Without any shadow of a doubt, it can be considered that the 21st century is technological century as the whole humankind have been using different types of electrical appliances or other techniques on their daily basis. One of the greatest and widespread technologies is computer and internet. Computer is used all spheres of life like housing, cooking, taking care of ill people, nursing and of course teaching. As teaching is essential part of the life as well as computers are also considered as the best friend of humankind, both objectives of life can be put together. There are two phrases to differentiate each other:

1) Computer language that is a formal language used in communication with a computer. Types of computer languages include: Construction language – all forms of communication by which a human can specify an executable problem solution to a computer.

2) Computer assisted language that is an approach to teaching and learning in which the computer and computer-based resources such as the Internet are used to present, reinforce and assess material to be learned. It usually includes a substantial interactive element.

The technologies used in CALL (Computer Assisted Language Learning) instruction generally fall into two categories, software and Internet-based activities.

Software - software used in a CALL environment can be designed specifically for foreign/second language learning or adapted for this purpose. Most language textbook publishers offer educational software of some sort, whether it is meant to support a paper textbook or to stand alone for self-study.

Most programs designed for language learning are tutorials. These generally are drill programs that consist of a brief introduction plus a series of questions to which the learner responds and then the computer gives some kind of feedback. With these kinds of programs, the material to be learned may already be programmed in by the publisher, which is more common, or may allow the instructor to program in the material to be learned.

Programs not designed specifically for language learning can be adapted for this purpose. Generally, these are task-based activities where the stated goal is something other than language learning; however, using the target language is essential for getting the task done. For example, with facemaker, students create different faces by using words in the language to command the computer. Role-playing games, where the user creates and controls a character in a fantasy realm, can be used in this manner as well.

Internet-based - The World Wide Web was launched in 1992 reaching the general public by 1993, opening up new possibilities in CALL. Internet activities vary considerably, from online versions of software (where the learner interacts with a networked computer), to computer-mediated communication (where the learner interacts with other people via the computer), to applications that combine these two elements.

Teaching or learning a foreign language is not an easy matter. Most of time it depends on both teacher and learner as well. In order to reach the success, educators can:

- Expose students to as much of the language as possible - While this may sound like an obvious thing to do, it is not always utilized in classrooms. Limit the native language and focus on the target one in your interactions with your students. Even if they don’t know any of the target language, they can still easily learn simple classroom commands.

- Get hands-on: Encourage participation with games - Learning a new language cannot be a passive experience; get your students involved utilizing games and role-playing. Grammar exercises can be turned into participatory games that encourage students to think on their feet. Role-playing is essential for recreating real-world scenarios in which students would use their language skills.

- Encourage activities outside the classroom. To effectively learn a new language, students need to be as engaged as possible even when outside of the classroom.

- Teach culture alongside the language. It’s not enough to simply teach speaking; students must understand the meaning behind the language. Unveiling the culture from which the target language originates is essential in helping the student appreciate the true depth of the words being taught.

- Use multimedia to enhance the learning experience. The problem most language students have after learning in the classroom is the inability to communicate effectively in the country of the language. We each know at least one person who studied many years of a language in high school, only to find him or herself incapable of ordering a coffee when it comes down to it.

As it can be seen, technology and teaching are connected with each other. Even teaching face to face needs technology but still a live lesson should be conducted.

CALL’s origins and development trace back to the 1960’s and since has consisted of a symbiotic relationship between the development of technology and pedagogy. Its development can be divided into three phases: behavioristic CALL, communicative CALL and integrative /explorative CALL. The current philosophy of CALL puts a strong emphasis on student-centred materials that allow learners to work on their own. Such materials may be structured or unstructured, but they normally embody two important features: interactive learning and individualized learning. CALL is essentially a tool that helps teachers to facilitate the language learning process. It can be used to reinforce what has already been learned in the classroom or as a remedial tool to help learners who require additional support.

To conclude, learning a foreign language with the help of computer can be really effective. However, a teacher or tutor’s lesson would be more live and helpful for a learner. There are several reasons for that, firstly, a student can feel natural lesson and give any question according to the theme, secondly, the learners are encouraged with the help of different methods by experienced teachers. At last, but not least, learners have a classroom environment to get the knowledge and the classroom environment is essential to cope with the intelligence. Although there are several ways to learn a language, I still believe that learning a foreign language should be done at classroom in any age. Then of course, practice can be done.
