FILE ORGANIZATION

AND YOUR NETWORK


Networks

  • A network is a group of computers that can communicate or “talk” to each other through connections or links.

  • Computers are linked together by cabling or wireless satellite and a network interface card.

  • An advantage of a computer network is that users can share files and resources.

  • Networks are usually protected so that no unauthorized users can access those resources. The first line of defense on a network is a _____________ and a ________.


Two Types of Networks

  • LAN – Local Area Network

    • Computers are geographically close together

    • White Plains High computers are an example of a Local Area Network

  • WAN – Wide Area Network

    • Computers usually communicate using wireless connections and are not close together geographically

    • The Internet is the largest WAN.


How do networks work?

  • Each personal computer in a network is called a client.

  • A server is a high-speed computer that stores information to be shared and provides it to requesting clients.

  • Each computer in a network is connected in some way to the server.


It’s kind of like going to a fancy restaurant!

  • Your class members (or the clients) look at the menu and give your order to a waiter.

  • The waiter takes the order to the chef (the server) who prepares meals for everyone who has ordered.

  • The waiter then brings the meal back to you (the client).

Using your Computer Like a Filing Cabinet

  • Your school locker is an important place to you.

    • You can store your books and folders between classes.

    • You can store pens and pencils.

    • You can store assignments.

    • You can store a few pictures.

  • Neat students arrange everything in a logical order.


Neat Students Arrange Everything in Logical Order

Each class has its own notebook or folder

All assignments are arranged by date or project title.

Not-so-neat students simply throw one thing on top of another.

Good luck trying to find that assignment!

How do we organize?


Being organized

  • Computers don’t like disorganization.

  • Just as you use folders and notebooks for different classes, computers use drives, libraries, and files to store information.

  • Your computer’s hard drive is like your locker – it stores thousands of files.

    • Some of those files run your computer’s operating system.

    • Others run applications.

    • Still others contain data that you or someone else may have created.


What is a file?

  • Files are storage places for data.

  • Data can be in any form: numbers, text, images, and even voice and video.

  • You create files and name them using an application program.

  • You can tell what kind of a file it is by its icon and its letter extension (after the period). For example, dog.jpg is a picture; myfamily.docx is a Word 2010 document.


Other extensions

  • .xsl – Excel document

  • .ppt or .pptx—Powerpoint document

  • .txt—text file

  • .pdf—Adobe read only file

  • .bmp – bitmap (picture)

  • .png – ping (picture)

  • .gif –graphics interface (picture)


What is a library?

  • Another name for folder or directory

  • Like file folders in a filing cabinet

  • Folders are used as logical places to put related files.

  • Let’s create a folder for you now and learn how to organize your files.


What is a drive?

  • Storage places for data

  • A hard drive is the primary storage area on your computer. (C:\) It offers large storage capacity and fast retrieval.

  • Floppy Drives (A:\ and B:\) hold 1.44 mb of information and are removable.

  • Network Drives are assigned letters from F: to Z: and are treated the same as a hard drive. These are located on the server.

  • What letters are used for the CD Rom drive, the DVD player and flash drives?


File Hierarchy System

  • Files are placed in folders.

  • Folders are placed in Drives or other Folders.

  • The root directory is your starting place.

    • A:\ or B:\ - floppy

    • C:\ - hard drive inside computer

    • D:\ - DVD player

    • E:\ - flash drives

    • F:-Z:\ - Network drives located on the server

    • (On your computers, the letter J: is mapped as a jump drive instead of a network drive.)


Let’s Look At Our Typical Directory Structure


So, where do we save your files on the network?

  • To your folder on the server which is the ____ Drive. There you will find a folder created just for you named ____________.

  • Sometimes you will also save to a To Be Graded folder. You can find this folder on the server also by going to the ___ drive and then ___________ and ___________.


Review

  • What drive letter is our network drive?

  • Is White Plains High’s network a LAN or a WAN?

  • Is Calhoun County School’s network a LAN or a WAN?

  • What is the largest WAN?

  • What are two basic protections for a network?

  • What is the advantage of using a network?


Review

  • What is each personal computer in a network called?

  • What is the main computer called that talks to all of the computers on a network?

  • How can you tell by looking at a list of files what type of file it is?
