I personally think that teamwork and communication are very important during CA1, CA2 and CA3. We need to cooperate well, discuss amiably with one another to find a suitable solution for some of the challenges or obstacles faced in the process of accomplishing the task assigned to us by our teacher. One such example would be the games for our CA1, the aim of our first game was to score a ball into the bins which are of different colors and entitled us to different score. Our initial plan was to score
the molarity of the sucrose solution out the cells of potato. I predict that if the molarity of sucrose solution outside the cells is isotonic to the molarity of the sucrose inside the cells then there will be no change in weight of the potato disks. I predict this because if the molarities are isotonic inside and outside the cells then there will be a balanced osmotic movement of the water molecules from inside and outside hence there will be no change in weight. I also predict that if the
estimated to be about 100,000 light years. The galaxy has three main components: a disk, in which the solar system resides, a central bulge at the core and an all encompassing halo. The disk of our galaxy exhibits it’s spiral structure and is part of the prominent nuclear region which is part of a notable bulge/halo
electromagnetism makes possible the era of electronic communication to begin. 1862: Abbe Giovanna Caselli invents his "pantelegraph" and becomes the first person to transmit a still image over wires. 1873: Scientists May and Smith experiment with selenium and light, this opens the door for inventors to transform images into electronic signals. 1876: Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a "selenium camera"
television had already been invented by some inventors such as Paul Nipkow and John Logie Baird, but they had only created mechanical television with spinning disks or mirrors. Philo new that you could not spin disks fast enough to create a moving picture. He only knew of one thing that could; the electron. One day Philo was daydreaming while disk harrowing a potato field with a two horse team. Row by row by row. Suddenly he got an idea that if he could put lines of dots row by row on the television
vulnerable to the outside world (unless of course the system is isolated from the Internet). Another thing to think about is the fact that any data on any type of disk can be salvaged. So if a corrupt disk is discarded, the data can be recovered with the right tools. The same is true with computer hard drives, flash memory, compact Disks etc... There are actually people who recover data for their income. These people usually don't discriminate against one customer or another they just extract the
television devices were based on an 1884 invention called the scanning disk, patented by Paul Nipkow. This device was a large disk with holes on it, which spun in front of an object while a photoelectric cell recorded changes in light. Depending on the electricity transmitted by the photoelectric cell, an array of light bulbs would glow or remain dark. But Nipkow’s mechanical system could not scan and deliver a clear, live-action image. Many inventors hoped to perfect this. In 1921, a 14-year-old Mormon
Polarization Introduction: PART ONE: POLARIZATION Method 1: Two polarized disks were put into a grooved holder with their polarization axes lined up, and a bright red light emitting diode (LED) was placed on one side, and a light sensor was placed on the other side. Light intensity was measured as a function of the plastic rotating polarizer angle from 0 to 180 degrees. Science Workshop was used to measure the intensity for every 5-degree rotation (Fig 1). Method 2: The mineral calcite
lot of harm to it. It can potentially erase all the contents of the hard disk on the computer. Trojan horses hit a small number of people because they are discovered easily. Either the bulletin board would erase the file from the system or the people would send out messages to warn one another. The third reason was growth of floppy disks. Many programs could fit into a single floppy disk. Most computers did have hard disks so computers would just load everything off the floppy when switched on including
a computer and appropriate software .You can use a mouse to design it but it isn't very accurate so they usually type in the commands or use a tablet pc. [IMAGE] Cad allows very accurate and precise drawings to be achieved quickly and easily and it is very easy to make alterations to you project your designs can be stored on disks so you can take your work anywhere you go Cam stands for computer aided manufacture. Cad and Cam are mostly used together. Because cad designs the project
ROMs—which had to be purchased from Apple—were later eliminated by hackers and replaced with faster software ROMs (3.2).

a Ghost image from the Server and then redirects the image to other workstations, the Ghost Clients, through the use of TCP/IP settings over the network. The main advantage of Ghost Multicasting is that the downloading time is extremely shortened as only one PC is downloading the image off the Server which dramatically reduces the risk of heavy network traffic. The only disadvantage is that the PC chosen to be the Ghost Server has to have enough free hard drive space to store the image which will
costing millions of dollars in lost revenue. Software companies have used many different copy protection schemes. The most annoying form of copy protection is the use of a key disk. This type of copy protection requires the user to insert the original disk every time the program is run. It can be quite difficult to keep up with disks that are years old. The most common technique of copy protection requires the user to look up a word or phrase in the program's manual. This method is less annoying than other

It occurs when too many employees on a network are using a central copy of a program at the same time. Third, Internet piracy. This occurs when software is downloaded from the Internet where the same purchasing rules should apply to online software purchase as for those bought in traditional ways. Fourth, Hard Disk loading. It occurs when a business that sells new computers

magazines, encyclopedias, letter’s etc. The electronic medium that they are created, transmitted and stored on can be on magnetic media disks (standard 3.5-inch disk,) digitally on the Internet or on other electronic forms such as CD-ROM and DVD technology. These are two of the most frequently used as they can digitally store thousands of pages of information on a compact disk. Electronic publishing has made work easier for millions of people around the world as they can have millions of pages of information
characteristics. For example, consider Thomas's support of the development of the laser disk. Although it is a "palpably loss-making enterprise," (308), Thomas bankrolls its development because it produces "perfect still frames ... [which suit] his needs so admirably" (308). Certainly Adam Smith did not think of masturbation as being enlightened self-interest, though it is "the very raison d'être" of the laser disk as far as Thomas is concerned (308).

over a relatively limited area and connected by a communications link that enables any device to interact with any other on the network. LANs commonly include microcomputers and shared (often expensive) resources such as laser printers and large hard disks. Most (modern) LANs can support a wide variety of computers and other devices. Each device must use the proper physical and data-link protocols for the particular LAN, and all devices that want to communicate with each other on the LAN must use the
boot-record infectors infect executable codes found in certain system areas on a disk, which are not ordinary files. Not only are there two main classes of viruses, but there are also many different types. A virus can be classified as a boot sector virus, a program virus, a trojan horse virus, a macro virus, a memory resident virus, a stealth virus, or a polymorphic virus. A boot sector virus replaces the startup code on a disk with a modified version, which is loaded into the memory when the computer
