Content-control Software
An Internet filter is software that restricts or controls the content an Internet user is capable to access, especially when utilized to restrict material delivered over the Internet via the Web, Email, or other means. Content-control software determines what content will be available or be blocked. Such restrictions can be applied at various levels: a government can attempt to apply them nationwide (see Internet censorship), or they can, for example, be applied by an Internet service provider to its clients, by an employer to its personnel, by a school to its students, by a library to its visitors, by a parent to a child's computer, or by an individual users to their own computers. The motive is often to prevent access to content which the computer's owner(s) or other authorities may consider objectionable. When imposed without the consent of the user, content control can be characterised as a form of internet censorship. Some content-control software includes time control func ...

Ad Filtering
Ad blocking or ad filtering is a software capability for blocking or altering online advertising in a web browser, an application or a network. This may be done using browser extensions or other methods. Technologies and native countermeasures Online advertising exists in a variety of forms, including web banners, pictures, animations, embedded audio and video, text, or pop-up windows, and can even employ audio and video autoplay. Many browsers offer some ways to remove or alter advertisements: either by targeting technologies that are used to deliver ads (such as embedded content delivered through browser plug-ins or via HTML5), targeting URLs that are the source of ads, or targeting behaviors characteristic to ads (such as the use of HTML5 AutoPlay of both audio and video). Prevalence Use of mobile and desktop ad blocking software designed to remove traditional advertising grew by 41% worldwide and by 48% in the U.S. between Q2 2014 and Q2 2015. As of Q2 2015, 45 million A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprietary Software
Proprietary software is software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors ...

Commercial Software
Commercial software, or seldom payware, is a computer software that is produced for sale or that serves commercial purposes. Commercial software can be proprietary software or free and open-source software. Background and challenge While software creation by programming is a time and labor-intensive process, comparable to the creation of physical goods, the reproduction, duplication and sharing of software as digital goods is in comparison disproportionately easy. No special machines or expensive additional resources are required, unlike almost all physical goods and products. Once a software is created it can be copied in infinite numbers, for almost zero cost, by anyone. This made commercialization of software for the mass market in the beginning of the computing era impossible. Unlike hardware, it was not seen as trade-able and commercialize-able good. Software was plainly shared for free (hacker culture) or distributed bundled with sold hardware, as part of the service t ...

Children's Internet Protection Act
The Children's Internet Protection Act (CIPA) is one of a number of bills that the United States Congress proposed to limit children's exposure to pornography and explicit content online. Background Both of Congress's earlier attempts at restricting indecent Internet content, the Communications Decency Act and the Child Online Protection Act, were held to be unconstitutional by the U.S. Supreme Court on First Amendment grounds. CIPA represented a change in strategy by Congress. While the federal government had no means of directly controlling local school and library boards, many schools and libraries took advantage of Universal Service Fund (USF) discounts derived from universal service fees paid by users in order to purchase eligible telecom services and Internet access. In passing CIPA, Congress required libraries and K-12 schools using these E-Rate discounts on Internet access and internal connections to purchase and use a "technology protection measure" on every computer ...

Deep Content Inspection
Deep content inspection (DCI) is a form of network filtering that examines an entire file or MIME object as it passes an inspection point, searching for viruses, spam, data loss, key words or other content level criteria. Deep Content Inspection is considered the evolution of Deep Packet Inspection with the ability to look at what the actual content contains instead of focusing on individual or multiple packets. Deep Content Inspection allows services to keep track of content across multiple packets so that the signatures they may be searching for can cross packet boundaries and yet they will still be found. An exhaustive form of network traffic inspection in which Internet traffic is examined across all the seven OSI ISO layers, and most importantly, the application layer. Background Traditional inspection technologies are unable to keep up with the recent outbreaks of widespread attacks. Unlike shallow inspection methods such as Deep Packet Inspection (DPI), where only the da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avira
Avira Operations GmbH is a German multinational computer security software company mainly known for their Avira Free Security antivirus software. Avira was founded in 2006, but the antivirus application has been under active development since 1986, through its predecessor company H+BEDV Datentechnik GmbH. Since 2021, Avira is owned by American software company NortonLifeLock (now Gen Digital), after being previously owned by investment firm Investcorp. The company also has offices in the United States, China, Romania, and Japan. Technology Virus definition Avira periodically "cleans out" its virus definition files, replacing specific signatures with generic ones for a general increase in performance and scanning speed. A 15 MB database clean-out was made on 27 October 2008, causing problems to the users of the Free edition because of its large size and Avira's slow Free edition servers. Avira responded by reducing the size of the individual update files, delivering les ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Virtual Appliance
A virtual appliance is a pre-configured virtual machine image, ready to run on a hypervisor; virtual appliances are a subset of the broader class of software appliances. Installation of a software appliance on a virtual machine and packaging that into an image creates a virtual appliance. Like software appliances, virtual appliances are intended to eliminate the installation, configuration and maintenance costs associated with running complex stacks of software. A virtual appliance is not a complete virtual machine platform, but rather a software image containing a software stack designed to run on a virtual machine platform which may be a Type 1 or Type 2 hypervisor. Like a physical computer, a hypervisor is merely a platform for running an operating system environment and does not provide application software itself. Many virtual appliances provide a Web page user interface to permit their configuration. A virtual appliance is usually built to host a single application; it the ...

Raspberry Pi
Raspberry Pi () is a series of small single-board computers (SBCs) developed in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. The Raspberry Pi project originally leaned towards the promotion of teaching basic computer science in schools and in developing countries. The original model became more popular than anticipated, selling outside its target market for uses such as robotics. It is widely used in many areas, such as for weather monitoring, because of its low cost, modularity, and open design. It is typically used by computer and electronic hobbyists, due to its adoption of the HDMI and USB standards. After the release of the second board type, the Raspberry Pi Foundation set up a new entity, named Raspberry Pi Trading, and installed Eben Upton as CEO, with the responsibility of developing technology. The Foundation was rededicated as an educational charity for promoting the teaching of basic computer science in schools and developing co ...
