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.

Career Tips in Commercial Real Estate Brokerage

The commercial real estate sales industry can be very rewarding to brokers and agents. That being said it requires focus and consistent effort if you are to reap real rewards and become a top agent.

Many salespeople join the industry with the hope that ‘things just start to happen’ as part of working for an agency or brokerage; unfortunately those salespeople do not last very long at all. After 6 months or so the reality of the market ‘kicks in’ with few if any commissions coming in.

It takes about 3 months of real effort to change your personal market conditions and your income. It is not a stop and start process. Things should happen to a plan and that will be a plan that you implement every day.

The agency or brokerage that you work for has little to do with the listings and clients that you create or serve. When you start working in the industry, start working hard on your commitment to personal success and progress. You will need a business plan or something similar that keeps you on task.

So what do you need to make the industry work for you? Try these for starters:

  • A good database that you keep up to date in all respects
  • A list of prospects and clients in your database that you can talk to in a continual way
  • Market knowledge and skills relating to your specialist property type
  • Sound and established negotiation skills for listing, inspections, marketing and negotiation
  • Excellent documentation skills relating to your property type, contracts, leases, and any other supplementary documentation
  • Personal drive and a passion for prospecting and selling
  • Excellent marketing skills in both direct, and indirect marketing
  • Communication skills that are advanced for the complexities of property sale, leasing, negotiating and closing.
  • Good time management and documentation processes that allow you to start the day early with momentum and results.
  • Targets and goals that you can track.
  • Exclusive listings that you control for your clients.
  • Referral opportunities with established clients and prospects.
  • Clients that trust you and your skills to help them resolve property problems.

To give momentum to these things it requires deliberate effort. Every agent or broker has plenty of opportunity to rise up in the ranks of the market. The key to making it happen is ‘personal activity and planning’.

It should always be remembered that the commercial real estate industry and market is under change. As brokers and agents we should adjust to market conditions and not wait for the market to come to us.

Credit Card Processing

The credit card is a commonly used financial instrument and its use forms an important part of personal finance. A credit card though simple to use has a networked system and structure that enables payment through a plastic card with minimal chances of misuse and fraud. The credit card industry mainly enterprises of:

  • Card Provider: Cards providers are very few in numbers. Some of the known credit card providers are: VISA, MasterCard, JCB, American Express etc. The logos of these card providers are what we very often see on entry to a store.
  • Card Issuers: financial institutions such as banks issue a MasterCard or VISA or any other card to card holders. This card will have logos of both the financial institution and the card provider.
  • Card Acquirer: The card acquirer processes the cards accepted by any store and this service is known as credit card processing or merchant account services.
  • Merchant Account: The merchant or stores have an account with a credit card processing service to enable credit card payments in their store.

Every credit card transaction initiates a flow of information and exchange of money between the credit card processing organization, card issuer and the merchant account authorized and connected by the credit card provider.

Credit card processing services do not limit their services to acceptance of credit cards alone but also enable the processing of various payment mediums such as: debit cards, electronic checks, gift cards and other forms of payment.

The credit card processing organization fulfills the key task of authorizing the credit card when presented to the merchant instantly. The credit card processing organization then debits the card issuers account and credits their account with the amount of purchase made by the card holder.This entails that the card issuer pays the card processing services for the transaction. The card services organization then makes the payment to the merchant after deducting a transaction processing fee.

This is the procedure followed for every credit card transaction and it is made easy for you due to the efficiency of various parties that are involved in making credit card transaction an easy process.

Nature Photography – Five Tips For Great Rainforest Photos

Rainforest photography, like all good nature photography, is more about your sensitivity to nature than about expensive equipment. Of course you need a decent camera, and you must know how to use it. But the quality of your photos does not depend on the price tag on your camera. As long as you have a tripod, and a camera that allows you to adjust the aperture and shutter speed, you are set to go.

I make my living from nature photography, including a lot of rainforest photos, and I have never relied on the latest equipment for my work. Great rainforest photography is simply about finding an eye-catching subject, in good light, and having a creative eye for composition.

Note: The following tips are for photos of rainforest scenes, not for close-up photos of leaves, fungus etc.

Rainforest Photography Tip # 1: Choose a subject. As they say in the classics, "It's a jungle out there." In the rainforest, you are confronted with foliage, branches, roots, rocks, vines … in your face and all around you. A really good rainforest photo requires structure, to make some visual sense of all that clutter. Look for something that is immediately eye-catching – a big tree that dominates the trees around it; A root system that leads the eye; A waterfall or stream; In short, something that you can build a composition around.

Rainforest Photography Tip # 2: Use the best natural light. The mistake almost everyone makes at first is to take their rainforest photos on a bright sunny day when they are in the mood for a walk. Wrong! In full sunlight, the rainforest becomes a patchwork of light and shade that is impossible to expose properly. What you need is a cloudy day, when the light is much more even. Misty weather adds even more atmosphere to the rainforest, and can add a mysterious character to your rainforest photo.

Do not use a flash. The flash illuminated the scene with flat, white light, eliminating the gentle play of natural light and shade that gives the rainforest its character. Always use the natural light.

Rainforest Photography Tip # 3: Carry a tripod. Taking your rainforest photo under a heavy tree canopy, on a cloudy day (see rainforest photography tip # 2), means the level of light will be very low. You may be shooting at shutter speeds as slow as one or two seconds. You will always need your tripod, and it is best to avoid windy days so that the scene is as still as possible.

Rainforest Photography Tip # 4: Use a wide-angle lens (or a zoom lens, zoomed back to its widest angle). The wide angle lens has several advantages for rainforest photography. Firstly, it exaggerates the sense of perspective in a photo, creating a sense of three dimensional depth. Viewers of your photo will feel like they are looking not just at a rainforest, but into it. Secondly, the wide-angle lens has a naturally wide depth of field. With so much detail all around you, it is important that you can keep both the foreground and the background in focus.

Rainforest Photography Tip # 5: Stay on the path. There are some practical reasons for staying on the path when bushwalking. You minimize the possibility of getting lost, injured, or fined by some over-officious park ranger. The people who run the national parks are not stupid. They know what you want to see, and design their trails accordingly. Sticking to the path will not rob you of any great photo opportunities.

In terms of rainforest photography, you are able to create some distance between you and the foliage around you. It is much easier to photograph a tree when you do not have the branch of another tree in your face. By staying on the path, you can get a clear view of your subject, without interference. You can even use the path as part of the composition in your rainforest photo. It is an excellent way of inviting the viewer to join you on your walk in the rainforest.

So there you have my five rainforest photography tips. Notice they concentrate on light and creativity, not on fancy techniques or equipment. You can make great improvements in all your nature photography this way, regardless of what type of camera you have.
