      Deciding on Minimum Hardware Requirements

      The company you work for has decided that everyone will have their own laptop running Windows 10. You need to decide on the new computers’ specifications for processor, memory, and disk space.

      The first step is to determine which applications will be used. Typically, most users will work with an email program, a word processor, a spreadsheet application, presentation software, and maybe a drawing or graphics program. Additionally, an antivirus application will probably be used. Under these demands, a 1 GHz Celeron processor and 1 GB of RAM will make for a very slow-running machine. So for this usage, you can assume that the minimum baseline configuration would be higher than a 1 GHz processor with at least 2 GB of RAM.

      Based on your choice of baseline configuration, you should then fit a test computer with the applications that will be used on it and test the configuration in a lab environment simulating normal use. This will give you an idea of whether the RAM and processor calculations you have made for your environment are going to provide a suitable response.

      Today’s disk drives have become capable of much larger capacity while dropping drastically in price. So for disk space, the rule of thumb is to buy whatever is the current standard. At the time this book was written, 500 GB drives were commonplace, which is sufficient for most users. If users plan to store substantial graphics or video files, you may need to consider buying larger-than-standard drives.

      Also consider what the business requirements will be over the next 12 to 18 months. If you will be implementing applications that are memory or processor intensive, you may want to spec out the computers with hardware sufficient to support upcoming needs to avoid costly upgrades in the near future.

      ■ 64 MB is required for a single monitor at a resolution of 1,310,720 pixels or less, which is equivalent to a 1280×1024 resolution.

      ■ 128 MB is required for a single monitor at a resolution of 2,304,000 pixels or less, which is equivalent to a 1920×1200 resolution.

      ■ 256 MB is required for a single monitor at a resolution larger than 2,304,000 pixels.

      Measurement Used for Disk Space and Memory

      Hard disks are commonly rated by capacity. The following measurements are used for disk space and memory capacity:

      ■ 1 MB (megabyte) = 1,024 KB (kilobytes)

      ■ 1 GB (gigabyte) = 1,024 MB

      ■ 1 TB (terabyte) = 1,024 GB

      ■ 1 PB (petabyte) = 1,024 TB

      ■ 1 EB (exabyte) = 1,024 PB
