Log files store data and mapping locations in a computer’s CPU, including execution instructions for software programs. Decoders extract data from the registry, and log files use static or dynamic RAM with different cycle and access times.
A log file is a storage medium within a computer’s central processing unit (CPU). Computer registry files contain data bits and mapping locations. These locations specify certain addresses which are input components of a log file. Other inputs include data, a read and write function, and an execute function.
When a user installs a program on a computer, that software application writes a log file to the CPU. Most software programs will contain more than one file. These files contain execution instructions that the CPU follows when the user launches and uses the application. A log file also lets the CPU know where the program is and what data is needed to perform certain functions.
Decoders are part of a log file. When data is pulled from a registry, the computer’s hard drive references the bits contained in the file. Part of the extraction process involves reading and deciphering the data bits contained in the register. Once a program completes a function, it can write code or a message indicating the results of the operation.
Log files use one of two memory technologies. The former is known as static random access memory or SRAM. With static random access memory there are several bits of memory that are labeled according to binary code. The state of each memory bit is labeled with a zero or one, indicating an active or inactive state.
A second type of register memory is dynamic random access memory or DRAM. Each memory section contains a capacitor and a transistor. Data values equate to several charges and must be constantly updated by the memory chip. The update or “refresh” typically takes up to 2% of the total processing time.
There are two components to the memory chip’s ability to process data. They include cycle and access time. Cycle time is the lowest amount of time that occurs between requests for data. Access time is the amount of seconds or minutes it takes for the CPU to request data from a log file and the time it takes to actually receive that information.
While SRAM is usually used with memory caches, the cycle time and access time are the same. With DRAM technology, the cycle time is typically longer than its access time. This is because memory reads or extracts involve a process of destroying and rewriting.
