Differences DDR1 DDR2 DDR3

Maybe some of you still do not know what the difference of RAM DDR1 with DDR2 RAM, if you do not know yet I also learned just recently, to that for which you need to read this article carefully.difference of DDR1, DDR2, and DDR3 can be seen from the picture above ....The physical difference between types of memory on DDR with DDR2 the first type is the type of memory chip used. In DDR memory types, memory chip (IC) used on board is a memory module is a type TSOP (Thin Small-Outline Packege). The form is four square panjag with legs on the left and right. Rarely DDR memory module that uses a memory chip type BGA.
In the DDR2 memory type, the type of memory chip used is the type of BGA (Ball Grid Away). The form there are four long persei, those that square. But, unlike the TSOP type memory chips, the legs of the BGA type memory invisible to the eye as it is located under the chip and immediately and directly plugged into the memory module board.

Differences FAT16, FAT32, NTFS, and Swap. understanding of the kernel and boot sector


* FAT16

FAT16 was introduced by MS-DOS in 1981 (very old already). Initially, the system is designed to manage files on the floppy drive and changed several times so it is used to organize files on disk. The advantage is the FAT16 file system is compatible in almost any Operating System be it Windows 95/98/Me, OS / 2, Linux and even Unix. But behind it the biggest problem of FAT16 is having the capacity of a fixed number of clusters in the partition, so the bigger hard drive then the size of the cluster will be greater, meaning that the file no matter how small it would take 32 KB of disk. Another bad thing is FAT16 does not support compression, encryption and access control in the partition.

* FAT32

FAT32 system began in the know on Windows 95 SP2, and is a development of more than FAT16. The amount of FAT32 offers the ability to accommodate a larger cluster in the partition. It also developed the ability to drive is better than FAT16. However, FAT32 has a weakness that is not owned FAT16 is limited Operating System that can recognize FAT32. Unlike FAT16 which can be known by almost every Operating System, but it does not matter if you are running FAT32 on Windows XP because Windows XP does not matter what file system in use on the partition.
