MBA 703-Module 2 UPDATED ACTUAL Questions and
CORRECT Answers
Hardwire Tangible, physical portion of an information system/computing device
Digital devices processes electronic signals into discrete values,
of which there can be two or more
Many electronic devices process signals into two discrete
values,
typically known as Binary. These values are represented
as either
a one ("on") or a zero ("off").
Bit What each one or zero is referred to
Byte A group of 8 bits
Word size The number of bits that can be processed by a computer's processor at one time
What numbering system do computers use? Base 2.
What is the lowest level of data storage? Bit (stored as either one or zero)
What is the highest number that can be sent in a byte? 225, which is 11111111
What are the basic components of a computer? A Central Processing Unit (CPU), memory, circuit
board, storage, and input/output devices
Central Processing Unit (CPU) It can be thought of as the "brains" of the device. The CPU carries out the
commands sent to it by the software and returns results to be acted upon.
, Who are the two primary manufacturers of CPU's? Intel and Advanced Micro Devices (AMD).
Hertz How the speed ("clock time") of a CPU. A hertz is
defined as one cycle per second
Kilohertz one thousand cycles per second
Megahertz
Moore's Law the observation that computing power roughly doubles every two years. "faster,
cheaper," phenomenon. hip performance per dollar doubles every eighteen
months (Moore's original paper assumed two years, but many sources today refer
to the eighteen-month figure, so we'll stick with that).
Huang's Law an observation in computer science and engineering that advancements in
graphics processing units (GPU) are growing at a rate much faster than with
traditional central processing units (CPU).
Motherboard the main circuit board of the computer. The
CPU, memory, and storage components, among other things, all connect into the
motherboard.
Random Access Memory (RAM) Computer location where instructions and data are stored on a temporary basis.
(working memory) This memory is volatile. (can transfer data much faster than the
hard disk) Chip based memory
Hard Disk Drive Long-term data storage and is considered non-volatile
Solid State Drive (SSD) performs the same function as a hard disk,
namely long-term storage. Instead of spinning disks, the SSD uses flash memory
that incorporates EEPROM (Electrically Erasable Programmable Read Only
Memory) chips, which is much faster.
How has hardware improved speed? by giving the electrons shorter distances to travel
in completing a circuit.
Integrated circuits engineers have constantly worked to figure out how to shrink these circuits and
put more and more circuits onto the same chip
QuickPath Interconnect (QPI) a technique which minimizes the
processor's need to communicate directly with RAM or the hard drive. Instead,
the CPU contains a cache of frequently used data for a particular program. An
algorithm evaluates a program's data usage and determines which data should be
temporarily stored in
the cache.
What are the components that contribute to the speed of CPU, the motherboard, RAM, and the
a personal computer? hard disk.
