Meaning and Elements of Computer System
These days bookkeeping and accounting is rarely done manually. Like all things in life, we rely on technology to help us with accounting as well. Computers have become almost a necessity for us, and it is no different in accountancy as well. So it is important to learn about computer systems and the elements of a computer system.
Computer Systems
We are all aware of what computers are and their immense importance in our daily lives. It is an electronic device that not only stores data but also processes and manipulates data to carry out functions. Upon receiving valid instructions, a computer can perform a variety of operations.
What allows us to perform such tasks on the computer is a computer system. A computer system is the sum total of all the components (hardware and software) that make up a fully functional computer.
Elements of a Computer System
There are six main elements that make up a computer system. They all interact with each other and perform the task at hand. Let us take a look at all of them.
1. Hardware
These are all the physical aspects of a computer system. They are tangible, i.e. you can see and touch them. Hardware components are electronic or mechanical instruments, like a keyboard, monitor, printer etc. They help the users interface with the software, and also display the result of the tasks being performed.
Hardware can actually be of four types, depending on which function they perform. The four types of hardware are,
- Input Hardware: For users to input data into the computer system. Examples: Keyboard, mouse, Scanner
- Output Hardware: To translate and display the result of the data processing =. Example: Monitor Screen, Printer, etc
- Processing and Memory Hardware: Where data and information are processed and manipulated to perform the task at hand. It is also the workspace of the computer, where it temporarily stores data. Examples: Central Processing Unit (CPU), Read-Only Memory (RAM)
- Secondary Storage Hardware: Where the computer system stores data permanently. Example: Harddisk, Pendrive, etc
2. Software
Software is nothing but a set of programmes (computer instructions), which help the user to do a set of specific tasks. It helps the user interact with the computer system with the help of hardware. Software, as you can imagine, is the intangible aspect of the computer system.
Basically, there are six main types of software, which are as follows:
Operating System: These specialized programmes allow communication between software and hardware. The operating systems run all the other computer programmes, and even regulate the startup process of the computer. Examples: Windows XP, Macintosh, etc
Application Software: These are designed to perform a specific task or a bunch of tasks. They can be user-designed (specific to the user’s needs) or readymade application software. Example: PowerPoint, Tally, etc.
Utility Software: Like operating systems, it is system software. It helps maintain and protect the computer system. For example, Anti-virus software is utility software.
Language Processors: Software that interprets computer language and translates it into machine language. It also checks for errors in language syntax and fixes the problems.
System Software: This types of software control the hardware, the reading of the data and other such internal functions.
Connectivity Software: The special software that facilitates the connection between the computer system and the server. This allows the computer to share information and communicate with each other.
3. People
The people interacting with the computer system are also an element of it. We call this element the Liveware. They are the ultimate “users” of computer systems. There are three types of people that interact with the system, namely
Programmers: Professionals who write computer programs that allow users to interact with the computer. They must have technical knowledge of computers and computer languages.
System Analyst: They mainly design data processing systems, and solve problems that arise in the data processing.
End-Users: Also known as operators, they are the people who interact with the computer system.
4. Procedures
These are a set of instructions, written in code, to instruct a computer on how to perform a task, run software, do calculations, etc. There are three types of procedures in a computer They are,
- Hardware-Oriented Procedure: Instructs the hardware components of the system, ensures they work smoothly.
- Software Oriented Procedure: Provides instructions to launch and run software programs.
- Internal Procedures: Directs the flow of information and sequences the data.
5. Data
Data is essentially the raw facts and figures that we input into the computer. The data gets processed via the computer system and becomes information, which is processed and organized data. Information can then be used for decision-making purposes.
The measurement of data is done in terms of “bytes”. One kilobyte (KB) is approximately 1000 bytes, 1 megabyte (MB) is 1 million bytes and finally, 1 gigabyte (GB) is approximately 1 billion bytes.
6. Connectivity
This is when the computers are linked to a network. It facilitates sharing of information, files, and other facilities. Computers can connect to a network via LAN cables, Bluetooth, Wi-Fi, satellites, etc. The internet is the most obvious example of connectivity in a computer system.
Example:
Question:
A famous computerized accounting software, Tally, is which of the following?
a. Operating System
b. Application Software
c. Utility Software
d. None of the above
Answer:
The correct answer is “b”.
It handles accounting, inventory management, tax calculations, and other such important functions.
