Which operating system?

The operating system is the basic software that allows you to easily use your laptop and run programs and applications.
There’s a perennial debate over whether it’s better to purchase an Apple Mac or a device running Microsoft's Windows operating system.

Microsoft Windows
  • The most widely adopted system in the world
  • The newest version, Windows 10, builds on Windows 8 by integrating the start menu with the start screen
  • Windows 10 is designed to be cross-platform - one operating system, tailored for your device, whether it’s a PC, tablet or smartphone, with apps created to run across all three
  • Includes Cortana, your own personal assistant
  • There are a number of enhancements, such as the Microsoft Edge web browser
  • Windows 10 is compatible with all Windows 8 devices
  • Some new functions require specific hardware requirements, such as dual microphones for Cortana
Microsoft Windows logo
  • Apple’s latest operating systems
  • Move seamlessly between your MacBook or iMac and your other devices
  • Make and receive iPhone calls on your Mac, even if your iPhone is in another room
  • Send and receive both iMessage and SMS text messages on your Mac
  • Start an email, document or browsing session on one device and pick it up on another
  • Mac OS High Sierra comes with new functionalities and features
  • Talk to your Mac using Siri, so you can work even faster and more efficiently
  • Ask Siri to perform tasks without having to stop what you’re doing
  • Facial recognition helps you to organise and discover your best photos
  • It uses a new file system - Apple File System (APFS) that is faster and more secure

Google Chrome OS
  • Designed to be a fast, simple operating system
  • Ideal for people who are on the go and work online
  • Utilises web apps - programs that are accessed over the internet, with any saved changes you make to documents being stored in the cloud - and accessible from any other internet connected device
  • Automatically backs up your work to the cloud so there’s a smaller risk of you losing it
  • Includes built-in virus protection, making it easier to keep your important files safe

Features to consider

Laptop storage space
  • A hard drive disc (HDD) is your laptop’s built-in central storage system
  • They come in different sizes, measured in gigabytes (GB) and terabytes (TB)
  • The bigger the hard drive, the more applications and files can be stored
  • Some performance laptops come with solid state drives (SSD)
  • They’re useful for using advanced programmes as they’re faster
  • They also don't use moving parts to work, making them more reliable
  • Random Access Memory (RAM) allows your device to multitask and run smoothly
  • Measured in gigabytes - usually 8GB or 16BG per computer
  • You will need more RAM for running advanced games and design suites
  • Read-only Memory (ROM) is permanent memory storage for data that doesn’t change
  • Virtual memory is part of a hard disc used to store data on a temporary basis
  • It swaps it in and out of RAM as required


It’s a good idea to buy your computer with enough RAM and storage space to last you for at least five years. Bear in mind that operating system updates can take up a lot of room, as do photos and videos. How much you need depends how you use your computer - use our tables below to work out what would suit your needs.

RAM guidelines
The minimum for Windows and MacOS systems
Great for running both Windows and MacOS systems, as well as a lot of gaming
Perfect for demanding professional software and games
For gaming enthusiasts who want to run multiple apps and play all types of games, including VR

Most people will be fine with 8GB RAM.

HDD & SSD guidelines

The advantage of buying a laptop with both an HDD and SSD is that you could store your operating system and apps on the SSD and the rest of your files on the HDD. This would mean that your software would run faster than it would on an HDD.

SSDs are much faster than regular hard drives. Images will appear faster, game levels will load more swiftly, booting up will happen much faster, not to mention resuming from sleep-mode. They don't use moving parts to work, making them quieter and more reliable and use less battery power. Laptops with an SSD are unlikely to suffer any damage if dropped due to the lack of moving internal mechanisms.

For most people who aren’t heavy gamers, 64GB - 128GB SSD combined with a 1TB HDD would be plenty of storage.

32GB - 64GB
 Basic computer tasks will run quickly
 A good option if you use multiple programs simultaneously
 Best if you’re a gamer oruse a lot of media files
 For gaming enthusiasts

If you’re buying a computer with either an SSD or an HDD then you will need more storage overall.

As an example, 1TB could hold: 17,000 hours of music, 1000 hours of video, 310,000 images and 500 hours of movies. However, these quantities would vary from person to person because each file comes in a different size, depending on length and quality.

Also, some people may store more video files than music files, for example. To make an assessment it’s best to look at your current computer storage - analyse how much storage you already use, and what type of files take up most space.


If you decide to increase the storage space or running speed on your computer at a later date, solid state drives, RAM and additional hard drive upgrades are available to buy from certain suppliers.

An alternative way to free up memory is to use online (cloud) storage such as Box, DropBox, iCloud, OneDrive, Google Drive or Amazon Drive. All of these offer between 2GB - 15GB of free storage.

Graphics (video) cards
  • Calculates the colour, position and size of all objects on the screen
  • ‘Shared’ or ‘integrated’ graphics cards use the computer’s built-in RAM
  • For example, Intel’s HD Graphics and AMD’s Radeon HD ‘G’ series
  • They provide superb visual performance for everyday use, such as watching HD videos and viewing photos
  • Advanced or ‘dedicated’ graphics cards enable you to run complex games or design packages more smoothly
  • Dedicated graphics cards have built-in RAM to perform with increased power
  • The NVIDIA GeForce range and AMD’s Radeon HD ‘M’ series are vital for those who love advanced image and video editing, as well as games
  • 3D cards are often a prerequisite for many of today's best-selling games
Processor or Central Processing Unit (CPU)
  • Also known as the microprocessor
  • The brain of any laptop, controlling all functions and actions
  • Its speed is measured in megahertz (MHz) or gigahertz (GHz), respectively millions or billions of cycles per second
  • Different processors are designed for different computing tasks
  • The most undemanding tasks (streaming, web browsing, emails, using Microsoft Office) will run smoothly on a dual-core processor
  • Processors with ‘Turbo Boost’ can deal with complex tasks for a short period of time
  • The majority of computers come with two processor options, AMD and Intel

Tips for gamers or video editors

If you’re  looking for a new gaming laptop then the graphics card, RAM and hard drive (and/or solid state drive) should be the most influential features in your decision.

If you’ll be doing a lot of demanding video editing, then the processor you choose will be just as important as the other features. Check the type of processor your video editing software works best with. A graphics card will also be important and again, the video editing software you use may influence what you go for. Graphics cards can accelerate rendering times and playback.

Disc drives

Few laptops come with storage disc drives, particularly ultra mobile models such as the MacBook Air and Microsoft Surface Laptop. However, some still do and may feature a:

Digital Video Disc (DVD) drive

  • Reads DVDs as well as audio CDs and software CD-ROMs
  • Stores up to 4.7 gigabytes of data
  • DVDs can store much more data than a CD-ROM
  • The majority of DVD drives will also write to DVD-R, DVD-RW, CD-R and CD-RW discs

DVD-RW drive

  • 'Writes to' (records onto) a blank DVD, as well as reading it
  • Useful for burning home movies to DVD

BD (Blu-Ray) drive

  • Reads Blu-Ray discs containing high definition video or data
  • Usually reads video or data DVDs as well as audio or data CDs
  • Has a storage capacity of up to 50 gigabytes (GB) of information
  • Many BD drives can also write (record) to Blu-ray, DVD or CD media

If you are buying a laptop without a DVD drive, you can buy an external DVD writer to read and write your discs.


Matt or gloss?

  • Easier to view in bright light and easier
    to clean

  • Helps to reduce eye strain if you’re
    working for long periods

  • Better for colour accuracy

  • Provides vivid colours, higher contrast
    and deeper blacks

  • Great for gaming and watching films

  • Better for use where there is less
    light or glare

Internet access
  • Connect to your home network (using a wireless router) or public Wi-Fi hotspots
  • Some laptops include slot for a mobile SIM card
  • Connect to wireless phone networks using 3G or HSPA+ data signals
  • Some larger or gaming laptops feature Ethernet ports
  • These give you the option to connect to your router via a cable for a faster, more secure connection - although this also depends on the cable you use
Sound cards & speakers
  • A sound card generates the computer's audio capability
  • It produces all the sounds required for audio tracks, games and so on
  • Built in to laptops and tablets
  • For the best experience purchase a set of external loudspeakers or connect to your home speakers using bluetooth or NFC
