Personal computer hardware and om-nanotech best ram manufacturer and supplier in india

A personal Ram manufacturer  computer is made up of multiple physical components of computer hardware, upon which can be installed a system software called operating system and a multitude of software applications to perform the operator's desired functions.

Though a PC comes in many different forms, a typical personal computer consists of a case or chassis in a tower shape (desktop), containing components such as a motherboard.

Motherboard



The motherboard is the main component inside the case. It is a large rectangular board with integrated circuitry that connects the rest of the parts of the computer including the CPU, the BEST RAM MANUFACTURER AND SUPPLIER, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots.

Components directly attached to the motherboard include:

    * The central processing unit (CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the "brain" of the computer. It is usually cooled by a heat sink and fan.
    * The chip set mediates communication between the CPU and the other components of the system, including main memory.
    * RAM (Random Access Memory) stores resident part of the current running OS (OS core and so on) and all running processes (application parts, using CPU or input/output (I/O) channels or waiting for CPU or I/O channels).
    * The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by operating system drivers.
A power supply unit (PSU) converts alternating current (AC) electric power to low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits. Power supply units used in computers are nearly always switch mode power supplies (SMPS). The SMPS provides regulated direct current power at the several voltages required by the motherboard and accessories such as disk drives and cooling fans.Ram Manufacturer and supplier

Memory Cards – Useful to Store Personal Stuffs


Memory Cards – Useful to Store Personal Stuffs
Summary – What are memory cards all about? Considering modern needs of data storage, one of the nice ways of storing personal stuffs is to make use of such cards which are available in different types in the market.
Electronic products like laptop, desktop and handsets come with the feature of storage capacity. Memory cards are found in these products which can help one to store desired files either any music file, images, video clips or other personal stuffsMemory Cards.
This is the fact that we have varieties of everything in the market. We can compare things before taking final decision of purchasing them. In the same way, one can also go for the comparison of storage cards before bringing them to home.
As far as types of such cards are concerned, they are available in three different kinds like:
Memory Stick
Sony is the first company who have launched this removable flash storage card format in the year 1998. The family of family stick comes with different versions like Memory Stick Pro and Memory Stick Duo.DDR1 Ram ,Both versions are known to come with faster speed of file transfers.
Multi Media Card
MMC was introduced in the year 1997 by Siemens AG and SanDisk Corporation. That time, the media card was considered the smallest card meant for the storage of files with fast speed. One would be surprised to know that microSD card is based on MultiMediaCard e as it comes with same form and factor. The difference is that microSD card comes with more thickness and a write protection chip as compared to MMC.
As far as speed is concerned, the speed of MMC is found less as compared to other card forms. Earlier, the speed was noticed as 2.5 MB/sec and the latest speed one will found up to 52 MB/sec. There are certain forms of MMC like RS-MMC, DV RS-MMC, etc.,
Secure Digital Card
SD or Secure Digital card is the last and the most advanced type of storage cards available till date. Most commonly used storage cards is SD cards and one can easily found them in digital cameras and several other electronic devices which support file transfer. More than flash storage cards, slots of SD cards can be brought into use.
The Secure Digital In & Out, the expansion modules that one will found in the SD Memory Card's form factor. SDIO modules can be inserted in the slot and can be used for numerous functions like GPS receivers, Bluetooth adapters, TV tuners, digital cameras, etc.
Other types of storage cards like mircoSD and miniSD cards are in use. ddr ram memory
And all these forms of memory cards come with the capable features of storing desired stuffs of the user. In short, one has wide options in the memory card industry to get the one as per need and desire.

what is ram?


Pronounced ramm, acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers,memory modules .

There are two different types of RAM: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The two types differ in the technology they use to hold data, with DRAM being the more common type. In terms of speed, SRAM is faster. DRAM needs to be refreshed thousands of times per second while SRAM does not need to be refreshed, which is what makes it faster than DRAM. DRAM supports access times of about 60 nanoseconds, SRAM can give access times as low as 10 nanoseconds. Despite SRAM being faster, it's not as commonly used as DRAM because it's so much more expensive. Both types of RAM manufacturer are volatile, meaning that they lose their contents when the power is turned off.
In common usage, the term RAM is synonymous with main memory, the memory available to programs. For example, a computer with 8MB RAM has approximately 8 million bytes of memory that programs can use. In contrast, ROM (read-only memory) refers to special memory used to store programs that boot the computer and perform diagnostics. Most personal computers have a small amount of ROM (a few thousand bytes). In fact, both types of memory (ROM and RAM)Memory Cards allow random access. To be precise, therefore, RAM should be referred to as read/write RAM and ROM as read-only RAM.

What is the BEST RAM Manufacturer??


DDR RAM memory

DDR RAM memory or DDR SDRAM (Double-Data-Rate Synchronous Dynamic Random Access Memory is an extremely fast computer memory. The clock signal is useful in managing the communication between digital circuits. The DDR RAM memory transfers two times the data in the same time through its clock signal.We are leading manufacturer and supplier of Computer Memory .
How is this achieved? The clock signal synchronizes communication. When the clock signal rises or falls, the digital circuits tend to respond back. The main difference between the SDRAM and DDR memory is the manner in which the clock signal is being used for exchange of data. The SDRAM memory chips were being used to transfer data by responding to the rising edge of the signal. During this time the SDRAM transfers 64 bits of data at a time to the CPU. The DDR RAM is twice faster than the SDRAM. It responds both to the rising and falling edges of the clock signal in order to transfer data without changing the clock frequency.
The FSB or the front side bus which is a two-way data channel and the RAM speed work together in a computer system. Information from the CPU or the central processing unit is sent by the FSB to the motherboard and other components like the RAM hard drives, BIOS chips and PCI slots. This makes a computer system work like a 266MHz machine with a FSB of 133MHz that is operating a DDR1 SDRAM.
The DDR RAM memory can only operate as fast as the motherboard allows it to do so. Though it is available in a number of speeds, it is a sheer waste of money if such a version is installed that works faster than the motherboard.
There is one notch on the connecting side of the DDR memory module,ddr memory and there are two notches that get attached to the PC mother board and hold it in place. The DDR RAM is available in a double sided or single sided chip configuration. There are 184 pins in a desktop DDR whereas a SDRAM has 168 pins.
There are three kinds of DDR RAM. The DDR or DDR1 come with a range of clock speeds from 100Mhz to 200 Mhz. Superseding this is the DDR2 that has 240-pin with quadrupled speed of 266Mhz. The DDR3 has a 240-pin module that not only uses less of power but also has a speed that is eight times faster than SDRAM.
