Computers and computing devices from different eras
A computer is a device that can be instructed to carry out arbitrary sequences of arithmetic or logical operations automatically. The ability of computers to follow generalized sets of operations, called programs, enables them to perform an extremely wide range of tasks.
Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers.
Since ancient times, simple manual devices like the abacus aided people in doing calculations. Early in the Industrial Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines did specialized analog calculations in the early 20th century. The first digital electronic calculating machines were developed during World War II. The speed, power, and versatility of computers has increased continuously and dramatically since then. Name

There's no need to pack on pounds or fall ill this autumn.


A nip is in the air, as summer eases into the fall season. Football season starts, and so does school. The holidays are right around the corner. So is the flu season. To help keep you healthy over the next few months, we've got these tips:

1. Take a Tailgate Time-out


It's an all-American past-time -- the tailgate party! Tailgating today has progressed far beyond burgers and chips. You'll find everything from cheese dip to spicy chicken wings.
Don't despair: Your tailgate spread doesn't have to sideline your weight loss plan. Grilled kabobs are great fare on the field. Just skewer veggies, fruits, and lean meat, and soak in your favorite marinade. Seafood, salsas, wraps, and stews are good eating, too. A Crock-Pot of chili -- loaded with high-fiber, high-protein beans -- is a classic tailgate dish (don't forget the Beano).
Just remember, alcohol is packed with calories. Enjoy your favorite brew, but switch it out for zero-calorie beverages as the party rolls along. It's all in how you play the game!

2. Sleep Tips to Help Kids' Weight


Does your child get enough sleep?  sleep and being overweightSleep shortfalls may increase hunger hormones -- so kids eat more. Also, kids are less likely to get exercise (and burn off calories) when they're tired.

If not, it could affect more than sleepiness at school. Studies suggest there may be a link between skimping on

Women over 60 are already at a greater risk forosteoporosis than men, and Tufts University researchers found that drinking soda, including diet soda, compounds the problem. They discovered that female cola drinkers had nearly 4% lower bone mineral density in their hips than women who didn't drink soda. The research even controlled for the participants' calcium and vitamin D intake. Additionally, a 2006 study published in theAmerican Journal of Clinical Nutrition found that cola intake (all kinds, not just diet) was associated with low bone-mineral density in women

A recent study presented at a the American Academy of Neurology meeting found that over the course of 10 years, people who drank more than four cups or cans of soda a day were 30% more likely to develop depressionthan those who steered clear of sugary drinks.

The correlation held true for both regular and diet drinks, but researchers were sure to note that the risk appeared to be greater for those who primarily drank diet sodas and fruit punches. Although this type of study can't prove cause and effect, its findings are worth considering.

It makes drinking more dangerous

Using diet soda as a low-calorie cocktail mixer has the dangerous effect of getting you drunk faster than sugar-sweetened beverages, according to research from Northern Kentucky University.

The study revealed that participants who consumed cocktails mixed with diet drinks had a higher breath alcohol concentration than those who drank alcohol blended with sugared beverages. The researchers believe this is because our bloodstream is able to absorb artificial sweetener more quickly than sugar.

Excessive soda drinking could leave you looking like aBreaking Bad extra, according to a case study published in the journal General Dentistry. The research compared the mouths of a cocaine-user, a methamphetamine-user, and a habitual diet-soda drinker, and found the same level of tooth erosion in each of them. The culprit here is citric acid, which weakens and destroys tooth enamel over time. (Related: 20 Things That Can Ruin Your Smile)

Its sweetener is linked to headaches Early studies on aspartame and anecdotal evidence suggests that this artificial sweetener may trigger headaches in some people. "I have several clients who used to suffer from migraines and pinpointed their cause to diet soda," Bjork says.

It could lead to weight gain, not weight loss

Diet soda is calorie-free, but it won't necessarily help youlose weight. Researchers from the University of Texas found that over the course of about a decade, diet soda drinkers had a 70% greater increase in waist circumference compared with non-drinkers. And get this: participants who slurped down two or more sodas a day experienced a 500% greater increase. The way artificial sweeteners confuse the body may play a part, but another reason might be psychological, says Minnesota-based dietitian Cassie Bjork. When you know you're not consuming any liquid calories, it might be easier to justify that double cheeseburger or extra slice of pizza.

It confuses your body

Artificial sweeteners have more intense flavor than real sugar, so over time products like diet soda dull our senses to naturally sweet foods like fruit, says Brooke Alpert, RD, author of The Sugar Detox.
Even more troubling, these sugar stand-ins have been shown to have the same effect on your body as sugar. "Artificial sweeteners trigger insulin, which sends your body into fat storage mode and leads to weight gain," Alpert says.

Bubble trouble


When taken at face value, diet soda seems like a health-conscious choice. It saves you the 140-plus calories you'd find in a sugary soft drink while still satisfying your urge for something sweet with artificial sweeteners like aspartame, saccharin, and sucralose. But there's more to this chemical cocktail than meets the eye.


Drink coffee to have a better nap

In a Japanese study that examined how to make the most of a nap, people who took a "coffee nap"—consuming about 200 milligrams of caffeine (the amount in one to two cups of coffee) and then immediately taking a 20-minute rest—felt more alert and performed better on computer tests than those who only took a nap
.
Why does this work? A 20-minute nap ends just as the caffeine kicks in and clears the brain of a molecule called adenosine, maximizing alertness. "Adenosine is a byproduct of wakefulness and activity," says Allen Towfigh, MD, medical director of New York Neurology & Sleep Medicine. "As adenosine levels increase, we become more fatigued. Napping clears out the adenosine and, when combined with caffeine, an adenosine-blocker, further reduces its effects and amplifies the effects of the nap."

Women's Health Tips: Diet, Exercise, and Stress Relief - WebMD

Looking for the path toward a healthier you? It's not hard to find. The journey begins with some simple tweaks to your lifestyle. The right diet, exercise, and stress-relief plan all play a big role.

Follow a Heart-Healthy Diet

There's an easy recipe if your goal is to keep away problems like heart disease and strokes.
  • Eat more fruits and veggies.
  • Choose whole grains. Try brown rice instead of white. Switch to whole wheat pasta.
  • Choose lean proteins like poultry, fish, beans, and legumes.
  • Cut down on processed foods, sugar, salt, and saturated fat.
When eating healthy, flexibility often works best, says Joyce Meng, MD, assistant professor at the Pat and Jim Calhoun Cardiology Center at UConn Health. If you like to follow a strict diet plan, go for it. If not, it's OK. "Find what works for you."
