Intro To Operating Systems

1 . Operating System : It takes the hardware and stores the rescources in to the system. There's one thing called the processor memory it stores disk space It stables the applications
for the hardware to knoe what details might show on there.

2. Computer Operating Systems : Most people use laptops , and PC it includes Microsoft
Windows. But Macintosh computers upload Mac OS X. Many
people use Linux or UNIX to operate there systems.

3. How Operating Systems Work : Other devices they use for internal operating systems are cell
phones to wireless access point. The devices they used
got so powerful that they actually run all the operating
system and applications.

4. Do All Computers Have Operating Systems : Not all computers operate the systems it has
sets of tasks that they perform. It inputs the
numbered keypad and presets a few buttons.
The hardware never changes when it operates
and controls the system.

5. Most Common Operating Systems : Microsoft Windows , MacIntosh has got MAC OSX


6. Operating Systems For Coded Physical Circuits : The operating systems can be changed or be
modified without throwing the device away.

7. Two Main Functions Of An Operating System : 1. It manages the hardware and software
resources of the system.

2. It provides stable and consistent way for
applications to deal with hardware.

8. Four Types of Operating Systems : 1. Real-Time Operating Systems ( RTOS )
2. Single-User , Single Task
3. Single-User , Multi-Tasking
4. Multi-User

9. First Action Of A Computer When it's Turned On : When the computer is turned on the first
thing comes up on are instruction that are
kept in it's memory. The hardware
examines the system to make sure if it
functions properly

10. What Is A Bootstrap Loader : A bootstrap is a program that loads a small program and that
functions in the operating system to it's memory and can be
allowed to begin the operation.


11. How Does The OS Manage The Processor: The software preforms actions and is controlled
by a user , others's by applications and by the
operating systems. It can process the application
by operating the system controls and schedules.
On a single-tasking system the schedule is
straightforward.

12. Two Operating System That Processes In Multi-Tasking : The operating system processes
two multi-tasking allows a certain
amount for the CPU to execution
one program.

13. What Is Thrashing : It happens without direct inteference and the CPU cycles to accomplish
it's task in a limited amount of time. The user can can be in trouble if
they load to many functions at once. The CPU cycles and saves the
registers, queues of the application process.

14. What Is Virtural Memory Management : Computers add memory to it's original disk to
expand the RAM to 1 to 2 gigabytes. Most
information and applications are stored in it's
memory.
15. What Is A Driver : A driver is an operating system that signals the electricity from the
hardware.

16. How to Input/ Output Capabilities Of A System To Be Enhanced : Install a driver.



17. How Do Applications Program Interfaces Make It Easier For Programmers : The drivers
allow the
applications to
use the
subsystems
without knowing
the detail on the
hardware's
operation.
18 What is UI And GUI : UI stands for user interface and GUI stands for Graphical User
Interface
19 Why Is Linux Being Open Source Significant : Linux is free , you can customize for your own
use and anyone can make changes.
20. Other Devices That Run On Linux : Mac OS X and Microsoft Windows
21 Three Thing I Learned About operating Systems Are : 1 It stores the resoucres in the system
2. Some devics can be used for cell
phones and wireless access point.
3. The operating system is modified
even though the device is thrown
away.
22. How To Prevent A Computer From Overheating : There's a built in fan that prevents from
overheating

Peer to Peer Networking

Peer to Peer : is a network operating system that connects to other computers on the network
the advantage is cheaper then buying new server to share resources and the
disandvantage is the program has to keep running for access

Cient/Server: is centralized provides to access to sources all the time
has security and the disadvantage is more expensive and must be on all the time

Networking

Unshielded Twisted Pair : A unshielded twisted pair is a cable that comes in to varieties shield
and unshielded.

Coaxial Cable : a coaxial cable is a single copper that blocks any interference from lights , motors
and diffrent computers.

Fiber Optic Cable : A fiber optic cable is a glass surrounded by serval layers of matrieals. The
singal transmit the elimation to decrease the electrical problems.

Case Fan : The case fan cools off the hard drive

Motherboard Battery : Help's keeps the time and settings while the computer is turned off.

Power Supply : The power supply powers the computer. It uses electricity.

Power Cable Connecters : The cable connectors connect from the hard drive to the power supply.

Front Panel Connector Cables : They connect the front panel to the motherboard. They keep the activity light and power light on.
