Sub/Super-scripting (styles) Footnote refs are super scripted Math uses a lot of sub scripts Note 2: operations performed 1. The subscript or superscript format 2. The size reduction

Word Art Copy/Cut and Paste Copy puts selected data on the clipboard Cut puts selected data on the clipboard and removes it from the original place Past duplicated the clipboard data into the document at the cursor position Copy leaves the original where it was Control x – cut Control z – undo, puts back into place Basic layout of a document (Page Setup) Header Body of document On left & right side (margins) Bottom of page- Footer Specify a bottom margin at least as tall as your footer text, to prevent clipping Then adjust the placement of the footer up or down inside the margin.

Breaks Three kinds: 1. Section 2. Page 3. Column Indicates where computer should eject the page (org change formatting rules). Appears as a “dotted line” on monitor To go to next page – Insert page break Indents This paragraph has a hanging indent. Note how all the lines after the first are indented. This style is usually seen with bulleted or numbered paragraphs. 1st line indent. This is how you learned to write in high school. See the empty space on line 1. Here’s a bulleted paragraph, so you can see how the program indents the text for you.

Hint. In MS Word, Shift+Enter = new line + keep in paragraph Triple click – select whole paragraph Justification Left Aligned, Right Aligned, Centered Tabs Different from typewriter tabs Tab key inserts a tab character Format/tabs set positions 4 major types: Left align Right align Center Decimal

Footnotes 2 Kinds 1. spot references such as this one ^aha 2. Numbered, like this one^2 User chooses spot characters

Headers and Footers Print on EVERY page of a section May contain - Raw text - Symbols - Fields Fields change when their sources change - File and data info - Author info - Page number Section 2: Hardware and Operating Systems An electronic device that can: - Store a set of instructions for later use - Accept input - Process the input by following the stored instructions - Output results How do they work? Based on switches on/off where: - On represents a 1 - Off represents a 0 All data is represented by this code of ones and zeroes There is a code for every printable symbol and for some non-printables, like the space and some control values. Apply

Printers print 1 character for each 8-bit code Example: Sent to printer 01110000 01010000 00110000 00110001

printer prints p P 0 1

Binary 0 and 1 Decimal 0-9 The AMERICAN STANDARD CODE FOR INFORMATION INTERCHANGE – ASC2 code

Current PC Operating System Uni-programming  DOS- Disc Operating System Multi-Programming  UNIX, Linux  Mac OS/X  OS/2  Windows XP, Vista, 7, and several Server Versions January 31 OS Concept 

Multi- programming

Hard disk drive uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter. Hard disk refers to the data storage elements themselves. Solid state drive – has no moving parts Volatile memory is also called as temporary memory as it will hold memory temporarily. Non-Volatile Memory: A device which can hold data in it even if it is not connected to any power source is called Non Volatile Memory. The typical examples for Non Volatile Memory are your Hard drives and flash drives.

Multi-programming  Several whole programs running “concurrently’ Multi-tasking  Several parts of a program running Concurrently  Not required for multi-programming Concurrently means “apparent concurrency”

A File Any Kind of Document  A letter  A calendar  A balance sheet  A photograph  A game  A chapter of a book or a whole book  A computer program  A screen saver

Folders and Directories A (possibly empty) collection of files A folder may contain other folders and files The root directory: highest-level folder  Has no name  Always exists on every formatted disk  Represents by the “\” character File Identifieers (or Descriptors) Old DOS Style: 1-8 characters [. 1-3 characters] New Window 95 Style: up to 255 characters Cannot contain: \ /: ? ”< > | Examples: AB.X My Diary.doc Team Plays-98.doc Subdirectories have an arrow pointing down

Hardware, word processing, operating systems (TEST) Current Directory

BAT Files Sequence of command invocations and comments Save time/effort Provides user-tailored automation Computer Viruses 1. Modify or hide inside a program or file 2. Do malicious acts  Erase disks, lockup machine, dial long distance, and make PC unbootable 3. Detectable (and often removable) by virus-checker programs 4. Trojan Horses, macros, worms, scripts Beginning of Exam 2 Spreadsheet Layout Foreman’s Laws 1. Print row and column headings (page setup) 2. Print both the normal and formula views for EVERY spreadsheet printed Don’t worry about text cutoff in formula view 3. Plain numbers are not allowed in any formula. Even if shown in the books or slides (Example: =A1+3 is incorrect, because “3” is a number, regardless of its meaning) Some Hints  Dates appear as numbers in formula view 10/26/00 appears as 36825  A column that is too narrow will display ###. Just widen the column to see the number. A note about the slides In many slides, you will finds that one of Foreman’s laws is broken. Ranges

Methods for specifying more than one cell to be worked with at a time Consists of 3 things:  The start cell  A separator  The end cell Examples:  B11:E14  E8.C5  A1, B3, Z4 A Row Range – D1:D3 or D3:D1 A Rectangle Range – D2:F3 (diagonally opposite corners) A List – disconnected cells, optionally with other ranges, in any order, spereated by commas Where do I put the Formula? In the cell where you want the answer Switch between Normal View (shows all answers) Formula View (shows all formulas)...
