Answered| GRADED A+
What is MIS? - ANSWER-Interrelated components that interact with each other in order to achieve
specific goals
Information System - ANSWER-collects, stores, and processes data to provide useful, accurate, and
timely information typically within the context of an organization
Name of the first electronic airline reservation system? - ANSWER-American Airlines: system used to
store and retrieve information and conduct transactions related to airfare, hotel, and car rental
Sabre
History of Computers & first IT programmer - ANSWER-1822, Charles Babbage, mechanical computer
Ada Byron
What is the goal of the information system in an organization? - ANSWER-asses and evaluates business
problems and suggest solutions to help company achieve goals
CPU (Central Processing Unit) - ANSWER-The internal operating unit or "brain" of a computer
Works in conjunction with RAM, reads data and instructions from memory, and stores results of
computation in memory, loading and processing programs
Measured in hertz, 32-bit vs 64-bit
Motherboard - ANSWER-A circuit board that contains all of the computer system's main components
Holds CPU, RAM, OS
- allows all parts of your computer to receive power and communicate with one another
Cards - ANSWER-removable circuit boards that are inserted into slots in the motherboard to expand its
capabilities
,USB Drives - ANSWER-a removable data storage devices that includes flash memory
RAM (Random Access Memory) - ANSWER-- a temporary holding area for data, application program
instructions, and the operating system
- Most RAM is volatile, meaning it needs electrical power to hold data
ROM (Read-only memory) - ANSWER-It is non-volatile memory. It is also a storage medium that is used
with computers and other electronic devices. As the name indicates, data stored in it may only be read.
Permanent Storage.
How do computers represent information? How does the monitor represent information? - ANSWER-1)
CPU transfers data from storage disk to RAM
2) CPU moves programs or instructions from RAM to CPU via data channel
3) we input commands/ instructions and it outputs via monitor or printer
Basic Networking, Internet as a WAN - ANSWER-Internet is collection of WANS (Wide Area Network)
Secondary Memory - ANSWER-external and permanent, floppy disks, magnetic (hard) disk, optical disks
How each of the computer component specifications are described? - ANSWER-1 byte= 8 bits= 1 letter
or number
1 kilobyte= one thousand bytes= 1 typewritten page
1 megabyte= one million bytes= 1 digital photo
1 gigabyte= one billion bytes= 1 DVD movie
1 terabyte= one trillion bytes bytes
1 petabyte= 2^50 bytes
1 exabyte= 2^60 bytes
1 zettabyte= 2^70 bytes= estimated total amount of data transmitted
, Data capacity specified by bytes and CPU, speed expressed in cycles called hertz
Megahertz (MHz) - ANSWER-The number of millions of CPU cycles per second
Gigahertz (GHz) - ANSWER-The number of billions of CPU cycles per second
Magnetic Storage Devices - ANSWER-Include the internal hard disk as well as floppy disks, which are no
longer widely used
contains platters and their associated read-write heads
Optical Storage Devices - ANSWER-A form of secondary storage in which a laser reads the surface of a
reflective plastic platter
CD, DVD, etc, represents data as a microscopic light and dark spots on the disc surface
Solid State Drive - ANSWER-a storage device that typically uses flash memory to store data, instructions,
and information
used as a sub for hard disks
USB Flash Drive - ANSWER-a portable storage device that plugs directly into a computers system unit
using a built in USB connector
How the computer works - ANSWER-Operating system: provides a common set of controls for managing
computer hardware, making it easier for users to interact with computers and for programmers to write
application software
Microsoft, windows, macOS, Linux
Memory swapping
