Bus Systems Supporting Multiple Peripherals
As the number of potential peripherals grew using an expansion card for every peripheral became increasingly impossible This has led to the introduction of bus systems designed specifically to support multiple peripherals Common examples are the SATA ports in modern computers which allow a number of hard drives to be connected without the need for a card However these highperformance systems are generally too expensive to implement in lowend devices like a mouse This has led to the parallel development of a number of lowperformance bus systems for these solutions the most common example being Universal Serial Bus All such examples may be referred to as peripheral buses although this terminology is not universal

USB flash drive
A USB flash drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface USB flash drives are typically removable and rewritable and physically much smaller than a floppy disk Most weigh less than 30 g As of September 2011 drives of up to 256 gigabytes (GB) are available Storage capacities as large as 2 terabytes are planned with steady improvements in size and price per capacity expected Some allow up to 100000 writeerase cycles depending on the exact type of memory chip used and a 10 year shelf storage time
USB flash drives are often used for the same purposes for which floppy disks or CDROMs were used ie for storage backup and transfer of computer files They are smaller faster have thousands of times more capacity and are more durable and reliable because they have no moving parts Until about 2005 most desktop and laptop computers were supplied with floppy disk drives but floppy disk drives have been abandoned in favor of USB ports

Digital Technology of Copy Machine
There is an increasing trend for new photocopiers to adopt digital technology thus replacing the older analog technology With digital copying the copier effectively consists of an integrated scanner and laser printer This design has several advantages such as automatic image quality enhancement and the ability to build jobs (that is to scan page images independently of the process of printing them) Some digital copiers can function as highspeed scanners such models typically offer the ability to send documents via email or to make them available on file servers
A great advantage of digital copier technology is automatic digital collation For example when copying a set of 20 pages 20 times a digital copier scans each page only once then uses the stored information to produce 20 sets In an analog copier either each page is scanned 20 times (a total of 400 scans) making one set at a time or 20 separate output trays are used for the 20 sets

Smartphone
To really understand what a smartphone is (and is not) we should start with a history lesson In the beginning there were cell phones and personal digital assistants (or PDAs) Cell phones were used for making callsand not much elsewhile PDAs like the Palm Pilot were used as personal portable organizers A PDA could store your contact info and a todo list and could sync with your computer
Eventually PDAs gained wireless connectivity and were able to send and receive email Cell phones meanwhile gained messaging capabilities too PDAs then added cellular phone features while cell phones added more PDAlike (and even computerlike) features The result was the smartphone

What does HTML stand for
HTML is an abbreviation of HyperText Markup Language which is already more than you need to know at this stage However for the sake of good order let us explain in greater detail
· Hyper is the opposite of linear In the good old days when a mouse was something the cat chased computer programs ran linearly when the program had executed one action it went to the next line and after that the next line and so on But HTML is different you can go wherever you want and whenever you want For example it is not necessary to visit MSNcom before you visit HTMLnet
· Text is selfexplanatory
· Markup is what you do with the text You are marking up the text the same way you do in a text editing program with headings bullets and bold text and so on
· Language is what HTML is It uses many English words
HTML代表什？
HTMLHyperText Markup Language（超文表示语言）缩写形式超出现阶段应该知道容学序详解释
Hyper线性相反早时候老鼠猫追逐象——计算机程序线性运行：程序执行动作移动行然行等等HTML样时候想方例没必访问HTMLnet前先访问MSNcom网站

Bus Systems Supporting Multiple Peripherals
As the number of potential peripherals grew using an expansion card for every peripheral became increasingly impossible This has led to the introduction of bus systems designed specifically to support multiple peripherals Common examples are the SATA ports in modern computers which allow a number of hard drives to be connected without the need for a card However these highperformance systems are generally too expensive to implement in lowend devices like a mouse This has led to the parallel development of a number of lowperformance bus systems for these solutions the most common example being Universal Serial Bus All such examples may be referred to as peripheral buses although this terminology is not universal

USB flash drive
A USB flash drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface USB flash drives are typically removable and rewritable and physically much smaller than a floppy disk Most weigh less than 30 g As of September 2011 drives of up to 256 gigabytes (GB) are available Storage capacities as large as 2 terabytes are planned with steady improvements in size and price per capacity expected Some allow up to 100000 writeerase cycles depending on the exact type of memory chip used and a 10 year shelf storage time
USB flash drives are often used for the same purposes for which floppy disks or CDROMs were used ie for storage backup and transfer of computer files They are smaller faster have thousands of times more capacity and are more durable and reliable because they have no moving parts Until about 2005 most desktop and laptop computers were supplied with floppy disk drives but floppy disk drives have been abandoned in favor of USB ports

Digital Technology of Copy Machine
There is an increasing trend for new photocopiers to adopt digital technology thus replacing the older analog technology With digital copying the copier effectively consists of an integrated scanner and laser printer This design has several advantages such as automatic image quality enhancement and the ability to build jobs (that is to scan page images independently of the process of printing them) Some digital copiers can function as highspeed scanners such models typically offer the ability to send documents via email or to make them available on file servers
A great advantage of digital copier technology is automatic digital collation For example when copying a set of 20 pages 20 times a digital copier scans each page only once then uses the stored information to produce 20 sets In an analog copier either each page is scanned 20 times (a total of 400 scans) making one set at a time or 20 separate output trays are used for the 20 sets

Smartphone
To really understand what a smartphone is (and is not) we should start with a history lesson In the beginning there were cell phones and personal digital assistants (or PDAs) Cell phones were used for making callsand not much elsewhile PDAs like the Palm Pilot were used as personal portable organizers A PDA could store your contact info and a todo list and could sync with your computer
Eventually PDAs gained wireless connectivity and were able to send and receive email Cell phones meanwhile gained messaging capabilities too PDAs then added cellular phone features while cell phones added more PDAlike (and even computerlike) features The result was the smartphone

What does HTML stand for
HTML is an abbreviation of HyperText Markup Language which is already more than you need to know at this stage However for the sake of good order let us explain in greater detail
· Hyper is the opposite of linear In the good old days when a mouse was something the cat chased computer programs ran linearly when the program had executed one action it went to the next line and after that the next line and so on But HTML is different you can go wherever you want and whenever you want For example it is not necessary to visit MSNcom before you visit HTMLnet
· Text is selfexplanatory
· Markup is what you do with the text You are marking up the text the same way you do in a text editing program with headings bullets and bold text and so on
· Language is what HTML is It uses many English words
HTML代表什？
HTMLHyperText Markup Language（超文表示语言）缩写形式超出现阶段应该知道容学序详解释
Hyper线性相反早时候老鼠猫追逐象——计算机程序线性运行：程序执行动作移动行然行等等HTML样时候想方例没必访问HTMLnet前先访问MSNcom网站
Text 解释性
