Blog Entry 5.3

Explain how your company would use an intranet to offer services to its employees.  Use the terms extranet, VPN, firewall, client, server, and internet in your 3-5 sentence discussion.

         My company (Pharmacy) would use intranet to offer services to our employees by providing them with quality e-training, easily streamlined information and the sharing of files.  Like extranet, intranet also consists of a private network.  Protected by the Virtual Private Network or VPN and firewalls our intranet is highly protected.  All of the clients that we will be working with wil have to travel through all of our security before reaching our server. 

Blog Entry 4.4

Explain your ERD using the following terms : entity, attributes, attribute types, record, data types, database tables, and relationships

     My Entity Relationship Diagram (ERD) shown above shows how the Pharmacy is broken up.  Each entity has its own set of attributes.  Attributes are individual pieces of information about an entity.  The type of attribute in the database is known as the data type.  A collection of attributes in an ERD are known as records.  All of these are located on a database table.  This is where the collection of related data is stored in order to facilitate searches. 

Blog Entry 5.2

• ¨Explain how your company would use an extranet to do business with another business.  Use the terms extranet, VPN, firewall, client, server, and internet in your 3-5 sentence discussion.
  
   
   
             The diagram above is an extranet diagram.  Extranet enables 2 or more firms to use the internet to do business through use of VPN and firewall technologies.  VPN or Virtual Private Network is used to ensure transmission of proprietary information.  The Firewall or the gatekeeper is used to authenticate users and provide security.  In extranet the client must travel through the firewall and VPN to get to the server.  My company (the Pharmacy) can benefit from using the extranet because there is no special training needed and it reduces the number of misunderstandings.

Blog Entry 4.2 - A Basic Network

—Got to gliffy.com and draw a basic network.  Upload your diagram to your blog entry.

—Write a 5-10 sentence paragraph explaining your diagram using the following terms : server, client, transmission medium, protocols, digitizing, wireless media, cable media and bandwidth.

      The more advanced microprocessor on the left which stores more memory than the others is called the server.  The workstations or PC's on the right are called clients.  They are the ones that request services.  To send data between the server and clients you need what is called transmission data.  Transmission data is the physical pathway for sending data.  There are two ways you can do this through either wired or wireless connections.  Protocols are the rules used to dictate the communication between them.  The amount of capacity allowed between the server and client is bandwidth.
