In MS-Dos (Disk Operating System) There are two types of Basic dos commands they are internal dos commands and external dos commands which are used separately to perform specific task or operation. Internal dos commands are those commands which are included in command processor (command.com). Internal dos commands are built in command.com file and while the computer has been booted this file or commands are loaded in the computer memory and you can use this basic dos commands while computer is ON.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Â
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Â
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
Â
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

1. The iOS is developed and maintained by Apple. [True]
2. Real Time and Multi Threading Operating System behaves same like each other. [False]
3. Booting is the process of storing the Operating System into the Hard Disk. [False]
3. 4. Tracking of files and folders is the File Management functionality. [True]

D.Answer the following questions:
1. What is an Operating System?
Ans. An Operating System is a System Software that manages and serves other programs and
also provides an interface for the user to interact with a computer.
2. Why is an Operating System needed for a Computer System?
Ans. An operating system is the driving force for using the computer. It provides a software
platform, on top of which, other programs, called application programs are executed. The
application programs are designed in such a way that it can run on the environment of a
particular operating system.
3. State one difference between Multiprocessing and Multitasking Operating System.
Ans. Multiprocessing Operating System supports and allocates programs on more than one CPU (or
processor). Multi-tasking operating System on the other hand allows several applications to be
loaded and simultaneously used in the memory. But the processor handles only one
application at a particular time and is capable of switching between the applications giving a
feeling that each application is getting executed simultaneously.
4. What is the function of a Distributed Operating System?
Ans. Distributed operating system allows software and data to be distributed around the system.
The software and files are stored on different storage devices which are located in
different geographical locations and may be accessed from different computer terminals
using this operating system.
5. Name the different functionalities associated with an Operating System.
Ans. The different functionalities associated with an Operating System are:
• Booting the Computer
• Processor Management
• Device Management
• Memory Management
• File Management
• User Interface
• Application Program Interface(API)
• Protection and Security
4. 6. State the process of Booting in a Computer System.
Ans. Booting refers to the process of powering on a computer and getting into the operating system.
During the boot process, the computer will perform a self-diagnostic, also known as a POST
(Power On Self-Test) and load necessary drivers and programs that help the computer and
devices communicate into the RAM.
7. Give two functionalities of the Processor Management.
Ans. Two functions of the Processor Management of an Operating System are:
• The operating system keeps track of the processor and the status of process.
• The operating system allocates the processor (CPU) to a process.
8. What do you understand by the term device management?
Ans. The operating system is responsible for managing device communication via their respective
drivers. The device driver is a specialized program that acts as a path between the operating
system and virtually all hardware not on the computer’s motherboard. The device driver acts as
a translator between the electrical signals of the hardware subsystems and the high-level
programming languages of the operating system, application and utility programs.
9. State two functionalities of the Memory Management of an Operating System.
Ans. The two functionalities of the Memory Management of an Operating System are:
• The operating system keeps track of the main memory and checks which part is in use and
by which process. It also keeps track of the part that is not in use.
• The operating system makes a decision on which process will get memory when and by how
much. Thus each process must have enough memory in which to execute, and should not overlap
the memory space of another process nor be run into by another process.
10. What is File Management?
Ans. The file management capability of an operating system is responsible for the way files and
folders are efficiently stored in the secondary memory. Accessing such files and folders in the
easiest possible manner is also its responsibility.
11. What is “User Interface”? What are the two possible User Interfaces of an Operating System?
Ans. User Interface refers to the environment through which a user interacts with the computer. The
two popular user interfaces are:
• Character User Interface (CUI)/ Command Line Interface
• Graphics User Interface (GUI)
12. State two security features that an Operating System can provide.
Ans. Two security features that an Operating System can provide are:
• It lets the resources of the computer to be used in a consistent way.
• It prevents unauthorized access to the computer.
13. Name the different layers in an Operating System Model.
Ans. There are five different layers in an Operating System namely:
• User Interface
• File Management System
• Input / Output
5. • Memory Management
• Kernel
14. What is a Kernel?
Ans. The Kernel of an Operating System refers to the lowest layer of the operating system. It acts
as a regulator for the whole system, controlling the allocation of time slices to users or
processes and ensuring that resources are allocated fairly. The kernel is responsible for
multi-tasking, process control, exception handling (on error handling) and interrupt
processing.
15. What made Android Operating System so popular?
Ans. Android Operating System is popular in hand-held devices not only it is because it is free,
but is also a stable version available for download in public environment.
