23
Q

Describes the hardware/software components in detail to aid those responsible for purchasing those products.

A

Hardware and software specification

24
Q

Architecture Design: Software systems can be divided into four basic functions called

A
  1. Data Storage
  2. Data Access Logic
  3. Application Logic
  4. Presentation Logic
25
Q

Architecture Design: the processing required to access stored data.

A

Data Access Logi

26
Q

Architecture Design: the logic documented in the DFDs, use cases, and functional requirements.

A

Application Logic

27
Q

Architecture Design: the display of information to the user and the acceptance of the user’s commands.

A

Presentation Logic

28
Q

Architecture Design: What are the three primary hardware components?

A
  1. Client Computers
  2. Server
  3. Network
29
Q

Architecture Design: Generally, which part of hardware process which four of the software functions?

A
  1. Client - Presentation Logic
  2. Server - Data Storage and Data Access Logic
  3. Presentation logic may vary depending on the configuration
30
Q

Architecture Design: Client-Server Architecture Can support different types of clients and servers through?

A

Middleware

31
Q

Architecture Design: If a server fails, all application in the architecture are affected (T or F)

A

False. Only the applications residing in that server are affected.

32
Q

Architecture Design: A type of two tiered architecture where the application and presentation logic reside in the Client

A

Thick Client

33
Q

Architecture Design: A type of two tiered architecture where most of the application logic reside in the server

A

Thin Client

34
Q

Architecture Design: Adds “specialized” servers – one for application logic; one for data base task (basically adding an application server)

A

Three tiered client-server architecture

35
Q

Architecture Design: The difference between a three and N tiered architecture is?

A
  1. A specialized server for web related business logic
36
Q

Architecture Design: More tiers in the architecture allow for better server loads (T or F)

A

True

37
Q

Architecture Design: More tiers in the architecture places a lesser load on the network (T or F)

A

False. Higher load

38
Q

Architecture Design: Almost all functions are run by the server

A

Server-based architecture or zero client computing

39
Q

Architecture Design - Mobile Application Architecture: involves processing on the mobile device using its resources
