Module 4 Flashcards
What are the types of user interfaces
Command driven interface
Menu driven interface
Graphical interface (GUI)
Command driven interface
Type commands
Complicated for the average user
Menu driven interfsce
User chooses the command from the menu
Not easy for everyone
Graphical interface (GUI)
Displays graphics and uses pointed and click technology
User friendly
Whats is plug and play
Not a driver
It is a software and hardware standard designed to facilitate installation of a new piece of hardware in computers
It does so by including the OS
How to deal with errors in the boot process
Go in safe mode
Uninstall faulty program
System back up
Creates a copy of your drive to another hard drive
What are the operating system functions
Provides an interface
Manages the CPU
Manages the hardware
Coordinates the application software with the CPU
What is the operating system (OS)
Controls how your computer system functions and manages the following:
Hardware
Processor
Peripheral devices
Memory
Responsible for task management
Provides whatever interface to the user
What provides an organization structure to your computer
File management
What happens during a system backup
Creates a copy of your drive to another hard drive
What is a system restore
Restores the system to a specific date in which you did the system back up
It is like when you die in a video game and you restart there where you saved
What are the four basic steps of the boot process
- The basic input/output system (BIOS) is activated by powering on the CPU
- BIOS checks that all attached devices are in place and functional
- Operating system (OS) is loaded into RAM
- Configuration and costumization systems are checked
What is a multi user operating system
A network of operating systems
Enables more than one computer system at a time
Juggles requests from several computers at the same time
Give examples of multi user operating systems
Linux
Unix
Win server 2008
MAC Os X
IBM 1
Z/OS
What are the operating system categories
Realtime OS
Multi user OS
Single user multitask OS
Single user single task OS
Real time operating system
Embedded systems
Ex: found in measure instruements
Mutli user OS
Network O
Ex: MS Windows server OS
Single user (multitask) OS
Ex: Apple Mac OS
Win 7
Single user (single task) OS
Ex: mS-DOS
Task scheduler
Run automatically a program that defrag or back up your computer hard drive
Disk defragmenter
Reorganize files in a hard drive to improve speed
What is the virtual memory
memory management capability of an operating system (OS)
uses hardware and software to allow a computer to compensate for physical memory shortages
temporarily transferring data from random access memory (RAM) to disk storage
What are the utility programs
Backup
Security
Diagnóstic
Recovery
Describe a file path
Drive: C://
Primary folder: user/
Subfolder: username/doc/spring
Filename: boyyy
Extension: docx
What is MS windows
Increased functionality
User friendly
Improved internet capabilities
Enhanced privacy and security
Mutli user OS
Windows 10 has latest version
What does the operating system contain
Not is functions
But like its architecture
More than 4GB of RAM
64 but version of windows
What translates the specialized commands of a device to the OS in a way that the latter can understand it?
Can also be vice versa
Device driver
What is Linux
Open source operating system
Based on HNIX
Stable system
Download for free
Can be tweaked
Runs on PC, Ipod and Laptop
Gaming systems
What is Unix
Mutliuser and mutlitasking OS
Used for mainframes as network OS
Whats is a real time operating system
Machine that performs repeotfve tasks in a short period of time
Automobiles
Printers
VOIP phones
Medical devices
Robotic equipment
Program takes out redundancies in a file to reduce the file size
Ex: zipe file
File compression utility
What does the disk cleanup do
Removes unnecessary files
Tool from windows
What is the application programming interface
the way for an application to interact with certain system/application
communication protocol between a client and a server intended to simplify the building of client-side software
Permits communication between server snd application
True or false
Does running more programs require more RAM
True
Does RAM have UNILIMITED capacity
Nah it has limited capacity
