1. source code ANSWER any collection of computer instructions, possibly with comments, written using a human-readable programming language, usually as plain text; contains variable declarations, instructions, functions, loops, and other statements that tell the program how to function 2. SQL ANSWER Structured Query Language - used to communicate with a database 3. SSL ANSWER Secure Sockets Layer - a standard security protocol for establishing encrypted links between a web server and a browser in online communication; ensures that all data transmitted between the web server and browser remains encrypted. 4. table ANSWER an arrangement of information in rows and columns containing cells that make comparing and contrasting information easier 5. upload ANSWER transfer a file or program to a central computer from a smaller computer or a computer at a remote location 6. URL ANSWER universal resource locator-the address of a web page on the world wide web 7. variable ANSWER A placeholder for a piece of information that can change. 8. vector ANSWER a type of array that is one dimensional; a logical element in programming languages that are used for storing data 9. webpages ANSWER a document commonly written in Hyper Text Markup Language (HTML) that is accessible through the Internet or other network using an Internet browser 10. computational thinking ANSWER thought processes involved in formulating a problem and expressing its solution(s) in such a way that a computer— human or machine—can effectively carry out 11. cyclical redundancy check ANSWER a code added to data that is used to detect errors occurring during transmission, storage, or retrieval 12. data models ANSWER the analysis of data objects and their relationships to other data objects. Often the first step in database design. 13. database relationships ANSWER a situation existing between two relational database tables; one table has a foreign key that references the primary key of the other table. Relationships allow relational databases to split and store data in different tables, while linking disparate data items 14. decryption ANSWER process of taking encoded or encrypted text and converting it back into text that you or the computer can read and understand. 15. defragmentation ANSWER process that reduces amount of fragmentation by physically organizing the contents of a mass storage device into the smallest number of contiguous regions (fragments). 16. direct access ANSWER retrieving data immediately from any part of a computer file without having to read the file from the beginning. 17. Easy Cache ANSWER takes real-time snapshot of every page, post, category, link, etc. Snapshots are then stored (cached) into folder of your choice, so they can be referenced and served to the visitor later, in order to save database processing time that has been slowing your website down. 18. encryption ANSWER activity of converting data or information into code 19. ethernet ANSWER a network protocol that controls how data is transmitted over a LAN (local area network) 20. field ANSWER a set of characters comprising a unit of information 21. flowchart ANSWER graphical representation of a computer program in relation to its sequence of functions (as distinct from the data it processes) 22. hierarchy ANSWER ranks components in terms of response times, with processor registers at the top of the pyramid structure and tape backup at the bottom 23. hotspot ANSWER a wireless LAN (local area network) node that provides Internet connection and virtual private network (VPN) access from a given location 24. looping ANSWER a sequence of instructions that is continually repeated until a certain condition is reached 25. markup languages ANSWER the language of the web - include HTML, XML, and XHTML - all of which have some things in common 26. matrix ANSWER a set of numbers laid out in tabular form (rows and columns). From this meaning, a less formal meaning is derived of a complex collection of lines intersecting at right angles 27. metacognition ANSWER thinking about different possible ways to solve a problem and choosing the best possible solution 28. microprocessor ANSWER integrated circuit semiconductor chip that performs the bulk of the processing and controls the parts of a system
