WEEK 15 INSTALLATION OF BASIC SOFTWARE

INSTALLING WINDOWS OPERATING SYSTEM(WINDOWS 7 IN 2007)
It is important to understand that this guide was specifically designed for a lab
environment. There are a lot of operating system vulnerabilities that are intentionally left
unpatched in these installation steps. This is intentionally done to give you the best
results when completing the labs and tutorials in this book. If you are interested, a great
reference for building a Windows 7 Professional box that is secure enough for a
production environment is Windows 7.
To create a properly configured laptop for the Security Essentials Boot Camp, follow the
detailed steps in this document—from the initial setup screen to the final login. This
guide was designed for use on a system that doesn't already have a Windows platform
installed on it. If your machine does not have a blank hard drive, some of the screens you
see at the beginning of the installation may be different from what you see in this chapter.
If different screens appear, it is important that you always choose the option to replace,
or overwrite. Do not choose to upgrade. The Windows install should also be placed in the
default c:\windows directory.
Creating Boot Disks
If your system does not support the capability to boot off of a CD-ROM, you can use the
Windows 7 boot disk to boot. If you do not have a set of the four disks, you need to use
a machine that already has Windows 7 Professional installed on it. The following steps
show you how to create the four boot disks:
1. Label four blank, formatted, 3.5-inch, 1.44-MB floppy disks as: Setup
Disk One, Setup Disk Two, Setup Disk Three, and Setup Disk Four.
2. Insert Setup Disk One into the floppy disk drive of a Windows or DOS
system.
3. Insert the Windows 7 CD-ROM into the CD-ROM drive.
4. Click Start, and then click Run.
5. In the Open box, type D:\bootdisk\makeboot a: (where D: is the drive
letter assigned to your CD-ROM drive), and then click OK.
6. Follow the screen prompts.
7. After you have completed the screen prompt requests, insert Setup Disk
One into the floppy disk drive of the lab PC and power the PC on.

WEEK 12-14 SREADSHEET

SPREADSHEET

Is a general-purpose electronic spreadsheet used to organize,
calculate, and analyze data. The task you can complete with Excel ranges from
preparing a simple family budget, preparing a purchase order, create an elaborate 3-D
chart, or managing a complex accounting ledger for a medium size business.
 ROWS AND COLUMNS:

SPREADSHEET BASICS:
You can get help from Excel in learning the parts of the spreadsheet. With the mouse pointer click on the
Help menu, scroll down and click on “What’s This?” The cursor will become a Question Mark and you can
click on any part of the toolbar to learn more about it. Using the Question Mark Cursor, find the Formula
Bar and click on it. Observe the difference between the cell contents and the Formula B

FORMULAR IN SREADSHEET
=SUM (D2:H2)
=COUNTA(B2:E2)
=MAX (F1:F4) 
=MIN(B4:B6)
=AVERAGE(T2:T4)
=RANK(B2,$B$2,:$B$11)
 =IF(D2="OFFICER",25%*E2,10%*E2)
=IF(B3="A",5,IF(B3="B+",4,IF(B3="B",3,IF(B3="C",2,IF(B3="D",1,0)))))

WEEK 9-11 WORD PROCESSOR



 WORD PROCESSOR

Is word processing software that allows users to create and edit text documents. Users can start with blank documents or work from pre-configured templates for projects with frequently used formats.Also known as WORD PROCESSOR

THE TABS
The tools of Microsoft Word are organized under the tabs HOME, INSERT, PAGE LAYOUT, REFERENCES, MAILINGS, REVIEW, and VIEW.

HOME
The Home tab includes the most common tools used for creating a document. Often you will find yourself using nothing but this tab.

The INSERT tab is used for plugging tables, pictures, and other goodies into your document
ILLUSTRATIONS is the field where you can find tools to help you find or create a graphic to plug into your document. CLIP ART will allow you to browse from a set of images included in Microsoft Word and PICTURE will let you explore your computer for personal photos.

Insert mail merge fields

When you start your email merge, label merge, or letter merge and connect your document to your mailing list, you can add mail merge fields to personalize the content. The merge fields come from the column headings in your mailing list (also known as your "data source"). Here’s an example of how fields in an Excel mailing list appear in your mail merge document.

WEEK 5-6 BASIC LINUX OPERATION




Multi-user & Multi-process

Many people can use one machine at the same time.

File & Process

Data, directory, process, hard disk etc (almost everything) are expressed as a file.

Process is an running program identified by a unique id (PID).
 

Important Directories

/bin     This contains files that are essential for correct operation of the system. These are available for use by all users.

/home This is where user home directories are stored.

/var  This directory is used to store files which change frequently, and must be available to be written to.
etc    Various system configuration files are stored here. 

Commands

 su  switch user

passwd   change password

useradd  create new user account

 userdel  delete user account

mount  mount file system
 

WEEK 4-5 WORKING IN MICROSOFT WINDOWS ENVIRONMENT

The Desktop
The Desktop is the main Windows 7 screen (see image below). It is the work area where dialog boxes, windows, icons,
and menus appear. Like an office desk, the Windows 7 desktop contains items you can use to do your job. For
instance, from your desktop, you can perform file-management tasks and run software applications. You can
customize the appearance of the desktop to suit your preferences

Start Menu Basics
The Start Menu is, appropriately enough, your starting point in Windows 7. All of your programs, settings, etc. can be
accessed here. To begin using it, click the Windows Icon button in the bottom left corner or press the Windows key on
your keyboard. Here are some common items you’ll use on the Start Menu.

VIRTUALIZATION OF OPERATING SYSTEMS

What is Virtualization?

OS virtualization
Create a platform that emulates a hardware platform and allow multiple instances of an OS to use that platform, as though they have full and exclusive access to the underlying hardware
 
Virtualization – Why?
Server Consolidation 
Often many servers support 1 major application 
Strong isolation between VMs 
Virtualization saves on hardware & energy 
Disaster Recover
 High Availability 
Testing and Deployment
