5 What is a Hardware?Hardware is any part of the computer system that is tangible. It works with the software to process data.
6 Computer CaseContains the major components of the computer. It helps protect them.
7 Monitor A display screen to provide “output” to the user. Function: view the information your are working on
8 MotherboardThe motherboard is a circuit board that is the foundation of a computerFunction: allows the CPU, RAM, and all other computer hardware components to function with each other
9 ProcessorThe CPU – The chip or chips that interprets and executes program instructions and manage the functions of input, output, and storage devices.
10 RAM Random Access Memory RAM is a computer’s temporary memory, which exists as chips on the motherboard near the CPU.Function: stores data or programs while they are being used and requires power.
11 ModemThe place where the computer is connected to the phone line.
12 Network CardA circuit board that connects the computer to the rest of the network usually using special cables.
13 Video CardConnects the computer to the monitor. It is a circuit board attached to the motherboardFunction: contains the memory and other circuitry necessary to send information to the monitor for display on screen.
14 Sound CardConnects the speakers and microphone to the computer.
15 CD Rom DriveThe drive that plays CDs and reads data that has been stored on the CD.
16 Floppy Disk DriveA device that holds a removable floppy disk when in use; read/write heads read and write data to the diskette.
17 Hard DiskMagnetic storage device in the computer.
18 KeyboardUsed to enter information into the computer and for giving commands.
19 MouseAn input device operated by rolling its ball across a flat surface.Function: used to control the on-screen pointer by pointing and clicking, double-clicking, or dragging objects on the screen.

21 Information Processing Cycle All computers follow the same basic operations: (1) input, (2) processing, (3) storage, and (4) output.
22 What is an Input Device?whatever is "put into" the computer to make it functionExamples: keyboard, microphone, mouse
23 What is a Processing Unit? manipulating whatever data has been input to transform it to informationEverything in the tower, motherboard, CPU
24 What is a Storage Device? A place where you can keep processed data.Examples: USB, Floppy disc, CD
25 What is an Output Device? resulting from processing inputs which is useable by humansExamples: monitor, speakers, printer

27 RAM Random Access Memory Represent primary storage or temporary storageHold data before processing and information after processing, before being sent to an output or storage deviceCan be read and written toVolatile- the contents are lost when the power goes off or is turned off
28 ROMRead only memoryCannot be written on or erased by the computer user without special equipmentContain fixed start-up instructionsContain instructions on start upNon volatile
29 Then, What is Software?Software- all the electronic instructions that tell the computer how to perform a taskApplication software helps the user perform specific tasksWord processing, presentation, database, electronic spreadsheetSystem software helps the computer perform specific tasksWindows, Mac OS X, Device driver software
30 Application Software Word Processing – working mainly with text Spreadsheet – used primarily with numbers & chartsDatabase – allows for entry of data in an organized manner, used for reportingPresentation – create presentations using projection devicesDesktop Publishing – used for creative design
31 Microsoft Office Application Software Word Processing- WordSpreadsheet- ExcelDesktop Publishing- PublisherDatabase- AccessPresentation- PowerPoint
36 Giving a presentation to the class on computers.
37 Writing a research paper on UFO’s. Word Processing
38 Creating an address book for Christmas cards. Database
39 System SoftwareSystem software are running processes on your computer. They are necessary features in order for your computer to run and do the things that computers are expected to do. For example: boot up, logging in, connect to the internet, etc.
40 Types of Personal Computers Desktopsmay sit on a desk or on the floor (a "tower")powerful enough to run everyday business and personal applicationshave separate hardware components for the computer, monitor, keyboard, and mouse.Laptopsnotebook computers,have all the functionality of a desktop computersmall and portableinclude a display, keyboard, and trackpad integrated into a single piece of hardwareSome laptops, called tablet PCs, recognize handwriting and allow you to work with a pen-like stylusNetbooks("Inter net note books)less powerful than traditional laptops, but as they are generallyused only for Internet-related activities such as and surfing the Webdo not need as much memory, processing power, or storage spacesmaller, lighter, and less expensive than fully-functional laptops.
41 Personal Digital Assistants (PDAs) handheld computers, PDAsfit in the palm of your hand. Whileless powerful than a desktop or laptop computer, a PDAincludes key productivity functionality like maintaining a calendar, address book and a to-do listhave Internet connectivity so you can send and receive and surf the WebSmartPhonescombines the functionality of a PDA with a cellular telephoneoften include photo and video capabilities
