Key Points

• Computer Terms	Description
  OMR	Optical mark recognition (OMR) is an electronic method of gathering human-handled data by identifying certain markings on a document or marking multiple-choice questions. Usually, the optical mark recognition process is achieved with the aid of a scanner that checks the transmission or reflection of light through the paper; places having markings will reflect less light than the blank paper, resulting in less contrasting reflectivity.
  MCIR	MICR (magnetic ink character recognition) is a technology invented in the 1950s that is used to verify the legitimacy or originality of checks and other paper documents.  Special ink, which is sensitive to magnetic fields, is used to print certain characters on the original documents.
  RAM	RAM, which stands for Random Access Memory, is a hardware device generally located on the motherboard of a computer and acts as an internal memory of the CPU. It allows the CPU to store programs and data temporarily.  It is the read-and-write memory of a computer, which means the information can be written to it as well as read from it.
  FIREWELL	A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet and prevents unauthorized access to a computer network.
