Other wise most shops will do it for you. or maybe not in the Philippines.

How To Find Out What Firmware Version You Have.
You can find your phones firmware version by entering *#0000# on the phone while it is in standby.

Restore Factory Settings
Enter *#7780# on the phone while it is in standby. This will reset it to the factory settings and wipe most of the stuff from the phone (contacts, connection settings etc).

Display Handset’s Warranty

*#92702689#
Here you can view the S/N and the IMEI as well as the life timer (newer models). The date the phone left the factory and the date it was purchased. If your phone has been repaired the date of the repair is also visible. You will need to turn the phone off to exit this menu. Newer phones simply require you to press ok.

Operating System

Data   Base

 

 

 

A database is a collection of related information stored so that it is available to many users for different purpose. The content of a database is obtained by combining data from the entire different source in an organization. So that data are available to all users and redundant data can be eliminated or at least minimized. A Computer database gives us some electronic filing can be eliminated large number of ways of cross referring and this allows the user many different ways in which to reorganize and retrieve data.

 

The Three Level Architecture of Database management system

 

• External level or subschema
• Conceptual level or conceptual schema
• Internal level or physical schema
• Mapping between different levels.

 

Database management system facilities

 

Data definition language;

Database management system provide a facility known as the data definition language (DDL), which can be used to define the conceptual schema and also give some details about how important this schema in the physical devices used to store data.

 

Data Manipulation Language;

DML is a language that enables users to access or manipulate as organized by the appropriate data model. Data manipulation involves retrieval of data from the database, insertion of new data into the database and deletion or modification of exiting data.

 

Elements Of a database management system;

 

1. DML Precompiler
2. DDL compiler
3. File manager
4. Database manager
5. query processor
6. Database Administrator

MULTIMEDIA

MULTIMEDIA

 

The previous of windows and DOS were not designed to support multimedia, therefore the multimedia presentations were either not running very slowly. With Windows 95, things are improved as it supports multimedia at the base level, as discussed below;

 

• Multimedia presentation require more than one media, and Windows 95 is a 32 bit, Multitasking and multithreading operating system. This assure plating more than one media smoothly and more responsive to user interaction.
• During installation procedure of Windows 95, it automatically detects and configures itself for multimedia devces.
• Windows 95 allows you to create compounded documents that include sound, video, graphics, charts, pictures, and other elements from various applications.
• A new CD-Rom file system in Windows 95 improves CD-Rom performance. 

 

Multimedia types;

 

The different media types are either audio or visual. Multimedia information is stored in sound, video, or MIDI file format.

 

Audio;

 

Recording and playing back sound were the first multimedia application fro personal computers. With the help of installed sound card, you could record a voice, store it in file on disk and play back the same sound on another computer. Music and sound can be recorded for computer generated presentation.

 

WAVE audio- Actual sound waves are recorded and converted to digital data;

 

MIDI Audio- It is the recording of keystrokes or other actions that direct synthesis and the MIDI compactable electronic Music devices to generate sound. Thus these files are similar in size.

  

Videos:

 

This media includes the following files;

 

Animation-The first thing that comes in mind are the animation movies like jungle book. Animation is the images that move on the screen. The animation movies include these kinds of images and sound.

 

Video-The videos pictures can be recorded from cameras or laser discs into a computer and store it on the disk. To capture High quality video and store it efficiently these files needed to be compressed.

COMPUTER VIRUS

COMPUTER VIRUS

 

The evolution of virus;

 

The concept of virus dates back to 1949, when John von meumann submitted a paper putting forward the concept of a “Self Replicating” program; the idea seemed impossible and was dropped. Subsequently, the first virus like program appeared in the form of a recreational game called “CODE-WARS” at the bell labs of American telephone and Telegraphy Company. In “CODE-WARS” two players were to code a set of program that would destroy the other players programs. Concurrently at Massachusetts institute of technology, students were carrying out experiments with computer, which no body had ever tried.

 

Classification of Virus;

 

Viruses are classified on the basis of their mode of existence and there are three categories of viruses;

 

1. BOOT infectors.

 

1. SYSTEM infectors.

 

1. GENERAL EXECUTABLE PROGRAME infectors.

 

BOOT infectors;

 

As the name suggest, they are characterized by the fact that they physically reside in the boot sector [0(Zero)] sector of the disk. A system infected by such a virus will have the virus residing in a particular area of the disk rather than in a program file. These viruses get loaded soon after the power on self test and control the system and remains in control at all times. They sometimes have the capability to trap soft booting (i.e. CTRL ALT DEL) and remain in control even if the system is booted from a non-infected floppy, thereby contemning the clean floppy.

 

SYSTEM infectors;

 

This second category of viruses deals with the components of the system itself. All machines without exception require an operating system in order to create an environment in which the operator works. In MS-Dos, Command.com contains all not loaded onto the memory when the machine is booted. The system infectors attach themselves to a file such as COMMAND.Com or other memory resident files and manipulate these files.

 

 

 

 

GENERAL .COM or .EXE Infectors;

 

From the infection point of view, these viruses are most dangerous and devastating of the three classes of viruses. They attach themselves to program files and can spread to almost any executable program in any system. These viruses change the original program instructions into a Jump to its own code and follow that code with a return to the original program. As a result, whenever the program is executed, the viruses get loaded and executed first and then allow the original program to proceed. It remains memory resident and infects each and every program that is loaded for execution.

  

 

 

CRYPTOGRAPHY

 

Cryptography: A brief history

 

 

 

 

In the current scenario of computer usage that predict is that network are likely to be present everywhere, security has become much talked about issue. Especially with the relatively easy access to the internet the confidence in the sanctity of the data is a major concern.

 

However the science of cryptology is at least 4,000 years old. Cryptology is defined as the design and analysis of codes and cipher’s. In the first 3,000 years, cryptology was developed independently in several ancient cultures including Egypt India and Mesopotamia. Perhaps the oldest evidence of cryptology is an ancient inscription, carved about 1900 BC in the main chamber of an Egyptian tomb. It used some unusual hieroglyphic symbols in place of more ordinary symbols.

 

Plain:               ABCDEFGHIJKLMNOPQRSTUVWXYZ

 

Cipher:            DEFGHIJKLMNOPQRSTUVWXYZABC

 

Using this system the secret message “ZHOFRPH WR WKH FRPSXWHU FRXUVH” would actually mean “welcome to the computer course”. There were of course other systems developed around the similar time in the history which includes approach such as:

 

·        Writing secret message backwards.

·        Writing message vertically rather than horizontally.

·        Substituting dots for vowels.

·        Substituting special symbol for normal of alphabets.

 

A Caesar type encryption mechanism can be easily is detected by trying all possible displacements till the message becomes meaningful.

Cryptography is the process of transforming plain text or original information into an unintelligible form so that it may be sent over unsafe channels of communication.

Human Education:

Here is the theory of human values free from the atmosphere of any single religion. It is perfectly secular theory in as much as it does not involve belief in any particular religion in order to parties it. This theory of education should find wide acceptance. It can be the basis of academic as well as moral and spiritual education. The theory gives a certain world view. This worldview is not theological, nor is it scientific. It is partly humanistic and partly mystical in that it accepts the existence of an entity which figures in ancient Indian Psychology-the soul.

The theory of education as it generally practiced today is summed up in five simple words. The first one is Knowledge. It is knowledge for its own sake that our universities aim at giving to students. Knowledge is truth, which is intellectually apprehended. Skill, the second word,

Is one of the main concepts in education? Skill has many facets of its own. It may extend from skill in attending to personal behavior. It is really an ethical skill in one own personal. This is one of the choicest gifts that education has to give. It helps us to steer clear of all controversies and arrive at a synthesis or conciliation of opposites. It is a good sign of culture of a person that he has this balance and that he bring together are reconcile different points of view. Unhealthy and harmful feelings are eliminated, refined are sublimated. The education or cultured man always maintains his balance even in the midst of stress and strain.

1. Self-help skills: the child has to learn how to brush his teeth and dress cleanly. The nature of body-care, for example, goes on changing with each stage of life.

1. Social skills: beginning as skills concerned with a certain kind of behavior in the classroom and on the road, committee-work in school and college, some administration work as in the running of gymkhana department.

1. classroom and subject skills : another kind of skills has also to be continuously developed, civilization of memory and cultivating the skill reverent to the mastery of a subject.

Feeding

Feeding:

 

At the season when the British paterfamilias is sending his children on their Christmas visit to the dentist it must occur to him to wonder why the noble savage never has any trouble with his teeth. It is said that they kept healthy by the hard work they have to do in tearing tough meat without the help of Knife and fork. These implements and, the art of cookery, are reducing man to a toothless animal, and are perhaps, responsible for such evils as appendicitis and cancer, from which savages hardily suffer at all.

           

            This is only a sample of what civilization is doing to us, and civilization, for the majority in every nation, is not yet a hundred years old. until quite lately the housewife used to bake her own bread, make her own jam, and offer her friends home-brewed wine. Now she can do none of these things. The laborer, before the industrial revolution, was a handy man, almost self-sufficing. now he understands only one thing-perhaps how to punch out biscuits from a slab of pulp without making the circles interests.

 

            Mr. Austin freemen, whose observation of savage people have made him keenly alive to the evils of machinery. Describe how his caravan was overtaken by a storm in central Africa. The natives set to work in the forest, and in a few hours a row of serviceable waterproof huts had been constructed. The despised savage would no more ask the government to spend a thousand pounds in building a house for him than he would ask it comb hair.

 

There is general slackness and dislike of unnecessary exertion among our younger people. It affects their religion, which they like to have given them. This is certainly not the way of the cross and it compares badly with Michelangelo’s words: 

SEX

Woman Sex:

 

TO CALL Woman the weaker sex is a libel; it is man’s injustice to woman. If by strength, then, indeed, is woman less brut than man. if by strength is meant moral power, the woman is immeasurable man’s superior. Has she not greater institution, she is not more self-sacrificing, has she not greater powers of endurance, and has she not-violence is the law of our beings; the future is with woman…. Who can make a more effective apple the heart than woman?

 

HAD NOT man in his blind selfishness crushed woman’s soul as he done or had she not succumbed to the enjoyments’ she would have given the world an exhibition of the infinite strength then is latent in her. The world shall see it in all its wonder and glory when woman has secured an equal opportunity for herself with man and fully developed her powers of mutual aid and combination.

 

WOMAN ARE special custodians of all that is pure and religious in life. Conservation   by nature, if they are slow to give up all that is pure and noble in life.

I AM uncompromising in the mature of women’s rights. In my onion she should labor under no legal disability not suffered by men. I should treat daughters and sons on a footing of perfect equality.

 

I BELIVE in the proper education of woman. But I do believe that woman will not make her contribution to the world by mimicking or running a race with men. She can run the race, but she will rise to the great heights she is capable of by mimicking man. She has to be the complement of man.
