DK Goel Solutions Class 11 Chapter 24 Introduction to Computers DK Goel Accountancy Class 11 Solutions Chapter 24 Introduction to Computers, which is laid out by master Accountancy instructors from the most recent form of DK Goel Class 11 Accountancy books. We, at Dk Goel Solutions help students to fathom every one of the hypotheses, specifically. There are various ideas in Accountancy, however the ideas of Trial Balance, Depreciation and Bank Reconciliation Statement (BRS) are required. DK Goel Solutions Class 11 – Chapter 24 Short Answer Questions Question 1: What is a computer? What are its important features? Solution 1: For doing calculations, a computer is an automated electronic system. But a mere computing machine should not be described because it is capable of answering questions on the basis of the data stored within it.

2. Some essential device features are described below:— 1. A computer is an electronic machine:- Once the data and commands are fed into a computer, without human interference, it executes them one by one. 2. Memory or Storage:- A computer’s memory is so huge that every amount of information or data for retrieval can be stored. 3. Fast Speed:- Computers are renowned for their computational lightning speed. The velocity is so large that in microseconds it is usually expressed. Question 2: Give three features of a computer. Solution 2: The features of a machine are below:— 1. Diligence:- After long working hours, a man can experience mental and physical failure, but like a human being, a machine never gets exhausted. For several days at a time, it will run constantly and never say, “I am too tired to do any more work.” In comparison, it does not suffer from a loss of focus and can do the job repetitively any amount of times, just the same way. 2. Scientific approach:- When solving the dilemma, a machine works logically and never gets emotional. 3. Versatile machine:- A computer can handle a large spectrum of jobs. According to the instructions fed in, it will switch from one program to another. Question 3: What is the difference between a computer and a calculator? Solution 3: There is much more to a computer than a calculator. A calculator can deal only for numbers, while both numbers and words can be controlled by a computer. Another distinction is that the data cannot be stored by a calculator, while a computer can store vast quantities of data in its memory and replicate some portion of it as and when necessary. Question 4: Explain the main parts of computer system with the help of a diagram. Solution 4: Below are the main parts of a computer:- 1. Keyboard:- ‘Input Devices’ are the devices or items that are used to feed data and programs into a computer. One such unit is a keyboard.

3. 2. Monitor:- On a panel known as a monitor or ‘output unit’, a computer shows the data, notifications or responses. On the computer, results are shown in a language that can be interpreted and understood quickly by the users. 3. Control Processing Unit or CPU:- This unit is a computer that consists of a set of complex electronic circuits and is the primary and most important component of a computer. The Processor is the machine’s brain or decision-making component that executes all the operations in conjunction with the software fed into the computer. Question 5: Give any three limitations of computer system. Solution 5: The computer device limitations are described below:— 1.) Absence of decision-making:- Computers are only good for decision-making, but they are unable to make choices on their own. Decision-making is a dynamic process that involves a great deal of expertise, facts, intellect and decision-making capacity. 2.) Lack of Intelligence Quotient:- Computers with Zero IQ are simple robots. In order to be able to manage the scenario, computers must be programmed beforehand. 3.) Lack of common-sense:- A common-sense programming interface is absent. A system may continue to run as per its programming and does not evaluate the logical or illogical nature of it. Question 6: What is keyboard? Solution 6: ‘Input Devices’ are the devices or modules which are used to feed data and programs into a computer. One such unit is a keyboard. In binary language, the data that we want to feed into a machine can be typed on the keyboard. Punched cards, paper tapes, cassette tapes, magnetic discs, floppy discs etc. are the other input instruments. Question 7: Explain the magnetic recorder. Solution 7: This machine permanently retains information and data fed into a computer and is often referred to as a memory unit. There may be two forms of memory on a computer:—

4. (i) Volatile Memory:- It is only capable of briefly storing data. As soon as the power source is turned off or dies, the data contained in it is immediately erased. (ii) Non-Volatile Memory:- It is capable of indefinitely storing data. And if the power supply dies, the data stored within it is not erased. But the biggest downside of non-volatile memory is that it is only possible to read and not modify the data contained in it. Question 8: What are the advantages of word processor? Solution 8: The benefits of word processors are below:— 1.) Any word, line or paragraph previously typed may be changed, omitted or transferred to a different position instead of typing the same subject again. 2.) In a word processor, printing facilities are also available. We can get printed copies of the matter free of error and even without any indication of rectification of an error. 3.) When typed, the matter may be arranged in multiple formats, types, and also at the appropriate page width. 4.) The word processor also helps to verify words’ pronunciation. It requires a vocabulary and detects the words not contained in the dictionary in the typed matter automatically. Question 9: What is the use of Data Base Management? Solution 9: It records in one single location all the valuable and important information pertaining to a company. Usually, these data’s are stored on floppy disks and the Data Base Manager transforms the information into usable data. Data which refer to the various operations of the company, such as the regular purchasing and selling of goods, the selection of debtors, the expense and revenue of separate heads, etc. Question 10: What type of software’s are available for accounting purpose? Solution 10: Below are the software’s are available for accounting purpose:-

5. 1.) Tally (ERP) 2.) SAP 3.) Quick Books 4.) Busy Very Short Answer Questions Question 1: Give one feature of a Computer. Solution 1: An automatic system is a computer. If the information and instructions are fed into a computer, without human interference, it executes them one by one. Question 2: What is Binary System? Solution 2: Computers do not use the decimal system, instead they use the Binary System, a two-way system. The details contained in the machine under this scheme is in two digits only. All of these digits are 0 and 1. Question 3: Give one difference between a computer and a calculator. Solution 3: There is much more to a computer than a calculator. A calculator can deal only for numbers, while both numbers and words can be controlled by a computer. Question 4: Give the names of two languages used by a computer. Solution 4: (i) BASIC

6. (ii) COBOL Question 5: Can a Computer take a decision? Solution 5: CPU is the brain or decision making portion of the computer that executes all of the operation in conjunction with the program fed into the computer. Indeed, compute will take a decision.
