Fundamentals of Computers

This is the input device in a computer that consists of a lever that moves in all directions and controls the movement of a pointer or some other display symbol.

This processor mode in a computer system is the one which provides running of DOS program in the windows operating system.

This component of motherboard is a type of memory chip to store the date, time and system setup parameters.

 In a distributed system, all machines are standalone. They do not share memory.

This device in a computer consists of a small rubber projection embedded between the keys of the keyboard.

This BUS in a computer system is also called as timing and control BUS which is used to control and coordinate the CPU operations.

This characteristic of computer states that a computer can continually work for hours without creating any error.

This feature of performance enhancement of a system implements a base for parallel computing and measures the number of operations executed in a computer simultaneously.

This is a method of running CPU at the speed more than the actual rated to increase the performance.

This type of RAM must be refreshed continually to store information or otherwise it will lose the data it is holding.

This type of ROM memory consists of cell that includes a field effect transistor having a selection gate, a floating gate, a source and a drain.

This component of computer is used to connect external devices like printers, keyboards or scanners to the computer.

This is a power supply component of a computer system that converts AC power from an electrical outlet to the DC power needed by system components.

This operating system is a computer or group of computers that provides services to other computers connected via network.

This potential pitfall of CPU overclocking is the one in which the CPU is not cooled properly due to which die time of the CPU maximizes its exceeded temperature limit and causes failure.
