Current Affairs

Current Affairs Study the following examples. · Example 1 Read the passage carefully and answer the questions that follow: Part of the computer system of the Large Hadron Collider (LHC) was hacked into as the world?s most powerful physics experiment got under way. A group calling itself the ?Greek Security Team? hacked into a computer connected to the system last Wednesday A spokesman for Cern, the lab that houses the LHC, said the hackers put up a message on the facility's website. No harm was done but the incident has highlighted the need for security in the LHC's network, the spokesman said. The hackers had targeted the computer network of the Compact Muon Solenoid Experiment (CMS), a huge detector that analyses data from the particle accelerator. The LHC is attempting to recreate the conditions just after the Big Bang, in which the universe was created. With the world watching as the first particles began circulating in the LHC, engineers were searching the hacked computer for possible malicious damage. The CMS website displayed a page with a mocking message, in Greek, which included the line: ?We are 2600-don't mess with us?. It was not a malicious hack and it was quickly detected... but this sort of thing keeps you on your toes. As a result of the attack, the CMS webpage, www.cmsmon.cern.ch, can no longer be viewed. Cern spokesman, James Gillies, told the BBC that the compromised computer was not connected to the accelerator itself. ?The computer is used to monitor one of the experiments at the LHC, it has nothing to do with the LHC accelerator itself or any of the control systems,? he said. ?It seems it was not a malicious hack and it was quickly detected and corrected but this sort of thing keeps you on your toes.? Mr. Gillies said that the LHC had a general access network and a more restricted access network which controls the sensitive systems. Weakness introduced, he said that the experiment involved 10,000 scientists at 500 universities in 80 countries and that keeping on top of the systems? security was ?not trivial task?. ?As far as I understand there was one user somewhere-who wasn?t a hacker-who uploaded something on to this machine and inadvertently introduced a weakness that allowed people to get in,? he said. ?Our IT department is constantly reminding the experimental collaborators of security issues regarding the network and will continue to do so,? he said. ?This may have strengthened their message.? The number 2600 is often used by the hacking community. It is believed to have originated in the US in the 1960s with the discovery that a tone of 2600Hz played down the line could be used to access restricted parts of the national telephone system. 1.

Grammar (All Topics)

Grammar (All Topics) 1. THE SENTENCE When we speak or write we used words. We generally use these words in group as for example- Little Jack Horner sat in a corner. A group of words, which makes complete sense, is called a sentence. KINDS OF SENTENCES Kinds of Sentences There are mamly five kinds of sentences. 1. Assertive sentence: A sentence that states or declares something is called an assertive or declarative sentences. 2. Interrogative sentence: A sentence that asks a question is called a question or an interrogative sentence. For example: What time did you come? 3. Imperative sentence: A sentence that expresses a commond, request, suggestion, order or advice is called an imperative sentence. For example: Keep silence. 4. Exclamatory sentence: A sentence that expresses some strong feelings or emotions such as joy, sorrow, surprise or contempt is called an exclamatory sentence. For example: How beautiful the flower is! 5. Optative sentence: A sentence which expresses wish, desire or pray is called an optative sentence. For example: May God bless you! 2. TENSES Study the following sentences: 1. My father goes for a morning walk daily 2. She is reading a magazine. 3. I saw Kate yesterday. 4. She was knitting a scarf. 5. We shall go to the zoo tomorrow. 6. He will arrive here next Monday All these sentences refer to certain actions at certain points of time. Sentences 1 and 2 refer to actions happening now, i.e., the present. Similarly, sentences 3 and 1 express actions that happened some time ago, i.e., in the past. Sentences 5 and 6 express actions that will take place some time from now, i.e., in the future. We may refer to tenses as time references.

Study the following diagram: We see that past extends from the speaker's present to the beginning of time, while future extends from the speaker's present to the end of time. We also infer that present divides time but itself moves towards future. 3. MODALS Study the following diagram:

Judging Completeness of Process

Judging Completeness of Process While writing the factual description of an object, instrument, animal, place or person we should give the reader an impression that he himself knows about it.
