Who is the book for?
This book has been written for people whose first language is not English, and who use or
are going to use computers and other information technology in an English-speaking
environment. It covers the language needed to use information technology equipment,
work with computer programs, discuss problems and plan projects. It does not cover
advanced technical vocabulary for computer programmers or electronic engineers. All the
language in the book is intended to be accessible to intermediate level students and above....
In 1952, a major computing company took a decision to get out of the business of making mainframe computers. They
5 believed that there was only a market for four mainframes in the whole world. That company was IBM. The following year they reversed their decision.
Trong những năm vừa qua, nhiều tổ chức, tập đoàn công nghệ thông tin lớn đã chọn công nghệ Grid Computing làm chiến lược phát triển của mình, đã đầu tư nghiên cứu nhằm sớm đưa công nghệ Grid Computing vào thực tế. Công nghệ này đang ngày càng thu hút được sự quan tâm chú ý từ khắp nơi trên thế giới.
information technology industry is the application of technology management and information processing
IT industry to use computers and computer software to convert, store, protect, process, transmit, and gather information. This book is for those materials and specialized information technology and computers, including the words, English grammar information technology industry.
Tính toán và lưu trữ dạng “đám mây” chuyển các tài nguyên vật lý (như bộ vi xử lý và thiết bị lưu trữ) thành các tài nguyên mở rộng được và chia sẻ được trên Internet (tính toán và lưu trữ dưới dạng các “dịch vụ”). Mặc dù không phải là một khái niệm mới nhưng ảo hóa (virtualization) khiến cloud computing trở nên dễ mở rộng và hiệu quả hơn nhiều thông qua việc chia sẻ các hệ vật lý với sự ảo hóa server.
A course for people studying computer science or working with computers. It covers a wide range of computing areas, giving practice in all four language skills. Particular emphasis is placed on the vocabulary and grammar of the English used in computer science.
Java(TM) Network Programming and Distributed Computing is an accessible
introduction to the changing face of networking theory, Java(TM) technology, and the
fundamental elements of the Java networking API. With the explosive growth of the
Internet, Web applications, and Web services, the majority of today's programs and
applications require some form of networking. Because it was created with extensive
networking features, the Java programming language is uniquely suited for network
programming and distributed computing....
Welcome to our online textbook, Computer Networking: A Top-Down Approach. We ( Jim Kurose,
Keith Ross, and Addison-Wesley-Longman) think you will find this textbook to be very different than
the other computer networking books that are currently available. Perhaps the most unique and
innovative feature of this textbook is that it is online and accessible through a Web browser. We
believe that our online format has several things going for it.
The concept of IT is understood and defined in the Government Resolution 49/CP dated 04/08/1993 signed: Information Technology is a collection of scientific methods, the means of existing techniques and tools university - mainly computer technology and telecommunications - to organize the exploitation and efficient use of resources and information rich potential in all areas of human activity and society.
This book is an introduction to computer science. Computer science is the study of
computer hardware, algorithms, and data structures and how they fit together to provide
information systems. Each of these topics can be studied at various levels. For example,
physicists study the properties of matter that allow hardware components to be designed,
electrical engineers study how the components can be combined to produce circuits, and
computer engineers study how circuits can be combined to produce computers.
Computer technology has made incredible progress in the past half century. In
1945, there were no stored-program computers. Today, a few thousand dollars
will purchase a personal computer that has more performance, more main memory,
and more disk storage than a computer bought in 1965 for $1 million. This
rapid rate of improvement has come both from advances in the technology used
to build computers and from innovation in computer design. While technological
improvements have been fairly steady, progress arising from better computer
architectures has been much less consistent.
Information communications technology (ICT) has been found to be one of the most potent tools for promot-
ing equity and access to education, and a great resource in bridging the gap of the digital divide. ICT affects
almost all of our everyday activities, be it business, defense, or space exploration. Being informed of the latest
information has become essential for survival. Educational enterprises also beneft from the advantages and
technological learning tools offered by ICT. ICT is indispensable for creating effective distance education learn-
Eric H. Glendinning is Director of the Institute of Applied Linguistics at the University of Edinburgh in the UK. He has worked in teaching English in Tanzania, Norway, Nepal, and the United Kingdom and former Research Director of the Edinburgh Language Organization. John McEwan is the computer staff at the Institute of Applied Linguistics, University of Edinburgh. He is an experienced mathematics and physics teacher and teaching study skills, computers, and learning computer languages supported in the EFL language schools.
This is the first in a series of three books about computer
viruses. In these volumes I want to challenge you to think in new
ways about viruses, and break down false concepts and wrong ways
of thinking, and go on from there to discuss the relevance of
computer viruses in today’s world. These books are not a call to a
witch hunt, or manuals for protecting yourself from viruses. On the
contrary, they will teach you how to design viruses, deploy them,
and make them better. All three volumes are full of source code for
viruses, including both new and well known varieties....
Cloud Computing: Implementation, Management, and Security provides an understanding of what cloud computing really means, explores how disruptive it may become in the future, and examines its advantages and disadvantages. It gives business executives the knowledge necessary to make informed, educated decisions regarding cloud initiatives.
The authors first discuss the evolution of computing from a historical perspective, focusing primarily on advances that led to the development of cloud computing.
Computing for Numerical Methods Using Visual C++ has been written to promote
the use of Visual C++ in scientiﬁc computing. C++ is a beautiful language that
has contributed to shaping the modern world today. The language has contributed
to many device drivers in electronic equipment, as a tool in the development of
many computer software programs, and as a tool for both research and teaching.
Therefore, its involvement in providing the solution for numerical methods is very
Single processor supercomputers have achieved great speeds and have been pushing
hardware technology to the physical limit of chip manufacturing. But soon this trend
will come to an end, because there are physical and architectural bounds, which limit
the computational power that can be achieved with a single processor system. In this
book, we study advanced computer architectures that utilize parallelism via multiple
This handbook provides assistance in securing computer-based resources (including hardware,
software, and information) by explaining important concepts, cost considerations, and
interrelationships of security controls. It illustrates the benefits of security controls, the major
techniques or approaches for each control, and important related considerations.
