In this modern day and age, society is driven towards comfort of life and simplicity in everyday tasks. We are constantly looking to get our hands on more advanced tools to be used as simply as possible. Computers have greatly contributed to enabling the average person to utilize such technology.
Given the prevalence of computers in society today, it is only natural that PC repair and service will occasionally be required, just as today's nearly ubiquitous automobile needs occasional maintenance and service as well.
The main difference between the various types of personal computers available today -- from desktop computers (PCs), and laptops (notebooks) to netbooks and tablets -- is their size. If you want power you have to sacrifice portability. If you want customization you have to sacrifice simplicity, etc.
A PC is a personal computer, usually refers to a Windows desktop computer, while the term can also include Macs. The central part of a PC is its computer case (tower), its size averages to about 19" x 19" x 9". Add to this a monitor, sound system and other components and you can see how its not considered portable.
However, its size enables it to host a powerful CPU, GPU, RAM and HDD (or SSD) giving much needed power and digital space to the user. It is also completely adjustable, every component is upgradeable. They are the best when it comes to intensive work like CAD/CAM, scientific exploration or simply high-quality gaming. Personal computers can be networked to work as one system, share data and devices.
While Desktops are permanently stationed, laptops are designed to be portable. They are compact devices, having all parts of a PC installed in a single, foldable case, they provide mobility. The downside of course is less space for powerful components. A modern laptop can however perform almost all tasks a PC can, although usually with less speed. There are several types of laptops, depending on the purpose, it can be multimedia, design, business, gaming – different types and brands are used for different purposes.
Netbooks are ultra-portable computers, significantly smaller then an average laptop, they are generally much cheaper then laptops, but also less powerful. They are good for simple tasks like browsing the internet, watching videos, writing, etc. You can easily carry it anywhere you go but don't expect it to handle a lot of load.
All in One (AIO) desktop is a good choice for many people because of the simplicity and "sleekness" of its design. It has all its components combined into one device, but like a PC, it is intended to be permanently positioned in one location, but they are more portable than towers. AIO's usually feature impressive displays, with optional touch-screen technology and a solid computing performance. If you are considering a Windows 8 computer, AIO with a large display and a touch screen is good choice. All in all, it is a good family computer, perfect for video conferences and multimedia but also suitable for business.
Decade ago, we’ve seen PDA’s ,which are very different from modern tablets. Tablets today are thin and light-weight with touchscreens that respond to a touch of a finger, or multiple finger, at the same time. There’s no need for mouse or keyboard. They are connected to the internet, via Mobile Data or WiFi. Tablets are mostly used for entertainment and information purposes, but if you need serious work done, there are tablets for that too. They feature large screens (compared to smartphones) which vary between 7-12" and generally good battery life, often better than that of a laptop. Their hardware is very energy-efficient.
Top Windows 8 tablets offer full-PC experience, when it comes to software. You get full Windows with all its perks like the Office suite. Other tablets like the Apple’s iPad and a large variety of Android tablets are good all-around, offering tons of quality apps for entertainment and work. iPad’s use iOS, which has a very simple, icon-based interface, and comprehensive settings. It doesn’t offer much customization but it has the largest App selection. Androids are more versatile, customers can choose between a variety of different hardware and software editions, not to mention different manufacturers, but Android is a more fragmented operating system and as such it is less resistant to virus attacks and sometimes prone to instability.
We also have smartphones, the little brothers of the tablets. They are technically computers, as is anything which uses a microprocessor, but they are still primarily smartPHONES. Lately, wearable computers are also rising in popularity. Essentially, general computer applications (GPS, e-mail, database, multimedia, calendar) are integrated into watches, visors and even clothing. We have smart watches, fabric PCs and visors such as the Google Glass. And what would this be useful for? Well, safety could be improved by allowing users to communicate our position (GPS) immediately in case of danger. Wearables are also useful for tracking your health, as heart-rate can be monitored. Smart apps calculate your training if you are running, for example, providing you with useful feedback.
