The document discusses application program interfaces (APIs) and how they allow programmers to use operating system and hardware functions without needing to know all the technical details. It provides an example of a programmer using an API call to create a file, with the operating system then handling the disk queries, file system entry creation, and hardware-specific operations behind the scenes. APIs have become important in the software industry as controlling a popular API can influence what programs are written and provide revenue opportunities.
This presentation covers the understanding of system calls for various resource management and covers system calls for file management in details. The understanding of using system calls helps to start with working with device driver programming on Unix/Linux OS.

Google File System was innovatively created by Google engineers and it is ready for production in record time. The success of Google is to attributed the efficient search algorithm, and also to the underlying commodity hardware. As Google run number of application then Google’s goal became to build a vast storage network out of inexpensive commodity hardware. So Google create its own file system, named as Google File System that is GFS. Google File system is one of the largest file system in operation. Generally Google File System is a scalable distributed file system of large distributed data intensive apps. In the design phase of Google file system, in which the given stress includes component failures , files are huge and files are mutated by appending data. The entire file system is organized hierarchically in directories and identified by pathnames. The architecture comprises of multiple chunk servers, multiple clients and a single master. Files are divided into chunks, and that is the key design parameter. Google File System also uses leases and mutation order in their design to achieve atomicity and consistency. As of there fault tolerance, Google file system is highly available, replicas of chunk servers and master exists.

Introduction to Computing lecture presentation to analyze the number systems handled by digital computing devices to process data, convert decimal to binary, solve Binary Arithmetic, and extend understanding of other number systems (Octal and Hexadecimal).
Digital computer deals with numbers; it is essential to know what kind of numbers can be handled most easily when using these machines. We accustomed to work primarily with the decimal number system for numerical calculations, but there is some number of systems that are far better suited to the capabilities of digital computers. And there is a number system used to represents numerical data when using the computer.
This lecture presentation recognizes the difference between IS and IT, reflection on its role in different disciplines and anticipate careers in IT or IS fields.
The presentation is about the career path in the field of Data Science. Data Science is a multi-disciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from structured and unstructured data.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Lesson 10 Application Program Interface
1. MODULE IN ITE229 - OPERATING SYSTEMS 20
Prepared by: For-Ian V. Sandoval
LESSON 10
APPLICATION PROGRAM INTERFACE (API)
Just as drivers provide a way for applications to make use of
hardware subsystems without having to know every detail of the
hardware's operation, application program interfaces (APIs) let
application programmers use functions of the computer and operating
system without having to directly keep track of all the details in the CPU's
operation. Let's look at the example of creating a hard disk file for holding
data to see why this can be important.
A programmer writing an application to record data from a
scientific instrument might want to allow the scientist to specify the name
of the file created. The operating system might provide an API function
named MakeFile for creating files. When writing the program, the
programmer would insert a line that looks like this:
MakeFile [1, %Name, 2]
In this example, the instruction tells the operating system to create a
file that will allow random access to its data (signified by the 1 -- the other
option might be 0 for a serial file), will have a name typed in by the user
(%Name) and will be a size that varies depending on how much data is
stored in the file (signified by the 2 -- other options might be zero for a
fixed size, and 1 for a file that grows as data is added but does not shrink
when data is removed). Now, let's look at what the operating system does
to turn the instruction into action.
The operating system sends a query to the disk drive to get the
location of the first available free storage location.
With that information, the operating system creates an entry in the
file system showing the beginning and ending locations of the file, the
name of the file, the file type, whether the file has been archived, which
users have permission to look at or modify the file, and the date and time
of the file's creation.
The operating system writes information at the beginning of the file
that identifies the file, sets up the type of access possible and includes
other information that ties the file to the application. In all of this
information, the queries to the disk drive and addresses of the beginning

and ending point of the file are in formats heavily dependent on the
manufacturer and model of the disk drive.
Because the programmer has written the program to use the API for
disk storage, the programmer doesn't have to keep up with the instruction
codes, data types and response codes for every possible hard disk and
tape drive. The operating system, connected to drivers for the various
hardware subsystems, deals with the changing details of the hardware.
The programmer must simply write code for the API and trust the
operating system to do the rest.
APIs have become one of the most hotly contested areas of the
computer industry in recent years. Companies realize that programmers
using their API will ultimately translate this into the ability to control and
profit from a particular part of the industry. This is one of the reasons that
so many companies have been willing to provide applications like readers
or viewers to the public at no charge. They know consumers will request
that programs take advantage of the free readers, and application
companies will be ready to pay royalties to allow their software to provide
the functions requested by the consumers.
