What Is a Computer Network ? • In the simplest terms, a computer network is a collection of computers that communicate with each other to allow the sharing of information and equipment. • The information might be something as simple as a staff memo or something as complex as a student record database. Shared equipment might include anything from a disk drive and a printer to an entire building of computers. • The advantage of a network is that a student could just as easily share his work with another student down the hall in another class as with a student halfway around the world.
The Internet Is the Largest Network in Existence.
In a Peer-to-Peer Network, Computers simply connect with each other in a workgroup to share files, printers, and Internet access. This is most commonly found in home configurations, and is only practical for workgroups of a dozen or less computers. If you have a cable modem or DSL line at home and several computers can use the Internet at the same time, chances are that you are set up as a peer-to-peer network.
Buffalo Seminary uses a Client/Server network. <ul><li>In a client/server network , there are usually a large number of computers (called workstations or clients) which connect to a main computer (called the fileserver or domain controller). </li></ul><ul><li>Most of the computers in the building are clients or workstations. </li></ul><ul><li>Our file server is a computer in the closet near the study hall. </li></ul>
Where to find stuff <ul><li>Open My Documents… You’ll find your files. When you create a document and save it – this is where it will be saved automatically. </li></ul><ul><li>Now, open My Computer… You’ll find all the folders on the server that you have access to. </li></ul>
Shared Files on the Network <ul><li>classes on ‘bufsem-fs2’ </li></ul><ul><ul><li>Only teachers can make changes, but students can copy files. </li></ul></ul><ul><li>students on ‘bufsem-fs2’ </li></ul><ul><ul><li>Teachers and students both have access to files and may change them. Only save something to this folder if you will need to share it with another student or a teacher. </li></ul></ul><ul><li>“ your name” on bufsem-fs2 </li></ul><ul><ul><li>This is your “My Documents” folder </li></ul></ul>
All of these files are really saved on the server, so that you can work on them from any computer in the school. <ul><li>My documents </li></ul><ul><li>Students on Bufsem-fs2 </li></ul><ul><li>Classes on Bufsem-fs2 </li></ul>Note: each computer has a name so that it can be a member of the network domain (just like you have a username to be a member) The name of the network server is Bufsem-fs2
Shared Printers <ul><li>All students are setup to print to 2 of the network printers </li></ul><ul><ul><li>Computer lab laser </li></ul></ul><ul><ul><li>Library Laser </li></ul></ul>Start search for printers If you need to print in color, please see me to access the color printer in the computer lab.
FILE STRUCTURE <ul><li>Just as it is important to be able to locate a paper document in the correct folder or notebook in your schoolbag, it is necessary to be aware of the exact location of electronic files. Just like a filing cabinet, files in your computer can be organized into folders to make them easier to manage. Folders can contain documents or other folders. </li></ul>
Folders and Files <ul><li>A file is usually stored in a Folder. A folder on your computer works the same way as a folder in a filing cabinet. Folders act as containers for files, and are used to separate and organize files into groups. Folders can contain any type of file, and even other folders. You can create your own folders. </li></ul>When you save your work, it becomes a file . A file is a collection of data stored under a specified name on a disk. (ex. Science Lab #1). A Word document is a file. An excel workbook is a file. A database which can consist of many tables and forms is a file. There are many different types of files. Each type has its own label or extension to identify it’s type to your computer and to you.
File Types <ul><li>File Names </li></ul><ul><li>Each file in your computer is stored with a distinct file name . These names are made up of two parts: a description and an extension. The description usually identifies the contents of the file. If you create the file, you decide on this part of the name) The extension identifies the type of file. </li></ul><ul><li>The full file name consists of the description and extension, separated by a dot (.). </li></ul><ul><li>Sometimes, the extension may not appear, but it is always part of the official file name. </li></ul>Each of the eight sample files has a different icon (the small image next to the file name). The different icons can also help you to identify the file type. For example, every Word document will have the same icon as the one shown for Technology Skills.doc, and every text file will have an icon like the one shown for notes.txt. PowerPoint file Excel file Acrobat reader file Access database file Word file Image file Internet Explorer html file Text file extensions icons
Drives A Drive is a place where folders and files are stored. Compare a drive to a drawer in a file cabinet. Each (drive) drawer is labeled and can contain folders and files. The computer you are working on has several drives. The computer’s hard drive is called the C: drive. It is called C because early computers always had 2 floppy disk drives A: and B: If your computer has a floppy drive (many newer machines do not), that drive will almost always be the A: drive. If you have other drives on your computer, like a CD or DVD drive, they may be labeled D: or E: or F:. Etc. Network Drives On a network, we can use drives that actually reside on our server. ( Our server is a special computer that lives in the closet near the study hall.) The server can have many drives that domain members (people who have user names and passwords) can use. Many of the drives on the server are restricted and can only be used by faculty and staff. Local Drives
Our Network Drives There are three network drives that students have access to. These are labeled with names, and letters; Students on Bufsem-fs2 (L:) This drive is for you to store files and folders that you need to share with other students or teachers. You can add folders and label them so that you can both find them. Your teachers may ask you to create new folders for a class or class project. Classes on Bufsem-fs2 (K:) This drive is for teachers to use to post information that they may want you to use for your class work. Students can not store documents on this drive, but can copy the teachers documents and store them either in the “Students” drive or in their own “My Documents” folder Your Name on Bufsem-fs2 (Z:) This drive is your “My Documents” folder. This directory is your own private storage area on the network.
Saving a Document to a Network Drive <ul><li>After you have created a document that you need to share with another member of the Domain (a teacher or student), you must save it to the Network drive: Students on BufSem-fs2. </li></ul>RE DO THIS IMAGE Under the pull down file menu choose “SAVE AS”. A dialog box will open so that you can choose the correct place to save your document. 1. 2. 3.

Deleting files and folders <ul><li>To delete files or folders: </li></ul><ul><ul><ul><li>Select the files or folders that you want to delete. For instructions on how to select multiple files and folders, see "Selecting files ” </li></ul></ul></ul><ul><ul><ul><li>Right-click, then select Delete from the pop-up menu. Windows moves the files and folders to the Recycle Bin. </li></ul></ul></ul><ul><ul><li>When you throw away paper files and folders, you take them out of your file cabinet and put them in a trash can. Eventually a trash collector empties the can and takes the trash away. </li></ul></ul><ul><ul><li>In Windows, you throw away files and folders by first moving them to Windows trash can, the Recycle Bin , where they remain until you decide to empty the bin. </li></ul></ul><ul><ul><li>The Recycle Bin not only serves as a receptacle for files that you want to delete, it also serves as temporary container for those unwanted files. You can recover any file in the Recycle Bin as long as the bin has not been emptied. </li></ul></ul>
Selecting Multiple Files <ul><li>If you need to move, copy or delete more than one file at a time, here is a time-saving tip </li></ul><ul><li>If the files are adjacent </li></ul><ul><ul><li>hold down the “shift” key </li></ul></ul><ul><ul><li>Click on the first file in the group </li></ul></ul><ul><ul><li>Click on the last file in the group </li></ul></ul><ul><ul><li>Release the shift key </li></ul></ul><ul><ul><li>Now you can complete the action </li></ul></ul><ul><li>If the files are scattered </li></ul><ul><ul><li>Hold down the “CTRL” key </li></ul></ul><ul><ul><li>Click on each file that you want </li></ul></ul><ul><ul><li>Now you can complete the action </li></ul></ul>BACK

Get Organized ! <ul><li>Every time you finish typing a paper or homework assignment, you save it on the computer so that you can work on it again later, or in case your dog eats it and you have to print it out again. If your doggy does have a snack and you have to reprint your paper, you need to be able to find it again. If you just hit “save”, chances are your paper is safely stored in your “My Documents” folder. What if you have dozens of other papers stored in that folder too? You may have History papers and French papers and Science labs all tossed into your “My Documents” folder (which may also be how your bedroom looks)! </li></ul>You need to ORGANIZE! This lesson will explain all about files and folders and the places you can store your work so that you can find it again easily.
My Documents <ul><li>On your desktop or in the Start menu you will find this icon. Double click on it to open the “My Documents” folder. This where you should save and store your work. You can create, delete, copy, and rename files and folders to keep your documents sorted by topics that make sense to you. The main objective is to make it easier for you to find what you are looking for. </li></ul>Double-clicking on any file will open it.
Let’s clean this up ! <ul><li>This folder contains all of the schoolwork that you have saved so far this year. There are documents from all your classes lumped together. Yikes!! </li></ul><ul><li>OK – let’s get organized! What you need is a separate folder for each class! </li></ul><ul><li>Let’s make the new folders first, then we can move the documents into the correct folders. </li></ul>
Creating a new folder Place your mouse in an empty space and right click, choose > New > Folder. Type a name for your folder and press Enter. A new folder appears with the temporary name, New Folder. 1. 2.
