RAM

Introduction: We all know RAM places a major role in increasing the speed of processing.

RAM is referred as Random Access Memory. It stores data temporarily; it is a volatile memory that erases all the data contained when the computer is switched off. When system is on the major files i.e system files are stored in the ram for quick processing when needed. The background programs like antivirus and many other are stored in RAM for quick processing. This makes the processing slower for other applications as huge amount of memory is allocated for such programs. So by inserting the RAM in DIMM modules we can extend our primary memory. It depend upon number of DIMM modules.

In Ram the data is randomly stored that why it is called RAM, as the data is accessed by the processor randomly.

Ram is different from ROM as ROM is read only Memory. There are mainly two types of RAM

· Static RAM (SRAM)

· Dynamic RAM (DRAM)

Static RAM is used mainly where high speed memory is needed as they are faster.

Ex:- L2 cache memory of CPU.

The cost of SRAM is more when compared to DRAM.

Dynamic RAM is most commonly used memory in the computer as it is slower than SRAM and less in cost.

Working:

RAM stores data for shorter period of time and discards it once it is not required by the processor or when the computer is switched off. It cannot store permanently so we require hard drives to store our data permanently.

Among the static and Dynamic RAM DRAM is the most commonly used. Its sub types are as follows…..

SDRAM- Synchronized Dynamic RAM, here the speed of RAM is synchronized with the CPU clock pulse. This helps in pipelining the read and write requests which enables SDRAM to accept certain commands when processing other.

DDR- DDR stands for Double Data Rate RAM which is an enhanced version of SDRAM, as the name suggests this memory doubles the bandwidth of the SDRAM.

DDR2- It is the second generation of DDR which uses low voltages and have prominent performance. It works on the principle of Differential Signaling.

DDR3- DDR3 is the third generation and improvised version of DDR2, due to the factors like Increased clock speed and higher bandwidth, low voltages and power consumption.

DDR2 are most popularly used in these days due to speeds from 533 – 800 MHZ.

CORRUPTION - the cause, its effect, the types and the solution for eliminating it

WHAT IS CORRUPTION?
Misuse of entrusted funds and power for private/individual gain is termed as Corruption. It is generally described as cheating, bribing or doing other unethical things in order to get personal benefit or profit. It includes giving or accepting bribes, offering inappropriate gifts, manipulating elections, swallowing funds allotted by the Government/Employer for personal gain, laundering money, cheating investors in various schemes etc.,
Corruption is universal. It exists in all developed and developing countries in varying degrees, both in the public and private sectors, as well as in non-profit and charitable institutions. Corruption has its own grades and they range from liquor, women and social influence and finally liquid cash. Many lives have been ruined from bad vices like gambling, drinking, betting etc., and corrupt people are using these devices to ruin their rivals. Corruption is a major issue for most of the countries which adversely affe…

Homeopathy medicines - A Guide for the Old, Poor and the Needy people

The last stage in human life is Old age. At this stage old people will encounter negligence from others including their families in some worst cases. Not only this, they will develop self negligence. Due to Competitiveness, tension due to pressure of work, spending leisure time on viewing TV, Children's education etc., youth also neglects them. Though the youth have love and affection towards them , they are not spending sufficient time as expected  by the old people due to the  above reasons. Youth working in foreign countries is also one of the reasons.


As a  result, old  people  are getting mental imbalance. They feel  that their vast experience in dealing things and  their sacrifices  for the family have no recognition by their kith and kin.Neglected presence of the old  people in taking decisions in important family matters will lead them to distress and self non-attention over the diseases from which they suffer. As a result they develop a tendency  "What for we are to l…

Tapatraya (3 Cravings) of Humans and the suitable methods to suffice them

Tapatraya in Sanskrit, means 'The 3 Cravings (Anxieties)' of the Human Life. Trying for a thing or for a purpose with undue longing and anxiety is generally called as Tapatraya (Craving). This is the common man’s view. But spiritually this has got a different meaning, a meaning in true sense.

These three kinds of cravings termed as Tapatraya are  - 1. Aadhi Bhouthika (Physical), 2. Aadhi Dyvika (Mental), and 3. Adhyatmika (Spiritual).

The explanation of these three may differ from one school of thought to the other. But let us think according to our view.
