4.3 Packing-switching technology

the client is A and B while the server is C and D. The client is getting information from the server. IP address is where all the information is going and IP datagram is the data packet that conforms to the IP specifications. packets is what holds the information and concurrent data transmission is the problems that the packet-switching technology is taking care of and the TCP is what breaks the information into packets and the IP is what forwards packets from node to node also known as the routers. Packet-Switching Technology is how the information is broklen down into different packages and the distributed to the apropraite places.

4.2 Basic Network

server is the place that is going to provide the service to the client who is looking for the information. The transmission medium is when the client request information that has to come from the receiver. protocols are the rules that have to be set and followed. digitizing is when you convert information into bits,  wireless media comes from many devices such as blue tooth and GPS. cable median is made up of many wires that connect computers to  and bandwidth is transmission capacity.

4.4 ERD

Entity, attribute, attribute types, record, data types, database tables and relatiosnhips.
The enity is the tables. Attribute are the fields in the table and the information that is in that table are called the attribute types. A record makes up a row in the table of information. The database tables are each entity in the dadtabse so here it is the customer, invoice and product that will be in the database. And then the relatiosnhips that are here is the customer and the product come together as the invoice and they make up the keys for each and then the quantity the customer is getting.

4.1 IFS H/W infrastructure

In this imagine we are seeing how the computer transfer the data we enter into the language it understands. The input technologies that being inputed are the letters that spell out HELLO. The processing technologies is being used when the data that is being entered is being transfered over to the output. So by using the keyboard to type in Hello we are able to see it on the screen by the processing technologies. The output technologies are what is for the data to be usable. The machine language is the only thing that the computer can understand and that is on and off or 1 and 0. The bits are one number that is in the set of bytes. So it takes 8 buts to make a byte. And in the picture that is all the 1 and 0's that make up one letter. The ACSII binary code is also the 8 bits that are seen in the image. The ALU is where the computer does the math information, the CPU is the central processing unit and the control unit is the in CPU.

3.2 buiding a business case

  Customer Relationship Management -

• Faith:  We believe that this system will serve all customers the same and have an  influence on why the customers want to come to our Cinema and not the others. You just have to take it on faith.
• Fear:  If this system is not working the proper way then we will go out of business at the worse point becasue our competition will take us over. So we need to stay on top or we are system-free and fall to our competitors. 
• Fact:   As our analysis shows, implementing the functional area information system will improve the work quality of our employees by 45%. The facts show that with this system the training and work production is of a higher value quality. Errors will be significantly reduced as the stats have shown. They have dropped from 60% down to 12%. So in the long run, the systems will pay for itself within the next year.
