求问大神8g内存卡等于多少mb3个回答散淡之人88g内存卡等于多少1GB=1024MB, 8GB=2MB 硬件制造商计算地方是是的如下：1GB=1000MB, 8GB=0MB理论上是8×1024，但一般厂家的算法是8×1000，内存卡本身还占用一部分空间，所以实际可使用的容量是7G多
贾靖柔厂商计算容量的方法和计算机的不同，厂商计算的方法是1000KB=1M，而计算机计算的方法是1024KB=1M.所以按照计算机标准。8g=bit,由于1G=1024M，1M=1024K，1k=*
卡实际容量为：bit/24=7.45G
所以8G内卡在计算机中实际容量为7.45G。
1G=1024M。7.45G=7.45*M。
一切皆有可能_2358理论上是8×1024，但一般厂家的算法是8×1000，内存卡本身还占用一部分空间，所以实际可使用的容量是7G多

内存卡同是u3一个90mb/s一个95mb/s差别大吗
我有更好的答案
如果是手机参数如果真实,基本感觉不出来差异,装到相机或摄像机上使用
我是装摄像机的。价格相差1/3，有必要上95mb的吗
参数真实的话,没必要.
帮忙看下这两个，一个速度c10一个80x
这个看不出来。网上所说非所得太多了。
你的摄像机用的是小卡？
买大卡比较好。
因为有时会放手机上。所以就买小的。
速度接近，差别不多。

MongoDB的一些知识
mongodb的Windows客户端：MongoChef
mongochef-x64.msi mongodb管理工具
连接复制集和分片集群都可以& ，而且不崩溃
需要在Windows上安装mongodb，调用mongo.exe
角色分两种：1、针对实例上所有数据库&& 有5种权限2、针对单个数据库& 有3种权限db.createUser({user:"lyhabcd",pwd:"123456",roles:[{role:"dbOwner",db:"testdb"}]})&& //针对所有数据库db:"admin"& 针对单个数据库 db:"dbname"
用户权限控制
实例上的所有用户都保存在admin数据库下的system.users 集合里

官方推荐副本集的成员数量为奇数，最多12个副本集节点，最多7个节点参与选举。最多12个副本集节点是因为没必要一份数据复制那么多份，备份太多反而增加了网络负载和拖慢了集群性能；而最多7个节点参与选举是因为内部选举机制节点数量太多就会导致1分钟内还选不出主节点，凡事只要适当就好相关文章http://www.lanceyan.com/tech/mongodb/mongodb_repset1.htmlhttp://www.lanceyan.com/tech/arch/mongodb_shard1.htmlhttp://www.lanceyan.com/tech/mongodb_repset2.htmlhttp://blog.nosqlfan.com/html/4139.html&& （Bully 算法）心跳 综上所述，整个集群需要保持一定的通信才能知道哪些节点活着哪些节点挂掉。mongodb节点会向副本集中的其他节点每两秒就会发送一次pings包，如果其他节点在10秒钟之内没有返回就标示为不能访问。每个节点内部都会维护一个状态映射表，表明当前每个节点是什么角色、日志时间戳等关键信息。如果是主节点，除了维护映射表外还需要检查自己能否和集群中内大部分节点通讯，如果不能则把自己降级为secondary只读节点。同步副本集同步分为初始化同步和keep复制。初始化同步指全量从主节点同步数据，如果主节点数据量比较大同步时间会比较长。而keep复制指初始化同步过后，节点之间的实时同步一般是增量同步。初始化同步不只是在第一次才会被触发，有以下两种情况会触发：secondary第一次加入，这个是肯定的。secondary落后的数据量超过了oplog的大小，这样也会被全量复制。那什么是oplog的大小？前面说过oplog保存了数据的操作记录，secondary复制oplog并把里面的操作在secondary执行一遍。但是oplog也是mongodb的一个集合，保存在local.oplog.rs里，但是这个oplog是一个capped collection也就是固定大小的集合，新数据加入超过集合的大小会覆盖。所以这里需要注意，跨IDC的复制要设置合适的oplogSize，避免在生产环境经常产生全量复制。oplogSize 可以通过&oplogSize设置大小，对于linux 和windows 64位，oplog size默认为剩余磁盘空间的5%。同步也并非只能从主节点同步，假设集群中3个节点，节点1是主节点在IDC1，节点2、节点3在IDC2，初始化节点2、节点3会从节点1同步数据。后面节点2、节点3会使用就近原则从当前IDC的副本集中进行复制，只要有一个节点从IDC1的节点1复制数据。设置同步还要注意以下几点：secondary不会从delayed和hidden成员上复制数据。只要是需要同步，两个成员的buildindexes必须要相同无论是否是true和false。buildindexes主要用来设置是否这个节点的数据用于查询，默认为true。如果同步操作30秒都没有反应，则会重新选择一个节点进行同步。
增删节点: 后台有两个deamon做 chunk的split , 和 shard之前的balance When removing a shard, the balancer migrates all chunks from a shard to other shards. After migrating all data and updating the meta data, you can safely remove the shard （这里的意思，必须要等搬迁完毕，不然数据就会丢失）这个是因为片键的设置，文章中是为了做demo用的设置，这是不太好的方式，最好不要用自增id做片键，因为会出现数据热点，可以选用objectid相关文章http://www.lanceyan.com/tech/arch/mongodb_shard1.html
