Efficient Computer in a Network, serves to allocate data to other computers (see also Client).

SEO

Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic (known as "natural" or "organic" results) rather than direct traffic or paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academic search, news search, and industry-specific vertical search engines.

As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. SEO is performed because a website will receive more visitors from a search engine when websites rank higher on the search engine results page (SERP). These visitors can then potentially be converted into customers.

Shareware

made-up word from “share” and “software”.
In this case "share" means the usage rights on a computer software. Fair sharing of development costs with all purchasers. High quality and fair prices makes authors successful and famous. This is no guarantee for richness, but famosity is helpful for marketing.

Shareware Concept

Everyone has the permission to test the software before purchasing it. Because the price is calculated fair, very much users pay for Shareware and the author gets the same or more money as he has offered his software as regular payware. Most pleased users are fair and do pay for it.

SIM

(Abbr.:) Subscriber Identification Module. The Chip on a phone card for a mobile phone (GSM cellular phone).

SIM Toolkit

(Abbr.:) Subscriber Identification Module-Toolkit. Technology for programming of mobile phones. Requires new SIM-cards with double-sized memory. Therewith the SIM-card can active communicate between mobile phone and cellular network provider (for example: “T-Mobile t-zone”, “Vodafone live”).

SLR (Camera)

Camera with single-lens-reflex technology. The photographer looks direct through the objektiv lens; the picture will be directed from the objektiv through a mirror to a view-finder prism.

Smartphone

(made-up word for a mobile phone with an operating system and PDA-functions like addressbook, calendar, tasks, notice and E-Mail.
A real smart phone allows to add missed functions by installing more suitable applikations (Apps). That is the reason for their big success.

Smartphone Zombie (German abbr.: smombie)

is a pedestrian who walks slowly and without attention to their surroundings because they are focussed upon their smartphone. This is now a significant safety hazard as distracted pedestrians cause accidents. Cities such as Chongqing and Antwerp have introduced special lanes for smartphone users to help direct and manage them.

Texting pedestrians may trip over curbs, walk out in front of cars and bump into other walkers. The field of vision of a smartphone user is estimated to be just 5% of a normal pedestrian's. An app which uses the phone's camera to make it seem transparent can be used to provide some warning of hazards. In Augsburg and Cologne, ground-level traffic lights embedded in the pavement have been introduced so that they are more visible to preoccupied pedestrians. In Seoul, warning signs have been placed on the pavement at dangerous intersections following over a thousand road accidents caused by smartphones in South Korea in 2014.

S/MIME

S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public-key encryption and signing of MIME data. S/MIME is on an IETFstandards track and defined in a number of documents, most importantly RFC 8551. It was originally developed by RSA Data Security, and the original specification used the IETF MIME specification with the de facto industry standard PKCS #7 secure message format. Change control to S/MIME has since been vested in the IETF, and the specification is now layered on Cryptographic Message Syntax (CMS), an IETF specification that is identical in most respects with PKCS #7. S/MIME functionality is built into the majority of modern email software and interoperates between them. Since it is built on CMS, MIME can also hold an advanced digital signature.

SMS

Short Message Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile devices exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.

SMS technology originated from radio telegraphy in radio memo pagers that used standardized phone protocols. These were defined in 1986 as part of the Global System for Mobile Communications (GSM) series of standards. The first SMS message was sent on 3 December 1992, when Neil Papworth, a test engineer for Sema Group, sent "Merry Christmas" to the Orbitel 901 phone of colleague Richard Jarvis. SMS rolled out commercially on many cellular networks that decade and became hugely popular worldwide as a method of text communication. By the end of 2010, SMS was the most widely used data application, with an estimated 3.5 billion active users, or about 80% of all mobile phone subscribers.

The service allows users to send and receive messages of up to 160 characters (when entirely alpha-numeric) to and from GSM mobiles. Although most SMS messages are sent from one mobile phone to another, support for the service has expanded to include other mobile technologies, such as CDMA networks and Digital AMPS.

Software

“Soft Ware”: means ware, which you cannot touch. A program, which is running on a chip. See also “Firmware”.

Source Code

Programming code before compiling (see Compiler). At HTML- or PHP-programming the source code is the finished code, cause it needs no compiling.

Spam

Unwanted E-Mails. Mostly advertising or Malware (see also Email-Spam or Junk-Mail).

SPF

Sender Policy Framework (SPF) is an email authentication method which ensures the sending mail server is authorized to originate mail from the email sender's domain. This authentication only applies to the email sender listed in the "envelope from" field during the initial SMTP connection. If the email is bounced, a message is sent to this address, and for downstream transmission it typically appears in the "Return-Path" header. To authenticate the email address which is actually visible to recipients on the "From:" line, other technologies such as DMARC must be used. Forgery of this address is known as email spoofing, and is often used in phishing and email spam.

The list of authorized sending hosts and IP addresses for a domain is published in the DNS records for that domain. Sender Policy Framework is defined in RFC 7208 dated April 2014 as a "proposed standard".

SSD

(Abbr.:) Solid State Disk. A non-volatile electronic storage medium used in computer technology.

SSL

(Abbr.:) Secure Socket Layer. Ciphering method on protokoll level. Using e.g. for ciphering the transmission between your Browser and the datacentre of your bank. Noticeable with the symbol of a padlock at your Browser. A secure internet address begins with https:// (s like secure). Development since version 3.0 with new name TLS.

SVG

(Abbr.:) Scalable Vector Graphics is the recommended specification of the World Wide Web Consortium ( W3C) to describe 2-dimensional vector graphics. SVG, based on XML, published first in September of 2001.
Some of the most common web browsers can display the majority of the commands. The Internet Explorer needs an extension (plug-in) for that until version 8.
Animations will be supported via SMIL. Manipulations of the SVG-DOM are possible with help of embedded funktions via script languages.
Cause of SVG is a XML-based file format, SVG-files can be edited with a text editor.
