Meaning of Computers: A computer is an electronic device, which is capable of performing a variety of operations as directed by a set of instructions. This set of instructions is called a computer programme.

Elements of a Computer System:
A computer system is a combination of six elements:

1. Hardware: Hardware of computers consists of physical components such as keyboard, mouse, monitor, processor etc. These are electronic and electronic mechanical components.

2. Software: In order to solve a particular problem with the help of computers, a sequence of instructions written in proper language will have to be feed into the computers. A set of such instructions is called a ‘Program’ and the set of programs is called ‘Software’. For example, a computer by feeding a particular software can be used to prepare payroll, whereas by feeding a second software it can be used to prepare accounts, by feeding a third software it can be used for inventory control and so on.

3. People: People are basically those individuals who use hardware and software to develop, maintain and use the information system residing in the computer memory. They constitute the most important part of the computer System. The main categories of people involved with the computer system are:
a. System Analysis
b. Operators
c. Programmers

4. Procedures: The Procedure means a series of operations in a certain order or manner to achieve desired results. These are of three types:
a. Software-Oriented: Provides a set of instructions required for using the software of a computer system.
b. Hardware-Oriented: Provides details about the components and their methods of operations.
c. Internal Procedure: Helps to ensure smooth flow of data to computers sequencing the operations of each sub-system of overall computer system.

5. Data: These are facts (may consist of numbers, text etc.) gathered and entered into a computer system. The computer system in turn stores, retrieves, classifies, organises and synthesis the data to produce information when desired.
Examples:
1. Bio-data of various applicants when the computer is used for recruitment of staff.
2. Marks obtained by various students in various subjects when the computer is used to prepare results.

6. Connectivity: the manner in which a particular computer system is connected to others (say through telephone lines, microwave transmission satellite link etc.) is called element of connectivity.

Capabilities or Advantage of Computer System
A Computer system posses the following advantages in comparison of human beings:

1. High Speed: Computers are known for their lightening speed of operations and requires less time in comparison to human beings in performing a task. Most of modern computers perform millions of operations in one second.
2. Accuracy: Computers are extremely accurate. Their operations are error free and as such the information obtained from it is highly reliable. But sometimes errors occur due to bad programming or in accurate data feeding. In computer terminology, it refers is called Garbage in, garbage out (GIGO).
3. Reliability: Its reliability refers to the ability with which computer remains functional to serve the user. Unlike human beings these are immune to tiredness, boredom or fatigue, and can perform jobs of repetitive nature any number of times.
4. Versatility: It refers to the ability of computers to perform a variety of tasks. It can switch over from one programme to another. The same computer can be used for accounting work, stock control, sales analysis and even for playing games by the use of different softwares.
5. Storage: Memory or Storage capacity of a computer is so large that it can store any volume of information or data. Such data can be stored in it on magnetic discs, floppy discs, punched cards or microfilms etc. The information stored can be recalled at any time and also correction can be done within no time.

Limitations: Inspite of so many qualities, computers suffer from the following limitations.

1. Lack of Common sense: Since computer works according to the stored programms, it is simply lack of common sense.
2. Zero I.Q.: Computers are dumb devices with zero Intelligence Quotient (IQ). They can’t visualize and think what exactly to do under a particular situation unless they are programmed to tackle that situation.
3. Lack of Feeling: Computers lack feelings like human beings because they are machines. No computer passes the equivalent of a human heart and soul.
4. Lack of Decision-making: Decision making is a complex process involving information, knowledge, intelligence, wisdom & ability to judge, Computers cannot make decisions of their own.

Some more limitations related to computerised System in Accounting

1. High Cost of Training: Besides the high cost of computer system, huge money is required to get the trained specialised staff to ensure efficient and effective use of computerised systems.
2. Danger of System Failure: The danger of system crashing due to hardware failure and the subsequent loss of word is a serious limitation of this system.
3. Staff Opposition: Whenever the Accounting System is computerised, there is a significant degree of resistance from the existing staff because of the fear that they shall be less important to the organisation.
4. Disruption: The accounting process suffer a significant loss of work and time when an organisation switches over to this system. This is due to the changes in the working environment that requires accounting staff to adapt to new system and procedures.

Components of Computers
The functional components consist of Input Unit, Central Processing Unit (CPU) and the output Unit explained as follows:

1. Input Unit: This unit is for entering the data into the computer system. Keyboard and Mouse are the most commonly used input devices. Other such devices are magnetic tapes, disc, light pen, optical scanner, smart card reader etc. Besides there are some devices which respond to voice and physical touch.
2. Central Processing Unit (CPU): It is the main part of computer hardware that actually processes the data according to the instructions it receives. It has three units:
Monitor Printer

a. Arithmetic and Logic Unit (ALU): Responsible for performing all the arithmetic calculations such as addition, subtraction etc. and logical operations involving comparison among variables.
b. Memory Unit: For storing the data.
c. Control Unit: Responsible for controlling and coordinating the activities of all other units of the computer system.
3. Output Unit: After processing the data, the information produced is required in human readable and understandable form. Output devices perform this function. The commonly used devices are monitor, printer, graphic plotter (external) and magnetic stage devices (internal). A new device which is capable of producing verbal output that is sound in human speech is also developed.

Operating Software
Operating Software is a set of programmes that is used by computers for various purposes. Operating Software is essential part of computer system in absence of operating software computer cannot operate. There are many operating soft- wares like Windows, Excel etc.

Utility Software
Utility Software is a set of computer programmes used to perform supporting operations in a
computer. Utility Software are highly specialised and designed to perform only a single task
or a small range of tasks.

Application Software
Application Software is the set of programmes which is designed and developed for performing certain task like accounting, word processing etc. for example Tally is the application software.

Comparison of Manual and Compute red Accounting System

Sourcing of Accounting Software
India is one of software making country. So, accounting softwares are easily available in Indian Market. But it is more important to know what is your need of accounting software. Generally, Tally accounting software is used in India which is easily available in market.

Accounting Softwares
1. Readymade Software: Readymade Softwares are the softwares that are developed not for any specific user but for the users in general. Some of the ready-made softwares available are Tally, Ex, Busy. Such softwares are economical and ready to use. Such softwares do not fulfill the requirement of very user.
2. Customised Software: Customised software means modifying the ready-made softwares to suit the specific requirements of the user Readymade softwares are modified according to the need of the business Cost of installation, maintenance and training is relatively higher than that of ready-made user. There packages are used by those medium or large business enterprises in which financial transactions are some what peculiar in nature.
3. Tailor-made Software: The softwares that are developed to meet the requirement of the user on the basis of discussion between the user and developers. Such softwares help in maintaining effective management information system. The cost of these softwares in very high and specific training for using these packages is also required.

Generic Considerations Before Sourcing Accounting Software
i. Flexibility: a computer software system must be flexible in respect of data handling and report preparing.
ii. Maintenance Cost: The accounting software must be such which has less maintenance cost.
iii. Size of organisation: The accounting software must be according to need and size of organisation.
iv. Easy to adaptation: The accounting software must be such which is easy to apply in organisation.
v. Secrecy of data: The accounting software provide the secrecy of business data.

Preparation of Accounts Groups
Groups of accounts means classifying the accounting transactions into different heads like Assets Group, Liabilities Group, Income Group and Expenses Group. By these grouping of accounts the final Accounts are meaningful for its users.

Generation of Accounting Reports
After collecting business data, it is converted into meaningful informations. Such summarised and converted information is known as a report.
The report is more effective if it is based on accurate and timely data.
A report must be relevant to users and contain all relevant information like Debtor’s Report, Creditor’s Report, Trial Balance and Financial Statement Report and others.
