ATA/PATA/ATAPI/IDE connectors were standards created in 1986 to connect storage devices like hard disks inside PCs. There were 34-pin, 40-pin, and 80-pin ATA cable variants, with the 80-pin version also called Ultra DMA. Cable connectors were color coded with blue for the motherboard, gray for slave drives, and black for master drives. SCSI was an alternative interface introduced in 1979 and used for RAID, using internal ribbon cables with 68-pin or 50-pin connectors or external shielded cables. SATA was created in 2003 to replace PATA, offering 1.5-3 Gbit/s serial speeds to eventually replace the older PATA/IDE

Braids, Cables, and Cells I: An Interesting Intersection of Mathematics, Comp...
The mathematical study of braids combines aspects of topology and group theory to study mathematical representations of one-dimensional strands in three-dimensional space. These strands are also sometimes viewed as representing the movement through a time dimension of points in two-dimensional space. On the other hand, the study of cellular automata usually involves a one- or two-dimensional grid of cells which evolve through a time dimension according to specified rules. This time dimension is often represented as an extra spacial dimension.
Therefore, it seems reasonable to ask whether rules for cellular automata can be written in order to produce depictions of braids. The ideas of representing both strands in space and cellular automata have also been explored in many artistic media, including drawing, sculpture, knitting, crochet, and macramé, and we will touch on some of these.

Cables in Computer Networks
There are several types of cables used in networks. Twisted pair cable is used for home and corporate Ethernet networks and cancels out electromagnetic interference. Fibre optic cable has the highest bandwidth and can transmit data over long distances but is expensive. Coaxial cable was mainly used for TV but can now be used for high-speed home networking. Patch cables are short cables that connect electronic devices. Ethernet crossover cables directly connect computers without a switch. Power lines were not designed for networking but new technologies allow them to transmit data.
Statistics for fixed points of x ↦ x^x mod p
This document investigates the distribution of fixed points of the self-power map x → xx (mod p). It finds:
1) The distribution of total fixed points is not normal.
2) The counts of fixed points for most orders d are binomially distributed, as predicted by assuming independent x values.
3) However, for small/large orders d, the independence assumption breaks down. Certain x values of specific orders cannot both be fixed points, violating the prediction. The dependencies must be taken into account.

Types of Hard DiskAmity University | FMS - DU | IMT | Stratford University | KKMI International Institute | AIMA | DTU
The document discusses four main types of computer hard drives:
1) Parallel ATA (PATA) drives were the original type and used parallel signaling.
2) Serial ATA (SATA) drives transfer data faster using serial signaling and have thinner, more flexible cables.
3) Small Computer System Interface (SCSI) drives are faster, more reliable, and better for large data storage and movement.
4) Solid state drives (SSD) have no moving parts, provide faster access, are more durable and shock resistant, and use less power than traditional hard drives.Direct Attached Storage - Information Storage and Management.pptx

Parts of a Computer: Cables
- 1. CABLES
- 2. ATA / PATA / ATAPI /IDE connectors • Advanced Technology Attachment (ATA) is a standard interface for connecting storage devices such as hard disks and CD-ROM drives inside personal computers. • Many synonyms and near-synonyms for ATA exist, including abbreviations such as IDE and ATAPI • original ATA was retroactively renamed Parallel ATA (PATA). • Created 1986 by western digital. • Speed: 16 MB/s originally later 33,66,100 and 133 MB/s
- 3. THE 34 PIN ATA CABLE
- 4. THE 40 PINS ATA CABLE
- 5. THE 80 PINS ATA CABLE
- 6. THE 80 PINS ATA CABLE IS ALSO CALLED Ultra DMA IDE/ATA interface cable
- 7. COLOR CODES ON 80 PINS ATA CABLE Color coding of the connectors is used to make it easier to determine which connector goes with each device: • Blue: The blue connector attaches to the host (motherboard or controller). • Gray: The gray connector is in the middle of the cable, and goes to any slave (device 1) drive if present on the channel. • Black: The black connector is at the opposite end from the host connector and goes to the master drive (device 0), or a single drive if only one is used.
- 8. SCSI cable • Widely used for RAID. • SCSI is based on "SASI", the "Shugart Associates System Interface", introduced by that company in 1979. • Internal SCSI cables are usually ribbon cables that have multiple 68 pin or 50 pin connectors. External cables are shielded and only have connectors on the ends. • Speed: 5 mb/s up to 640 mb/s.
- 9. SCSI cable n’ Card
- 10. SCSI in Action
- 11. SATA • It was designed as a successor to the legacy Advanced Technology Attachment standard (ATA), and is expected to eventually replace the older technology (retroactively renamed Parallel ATA or PATA) • Created 2003. • Speed: 1.5 Gbit/s, 3.0 Gbit/s • Style: serial SCSI Bcurrently offers transfer rates higher than SATA, but is a more complex bus usually resulting in higher manufacturing cost.
