1. Any part of the computer system, including memory, storage devices, and the microprocessor

2. Software that secretly gathers info from your computer and then sends this data to the company or person that he created; this may be installed by a virus, though it may also be installed along with other software without the users permission or knowledge

3. When you purchase USB cables, pay special attention to the type of USB your device requires. The USB specification has evolved over the years, resulting in a wide array of speed and capabilities. USB 1.1, introduced in 1998, supports a data rate or speed of 12 Mb per second (Mbit/s). In 2000, USB 2.0. increased that to 480 Mb per second. The release of USB 3.1, in 2013, further increase it to 10 Gb per second (Gbit/s), allowing full quality transmission of audio and video data. Also make sure you purchase the right connector for your device. Common connectors include type a comma type B, micro a, micro B, and older mini-a and mini-b. There are even USB 3.0 type a, type b, and micro b connectors. The most recent, Type C, features a plug that can be inserted both ways.

4. Helps analyze, optimize, configure, and maintain a computer. Examples of utilities include antivirus software, back up tools, and disc tools that allow you to analyze a hard drive or compressed started to save space. As you learned in the discussion of hardware ports, device drivers handle the transmission protocol between a computer and it's peripherals. When you are a new device to computer, the installation process typically involves loading a driver that updates the computers configuration.

5. Essential, establishing the communications protocol is that will be observed on the network and controlling the data 'traffic flow'

6. Microsoft windows, used on many personal computers, and OS X, used exclusively on apples Macintosh computers are referred to as this because they provide a graphical user interface that acts as a liaison between the user and all of the computers hardware and software

7. Have a hinged lid that contains the computers display and the lower portion that contains the keyboard. These are also called notebook computers and are powered by rechargeable batteries, and they easily slip into a bag or briefcase. Ultraportable computers are smaller and generally less powerful

8. Using a password and username to go into your account and off of your account

9. Number of pixels the monsters please in each dimension, typically expressed as width x height; common standard resolutions range from 640 x 480 to 5125 x 2880

10. Essentially, a robot that deposits multiple layers of material typically heated plastic onto a surface. To achieve the desired shape, the tool head made travel in a different direction as each layer is applied. A designer may use one to create Prototypes of new products, or doctor could print prosthetic limbs. 3-D bio printers could someday be used to create living tissue or replacement organs

11. Advances mean that people with physical impairment or disabilities can use computers. For example, people who cannot use their arms or hands operate a mouse may be able to use food, head, or I movements to control specialized assistive device. Does the poor vision can use keyboards with large keys, screening orders that can increase the size of objects on a moderate, or screen readers that speak on screen content allowed. Experiments involving neural implants are already allowing people with disabilities to control robotic limbs

12. The data or set of instructions to give to a computer

13. The place were a message is sent over to, such as a telephone or coaxial cable, or wirelessly

14. Software which allows you to manipulate digital photos; you can make images brighter, add special effects, or crop photos to include on the important parts of the image. Examples include Microsoft photos and adobe Photoshop

15. Popular printers from home and small business use. These printers spraying onto paper, producing quality comparable to that of a laser printer, though at much slower speed. These printers can also print on the white variety of paper types, the use of plain paper may result in fuzzy text. Most sold today print in color, and the excel at producing photos with smooth color, especially when using special glossy photo paper.

16. Millions of cycles per second

17. An electronic message sent from one person to another, is one of the oldest and most basic forms of Internet communication. Your company may provide email service, or you might use a service such as Microsoft outlook.com or Google email. You can share document or images with coworkers and friends by sending them as attachments to email messages.

18. Uses short range radio waves of up to about 30 feet to connect devices wirelessly to one another or to the Internet. It is often used to connect wireless headsets to sell phones or computers, and for connecting some wireless pointing devices and keyboards

19. The kind of file you created when you use software; for instance, a report that you write with a wordprocessing program is data, and it must be saved as a file if you want to access it later

20. Electrical paths

21. Address on the web

22. Older than HDMI and DVI, only allows analog transmission of video

23. The place were processing tasks occur; the main electronic component inside the computer; also called a circuit board and typically contain processing hardware such as microprocessors and cards

24. Not where used to translate a scanned text document into text that can be edited in wordprocessing program. If you scan the photo, it can be saved as an image file

25. A collection of information organized in a uniform format of fields and records; the online catalog of books and library is a database that contains Fields that identify the title, the author, and the subject under which the book is classified
