This document discusses the five generations of computers from vacuum tubes to artificial intelligence. The first generation used vacuum tubes which were bulky, unreliable and required air conditioning. The second generation used transistors which were smaller but still required maintenance. The third generation used integrated circuits which generated less heat but still needed air conditioning sometimes. The fourth generation used microprocessors which were the smallest yet and generated negligible heat. The fifth generation involves artificial intelligence and has advantages like being noninvasive but also has disadvantages like being expensive and requiring operator understanding.

computer is a calculating machine which is used to perform arithmetic and logical operation at a high speed.
A computer is an electronic device that can accept, store and process information to produce the required result.
Therefore, we can define computer as a device that transforms data. Data can be
anything like marks obtained by you in various subjects. It can also be name, age, sex,
weight, height, etc. of all the students in your class or income, savings, investments, etc.,
of a country.
Computer is a device that can solve any mathematical operation and it
operates on information or data.
Computer can be defined in terms of its functions. It can (i) accept data
(ii) store data, (iii) process data as desired, (iv) retrieve the stored data

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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.

11. Functioning Of Computer
(i) Input- Computer accepts the input given by the user it can be in
the form of instructions or commands to do computer to operate on
the data it could be a single command to do a task or a set instructions
to preforms a series of steps this set of instructions is called a
programme.
(ii) Storage and Retrieval- The input is stored in the memory of
computer and it can be Retrieved whenever required.
(iii) Processing- The execution of instructions given to the computer
is called processing.
(iv) Output- Final result or output, available to the user, either on the
monitor (soft copy) or as a print out (hard copy) is called output.
