Drum is the name of a plotter as well as a printer. Drum printers have a predefined set of characters and print one line at a time. Drum plotters is an ideal device for architects and others who need to generate high-precision hard copy graphics output of widely varying sizes.

The Registers are the fast storage units. They are responsible for storing intermediate computational results in the CPU. The registers can be user accessible or inaccessible.

In computing, an arithmetic logic unit (ALU) is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers.

Examples of software are MS- Word, Excel, PowerPoint, Google Chrome, Photoshop, MySQL, etc.

Software is a collection of instructions, procedures, and documentation that performs different tasks on a computer system. Examples of software are MS- Word, Excel, PowerPoint, Google Chrome, Photoshop, MySQL, etc.

EEPROM stands for Electrically Erasable Programmable Read-Only Memory. EEPROM is a type of non-volatile primary memory and modified version of EPROM (Erasable Programmable Read-Only Memory) which uses electrical signals to erase and program the contents rather than UV signals which was used previously in EPROM.

Internal memory in the computer is the memory that is directly accessible by the processor without accessing the input-output channel of the computer. The internal memory is accessed by the processor over the system bus.

In computing, memory is a device or system that is used to store information for immediate use in a computer or related computer hardware and digital electronic devices

Secondary memory is a physical device for the permanent storage of programs and data(Hard disk, Compact disc, Flash drive, etc.).

Primary memory is made up of semiconductors, It is also divided into two types, Read-Only Memory (ROM) and Random Access Memory (RAM). Secondary memory is a physical device for the permanent storage of programs and data(Hard disk, Compact disc, Flash drive, etc.).

Memory which is used for permanent storage

Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed.

Volatile memory is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost.

A keyboard is one of the primary input devices used with a computer. Similar to an electric typewriter, a keyboard is composed of buttons used to create letters, numbers, and symbols, and perform additional functions.

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data.

A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS)

an output device is any piece of computer hardware that converts information into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment

punched card  is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery.

Special keys are found on keyboards often called multimedia keyboards.

Most companies use the PC keyboard with a total of 104 alphanumeric keys as a de facto standard

A&nbsp;daisy wheel printer&nbsp;is an early type of&nbsp;impact printer&nbsp;invented in&nbsp;1969&nbsp;by David S. Lee at Diablo Data Systems. The printer uses a metal or plastic disk containing each of the letters, numbers, and other characters it supports. When printing, the printer rotates the disk to each character and, using a hammer, strikes each character into an ink ribbon to create characters on paper.
