Booting- is the process in which the computer tests all the components and the programs of the computer
to see whether it has problems or not before the computer fully starts.
GUI - or the Graphical User Interface, it allows users to interact using graphics rather than texts.
Linux - a free operating system
Macintosh OS - it is the most expensive among other Operating Systems. it is a good Operating System because first
it doesn't have viruses unlike others and it has unique programs that is only exclusive for the operating system,
but not many uses it because of the price only high earning people and big companies us it.
MS-DOS - or Microsoft Disk Operating System. it allows users to interact to the computer throught texts.
it is the most commonly used among the DOS family.
Multitasking - is the proccess of doing different tasks at the same time.
NOS - Network Operating System, Made by Linux/Unix. it is an operating system that focuses on networks.
OS - or the operating system, it is a system Software that is responsible for all other softwares in the computer.
System Software - a system software is responsible for all other softwares in the computer it is the one that
runs and commands other softwares, examples of these are Windows, Android, Mac OS, Linux, etc.
Application Software - software that does specific tasks individual to other softwares, examples of these are
Notepad, MS Word, Internet Explorer, etc.
UNIX - it is a multi-tasking mulit user based operating system.
Utility Programs - Programs that cleans and organizes the data in the computer.
Examples od Utility Programs are Disk Cleanup and Disk Defragmenter.
Windows - it is the most Famous, Most used and it is the most efficient among other Operating Systems,
created by the Microsoft Corporation.
Windows CE - is an operating system developed by Microsoft for embedded systems
it is a distinct operating system and kernel, rather than a trimmed-down version of desktop Windows.
Windows Mobile - Portable Windows Operating System in mobile Phones and other Mobile Devices.
Differentiate Mac OS VS Windows VS Linux
Mac OS - it is the most expensive among other Operating Systems. it is a good Operating System because first
it doesn't have viruses unlike others and it has unique programs that is only exclusive for the operating system,
but not many uses it because of the price only high earning people and big companies us it.
Windows - it the most commonly used Operating System, it is the first GUI integrated OS it is very easy to use
and it is not very expensive also. today the most stable Version of it is the Windows 7.
Linux - although it is a free OS very few uses it, for some reasons some people does not like it. some people only
use it for a substitute OS until they can buy efficient ones.

1.) Microprocessor was invented by Lee Boysel in 1969 as part of a multi-chip CPU.
2.) Computer power management settings whether you are using a Mac or PC, a laptop or a desktop, your computer has power-management features that can help you save money, reduce your impact on the environment, and extend the life of your hardware. shutting (or powering) down your computer if you weren't planning on using it for a period of two or more hours.
3.) The components and features that you must consider in buying a computer is.
a. Motherboard - it is the first thing that you must consider because it is the one that holds all the parts and components of the PC and you must consider if the processor that you will buy will be compatible with it.
b. Processor - it is the brain of the computer, it is the one responsible for processing all the data, and it is one of the factors you must consider if you want your computer to be fast.
c.Video Card (optional) - for heavy gamers, Video Card or Graphics card is one of the important components. it is the one responsible for the graphics of the computer.
4.)A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. SSDs are distinguished from traditional hard disk drives (HDDs), which are electromechanical devices containing spinning disks and movable read/write heads.
5.) Teleconference is the live exchange and mass articulation of information among several persons and machines remote from one another but linked by a telecommunications system. Terms such as audio conferencing, telephone conferencing and phone conferencing are also sometimes used to refer to teleconferencing.
6.) Solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. while Magnetic storage uses different patterns of magnetization in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads. and Optical storage is a term from engineering referring to the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning disc.
Solid-state drive will definitely replace other storage devices because it is non-volatile and very easy to use.

- Monitor/display sleep: Turn off after 15 minutes or less.
- Turn off hard drives/hard disk sleep: 15 minutes or less.
- System standby/sleep: After 30 minutes or less.

Stars...
A star is a massive, luminous ball of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth. Other stars are visible from Earth during the night when they are not outshone by the Sun or blocked by atmospheric phenomena.
Historically, stars have been important to civilizations throughout the world. They have been part of religious practices and used for celestial navigation and orientation. Many ancient astronomers believed that stars were permanently affixed to a heavenly sphere, and that they were immutable. By convention, astronomers grouped stars into constellations and used them to track the motions of the planets and the inferred position of the Sun.
