1. Answer the questions:

  1. How is computer programming language called?

  2. May source code be converted into an executable image by a compiler or executed immediately with the aid of an interpreter?

  3. What is the main disadvantage of interpreters?

  4. Object code needs further processing to become machine code, doesn’t it?

  5. Can compiled or interpreted programs be executed in a batch process without human interaction?

2. True or false:

  1. A computer program in the form of a human readable, computer programming language is called driver.

  2. Compilers aren’t used to translate source code from a programming language into either object code or machine code

  3. The main disadvantage of interpreters is that computer programs run slower than when compiled.

  4. Software development may be slower using an interpreter.

  5. Byte-code is then executed on request by an interpreter called a virtual machine.

3. Choose the right preposition:

  1. A computer program in the form … a human-readable.

1. off 2. of 3. for

  1. Interpreted programs allow a user to type commands … an interactive session.

1. from 2. in 3. at

3) ...contrast, compiled computer programs need no compiler present during execution.

1. on 2. at 3. by

4) The categorization usually reflects the most popular method … language execution.

1. in 2. of 3. for

5) Byte-code is then executed on request ... an interpreter called a virtual

machine.

1. by 2. in 3. at

4. Choose the following words:

  1. A computer … in the form of a human readable, computer programming language is called source code.

1) code 2) program 3) driver

  1. Either compiled or interpreted programs might be … in a batch process without human interaction, but interpreted programs allow a user to type commands in an interactive session.

1) used 2) performed 3) executed

  1. Byte-code is then executed on request by an interpreter called a … machine.

1) virtual 2) real 3) virtualization

  1. Another ... of interpreters is that at least one must be present on the computer during computer program execution.

1) lack 2) disadvantage 3) advantage

  1. Some systems use just in time compilation (JIT) whereby sections of the source are compiled 'on the fly' and ... for subsequent executions.

1) stored 2) save 3) keep

Text 10 Term information technology

In the 1960s and 1970s, the term information technology (IT) was a little known phrase that was used by those who like banks and hospitals to describe the processes they used to store information. With the paradigm shift to computing technology and "paperless" workplaces, information technology has come to be a household phrase. It defines an industry that uses computers, networking, software programming, and other equipment and processes to store, process, transmit, and protect information.

In the early days of computer development, there was no such thing as a college degree in IT. Software development and computer programming were best left to the computer scientists and mathematical engineers, due to their complicated nature. As time passed and technology advanced, such as with the advent of the personal computer in the 1980s and its everyday use in the home and the workplace, the world moved into the information age.

By the early 21st century, nearly every child in the Western world, and many in other parts of the world, knew how to use a personal computer. Businesses' information technology departments have gone from using storage tapes created by a single computer operator to interconnected networks of employee workstations that store information in a server farm, often somewhere away from the main business site. Communication has advanced, from physical postal mail, to telephone fax transmissions, to nearly digital communication through electronic mail (email). Great technological advances have been made since the days when computers were huge pieces of equipment that were stored in big, air conditioned rooms, getting their information from punch cards. The information technology industry has turned out to be a huge employer of people worldwide, as the focus shifts in some nations from manufacturing to service industries. It is a field where the barrier to entry is generally much lower than that of manufacturing, for example. In the current business environment, being proficient in computers is often a necessity for those who want to compete in the workplace.

Jobs in information technology are widely varied, although many do require some level of higher education. Positions as diverse as software designer, network engineer, and database administrator are all usually considered IT jobs. Nearly any position that involves the intersection of computers and information may be considered part of this field.
