A lot of companies have an intranet site. This is basically web pages that can be viewed by employees connected to the network in the office. The address does not use the standard .net or .com address. It will simply be http://companysite.
If you have an intranet site for your company, then when you talk to other workers, you don't need to say http:// everytime. You can simply say the name, for example, 'If you want to use a sick day, you can go to time report.' The other person listening should understand that you mean http://timereport.
