Classification of ROM


Answer:
The ROM (Read-only memory) is a type of non-volatile memory used in computers and other electronic devices.


Classification of ROM
ROMis divided into following types:

  • PROM
  • EPROM
  • EEPROM
PROM
PROM stands for Programmable Read Only Memory. This form of ROM is initially blank. The user or manufacturer can write data/program on it by using special devices. 

EPROM
    EPROM stands for Erasable Programmable Read Only Memory. This form of ROM is also initially blank. The user or manufacturer can write program or data on it by using special devices. 


 EEPROM
    EEPROM stands for Electrically Erasable Programmable Read Only Memory. This kind of ROM can be written or changed with the help of electrical devices. So data stored in this type of ROM chip can be easily modified.

Draw the basic organization of computer

Answer:                 The basic organization of computer__ Input Unit: ·          It accepts (or reads) instructions and data from outside. ·          It converts these instructions and data in computer acceptable form ·          It supplies the converted instructions and data to the computer system for further processing. Central Processing Unit (CPU): Control Unit: Control unit of a computer system manages and coordinates the operations of all other components of the computer system. Arithmetic Logic Unit(ALU): Arithmetic logic unit of a computer system is the place, where the actual executions of instruction, takes place during processing operation. Storage Unit: Primary Memory: It is volatile ( loses data on power dissipation). It is used to hold running program instruction, data, intermediate results, and results of ongoing processing of jobs. Secondary Memory: It i
