Chapter 3 : Lesson 3
The title for lesson 3 in chapter 3 is PC care and safety procedures for users, well as the title says, it teaches us, students, how to take care of computers. We will also learn the different factors that can affect the efficiency of the computer and the health risks it can give to the users.
We can consider computers are sensitive equipments that can be damaged by different factors. They can also cause health hazards to users if not treated properly.

different types ofcomputer (late na nagpost )
A computer is one of the most brilliant inventions of mankind. Thanks to the computer technology, we were able to achieve an efficient storage and processing of data; we could rest our brains by employing computer memory capacities for storage of the information. Owing to computers, we have been able speed up daily work, carry out critical transactions and achieve accuracy and precision in work output. The computers of the earlier years were of the size of a large room and were required to consume huge amounts of electric power. However, with the advancing technology, computers have shrunk to the size of a small watch. Depending on the processing powers and sizes of computers, they have been classified under various types. Let us look at the classification of computers.
Different types of Computers
Based on the operational principle of computers, they are categorized as analog computers and hybrid computers.
Analog Computers: These are almost extinct today. These are different from a digital computer because an analog computer can perform several mathematical operations simultaneously. It uses continuous variables for mathematical operations and utilizes mechanical or electrical energy.
Hybrid Computers: These computers are a combination of both digital and analog computers. In this type of computers, the digital segments perform process control by conversion of analog signals to digital ones.
Following are some of the other important types of computers.
Mainframe Computers: Large organizations use mainframes for highly critical applications such as bulk data processing and ERP. Most of the mainframe computers have the capacities to host multiple operating systems and operate as a number of virtual machines and can thus substitute for several small servers.
Microcomputers: A computer with a microprocessor and its central processing unit is known as a microcomputer. They do not occupy space as much as mainframes. When supplemented with a keyboard and a mouse, microcomputers can be called as personal computers. A monitor, a keyboard and other similar input output devices, computer memory in the form of RAM and a power supply unit come packaged in a microcomputer. These computers can fit on desks or tables and serve as the best choices for single-user tasks.
Personal computers come in a variety of forms such as desktops, laptops and personal digital assistants. Let us look at each of these types of computers.
Desktops: A desktop is intended to be used on a single location. The spare parts of a desktop computer are readily available at relative lower costs. Power consumption is not as critical as that in laptops. Desktops are widely popular for daily use in workplaces and households.
Laptops: Similar in operation to desktops, laptop computers are miniaturized and optimized for mobile use. Laptops run on a single battery or an external adapter that charges the computer batteries. They are enabled with an inbuilt keyboard, touch pad acting as a mouse and a liquid crystal display. Its portability and capacity to operate on battery power have served as a boon for mobile users.
Personal Digital Assistants (PDAs): It is a handheld computer and popularly known as a palmtop. It has a touch screen and a memory card for storage of data. PDAs can also be effectively used as portable audio players, web browsers and smart phones. Most of them can access the Internet by means of Bluetooth or Wi-Fi communication.
Minicomputers: In terms of size and processing capacity, minicomputers lie in between mainframes and microcomputers. Minicomputers are also called mid-range systems or workstations. The term began to be popularly used in the 1960s to refer to relatively smaller third generation computers. They took up the space that would be needed for a refrigerator or two and used transistor and core memory technologies. The 12-bit PDP-8 minicomputer of the Digital Equipment Corporation was the first successful minicomputer.
Supercomputers: The highly calculation-intensive tasks can be effectively performed by means of supercomputers. Quantum physics, mechanics, weather forecasting, molecular theory are best studied by means of supercomputers. Their ability of parallel processing and their well-designed memory hierarchy give the supercomputers, large transaction processing powers.
Wearable Computers: A record-setting step in the evolution of computers was the creation of wearable computers. These computers can be worn on the body and are often used in the study of behavior modeling and human health. Military and health professionals have incorporated wearable computers into their daily routine, as a part of such studies. When the users’ hands and sensory organs are engaged in other activities, wearable computers are of great help in tracking human actions. Wearable computers are consistently in operation as they do not have to be turned on and off and are constantly interacting with the user.
These were some of the different types of computers available today. Looking at the rate of the advancement in technology, we can definitely look forward to many more types of computers in the near future.

THE 3 IDIOTS PART THREE :))
Rancho is calling someone because there is an emergency.He saw a girl with a motorcycle,he borrow the motorcycle with the girl. They go to a house and brought a sick person into the hospital with the motorcycle. In the hospital his one friend saw his father and because of that he thanked Rancho.the girl fell in love with Rancho and she think that all the characters in the television is Rancho and she think that she is dancing with him. on that morning she go to the hospital and she saw that the three were sleeping so she wake up them because they have an exam. when they go to their exam they were 30 min. late but they take the test. their teacher did not accept their test so when their teacher is arranging the test papers they rumble the test papers and put their test papers to others. After that they went to see the results Rancho's two friends was in the 2 last positions. they taught that Rancho did not pass the test. but the girl saw that Rancho is the top notcher. After that they drink too much alcohols. After many days, the two go to Rancho's house. They saw Rancho's father that is dead. They try to speak with him but they saw different face. They asked him where is their friend but he get his rifle, so they get his father's urn and they said to him that they will flush the ashes in the toilet. So he tell the truth that he is a true Rancho and the one their friend is their gardener. When the fake Rancho is in the 6th grade the true Rancho always gives his assignment to him for him to answer. When the math teacher saw the fake Rancho solving a 10th grade math, he was to say it to the principle but the true Rancho's father said that he said that he is his son Rancho so he study until college as Rancho
So the true Rancho give the address of the fake Rancho. When the two was on their way to the fake Rancho's house the true Rancho saw that the urn do not have ashes. He was tricked by the two. The last part I have watch is they are drinking and they are having fun
