Information literacy Knowing how to find data from several sources, select relevant material, analyse and organise it into a form that can be used to make Computers have become the tools people use to access and manage Information technologists are people who analyse and design the What is a computer? Tradition definitions of computers include • A machine that accepts data and processes it into use • A computer is a binary, digital, electronic, stored program • While a computer is commonly a digital machine, analogue machine do An electronic device, operating under the control of instructions stored in its own memory unit, that can accept data (input), process data arithmetically and logically, produce results (output) from the processing and stores results for future Many computers receive and send data (communicate) across networks LAN and W A computer system consists of hardware and What is hardware? Hardware Hardware is physical devices or components that can be physically handled – you can thou Input Devices Input devices convert data that humans collect into coded electrical signals that a computer can The central processing unit The electronic processing takes place in the CPU The CPU consists of • A control unit that controls all of the computer’s functions and an • Arithmetic and logical unit (ALU) that performs any calculation Memory Memory holds all programs and What is RAM currently open?

终端录用控制:结构问题和性能一个基於测量的录用控制网路伺服器
在1972年， IBM推出了灵活的软磁盘作为一个中型载货节目到电脑主机由于磁盘这么灵活的，他们被戏称为软盘。他们是物美价廉，规模小，易于处理，存储，并通过发送邮件。大多数的计算机都至少有一个软盘驱动器。软盘，又称为软盘，有两种规格： 5 25英寸。为MS - DOS的基于计算机， 5英寸磁盘，可在720千字节（双-密度） ， 1 44兆字节（高-密度），以及 88兆字节（扩展-密度）的能力。该25英寸磁盘有一个密度的48铁轨每英寸，而高密度磁盘有一个密度的96铁轨每英寸。几乎所有的5英寸软盘的密度135tracks每英寸。最早型号的软盘被单一片面的。加上另一个读/写头在磁盘驱动导致使用双面软盘，并增加一倍的容量磁盘。今天，所有软盘是双面的如果你研究了5英寸的软盘上，你会看到一个金属套涵盖读/写插槽。当你插入磁盘到磁盘到磁盘驱动器，金属套幻灯片回来，揭露读/写插槽。读/写头的软盘驱动器，可以清楚自己的定位超过特定的轨道。由于金属套筒和僵化的塑料外壳， 5英寸软盘是那么容易受到损害比25英寸软盘。 利用档案或程式，是在软碟上，你必须先插入磁盘到软盘驱动器软盘驱动器通常被称为甲驱动器和乙驱动器。看看哪个驱动器是甲或者乙有译不正之处见谅!
In 1972, IBM introduced flexible diskettes as a medium for loading programs into mainframe Because the disks were so flexible, they were nicknamed floppy They are inexpensive, small, and easy to handle, store, and send through the Most computers have at least one floppy disk Floppy disks, also called diskettes, are available in two sizes: 5 and 25 For MS-DOS based computers, the 5-inch disks are available in 720-kilobyte (double - density), 44-megabyte (high - density), and 88-megabyte (extended - density) The 25-inch disks have a density of 48 tracks per inch, whereas high-density disks have a density of 96 tracks per Almost all 5-inch floppy disks have a density of 135tracks per The earliest models of floppy disks were single- The addition of another read/write head in the disk drive led to the use of double-sided floppy disk, and doubled the capacity of the Today, all floppy disks are double- If you examine a 5-inch floppy disk, you will see that a metal sleeve covers the read/write When you insert the disk into a disk into a disk drive, the metal sleeve slides back, exposing the read/write The read/write head of the floppy disk drive can position itself over specific Because of the metal sleeve and the rigid plastic casing, the 5-inch floppy disk is less vulnerable to damage than the 25-inch floppy To use the files or programs that are on a floppy disk, you must first insert the disk into a floppy disk Floppy disk drives are commonly referred to as the A drive and the B Check your computer manual to see which drive is A and which is B
What Is Grid Storage? Based on current and proposed products, it appears that a grid storage system should include the following: Modular storage arrays: These systems are connected across a storage network using serial ATA The systems can be block-oriented storage arrays or network-attached storage gateways and Common virtualization layer: Storage must be organized as a single logical pool of resources available to Data redundancy and availability: Multiple copies of data should exist across nodes in the grid, creating redundant data access and availability in case of a component Common management: A single level of management across all nodes should cover the areas of data security, mobility and migration, capacity on demand, and Simplified platform/management architecture: Because common management is so important, the tasks involved in administration should be organized in modular fashion, allowing the autodiscovery of new nodes in the grid and automating volume and file Three Basic Benefits Applying grid topology to a storage network provides several benefits, including the following: R A well-designed grid network is extremely Rather than providing just two paths between any two nodes, the grid offers multiple paths between each storage This makes it easy to service and replace components in case of failure, with minimal impact on system availability or P The same factors that lead to reliability also can improve Not requiring a centralized switch with many ports eliminates a potential performance bottleneck, and applying load-balancing techniques to the multiple paths available offers consistent performance for the entire S It’s easy to expand a grid network using inexpensive switches with low port counts to accommodate additional servers for increased performance, bandwidth and In essence, grid storage is a way to scale out rather than up, using relatively inexpensive storage building

都好写。自己查一些论文，参考一下，怎么着也能编出一篇。如果想免费下载文献，请到我的百度博客看下，会不断更新一些能用的免费国内外图书馆的帐号。我当时毕业时，就是在网上的一个愚愚学园（下面文章里有学园地址）找了一些帐号，才能下载文献，完成了论文。我也在我的百度博客里也会更新一些以用的帐号。可以去找找试试。
校园内部合理化局域网设置的研究俺们当年就有人做这个题目
专科还是本科
计算机方面的技术我理解
说实话啊！现在的导师真的是对毕业设计提供的题目不负责任！你这四个题目，后两个估计是导师给别人做的项目！前两个是导师比较感兴趣的技术！如果你时间来不及了！建议你搞个图书馆什么的管理系统！这种论文资料很多，多下点凑凑就好了！（别原封不动）
很多设计希望能帮你
计算机方面的技术我理解
这个看你熟悉什么方向的去定，你可以去看看 51开源

计算机科学的毕设可能是最容易过的了， 因为只要找到一份网站或者管理系统个代码, 顺便写个论文就行, 参考资料极多比如课程管理系统, 学籍管理系统, 如果有要求的话可以拿SSH框架实现一些比较复杂的业务比如电商系统，网上订餐系统, 外卖系统, 这些能用于实际业务的几乎是个人能做的最复杂的业务了, 如果自己喜欢技术的话, 可以尝试做一下可以 look at my name, 可以找到很多项目的源码, 可以自己选一下, 希望能够采纳
这个看你熟悉什么方向的去定，然后就是看你熟悉那种语言，比如：c#，java，PHP，c，c++等等还有就是功能那些都是需要确定好的，然后就是框架那些了，一般框架就有MVC，ssm，ssh等等我的建议是你最好选择网站或者系统类的选题为佳
