Answer:
a. True
Explanation:
A computer can be defined as an electronic device that is capable of receiving of data in its raw form as input and processes these data into information that could be used by an end user. Computers can be classified on the basis of their size and capacity as follows;
I. Supercomputers.
II. Mainframe computers.
III. Mini computers.
IV. Micro computers.
Mainframe computers were developed and introduced in the early 1950s.
Mainframe computers are specifically designed to be used for performing multi-programming because they are high-performance computers with the ability to handle multiple users. As a result, it simply means that mainframe computers can be used to effectively and efficiently perform the work of over one hundred (100) users at a time on the computer. Some examples of mainframe computers include the following; IBM Es000 series, CDC 6600 and ICL39 Series.
Furthermore, mainframe computers are mostly or commonly used by large companies, business firms or governmental institutions for performing various complex tasks such as census, financial transactions, e-commerce, data sequencing, enterprise resource planning, etc.
Answer: A user authentication
A Deceleration device.
A rope, wire rope, or strap with connectors at each end for connecting the 5 point body harness to a lifeline, or anchorage.
Look under OSHA Flashcards on Quizlet and..
OSHA: Fall Protection in Construction, Subpart M and just past that area in the document.
This is from that document on page 13 and 14:
Fall Restraint Systems: While fall restraint systems are not
mentioned in Subpart M, OSHA
recognizes a fall restraint system as
a means of prevention. The system,
if properly used, tethers a worker
in a manner that will not allow a
fall of any distance. This system is
comprised of a body belt or body
harness, an anchorage, connectors,
and other necessary equipment.
Other components typically include

a lanyard, a lifeline, and other devices. For a restraint system
to work, the anchorage must be strong enough to prevent the
worker from moving past the point where the system is fully
extended, including an appropriate safety factor.
*In a November 2, 1995 interpretation letter to Mr. Dennis
Gilmore, OSHA suggested that, at a minimum, a fall restraint
system must have the capacity to withstand at least 3,000
pounds or twice the maximum expected force that is needed
to restrain the person from exposure to the fall hazard. In
determining this force, consideration should be given to
site-specific factors such as the force generated by a person
(including his/her tools, equipment, and materials) walking,
slipping, tripping, leaning, or sliding along the work surface.
