There are three primary types of program translator that are used to translate source program code
into object program code: Interpreters, Compilers, and Just-in Time Compliers.
1.3 1 Questions Program Translators - Compilers versus Interpreters
17. What is the function of a Program Language Translator?
Enter your Answer
è
They are used to translate source program code into object program
code.
18. What is Program Source Code?
Enter your Answer
è
Source code is the list of human-readable instructions that a
programmer writes that meets defined program specifications once the program is
executed.
P a g e
7 | 47
ASSIGNMENT 4 THEORY SPRING 2022
19. What is Object Code?
Enter your Answer
è
The object code is the translated code that is the output of a
compiler.
20. Summarize the process that a Program Compiler will use to translate Source Program Code into
Object Code.
Enter your Answer
è
It translates the source code into a file to which the file is then run by the
operating system.
21. Summarize the process that a Program Interpreter will use to translate Source Program Code into
Object Code.
Enter your Answer
è
An interpreter does not produce object code.
22. Using the following table list the advantages and disadvantages of using Compilers as a
translator.
Advantages
Disadvantages
fast
Hard to find errors
efficient
Continues even if there is an error
Reliable translation
Requires effort to be reliable
23. List the advantages and disadvantages of using Interpreters as a translator using the following
table.
Advantages
Disadvantages
Help test code quicker
slow
Debugging is easier
Translates multiple times
Stops when there is an error
Translates line by line
Many IDEs like Microsoft Visual Studio, Eclipse, Net Beans, XCode, or IBM's iDz will provide
both Interpreter and Compiler translators.
Interpreters are very useful during the initial coding
and testing phases.
Some IDEs will highlight syntax or typing errors as they type the source
code. But, almost all IDEs will use an Interpreter to execute code (RUN) one line at a time
until they encounter an error. At least the developer gets some type of execution. Many IDEs
will use the interpreter to "step through" the execution of the program one-line-at-a-time a
program to help the programmer debug the error.
However, the limitations of a program interpreter to execute the program are too many, that
the program source code will be compiled into a, executable file or load module. When the
programmer is finished with application development and testing, the BUILD tool will use the
compiler to translate source code into object code and will combine all object code into a,
assembly, package or load module to be deployed and executed.

Students or new developers may be more familiar with graphical user interfaces than text-based CLI
or menu interfaces, such as Visual Studio and Eclipse-based plugin IDEs
Integrated Development
Environment (IDE) clients and software for building applications that combines common
developer tools into a single graphical user interface (GUI).
IDEs are often called thick clients.
IDE Source Code editors
assist in writing software code faster and with less experience.
Highlights syntax with visual cues, e.g., highlights program structure and distinguishes
statements and clauses from data.
Provides language specific auto-completion, e.g., predicts program syntax or data names after
a few keystrokes.
Checks for bugs and syntax errors or autocorrects program code is being written.
IDE Local or Server Build and Testing Automation tools
will simplify the process or compiling
source code into executable code, package binary executable code, and runs automated tests.
Testing focuses on finding bugs and errors and are used to ensure that the program is correct and
meets specification standards.
IDE Debugger Tools
are designed to assist programmers to troubleshoot the cause of run-time,
logic, or program specification errors after program bug has been found.
There are hundreds of IDE Clients and Tools available to support a variety of server and mobile
operating systems, program languages, web page (HTML) design, middleware integration and data
storage, and application security testing.

3.4 Questions - FORTRAN and COBOL
"Fortran (previously FORTRAN) is a general-purpose, procedural, imperative programming language that is
especially suited to numeric computation and scientific computing. Originally developed by IBM at their campus
in south San Jose, California in the 1950s for scientific and engineering applications, Fortran came to dominate
this area of programming early on and has been in continual use for over half a century in computationally
intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics,
computational physics and computational chemistry. It is one of the most popular languages in the area of high-
performance computing and is the language used for programs that benchmark and rank the world's fastest
supercomputers."

4.0 Introduction to COBOL Application Development
4.1 Overview of COBOL
Using Programming Languages on z/OS - Chapter 9.
Introduction to the New Mainframe: Z/OS Basics
Compiling and Link-editing a Program on z/OS - Chapter 10.
Introduction to the New Mainframe: Z/OS
Basics
COBOL History
http://www.mainframegurukul.com/tutorials/programming/cobol/cobol-history.html
COBOL Program Structure
http://www.mainframegurukul.com/tutorials/programming/cobol/cobol-program-
structure.html
COBOL – Overview - http://www.tutorialspoint.com/cobol/cobol_overview.htm
The COBOL (Common Business Oriented Language) was introduced by IBM in 1959 as third
generation programming language.
COBOL has changed and improved several times. While some
will state that ANSI COBOL-85 is the current version of COBOL this is not exactly accurate. COBOL-
85 is the minimum requirements for COBOL and the actual syntax and rules vary by the company who
made the COBOL compiler.
For example, the current COBOL compiler being used on IBM mainframes is called Enterprise
COBOL for z/OS version 5, which replaced VS COBOL II. However, the actual version of IBM COBOL
will depend on the actual operating system, e.g., MVS, AIX, etc. as well as COBOL versions on Linux
and Windows Platforms. Unlike Java and .NET, COBOL is NOT platform independent.
The latest
IBM COBOL compiler will also help integrate business logic written in COBOL with web and mobile
user interfaces by providing interoperability with XML and Java.
COBOL was designed to support business applications that need to 1) efficiently interface with data
files, data sets, and databases, 2) minimize memory usage (small foot print), and 3) efficiently use
processor resources. On average, a compiled COBOL application uses, on the average, 15% less
memory and 40% less processing time compared to a Java module with the same business
requirements. However, COBOL is not platform independent, is not designed to support all modern
user interfaces, has very limited advanced mathematics functions and ability to communicate outside
its address space.
When COBOL cannot perform an application requirement on the mainframe, this limitation may be
overcome by simply writing an Assembly Language program. IBM COBOL and IBM Assembler were
made to work together, taking into consideration the advantages of each language.
Java was designed to be a platform independent, object-oriented programming language, designed to
promote re-usability of source or byte-code, to easily add new features to the program language.
Those advantages come with a substantial processing overhead.
C was designed as a high-level
programming language to be as powerful and flexible as the assembler programming language. But
unlike COBOL, a powerful and flexible programming language creates security concerns.

4.2 Compile, Link and Execute
The traditional steps for developing a computer program after determining the program requirements
(what do you want the program to do?) are: 1 Write the computer source code using some type of
editor, 2) Translating the code into object code using either Interpreters, Compilers, and Just-in Time
Compliers, 3) Linking the object
to a load library which contains pre-written routines applicable to
your operating system, 4) store an executable program file, and then load and
execute the
executable file by either entering the file name, clicking on an icon or short-cut, etc. The following
diagram provides and overall view of the process.

6.0 Important Technology Trends
There are several technology trends that are dominating the focus of new projects in Business and
Government. These new technology trends will affect the role and skills required for system analysts,
project managers, and software engineers. Several of these new technology trends are discussed in
the following section. You will be required to demonstrate your basic knowledge and apply these
technologies to project example using your personal examples with your organization or to some
organization that you have researched.
6.1 Questions - BYOD
Mobile interface in diverse contexts and environments as opposed to focusing on devices alone or
consumer roles. For example, the trend to introduce BYOB/ BYOT in the workplace or public space
will continue to raise significant management challenges for IT organizations as they lose control of
user endpoint devices. It will also require increased attention to user experience design.

3. Using your personal example or an example from your current or previous employer, specifically
describe a project's requirements, potential benefits (pros) and costs (cons) for
a BYOD project.
Answer =>
The project required me to use my own phone to document current inventory and the pros were that I
know where and how to document the data but the cons were that I got distracted with other apps on
my phone.
6.2 Web Services, Service Oriented Architectures (SOA), and Restful
Batch Processing has no user interface. OLTP system interface with a commercial, consumer or other
user. Web services was constructed to have one computer program or electronic device to use the
services of another computer program or electronic device, no matter what the programming
language, operating system, or physical location of the computer program. The flexibility to design
programs to communicate with each other is call interoperability.
Many web services are often started by a user request. For example, the travel site named Kayak,
permits a user to input flight information which queries the databases of various airline reservations
using web services. This is only one example, called a metasearch engine, of the many which use
web service applications. This process can also query hotel reservation systems or car rental
systems.
Web services can be implemented by two different programming approaches: traditional SOAP-based
web services and Restful-based web services. While both technologies have valued those systems
that rely on web-based user transaction are be transitioned to the easier-to-use and more powerful
Restful-based technologies.
It is important to notice that 70% of new application programming hires require knowledge or SOAP.

The Internet is expanding beyond PCs and mobile devices into enterprise assets such as field
equipment, and consumer items such as cars and televisions. The problem is that most enterprises
and technology vendors have yet to explore the possibilities of an expanded Internet and are not
operationally or organizationally ready.
Imagine digitizing the most important products, services and assets. The combination of data streams
and services created by digitizing everything creates four basic usage models – manage; monetize;
operate; extend. These four basic models can be applied to any of the four "Internets” (people, things,
information and places).
Enterprises should not limit themselves to thinking that only the Internet of
Things (i.e., assets and machines) has the potential to leverage these four models. Enterprises from
all industries (heavy, mixed, and weightless) can leverage these four models
A sensor is not a machine. It doesn’t do anything in the same sense that a machine does. It
measures, it evaluates; in short, it gathers data. The Internet of Things really comes together with the
connection of sensors and machines. That is to say, the real value that the Internet of Things creates
is at the intersection of gathering data and leveraging it. All the information gathered by all the sensors
in the world isn’t worth very much if there isn’t an infrastructure in place to analyze it in real time.
1. Provide a detailed definition of the Internet of Things (IoT).
Answer =>
The Internet of things (IoT) describes physical objects (or groups of such objects) with sensors,
processing ability, software, and other technologies that connect and exchange data with other
devices and systems over the Internet or other communications networks.
2. Provide a detailed example of Internet of Things (IoT) that will affect your home.
Answer =>
It will allow home appliances to connect to and use the internet to perform tasks that they are usually
not able to do such as a fridge being used to order stuff off of amazon (Samsung smart fridge).
3. Provide a detailed example of Internet of Things (IoT) that will affect your workplace.
Answer =>
Devices would be able to track and document a worker's tasks and effort which can be seen in
inactivity sensors that log the employee out of their system or send status reports to supervisors.
4. Provide a detailed example of Internet of Things (IoT) that will affect public utilities, e.g., the elective
grid, your cable T.V., etc.
Answer =>
Public utilities will be able to cater towards you based on your internet activity such as targeted
advertisements.
5. List three or more advantages of IoT technologies.
Answer =>
Makes difficult tasks easier
Makes tasks more convenient
Can cater towards you

Software-defined anything (SDx) is a collective term that encapsulates the growing market momentum
for improved standards for infrastructure programmability and data center interoperability driven by
automation inherent to cloud computing, DevOps and fast infrastructure provisioning. As a collective,
SDx also incorporates various initiatives like OpenStack, OpenFlow, the Open Compute Project and
Open Rack, which share similar visions. As individual SDx technology silos evolve and consortiums
arise, look for emerging standards and bridging capabilities to benefit portfolios, but challenge
individual technology suppliers to demonstrate their commitment to true interoperability standards
within their specific domains.
While openness will always be a claimed vendor objective, different interpretations of SDx definitions
may be anything but open. Vendors of SDN (network), SDDC (data center), SDS (storage), and SDI
(infrastructure) technologies are all trying to maintain leadership in their respective domains, while
deploying SDx initiatives to aid market adjacency plays. So, vendors who dominate a sector of the
infrastructure may only reluctantly want to abide by standards that have the potential to lower margins
and open broader competitive opportunities, even when the consumer will benefit by simplicity, cost
reduction and consolidation efficiency.

6.5 Risk-Based Security, Self-Protection and Context Rich Systems
Organizations will increasingly recognize that it is not possible to provide a 100 percent secured
environment. Once organizations acknowledge that, they can begin to apply more-sophisticated risk
assessment and mitigation tools. On the technical side, recognition that perimeter defense, e.g.,
firewalls, IDSs, etc., is inadequate and applications need to take a more active role in security gives
rise to a new multifaceted approach. Security-aware application design, dynamic and static
application security testing, and runtime application self-protection combined with active context-
aware and adaptive access controls are all needed in today's dangerous digital world. This will lead to
new models of building security directly into applications. Perimeters and firewalls are no longer
enough; every app needs to be self-aware and self-protecting.
Security-aware application design, dynamic and static application security testing, and runtime
application self-protection combined with active context-aware and adaptive access controls are all
needed in today’s dangerous digital world. This will lead to new models of building security directly
into applications. Perimeters and firewalls are no longer enough; every app needs to be self-aware
and self-protecting.
Context-Rich Systems
Ubiquitous embedded intelligence combined with pervasive analytics will drive the development of
systems that are alert to their surroundings and able to respond appropriately. Context-aware security
is an early application of this new capability, but others will emerge. By understanding the context of a
user request, applications can not only adjust their security response but also adjust how information
is delivered to the user, greatly simplifying an increasingly complex computing world.
In today’s hacker filled world, context aware security solutions are extremely important as
organizations seek to encourage collaboration with employees and non-employees alike, across
disparate networks, systems and devices. Solutions that provide sophisticated identity and access
management capabilities by looking at users and their context, to dynamically provide secure access
to systems, applications and content are necessary to protect your business and most important
asset- it’s data.
This approach combines both classification and document level encryption to effectively secure and
control content. Using this unique combination of content, context and identify aware security allows
you to monitor for all types of content uses across your organization. It offers the most comprehensive
approach for secure collaboration.
