A computer is a digital electrical machine that can be programmed to perform arithmetic or logical operations in a predetermined sequence. Programs are generic collections of operations that modern computers can do. These programs allow computers to carry out a variety of tasks. Computer TermsDescription ProcessorA processor is a type of integrated electrical circuit that performs the calculations that allow a computer to function. It is the part that runs executable programs. An operating system sends arithmetic, logical, input/output (I/O), and other basic instructions to a processor, which it executes (OS). The operations of a processor are required for the majority of other processes. RAMRAM stands for "random access memory," A computer's RAM is the super-fast and temporary data storage space that it requires. Random-access memory (RAM) is a sort of data storage that is commonly found on the motherboard of computers. Because it is much faster to read and write than other forms of storage€”between 20 and 100 times faster than hard disks. it is the primary memory utilized by a computer for quick access. Hard DiskThe hard disk is a secondary storage device, which is designed to store data permanently. The secondary storage devices include a large storage capacity as compared to the primary storage devices. The data stored in a hard disk is retained when our computer system shuts down. The data stored in the hard disk can be of many types such as the operating system, installed software, documents, and other files of a computer. CompilerA compiler is software that converts source code into object code. it translates high-level language to machine/binary language. It is the part that translates the source program to an executable program. The compilation is the process of translating source code into machine code. Therefore, the correct sequence is (A)-(I), (B)-(III), (C)-(II), (D)-(IV)
