It includes everything from the central processing unit (CPU) to the monitor, keyboard, and mouse. Understanding the different types of hardware and how they work together is essential for anyone who works with computers. In this article, we will explore the various components of computer hardware, including internal and external components, and the peripherals that connect to them. We will also discuss the importance of hardware maintenance, the latest advancements in computer technology, and factors to consider when choosing the right hardware for your needs. Whether you are a computer technician, a gamer, or simply someone who uses a computer for everyday tasks, this article will help you better understand the world of computer hardware. Introduction to Computer Hardware Computer hardware refers to the physical components that make up a computer system. It includes everything from the processor and memory to input/output devices such as the keyboard and monitor. In this article, we will explore the different types of computer hardware and their functions. What is Computer Hardware Computer hardware refers to the physical components of a computer system. It includes all the components that can be touched, seen, and used to interact with a computer, such as the monitor, keyboard, and mouse. Hardware is different from computer software, which refers to the programs and applications that run on a computer system. History of Computer Hardware The history of computer hardware dates back to the 1820s when Charles Babbage, an English mathematician, and inventor, designed the first analytical engine, which was considered to be the first mechanical computer. With time, more complex electronic computers were developed, including the first Intel microprocessor in 1971. Since then, computer hardware has continued to evolve, becoming

Breast cancer survivors (BCS) exhibit decreased physical function and quality of life (QOL) following cancer treatments. Resistance training (RT) may elicit positive changes in physical and mental well-being. This study assessed 27 BCS, pre-and post-intervention (six months) on the following variables: muscular strength (via one repetition maximum (1RM) of chest press and leg extension), physical function (via the Continuous Scale-Physical Functional Performance test) and QOL (via the Short Form-36 survey). RT consisted of two days/week of ten exercises including two sets of 8-12 repetitions at 52%-69% of their 1RM. A repeated measures analysis of variance revealed BCS significantly (p < 0.05) increased upper (71 ± 22 to 89 ± 22 kg) and lower body (74 ± 18 to 93 ± 24 kg) strength, total physical function (65.5 ± 12.1 to 73.6 ± 12.2 units) and the subcomponents of physical function: upper body strength (63.5 ± 16.3 to 71.2 ± 16.8 units), lower body strength (58.5 ± 14.9 to 68.6 ± 16.3 units), balance and coordination (66.5 ± 12.2 to 74.6 ± 11.6 units), and endurance (67.2 ± 12.0 to 75.0 ± 11.6 units). No changes were observed over time for subjective measures of physical function and QOL. Results showed RT could be an effective means to improve objective physical function in BCS. Further research is needed to clarify the effects of RT on subjective physical function and QOL.

very nice analysis of the statistics put together by United Health.  Give credit where it is due.  Good job United.

Tennessee ranks 39 in Health as determined by the United Health Foundation.  I disagree with some of the defining terms in "health", but the point is well taken.

Louisiana Health rankings as determined by the United Health Foundation.  This 49 ranking is down from 47.  Only Mississippi ranks lower.  Yet, the LSBME is the most restrictive.  Go figure.

When choosing a country for cost-effective spinal fusion surgery, India stands out as an excellent option. The price difference is significantly lower when compared to hospitals in other medically advanced countries such as the United States, the United Kingdom, the UAE, and Singapore.

Endocrine society clinical  practice guideline's state proves validity of salivary cortisol testing.  Statement: "the diagnostic sensitivity and specificity is said to be excellent (92-100%)" and " Measurement of salivary cortisol by ELISA and LC-MS/MS has been well validated in the United States"

Lead levels lead to increased risk of cardiovascular events at lower than previous thought levels.  Levels as low as 2mcg/dl found to be associated with increased cardiovascular mortality.  This equates to 38% of Americans.  The author concludes with this statement, "Although a 10-fold decline in blood lead levels has occurred in the United States in recent decades, current levels remain orders of magnitude higher than in pre industrialized times".
