The computers have gained a lot of importance in the past five decades. Most of our day-to-day jobs are being influenced by the use of computers. Now a day, computers are used for performing almost every function, which were performed by humans in the past. In some areas such as science and technology, targets can’t be achieved without the use of computers. The characteristics the make the computer so important includes its extra ordinary speed, large storage capacity, accuracy and consistency.

Today computers play a great role in various industries and a large numbers of industries are using computer for various applications such as maintaining cashbook, sales book, purchase book, and other books of accounts. Computer can also be used for the designing of the various products. Computers provide many options for the designing of products.

In this project report, steps have been taken for computerizing Telephone Management System. The analysis of the project has been

undertaken with utmost sincerity and honesty and we will be extremely satisfied if the effort is appreciated.
