Unlike other electronic devices, computer is the sum of its parts. Nobody cares about the specifications and make of the picture tube of a particular brand of television. But in the case of computers, more than the brand name the specifications of its components like processor, motherboard, RAM, hard disk, and suchlike are the things that a knowledgeable consumer first asks about. Here is computer hardware terminology in a nutshell.

Processor or microprocessor is a powerful IC chip on which a number of functions are incorporated. It is the heart and brain of the computer rolled into a chip. Its efficiency depends on its speed of processing, which is specified by its frequency and it is denoted using gigahertz. The higher the speed, the better will be its functioning. Also, there are several types of processors such as 32-bit processor and 64-bit processor. The bit rate is not actually a yardstick of speed. The larger bit rate means the processor will be able to efficiently do several computing processes at the same time.

Another main item in computer hardware terminology is motherboard. In simple terms, it is the platform on which all the other components are electrically fitted in. Over the years, a number of additional functionalities such as sound card, graphics card, and networking card are slotted on to the motherboard. When selecting motherboard, one should make sure that the motherboard is compatible with other components such as processor, hard disk, and RAM.

Hard disk and RAM are the next items in the hierarchy of computer hardware terminology. A computer has two types of memory. Permanent memory is stored magnetically on hard disk and it will be stored in the disk even after the computer is shut down. On the other hand, RAM or random access memory will be off once the computer is shut down. It is the kind of memory on which the functional information while running a computer, like running programs and unsaved data, are kept when computer is running. When you save a file, the data is stored to hard disk from RAM.

Nowadays the memory capacity of hard disk is skyrocketing. It is all set to break the upper limits of gigabytes. Comparing to that, RAM was a slow starter. It is still ambling along the lower middle part of gigabytes. Lay users do not need a RAM with a large capacity. The price of RAM increases with the rise in memory capacity.

Computer peripherals like keyboard, mouse, monitor, CD or DVD drives and writers, speaker, and webcams are all part of a large list called computer hardware terminology. There are other hardware items also such as graphics card, sound card and video card for sound recording and video editing facility, and internal and external modems for browsing the internet.

E waste is one of the most serious issues that has engulfed the whole world. The obsolete computers, if not treated properly can become a major source of toxins and carcinogens. Rapid technology change, low initial cost and even planned obsolescence have resulted in a fast growing environmental concerns across the globe. Though many countries boast of technical solutions but in most cases a legal framework, a collection system, logistics and other services need to be implemented before a technical solution can be applied. E waste comprise 2% of America’s total trash and 70 percent of overall toxic waste. In the United States, an estimated 70% of heavy metals in landfills come from discarded electronics.

Recycling is one of the most effective ways to prevent the hazard of e waste. Many material used in the construction of hardware can be recovered and recycled. Reuse of tin, silicon, iron, aluminum, and a variety of plastics – all present in bulk in computers – is possible and can reduce the costs of constructing new systems. Electronic devices like including audio-visual components (televisions, VCRs, stereo equipment), mobile phones and other hand-held devices, and computer components, also contain valuable elements and substances that are suitable for reclamation. Powering and cooling computers is an increasing contributor to global warming and the power it consumes also contribute to a negative effect on the environment.

In this regard, various government as well as non government agencies have taken significant initiatives to curb it. One of the main organisation that takes the responsibility of checking the e waste is CFA, that installs various measures to aware computer hardware manufacturers as well as consumers about the hazards of e-waste. Information on the dangers involved in improper disposal of computer hardware is provided to the computer labs. The supply of quality hardware is also restricted to beneficiaries only. CFA provides comprehensive on-site ICT support to beneficiaries, ensuring the equipment functions for the longest possible time with the greatest positive impact.

To counter this further, Userful desktops are being deployed all around the world with a typical configuration of six stations per computer. Research has shown that Userful products can reduce electronic waste by up to 80 percent, further decreasing its environmental footprint. It was supported by the data that stated that in the past year, Userful desktops have helped to minimise the computer hardware waste by 29,000 tons of CO2 emissions, which is equivalent to taking more than 5,000 cars off the road.

The consumers too need to get sensitive about the whole issue when the impact of computer hardware on environment, is in discussion. We should look for eco friendly ways to dispose off the computer waste and follow the recycling programmes all over the country. There are various companies like Sony, Toshiba and Gateway that offer take back programmes that provide monetary incentives for recyclable and/or working technologies. One should go for reuse and up gradation of the present PC unless it is very essential to dispose off. Selling off the old computers to the used product market is another option.

The camcorder is everywhere. For over twenty years people have used camcorders to record school plays, field trips, family trips and anything that needed to be recorded in some fashion for future generations to remember. Camcorders have moved from being large and bulky to a simple device that fits easily into the palm of one’s hand. People have become almost dependent on these small electronic devices that have changed the way we cherish our memories.

One of the most revolutionary inventors of our time is Jerome Lemelson. In 1980, he gained a patent on the camcorder. According to records, he had tried to gain the patent in 1977, but the patent office of the United States denied him because the idea seemed too absurd at the time. Many other high tech devices can be attributed to Lemelson, including the ATM, the Walkman and the VCR. This is one man who completely changed the way in which people store memories.

When a person thinks of camcorders, they most likely do not consider the internal components. Inside those small digital handycam recorders are many components, including a mini VCR. The handy cams are so tiny that one may have a hard time believing this, but in every type of camcorder, this crucial component exists. Also included inside is a CCD, which helps measure the light used to show the images, as well as lens and motors that deal with zoom, focus and aperture.

A camcorder is a wonderful item for a person to own. This video recorder allows a person to capture important life events with just a click of a few buttons. A person can capture their wedding, the birth of a child or basically their entire lives for future generations. The media will not fade into nothing, like the still camera pictures of yesteryear. Recording special events has never been more technologically advanced!
