Thirteen Differences Between RAM and ROM

Sr # RAM ROM
1 RAM stands for Random Access Memory ROM stands for Read Only Memory.
2 RAM is a temporary memory. ROM is a permanent memory.
3 RAM is a volatile memory. ROM is a non volatile memory.
4 When computer is turned off, all data and programs are
erased from RAM. 
When computer is turned off, all data and programs are
retained in ROM.
5 RAM is a Read / Write memory. Data can be read and written
to RAM.
ROM is a read only memory. Data from ROM only can be read
and not written.
6 Data and programs in RAM can be changed. The contents of ROM cannot be changed.
7 Data or programs in RAM can be deleted. Contents of ROM cannot be deleted.
8 The instructions and data  are written (loaded) in RAM
at execution time, when computer is working.
The instructions in ROM are written at the time of
manufacturing.
9 RAM is used to load data and programs currently running. ROM contains the instructions that help the computer to
start-up and make it ready for work.
10 RAM is much faster than ROM. ROM is slower than RAM.
11 RAM has two main types: Static RAM and Dynamic RAM ROM has three types: PROM, EPROM and EEPROM
12 Physically RAM chip is larger than ROM chip. Physically ROM chip is smaller than RAM chip.

Explain different types of storage devices

Topic: Explain different types of storage devices in Computer systems Storage Devices Storage devices are used to store data and instructions permanently. Storage devices are also called secondary storage devices / backing storage devices / external storage devices or auxiliary storage devices. Examples of storage devices include Hard Disk, CD and DVD etc. Why Secondary Storage Devices are Used? Secondary storage devices are used because: Primary memory(RAM) is volatile and temporary. When computer is switched off, all data in ram is erased. Storage devices can store large amounts of data and instructions permanently whereas Primary memory has less capacity of storing data. Types Of Storage Devices There are three main types of storage devices:  Magnetic Tape   Magnetic Disk   Optical Disk   Flash Memory storage devices 1. Magnetic Tape Magnetic tape is the oldest storage device. It is made of plastic coated with m...

Explain Different Types Of Output Devices

Output devices Out put devices are used to display results of processing to the user. They perform the following functions:  Receive results from memory  Convert data into human readable form  Display results to the user Examples include: Monitor, printer, plotter, speaker, and multimedia projector. Different Types of Output Devices 1.    Monitor LCD Monitor CTR Monitor     Monitor is the most commonly used output device used to display results of processing. It has a TV like shape. Pictures on monitor are formed with picture elements called PIXEL. Monitors may be Monochrome that will display results in Black & White. Color Monitors are also available. They display results in multi colors. Monitor produces soft copy output. 2.    Printers Printers are used to produce hard copy out put. They print processing results on paper. Printers are divided into two main categories: · ...
