processing programs that require large-capacity memory at this time will appear stretched, resulting in a bottleneck of operational efficiency. The 64-bit processor in theory can reach 18 million TB,1TB equals 1024GB,1GB equals 1024MB, so 64-bit processor can completely solve the bottleneck phenomenon of 32-bit computing system, fast people, for those who require multi-processor scalability, 64-bit processors deliver superior performance for larger a
, select the Apply to this folder, subfolders, and Files check box, and then click OK. Compare Windows folder compression before and after space. Before compression space is: 1.19GB, compressed 865MB, means that after compression, the disk can be more than 325MB available space.
Attention:
1. Compression is the compression of disk folders, subfolders, and files to reduce disk space consumption, while the total capacity of the disk is not increased.
2. Disk compression only compresses local di

InnoDB is included in the MySQL binary distribution by default. Windows Essentials Installer makes InnoDB the default table for MySQL on Windows.
InnoDB is used in many large database sites that require high performance. The famous Internet news site slashdot.org runs on the InnoDB. Mytrix, Inc. stores more than
Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB?
Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese character requires two bytes of storage space,

From the above information can be seen. The current system has a 1TB disk SDA, a total of 5 partition Sda1-sda5, where the partition Sda3 for the swap partition, SDA4 for the extended partition. It is important to note that the extended partition cannot be used directly, and it needs to continue partitioning the logical partition under the extended partition. \

today a lot of notebooks (including tablets) no matter how big the hard drive, but the manufacturer only left us a C disk, yes, a 500GB or even 1TB of C disk! In the event of a system failure, the data on the hard drive will be compromised. So, what's a good way to cut a huge C disk into more partitions?
Seeing this, it is estimated that many children's shoes will think of professional tools such as "Partition Assistant", or repartition when installi
First, capacity
The size of the mobile hard disk capacity is the first choice for many people, usually in GB or TB units, the current market mainstream mobile hard disk capacity has 320GB, 500GB, 1TB, 2TB and so on. The size of the capacity is directly related to the user's storage needs, the choice of mobile hard disk capacity, should be based on their actual needs and product price to decide.
