Q1)
a) Intelligent terminal vs Dumb terminal
A terminal is a computer term for a UI used to display the output and also the input of data into the system. A dumb terminal is a terminal which is simply a screen which does no processing or storage of data. An intelligent terminal on the other hand is a smarter terminal which can do processing of data and also the storage of the data such as a PC which can store the information and also process the information.
b) ROM chips vs RAM chips
ROM is Read Only Memory and is a non-volatile storage medium which does not lose the data stored in it when there is lack of power to the system. ROM is mean for the permanent storage of the data in the computer system, primarily used in the startup process of a computer. Whereas a RAM is Random Access Memory, it is a volatile storage medium and requires constant power to retain the information in it. A RAM is used in normal operations of a computer in the OS and computer such as executing the applications by the processor. ROM is slower than RAM. Size of RAM is much higher than the ROM.
c) Machine Language vs Fourth Generation Languages
A machine language is a programming language which consists of binary or hexadecimal instructions which is the language which the computer can directly understand and respond in the language only. The Fourth Generation Languages or the procedural languages are the high level languages which aim to provide higher level of abstraction of the internal computer hardware details and makes the programming very programmer friendly. Generally, all the languages such as Fourth Generation Languages convert the code to machine language code so that the computer can understand.
d) System Software vs Application Software
Application software is the type of software which helps the user in executing or controlling specific tasks and jobs for example Microsoft Office for editing and forming documents or presentations. System Software is the type of software which helps the computer to manage the system resources and also the Application software runs on top of the System software. System software example is computer Operating system such as Windows. An application software will be unable to run without a system software.
