Practice
Lecture Hands On Textbook Homework Exam
This structure requires your effort
You see things for the first time in class
You practice the things with hands on
Then you study and do homework on your own

10. Students say discussion is helpful…
It really makes you realize exactly what mistakes you are making and sometimes you don’t feel as bad if you are wrong because
you can see that fellow classmates think the same way.
Discussion is really helpful as sometimes when you get lost in other classes, you are lost for the rest of the lecture. Discussion and clicker questions help make students realize when they are getting confused before it is too late and the discussions with classmates helps get us back on track

11. Your Tasks Homework: 45% Concept Exam: 5% Word Exam: 15%
Excel Exam: 15%
PowerPoint Exam: 5%
Final Exam: 15%

Partly from the book
These are the best way to prepare for the tests
I will post the homework assignments in the course webpage:

13. Grading
Following is a rough guide to how course grades will be established, not a precise formula
Grading is on a 12 point scale -- A through F
93-100% : A
90-92%  : A-
87-89%  : B+
83-86%  : B
80-82%  : B-
77-79%  : C+
73-76%  : C
70-72%  : C-
67-69%  : D+
63-66%  : D
60-62%  : D-
0-59%    : F

14. Academic Honesty Don’t cheat.
Cheating on a test will get you an F in the class and no option to drop, and a visit with your college dean.
Cheating on homeworks means you don’t have to turn them in any more, but you don’t get points either. You will also take at least 25% penalty on
the exam grades.
Copying solutions of the internet or a solutions manual is cheating.
Review the EU student handbook or policy
When in doubt, ask.

22. Software
Software is a program which designed to make use of various devices on the computer.
A) Brain = CPU B) Memory(Conscious) = HDD C) Memory(Subconscious) = RAM D) Senses = Input Devices
E) Speech = Output Devices F) Food = Power  G) Soul = ? L.H.S= sum(A+B+C+D+E+F) = Human
{Body + Soul = Human}
Similarly {Hardware + Software = Computer}

23. Software Two major kinds of software
System Software – Microsoft Windows
Linux (& its distrubutions)
Mac OS X
Windows 7
Windows 8
What are the different version of Windows?
Application Software – Microsoft Office
Core applications – Word, Excel, Access, and PowerPoint
Personal Information Manager – Outlook
Other applications – Skype and Web Browser
The difference between operating systems and application software needs to be discussed. Key terms and ideas include:
Operating System - the software that controls the execution of all applications and system software programs.
Word Processing - software used to enter, store, manipulate, and print text.
Spreadsheets - software that permits users to work with rows and columns of data.
Databases - software used for record-keeping.
Presentation - software that allows users to create visually appealing presentational graphics and information.
Antivirus -a program that can automatically detect a virus when one appears on the computer system.

Other differences

38. Computer Hardware Four basic categories of equipment: - System Unit
- Input/Output
- Auxiliary Storage
- Communication

39. System Unit
Two main parts:
- Processor
- Memory

40. The Processor Original chips were numbered
8086, 80286, 80386, 80486
You could buy chips from multiple vendors
Intel trademarked its chip as the Pentium
Pentium II, Pentium III, Pentium IV
Clock speed (MHz or GHz) differentiates chips
Dual Core, Quad Core
The central processing unit (cpu)

41. Memory (AKA RAM) Most common type of primary storage
Stores program instructions and data temporarily
Memory locations have unique addresses
Volatile—disappears when power is turned off
Students need to understand the differences between RAM and permanent storage.

42. Input/Output Common input devices are the keyboard and the mouse
Others?
Common output devices are printers and monitors
Others

43. Auxiliary Storage
Unlike memory, secondary storage holds data and programs even if electrical power is not available

44. Auxiliary Storage Hard (fixed) disk 1 TB and higher Removable storage
CD-ROM
CD-R/CD-RW
DVD/DVD-R/DVD-RW
Tape (common for backups)
Flash Drives & SD Cards
Outdated
Zip disks
Floppy Disks
Floppy Disk - a thin interchangeable disk for secondary data storage.
Zip Drive/JAZZ - a storage device that uses optical technology together with magnetic technology to read and write to an interchangeable floppy-size Zip disk.
Hard Disk - a permanently installed, continuously spinning, magnetic storage medium made up of one or more rigid disk platters.
CD-ROM disk- a type of optical laser storage media. A CD-ROM can hold up to 650 MB.
DVD (Digital Videodisk) - just like a CD-ROM, but can store up to 17GB.
Tape Backup - a secondary storage medium for sequential data storage and backup.
Access Time - the time interval between the instant a computer makes a request for a transfer of data from a secondary storage device and the instant the operation is completed.
Disk Sector - a disk storage concept of a pie-shaped portion in which records are subsequently stored and retrieved.
Read/Write Heads - component of a disk drive or tape drive that reads from and writes to its respective secondary storage medium.

45. Bits
A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively.
1 byte: 8 bits
a single ASCII character, like "h"
1 kilobyte (KB): 1,024 bytes
1 megabyte (MB): 1,024 KB
1 gigabyte (GB): 1,024 MB

46. Bits 1 terabyte (TB) is 1,024 GB 1 petabyte (PB): 1,024 TB
1 exabyte (EB): 1,024 PB
