- pointing device that selects items and issues commands. f) Webcam - video camera used to capture
digital video. g) Speakers - produces soundwaves audible to human ear. h) Microphone - digitally
captures sound. i) docking station - connects a laptop to other devices, alternative to a USB.
12. Common input and output ports - ✔✔a) USB: Universal serial bus - connects storage and other
devices. b) HDMI: High definition multimedia interphase - connect media devices (sound and video).
13. Software - ✔✔instructions that enable a computer to perform tasks - apps and programs that
perform certain tasks.

ones available for online use + CDs and DVDs.
16. Social networking website - ✔✔allows users to connect and exchange status updates.
17. Mobile apps - ✔✔software programs designed to run on smartphones/tablets.
, 18. EULA - ✔✔End user license agreement : legal contract b/w buyer and manufacturer of the
software that allows the buyer to use the software but NOT copy or edit it. It preserves the rights of
ownership of manufacturer.

b) Freeware - free copyrighted software. c) Shareware - copyrighted software distributed on try-
before-you-buy basis but with limited functionality. d) Trial version software - copyrighted software
used for a restricted time only then users have to purchase it to use it further. e) Proprietary -
copyrighted software that must be bought before use. f) Bundled: comes w/ a new pc purchase. g)
premium: upon purchase of 1 license key, access to another programs is granted. h) public domain:
not copyrighted - allows users to access and alter source codes
20. Start computer and log on securely - ✔✔using username and password.
