Computer technology - Essay Example Computer systems consist of both software and hardware. The hardware components are tangible components of the system: main memory, CPU, peripherals such as monitor, video display etc (Gookin 2006). Software part is the set of instructions that define what the actions of the computer hardware (Alagar and Peryasammy 2011). Typically a computer requires both the system software Minimum user requirements Fred, Barry and Jane need a Single PC for their gaming needs. Frankly, there are no many options for a PC with the minimum requirements they desire that can go for the price in their budget estimate of 350. For a gaming PC no existing integrated graphics acceleration cards can handle the processing requirements of the game. In this case a graphics processor that is dedicated will still be required. OS: Windows Vista or Windows 7 Processor: Core 2 Duo 2.4 GHz or Althon X2 2.7 GHz RAM: 2GB Graphic card: DirectX 10 or 11 compatible Nvidia or AMD ATI card, ATI Radeon 3870 or higher, Nvidia GeForce 8800 GT or higher. Graphics card memory: 512 MB Sound card: DirectX compatible sound card Hard drive: 15 GB for disc version or 10 GB for digital version Fig. 1 Complete desktop computer The retailer has the option of making a choice between several brands, manufacturers of computers; Dell, Hewlett Packard and IBM. In my assessment I would recommend a machine that is high performing with the functionality that can well fit the gaming requirements. Since the budget constraints the selections, the best option is to go for the components that are most important in supporting gaming requirements. The computer features most essential for a gaming machine are; processor, graphics card, internal memory and hard disk capacity. Compromising on other desired features such as sound will not harm the game and the advantage will be the cost cuts. Justification Quad-Core Processor Though lesser processors such as dual-core are cheaper and within the budget, the ability of a quad core to s upport a larger number of tasks at the same time is a must for serious gaming. This is a good processor will help the computers to run effectively. The processor is the brain of the computer and controls most of the work done by the PC. For gaming requirements, multimedia multitasking, for example video recording while browsing will give a more pleasant experience. Processors are generally defined by their speed - in megahertz (MHz) or in gigahertz (GHz) - and it relates to the number of operations they can perform per second. The higher the value, the faster the PC will perform and the more expensive it generally is. I will recommend the Quad-Core AMD Opteronâ„ ¢ Processor with Direct Connect Architecture are designed to deliver industry leading power efficiency, optimal virtualization, outstanding performance, and low TCO - all within a consistent footprint and thermal envelopes. Fig. 2 Central processing unit AMD Phenomâ„ ¢ X4 Quad-Core Processors is a true quad-core perfor mance for the way gaming multi-task today, and for the next-generation applications that will be needed in the near future. Stable commercial AMD Phenomâ„ ¢ X4 quad-core processors offer industry-leading platform stability and longevity, investment protection, and the exceptional performance you expect from AMD. In addition, the processor comes with unique features for energy efficiency ‘AMD’ (2011). Random Access Memory (RAM) The computers will need about 4 gigabytes of memory so that they can run
