II. Choose from sentences A-G the one which fits each gap 1-5. There is one extra sentence you do not need to use. (1,0 p)

Every body has heard about the Internet, but do you know what an “internet” is? (0)___B____

In fact, intranets make use of the same software programs as the internet to connect computers and people. (1)_____F_____.

If your intranet is working properly, it can link together huge amounts of information which is stored in different places in the company. _____C_______.

A company intranet can, of course, be used for unimportant information like office memos and canteen menus. (3)______E_____.

The intranet is a great idea, but the systemonly works if everyone on the intranet is willing to share their information with other people. (4))______A_____.

Another problem which often occurs is that top managers like to use the intranet to “communicate down” rather than to “communicate across”. (5)_____G_____.

Unfortunately, many departments don’t want to share specialist knowlegde with others.
It is a computer network that is private to a company, university, etc, but it is connected to and uses the same software as the Internet.
In this way, people can get the information they need, regardless of where it comes from.
Most employers prefer to communicate by telephone or in writing.
But an intranet should provide important information which people need to make decisions about new products, costing and so on.
This means that you do not have to buy a lot of additional programs to set up an intranet service.
That is, they use the intranet to give orders, not to exchange information between themselves and others working in the same organization.

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

As computer use becomes more common, the need for security is more important than ever. One of the greatest security threats in the online world is computer hacking. Computer hacking is the unauthorized access to a computer or network of computers. Hackers are people who illegally enter systems. They may alter or delete information, steal private information, or spread viruses that can damage or destroy files. But how exactly can a hacker get into a system to do these things?

Most hackers use information called protocols that are built into computer software. These protocols allow computers to interact with one another. Protocols are sort of like computer police officers. When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems. Hackers can manipulate the protocols to get unlimited access to a computer system.

In fact, just the act of entering a computer network is considered hacking. This is commonly called passive hacking. Passive hackers get a rush from just being able to access a challenging system like a bank or military network. Another kind of hacker tries to do damage to a system. After hacking into systems, these hackers release viruses or alter, delete, or take information. Known as active hackers, they are, by far, the more dangerous of the two.

The easiest way to protect a system is with a good password, Long and unusual passwords are harder for hackers to guess. For even greater security, some online services now use “password-plus” systems. In this case, users first put in a password and then put in a second code that changes after the user accesses the site. Users either have special cards or devices that show them the new code to use the next time. Even if a hacker steals the password, they won't have the code. Or if the hacker somehow gets the code, they still don't know the password.

It is implied in the passage that ______.

A. it is difficult to protect data from being stolen by hackers.

B. not every hacker is harmful.

C. hackers always damage the information in the host computer.

D. online services have been improving their security system.

A. thật khó để bảo vệ dữ liệu khỏi việc bị tin tặc đánh cắp.

B. không phải mọi tin tặc đều có hại.

C. tin tặc luôn gây hại cho các thông tin trong máy chủ.

D. các dịch vụ trực tuyến đã cải thiện được hệ thông bảo mật của họ.

Căn cứ thông tin đoạn cuối:

“For even greater security, some online services now use “password-plus” systems. In this case, users ﬁrst put in a password and then put in a second code that changes after the user accesses the site. Users either have special cards or devices that show them the new code to use the next time.”

(Để bảo mật hơn nữa, một số dịch vụ trực tuyến hiện nay đã sử dụng hệ thống “mật khẩu cộng mật khẩu”. Trong trường hợp này, trước hết người dùng nhập mật khẩu, sau đó nhập tiếp một mã thứ hai mà luôn thay đổi sau khi người dùng truy cập vào trang mạng. Người dùng sẽ có các địch vụ hoặc thẻ đặc biệt cho họ biết mã truy cập mới cho lần đăng nhập tiếp theo.)

C. Lượng thông tin được chia sẻ giữa 2 hệ thống máy tính phụ thuộc vào máy chủ.

D. Dữ liệu mà các tin tặc có thể lấy được từ các máy tính khác có thể là vô hạn.

“Most hackers use information called protocols that are built into computer software. These protocols allow computers to interact with one another. Protocols are sort of like computer police ofﬁcers. When a computer connects to another system, the protocols check to see if the access is valid. The protocols can also determine how much information can be shared between the two systems.

(Hầu hết tin tặc sử dụng một loại thông tin được gọi là các giao thức được cài vào trong phần mềm máy tính. Những giao thức này cho phép các máy tính kết nối với một máy tính khác. Các giao thức hoạt động như những cảnh sát máy tính. Khi một máy tính kết nối được với một máy tính khác, các giao thức sẽ kiểm tra xem liệu quyền truy cập có hợp pháp không. Các giao thức này cũng có thể quy định mức thông tin có thể chia sẻ giữa 2 hệ thống máy tính là bao nhiêu. Các tin tặc có thể thao túng các giao thức này để có quyền truy cập vô hạn vào hệ thống máy tính kia.)
