1. RAM – responsible for storing data and instructions that the CPU can access quickly during processing. 2. Components of a simple communication system – i. Sender ii. Receiver iii. Encoder iv. Decoder 3. Power Supply Unit – a component primary responsible for providing power to the other components of a computer system. 4. Advantages of LAN – Hardware such as printers can be shared; storage facilities can be shared; software and data files can be shared by many users. 5. Motherboard – acts as a bridge between the CPU and other components, allowing data and instructions to flow between them. 6. Design Process Stages – i. Design Brief ii. Creative Process iii. Planning and Execution, iv. Prototype or Dummy, v. Implementation 7. Simple Mail Transfer Protocol (SMTP) – protocol used for sending emails. 8. The function of router in a computer network – forwarding data packets to their destination. 9. Red, Yellow, Blue – primary colors in traditional color theory. 10. When a color is desaturated, it becomes less intense. 11. Higher amount of RAM – allows more applications to be open and run simultaneously without slowing down the system. 12. The purposes of packet switching – Allows for more efficient use of network resources by breaking data into smaller units called packets Networks are inherently robust and reliable It is often more cost-effective than circuit switching 13. The purposes of Internet Protocol – Defines rules and protocols for routing packets of data between source and destination Provides standardized protocol that enables devices from different manufacturers It assigns unique numerical addresses to devices connected to a network 14. Local Area Network (LAN) – type of network that is usually found in schools and businesses located in small geographical area. 15. Router  the device that acts as an interface between two networks.  the hardware device that acts as the traffic cop for network signals arriving at your home or business from your ISP. 16. Saturation – describes the intensity or brilliance of a color. 17. Form defines Space – the relationship between “Form” and “Space” in design. 18. https:// – URL schemes that indicates a secure connection. 19. Value – the intrinsic darkness or lightness of a color. 20. Temperature – a subjective quality related to warm or cool colors. 21. The rules for a good design – i. Have a concept ii. Speak with one visual voice iii. Use the one-two punch 22. Central Processing Unit (CPU) – component of a computer system is responsible for executing instructions and performing calculations. 23. Cache – component of a computer system is responsible for temporarily storing frequently accessed data to improve overall system performance. 24. Internet – a network of networks that connects computers worldwide via a huge set of telecommunications links. 25. Hypertext Transfer Protocol Secure (HTTPS) – a protocol commonly used for secure communication over the internet. This indicates that the web page has a special layer of encryption added to hide your personal information and passwords from others. 26. Primary function of the Basic Input/Output System (BIOS) in a computer system – initializes hardware components during startup. 27. The function of a motherboard in a computer system – managing communication between hardware components. 28. Hard Drive – a component of a computer system responsible for storing and retrieving large amounts of data over the long term. 29. The role of the Graphics Processing Unit (GPU) in a computer system – it processes video and image and frees up the CPU to perform other tasks. 30. Transmission Control Protocol (TCP) – implements flow control mechanisms to manage the rate of data transmission between sender and receiver. 31. Graphics Processing Unit (GPU) – component responsible for rendering images and graphics on a computer screen. 32. Network – a group of two or more computers linked together so that they can share resources and can communicate with one another. 33. When a computer runs out of RAM, it will begin to use hard drive space as a temporary form of memory. 34. Line – unites areas within a composition. 35. Role that the CPU play in a computer in a computer system – it processes input, store data, and output results. 36. The term “input device” in the context of a computer system – devices used to input data or commands into the computer. 37. A communication system is made up of hardware, software, and communication facilities. 38. The function of a modem in a computer network – converting digital signals to analog signals for transmission. 39. HTTP and HTTPS importance in internet applications – because they are protocols for transmitting information across the Internet. 40. Email – the most common method of sending and receiving messages online. 41. Channel – the physical path that connects sender and receiver in a communication system. 42. The computer will be able to process instructions faster if a computer’s CPU has high clock speed. 43. The primary function of a web browser – viewing and navigating websites. 44. The purpose of a firewall in a computer network – preventing unauthorized access. 45. Hue – the identity of the colors. 46. Website – one or more web pages and related content that is identified by a common domain name and published on at least one web server. 47. Hypertext Markup Language – a coding language used to tell browser how to place pictures, text, multimedia, and links to create a web page. 48. Web page – a document on the Web that is accessed in a browser. 49. Social media – websites and apps that allow people to share comments, photos, and videos. 50. Web application – an application program that is stored on a remote server and delivered over the internet through a browser interface. 51. Disadvantages of Web 1.0 –  read-only web  limited user interaction  lack of standards 52. Examples of Web 1.0 –  Mp3.com  Home Page Directories  Page Views  HTML/Portals 53. System Unit – a box that has electronic components to process information. 54. The information stored in RAM is erased when the computer is turned off. 55. ROM – function only when the computer first turned on or each time you restart (reboot) the computer. 56. Internet – a global network of thousands of computer networks linked by data lines and wireless systems. 57. Uniform Resource Locator (URL) – is a web address used to connect to a remote resource on the world wide web. 58. Bit – a single digit in the binary numbering system (base 2). For example: 1 is a bit or 0 is a bit. 59. Byte – generally consists of eight bits. 60. Upload – transfer data from your computer to another computer. 61. Download – transfer data from another computer to your computer. 62. Hypertext Transfer Protocol – the data communication standard of web pages. When a web page has this prefix, the links, text, and pictures should work correctly in a web browser.
