`什麼是 Linux 引導載入程式`。
載入程式(bootloader),也稱為引導載入程式或引導管理器,是一種計算機程式,負責引導計算機。 當計算機關閉時,其軟體,包括操作系統、應用程式程式碼和數據,仍儲存在非易失性儲存器中。當計算機開機時,通常沒有操作系統或其載入程式儲存在隨機訪問儲存器(RAM)中。計算機首先執行儲存在只讀儲存器(ROM,以及後來的EEPROM、NOR快閃記憶體)中的一個相對較小的程式以及一些所需的數據,以初始化RAM(特別是在x86系統上),訪問非易失性裝置(通常是塊裝置,例如NAND快閃記憶體)或裝置,從中可以將操作系統程式和數據載入到RAM中。 一些早期的計算機系統,在接收到來自人類操作員或外圍裝置的引導訊號后,可能會將一些非常少量的固定指令載入到特定位置的儲存器中,初始化至少一個CPU,然後將CPU指向指令並開始執行。這些指令通常會從某些外圍裝置(可能由操作員進行選擇)開始輸入操作。其他系統可能會直接向外圍裝置或I/O控制器發送硬體命令,以導致執行極其簡單的輸入操作(例如「將系統裝置的零扇區讀入記憶體,從位置1000開始」),從而有效地將少量的引導載入程式指令載入到記憶體中;然後可以使用I/O裝置的完成訊號來啟動CPU執行指令。 較小的計算機通常使用不太靈活但更自動化的引導載入程式機制,以確保計算機快速啟動並具有預定的軟體配置。例如,在許多臺式計算機中,引導過程始於CPU在預定義地址(例如IBM PC或IBM PC相容機的BIOS)執行ROM中包含的軟體(某些CPU,包括英特爾x86系列,設計為在重置后執行此軟體而不需要外部幫助)。此軟體包含基本功能,以搜索有資格參與引導的裝置,並從最有前途的裝置的特殊部分(最常見的是引導扇區)載入一個小程式,通常從固定的入口點開始,例如扇區的開頭。
引導加載程序是用機器代碼編寫的程序,在引導過程中將操作系統加載到 RAM 中。
What is linux Bootloader
A bootloader, also spelled as boot loader or called boot manager and bootstrap loader, is a computer program that is responsible for booting a computer. When a computer is turned off, its software including operating systems, application code, and data‍—‌remains stored on non-volatile memory. When the computer is powered on, it typically does not have an operating system or its loader in random-access memory (RAM). The computer first executes a relatively small program stored in read-only memory (ROM, and later EEPROM, NOR flash) along with some needed data, to initialize RAM (especially on x86 systems), to access the nonvolatile device (usually block device, eg NAND flash) or devices from which the operating system programs and data can be loaded into RAM. Some earlier computer systems, upon receiving a boot signal from a human operator or a peripheral device, may load a very small number of fixed instructions into memory at a specific location, initialize at least one CPU, and then point the CPU to the instructions and start their execution. These instructions typically start an input operation from some peripheral device (which may be switch-selectable by the operator). Other systems may send hardware commands directly to peripheral devices or I/O controllers that cause an extremely simple input operation (such as "read sector zero of the system device into memory starting at location 1000") to be carried out, effectively loading a small number of boot loader instructions into memory; a completion signal from the I/O device may then be used to start execution of the instructions by the CPU. Smaller computers often use less flexible but more automatic boot loader mechanisms to ensure that the computer starts quickly and with a predetermined software configuration. In many desktop computers, for example, the bootstrapping process begins with the CPU executing software contained in ROM (for example, the BIOS of an IBM PC or an IBM PC compatible) at a predefined address (some CPUs, including the Intel x86 series are designed to execute this software after reset without outside help). This software contains rudimentary functionality to search for devices eligible to participate in booting, and load a small program from a special section (most commonly the boot sector) of the most promising device, typically starting at a fixed entry point such as the start of the sector.
A bootloader is a program written in machine code that loads the operating system into RAM during the boot process.

告訴我美國的各種道路型別?
美國的公共道路系統主要由高速公路和地方道路組成。美國交通部聯邦公路管理局 (FWHA) 根據速度限制、路線長度和間距等屬性創建的功能對道路進行分類。根據道路功能,我們可以將道路分為以下幾類。 1. 州際公路和乾線系統 2. 其他動脈 3. 收藏家 4. 當地人 州際公路系統是道路功能分類系統的頂端。其中包括速度限制最高的高速公路和高速公路,允許長途旅行而不會出現大量中斷。它們是使用精確的標準、標牌並考慮安全因素建造的。它們有時也被稱為主幹道路,因為它們提供了美國各地區的重要連接。 95 號州際公路或 I-95 是美國東海岸的此類高速公路的一個例子,從佛羅里達州延伸到緬因州。主要幹線系統還包括美國高速公路,為沒有州際公路支持出行的地區提供連接。 其他幹道還包括高速公路和高速公路,它們補充了上述州際公路系統。他們的速度限制稍低一些。它們通常連接城市和市區。將它們視為小型高速公路。例如,北卡羅來納州 55 號高速公路 (NC-55) 是連接北卡羅來納州多個地區和城市地區的主要州高速公路幹線。 收集器對於使用地方道路與適用的州際高速公路連接城市人口至關重要。它們有更多的中斷並且長度較短。它們的速度限制也較低(30-35 英里/小時)。這些可以包括連接地方道路與乾線高速公路的國道。 最後,地方道路提供社區、地區、農場和其他地方之間的連接。它們構成了美國道路系統的大部分。
Tell me about the various road types in USA?
The public road system in United States of America is primarily made up of Highways and Local Roads. The United States Department of Transportation's Federal Highway Administration (FWHA) classifies roads based on functions which are created based on attributes such as speed limits, route length and spacing. Based on the road functions we can categorize roads into the following categories. 1. Interstates and Arterial System 2. Other Arterials 3. Collectors 4. Locals The interstate system is the at the top of road function classification system. They include Highways and Freeways with the highest speed limits and which allow for long distance travel without a lot of interruption. They are constructed using precise standards, signage and with safety considerations. They are also sometimes referred to as Arterial roads as they provide vital connectivity across regions in America. Interstate 95 or I-95 is an example of one such highway in the east coast of the United States which runs from Florida to Maine. The Principal Arterial system also comprises of U.S. Highways, which provide connectivity across regions which do not have an Interstate to support travel. Other Arterials also include freeways and highways which supplement the Interstate system explained above. They have a slightly lesser speed limits. They typically connect cities and urban areas. Consider them as being minor highways. As an example, North Carolina Highway 55 (NC-55) is a primary state highway artery connecting multiple regional and urban areas in the state of North Carolina. Collectors are critical for connecting urban population using local roads with the Interstate highways where applicable. They have more interruptions and are shorter in lengths. They also have lesser speed limits (30-35 mph). These can comprise of State highways which connect local roads with the Arterial highways. Finally local roads provide connectivity between communities, regions, farms and other local areas. They form the lion's share of the United States road system.

What is one-child policy?
The term one-child policy refers to a population planning initiative in China implemented between 1980 and 2015 to curb the country's population growth by restricting many families to a single child. That initiative was part of a much broader effort to control population growth that began in 1970 and ended in 2021, a half century program that included minimum ages at marriage and childbearing, two-child limits for many couples, minimum time intervals between births, heavy surveillance, and stiff fines for non-compliance. The program had wide-ranging social, cultural, economic, and demographic effects, although the contribution of one-child restrictions to the broader program has been the subject of controversy.

什麼是鐳射,它是由誰發明的?
鐳射是一種通過光學放大過程發射電磁輻射的裝置。鐳射一詞起源於「光的受激輻射放大」,是一個首字母縮寫詞。第一臺鐳射器是由西奧多·邁曼在休斯研究實驗室于1960年建造的,基於查爾斯·湯斯和阿瑟·萊納德·肖洛的理論工作。 鐳射與其他光源的不同之處在於它發射的光是相干的。空間相干性使鐳射能夠聚焦到一個小點,實現鐳射切割和光刻等應用。空間相干性還使鐳射束在長距離上保持窄,實現鐳射指針和鐳射雷達等應用。鐳射還可以具有高時間相干性,使它們能夠發射具有非常窄的光譜的光。或者,時間相干性可以用來產生具有寬譜但持續時間短至飛秒的超短脈衝光。 鐳射被用於光碟驅動器、鐳射印表機、條形碼掃描器、DNA測序儀器、光纖和自由空間光通訊、半導體晶片製造(光刻)、鐳射手術和面板治療、材料切割和焊接、軍事和執法裝置用於標記目標和測量距離和速度,以及用於娛樂的鐳射照明顯示。藍色到近紫外線的半導體鐳射器也已被用來代替發光二極管(LED)作為激發螢光的白光源。這使得由於鐳射的輻射度更大,發射面積可以小得多,並避免了LED所遭受的下降;這樣的裝置已經在一些汽車大燈中使用。
激光器是一種從電磁輻射源發射光的裝置。第一台激光器由休斯研究實驗室的 Theodore Maiman 於 1960 年根據 Charles H. Townes 和 Arthur Leonard Schawlow 的理論工作製造而成。 激光發射某種類型的光。相干的光。相干性可以在空間或時間上進行測量。空間相干性使激光束在遠距離內保持狹窄。時間相干性可用於產生超短光脈衝。 激光應用的一些例子包括光盤驅動器、激光打印機、條形碼掃描儀、光纖和光刻
What is a laser and who created it?
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of light with a broad spectrum but durations as short as a femtosecond. Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, and free-space optical communication, semiconducting chip manufacturing (photolithography), laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment. Semiconductor lasers in the blue to near-UV have also been used in place of light-emitting diodes (LEDs) to excite fluorescence as a white light source. This permits a much smaller emitting area due to the much greater radiance of a laser and avoids the droop suffered by LEDs; such devices are already used in some car headlamps.
