There are several topics of difference between computer fundamentals are described below –
Difference Between Computer Hardware and Software
| Slno. | Hardware | Software |
| 1. | It is physical parts of the computer. | It is set of instructions given to the computer systematically. |
| 2. | We can touch, see and feel hardware of a computer/laptop. | We cannot touch and feel software present in a computer/laptop. |
| 3. | Hardware is made up of physical materials or components. | Software is developed by writing instructions/codes in English letters normally using certain programming language with proper rules and syntax by the programmer. |
| 4. | They are considered as the body of the human beings. | They are considered as soul of the human body. |
| 5. | It runs under the control of a suitable software. | It also runs under the control of a suitable higher software. |
| 6. | It is not affected by computer viruses. | It is affected by computer viruses/malware seriously. |
| 7. | Damaged hardware is being repaired/replaced by new or correct old one. | Damaged or corrupted software is recovered by its backup copy or by re-installing again. |
| 8. | It consists of input devices, output devices, storage/memory devices, and powerful processing elements mainly. | It consists of different types of specific software such as System software, Application software, Programming language software, Utility software, Device Driver software etc . |
| 9. | It can’t be transferred easily from one place to another. | It can be transferred easily from one place to another. |
| 10. | We cannot make new duplicate copy of it by copying. | We can make new duplicate copy easily by copying. |
| 11. | Hardware components wears out as time passes and finally destroyed. | Software components never wears out as time passes rather it remains as usual but becomes outdated only. |
| 12. | Hardware are comparatively slowly upgraded. | Software are fastly upgraded. |
| 13. | It is manufactured. | It is developed and engineered. |
| 14. | It is weighted/heavy. | It is weightless/light. |
| 15. | Examples are : Keyboard, Mouse, Monitor, Printer, CPU, Hard disk, RAM, ROM, Pen drive, Speakers, UPS etc. | Examples are : Ms Office, Photoshop, Tally, Antivirus, Operating Systems, Translators, Device Drivers, Games software etc. |
Difference Between Interpreter and Compiler
| Slno. | Interpreter | Compiler |
| 1. | Translates/scans code line by line i.e. one statement/line of code at a time. | Scans the entire program and translates it as a whole into machine code at a time. |
| 2. | It takes less amount of time to analyze the codes but the overall execution time is slower. | It takes a large amount of time to analyze the source code but the overall execution time is comparatively faster. |
| 3. |
Displays error of each line, one by one. |
Display all errors after compilation, all at the same time. |
| 4. | No intermediate object code is generated, hence are memory efficient. | Generates intermediate object code(.obj file) which further requires linking to create a .exe file to run the program, hence requiring more memory. |
| 5. |
Continues translating the program until the first error is met, and then pauses so debugging is easy. Here the interpreter reads a single statement and shows the error if any. Therefore, we must correct the error to interpret next line. |
It generates all the error messages only after scanning the whole program at a time and hence debugging is comparatively tough. Therefore, we can’t run the program without fixing all the errors. |
| 6. | It is best suited for the program and development environment. | It is best suited for the Production Environment. |
| 7. | Interpreters see code line by line, and thus optimizations are not as robust as compilers. | The compiler sees the entire code upfront. Hence, they perform lots of optimizations that make code run faster. |
| 8. | The interpreter exists in the memory during interpretation. | Target programs execute independently hence do not require to exists the compiler in the memory. |
| 9. | Interpreted code runs slower. | Compiled code run faster. |
| 10. | Not saving machine code at all. | Stores machine language as machine code on the disk of compiling code. |
| 11. | Interpreters are easier to use, especially for beginners. | Compilers are little difficult to use for beginners. |
| 12. | Interpretation (Compilation) and execution of the program takes place simultaneously. | The compilation is done before execution of the program. |
| 13. | Error detection is easier comparatively. | Error detection is difficult. |
| 14. | Examples are : Basic, Python, Ruby, Php, Perl etc. | Examples are : C, C++, C#, Java etc. |
