Binary number system (part 1)
Download as pptx, pdf0 likes86 views
The binary number system uses only two digits, 0 and 1, while the decimal system uses ten digits, 0-9. Binary is useful for computers and digital electronics because circuits can be designed to represent "on" and "off" as 1 and 0. A single binary digit is called a bit, while 8 bits form a byte. To convert between binary and decimal, binary uses place values like decimal (ones, twos, fours, eights etc.) and decimal uses long division, with remainders becoming the binary digits.

Binary System by Bray Avila
Binary System by Bray Avilaavilab The binary number system uses only 1s and 0s to represent all data that computers process. It was first described in ancient India and introduced by Gottfried Leibniz in the 17th century. Claude Shannon later used binary code in his thesis which helped establish its practical use in computers and electronics. Braille is a common example of binary code used in the real world. Binary represents numbers in base 2 rather than base 10, with each binary digit called a bit and 8 bits making a byte of data.

It explains that computers only understand 1s and 0s and that multiple bits can represent numbers or characters. The document contains tasks for converting binary numbers to decimal and binary to text. It also discusses how the number of bits a computer can process at once determines its speed.
Number system
Number systemBangabandhu Sheikh Mujibur Rahman Science and Technology University The document discusses different number systems including decimal, binary, octal, and hexadecimal. It defines the base of a number system as the number of digits used. To convert between systems, integers are divided successively by the new base until the quotient is zero, while fractions and exponents are multiplied successively by the new base until the fractional part is zero. Common number systems include decimal with base 10 using digits 0-9, binary with base 2 using digits 0-1, octal with base 8 using digits 0-7, and hexadecimal with base 16 using digits 0-9 and A-F.

Digital ElectronicsMallela Niteesh Kumar Reddy The document provides an overview of digital number systems and codes. It discusses binary, octal, hexadecimal, signed magnitude, one's complement, two's complement and excess representations. Binary is the base system for digital circuits due to its two voltage levels. Negative numbers can be represented using the sign bit in signed magnitude or by taking the complement. Two's complement is commonly used as it allows addition/subtraction of positive and negative numbers without checking signs.

10 lesson3Mary Grace Uminga This document provides an introduction to mensuration and number systems in computing. It defines mensuration as geometry applied to measuring magnitudes, lengths, areas, or volumes from given dimensions or angles. In computing, measurements are "virtual" rather than using tools, as computers understand binary digits (0s and 1s) and bits are the smallest unit of information. Number systems classify how numbers are represented and have different bases, with the most common being base 10, while binary is base 2 and used in computer machine language. Octal is base 8 and groups binary into sets of three, while hexadecimal is base 16.

But what about the smaller, more subtle indicators that quietly shape your application’s performance and stability? we explored the hidden layer of performance diagnostics that too often gets overlooked: micro-metrics. These small but mighty data points can reveal early signs of trouble long before they manifest as outages or degradation in production.
From garbage collection behavior and object creation rates to thread state transitions and blocked thread patterns, we unpacked the critical micro-metrics every performance engineer should assess before giving the green light to any release.
This session went beyond the basics, offering hands-on demonstrations and JVM-level diagnostics that help identify performance blind spots traditional tests tend to miss. We showed how early detection of these subtle anomalies can drastically reduce post-deployment issues and production firefighting.
Whether you're a performance testing veteran or new to JVM tuning, this session helped shift your validation strategies left—empowering you to detect and resolve risks earlier in the lifecycle.

How John started to like TDD (instead of hating it) (ViennaJUG, June'25)
How John started to like TDD (instead of hating it) (ViennaJUG, June'25)Nacho Cougil Let me share a story about how John (a developer like any other) started to understand (and enjoy) writing Tests before the Production code.
We've all felt an inevitable "tedium" when writing tests, haven't we? If it's boring, if it's complicated or unnecessary? Isn't it? John thought so too, and, as much as he had heard about writing tests before production code, he had never managed to put it into practice, and even when he had tried, John had become even more frustrated at not understanding how to put it into practice outside of a few examples katas 🤷♂️
Listen to this story in which I will explain how John went from not understanding Test Driven Development (TDD) to being passionate about it... so much that now he doesn't want to work any other way 😅 ! He must have found some benefits in practising it, right? He says he has more advantages than working in any other way (e.g., you'll find defects earlier, you'll have a faster feedback loop or your code will be easier to refactor), but I'd better explain it to you in the session, right?
PS: Think of John as a random person, as if he was even the speaker of this talk 😉 !

AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATION
AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATIONmiso_uam AI-ASSISTED METAMORPHIC TESTING FOR DOMAIN-SPECIFIC MODELLING AND SIMULATION (plenary talk at ANNSIM'2025)
Testing is essential to improve the correctness of software systems. Metamorphic testing (MT) is an approach especially suited when the system under test lacks oracles, or they are expensive to compute. However, building an MT environment for a particular domain (e.g., cloud simulation, automated driving simulation, production system simulation, etc) requires substantial effort.
To alleviate this problem, we propose a model-driven engineering approach to automate the construction of MT environments, which is especially useful to test domain-specific modelling and simulation systems. Starting from a meta-model capturing the domain concepts, and a description of the domain execution environment, our approach produces an MT environment featuring comprehensive support for the MT process. This includes the definition of domain-specific metamorphic relations, their evaluation, detailed reporting of the testing results, and the automated search-based generation of follow-up test cases.
In this talk, I presented the approach, along with ongoing work and perspectives for integrating intelligence assistance based on large language models in the MT process. The work is a joint collaboration with Pablo Gómez-Abajo, Pablo C. Cañizares and Esther Guerra from the miso research group and Alberto Núñez from UCM.

zOS CommServer support for the Network Express feature on z17
zOS CommServer support for the Network Express feature on z17zOSCommserver The IBM z17 has undergone a transformation with an entirely new System I/O hardware and architecture model for both storage and networking. The z17 offers I/O capability that is integrated directly within the Z processor complex. The new system design moves I/O operations closer to the system processor and memory. This new design approach transforms I/O operations allowing Z workloads to grow and scale to meet the growing needs of current and future IBM Hybrid Cloud Enterprise workloads. This presentation will focus on the networking I/O transformation by introducing you to the new IBM z17 Network Express feature.
The Network Express feature introduces new system architecture called Enhanced QDIO (EQDIO). EQDIO allows the updated z/OS Communications Server software to interact with the Network Express hardware using new optimized I/O operations. The new design and optimizations are required to meet the demand of the continuously growing I/O rates. Network Express and EQDIO build the foundation for the introduction of advanced Ethernet and networking capabilities for the future of IBM Z Hybrid Cloud Enterprise users.
The Network Express feature also combines the functionality of both the OSA-Express and RoCE Express features into a single feature or adapter. A single Network Express port supports both IP protocols and RDMA protocols. This allows each Network Express port to function as both a standard NIC for Ethernet and as an RDMA capable NIC (RNIC) for RoCE protocols. Converging both protocols to a single adapter reduces Z customers’ cost for physical networking resources. With this change, IBM Z customers can now exploit Shared Memory Communications (SMC) leveraging RDMA (SMC-R) technology without incurring additional hardware costs.
In this session, the speakers will focus on how z/OS Communications Server has been updated to support the Network Express feature. An introduction to the new Enhanced QDIO Ethernet (EQENET) interface statement used to configure the new OSA is provided. EQDIO provides a variety of simplifications, such as no longer requiring VTAM user defined TRLEs, uses smarter defaults and removes outdated parameters. The speakers will also cover migration considerations for Network Express. In addition, the operational aspects of managing and monitoring the new OSA and RoCE interfaces will be covered. The speakers will also take you through the enhancements made to optimize both inbound and outbound network traffic. Come join us, step aboard and learn how z/OS Communications Server is bringing you the future in network communications with the IBM z17 Network Express feature.

Binary number system (part 1)
- 1. BINARY NUMBER SYSTEM (Part 1)
- 2. INTRODUCTION The binary number system is a base-2 number system. This means it only has two numbers: 0 and 1. The number system that we normally use is the decimal number system. It has 10 numbers: 0-9. TERMS TO DEFINE: Binary, Number systems, bit, byte
- 3. OBJECTIVES: 1. understand why computers speak in binary 2. convert decimal numbers into binary and vice-versa 3. understand how media files are converted into binary
- 5. Binary Number Systems The binary number system is a base-2 number system. This means it only has two numbers: 0 and 1. The number system that we normally use is the decimal number system. It has 10 numbers: 0-9.
- 6. Why use binary numbers? Binary numbers are very useful in electronics and computer systems. Digital electronics can easily work with a sort of "on" or "off" system where "on" is a 1 and "off" is a zero. Often times the 1 is a "high" voltage, while the 0 is a "low" voltage or ground.
- 9. A digit in binary is called a bit. A collection of 8 bits is called a byte.
- 10. Converting from Binary to Decimal If you want to convert a number from binary to decimal, you can add up the "places" that we showed above. Each place that has a "1" represents a power of 2, starting with the 0s place.
- 14. Converting from Decimal to Binary. The easiest method of converting decimal to binary is by using long division. Example: Convert 2710 to binary. 210
- 15. 1. Divide the decimal number by 2, and record the remainder: 27÷ 2=13 (remainder 1 )
- 16. 2. Repeat this process over and over until we can’t divide the number by 2. Here, we used long division so we can see the remainders easily.
