Session 1 : What are all the transmission methods for communicate within the network? (chapter 2)

In this Chapter 2, you will learn to:
Identify the primary network transmission methods.
Identify the main types of media access methods.
Identify the major network signaling methods.
Identify the elements of the data addressing and delivery process.
Identify common network connection mechanisms.
Identify techniques for ensuring reliable network data delivery.

The Transmission Methods

The primary transmission mechanisms that are implemented on the networks are:
Unicast transmission
Broadcast transmission
Multicast transmission



Unicast Transmission
Unicast transmission is a transmission method in which data is transferred from a specific source address to a specific destination address.


Broadcast Transmission
Broadcast transmission is a transmission method in which data goes from a source node to all other nodes on a network.


Multicast Transmission
Multicast transmission is a transmission method in which data is sent from a server to specific nodes that are defined as members of a multicast group.

Session 4 : The Windows System Management Tools (Last Session of Chapter 2)

Windows System Management Tools

Some of the important Windows system management tools are:
-The Computer Management Console
-The Registry

The Computer Management Console
Computer Management is the primary administrative tool you will use to manage and configure a Windows XP computer.



The Registry
The registry is the central configuration database where Windows stores and retrieves startup settings, hardware and software configuration information, and information for local user accounts.

What you have learn before,  let review it:
1-The commonly used operating system on a personal computer are Microsoft Windows, Unix, Linux, and Apple Macintosh Operating Systems.
2-The primary components of the Windows user interface are Windows desktop, taskbar, start menu, Windows explorer, My Computer, My Documents folder, control panel, command Prompt, and My Network Places. 
3-The primary tools and functions used in Windows file system management are directories and folders, file extensions, file attributes, file systems, and shared resources.
4-Some of the important Windows system management tools are computer management console and registry.

Session 3 : Windows File System Management (Continued....)

Windows File System Management

The primary tools and functions used in Windows file system management are:
-Directories and Folders
-File Extensions
-File Attributes
-File Systems
-Shared Resources

Windows supports several different file systems. They are:
+FAT / FAT32
   -Legacy file systems
   -Support dual-boot to DOS
   -FAT: floppy disks, very small drives
   -FAT32: enhanced for larger drives
   -No security, encryption, compression
+NTFS
   -Permissions
   -Encryption
   -Compression
   -Large files and drives
 +Media file systems
   -For other media



Permission
Permissions are security settings that control access to individual objects, such as files.

NTFS File Permissions

There are five standard NTFS permissions you can assign to files. They are:
~Read
~Write
~Read & Execute
~Modify
~Full Control

NTFS Folder Permissions
There are six standard NTFS permissions you can assign to files. They are:
~List Folder Contents
~Read
~Write
~Read & Execute
~Modify
~Full Control

Share Resource
A share is any network resource that is available to other computer users on the network. Typical shares include folders, printers, and drives.

Share folder permission
You can set three different levels of permissions on shared folders.

Session 3 : The Windows File System Management (Chapter 2)

Windows File System Management


The primary tools and functions used in Windows file system management are:
-Directories and Folders
-File Extensions
-File Attributes
-File Systems
-Shared Resources

Directories and Folder
Directory and folder are interchangeable terms for a component in a file system hierarchy that provides a container to organize files and other folders.



File Extensions
Standard file extensions following the names of files can indicate whether a particular file is a system, program, or data file.



File Attribute
There are several standard attributes you can set or clear on files and folders on Windows systems. They are:
~Archive
~Hidden
~Read-only
~System
~Index (Windows only)

Session 2 : Windows User Interface Components (Continued...)

Windows User Interface Components (Continued...)

The primary components of the Windows user interface are:
-Windows Desktop
-Taskbar
-Start Menu
-Windows Explorer
-My Computer
-My Documents Folder
-Control Panel
-Command Prompt
-My Network Places

My ComputerMy Computer is used to manage files and folders on a computer and on any storage devices attached to the computer. It has a single pane view of Windows explorer, which has an additional task pane.



My Documents FolderEach user on a Windows system has a personal folder named My Documents for storing the user’s individual files.



Control PanelThe Control Panel is a graphical interface that provides access to a number of utilities that you can use to configure the Windows operating system or the computer’s hardware.


Command PromptThe Command Prompt enables you to enter text-based commands or run command-line tools.



My Network PlacesMy Network Places is a view of My Computer that enables you to connect to other computers and to manage files and folders elsewhere on the network.
