1- Computer-based translators often perform translations rather badly because they are programmed to translate words, not paragraphs. The translator does not know the proper grammar and sentence structure, and cannot translate a full paragraph properly. It translates word for word instead. If the person using this translator were to translate the words they did not know, and put them in the proper sentence structure, the translation would probably turn out better.
Language use can be variable so translation is not precise. word by word translation, no context, synonyms, colloquial use of language. Different word order,
2- Markup language is the language of the internet. It writes the webpage to be published.
is a text-based languge in web pages. tags are inserted in text of page to tell a web browser how to display the text on a user's screen. the coding is then interpreted by a computer program. the info is presented so it is accessible across a wide variety of hardware and other applications

Electronic commerce and business Questions
a) Is e-commerce possible without the Internet? Explain.
No. E-commerce is, by definition, the conduction of business through telecommunication systems. These days, it is almost completely done by Internet. Without the internet, it would be very hard to conduct business. There would be no website to visit, no emails to send.
b) Describe the 3 forms of e-commerce
Business to business: B2B- where a company handles transactions with other businesses and organizations such as its suppliers.
Business to consumer: B2C- retail transactions between an company and individual customers. Examples are amazon.com and other websites that sell to customers through a website
Consumer to Consumer: C2C- individuals, organizations and companies that buy and sell directly with each other over the internet. Example: Ebay
c) What are the purposes of an intranet? What are the main characteristics of an intranet?
The intranet serves to improve communications within an organization, and provide easy access to information. Characteristics include at least one computer with server software installed, and other computers with client software installed, both with TCP/IP. A LAN or WAN is also needed. Middleware handles the communication connections between computers, printers and other devices on the networks. TCP/IP handles communication between client and server computers. Firewalls are used to secure the system.

IB Test Practice
1- Two input devices that would be used in a pilot training computer simulation are a joystick or a wheel to control the machine and a keyboard or mouse to navigate around the screen and select the simulation to be used.
2- An advantage of schools providing students with USB drives is that students who might otherwise not be able to purchase them will be able to have access to one, and all the students will have equal access to this device. A disadvantage is that students may lose the drives, requiring replacement, or misuse them, saving non-school related material on them.

Practice test questions
1- Computer simulation is the use of computers to imitate an environment that students can explore and learn in, without facing the dangers that they would face in real-life.
Answer: Computer simulations are those programs based on models (descriptions of reality) in order to imitate a certain scenario. Simulations can be used in a wide sprectrum of areas, including business (stock markets), traffic, training (especially for military purposes), communalistic matters, and the weather.
2-Bandwidth is the frequency at which information travels over a network or the Internet.
Answer: Bandwidth refers to the speed and capability of a connection (internet) to transfer a certain amount of data per unit of time. Most of the time, the unit of time are seconds and data is classified into kb. It also refers to the physical measurements of the band through which connection cables pass.
