The operating system provides the framework for how you interact with your PC, and is essentially what you see when you turn on your computer. Small changes in the way it’s designed change how your computer looks, how and where you access files, plus the programmes and software you can run. There are three main operating systems, each with their own perks and drawbacks.
|Windows||Mac OS||Linux||Crome OS|
|Usage||In a DOS Laptop the Microsoft OS Windows can be installed||In a Apple Laptop the Mac OS Windows is always pre-installed||It is an open source of OS can be installed in a DOS Laptop and it is commonly used by Computer
|Works in Crome bookes only|
|Pre-installed & compatible Softwares||most software, accessories and components are designed to work perfectly with it.||Any Software to instal in this OS must be compatible to Mac OS||Very limited softwares can be installed in it even less than Mac OS. Some downloadable softwares such as mozila firefox, VLC media player can compatible to it.||Any Software to instal in this OS must be compatible to Crome OS. Google also offer their own online versions of popular desktop programmes, such as Google Sheets for Excel, or Google Docs for Word.|
|Drawbacks||It can take a while to learn the layout and navigation||OS X is limited in its choice of software and accessories||Can not be used for norma use||There are only a few offline apps so needs high quality internet for work effectively.|
The processor is the central brain of your computer, and is what makes the computer respond to your requests. It processes and manages everything you do on the computer, so a faster processor gives you a faster computer.
Certain software is more demanding on your processor, so you’ll need to check the minimum requirements of your preferred software before buying to ensure you have the power you need. You can check both product pages on our website, or ask one of our in-store colleagues who will check for you. Software packages will also outline system requirements before you purchase them.
Number of cores:
A core is the part of the processor that processes information. Cores come a variety of values, including dual-core, quad-core and octa-core. Generally, the more cores a processor has, the more information it can compute, and the faster it is. Every PC we sell has at least a dual-core processor. This means it can process more information, giving a more responsive experience when you’re browsing the web, opening files or playing games. Quad-core processors are more powerful and great for demanding software, such as video editing and music production applications, which are now designed to work best across several cores.
Clock speed refers to how fast your processor runs, and is measured in GHz. The higher the clock speed, the faster your computer will be at opening applications and loading software. Intel™ processors also offer Turbo Boost, while AMD has Turbo Core technology, which injects power solely for the task you are working on. This means the processor uses power more efficiently, and gives out less heat when it’s not running at maximum.
What is the right processor for me?
|1||AMD A6 / A10 /FX||1-4 Core||1.0 -1.6 GHz||Great value home computing not sute for content creation.|
|2||Intel Pentium||2-4 Core||1.1 -3.7 GHz||Quick, reliable everyday performance|
|3||Intel Core Duo||2-4 Core||1.2 -3.7 GHz||Ideal combination of fast performance and efficiency for most users, like browsing internet, watching movies|
|4||Intel Core™ i3||2-4 Core||1.9 -4.0 GHz||Ideal combination of fast performance and efficiency for most users. It can do all works by Pentium.|
|5||Intel Core™ i5||2-6 Core||1.9 -4.0 GHz||High performance processing for serious gaming and professional media creation. It can do all works by Core™ i3 and light photo and video editting, light Gaming, running of light softwares etc.|
|6||Intel Core™ i7||2-8 Core||2.4 -4.0 GHz||The ultimate in professional-level creative and business computing. It can do all works by Core™ i5 and proffesional photo and video editting, Heavy Gaming, running of heavy softwares etc.|
The memory cache is where tasks are stored before they are handled by the processor. The more memory cache you have, the more demanding tasks you can perform on your computer. The only time you need any more than 4 MB is when want to run professional-level creative software, like Cubase or Photoshop.
Intel® or AMD processor?
There isn’t a huge difference between the two brands, unless you’re running professional-grade software. To get the best computer for you, you’re much better off checking whether your PC has the features, hard drive and design to suit your needs.
If you do need higher performance, here’s a breakdown of both brands:
Intel™ processors are known to be slightly more powerful than AMD. If you’re looking for fast, smooth performance, an Intel® Cor™ i5 or i7 processor is a great choice, and can be found in many of the more high-end computers available today. These processors have Hyper-Threading technology, which doubles the performance of each core. This means a dual-core processor with Hyper-Threading offers the power of a quad-core processor, giving you a huge boost in performance.
AMD produce great APUs, or accelerated processing units. They combine a fast processor with a graphics card in one powerful chip, so you get awesome graphics on games and movies plus a fast experience when you’re switching between applications.
You can also get a dedicated graphics card for both processors, with the sole job of handling image and graphic quality for games, video making and graphic design.
Graphics Card :
A graphics card is a processor dedicated solely to handling the visuals on your PC. Dedicated graphics cards deal solely with visuals, videos and games. PCs with high-quality, dedicated graphics cards can handle the latest games and visual media, plus video and image editing software. If you like any of these things, and do them often, then it really is a must. You’ll also need one if you want to connect a 4K or high-resolution screen, as you’ll need serious power to get the best imagery. A good tip is to look for a PC with a high-end NVIDIA GeForce GTX card, or one of AMD Radeon RX Vega series.
|1||Usually Intel processors contain an integrated graphics chip which is sufficient for everyday needs||Nvidia and AMD are 2 popular companies making dedicated graphics cards. They are more powerful than integrated graphics card|
|2||PRO TIP Unless you plan to use the laptop for heavy gaming, an integrated graphics should serve your purpose.||Dedicated graphics cards are required for heavy gaming, photo & video editing|
RAM stands for Random Access Memory, and it’s where requests made by you are stored before the processor is ready to start working on them. The more RAM you have, the more you can do at the same time, such as playing music while switching between an Excel file and the Internet.
What does RAM do?
When you perform an action on a computer, anything from clicking open a Word file to opening your web browser, the request is sent to your RAM. When the processor is ready, it picks up the request and makes it happen. With small actions, this happens instantly.
Big software applications or having lots of open screens at once, however, fills up your RAM quickly. That’s why modern PCs have lots of built-in RAM and fast processors to cope with a backlog of requests if you’re running intensive applications.

Storage refers to the built-in memory you have to save documents, photos, music, software, apps plus everything else you want to store.
|SN||Hard Disk Drive (HDD)||Solid State Drive (SSD)||Solid-State hybrid Drive (SSHD)|
|1||It is a mechanical data storage system||It is a mechanical data storage system||
It is the combination of SSD & HDD
The hard disc drive is the central storage feature on most PCs, and is available in a variety of sizes – from 500 GB to a massive 3 TB. What size is right for you depends on how much music, files, games and other content you have.
|Solid-state drives don’t store as much as a hard disc drive or other storage devices, but they work much quicker, so are great for demanding graphics software or HD games. They normally work alongside a hard disc drive, so you can install games and software on them for the best performance without taking up overall storage capacity.||A solid-state hybrid drive gives you the memory capacity of an HDD with the smooth, fast performance of an SSD. An SSHD can loosely be described as ‘smart’ memory, as it learns which content you access most and stores it ready for you, offering instant access and a more responsive feel.|
|3||Hard disc drive (HDD) | An HDD is a standard hard drive for storing files, the type fitted to most desktop computers.||Solid-state drive (SSD) | SSDs are storage devices that are faster than hard disc drives (HDD), but have a lower storage capacity.||Solid-state hybrid drive (SSHD) | Solid-state hybrid drives combine the speed of SSDs and the capacity of SSHDs, although aren’t quite as fast as an SSD. They can intelligently measure and then predict which content you like to access, and have it ready for you when you’re most likely to access it.|
The form factor refers to the size, shape and style of your PC. There’s a wide selection to choose from, and each size and style has its own benefits. What’s right for you depends on what you want from your PC, and how much space you have.
Tower PC: Function over form
Tower PCs are the classic, full-size PCs you normally store underneath a desk. Though recent versions are smaller than their more bulky equivalents a few years ago, they are still larger than more modern mini-PCs or laptops. Go for a tower PC if you’re looking for more power to run design software, advanced games or film making applications.
Thanks to extra internal space, you can also customise and add upgrades much easier, plus enjoy a wider variety of more specialized software, from the latest graphics cards for immersive gaming, to professional music-making software like Pro Tools.
All-in-one: Slim, stylish, versatile
All-in-one PCs have a tower PC setup built-in to the monitor, which takes up less room and gives you more flexibility.
Some all-in-one PCs, such as Windows, feature touchscreens like on a tablet, giving you a more responsive way to control your PC. Simply touch, tap and swipe the screen to navigate the web and your applications.
Mini PC: Fits into any space
Mini-PCs are a new breed of PC. Despite being the smallest available, they work just like their full-sized counterparts, with the same ports, features and ability to run advanced software.
Mini PCs are great for everyday computing tasks, such as typing essays and browsing the web, but don’t have the same room for high-performance components or upgrades as larger tower PCs. As technology improves, however, mini-PCs are catching up fast with their larger counterparts.
With powerful processors and dedicated, enhanced graphics cards, gaming PCs are designed to give the ultimate gaming experience for the most modern, advanced games. Every gaming PC we currently sell will play any PC game available today. The main difference between the more expensive versions and the more affordable is that you’ll get better visuals and higher frame-rates for a more immersive experience.
If you have a 4K TV or monitor, you can also enjoy high-definition visuals on-screen for more lifelike gaming.
All-in-one screen sizes
All-in-one PCs come in a range of different screen sizes and styles with an array of awesome features.
You’ll be able to find an all-in-one PC whatever your tastes and available space, as they range from a compact 19” to a huge 34”. Go for a larger screen if you need it for work and require access to range of pages or applications. If space is at a premium, then there’s a great range of powerful mini all-in-one PCs to choose from.
All-in-one PCs are available with HD or Full HD screens.
Which screen resolution is right for you depends on how you use your PC. If you watch lots of movies or play lots of games, then Full HD gives you more detailed visuals. If you use your PC for average everyday tasks, however, then a normal HD screen will be sufficient and save you money, too.
Touchscreen PCs let you simply tap, swipe and pinch the screen to do everything from browse the web to playing fun online games. It’s super intuitive to use, so everything you do is fast, simple and responsive.
Other things to consider
Whether it’s design, software or extra storage, there’s a range of smaller details to think about when trying to find your perfect desktop PC.
Many modern desktop PCs have attractive, contemporary styling, with smooth, rounded edges, sleek metallic builds and minimalist modern colouring. If you’re after a computer that looks and works great, then the best option is modern mini-PCs, which look at home next to the latest sleek tech devices, like smartphones and smart TVs.
Contemporary all-in-one PCs also look great, as they don’t clutter your desk with cables and the slim bezels on the latest designs offer a clean, minimalist look, such as Apple’s all-in-one PC, the iMac.
You can also customise gaming PCs with cool colouring and lighting, which you can sync with some controllers for a truly unique look.
