1.
Dedicated block-based storage, leveraging a high-speed architecture that interconnects and delivers shared pools of storage devices to multiple servers. A SAN makes its data act as if it were locally attached.
2.
A server that connects to the shared storage device. They run initiator software that connects to and communicates with the SAN target.
3.
All SAN storage devices are called targets.
4.
A protocol used in TCP/IP networks' data storage solutions. The advantage is the speed of data flow.
5.
This is an approach to network management that lets you centrally control (or program) a network intelligently using a software application. This helps make the management of the entire network consistent regardless of the underlying network technology.
6.
This is a protocol optimized for the transmission of voice data (telephone calls) through a packet-switched IP network. VoIP routes phone calls through an IP network, including the internet. VoIP solutions can integrate with the public switched telephone
7.
This converts voice and fax calls between the PSTN and your IP network in real time.
8.
In VoIP, audio is converted from an analog signal to digital data through a technique called sampling.
9.
A special algorithm that compresses VoIP data to reduce bandwidth consumption. On the receiving end, the same algorithm is used to decompress the data.
10.
This is a measure of delay as a packet of data travels from one point to another. Too much latency causes VoIP callers to talk over each other.
11.
This is a variation in the delay or latency of received packets. Latency going up and down during a call can cause unusual sound effects (minor pauses, jumps, choppiness).
12.
Appliances that plug directly into your network and provide a wide variety of communication services, such as voice, voicemail, instant messaging, and faxing.
13.
This is the ability to install and run multiple operating systems simultaneously on a single physical machine.
14.
This is a thin layer of software that resides between the virtual operating system(s) and the hardware. A hypervisor allows virtual machines to interact with the hardware without going through the host operating system. A hypervisor also manages access to
15.
This is a software implementation of a computer that executes programs like a physical machine. The virtual machine appears to be a self-contained and autonomous system, but it runs on a host computer and functions through a hypervisor.
16.
This is a file created within the host operating system that simulates a hard disk for the virtual machine.
17.
In this, the hardware is not virtualized. All of the guest operating systems running on the hypervisor directly access various hardware resources on the physical device. Components are not virtual. The guest operating systems run in isolated domains on th
18.
In this, only some of the components of the virtual machine are virtualized. The guest operating systems use some virtual components and some real physical hardware components on the actual device where the hypervisor is running. Operating systems or appl
19.
In this, the virtual machine completely simulates a real physical host. This allows most operating systems and applications to run within the virtual machine without being modified in any way.
20.
A software version of a physical network adapter. It is used in a virtual machine. Virtual network interfaces can connect to either a physical or virtual network.
21.
A switch that allows one virtual machine to communicate with another in much the same way that a physical switch allows physical hosts to communicate with each other.
22.
A subnetwork collection of devices that may be on separate physical LANs. Most virtual switch implementations support VLANs. You can define VLANs within the virtual switch and associate specific hosts with a specific VLAN.Because virtual h
23.
A software-based routing framework that allows the host machine to perform as a typical hardware router over a local area network.
24.
A firewall within the hypervisor. It lets you monitor and filter traffic on the virtual network as it flows between virtual machines. It is also seen in cloud environments as well as defense in depth tools.
25.
This is a combination of software, data access, computation, and storage services provided to clients through the internet. The term cloud is a metaphor for the internet based on the basic cloud drawing used to represent the telephone network
26.
Cloud-based computing resources such as platforms, applications, and storage are made available to the general public by a cloud service provider (such as Google's Gmail). A public cloud can be accessed by anyone, although some may require a fee.
27.
This deployment model provides resources to a single organization. Private clouds can be hosted internally, behind a firewall. The majority are hosted by the company, while some maybe assisted by a cloud service provider (CSP).
28.
This is a model that offers free applications to the public. Many times, these are segmented into business verticals. Social Community Clouds would include Facebook, Reddit and Twitter for example. These Community Clouds just require username and password
29.
This model is a combination of public (sometimes multiple) and, private clouds that are leveraged for certain kinds of apps.
30.
When multiple public clouds are used by a company because of cost or team preferences. This requires extra vigilance in managing the use of multiple public cloud platforms.
31.
This service model delivers infrastructure to the client, such as processing, storage, networks, and virtualized environments. The client deploys and runs software without purchasing servers, data center space, or network equipment. The client is still re
32.
This service model delivers everything a developer needs to build an application. The deployment comes without the cost and complexity of buying and managing the underlying hardware and software layers. It also provides the services that an OS normally pr
33.
This service model delivers software applications to the client either over the internet or on a local area network. This is by far the most used model.
34.
The internet of things.
35.
A smart speaker that controls smart appliances and performs other actions through voice commands.
36.
A protocol used by wireless mesh networks for communication with smart devices.
37.
An IoT standards-based protocol similar to Zigbee but simpler and less expensive.
