How to share file and printer in a computer network?

Setting up a printer on your network involves two steps. 

The first step is getting the printer connected to the network, and there are three ways you can do that:

• Connect the printer to the network directly. This is the easiest way to set up a network printer.  It doesn’t require that another PC be turned on to print (like the below methods do), and you don’t have to go through the hassle of setting up sharing. And, since most printers made within the last few years have networking built in, there’s a good chance your printer supports this option.
• Connect the printer to one of your PCs and share it with the network over Homegroup. If connecting a printer directly to the network isn’t an option, you can connect it to a PC on the network and share it with Windows Homegroup. It’s easy to set up, and is optimal for networks that are made up of mostly Windows computers. This method, however, requires that the computer its connected to be up and running in order for you to use the printer.
• Connect the printer to one of your PCs and share it without Homegroup. This is ideal if your network has other computers running different operating systems, if you want more control over file and printer sharing, or if Homegroup just isn’t working very well. Like the Homegroup method, this requires that the computer its connected to be up and running in order for you to use the printer.

HOW TO FILE SHARE BETWEEN COMPUTERS

HOW TO SHARE FILES

1Click the Start menu and choose Network.

You may see icons for all your connected PCs, as shown here. To find out how to file share between computers, you first need to connect to a PC; double-click its name. Chances are, you’ll be able to see files on your Windows XP PCs, but not any other Vista PCs. To see files on Vista PCs, move to Step 2.

2Click the Network and Sharing Center button.

The Network and Sharing Center button, seen along the top of the previous figure, fetches the Network and Sharing Center, shown here.

3How to file share between computers? Turn on Public Folder Sharing and click Apply.

Click the word Off in the Public Folder Sharing area, and the settings menu drops down, as shown here. To share your files, choose Turn On Sharing So Anyone with Network Access Can Open, Change, and Create Files.

4Turn off Password Protected Sharing and click Apply.

There’s one last hurdle. When somebody on the network tries to see inside a Vista PC’s Public folder, they must enter a name and password from an account on that other PC; their own name and password won’t do.

Although that makes for a very secure PC, it’s overkill in a family environment. To remove that layer of security, click the word On in the Public Folder Sharing area, as shown here. When the menu drops down, choose Turn Off Password Protected Sharing.

5Place files and folders you want to share with others into your PC’s Public folder.

And you’re done!

What is disk partitioning?

Disk partitioning is the creation of one or more regions on a hard disk or other secondary storage, so that an operating system can manage information in each region separately. 

Partitioning is typically the first step of preparing a newly manifactured disk, before any files or directories have been created. 

Remember : 

1 KB = thousand bytes

1 MB = million bytes

1 GB = billion bytes

1 TB = trillion bytes

1 KB = 1024 bytes 

1 MB = 1024 KB

1 GB = 1024 MB

1 TB = 1024 GB 

Original size/capacity = 40955

P1 = 50 % = 40955 X .50 = 20498

P2 = 50% = 40955 X .50 = 20498
