Tablet computers more and more worldwide thanks to its practicality. Variety of systems used were varies. There are IOS for the iPad, there are the BlackBerry is a supporter of the tablet computer latest release, Playbook. However, the tablet that is currently circulating in the market instead using the Android operating system. This is understandable, given the homemade operating system Google is open source and supported by many computer vendors tablet computers. The average computer Android tablet computer currently available using the Android operating system 2.1 (Eclair) and 2.2 (Froyo). In fact, some of them are still using a version of Donut. Google itself actually did not design Eclair and Froyo for use in computer tablet computers. But with the firmware modification by the vendor, both operating systems can be used in digital slate. For use on a tablet computer, Google itself Honeycomb released version which is intended in large sailing gadgets.

Many options Tablets
There are many options Android-based tablet. A well-known example Samsung Galaxy Tab and Dell
Streak. Another option is the output of products Archos, Huawei, Acer, Asus, to Toshiba. brand Local was also there as Tabulet, Toshiba, and also Zyrex. Interestingly enough attention is imitator “iPad” and “Galaxy” Android applying China’s production is priced by cheap.This proves that the Android tablet a favorite because the choice is quite a lot. Android tablet is also a choice of mobile workers who want a more practical gadgets than the already tiny netbook.]

The next question then arises: whether the tablet operating system supports the activities of mobile workers? Of course. A large-screen Android tablet even more convenient to use to manage documents.

Basics

Sliding Window is the method of flow control TCP uses. The algorithm basically places a buffer between the application and the network data flow. The purpose of sliding window is to prevent from the sender to send too many packets to over flow the network resource or the receiver’s buffer. The “sliding window size” is the maximum amount of data we can send without having to wait for ACK. TCP achieve the flow control by using the sliding Window algorithm which takes into consideration 2 important parameters. The first one is the receiver advertised window size which basically tells the sender what is the current buffer of TCP receiver, the second parameter is congestion window which control the number of packets a TCP flow may have in the network in any given time.

Receiver Advertised Window

The Receiver Advertised Window (adwn) is the buffer size sent in each ACK from TCP receiver to TCP sender. The TCP header uses a 16 bit field to report the receive window size to the sender. Therefore, the largest window that can be used is 2^16=65k bytes..

Congestion Window

Congestion Window (cwnd) controls the number of packets a TCP flow may have in the network in any given time. cwnd is dynamically adapting to changing network condition Slow-start is one of the algorithms that TCP uses in its quest to control congestion inside the network and it is also known as the exponential growth phase. Slow-start works by increasing the TCP congestion window each time the ACK is received. it increases the window size by the number segments acknowledged. If a loss event occurs, TCP assume this is due to network congestion and takes step to reduce the offered load on the network.

When TCP reaches a certain threshold (also known as sstrsesh) it will enter the linear growth, Congestion avoidance. in our sliding window demo the threshold is fixed on 10. At this point, the window is increased by segmentSize*segmentsize/cwnd for each receiving ACK. Sliding Window Operation First, the sender creates a sequence number for each frame as it is transmitted. Throughout the communication, it maintains the send window size, the last acknowledgment received, and the last frame sent. To ensure that the window does not overflow, the sender ensures that the window size is greater than the sequence number of last frame sent minus the sequence number last acknowledgment received. When the sender transmits a frame, it increments the sequence number by one and starts a timer. The sequence number is sent with the frame so that the receiver can detect if a frame is received out of order. The sender continues sending frames until the buffer of unacknowledged frames is as large as the send window size.The sender then waits until it receives acknowledgments before transmitting more frames.

Whenever the sender receives an acknowledgment from the receiver, it increments the value of the last acknowledgment received, thereby sliding the “sliding window” to the right. If the timer for the frame expires before the sender receives an acknowledgment for the frame, it assumes that the frame was lost and retransmits it. The receiver holds onto three pieces of information as well: the receive window size, the last frame received, and the next frame to acknowledge. When a frame arrives, the receiver evaluates the frame to determine if it falls within the receiver’s window. The size of the receiver’s window is determined by the number of frames the receiver can buffer before overflowing. The receiver can not process frames received out of order. A frame is out of order if a gap exists between the sequence numbers of the newly received frame and that of the last frame received. If a frame is received with a sequence number that results in a gap larger than the size of the receiver’s window, the frame is determined to be outside the window and is discarded. If a frame is received with a sequence number that is lower than or equal to that of the last frame received, this frame is by definition outside the window and must be a duplicate. It is also discarded. Packets with sequence numbers that fall within the window are accepted and put into the buffer. After accepting the frame, the receiver again checks the sequence number to determine if the frame was received in the correct order. The receiver compares the incoming frame’s sequence number to next frame to acknowledge sequence number. If they match the receiver sends an acknowledgment. The next frame to acknowledge and last frame received are both incremented, thus sliding the window along. wikipedia

Simulation

The demo shows a simulation of sliding window with advertised window set to 10. The sender starts to transmit in slow start mode , after it reaches the threshold it goes into congestion avoidance. The sender keep the pointer to Last Frame Sent (LFS) and Last ACK Received (LAR). The size of the sliding window is changing based on the minimum of congestion window(cwnd) and advertised window. Use the tool tip over the hot points for more details.

CALIFORNIA – Promoted After the previous game (paid advertisements tweet on Twitter) only appear in the sidebar of the user, starting the week Twitter announced that the service in the next few weeks will be present in the user timeline.

As quoted by Mashable, Friday (29/07/2011), the Twitter announced that it will Promoted game will start rolling with a number of already existing advertisements.

This step is a big step for Twitter, because until now, only appears Promoted Tweet on Twitter search or the side-bar with a Trending Topic concurrent users.

“From the beginning, our philosophy on advertising is quite simple: we give priority to the user and create products that enrich the experience of every user of Twitter,” wrote the Twitter on his blog.

Later Promoted Tweet will be in the “on or near the” Twitter timeline. Party microblogging site also says that later users can also remove the tweet of the timeline with just one click.

Some advertisers are already working with Twitter for Promoted Tweets are companies that have a lot of Twitter followers, namely Starbucks, JetBlue, Gatorade, Groupon, HBO and Sephora. Several non-profit organizations like The American Red Cross will also promote the service.

Nonetheless, some parties hope that this service appears only in the timeline that follows the user accounts of related companies, not to impress as spam or ‘nyampah’ in the timeline of others.
