RAM (random access memory)

A type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers. There are two basic types of RAM: dynamic RAM (DRAM) and static RAM (SRAM).

Pronounced cash, a special highspeed storage mechanism. It can be either a reserved section of main memory or an independent highspeed storage device. Two types of caching are commonly used in personal computers: memory caching and disk caching. A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of highspeed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because most programs access the same data or instructions over and over. Disk caching works under the same principle as memory caching, but instead of using highspeed SRAM, a disk cache uses conventional main memory. When data is found in the cache, it is called a cache hit, and the effectiveness of a cache is judged by its hit rate.
A 6-byte address written in hexadecimal. The first 3 bytes of the address indicate the vendor or manufacturer of the physical network interface. The last 3 bytes make up a unique number assigned to that interface by the manufacturer. No two devices on the same network can have the same MAC address.
A set of conditions, events, and surroundings that don’t change. In theory, once understood, a static environment doesn’t offer new or surprising elements. A static IT environment is any system that is intended to remain unchanged by users and administrators. The goal is to prevent or at least reduce the possibility of a user implementing change that could result in reduced security or functional operation.
The term “computer forensics” was coined in 1991 in the first training session held by the International Association of Computer Specialists (IACIS) in Portland, Oregon. Since then, computer forensics has become a popular topic in computer security circles and in the legal community. Like any other forensic science, computer forensics deals with the application of law to a science. In this case, the science involved is computer science and some refer to it as Forensic Computer Science. Computer forensics has also been described as the autopsy of a computer hard disk drive because specialized software tools and techniques are required to analyze the various levels at which computer data is stored after the fact. Computer forensics deals with the preservation, identification, extraction, and documentation of computer evidence. The field is relatively new to the private sector, but it has been the mainstay of technologyrelated investigations and intelligence gathering in law enforcement and military agencies since the mid1980s. Like any other forensic science, computer forensics involves the use of sophisticated technology tools and procedures that must be followed to guarantee the accuracy of the preservation of evidence and the accuracy of results concerning computer evidence processing. Typically, computer forensic tools exist in the form of computer software.
