Business computers may require additional memory, professional operating-system features, multiple displays or stronger security and networking capabilities. High-performance computers may include faster processors, dedicated graphics cards, additional RAM and larger SSD storage for demanding workloads.

Understanding Windows Editions

Many desktop computers are supplied with Microsoft Windows. Windows is available in different editions designed for home, professional and business environments. The exact operating system supplied should always be checked in the individual computer specifications.

Windows for Home Computers

Home editions of Windows are designed for everyday computing, internet access, entertainment, productivity applications and general personal use. They provide the core features required by most home users.

Windows for Business and Professional Computers

Professional editions can include additional security, management, networking and remote-access features. These versions are commonly selected for business environments, professional users and organisations that require additional administration capabilities.

Important Computer Specifications to Compare

Computer specifications determine how quickly a system performs, which software it can run and how suitable it will be for future requirements. The following components are among the most important specifications to compare when buying a desktop computer.

Processor - CPU

The processor, also known as the CPU or Central Processing Unit, performs the primary calculations required by the operating system and applications. Processor performance can affect system responsiveness, multitasking, productivity applications, gaming and demanding professional software.

A computer intended for basic office applications may require considerably less processing power than a workstation, gaming PC or computer used for video production and 3D rendering.

System Memory - RAM

RAM, or Random Access Memory, provides temporary working memory for Windows and running applications. Having sufficient RAM helps a computer run multiple programs and browser tabs smoothly and can improve performance when working with larger files or demanding software.

The amount of memory required depends on the operating system, applications and workload. Computers used for professional software, virtual machines, content creation and intensive multitasking may benefit from additional RAM.

Computer Storage - SSD and HDD

Computer storage is used for Windows, software, documents, photographs, videos and other files. Modern computers frequently use a Solid State Drive, or SSD, because SSD storage provides much faster access to data than traditional mechanical hard disk drives.

An SSD can improve Windows startup times, application loading and general responsiveness. Larger-capacity drives provide additional space for programs and files, while some systems combine an SSD for performance with additional storage for larger data collections.

Graphics - Integrated or Dedicated

Computer graphics may be integrated into the processor or provided by a dedicated graphics card. Integrated graphics are suitable for many office, internet, multimedia and everyday computing applications.

A dedicated graphics card, commonly referred to as a GPU, may be required for gaming, 3D modelling, engineering applications, video production, artificial intelligence workloads and other graphics-intensive software. Always check the requirements of the applications you intend to use.

Computer Case and Expansion

The computer case protects the internal hardware and assists with cooling and airflow. Case size can also determine which upgrades and expansion cards can be installed in future.

Compact desktop computers save desk space, while larger tower systems generally provide more room for storage drives, graphics cards, memory upgrades and additional expansion hardware.

Power Supply - PSU

The PSU, or Power Supply Unit, converts mains electricity into the regulated power required by the computer components. A suitable power supply is important for system stability and reliability.

Standard office computers normally have moderate power requirements, while gaming computers and high-performance workstations with dedicated graphics hardware can require higher-capacity power supplies.

Computers for Home Use

Home computers can be used for web browsing, email, online banking, video streaming, photographs, schoolwork, productivity applications and general entertainment. A well-balanced system with sufficient RAM and SSD storage can provide responsive everyday performance without requiring specialised hardware.

Computers for Business and Office Use

Business desktop computers are designed for everyday office applications such as accounting, email, web-based services, spreadsheets, document processing, video conferencing and business software. Depending on the organisation, important considerations can include reliability, warranty support, network connectivity, multiple-monitor support and professional Windows features.

High-Performance and Gaming Computers

Gaming PCs and high-performance desktop computers use more powerful hardware for demanding software and workloads. These systems may include faster multi-core processors, additional RAM, high-speed SSD storage, dedicated graphics cards and higher-capacity power supplies.

The hardware required varies considerably between applications and games, so buyers should compare the recommended system requirements of the software they intend to run before selecting a computer.

Why Choose a Pre-Built Computer?

Pre-built computers provide a straightforward way to buy a complete PC without having to research and assemble every individual component. They can be especially convenient for buyers who prefer a tested configuration with straightforward installation and support.

• Complete computer supplied as a compatible system.
