There are several reasons you may want to go with laptop computers instead of desktops.
Advantages of a Laptop to a Desktop
One of the most powerful merits of a laptop computer is portability. You can afford to pick and drop it in the boot of your car or just in your bag and rush down for a seminar presentation, board meeting, training session or any event that needs the use of a computer with less hassle.
But desktop computer on the other hand is bulky and has many peripheral parts you must carry to have a complete computer system to work with.
Besides, you could just place the device on your laps in case there is no table space unlike the desktop which you must make a table space for.
All laptop computers come with batteries that last for sizeable number of hours. This enables you continue your work in case of sudden power outage. While desktop computers have no batteries but depend on external power backup sources such as Uninterruptible Power Supply (UPS), inverter etc. which are expensive to purchase and even maintain. You wouldn’t want your work to be disrupted due to power failure hence the need to go for a laptop instead.
Laptops often are designed with some extra features to enhance user experience for example Bluetooth, webcam, wi-fi, etc.
Desktops on the other hand will have to require that you purchase the said devices and install separately which is most times challenging in terms of cost and time.
Laptop screen technology offer more appealing graphic display to enable one enjoy pictures, video games and movies quality compared to desktop screens. A laptop series such HP Spectre x360 has sophisticated screen display power that will allow users enjoy compared to desktop of the same time and configuration.
Its keyboard is arranged in such a way that keys are easily accessed and located even by beginners. But because of the large space on desktop keyboards, often times beginners have to wander covering long distances to locate some keys during use.
Greater Resale Value
Laptops have higher resale values compared to desktops. After years of usage, you will be sure of still parting with your laptop device at a reasonable amount. But desktop computers go for much less and buyers tend to underrate and under prize them.
Laptops generate lesser ewaste compared to desktops computers. For quite some years now organisations and individuals have invested much on protecting the environment.
Technologies recognize this fact hence reduce number and size of components that come with laptop products.
While desktop computers still come with numerous and size able components that later cause serious environmental ewastes.
Laptop consumes less energy compared to desktop systems.
While it consumes as little as between 15 to 25 watts, desktops guzzle as high as 150watts. Therefore, if you want a computer with lesser energy requirement, laptop may just be the solution.
Due to popular request to make some comparison between two powerful, elegant and advance MacBook Pro 2015 and HP Spectre x360 laptops by our fans and followers, we have decided to embark on the review and comparison exercise.
Perhaps, one of the major steps in wanting to acquire any of such devices after making some savings towards it is to ensure you have the right information as a guide to avoid regrets after purchase.
Both laptops are great devices with excellent speed, design, configuration and awesome finishing.

Hackers are capable of anything when talking about the safety of websites online especially wordpress sites.
Part of the challenges of having websites online like wordpress site is due to the activities of hackers.
Hackers are capable of so many terrible things on the internet.
Like the pirates in the sea, highway robbers etc., the aim of hackers is always to compromise information in online resources.
Hackers are people who are always out to find and exploit weaknesses on computers or computer networks.
There are different reason why hacking is often done, its either to make profit, challenge the expertise of someone, enjoy it as a game or even protecting something they feel is not pleasant to them.
There are two major types of hacking, ethical and unethical hacking.
This involves hacking activity that is legal and permissive. For instance, if an operating system password can no longer be remembered yet the owner of the computer wants the password removed. If someone breaks into the computer with his or her permission to help out, it is referred to as ethical hacking.
Ethical hackers normally require permission and authority to hack most times, they are commissioned or paid to carry out the hacking.
It is sometimes inappropriate for such personal details to be displayed to the world without verifying from the owner of the details.
On the other hand, several Facebook account owners in most cases do not even know that such details are been viewed by their profile visitors.
An incident happened a couple of years back when a friend complained that she receive strange calls. But after investigations, she realized they got her number from her Facebook profile.
Of course, up till now most Facebook profiles still have profile owner’s phone numbers displayed. What I can’t phantom is whether the said owners of the accounts are aware but intentionally allow them there.
In any case, it is understandable for Facebook pages belonging to businesses or organisations as such phone numbers are meant to connect clients with the business owners.
As for me, I wouldn’t want my personal details like phone number , email or even date of birth to be published on my profile to the full view of all visitors. I could choose only my friends or family to view them.
Hide Your Age
After logging in to your Facebook account, you will need to follow the steps below:

Click on Edit , a drop down menu will appear. Scroll down and Click on Only Me

If you want every visitor to see the Date of Birth, select Public. But if you will prefer only your friends’ friends then select Friends of Friends option.
Repeat same process for Birth Year, Email, Gender and the rest of others if you so wish to hide them from public view.
Through Facebook pictures, friends and relative who may have lost contact can easily identify and get connected to someone.
Through them we have an idea of how a person is faring to a reasonable extent. Perhaps that explains why it has become common knowledge that people put the very best of them on our profiles.
Updating pictures by changing profile pictures is a way to make our Facebook followers and fans have fun viewing our profile regularly.
Besides, some Facebookers will for some personal reasons want to delete completely their profile pictures but maybe stocked.
This article is to teach you step by step on how to change your Facebook profile picture without any hassle.
Before we proceed, we must bear in mind that Facebook recommends image size of 160X160 Pixels . Although 180 x 180 can be accepted however, Facebook will by itself adjust it automatically from 180 pixels to the recommended size.

There are strong indications that Laptop radiations have adverse health effects on human health. Although there are conflicting opinions on whether or not such laptop radiations are harmful. Studies have continued to show that humans have limited intensity of radiation their bodies can withstand beyond which might become harmful and dangerous to the well-being of man.
Laptops are portable computers that can be carried around in a handy way and even placed on laps to work.
There have being various studies on electromagnetic radiations from electronic devices especially laptop computers .
Truth be told, all other electronic gadgets such as television, cell phones, microwave ovens, Wireless routers etc. emit such radiations as well, but what makes those of laptops critical is the fact that laptops are often carried on laps or even much closer to human systems .
The said closeness to human bodies shortens the distance between the electromagnetic frequencies waves and the human body.
Ionizing radiation is an energy type released by atoms that move in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha). The automatic continuous disintegration of atoms is called radioactivity, and the excess energy emitted is a form of ionizing radiation.
World Health Organisation- W.H.O report of 2012 declared after research that certain amount of such radiations beyond a particular level can be injurious to human health and possess the tendency to cause health hazard. According to W.H.O the following facts were deduced from their findings.
There are almost uncountable reasons why every business needs a website.
