Electronic World – How We Use Electronics in Daily Life

Using electronics today is so much a part of our daily lives we hardly think of the way the world would be without electronics. Everything from cooking to music uses electronics or electronic components in some way. Our family car has many electronic components, as does our cooking stove, laptop and cell phone. Children and teenagers carry mobile phones with them everywhere and use them to take and send pictures, videos, and to play music. They send text messages on the cell phone to other phones and to their home computers.

Wireless internet is becoming more common all the time, with laptops set up in cyber cafes where people can drink coffee and check their email all at the same time. The computer user can do all the web searching in relative privacy thanks to the electronic accessories which can be added to the computer. Conversely, more and more transactions are being sent electronically across the airwaves so security is becoming a larger issue than ever before. Merchants who sell products online must be able to assure their customers that information submitted at a website is not being accessed by unauthorized personnel.

Music is a prime user of electronics, both in recording and in playback mode. Stereos, record players, tape decks, cassette players, CD drives and DVD players are all the result of advances in electronics technology in the last few decades. Today people can carry a playlist of hundreds of songs around with them easily in a very small device–easily portable. When you add Bluetooth or headphones the music can be heard by the user, but does not disturb those nearby.

Electronics technology in cameras has increased dramatically. A digital camera is available to most Americans at a price they can afford and cellphones often includes a fairly sophisticated digital camera that can capture still pictures or even video pictures and store them or transfer them to a computer where they can be saved, shared digitally with family or friends or printed out in hard form with a photo printer device. Pictures obtained through a camera or by means of a scanner can be edited, cropped, enhanced or enlarged easily through the marvel of electronics.

Literally thousands of everyday devices that we use constantly make use of electronics technology in order to operate. These are products ranging from automotive engines to automated equipment in production settings. Even artistic efforts benefit from computer modeling prior to the committing of valuable artistic media to create the finished product.

Electronics devices are being used in the health field, not only to assist in diagnosis and determination of medical problems, but to assist in the research that is providing treatment and cures for illnesses and even genetic anomalies. Equipment such as MRI, CAT and the older X-rays, tests for diabetes, cholesterol and other blood component tests all rely on electronics in order to do their work quickly and accurately. Pacemakers and similar equipment implanted in the body is now almost routine.

Culinary Arts and Nutrition

Imagine yourself in a room full of tempting food, jellies, chocolates, pastries, cakes, pizzas and much more mouth watering dishes. Slurp… I know by now you are too tempted to get to the market and buy yourself a nice, juicy burger, coke and an ice cream tub or are ready to order a pizza, rather than reading.

Just for a moment think of the chefs who stay in the kitchen all day long that is loaded with scrumptious cuisines giving out such enticing and alluring aromas. It must be really tough for them to resist the delicacies they prepare for their customers. One the other hand, if they start tasting every dish they prepare it will be extremely tough for them to sustain good health.

It is said, ‘People judge a book by its cover’, and the same applies to a cook too. A healthy and fit chef ascertains us that he is health conscious and knows all about good and rich cooking. This might not prove true in all cases; some guys do not have such luck. There are many professional chefs are surrounded by buttery carbohydrates, rich sauces, creamy puddings and fine succulent meat but are thin like a Cornish wafer.

The roly-poly chefs that we were accustomed to once, are replaced by much more disciplined, controlled and healthy chefs. There was a time when a thin chef was not trusted but today the scenario has totally changed. The more lean and fit a chef is the more energetic he will be. A chef should be prepared to bounce around the kitchen in order to do everything just right.

Being a chef, it is important to taste every dish and every dessert prepared to ensure it is delicious. In doing so the fats keep on settling on the stomach, in turn making you fat. To avoid this, it is better to take small mouthfuls in intervals. Small meals ensure better metabolism. Some chefs believe in drip free food and indulge in raw fresh fruits, raw vegetables and much water. They also avoid any sort of meal in between lunch and dinner. Lastly, a good 20 minutes walk each day. In case you do feel hungry at night, eat a bowl of cereal.

A chef is however known for his skills in cooking and preparing meal yet his physical appearance and nutritional habits also play an important role. Not only does it attract more customers for him but is also important for his own good.

Nutrition is also an important aspect of cooking delicious foods. And chefs are not an exception to this rule. While pursuing their education in the culinary arts, one of the subjects that these aspiring chefs study is Nutrition. Here, they learn about the amount of nutritive elements present in each ingredient – and how to analyze and determine which foods have how much nutritive value.

No doubt, this knowledge goes a long way in helping these chefs create delicacies that are not only tasty but also healthy for their customers.

Define Computer Hardware

It is quite well known that the working of the computer is pulled by hardware and software. One can define computer hardware as the electronic, magnetic, and electric devices that carry out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C++, and Photoshop are the software parts of the computer. A good example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the software parts.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by software applications. For example, let us see what happens when you click the print button of the web browsing software. The software application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the software will get a positive response from the processor. Then the software application provides instruction to the printer via the processor to print the web page. In that sense, hardware parts are the foot soldiers and software applications are the commanders in the digital operation that takes place within a computer.

The main player of computer hardware is undoubtedly the microprocessor. It is the sun in the solar system of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a number of functions are incorporated. Two specifications determine its efficiency. One is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to carry out multiple operations at the same time.

One cannot define computer hardware without mentioning the two types of memory used in computers. One is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Another important product that one should mention when one defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There are several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.
