Data Measurement

From ICT lesson .. I have learn about data measurement in bo(2).

Do you know that 1 kilobyte is not 1000 bytes but 1024 bytes ...?? Very strange right??? Because in Mathematics, you know that 1 kilobyte is equal to 1000 bytes.. But in ICT, 1 kilobyte is equal to 1024 bytes.. At the first time I look at this note that I found in ICT note.., it is very strange.. so I look once again at the ICT note that teacher gave me and I found the reason why 1 KB is not 10000 bytes .. This is because..

Now I know why.
So 1 kilobyte is not 1000 bytes.. But 1024 bytes.. It is not like mathematics. Remember that..!!

Define Computer Ethics, Code of Ethics, Intellectual Property, Privacy, Computer Crime and Cyber Law.

Computer ethics is a system of moral standards or values used as a guideline for computer users.

A code of ethics often focuses on social issues. It may set out general principles about an organization's beliefs on matters such as mission, quality, privacy or the environment. It may delineate proper procedures to determine whether a violation of the code of ethics has occurred and, if so, what remedies should be imposed. The effectiveness of such codes of ethics depends on the extent to which management supports them with sanctions and rewards. Violations of a private organization's code of ethics usually can subject the violator to the organization's remedies (such as restraint of trade based on moral principles). The code of ethics links to and gives rise to a code of conduct for employees.

Intellectual Property refers to works created by inventors, authors and artists. These works are unique and have value in the market place. In our daily lives, we are surrounded by things that are protected by IP. Your school bags, your shoes and even your socks are protected by Intellectual Property rights. Nike, Bata or Adidas, for example, are all protected by a group of legal rights.

Privacy in IT refers to data and information privacy. Data refers to a collection of raw unprocessed facts, figures and symbols. Then, computer is used to process data into information. In general, data include texts, numbers, sounds, images and video. Information privacy is described as the rights of individuals and companies to deny or restrict the collection and use of information about them.

Computer crime or cybercrime is a form of crime where the Internet or computers are used as a medium to commit crime. Issues surrounding this type of crime have become high-profile, particularly those surrounding hacking, copyright infringement, child pornography, and child grooming. There are also problems of privacy when confidential information is lost or intercepted, lawfully or otherwise.
Computer crime encompass a broad range of potentially illegal activities. Generally, however, it may be divided into one of two types of categories:

(1) crimes that target computer networks or devices directly;

(2) crimes facilitated by computer networks or devices, the primary target of which is independent of the computer network or device.

Cyberlaw is a term that encapsulates the legal issues related to use of communicative, transactional, and distributive aspects of networked information devices and technologies. It is less a distinct field of law in the way that property or contract are, as it is a domain covering many areas of law and regulation. Some leading topics include intellectual property, privacy, freedom of expression, and jurisdiction.

The differences between computerised and non-computerised systems

COMPUTERISED AND NON-COMPUTERISED SYSTEMS

COMPUTER SYSTEM

A system is an arrangement of elements that when it is put together it becomes an organised and established procedure. A system typically consists of components connected together in order to facilitate the flow of information, matter or energy.

A computer system consists of a set of hardware and software which processes data in a meaningful way.

EDUCATION

It makes buying and selling activities easier,

more efficient and faster. For this application,

computers, Internet and shared software are needed.


In the e-commerce sector ,customers r, suppliers and employees benefits from the usage of ICT.

Define ICT

ICT (Information, communication and technologies) is the technlogy required for information processing, in particular, the use of electronic computers, communication devices and software applications to convert store, protect, transmit, and retrieve information from anywhere, anytime.

According to the European Commission, the importance of ICTs lies less in the technology itself than in its ability to create greater access to information and communication in underserved populations. Many countries around the world have established organizations for the promotion of ICTs, because it is feared that unless less technologically advanced areas have a chance to catch up, the increasing technological advances in developed nations will only serve to exacerbate the already-existing economic gap between technological "have" and "have not" areas. Internationally, the United Nations actively promotes ICTs for Development as a means of bridging the digital divide.

Paper ICT PK 1

I think paper ICT for PK 1 is quite difficult to answer.. but i still could answer it. Bwahahaha!!
Hmmhmm .. There was some questions that I couldn't answer properly. At first,I found the ICT paper was kinda easy for me.. But, when I reached at the middle I feel like I want to kill myself because that question supposed to be easy for me to answer but I didn't expected that questions would be very difficult for me to answer. However, I really hope that I can get A even A- for ICT paper because I think this paper is more easier than Add Math paper.. But, if I didn't get A for this ICT paper.., I hope teacher didn't get angry with me because my English is still very poor.. That's why I can't answer the question properly. I'm so sorry teacher.. T_T So, I hope anyone who read my blog will pray for my success.. Thank You everyone..
