3. Answer the following questions. 1 What is the difference between UNIX and Linux? 2 3 4 Choose one of the words in italics in the text. What is the definition of the word you have chosen? What are the three levels of a Linux system? What are the two main functions of the kernel? [Reading Text] UNIX was initially developed by researchers at Bell Labs in the 1970s. Today, UNIX and its variants are widely used mainly on servers. By far, the most well- known UNIX-like operating system is Linux. Linux is available in different distributions which include the Linux kernel and different collections of software. These distributions have various user interfaces, many experienced users preferring the command-line interface, or shell. Linux distributions include a range of software including text editors. memory. While the mechanics of Linux and other Unix operating systems are complicated, the components of a Linux system can be grouped into three levels. The lowest level is the hardware, such as Central Processing Unit (CPU) and The next level is the kernel. It enables communication between hardware and software, by providing instructions to the CPU and other hardware. The programs that are running on the system, or processes, make up the top level known as the user space. Processes in user space generally only have access to a restricted amount of memory and operations, this is called user mode. The kernel runs in kernel mode which allows it unrestricted access to hardware resources. The kernel provides functions such as process management and memory management. A computer only has limited Random Access Memory (RAM) and processor cores. Process management allows the system to run multiple programs (processes) at the same time even if the CPU can only execute only a few processes at a time. Memory management allows applications to share the system's memory while avoiding potential issues such as memory leak. Included with the kernel are device drivers that provide an interface for applications to communicate with hardware, such as hard drives. System calls allow user processes to access features that are executed at kernel mode, for example creating new processes.

2022 P=HT 6. 次のお知らせを読み、 (1) ~ (2) のA~Dで適切なものに○をつけなさい。 [4×2=8] TO: All staff From: Erin Liner, Manager Date: July 15 Subject: Our survey Dear all. We have finished reviewing the data which we received from the recent customer satisfaction survey. I would like to share the most important findings, and how we can improve on certain areas of our work. Overall, customers were happy with the quality of our service. the helpfulness of our staff, and the range of products we offer. However, there were some negative comments which we can begin to work on. A common complaint was that there are not enough foreign titles in the store, especially Japanese comics. I will ask John Calman to research some of the most popular series and make sure we start carrying them from the fall. As Gita Pradesh spent her college years in Tokyo, I will ask her to assist. Better signage was another thing which people wanted. They spend a lot of time looking for the right section and it frustrates a lot of customers. This is something we can improve immediately, so I will speak to Alice Moore today about making the signs easier to see, and adding more if necessary. Finally, we got some comments about having a small cafe in the store. Nowadays, people want to have a coffee while reading or browsing, and it could be a new source of profit. Mario Venetti will make a report on the feasibility and deliver it next month. Thank you for all your efforts in making us the best we can be. Erin Liner Manager (1) What is the purpose of the e-mail? (A) To ask staff to create survey questions (B) To share details of customer feedback (C) To inform staff of recent changes (D) To invite staff to apply for new positions (2) Where does Ms. Liner most likely work? (A) At a café (B) At a movie theater (C) At a clothing shop (D) At a bookstore 以

Music During Surgery? (e) 2-37 Scientists have found that the soothing effect of music benefits patients having eye surgery. Studies show that those who listened to their choice of music during surgery had a significantly lower heart rate and blood pressure than patients who did not listen to music. Heart rate and blood pressure of all patients increased the morning of surgery.. However, these measures of cardiovascular stress dropped significantly in the music group within ten minutes of tuning in, and remained low throughout the surgery. The stress from surgery was lower among the music patients, but their ability to cope was higher. These ratings confirm the benefits of music during surgery. It has also been noted in other studies that surgeons who play music of their choice during surgery feel that it relieves stress and improves their performance. In the words of one researcher, “If music was a drug, everyone would want it. Patients like it. It's cheap and effective, and has no negative side effects." NOTES: soothing 「(神経や感情を)静める」 cardiovascular 「心 (臓)血管の」cardio は heart の意. side effect「(薬物などの)副作 用」

The Old Time Pain Reliever-Aspirin () 1-77 CD Aspirin is the most commonly used drug to relieve pain. People all over the world take this medicine. Aspirin was developed 100 years ago by Felix Hoffmann Bayer. It was used widely until the 1960s when its use declined because other medications had been developed. In 1985, researchers reported that aspirin could reduce the risk of a second heart attack by 20%. As a result of this finding, aspirin has regained its popularity. It is now recommended for the prevention of first heart attacks, especially among people who Researchers are also finding that aspirin may lower the risk of colon cancer and possibly lessen mental decline. Aspirin has some side effects, such as stomach upset and bleeding. It is important that patients understand these are at greatest risk. side effects and balance the benefits and risks of taking this drug. In the next hundred years we may find even more uses for aspirin. NOTES: colon cancer |結腸ガン」 stomach upset 「胃の不快感」

There are several reasons. First, medical researchers have shown that secondhand smoke, that is, the smoke from other people's cigarettes, causes cancer and other health problems. Third, I'm slightly allergic to smoke; therefore, my nose stuffs up when I smell tobacco smoke. If the smoke were car exhaust or burning trash, we would put out the fire and open the windows to get rid of the smoke. Second, it stinks. The smoke drifts away from the smoker and fills the room. However, the right of people to breathe pure air must always be put before the right of smokers to pollute that air. Whenever I smell strong tobacco smoke when lI'm in an enclosed space such as a room, train, or aircraft, I begin to get angry. Even if l am not sitting close to the smoker, my hair and clothes pick up the smell. Aml saying that all smoking should be banned? Of course not. Smokers have a right to smoke.
