   Introduction To Computers Table of Contents: Introduction to Computers Applications and Areas of Computers Basic Task of a Computer Information and data Information Processing Cycle Introduction to Computers: => What is Computer Computer can be defined as an electronic device which is capable of: Receiving Input Processing the data on the basis of given sets of instructions. Producing the Output. Storing the information (If Needed) Is this a Computer? Can we give it an input? Can it process the input? Can we get an output from it? Storage (if necessary). So as we know we can give it an input, it will process the input and will provide us an output and storage can be done as well. So therefore it is a Computer. Can we give it an input?

 READING COMPREHENSION-II TEST 02 PASSAGE 01:               A team of researchers has found that immunizing patients with bee venom rather than the crushed bodies of bees can better prevent serious and sometime fatal sting reaction in more than one million Americans who are hypersensitive to bee stings. The crushed body treatment has been standard for fifty year, but a report released recently is said that it was ineffective. The serum made from crashed bodies of bees produced more adverse reaction than the injection of venom did.     The research compared the results of crushed body treatment with the results of immunotherapy, that uses insect venom and also compared with the results of placebo. After six or ten months of immunization, allergic reactions to stings occur in seven of twelve patients treated with the placebo, seven of ten with crushed body  extract and one of the eighteen treated with the venom. 1. What is the main topic of the passage     a. A new treatment for people

 READING COMPREHENSION ECAT AND MDCAT ENGLISH TEST 01 PASSAGE 01:                         When used for studies of learning and memory, the octopus is more interesting subject than the squid. Unlike the free swimming squid which relies exclusively on its eyes to guide it to tasty fish or crab, the octopus often feeds of the bottom of the sea. It not only uses its eyes but also tentacles to identify a likely meal. The brain of the octopus has two separate memory-storage areas one for visual memory and another for tactile memories. 1. How does squid find its food.     a. By sight only     b. By touch only     c. Both by sight and by touch     d. None of these 2. According to the passage, which of the following can describe the octopus     a. Its brain is simpler than that of squid      b. It can not took and touch at the same time     c. Its brain does not function very well     d. The memory of what it has seen and touched is contained in                     separate areas. 3. The passa
