2 Copyright 2013 by Janson Industries 2 Objectives n Explain u Steps to success in this class u Basic computer concepts u Computer system ► Hardware ► Software ► Categories u Applications u User types

3 Copyright 2013 by Janson Industries 3 Class Success n Take good notes and read the book before you come to class u Suggestion: print out PP and use as basis for notes n A memory stick u Put a file called IFFOUND or ICE with some contact info in it ► For when you lose it ;-) n Organize your work. Pay attention to file: u Naming u Location

4 Copyright 2013 by Janson Industries 4 User Ids and Passwords n If you want to use the lab computers you will need to know your FSCJ user id and password n User ids are usually the first 4 letters of your last name, followed by first and middle initial u John Quincy Adams user id would be: adamjq n If it doesn’t work, call the FSCJ Help Desk u

5 Copyright 2013 by Janson Industries 5 Class Software n If you want Access (DBMS which is needed for a class assg) for free u Send your name and FSCJ address to me by the end of the week at: ► n An organization called DreamSpark will contact you with further info

6 Copyright 2013 by Janson Industries 6 Class Software n As a student you can get a free copy of Office 365 n This is the FSCJ blog link with the tutorial: u 2013/12/05/students-microsoft- office-for-free/.

7 Copyright 2013 by Janson Industries 7 Tests n If you are late for a test, you will only be able to take it if no other student has left the room n If you cannot make a test, you must arrange a make up before hand n If an emergency arises you, must contact me and arrange for a makeup u You cannot show up to the next class and expect to take a make up

8 Copyright 2013 by Janson Industries 8 Concepts n Computer u Electronic device that processes data into information according to specific instructions n Data: r aw facts u Can be text, numbers, images n Information: useful/meaningful knowledge

9 Copyright 2013 by Janson Industries 9 Data vs. Information n Data processing u Selection u Sorting u Summarizing u Information Retrieval u Updating

10 Copyright 2013 by Janson Industries 10 Data vs. Information n QBs plays: u 1 st incomplete u 2 nd 4 yard left side pass u 3 rd run 6 yards u : : : : : u 95 th interception n Raw facts: how well did the QB play? n What if data processed into info: u 72% completion for 288 yards u 3 interceptions

11 Copyright 2013 by Janson Industries 11 Information n QBs data for day vs. night: n What if instead processed into: Game1pm/4pm/NightPassing YdsCompletion % N :: : : # Games1pm/4pm/NightAvg Passing YdsCompletion % N16661

12 Copyright 2013 by Janson Industries 12 Processing InputOutput n Information processing cycle n Computer can store input and output Concepts Storage

13 Copyright 2013 by Janson Industries 13 Concepts n Input comes in two forms: u Data u Instructions n Hardware (h/w): the computer machinery n Software (s/w): group of instructions u Like a recipe

14 Copyright 2013 by Janson Industries 14 Hardware Device Categories n Input device: converts human understandable input into machine understandable input n Processing device: converts input into output n Output device: converts machine understandable output into human understandable output n Storage device: reads and writes input or output to a storage media

15 Copyright 2013 by Janson Industries Input Device Keyboard Microphone Scanner Mouse 15 Processing CPU InputOutput n Computer Hardware Concepts Storage Device Hard drive Thumb drive CD/DVD drive Memory card slot Input Output Device Printer Monitor Speakers Output

16 Copyright 2013 by Janson Industries 16 Concepts n External vs. Internal Storage u Internal also called Main Memory or RAM n Many differences between the two u Speed, capacity, persistence n For now, key difference is, that MM managed by CPU u External memory has a separate device that manages the media

17 Copyright 2013 by Janson Industries Input Device 17 1 Run Word n How Internal and External memory work with application s/w Concepts Storage Device Run Word CPU 2 Copy of Word RAM 3 Word

18 Copyright 2013 by Janson Industries 18 Concepts n Communication Devices u Enable computers to send and receive input and output to other computers u Example: Modem n Input and output sent over a "line" (transmission media) u Phone line, cable, wireless n A group of linked computers is called a network

19 Copyright 2013 by Janson Industries 19 Network n Network hardware consists of u Transmission media u Communication device(s) u User nodes n Television network? n Phone network? n Computer network?

20 Copyright 2013 by Janson Industries 20 Internet n Transmissions over the common carrier networks u Phone, cable, satellite and computer networks n...that follow the rules of TCP/IP n WWW is one part of the Internet that sends information as web pages

21 Copyright 2013 by Janson Industries 21 Concepts n Software (instructions) consist of many programs n Types of Software u System ► Enables the computer to work ► Provides basic functions for applications ► Enables the computer to work more efficiently u Application ► Perform user functions
