DIFFERENCES AND SIMILARITIES BETWEEN TABLETS AND LAPTOPS

Differences between Tablets and Laptops

It’s vital to acknowledge a portion of the contrasts between tablets and what’s more laptops. A standout amongst the enormous distinctions is that absence of field serviceable parts in tablets and other versatile apparatuses. In turn, variety will be the reality that tablets and other comparable gadgets would normally not be upgradable. Some mobile devices, for example, smartphones, might bring upgraded memory cards or batteries, yet that’s around it. Also, these are normally not serviceable in the field on it is challenging ensure your safety from “Electrostatic Discharge” (ESD) when working with respect to these units. Some associations propose you achieve that gadget back of the lab to upgrades or parts swaps. Other units, for example, those iPad2 are not user-serviceable whatsoever, furthermore any endeavor in completing along these lines will void the warranty. Some associations use the guarantees that need aid built into these results through repair, upgrade, alternately reinstatement may be necessary, As opposed to attempting to do any worth of effort in-house.
With just a taught a laptop (or notebook) is really just a smaller, portable version of a desktop computer. Like the desktop computer, it contains a similar processor, similar volatile DDR RAM, and a hard drive that could possibly be solid-state, but regardless will most likely be plugged into an SATA port. It also has a keyboard, and a touchpad that is similar to a mouse. All this hardware is designed to make the best use of operating systems (such as Windows) that you would normally find on a desktop computer. Tablets, on the other hand, use ARM-based processors and use nonvolatile flash memory that is hard wired to the system instead of a magnetic or solid-state hard drive. So, as you can imagine, the tablet has a loss of performance when compared to a laptop. In addition, the tablet utilizes an onscreen keyboard and doesn’t require any type of mouse due to the touch screen capability. All this hardware is designed to run mobile device software such as Android or iOS.


Tablet and Laptop Similarities

Although there are many differences, there are also a few similarities between laptops and tablets. For example, some laptops can be purchased with touch screen displays that work in the same manner as with a tablet. Also, the laptop uses a lithium-ion battery, and the tablet uses a lithium-ion polymer battery, smaller and customizable, but similar to their recharging techniques. Additionally, you can add on devices such as keyboards to your tablet. Both devices make use of various wireless communications such as WLAN, Bluetooth, and GSM.

Mobile Devices Operating System

Mobile Devices Operating systems (OSes)

An ever increasing amount individuals are replacing starting with desktops what’s more laptops with smaller lightweight versatile apparatus for example, tablets and cell phones. They are discovered everywhere: on the train, on buses, on airplanes, on boats etc.
Versatile apparatuses use different hardware over PCs and laptops. Keeping in mind that they are still computers, however, little ones; they contain a CPU, RAM, Storage device, color display, outer ports, et cetera.
Mobile devices also use different software than PCs and laptops. The two main operating systems in use, today are Android and iOS, open-sourced and the other vendor specific (closed source) respectively. A mobile operating system (OS) is a software that allows smartphones, tablet PCs and other devices to run applications and programs (Rouse, 2015). Open source OS means, allowing developers to modify the OS and freely create applications for it. Vendor Specific or Closed sourced not available for download to developers. Only specific hardware uses this operating system.

Which is the best OS and why? The List below shows the four most popular mobile OS on the market:
  • Android OS
  • IOS
  • Blackberry OS
  • Windows OS

Users of mobile devices select them base on the categories which are;
  • Cognitive load (how easy is it to use the OS when you first encounter it)
  • Efficiency and integration (how well all the OS's main features work together, such as multitasking, notifications, etc.)
  • Customization being able to manipulate through the created features and settings
  • User experience friction (how well the user interact with the phone using senses)
  • Affordability the ability to purchase the device
  • User Preferences what the user likes
  • Architecture the way in which the phone was designed, both hardware and software, drivers support etc.


Which is the best mobile operating system created?
In order to answer this question, Scientists finds a way to break down the functions of a mobile OS into components that highlight a particular use case and rate the OS on its ability to handle that task

Mobile Devices

MOBILE DEVICES ARE CHANGING THE WAY PEOPLE SOCIALIZE.



Mobile devices have become the technologic tool of communication; for the most part, creating a virtual interaction among people, allowing tele-cocooning and inducing technology overload among users. 

Virtual communication differs in many ways from those in face-to-face interaction; it has been this way because of the characteristics of computer-mediated communication (CMC). CMC lacks many of the auditory and visual cues which are normally associated with the emotional aspects of interaction, thus creating a virtual face-to-face interaction. Virtual communication has many advantages including increasing productivity, reduced business cost and a better work-life balance of the workforce (Communicaid Group Ltd, 2015). Also, it allows the equity in the ability to share thoughts and ideas, creates virtual classrooms, and makes reliable portability. While avatars and headsets are very useful in casual conversation, they do not satisfy the desire to communicate intimately very well.

Mobile devices encourage Tele-cocooning today. Tele-cocooning is described as the intimate human computer interaction, specifically referring to the communication of one person to another without the physical interaction (Case, 2011). The perception of tele-cocooning is the choice of many people today, usually with the most effective systems of technology. These systems allow for faster, effective and efficient ways of communicating and sharing knowledge back and forth. One of the major risks of tele-cocooning is that persons involve can be out of physical face-to-face interaction with humans for a while, thus resulting in anti-anthropomorphism. Additionally, it can also cause a person to develop an addictive reaction for their devices, resulting into a “Technology Overload.

”Technology Overload occurs when a person develops an addiction for their mobile device and cannot function for a second if the device becomes dysfunctional, misplace or lost. Most people enjoy the benefits technology brings to their lives, such as increase productivity, portability, virtual communication and more. However, an emergent problem is observed among people suffering from technology overload. People overloaded with technology often feel uncomfortable or nervous when they cannot use the internet, mobile phone, and or other mobile devices with a short length of time.


Finally, mobile devices have considerably impacted the way people communicate or socialize today. Mobile devices are virtualizing our world, as a result, bringing us closer together virtually, but distant in a real world perspective. Furthermore, people are being able to reduce productivity cost, share knowledge, and afforded the opportunity to experience ethnography with the use of mobile devices.
