Key Specs
- Processor Model: Intel Xeon (Your computer's processor is like its brain. Working in combination with system memory, the power of the processor determines the complexity of software you can run, how many programs you can have open at the same time, and how fast those programs will run. Most computers feature an AMD, Intel or Snapdragon processor.)
- System Memory (RAM): 4 gigabytes (Random-access memory (RAM) is a computing device's short-term data storage, which allows active information to be accessed quickly. The size and type of RAM determines how efficiently the device can handle large amounts of information at one time. For example, gaming or video editing requires more RAM for optimal performance.)

Most computers feature an AMD, Intel or Snapdragon processor.)
Storage
- Hard Drive Capacity: 1024 gigabytes (The amount of data that can be stored on the device's mechanical hard drive. Hard disk drives (HDDs) typically have larger capacities than solid state drives (SSDs) but may have slower speeds.)
Memory
- System Memory (RAM): 4 gigabytes (Random-access memory (RAM) is a computing device's short-term data storage, which allows active information to be accessed quickly. The size and type of RAM determines how efficiently the device can handle large amounts of information at one time. For example, gaming or video editing requires more RAM for optimal performance.)
- Type of Memory (RAM): DDR3 SDRAM (Each type of RAM delivers a different level of speed, bandwidth, energy efficiency and performance.)
Compatibility
- Operating System: Windows 10 (The operating system manages all software and hardware, including files, memory and connected devices. Most importantly, it lets you interact with your device and your programs in a visual way; otherwise, you'd be typing computer code to get anything done.)
- Operating System Architecture: 64-bit (An operating system (OS) manages computer hardware, software resources, and programs in conjunction with the system's processor. 64-bit operating systems can handle more data at once than 32-bit systems, resulting in faster speeds, more effiency, and overall improved performance.)
