In Unit II, we investigated ways that information systems (IS) can support collaboration, and we reviewed
Porter’s five forces model. In this unit, we will discuss the basic concepts of hardware and software. We will
also discuss open source software development and database management systems and compare the
differences between native and thin-client applications. Lastly, we will explore mobile systems and the
characteristics of quality mobile user experiences.

Title
A byte generally contains eight bits. A switch can be open or closed. An open switch represents 0 or off, and
a closed switch represents 1 or on. Bits are basic units of data, such as ones and zeros, while data can be
represented by variables such as numbers, images, graphics, and characters to name a few (Kroenke &
Boyle, 2017).
The categories of computer software are clients and servers. Personal computers (PCs) use non-mobile
operating systems (OSs) such as Microsoft (MS) Windows and Apple Macintosh (Mac) OS X. Remember that
OSs are developed for specific hardware and are often referred to as native applications. In other words, MS
Windows was created specifically for hardware-based PC systems, so you cannot install MS Windows on an
Apple Mac as a base OS, nor can you install the Apple OS on a PC-based.
This chapter introduces basic computer concepts such as defining computers and their components. It describes the five main components of a computer as the input, output, processing, storage, and communication devices. It discusses different categories of computers including personal computers, mobile devices, servers, mainframes, and embedded computers. It also outlines how computers are used in various fields of society such as education, healthcare, science, and manufacturing.

An operating system (OS) manages computer hardware and software resources and provides common services to programs. Gary Kildall developed the first PC operating system, which was text-based, and he pioneered operating systems by making his OS hardware-independent. The OS is essential software that allows computers to interact with users and run other applications. Common types of operating systems include time-sharing, multi-user, real-time, distributed, and embedded OSs. Key OS components are the kernel, networking, security, and user interface. Popular past and present OSs include DOS/360, Mac OS, UNIX, Linux, Windows, Android, iOS.

There are three main components of a computer system:
i) Input/Output Unit which allows the user to interact with the computer through input and output devices.
ii) Central Processing Unit (CPU) which controls and coordinates the operations of the computer by processing input data.
iii) Memory Unit which stores data, instructions, and output during processing.
The document provides details on these three components, describing the input, processing, and output functions of the computer system. It also discusses different types of computers based on size (microcomputers, minicomputers, mainframe computers, and supercomputers) and components of computer hardware.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
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.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

6. Processor: processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions.
7. Intel: Intel also makes motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphic chips, embedded processors, and other devices related to communications and computing.
8.
9. network switch: A network switch or switching hub is a computer networking device that connects network segments. A network segment is a portion of a computer network wherein every device communicates using the same physical layer. Devices that extend the physical layer, such as repeaters or network hubs, are also considered to extend the segment. However, devices that operate at the data link layer level or higher create new physical layers and thus create rather than extend segments.
