BIS 121 IT for Business Application
Mid-term Revision
Part I – Computer Concept Four Basic Component of Computer
Input Process Output Storage Communication
Input device? Output device? Storage device? Communication device? Process device – CPU, RAM (primary storage)
Part I – Computer Concept (cont) System Unit (Process)
Central Processing Unit Perform the arithmetic and logical calculation Control the overall computer system Decode and Execute the program
Random Access Memory (primary storage) Store data and program (working space) when processing Volatile (loss data when power off) more expensive than secondary storage Access speed faster than secondary storage
Read Only Memory (ROM) Store start up programs (mouse , display driver) Non-volatile
Peripheral Device Input device + Output device + Storage Device
Storage Device Magnetic Optical Solid state device (e.g. USB) – no moving part
Part I – Computer Concept (cont) Binary digit (bit) – the smallest unit of storage 1 Byte = 8 bits
stores 28=256 different characters (ASCII) e.g. ‘A’,’?’,’8’
Chinese characters? – over 30,000 Chinese character
Kilo- 210bytes Mega- 220bytes Giga – 230bytes Tera – 240bytes
Part I – Computer Concept (cont) Software
Application software Word processing (MS Word) Electronic Spreadsheet (MS Excel) Presentation Software (MS PowerPoint) Database (MS Access)
System software Operating System (Window Vista, Linux) Utility Software (Anti-Virus, File Compression, File
explorer, Backup and Restore, Disk fragmentation)
Part II – Word Processing Main function
Format Text – Size, Font, Typeface (Bold, Italic, Underline, Superscript,….) Paragraph – alignment, line spacing, indent Bullets (,…)and Numbering (1,2,3…) (I, II, III …)
Spelling and Grammar Checking (cannot detect some misspelling- why?)
Find and replace function (why need to check the “whole word” checkbox?)
Page setting Size – width, height. Margin – left, right, top, bottom. Gutter (裝訂邊 )
Header and Footer – page number (why?), filename …. Tables
Row, column border, shading
Part II – Word Processing (Cont’d) Main function
Mail Merge Step 1: create main document (letter, envelope …) Step 2: create/open data file (word, excel, database) Step 3: insert merge field in suitable place of the letter. Step 4: Sorting and Filtering data if necessary. Step 5: Merge File / Print.
Long document Table of Content (TOC)
Step 1: Create/ Modify the default STYLES (Heading1, Heading2..) Step 2: Assign these styles to your document. etc, assign heading 1 to Chapter , assign heading 2 to Section … Step 3: Insert page number. Step 4: Perform TOC feature from Insert menu.
Footnote – can apply on each page or end of document.. Automatic reference – Table , Figure..
Part II–English Versus Chinese Word Processing
中文直書(V
ertical docum
ent O
rientation)
應用在中文文書
• Spelling and Grammar Check can only applied to English Word.
Use table to separatedifferent text orientation
Part III – Spreadsheet Main feature
Workbook contain worksheets Cells – Row (1,2,3…) + Column (A, B, C ….) Format – (Decimal place, $, %, ….) Formula - (+, -, *, /, ^) Functions
SUM MAX MIN AVERAGE SQRT
Part III – Spreadsheet (Cont’d) Main feature
Advanced Function If – IF(expression, true value, false value)
expression – “< , >, =, >=, <=, <>” Complex expression – Or, And. e.g And(expression1, expression2)
Countif – Countif(Cell Range, search value) Vlookup, Hlookup – search value from a lookup
table. vlookup(lookup value, lookup table range, row number, range) Hlookup(lookup value, lookup table range, column number, range)
Sorting and Filter – Manipulate data Sorting – Arrange the data in specific order by specific field
Field – single field or multi-field Filter – Filter the row which you want to cope with.
Filter function - >, < ,=, >=, <=, <>, and, or.
Part III – Spreadsheet (Cont’d) Main feature
Advanced Function (Cont) Subtotal – group some information e.g. count, sum,
average, etc Group field must be sorting first.
Relative reference and Absolute reference Relative reference – the cell reference in formula will
change when copying formula. e.g. A3 Absolute reference – the cell reference in formula will
not change when copying formula. e.g. $A$3 Mix-reference – e.g. A$3
Copy to right or left (change) BC… (no $ sign before A) Copy to up or down (no change) 3 ($ sign before 3)
Part III – Spreadsheet (Cont’d) Main feature
Protect worksheet – prevent to modify the data or formula accidentally Step 1: highlight the cells which can modify after apply
the protection to the worksheet Step 2: From format menu, click cell and select
protection, uncheck the lock option. Step 3: Perform the protect worksheet function in Tool
menu. Create chart
Type of charts Bar charts – compare the value in different sector Line charts –predict the trend of the value Pie charts – find the proportion of the different sector
Part III – Spreadsheet (Cont’d) Create chart (cont’d)
Step for create charts Step 1: highlight the cells which the information are
included in the chart; if the cells are not continuous. Hold down [Ctrl] key when select not continuous range cells.
Step2 : click the chart wizard to select the type of charts. Step3 : input the appropriate option of charts. Such as
chart title, labels and legend. Etc. Step4 : click OK for done.
Macro Automatic to do repetitive tasks Need to record the macro or write code Assign macro to hot-key or button to start the macro
