RAM is far faster than a hard drive.
RAM has no correlation to hard drive size. You could theoretically use a 320 GB hard drive with less than a MB of RAM.
The minimums are based on what you are. If you are a student 1GB RAM and 160GB Harddisk is the basic requirements. If you are a gaming person or a professional who wants fast computer then 2GB RAM and 250GB Harddisk is enough.
RAM means Random Access Memory. It store data temporaly. It called primary storing device. The two main forms of modern RAM are static RAM (SRAM) and dynamic RAM. Harddisk is the primary storing device within the computer. It can store data permanently (until you delete the data). It can retain data even after the computer itself "dies". Therefore, one harddisk can be switched to a different computer of similar size. An external harddisk can store huge amounts of data within a desktop unit. It can store data permanently (until you delete the data).
Those are located on the father board, next to the dipswitches and ribbonwires.

RAM stands for Random Access Memory. It is a temporary computer storage device, i.e. all data stored in RAM will be erased after the computer is switched off. All data to be processed is first copied into RAM. For example, when you start an application it is copied into the RAM from your harddisk. Similarly, if you enter any data into the computer it is sent to the RAM.
Components inside Computer (CPU) are Motherboard, Processor, RAM, Harddisk drive, Optical Media drive, SMPS etc.
Ha laga sakte ho. agar ram slot khali ho to. nahi to purana 256 MD ka ram hatana padega or fir 1gb ka ram lagana padega. 160gb hdd recognize hoga ya nai ye tumhare PC ke motherboard ke model or bios version pe depend karega.
Harddisk stores data for long term, it is also said as rom.
A (harddisk) is a hard drive that stores and provides quick access to large amounts of data.
The RAM is use in laptops are SD-RAM
