Energy Conservation

The Role We Can Each Play

=========================

We can all play a part in lessening our reliance on fossil fuels.

A- Use low-energy lamps such as CFL replacements for as many incandescent lightbulbs as possible in our home or apartment.

B- Turn off all lamps in areas where they are not needed.

C- Turn down water heater temperature to between 120-125 degrees.

D- Seal your home or apartment from obvious air drafts.

These steps could save the average family $300. to $400. a year in electricity costs alone, lessening the fossil fuel needed to produce it. It certainly becomes plainly obvious that if all Americans stopped driving their automobiles and ceased all commercial transportation, which includes both ground and air travel, we would most likely not be importing any foreign oil and would likewise be exporting at least some of the oil that we produce here. Obviously, this is not feasable.

Lately, most governments of the world have made it their priority to begin to deal with the problems of energy consumption and how to deal with the over consumption of fossil fuels along with Renewable energy sources. Many are adopting the latest in renewable energy technology such as Wind Power and Solar Power generation. Many have begun new projects that when completed will save millions of dollars on imported oil, domestic use of oil, or other fossil fuels.



Renewable Energy is the road to take. We must now tame this new source to be more competitive and more reliable than its predecessors which have been a source for many decades earlier. Today, we are learning this taming process very quickly and as we adopt these new technologies they will become more rewarding. Eventually, it is hoped, the oil wells of the world will wane into a minority source of energy.

With Renewable Energy in the news of late and the phenominal increase in Windmill farm deployments in 2004 and 2005 along with greatly expanded use of Solar Energy in this same period in many areas of this country, it is hoped that this trend will greatly lessen our needs for Fossil fuel sources in the near future.

 

Popular Auto Navigation Systems

   While technology is constantly evolving it is fairly safe to say that there are some toys that are better suited to remain at the top of the heap than others. The story really is no different when it comes to auto navigation systems. These systems each have different bells and whistles and while there is no one system that is perfect for everyone, there are a few systems that are consistent best sellers.

It is important that you as a consumer know what is available in navigational tools before leaping and buying the first thing you see. There are many neat buttons and features that can really turn a girls (or guys for that matter) head if she isn’t sure of what she will actually need and use in her (or his) travels. Knowing what you need, what you would like, and what you are fairly certain you can live without willmhelp you get the best possible bargain for your auto navigation system dollar.

FAST CHARGING

 What is  fast charging ?

Generally fast charging  is the concept of charging any device at the faster rate as compared to the normal charging speed. Normally we use to charge the device with 5 watt charger. But now a days there are chargers available in the market which can charge the device with more than 30 watts. Now a days there are so many companies which gave fast charger support to the cell phone devices along with a fast charger. 

 How fast charging mechanism works ?

       Fast charging is a must have feature in today’s phones. It keeps our batteries topped up through busy days. However, there are a variety of different standards from different companies. Some only work with specific cables and chargers, while others use higher voltages. It can all get a bit confusing, so we’re here to make sense of it.

      In a nutshell, fast charging increases the current sent to the battery to fill up its capacity quicker. The basic USB specification only sends 0.5 amps (A) of current using 5 volts (V) for just 2.5 watts (W). Fast charging technologies boost these figures. Huawei’s 10V/4A SuperCharge produces 40W and Samsung’s latest Adaptive Fast Charging produces 15W of juice. Some Chinese companies even boast charging technologies that can hit up to 100W. All fast charging services share a common theme — more power.

Advantages of fast charging :

1. It charges your device more faster than normal charging.

2. It saves your time.

Disadvantages of fast charging :

1. It decreases the life span of battery.

2. Fast charging produces more heat which harms the battery and also the device.

What is computer memory?

 COMPUTER MEMORY

       Memory is the most essential part of the computer. Memory is the storage part of the computer. We need to store the data. This storage enables us to use stored data in the future. Computer memory is mainly divided into Primary memory, Secondary memory, and Cache memory. The memory and storage devices are measured in terms of bits and bytes. The measurements used are 0, 1 binary digit.

1. Primary Memory :

Memory units are the storage areas in the computer. The term "memory" usually refers to the main memory of the computer, whereas the word "storage" is used for the memory that exists on the desks, CDs, etc. The main memory is usually called a physical memory which refers to the 'chip'  ( Integrated Circuit) capable of holding data and instructions. 

There are different types of memories as follows :

a. Read-Only Memory ( ROM ) :

ROM chip

    

 In ROM, the information is burnt or pre-recorded into the ROM chips at the manufacturing time only. Once data has been written into the ROM chip, it cannot be erased but you can read it. When we switch off the computer, the contents of the ROM are not erased but remain stored permanently. ROM is a non-volatile memory. ROM stores critical programs such as the programs that boot the computer.

b. Programmable Read-Only Memory ( PROM ) :

PROM chip

 PROM is the memory on which data can be written only once. A variation of the PROM chip is that it is not burnt at the manufacturing time, but can be programmed using PROM programmer or a PROM burner. PROM is also non-volatile memory.

c. Erasable Programmable Read-Only Memory ( EPROM ) :

EPROM chip

In EPROM, the information can be read and re-programmed using a special PROM-programmer. EPROM is a non-volatile memory. An EPROM differs from a PROM in that a PROM can be written only once and cannot be erased. But ultraviolet light is used to erase the contents of the EPROM.

d. Electrically Erasable Programmable Read-Only Memory ( EEPROM ) :

EEPROM chip

   

 EEPROM is a recently developed type of memory. This is equivalent to EEPROM but does not require ultraviolet light to erase its contents. It can be erased by exposing it to an electrical charge. It is also a non-volatile type of memory. EEPROM is not as fast as RAM and other types of ROM. Flash memory is a special type of EEPROM that can be erased and re-programmed.

e. Random Access Memory ( RAM ) : 

RAM chip

   RAM is the most common type of memory found in modern computers. This is the place where programs get stored temporarily. When the CPU runs a program, it fetches the program instructions from the RAM and carries them out. If the CPU needs to store the results of the calculations it can store them in RAM. When we switch off the computer, whatever is stored in the RAM gets erased. It is a volatile form of memory.

 Types of RAM :

*  EDO RAM ( Extended data output RAM ) : 

      EDO RAM is a type of random access memory chip that improves the time to read from memory on faster microprocessors such as the Intel Pentium. EDO RAM was initially optimized for the 66MHz Pentium.

*  SRAM ( Static random-access memory ) :

    It is a type of semiconductor memory that uses bistable latching circuitry to store each bit. The term static differentiates it from dynamic RAM ( DRAM )  which must be periodically refreshed. SRAM exhibits data remanence but is still volatile in the conversational sense that data is eventually lost when the memory is not powered. 

2. Secondary Memory :

        As primary memory is volatile, the computer uses secondary memory to store data, programs, etc. Secondary storage is also called backup storage. Secondary storage can be used to transmit data to another computer either immediately or at a later time. This provides a mechanism for storing a large amount of data for a long period of time. Some of the commonly used secondary storage devices are hard disk, magnetic tapes, floppy disks, and CD-ROM. To understand the physical mechanism of secondary storage devices one must have basic knowledge of magnetism, electronics, and electro-mechanical systems. The average time required to reach a storage location and obtain its contents is called access time.

 ex-

  * Hard disk drive :

     

 The hard disk is a magnetic disk on which you can store computer data. The hard disk is a direct- storage medium. This means you can store and receive the data randomly. Disk storage systems are essentially based on magnetic properties. 

* Floppy disk :

FDD

    The floppy drive uses a thin circular disk for data storage. It is a soft magnetic disk. It is a thin magnetic coated disk contained in flexible or semi-rigid projective jackets. The disk rotates at 360rpm. Floppy disks are slower to access than hard disks and hve less storage capacity. It is less expensive and is portable. It can be assembled randomly.

3. Cache Memory :

       The cache is a small amount of high-speed memory, present between the primary school and CPU. There are two levels of cache memory L1 and L2, L1 cache memory will present inside the data or instructions. Usually with a memory cycle time comparable to the time required by the CPU to fetch one instruction. The cache is usually filled from the main memory when instructions or data are fetched into the CPU. Often the main memory will supply a wider data word to the cache than the CPU requires, to fill the cache memory rapidly.

WHAT IS IMFORMATION TECHNOLOGY?

INFORMATION TECHNOLOGY :

Information technology is generally considered to store, transmit and manipulate data. It also includes the development, maintenance, and use of computer software, hardware, and networks. It is typically used within the context of business operations. It is considered as the subset of information and communication technology.

      An information technology system (IT) is generally a communication system, information system, or more specifically a computer system, that includes all hardware, software, and peripheral equipment operated by a group of users. It includes their use for the processing and distribution of data. Generally, data means information, facts, statistics, etc. Gathered together for reference, storage, or analysis.

Information technology is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Many different products and services within an economy are associated with information technology. Incorporate world, it is the entire scope of all the jobs that are related to computers and technology in business.

What is a supercomputer?

   Supercomputer, is a  system specifically build to perform various scientific and industrial challenges at or near the currently fastest operational rete for computer.This computer performs at high level as compared to general purpose computer. The performance of a super computer is generally measures in floating point operations per second (FPOS).

  1.FIRST GENERATION COMPUTERS (1940-1956):VACCUME TUBES

* The first generation computers used vacuum tubes for switching circuits and magnetic drums for memory.

 *They were large in size ,occupied a lot of space and produced enormous amount of heat . 

 *They were very expensive and consumed large amount of electricity. 

 *First generation computers operated only on machine language.

 *First generation computers could solve only one problem at a time.

  2.SECOND GENERATION COMPUTERS (1956-1963):TRANSISTERS

*In the second generation computers vacuum tubes were replaced by transistors. 

 *Due to the use of transistors computers became smaller ,more faster and economically more reliable. *It produces less amount of heat compared to first generation computers.

 *It used punched cards for inputs and printouts for outputs.

 *Second generation computers moved from machine language to assembly language ,which allowed programmers to specify instructions in words.   

 

    3.THIRD GENERATION COMPUTERS(964-1971):INTIGRATED CIRCUITS

*In the third generation computers integrated chips were used ,in which transistors were made smaller in size and placed into silicon chips which dramatically increased the speed and efficiency of computers. 

 *In third generation computers keyboards and monitors were used instead of punched cards and printouts.

 *the computers were interfaced with operating systems which allowed solve many problems at a time.

  4.FOURTH GENERATION COMPUTERS(1971-PRESENT):MICROPROCESSORS

*In the fourth generation computers microprocessors were used in which thousands of integrated circuits were built into a single silicon chips.

 *These computers were small and more powerful.

 *They could be linked together to form networks ,which eventually led to the development of internet.

  5.FIFTH GENERATION COMPUTERS(PRESENT):ARTIFICIAL INTELLIGENCE

*The fifth generation computers ,based on artificial intelligence.

 *These computers are still in their developmental stage.

 *fifth generation computers will come close to bridge the gap between computing and thinking.

ARTIFICIAL INTELLIGENCE

Artificial intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn from past experience. Since the development of the digital computer in the 1940s, it has been demonstrated that computers can be programmed to carry out very complex tasks—as, for example, discovering proofs for mathematical theorems or playing chess—with great proficiency. Still, despite continuing advances in computer processing speed and memory capacity, there are as yet no programs that can match human flexibility over wider domains or in tasks requiring much everyday knowledge. On the other hand, some programs have attained the performance levels of human experts and professionals in performing certain specific tasks, so that artificial intelligence in this limited sense is found in applications as diverse as medical diagnosis, computer search engines, and voice or handwriting recognition.
