Short Answer Questions for DK Goel Solutions Class 11 Chapter 24

Question 1:

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.
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:

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:

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:

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.
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:

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:

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:

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:—
(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:

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:

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:

Solution 10:
Below are the software’s are available for accounting purpose:-
1.) Tally (ERP)
2.) SAP
3.) Quick Books
4.) Busy

Question 11:

Solution 11:
Distinctions between Hardware and Software:-

Question 12:

Solution 12:
In several ways, algorithms have enhanced the productivity of the accounting department. The job that was previously done by hundreds of clerks is done very quickly and without a single error by the computer.

The use of computers in accounting work is also growing day-by-day, and very quickly it will be impossible to find an accounting department in a medium-sized organization that does not use a computer.

Question 13:

Solution 13:
(i) Hardware:- All of the previously discussed digital machines are known as hardware. Keyboard, display, C.P.U., magnetic recorder, etc.

(ii) Software:- A sequence of instructions written in the correct language will have to be fed to the computer in order to solve a problem with the help of the computer. A set of such instructions is referred to as a “program” and the program set is referred to as software. A computer machine can only be used for different purposes by changing the program. Six types of software exist:—
(1) Operating System
(2) Utility Software
(3) Application Software
(4) System Software
(5) Language Processors
(6) Connectivity Software

(iii) Computer applications in accounting:- Computers have, in many ways, increased the efficiency of the accounting department. The job that was traditionally performed by hundreds of clerks is accomplished very easily and without a single mistake by the machine. The use of computers in accounting work is also growing day-by-day, and very quickly it will be impossible to find an accounting department in a medium-sized organization that does not use a computer.

Question 14:

Solution 14:
The capabilities of the computer system are 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 high that it is usually expressed in microseconds (1 microsecond = 1/10,00,000 seconds).
4. Accuracy:- Computers are incredibly precise. Their activities are error-free and, as such, the data obtained from them is extremely reliable.

Question 15:
