Tech Differences

We all are aware of ROM i.e. Read-Only Memory which contains the data required to boot up the computer system. It is a non-volatile memory, and it can not be modified easily or even sometimes not at all. But the modern ROM can be erased and reprogrammed in some way. Today we have modified version of ROM that are EPROM (Erasable Read-Only Memory) and EEPROM (Electrically Erasable Read-Only Memory). EPROM and EEPROM can be erased and reprogrammed again but at a very slow speed. Erasing requires … [Read more...]

Register and memory, hold the data that can be directly accessed by the processor which also increases the processing speed of CPU. The processing speed of CPU can also be increased by increasing the number of bits of the register or increasing the number of the physical register in the CPU. Same is the case with memory, more the amount of memory faster is the CPU. Memory is genereally referred to the primary memory of the computer. Despite these similarities, the register and memory share … [Read more...]

Compiler and Assembler plays an important role in the execution of a program. Some compilers directly generate the executable code instead of assembly code. The compiler takes the preprocessed source code and translates it into the assembly code. The assembler takes the assembly code from the compiler and translates it to the relocatable machine code. In this article, I have discussed the differences between compiler and assembler with the help of comparison chart shown below, just have a … [Read more...]

Linker and Loader are the utility programs that plays a major role in the execution of a program. The Source code of a program passes through compiler, assembler, linker, loader in the respective order, before execution. On the one hand, where the linker intakes the object codes generated by the assembler and combine them to generate the executable module. On the other hands, the loader loads this executable module to the main memory for execution. Let us discuss the difference between Linker … [Read more...]

RAM and ROM both are the internal memories of the computer. Where RAM is a temporary memory, ROM is a permanent memory of the computer. There are many differences between RAM and ROM, but the basic difference is that RAM is a read-write memory and the ROM is a read only memory. I have discussed some differences between RAM and ROM with the help of comparison chart shown below. Content: RAM Vs ROM Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

Supercomputer and mainframe computers are the most powerful computers. But they can be distinguished by the tasks they perform. On the one hand where supercomputer focuses on a fast computation of complex mathematical operations. On the other hands, the mainframe computer acts as a server and support large database, vast I/O devices, and multiprogramming. Let us discuss some more differences between supercomputer and mainframe computer with the help of comparison chart shown below. Content: … [Read more...]

The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept. The basic difference between primary and secondary memory is that the primary memory is directly accessible by CPU whereas, the secondary memory is not directly accessible to … [Read more...]
