| + | Machine-to-Machine (M2M) refers to technologies that allow both wireless and wired systems to communicate with other devices of the same ability. M2M uses a device (such as a sensor or meter) to capture an event (such as temperature, inventory level, etc.), which is relayed through a network (wireless, wired or hybrid) to an application (software program), that translates the captured event into meaningful information (for example, items need to be restocked). | ||

Denial of Service Attack
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers
Grid Computing
Like Server Clusters but more loosely couples, hetrogenoeus and distributed. The World Community Grid is a good example of millions of PC's processing power devoted to computing calucations
M2M
Machine-to-Machine (M2M) refers to technologies that allow both wireless and wired systems to communicate with other devices of the same ability. M2M uses a device (such as a sensor or meter) to capture an event (such as temperature, inventory level, etc.), which is relayed through a network (wireless, wired or hybrid) to an application (software program), that translates the captured event into meaningful information (for example, items need to be restocked).
MAC Address
A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used for numerous network technologies including Ethernet. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address.
MX Record
A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol
NFC
Near Field Communication devices are shortwave wireless devices that can exchnage information at short distances. For instance automated payment, transfer of data with other NFC devices, unlocking doors, etc. This is similar to Bluetooth except that data transfer is over very much smaller distances.
.NET
The .NET Framework is a software framework for Microsoft Windows operating systems. It includes a large library, and it supports several programming languages which allows language interoperability (each language can use code written in other languages). The .NET library is available to all the programming languages that .NET supports http://www.microsoft.com/net/
NOC
Network operation center. Usually hosted data centers.
PCL
Printer Command Language is a defacto standard developed by HP. In general terms the the higher the PCL number i.e. 6 the greater the number of printing options it has in terms of font rendering, WYSIWYG printing outputs etc.
Telnet
Telnet is a computer protocol like http and ftp. Telnet stands for 'telecommunications network', and was built to be form of remote control to manage mainframe computers from distant terminals. Telnet has evolved into a new modern version of remote control called 'SSH', that network administrators use today to manage linux and unix computers from a distance. Another kind of Telnet client is PuTTY
UNC
Universal Naming Convention is used by Microsoft to designate its directory path names. In most cases this is double backslash computer name backslash directory name or file name and so on. i.e.\\computer\directory\file. Compare with Unix or the internet that uses forward slash
XML
XML is a machine readable code similar and simpler than HTML. RSS, SOAP ATOM are all XML based formats. EDI messages are sent via XML to customers and Syncada, etc
