Stanford University's Computer Science

Stanford University's Computer Science Department is part of the School of Engineering. The department offers the degrees Bachelor of Science, Master of Science, and Doctor of Philosophy. It also participates in the following undergraduate inter-disciplinary programs: Computer Systems Engineering, Symbolic Systems, and Mathematical and Computational Sciences.

Founded in 1965, the Department of Computer Science is a center for research and education at the undergraduate and graduate levels. Strong research groups exist in areas of artificial intelligence, robotics, foundations of computer science, scientific computing, and systems. Basic work in computer science is the main research goal of these groups, but there is also a strong emphasis on interdisciplinary research and on applications that stimulate basic research.

Fields in which interdisciplinary work has been undertaken include chemistry, genetics, linguistics, physics, medicine and various areas of engineering, construction, and manufacturing. Close ties are maintained with researchers with computational interests in other university departments. In addition, both faculty and students commonly work with investigators at nearby research or industrial institutions. The main educational goal is to prepare students for research and teaching careers either in universities or in industry.

Founded in Melbourne, Australia in 1978, Computershare (ASX: CPU) has grown (largely through overseas acquisitions) to become the world's largest share registry business.In brief, Computershare is a leading financial market services and technology provider managing over 14,000 corporate accounts totalling over 100 million shareholder accounts. Basically, Computershare specializes in the corporate trust, stock transfer and employee share plan services for thousands of issuers and millions of securityholder accounts.

Some twenty years after its founding, in 1997, the Australian-based company Computershare began to expand its evergrowing registry business to include financial markets in New Zealand and the United Kingdom.

In subsequent years, Computershare expanded its business into Ireland, South Africa, and Hong Kong. Since the year 2000, Computershare had extended its global position by acquiring an important role in the American and Canadian markets. In particular, through the acquisition of the stock transfer sectors of Harris Bank in the US and Montreal Trust in Canada. Moreover, since 2004, Computershare has made itself present in emerging markets such as Russia and India by amassing considerable stock in respective registry market's. Also in 2004, by purchasing Pepper Global, formerly Pepper Technologies AG, Computershare expanded into the German market. For the most part, the entry into these new markets were accomplished through financial acquisitions of existing registrar corporations.

computer technology

A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format.

Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers. Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.^[2] Simple computers are small enough to fit into small pocket devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.

The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a netbook to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity

An operating system

An operating system, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer would be useless.
As computers have progressed and developed so have the types of operating systems. Below is a basic list of the different types of operating systems and a few examples of operating systems that fall into each of the categories. Many computer operating systems will fall into more than one of the below categories.
GUI - Short for Graphical User Interface, a GUI Operating System contains graphics and icons and is commonly navigated by using a computer mouse. See our GUI dictionary definition for a complete definition.

A multi-user operating system allows for multiple users to use the same computer at the same time and/or different times. See our multi-user dictionary definition for a complete definition for a complete definition.An operating system that is capable of allowing multiple software processes to run at the same time

Computer Engineering

Assuming you haven't been living in a cave or under a rock for the last few decades, you are probably aware that an amazing computer revolution has rapidly changed the way much of the world works. Developments in radio, television, radar, transistors, computers, and robotics have fundamentally altered human life. The field of Computer Engineering is at the epicenter of this development. It encompasses a wide range of topics including operating systems, computer architecture, computer networks, robotics, artificial intelligence, and computer-aided design. If you major in Computer Engineering, you'll learn all about the hardware and software aspects of computer science. You'll gain a solid understanding of circuit theory and electronic circuits, too. Also, because Computer Engineering is closely linked with Electrical Engineering, the fields are found in the same department at many universities. Consequently, many undergraduate programs incorporate most of the core curricula in both electrical engineering and computer science so graduates will be prepared to work in either field. Computer Engineering is a difficult major but it's a major that's in demand. Software engineering companies, telecommunications firms, designers of digital hardware, and many other business enterprises hire Computer Engineering majors right out of college and pay them well. Computer Engineering also makes great preparation for medical school, business school, and law school

Networking and the Internet

Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems like Sabre.[32]
In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology. This effort was funded by ARPA (now DARPA), and the computer network that it produced was called the ARPANET.[33] The technologies that made the Arpanet possible spread and evolved.
In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer. Initially these facilities were available primarily to people working in high-tech environments, but in the 1990s the spread of applications like e-mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.

Computer science

Computer science or computing science is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems. It is frequently described as the systematic study of algorithmic processes that create, describe, and transform information. According to Peter J. Denning, the fundamental question underlying computer science is, "What can be efficiently automated?" Computer science has many sub-fields; some, such as computer graphics, emphasize the computation of specific results, while others, such as computational complexity theory, study the properties of computational problems. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describe computations, while computer programming applies specific programming languages to solve specific computational problems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to people.
The general public sometimes confuses computer science with careers that deal with computers. computer is such as the noun Information Technology, or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones.
