1. The document discusses different types of computer memory and storage devices. It describes RAM, ROM, SRAM, and DRAM memory types and how RAM is used for temporary data storage.
2. Storage devices discussed include floppy disks, hard disks, magnetic tape, CDs, DVDs, and other optical discs. Floppy disks contain flexible plastic disks and were used to transfer small amounts of data between computers.
3. Hard disks differ in that they contain rigid metal platters that spin faster than floppy disks and are sealed inside the computer. Magnetic tape is cheaper for storing files and documents and transferring information between computers.
RAM(Random Access memory) is a volatile memory.RAM is our working memory storage. All the data, which the PC uses and works with during operation, are stored here. Data are stored on drives, typically the hard drive. However, for the CPU to work with those data, they must be read into the working memory storage, which is made up of RAM chips.
Historical review:
Back in the 80's, PC's were equipped with RAM in quantities of 64 KB, 256 KB, 512 KB and finally 1 MB. Around 1990, advanced operating systems, like Windows, appeared on the market, that started the RAM race. The PC needed more and more RAM. That worked fine with the 386 processor, which could address larger amount of RAM. The first Windows operated PC's could address 2 MB RAM, but 4 MB soon became the standard. The race has continued through the 90's, as RAM prices have dropped dramatically. Today it would be foolish to consider less than 64 MB RAM in a PC. The OS like windows Xp requires better than this.
Primary Memory: RAM, ROM and their TypesHem Pokhrel
Random Access Memory and Read Only Memory along with their types:
Content includes basic introduction of SRAM, DRAM, NvRAM, Masked ROM, PROM, EPROM, EEPROM
Primary storage, also known as main storage or memory, is the area in a computer in which data is stored for quick access by the computer's processor. The terms random access memory (RAM) and memory are often as synonyms for primary or main storage

RAM (Random access memory) is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor.
short note for basic students | Types of Memory, ram, rom and storage.
- memory types.
- types of ROMs (Read Only Memory)
- Advantages of ROM
- Ram(random access memory)
- storage device
This slide provide the introduction to the computer , instruction formats and their execution, Common Bus System , Instruction Cycle, Hardwired Control Unit and I/O operation and handling of interrupt
Primary memory (main memory)
complete knowledge about main memory Ram Rom and its kinds
with history and pictures
try it to believe it
Main memory refers to physical memory that is internal to the computer
Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained inside the case of a computer.
Presentation about Operating System.
including file management.process management,multitasking,different kind of operating system,some popular operating system

Without a significant amount of memory, a computer would merely be able to perform fixed operations and immediately output the result without storing them therefore some kind of memory is placed in the computer to store instructions for processor and data to be processed and also the output results for future use.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
3. Memory devices:
A memory is just like a human brain. It is used to store
data and instruction. Computer memory is the storage
space in computer where data is to be processed and
instructions required for processing are stored
The memory is divided into large number of small parts.
Each part is called a cell. Each location or cell has a
unique address which varies from zero to memory size
minus one.

5. Static RAM
(SRAM)
Its is faster and more
reliable than DRAM. Its
chips utilize less power
the SRAM Chips is
more expensive then
DRAM chips
Dynamic RAM
(DRAM)
DRAM is used for most
system memory
because it is cheap and
small. All DRAMs are
made up of memory
cells.
RAM
RAM stands for Random Access Memory . RAM is also called main memory .
its consists of memory chips on the mother board. It is read/write memory. Data
and instructions are store in it temporarily
5
6. PROM (Programmable Read Only Memory).
PROM is blank chip which a programmer can write program or data using
special device. If any error in data in PROM than we can not erase the data.
EPROM (Erasable Programmable Read Only Memory).
The data written in EPROM chip can be erased by using special device and
ultra –violate rays .
EEPROM (Electrically Erasable Programmable Read Only Memory)’
This kind ROM can be written or changed with the help of electrical devices. So
data in this type of ROM chip can be easily modified data
ROM stands for Read Only Memory. The memory from which we
can only read but cannot write on it. This type of memory is non-
volatile. The information is stored permanently in such memories
during manufacture

7. A storage device may hold information, process information, or both. A device that only holds
information is a recording medium. Devices that process information (data storage equipment) may
either access a separate portable (removable) recording medium or a permanent component to store
or retrieve data.

9. FLOPPY
DISK:
Floppy means soft. Its also
called floppies and diskette.
Its made by flexible plastic.
Its enclosed in cardboard
jacket. And now use for
transfer small data from one
computer to another.

HARD
DISK:
1. Hard disks are sealed in a
chamber
2. Hard disk consists of a rigid
metal platter (usually aluminum)
rather than flexible Mylar.
3.Hard disk spin between 3600 rpm
and 7200 rpm compared to a
diskette 300 rpm.

MAGENETIC TAPE:
A diskette contains a single flat piece of plastic (the
disk) coated with iron Oxide enclosed in vinyl or
plastic cover. Its also cheaper. Its used for store files
and documents. And also use for transfer information
from one computer to another.
