 6. Hard Drive

Hard Drive - Provided in the format SSD 256GB M.2 (NVMe), which is as follows
[Drive Type] [Capacity] [Dimension] / [Interface]

Drive Type
1. SSD is a fast and durable drive built from memory chip circuits,
2. HDD is a mechanical drive where data is placed on spinning platters read by a moving head, suspended above the platters. Data is read using electromagnetic forces.
3. SSHD combines the two technologies but is mainly an HDD with frequently used files moved to semiconductor memory. 

Capacity - The capacity of the drive, e.g., 1TB = 1024GB / 1000GB, depending on the manufacturer's labeling, so a 1TB drive has only 931GB  instead of 1024GB because smaller units are rounded: 1GB = 1024MB, 1MB = 1024KB, and manufacturers simplify to 1MB = 1000KB

Dimension - Physical size of the drive
1. 2.5" - dimensions of the drive are 69.85 mm x 100.50 mm, usually using the SATA interface
2. M.2 - dimensions of the drive are 22mm by (30mm / 42mm/ 80mm / 100mm) using the M.2 interface

Interface - Communication standard
SATA - Interface speed is 6Gb/s, providing a maximum bandwidth of up to 600MB/s, depending on the drive
NVMe - Using PCIe lines, the main speed limitation is the drive itself, with throughput up to 2GB/s.

*An SSD that fails often results in permanent data loss due to its operation specifics.
**HDD data is physically written on the platters, and specialized companies can recover data from seriously damaged drives, but it comes at a cost, so always MAKE BACKUP COPIES OF IMPORTANT DATA on another device or in the cloud. 

Additional Hard Drive - Additional built-in hard drive, labels as above.

 7. Screen

Screen Resolution - The number of pixels given as width x height. A pixel is one micro square on the monitor, and the following standards can be distinguished
