Short Answer
1. A compiler is a computer program that transforms source code written in programming language into another computer language.
An interpreter is a computer program that executes performs, instructions written in a programming language.
The advantage of an interpreter : Interpreters are useful for program development when execution speed is not important. As the interpreter is in command of the execution process debugging features can be build in.
The disadvantage of an interpreter : Interpreters normally translate and execute programs line by line, converting each program statement into a sequence of machine code instructions and executing these instructions without retaining the translated version.
2. Major benefit of OOP :
- software objects model real world objects, so the complexity is reduced and the program structure is very clear
- each object forms a separate entity whose internal workings are decoupled from
other parts of the system
RAD (rapid application development) is a method of developing software, in which a programmer writes and implements a program in segments instead of waiting until the entire program is completed.
3. A code editor, a compiler, a debugger, and a graphical user interface (GUI) builder is included in an integrated development environment.
The programming languages in the Visual Studio suite is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually.
4. XML is used in many aspects of web development, often to simplify data storage and sharing.
Two applications of XML :
- RSS 2.0 : stands for really simple syndication
- ATOM : specificator that content aggregators use to distribute content to subscribers.
5. In documenting the solution, the programmer performs two activities :
1. review the program code
2. review all the documentation
Proper documentation greatly reduces the amount of time a new programmer spends learning about existing programs.

Short Answer
1. Systems development is the process of defining, designing, testing, and implementing a new software application or program.
Investigation : During this stage, business opportunities and problems are identified, and information technology solutions are discussed.
System Analysis : This step involves breaking down the system in different pieces to analyze the situation, analyzing project goals, breaking down what needs to be created and attempting to engage users so that definite requirements can be defined.
Design : In systems design the design functions and operations are described in detail, including screen layouts, business rules, process diagrams and other documentation.
Testing : The code is tested at various levels in software testing. Unit, system and user acceptance testings are often performed.
Operations and Maintenance : Maintaining the system is an important aspect of SDLC. As key personnel change positions in the organization, new changes will be implemented, which will require system.
2. Operational feasibility reviews the willingness of the organization to support the proposed system. This is probably the most difficult of the feasibilities to gauge. It measures how well the information system will work.
Schedule feasibility a rough estimate of the project schedule is required to determine if it would be feasible to complete the systems project within a required timeframe. Measures whether the established deadlinea for the project are reasonable.
Technical feasibility considers the technical requirements of the proposed project. Measures whether the organization has or can obtain the hardware, software, and people needed to deliver.
Economic feasibility will review the expected costs to see if they are in-line with the projected budget or if the project has an acceptable return on investment. measures whether the lifetime benefits of the proposed information system will be greater than its lifetime costs.
Six techniques to gather data and information : review documentation, observe, survey, interview, conduct join-app design sessions, and research.
3. Unified Modeling Language combines techniques from data modeling (entity relationship diagrams), business modeling (work flows), object modeling, and component modeling. It can be used with all processes, throughout the software development life cycle, and across different implementation technologies.
A class diagram in the Unified Modeling Language is a type of static structure diagram that describes the structure of a system by showing the system's classes.
Meanwhile, a case diagram is used at a higher level than within software engineering, often representing missions or stakeholder goals.
4. Perform maintenance activities : fix the errors to improve a system's operation.
Monitor system performance : the system must investigate solutions to make the informations more reliable.
Assess system security : to ensure that necessary security controls are integrated into the design and implementation of a project.
5. A computer security plan is to summarize in writting all of the safeguards.
_ identify all information assets of an organization
_ identify al security risks that may cause the lost of information asset
_ identify the safeguards that exist to detect, prevent, and recover from a loss
