1. What is the difference between a. and a. Maximum Packet Lifetime The maximum packet lifetime (MPL) is how long a packet can exist in the network before being discarded. MPL must be long enough to ensure that both the packet and its acknowledgments have vanished. This prevents old duplicate packets and their acknowledgments from causing network confusion and errors. If the MPL is too short, a packet or its acknowledgment may remain in the network when the sequence number is reused, resulting in incorrect data being accepted.

2. What is the difference between a'smart' and a'smart'? Nagle's Algorithm for a Congested Network Nagle's algorithm reduces the number of small packets sent by a host by buffering and sending outgoing messages in groups. However, in a heavily congested network, this can result in increased latency as packets are delayed while the buffer fills. This additional delay can have a significant impact on the performance of real-time applications like video streaming and online gaming, which require timely data delivery. …show more content…
What is the difference between a'smart' and a'smart'? TCP Data less Packets TCP can send packets without data in some scenarios.

Probing: If the sender has not received an acknowledgment for an extended period of time, it may send a data-less packet to probe the receiver and determine its status. Keep-alive Messages: If a TCP connection has been idle for a long time, the sender may send a data-less packet to keep the connection active and prevent it from being dropped due to inactivity.

...Star One of the most common setup of networks is the “star topology”, being that every node within the network connects to a central network device. The central network device can be a hub, switch, or even a computer, and it also acts as a server to the nodes on the network. Some advantages to the star topology are the ease of adding another computer to the network and the networks continue to function normally when one network fails. The disadvantages are the cost is higher, the performance is determined by the central network device, and lastly if the central network device fails there is no back up so all networks fail. Bus The “Bus Topology” is a network setup in which each computer and network device are connected to a single cable. This type of setup is not good for large networks for many reasons. Some reasons are difficulty in troubleshooting individual devices and the entire network, the network can fail if the cable is damaged, and the more devices on the network slows down the entire network. In contrary to larger networks, this set up is perfect for smaller networks, because it requires less cable length and setting up the actual network is easier as well. Ring This network is mostly used in schools and offices, where the networks are smaller. In this setup the devices are connected to each other going in a circle shape, so that each packet must go around the circle until it reaches its destination. Data flows only in one direction at high speeds between...

...The reason for this project is based on the high risk of processing and storing customer personal information that can lead to a data breach which can become a high financial loss to the company if gone undetected. Regulatory recommends that financial institutions implement data security to minimize attacks and to implement security controls in areas that process personal, confidential customer information (FDIC.gov, 2014). This project will help with unauthorized data use and also assist in protecting the information if they ever have a data breach. The company’s security methodologies were put in place with minimal security in mind when they first implemented the online website. Since there is confidential customer information stored internally, there is a need to encrypt the information in storage. The goals of this project are to make sure customer data is secured from unauthorized use but also in making sure the solution does not cause any outages. The solution must align with the business users and not interrupt the application processes already in place. It must not disrupt the data in storage or cause slowed response time when users are retrieving information. The project objectives are to analyze the environment and recommend an encryption methodology that will work with the existing databases. Users will not know that encryption is applied and only authorized security personnel will have access to the encryption keys. The main element is to make sure that the information...

...3. The mechanism that is used to detect/avoid/correct data transmission collision in Layer 2 is called Carrier sense multiple access (CMSA). CMSA is a Media Access Control protocol that listens for signals (senses) on the network medium (carrier) before transmitting data. The rule is that only one device can transmit data at a time. Before a device begins to transfer data, CSMA will listen for any transmissions on the network. If CSMA notices there is a transmission, then CSMA will wait for that transmission to end in order to send a transmission. For Etherenet, Carrier Sense Multiple Access/Collision Detection (CSMA/CD) is used. In CSMA/CD, CSMA uses collision detection when two devices notice that the network is clear and begins to transmit at the same time which causes a collision. The collision is detected, the signals are dropped, and each device will wait a random time using a back off algorithm to send each of their signals again. For, WiFi, Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) is used. In CSMA/CA, collisions are trying to be prevented beforehand. A device will use a backoff counter when the network is being used. If the network is clear when the backoff counter reaches 0, the device will transmit. If the network is still being used, the backoff counter will reset and repeat the process until the...

Of the reported incidents in 2015 as per the report, 63% of proved date breaches involved weak, default or stolen passwords. These happen mostly in the Web application attacks, and the POS Intrusions. One simple thing that we ignore is that by maintaining static credentials, a user is luring the attacker for easy way of intrusion. Compare to other methodologies of hacking, a static password hacking is the easiest and most convenient way.

...Let us take the example of a communication system. One would like to send 4 bits of data (a bit is a binary digit, which is simply a logic variable that accepts only two values: “0” and “1”). These 4 bits of data will correspond to 16 different possible levels (0000 to 1111). If we associate a number to each combination, then we will have 16 numbers from 0 to 15 (if using hexadecimal base, we have then the following digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F). The probability to have each of one of the digits is then 1/16. Let us assume that we connect a microphone to a digital system that will encore the different sound levels over 4 bits, or 16 levels (this is called quantization), then before any sound is recorded, one cannot know, a priori, what will be the value in bits of the data to be collected....

...For example; ADC_Value = 980 which can be represented in binary as 1111010100. Upon right shifting this value we get 11110101 which makes 245 in decimal. On the receiving end, upon multiplying by 4, we get 980 which gets plotted. This technique produces a maximum error of +/-3 which is negligible. The ADC module converts the incoming values into a digital value and saves it in a dedicated register ADC10MEM. The value of this register is first copied into UCA0TXBUF (After being converted into 8-bit) in order to transmit it to the PC. It is kept in mind to clear the UCA0TXBUF and the Interrupt flag register each time after transmitting the value in order to ensure proper transmission of data. 6.4.2 TALKING TO PC 6.4.2.1 COM PORT A COM port, also...

...To connect a projector to computer, begin by selecting the type of cable you will be using (HDMI, VGA or USB). HDMI (High Definition Multimedia Interface) provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable. VGA (Video Graphic Array) cable is used to connect an analog PC monitor to a PC or laptop. VGA cables utilize an HD15 connector to connect the monitor and PC/laptop. USB (Universal Serial Bus) allows a person to connect an electronic device to a computer, used mostly to connect computers to peripheral devices such as cameras, camcorders, etc. Newer projector may have a DVI connector or optical connector. Once you have chosen the appropriate cable and have connected it to the computer and projector, windows 7 should automatically detect the projector and begin searching for the correct device drivers. If Windows 7 cannot find the device driver for the projector, it will give the option to search the internet or to insert a manufactures disc with the device drivers on it. Once the device drivers are installed you are ready to use the projector with Windows 7. Now that Windows 7 is ready to work with the projector, there are options on how to display the image.
