Transcript: The Road Ahead Vector and BITMAPS Bitmap and Vector are different ways of storing an image as bitmaps use pixels but vectors use lots of lines to form an image Vector and Bitmaps Bitmaps Bitmaps Bitmap images are created from rows of pixels and if the image size is enlarged enough then the pixels can become visible Vectors Vectors vector images are made up of several lines that can be redrawn when manipulating the size of the image so the image does not become blurry Image resolution Image Resolution Image resolution is the detail that an image holds (the number of pixels in an image) Colour depth Colour depth colour depth is either the number of bits used to indicate the color of a single pixel in a bitmap image, or the number of bits used for each color component of a single pixel. file size file size is the measure of space a file takes up on a storage medium, such as a computer hard drive. File sizes can be measured in bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB) and terabytes (TB) How file size is affected Resolution Resolution A higher resolution increases the file size as more pixels need to be stored. A higher colour depth increases the file size of an image as more pixels are used for each colour section Colour depth Meta data Meta data is a set of data that describes and gives information about other data.

Transcript: The difference between client server networks and peer to peer networks Presented by Adam Obrycki Client server networks Client server networks The term client-server refers to a popular model for computer networking that utilizes both client hardware devices and servers, each with specific functions. The client-server model can be used on the Internet as well as local area networks. Examples of client-server systems on the Internet include Web browsers and Web servers. 1)Centralization, unlike P2P, where there is no central administration, here in this architecture there is a centralized control. Servers help in administering the whole set-up. Access rights and resource allocation is done by Servers. 2) Proper Management : All the files are stored at the same place. In this way, management of files becomes easy. Also it becomes easier to find files. 3) Back-up and Recovery possible : As all the data is stored on server its easy to make a back-up of it. Also, in case of some break-down if data is lost, it can be recovered easily and efficiently. While in peer computing we have to take back-up at every workstation. Advantages Advantages 1)Congestion in Network, too many requests from the clients may lead to congestion, which rarely takes place in P2P network. Overload can lead to breaking-down of servers. In peer-to-peer, the total bandwidth of the network increases as the number of peers increase. 2) Cost : It is very expensive to install and manage this type of computing. Disadvantages Disadvantages Peer to peer networks Peer to peer networks In its simplest form, a peer-to-peer network is created when two or more PCs are connected and share resources without going through a separate server computer. A P2P network can be an ad hoc connection—a couple of computers connected via a Universal Serial Bus to transfer files. 1) It is easy to install and so is the configuration of computers on this network, 2) All the resources and contents are shared by all the peers, unlike server-client architecture where Server shares all the contents and resources. 3) P2P is more reliable as central dependency is eliminated. Failure of one peer doesn’t affect the functioning of other peers. In case of Client –Server network, if server goes down whole network gets affected. Adavantages Adavantages 1) In this network, the whole system is decentralized thus it is difficult to administer. That is one person cannot determine the whole accessibility setting of whole network. 2) Security in this system has much more viruses, spywares,trojans, etc. 3) Data recovery or backup is very difficult. Each computer should have its own back-up system Disadvantages Disadvantages The difference The difference There’s a huge difference between client/server and peer-to-peer networks. For instance, a peer-to-peer network has no central server. Each workstation on the network shares its files equally with the others. There’s no central storage or authentication of users. Conversely, there are separate dedicated servers and clients in a client/server network. Through client workstations, users can access most files, which are generally stored on the server. The server will determine which users can access the files on the network.
