Research the ff.

BOOTING:
->  Restarting a computer or its operating system software. It is of two types  Cold booting: when the computer is started after having been switched off.  Warm booting: when the operating system alone is restarted  after a system crash or 'freeze.' Both types of booting clear out  the bugs, bombs, memory conflicts, and other idiosyncrasies of the operating system.

GUI:
-> Graphical User Interface 
->   An interface for issuing commands to a computer utilizing a pointing device, such as a mouse, that manipulates and activates graphical images.

LINUX:
-> is a Unix-like operating system that was designed to provide personal computer users a free or very low-cost operating system comparable to traditional and usually more expensive Unix systems. Linux has a reputation as a very efficient and fast-performing system.

MACINTOSH OS:
-> Mac OS is the computer operating system for Apple Computer's Macintosh line of personal computers and workstations.

MS-DOS:
-> Microsoft Disk Operating System
-> it was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s to the mid 1990s, until it was gradually superseded by operating systems offering a graphical user interface (GUI), in particular by various generations of the Microsoft Windows operating system.

MULTITASKING:
-> Multitasking is the act of doing multiple things at once. It is often encouraged among office workers and students, because it is believed that multitasking is more efficient than focusing on a single task at once. Numerous studies on multitasking have been carried out, with mixed results. It would appear that in some cases, multitasking is indeed an effective way to utilize time, while in other instances, the quality of the work suffers as a result of split attention. 

NOS:
-> network operating system
-> The system software of a local area network (LAN) that integrates the network's hardware components, usually adequate for connecting up to 50 workstations. Included, typically, are such features as a menu-driven administration interface, tape backup of file-server software, security restrictions, facilities for sharing printers, central storage of application programs and databases, remote log-in via modem, and support for discuss workstations. 

OS:
->operating system
->  is software, consisting of programs and data, that runs on computers, manages computer hardware resources, and provides common services for execution of various application software  

SYSTEM SOFTWARE:
-> is computer software designed to operate the computer hardware and to provide a platform for running application software. 

APPLICATION SOFTWARE:
-> software that does specific tasks individual to other software, 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.

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 
-> t 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.

opinion of solid-state storage to magnetic and optical storage media.

  • Computer data storage is often called storage or memory, refers to computer components and recording media that retain digital data.
  • Data storage  is one of the core functions and fundamental components of computers.
  • Magnetic media is Any storage medium that utilizes magnetic patterns to represent information. A good example of a magnetic media is a floppy diskette.

Teleconferencing Technology..

     Teleconferencing technology has provided businesses with an entirely new way of communicating over long distances. In fact, it helps business save money on travel expenses and has also helped business owners increase the productivity of their business by providing them with the ability to communicate via telecommunication methods. Finally, as more businesses catch onto the teleconferencing technology wave, people will see more and more businesses reaping the.

what is solid state storage?

Solid-state storage-is a nonvolatile, removable storage medium that employs integrated circuits the main advantage of solid state storage is the fact that it contains no mechanical parts.
The Solid State Storage Initiative  has created a Solid State Storage Technical Work Group to create a reference  architecture and facilitate industry-wide adoption of common requirements, methods, and specifications in related standards organizations.

list of components in features..

This are the list of components in the features:
  • Products property- is a read-only property that returns a string list object enumerating the set of all products installed or advertised for the current user and machine.
  •  features property-is a read-only property that returns a string list object enumerating the set of published features for the specified product.
  • feature Parent property -specifies the parent feature of a feature. An empty string for this property indicates the feature has no parent and is a root item.
  •  feature state property-returns the installed state of a feature.
  • Components property-returns a String List  object enumerating the set of installed components for all products.
  •  Component clients property-object enumerating the set of clients of a specified component.
  • Component path property-is a read-only property that returns the full path to an installed component. If the key path for the component is a registry key then the registry key is returned.  
  • Last error record Method-the installer object returns an record object that contains error parameters for the most recent error from the function that produced the error record. 
  • Registry value method-the installer object reads information about a specified registry key of value. If the key or value specified does not exist, the method returns an error of 9, "Subscript out of Range." 

report of computer power management...

  • Abstract-the personal computers  and monitors has the potential to save significant amounts of electricity as well as deliver other economic and environmental benefits.
  • The  Energy Star program has transformed the PC market so that equipment capable of power management is now widely available. However, previous studies have found that many are not accomplishing energy savings. The principal  reasons for this are systems not being enabled for power management or a circumstance that prevents power management from operating. This guide is intended to provide information to computer support workers to increase the portion of systems that successfully power manage. 

who invented the microprocessor?

* the first invented the microprocessor "Ted Hoff of Intel the"during  4004 in a project that began in 1969. It was perfected and officially announced to the public in 1971.  After that Ted went on to help design the 8008 and the 8080 microprocessors before leaving Intel to join Atari in the 1980s.
