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.

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.

Advantages and Disadvantages of Online Classifieds

If you want extra traffic to your website, online classifieds are the way to go. Online classifieds are similar to newspaper classifieds. The only difference is that newspaper classifieds are only viewed by the people in the area that the newspaper was written for. Online classifieds can reach a global audience. So the amount of traffic one can receive is unlimited. There are several advantages and disadvantages to using online classifieds for business.

One advantage is the amount of time it takes to write and post an ad. It should take no longer than twenty minutes to write a good ad and post it to a classified directory. They are a quick method for advertising for internet marketers who don’t have a lot of spare time and want to increase their results.

Another advantage is that online classifieds produce quick results and require very little physical effort. Placing an ad can bring traffic to a website almost instantly. If done correctly, one can generate a boat load of traffic from classifieds.

A third advantage is that this strategy is very low cost. You can post to many classified sites for free. It is great for anyone who doesn’t have any money to advertise with or anyone who has a small budget.

One disadvantage of this type of advertising is that an ad will expire quickly. The ad will drop lower and lower in the rankings until it is not generating any traffic at all. The ads must constantly be replaced. Consistency is the name of the game. Keep posting ads daily and the results will speak for themselves.

Another disadvantage of this type of advertising is that one must post to many classified sites to see big results. Advertising on one site is not enough to produce great results. Take it to the next level and send ads to about 5-10 classified sites.

Overall, online classifieds are a great way to generate extra traffic to a website. It is quick and easy and does not cost a lot of money.

Know When Your Business Needs IT Consulting Services

Businesses must ensure that only the latest technologies and software are deployed at the workplace, in order to provide quality solutions to their clients, and to be ahead of the competition. With the ever-changing technological trends in the industry, businesses find it cumbersome to adopt these technologies. Instead they can hand the entire function over to a sound IT consulting services company – who in turn will tap into their global pool of highly skilled IT professionals, who have the advantage of working in various IT environments, and have extensive experience across sectors. By providing assistance to business, IT consulting services providers free up existing resources; ensure IT transitions are smooth and problem-free; optimise key business processes; identify areas that benefit with further cost saving; build competitive advantage through IT; reduce IT complexities; provide IT strategy consultancy services, IT project management services and provide specialised programme management solutions – all of which, help the organisation achieve significant business efficiencies and cost benefits.

Choosing to work with an IT firm definitely boosts a company’s overall efficiency, which in turn decreases costs. Firms tend to look for a flexible and bespoke solution to address the client’s IT needs, thereby delivering solutions that are in tandem with the client’s goals.

The advantages listed above necessitate hiring an IT company. But how will a business know that it needs IT consultancy services?

A business may function with its existing IT architecture without knowing the benefits of such services. In order to discern the need for IT consulting services, businesses must first understand the details of their services. According to Wikipedia, ‘IT consulting is a field that focuses on advising businesses on how best to use IT to meet their business objectives. In addition to providing advice, IT consultancies often estimate, manage, implement, deploy, and administer IT systems on businesses’ behalf, known as Outsourcing’. IT consulting services firms thereby help businesses strategise and evaluate their IT functions as a whole and take the necessary steps to implement and/or deploy and then administer effective and robust IT systems in place. Businesses can seek the services of an IT firm when:

  1. IT investments regularly overshoot the set budget. Fast-paced technologies and trends warrant proper planning. When making strategic use of the allocated budget seems difficult, seeking the advice of IT consultancy services providers is imperative.
  2. A business decides to relocate or reduce staff.
  3. Projects regularly miss deadlines. Lack of specialists, complex projects and shoestring budgets lead to inefficient project management. A sound IT consulting services company designs bespoke, safe and cost-effective solutions, either full time or part time.
  4. Challenges of globalization, technical and regulatory changes arise. Business and technology management when integrated help the business survive, and therefore IT strategy consultancy is important.
  5. Programmes and projects eat into the budget. A business needs specialised programme management solutions to achieve significant cost savings. A robust IT services company provides either the co-sourcing or the outsourcing model to help businesses remain ahead of the competition, by providing tailored solutions.
  6. There is a need to change networks or when the need to shift to a new IT architecture arises.
  7. The company is in need of a robust disaster recovery plan.
  8. There are no data storage systems in place.

Availing the services of the right IT consulting services company may be a challenge. A business must choose a provider before the problems stated above get worse – and must choose a provider who is able to set in place a sound IT system in place. Therefore, a business must choose a provider who provides flexible solutions. Businesses must also remember that though they think they are able to fix small issues, the reality is that these issues must be treated at the root, and they can be properly tackled only with strategic IT solutions – only provided by an effective IT consulting services company.
