BTE 210 FINAL EXAM- PEREZ/study guide verified 100% BTE 210 FINAL EXAM- PEREZ/study guide verified 100% hardware - correct answers-the physical components of a computer system; you can touch, see, and feel software - correct answers-a set of machine readable instructions that directs a computer's processor to perform specific operations; developed by writing instructions in programming language, creating a "program"- that control the operation of the hw and processing of data computer system - correct answers-hw which operates under the control of a sw; computer hw and sw require each other and neither can be realistically used without the other central processing unit (CPU) or microprocessor - correct answers-carries out the instructions of a computer program and it is the primary component that executes the computer's functions; present in every computer system; the more processing power the faster the computer system will produce output ex- Intel, AMD, MICRON, etc. main memory or random access memory (RAM) - correct answers-stores instructions and data that is needed by the CPU now; present in every computer system; volatile (non-permanent) ; performs extremely fast read and write functions; always inside computer system secondary storage - correct answers-required to permanently store programs and data, that is passed to main memory, when CPU requires them; non-volatile; stores more than main memory (although cheaper by Gb) types: hard drives (hard disk) - principal means of data storage on most computers; optical drives; flash drives input devices - correct answers-hw that receives data from users ex: keyboards, mouse, joystick, touchpad, stylus, biometric scanner (fingerprint), trackball, magnetic strip reader (ATM/POS), barcode scanners, scantron, RFID reader, .etc output devices - correct answers-hw that conveys info to a user or another computer ex: monitors, screens, printers, plotters, speakers, projectors, etc. system sw: operating system - correct answers-the main system control program; required in ALL computers; supervises overall operations (allocates CPU time and main memory to programs); provides interface b/tween any other sw and the hw ex: iOS, Android, Windows, Mac OS X, Linux graphical user interface (GUI) - correct answers-interface through which a user interacts with electronic devices such as computers, hand-held devices and other appliances through icons, menus and other visual indicator (graphics) representations to display info and related user controls; representations are manipulated by a pointing device i.e a mouse, trackball, stylus or finger on touch screen system sw - correct answers-security, database management systems, programming languages security - correct answers-Symantec; mcafee database management systems - correct answers-oracle; ms access; ibm db2 programming languages - correct answers-python; c++; r application software - correct answers-a set of one or more programs designed to carry out operations for a specific application enterprise resource planning (ERP) systems - correct answers-provide communication among functional areas in a business (i.e.- sales, hr, etc.) ex: sap, jd Edwards, quickbooks, sage transaction processing systems (TPS) - correct answers-support the "real time" monitoring, collection, storage, and processing of data from the organization's day to day operations ex: ATMs, time and attendance (Kronos), Fedex or ups delivery, dorm entrance inter-organizational systems - correct answers-automated info systems shared by more than one organization and allowing info flow across organizational boundaries, improving processes supply chain management (Walmart) software licensing - correct answers-most commercial software is copyrighted; copyright laws; proof of purchase; can't be resold dematerialization - correct answers-increasing complexity of sw open-source software - correct answers-software made available in source code form at no cost to developers and users; source code always available to general public with relaxed or non-existent copyright restrictions; often developed in a public, collaborative manner augmented reality - correct answers-a type of interactive, reality-based display environment that takes the capabilities of a computer generated display, sound, text and effects to enhance the user's real world experience; combines real and computer-based scenes and images to deliver a unified but enhanced view of the world; primary objective is to provide a rich audiovisual experience employing computerized simulation ex: healthcare: veinviewer, augmedics; education, marketing: aurasma, houzz virtual reality - correct answers-computer-generated environments or realities that are designed to simulate a person's physical presence in a specific environment that is designed to feel real; purpose- allow person to experience and manipulate the environment as if it were the real world i.e.- to completely immerse servers - correct answers-a computer that is dedicated to carry a specific task (processing) and 'serves' the result to 'client' systems, through networks; whenever computers share resources with client machines they are considered servers; ex: supercomputers, mainframes, midrange or distributed systems fat client - correct answers-desktop, laptop; more processing power/memory/data storage, less dependency on server, runs more sw in offline mode thin client - correct answers-mobile, wearable, embedded; limited processing power, less memory/data storage, very light weight equipment, very dependent on server to run sw/network (internet) dependent computer network - correct answers-two or more computing devices connected to one another to establish communication and share resources; uses a common network protocol (Ethernet/TCP/IP) to share info and resources with each other; network transmission medium may be fiber optics, microwave, infrared or even communication satellites; area covered could expand from 1 room to the world; comprised of hw and sw devices bandwidth - correct answers-transmission capacity of a network (rate of data transfer); units- bits per second (bps) broadband - correct answers-telecommunications signals of greater bandwidth; based on FCC definition- connection speeds of at least 25 Mbps downstream and 3 Mbps upstream personal area network (PAN) - correct answers-computer network organized around an individual person within a small office or residence; very short range (few meters), typically includes 1 or more computers, smartphones, printer, video game consoles, wireless speakers, and other personal entertainment devices local area network (LAN) - correct answers-consists of a computer network at a single site, typically a limited area like an individual office building or warehouse; smallest- may only use 2 computers, larger- can accommodate thousands of computers; typically relies on wired connections, ethernet cables, for increased speed and security, but wireless connections can also be part of it; data and files are shared without the need for encryption metropolitan area network (MAN) - correct answers-computer network across an entire city, college campus, or small region; larger than a LAN (typically limited to a single building or site); can cover an area from several miles to tens of miles; often used to connect several LANs together to form a bigger network wide area network (WAN) - correct answers-network that covers a very large geographic area, such as an entire country or the entire world; can contain multiple smaller networks, such as LANS/MANS; large bandwidth capacity, provided by common carriers; Internet- best-known example of public WAN the Internet - correct answers-type of WAN- huge network of networks; collection of infinite number of connected computer devices that are spread across the World; distributed network (no central agency owns/manages); cost shared among nodes and nodes must pass the d
