If the write line is low, the system transfers data from the CPU to memory. The main memory is the central storage unit in a computer system. It is a relatively large and fast memory used to store programs and data during the computer operation. The principal technology used for the main memory is based on semiconductor integrated circuit.

Unit 4 Microelectronics
Integrated circuits are small, light, rugged, and reliable. They require less power and lower voltages than equivalent macroscopic circuits; consequently they operate at lower temperatures, and individual components may be close together without exceeding the operating temperature limit. Relatively little stray capacitance and short time delays are produced because of the short interconnections between the individual components in IC. Maintenance is simplified because if a component of the IC fails the complete IC is usually replaced. Mass production techniques of plane technology have reduced the cost of many IC so that they are almost as inexpensive as a single transistor. Eventually most conventional circuits will be replaced by IC.
［2］ The reduction in power dissipation is particularly important where a complex circuit is to be concentrated into a small space. The problem of extracting the heat generated in the circuit may then be a difficult one.

在分层结构中，分布式系统的模型可以用来为每一层设 计协议。只有关于系统的假设和待解决的问题在层与层 之间相互不同。
For example, in the data link layer the possibility of transmission errors is considered, but in the higher level protocols this possibility is ignored, in the network layer it is assumed that the processes are not all directly connected by a channel (otherwise the routing problem would be trivial).
同时由于在下面的网络中存在中间计算机的可能 性，信息可能被丢失或复制。 (正如转播的结果)
A next layer in the hierarchy, the transport layer, serves to deal with these problems. The session layer concerns the problem of reliably opening and closing connections between processes in the network.
Each layer (or level) consists of protocols that use functions of the lower layers and provide services to the higher layers.
每层 (或级)由协议组成，这些协议使用较低层的功能并 且为较高层提供服务。
