Head Girl And Head Boy
Head boy and head girl are student leadership roles in schools, representing the school's entire student body. They are normally the most senior prefects in the school. The terms are commonly used in the British education system as well as in Australia and private schools throughout the Commonwealth. Some schools use alternative titles such as school captain. Head boys and head girls are usually responsible for representing the school at events, and will make public speeches. They also serve as a role model for students, and may share pupils' ideas with the school's leadership. They may also be expected to lead fellow prefects in their duties. Deputy head boys and girls may also be appointed. Some schools in the UK no longer use the titles of head boy and head girl, and now have a role of "head pupil". See also *Senior Prefect Prefect (from the Latin ''praefectus'', substantive adjectival form of ''praeficere'': "put in front", meaning in charge) is a magisterial title of va ...

Business Incubator
Business incubator is an organization that helps startup companies and individual entrepreneurs to develop their businesses by providing a fullscale range of services starting with management training and office space and ending with venture capital financing. The National Business Incubation Association (NBIA) defines business incubators as a catalyst tool for either regional or national economic development. NBIA categorizes its members' incubators by the following five incubator types: academic institutions; non-profit development corporations; for-profit property development ventures; venture capital firms, and a combination of the above. Business incubators differ from research and technology parks in their dedication to startup and early-stage companies. Research and technology parks, on the other hand, tend to be large-scale projects that house everything from corporate, government, or university labs to very small companies. Most research and technology parks do not o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dollar Sign
The dollar sign, also known as peso sign, is a symbol consisting of a capital " S" crossed with one or two vertical strokes ($ or ), used to indicate the unit of various currencies around the world, including most currencies denominated "peso" and "dollar". The explicitly double-barred sign is called cifrão. The sign is also used in several compound currency symbols, such as the Brazilian real (R$) and the Nicaraguan córdoba (C$). The one- and two-stroke version are often considered mere stylistic (typeface) variants, although in some places and epochs one of them may have been specifically assigned, by law or custom, to a specific currency. The Unicode computer encoding standard defines a single code for both. In most English-speaking countries that use that symbol, it is placed to the left of the amount specified, e.g. "$1", read as "one dollar". History Use for the Spanish American peso in the late 1700s The symbol appears in business correspondence in the 1770s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Rand
The South African rand, or simply the rand, ( sign: R; code: ZAR) is the official currency of the Southern African Common Monetary Area: South Africa, Namibia (alongside the Namibian dollar), Lesotho (alongside the Lesotho loti) and Eswatini (alongside the Swazi lilangeni). It is subdivided into 100 cents (sign: "c"). The South African rand is legal tender in the Common Monetary Area member states of Namibia, Lesotho and Eswatini, with these three countries also having their own national currency (the dollar, the loti and the lilangeni respectively) pegged with the rand at parity and still widely accepted as substitutes. The rand was also legal tender in Botswana until 1976, when the pula replaced the rand at par. Etymology The rand takes its name from the Witwatersrand ("white waters' ridge" in English, ''rand'' being the Dutch and Afrikaans word for 'ridge'), the ridge upon which Johannesburg is built and where most of South Africa's gold deposits were found.

Internet Security
Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet is an inherently insecure channel for information exchange, with high risk of intrusion or fraud, such as phishing, online viruses, trojans, ransomware and worms. Many methods are used to combat these threats, including encryption and ground-up engineering. Threats Malicious software Malicious software comes in many forms, such as viruses, Trojan horses, spyware, and worms. * Malware, a portmanteau of malicious software, is any software used to disrupt computer operation, gather sensitive information, or gain access to private computer systems. Malware is defined by its malicious intent, acting against the requirements of the computer user, and does not include softw ...

Digital Certificate
In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a Key authentication, public key. The certificate includes information about the key, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). If the signature is valid, and the software examining the certificate trusts the issuer, then it can use that key to communicate securely with the certificate's subject. In email encryption, code signing, and Electronic signature, e-signature systems, a certificate's subject is typically a person or organization. However, in Transport Layer Security (TLS) a certificate's subject is typically a computer or other device, though TLS certificates may identify organizations or individuals in addition to their core role in identifying devices. TLS, sometimes called by its older n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thawte Consulting
Thawte Consulting (pronounced "thought") is a certificate authority (CA) for X.509 certificates. Thawte was founded in 1995 by Mark Shuttleworth in South Africa. As of December 30, 2016, its then-parent company, Symantec Group, was collectively the third largest public CA on the Internet with 17.2% market share. History Thawte was originally run from Mark Shuttleworth's parents' garage. Shuttleworth originally aimed to produce a secure server not fettered by the restrictions on the export of cryptography which had been imposed by the United States. The server, Sioux, was a fork of the Apache HTTP server; it was later integrated with the Stronghold web server as Thawte began to concentrate more on their certification activities. In 1999, Verisign acquired Thawte in a stock purchase from Shuttleworth for US $575 million. Both Verisign and Thawte had certificates in the first Netscape browsers, and were thus "grandfathered" into all other web browsers. Before Verisign's ...

Finance
Finance is the study and discipline of money, currency and capital assets. It is related to, but not synonymous with economics, the study of production, distribution, and consumption of money, assets, goods and services (the discipline of financial economics bridges the two). Finance activities take place in financial systems at various scopes, thus the field can be roughly divided into personal, corporate, and public finance. In a financial system, assets are bought, sold, or traded as financial instruments, such as currencies, loans, bonds, shares, stocks, options, futures, etc. Assets can also be banked, invested, and insured to maximize value and minimize loss. In practice, risks are always present in any financial action and entities. A broad range of subfields within finance exist due to its wide scope. Asset, money, risk and investment management aim to maximize value and minimize volatility. Financial analysis is viability, stability, and profitability asse ...
