Alex: Hi, it's been almost two years since we last met each other! How were you doing? Mike: Until recently, I was frustrated that I could not meet my friends at university, but I was able to spend more time with my family, so I was okay. By the way, how did you like the online classes? Alex: Personally, I did not like them. It was difficult for me to maintain my concentration at home. Also, I could not resist the temptation of using my smartphone, because there was no supervisor at home who checked whether I was working hard or not. Mike: If you use your phone during class, the professor will definitely tell you off! Mo Alex: Another reason why I prefer in-person classes is that I can ask questions or have discussions with my friends. In the Pre-covid-19 era, when I had questions, I went up to my friend Thomas, one of the best students in our faculty and he taught me everything that I did not understand. Mike: That was a huge issue for me as well. If I have questions piled up, then I am more likely to dislike the subject and have more anxiety towards it. So, my friends and I decided to have meetings online on a regular basis and this helped me to worry less about online learning. Alex: That was really ( 1 ) of you, I should have done that! So, are you in favor of online learning? Mike: Yes, although I have less face-to-face interaction with friends, I like online learning more because I do not have to spend a lot of time commuting to school. I live far away from university and it takes two hours for me to get here by train. B(A) Alex: Really! I did not know that, what time do you wake up? Mike: I usually wake up at 5 am. Alex: That's so early! What do you do on the train? Mike: I just do netsurfing and I do not feel that I use my time productively on the train. If we can continue to take online classes wherever we want, we can get more flexibility in our schedules, We won't have take the time to commute to the university to attend classes, or if we like it, we may even be able to watch lecture videos on our phones while traveling by train. Alex: I understand your opinion, but didn't you have any technical problems? Mike: I only had a few. Besides, most of the professors posted recorded videos of lectures after class. So, I watched the recordings when I missed some parts. Furthermore, I could study at my own pace and the videos allowed me to digest what I had learned. Alex: That's a good point, but it had an adverse effect on my learning. Mike: How? Alex: I started skipping my online classes because I thought I could just watch those recorded videos later.

8ビットのデータの中にある1の個数を偶数個にするか、奇数個にするかあらかじめ決めておき、1または0を1ビット付加する場合に、なぜ誤りを訂正できないのかがわかりません。教えてくださいm(_ _)m

5 誤り検出符号 データを送受信する際に, 通信回線のノイズの影響を受け, データの 0と1が変わってしまうと,送ったデータと受け取ったデータが異なる こととなり不都合が生じる。このデータの反転 (誤り) を検出するために, 各ビットの変化を確認するための情報を送信データに加えることで誤り を検出する方法がある。 この付加データを誤り検出符号 (パリティビット) という。 10 parity bit 例えば,7ビットの送信データに, パリティビットを1ビッ ト追加して, 合計8ビットとして送信するとする。 この8ビッ トのデータの中にある 「1」 の個数を, 偶数個にするか奇数個に するかをあらかじめ決めておき, 「1」または「0」を1ビット付 加する。ただし,この方法では, 1ビットの反転は検出できる が、 2ビットの反転を検出することはできない。 また誤りを検 出しても,誤りを訂正することまではできないので, データの 20 再送を要求する。 0 15 ③誤りの検出だけでなく誤り 検出と誤り訂正の両方を行う 技術もある。 ④1を偶数個にするパリティ ビットを偶数パリティ, 奇数 個にするパリティビットを奇 数パリティという。 データ: 0010101」の場合 1 を付加 00101011 - 「1」の個数が 偶数個になる データ: 0101011」の場合 ···0を付加 01010110 「1」の個数は 偶数個のまま Network 回答 00 01

5. John seemed (to be) satisfied with the results of his experiment. 解説 1.「困ったことは (人) が~することだ」と考え,〈The trouble is that S' + V'> で表す。 be in a bad mood 「機 嫌が悪い」。 2. 「QをCのままにして(放って) おく」は〈leave O+C)を用い る。 ｢~している状態に」 と進行中の動作を表すため、Cは 現在分詞にする。 run (エンジン・機械などが) 動く」。 3. 「インターネットをサーフィンする, 閲覧すること」と考え, 動名詞または不定詞 to surf [browse] the Internet で表す が,すでに行われている事柄なので動名詞を用いるのが普 通。 4. 「退屈している」 は受動態 be bored で表される。 be 動詞を 「~になる」と動作を表す get に置き換えて、get bored 「退屈する」とすると SVCの文型になる。 not at all 「まったく [全然] ~ない」。 5.「満足している」は受動態 be satisfied で表される。 be 動 詞を「~のように見える」 seem に置き換える。 to be はあ ってもなくてもよい。 satisfied の代わりに happy や pleased を用いてもよい。 3
