft Word Document. Note that in more recent versions of MS Word (after 2007) the file extension is DOCX.
List 15
Webcam webcam - A video camera used to broadcast streaming or still video using the internet.
Operating system The software that communicates with the hardware and allows other programs to run. (such as Windows XP, Windows 7, Apple OS X)
Spam spam - Unwanted and unsolicited "junk" email or irrelevant postings to a newsgroup or blog
Gateway A gateway is either hardware or software that acts as a bridge between two networks so that data can be transferred between a number of computers. For example, when you send an e-mail to a friend or when you log in to a Web site, there is a gateway that allows the connection take place. Often, your connection to a Web site will involve many smaller connections to other servers along the way. In these cases, a number of gateways are used. In a completely unrelated story, Gateway is also the name of a popular direct-order PC manufacturer.

404 Not Found Error The HTTP 404 Not Found Error means that the webpage you were trying to reach could not be found on the server. It is a Client-side Error which means that either the page has been removed or moved and the URL was not changed accordingly, or that you typed in the URL incorrectly.
website A location connected to the Internet that maintains one or more pages on the World Wide Web.
Domain Name Suffix A domain suffix is the last part of a domain name and is often referred to as a "top-level domain" or TLD. Popular domain suffixes include ".com," ".net," and ".org," but there are dozens of domain suffixes approved by ICANN. Each domain suffix is intended to define the type of website represented by the domain name. For example, ".com" domains are meant for commercial websites, whereas ".org" domains are to be used by organizations. However, since any entity can register domain names with these suffixes, the domain suffix does not always represent the type of website that uses the domain name. For example, many individuals and organizations register ".com" domain names for non-commercial purposes, since the ".com" domain is the most recognized.
cache The cache is a space in your computer's hard drive and in RAM memory where your browser saves copies of previously visited Web pages. Your browser uses the cache like a short-term memory.
