Generally describes the size and layout of a system. Make certain that any dimensional limitations are considered before making a selection. In addition, special system requirements and the number of internal components required have a critical role in the proper selection.
The Central Processing Unit is equivalent to the brain of a computer system. It is responsible for managing virtually all calculations and orchestrating system activities. The size and speed of the CPU will determine the overall efficiency of the entire system. Be aware that other system components, operating systems and software can be limiting factors.
A cool running CPU will operate at peak performance. An overheated CPU can cause system failures and permanent damage including the loss of data.
The Motherboard is equivalent to the body of the system. Every single system device is attached to and interacts with the Motherboard. Not only does the Motherboard provide for a foundation, but it also contains the Basic Input Output System that is required for booting. Intel socket types will only accept Intel CPU's. The same is true for AMD CPU's.
This is the part of the system that you physically see from the outside, liken to your skin. Similarly, what is contained within the case can be limited by the type of chassis selected. In addition, different applications, necessitate the use of different chassis due to environmental conditions and weight restrictions.
Generally this is where the Operating System, Program and Data Files are stored. When multiple Hard Drives are used, the functionality of each can be segmented. Solid State drives are generally considered more reliable as there are no moving parts. Unless specifically stated all Hard Disk Drives quoted will be SATA, 6.0GBS, 64MB Cache and 7200RPM's.
Multiple Hard Drives are generally utilized on new systems when specific RAID Schemas are desired. In the event, RAID is desired the selection of Secondary Hard Drives must meet critical criteria. While not absolutely essential the best practice is to utilize identical Hard Drives.
When selecting multiple Hard Drives, please be certain that the required RAID Schema is specifically stated. Keep in mind that multiple Hard Drives generate more heat. Similar to the CPU, heat can adversely effect the performance of your system and may result in irreparable damage and the loss of all data.
Dependent on the Motherboard selected, a graphics card may not be necessary. This is especially true when on-board graphics exceed system requirements. Graphics cards are useful for digital graphics applications and are most popular with gamers. Alternatively, the utilization of a graphics card does reduce the overall Motherboard load.
The primary purpose of a second GPU is to augment an exisiting primary GPU. Specifically, for a new system, it is probably best to purchase a single GPU with the memory type and capacity required. In addition, it is necessary to be certain that both GPU's and the Motherboard are Crossfire or SLI ready, to achieve the deired results.
Random Access Memory is used when computer data is not stored permanently on a Hard Drive. As a comparison, newspapers can be divided into articles you clip and file and those you simply read over and throw away. 32 Bit Systems will recognize up to 4GB of RAM while 64 Bit Systems recognize significantly more. RAM speed can be similarly correlated to reading speed.
PSU selection is critical to ensure system components will function properly in unison. Fixed cable units limit the number of devices that can be connected. Modular cables provide for greater flexibility. The service life of a PSU is the estimated Mean Time Between Failures. The efficiency rating is a comparison between stated output energy versus energy input.
These internally mounted and externally accessible devices have many purposes including but not limited to: loading Operating Systems and Software. While many modern applications can be downloaded from the internet, maintaining optical disks can be more convenient and sometimes the only option for recovering from a system failure.
Including a secondary optical drive is recommended when there is a necessity to duplicate (burn) other optical media. While it may be feasible to store optical data to a Hard Drive and then burn it to an optical disk, it is not the most effective method for high volume applications. Blu Ray optical drives provide greater storage capacity.
In simple terms the Operating System coordinates activities between the human operator and all system devices. In the event that a system with "NO OPERATING SYSTEM" is selected, no Warranty or Tier I Technical support will be provided. Furthermore, the buyer is entirely responsible for component and system compatability issues.
Based on the purpose of the system, many additional interface devices are available. These options are customer specific and must be addressed as part of the overall system design and review process to avoid redundancy and proper overall system sizing of each component.
As a customer convenience, total turnkey systems with peripherals are offered. To ensure complete customer satisfaction, please provide as much detail as possible pertaining to any desired devices. Alternatively, recommendations can be provided based on system configurations as requested.
