Q

What are three SSD communications interfaces?

A

NVMe, SATA, PCIe

NVMe - non-volate Memory Express, is a device specification introduced by Intel in 2007. It standardizes the way that non-volatile memory devices, such as SSDs, can connect to a computer’s PCI Express (PCIe) bus.

Traditionally, SSDs are connected to the computer using a disk drive interface, such as SATA. However, SATA was designed for older data storage devices, such as HDDs (hard disk drives), and its data transfer speed is limited. Beginning in about 2005, when SSDs first became popular with consumers, the fastest SSDs were reading data quicker than SATA could transfer it. Manufacturers began producing SSDs that could be installed in a PCIe slot, but their interfaces varied widely. The NVMe standard allows any of these devices to be attached to a computer without requiring separate, and possibly conflicting, operating system device drivers.

Traditionally, SSDs are connected to the computer using a disk drive interface, such as SATA. However, SATA was designed for older data storage devices, such as HDDs (hard disk drives), and its data transfer speed is limited. Beginning in about 2005, when SSDs first became popular with consumers, the fastest SSDs were reading data quicker than SATA could transfer it. Manufacturers began producing SSDs that could be installed in a PCIe slot, but their interfaces varied widely. The NVMe standard allows any of these devices to be attached to a computer without requiring separate, and possibly conflicting, operating system device drivers.

SATA - Short for serial AT attachment, SATA 1.0 was first released in August 2001 and is a replacement for the parallel ATA interface used in IBM compatible computers. SerialATA can deliver 1.5 Gbps (approximately 187 MBps) of performance to each drive within a disk array. It is backward-compatible with ATA and ATAPI devices, and offers a thin, small cable solution, as seen in the “SATA Data Cable” picture. This cable helps makes cable routing easier and offers better airflow in the computer compared to the earlier ribbon cables used with ATA drives.

SATA also supports external drives through External SATA more commonly known as eSATA. eSATA offers many more advantages compared to other solutions. For example, it is hot-swappable, supports faster transfer speeds with no bottleneck issues like USB and FireWire, and supports disk drive technologies (e.g., S.M.A.R.T.).

However, eSATA does have some disadvantages, such as not distributing power through the cable like USB, which means drives require an external power source. The eSATA cable also supports a maximum length of up to 2 meters. Because of these disadvantages don’t plan on eSATA becoming the only external solution for computers.

PCie - Originally known as 3rd Generation I/O (3GIO), PCI Express, or PCIe, was approved in July 2002 as a serial computer expansion bus standard. PCI Express was designed as a high-speed replacement for the aging PCI and AGP standards and is available in different formats. The data transmitted over PCI Express is sent over wires (called lanes) in full duplex mode (both directions at the same time). Each lane can transfer speeds around 250 MB/s and each slot can be scaled from 1 to 32 lanes. With 16 lanes, PCI Express supports a bandwidth of up to 4,000 MB/s.

Q

In order to communicate on a network, TCP/IP hosts must have a unique _____ and valid _______.

TCP - Transmission Control Protocol, TCP is a standard that dictates how to establish and maintain a connection through which two programs may exchange data. Invented in 1978 and driven by Bob Kahn and Vint Cerf, TCP is a core component in the TCP/IP protocol, which dictates how information is sent over the Internet.

The IP (Internet Protocol) is the fundamental protocol for communications on the Internet. It specifies the way information is packetized, addressed, transferred, routed, and received by networked devices.

A

IP address, subnet mask

Subnet mask - a subnet mask is data used for bitwise operations on a network of IP addresses that is divided into two or more groups. This process, known as subnetting, divides an IP network into blocks of logical addresses. Subnetting can improve security and help to balance overall network traffic.

A common example of a subnet mask for class C IP addresses is 255.255.255.0, the default subnet mask for many computers and network routers. When applied to subnet, a subnet mask shows the routing prefix.
