Basic fundamentals of computer
This document provides information about computers, including the full form of "computer", who is considered the father of the computer, the basic parts of a computer, and examples of common input and output devices. It explains that a computer is an electronic device that needs user instructions to work and defines input devices as peripherals that allow users to input data and control signals, and output devices as peripherals that receive and display results from the computer's processing. Examples of both input devices like keyboards, mice, and touchscreens and output devices like monitors, printers, and speakers are listed.

The document discusses input and output devices used with computers. It describes input devices as those that enter raw data into the computer, like keyboards, mice, scanners, and sensors. Input devices are categorized as either manual, requiring human operation, or automatic, which input data without human involvement. Output devices are those that communicate the processed results from the CPU to the user, such as computer monitors, printers, speakers, and actuators that control real-world devices. The central processing unit processes input data and produces outputs that are easy for users to understand.
Basic organization of computer
A computer has basic hardware components that allow it to accept data through various input devices like keyboards and mice, process the data in the processing unit and memory, store data, and produce output through output devices like monitors and printers. The main hardware components are the input unit, processing unit, memory unit, output unit, and storage. The input unit consists of direct input devices like keyboards and pointing devices, as well as audio and video input devices. The output unit provides soft copy output through monitors and speakers, and hard copy output through various printers and plotters.

April 2012 newsletter
This document discusses tax deferral in qualified retirement plans and how future taxes on withdrawals can pose risks. It tells the story of Damocles, who realized the dangers of a king's lavish lifestyle when he saw a sword hanging above the throne. Similarly, retirement plan participants enjoyed tax breaks on contributions but face uncertain future tax burdens. Higher taxes or rates in retirement could mean participants pay more than the value of earlier deductions. The document examines options like Roth accounts that avoid this "sword of Damocles."
Testing antipatterns
This document discusses various testing anti-patterns and defects, including:
- Conflating behavior-driven development (BDD) with just using the Cucumber tool. BDD is about illustrating behavior through examples, not just using Cucumber.
- Defect reports that provide too little information or assume knowledge, like not including clear reproduction steps.
- Defect tickets that report multiple distinct defects instead of one per ticket.
- Inappropriate test automation, like rewriting code badly, not actually validating results, or focusing on UI testing without checking functionality.
The document advocates for clear, minimal defect reports and appropriate automation focused on checking functionality rather than UI interactions.

Joining provides tools to make better God-aligned decisions, accelerate spiritual and professional growth, and ignite one's work with the spirit. The document encourages the reader to contact Ray or Kurt to learn more about joining a Kingdom Ablaze Business Community.
Cloud computing
Cloud computing relies on sharing computing resources over a network rather than local devices. It has evolved from mainframes to client-server models to today's cloud systems. The cloud is characterized by on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. There are several cloud service models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Cloud computing provides green benefits such as reduced hardware, energy usage, and emissions through server consolidation and virtualization.

Control Unit (CU)
The document discusses the control unit (CU) of a computer's central processing unit (CPU). It explains that the CU controls instruction execution sequence, interprets instructions, guides data flow, regulates timing, and handles tasks like fetching, decoding, and storing results. The CU has three main components: sequential logic, control unit registers and decoders, and control memory where microprograms are stored. The document also compares hardwired control units, which have fixed circuitry, to microprogram control units, which use replaceable microprograms stored in control memory.
