A user opens a Web browser and types in a URL that lists the name of a server. The user has never tried to send IP packets to this particular server before. Which of the following protocols will the PC need to
9/8/2013 SEC280 Case Study Week 1 Case Study: Ping Sweeps and Port Scans Ping sweeps and port scans are not an immediate threat to the company. While it may be used by an attacker to build a profile against the company, it can also be used by an administrator to gather information about the company. Although it is not an immediate threat, it should still be monitored for potential threats because it is a common way for hackers to attempt to break a network. In the following document, more will be discussed about what ping sweeps and port scans are and how they are used to gather information about a company’s network. What is a ping sweep and how does it work?

Complete the table below with descriptions of at least two different features of a telephone system and how / when they would be used.
Think that a communication protocol is like a Standard of Operations Manual (SOP). The Standard of Operations Manual (SOP) will keep everything organized. Everything will be described in detail on how everything works; otherwise, if there is no Standard of Operations Manual (SOP) everything would become mixed up and would not operate correctly. So, if there was a network that was incorrectly set up or installed, the computers on the network will not be able to communication with one another. Once the network has been fixed, all of the computers on the network will be able to transfer and communicate information back and forth.
UNIT 33: THE IMPACT OF COMMUNICATIONS TECHNOLOGY ON BUSINESS Describe how the internet operates 1. What is the internet? When and how did it start? The Internet, sometimes called simply "the Net," is a worldwide system of computer networks (a network of networks in which users at any one computer can, if they have permission they get information from any other computer (and sometimes talk directly to users at other computers). the 1960s and 1970s, the US Department of Defense funded programs where computer scientists were paid to develop Internet protocols.
The network layer then uses its protocol (IP) and translates that www.yahoo.com into an IP address. The network layer is also in charge for determining the best route through the network in order to get to the IP address destination. The data link layer is, unlike the other two which are virtual, a physical address with is permanently encoded to a device through its network card. The data link layer is a unique identifier to each computer in a network. Thus a MAC address is the only address that will always remain the same, transport and data layer address can change depending on the network.
Fill in the Blank The mos widely used IP addressing scheme is Ipv4. The most recent and largest address space IP addressing scheme is Ipv6. To distribute the IP addresses automatically, a network administrator would configure the DHCP service. The first attempt at breaking up IP address space used classful addressing to provide address ranges of differing sizes. Prior to the introduction of the domain name system, computers use hosts files to map human readable names to ip addresses.
If you connect to your internal network, what should you check if you cannot connect to web servers on the internet? C. Proxy settings 3. What technology automatically configures IRQs, DMA channels, I/O port addresses, and memory addresses ranges for an expansion card? D. Plug and Play 4. Which built-in account gives full access to the computer system?
Example: For the Marsh call center process, the client target is >5 minutes of an AHT, which an agent would have to maintain. Calculation The universal formula to calculate AHT – The average ACD {Automatic Call Distribution} talk time + Average Hold Time + ACW {After Call work}. Automatic Call Distributor (ACD). The specialized telephone system used in incoming call centers. It is a programmable device that automatically answers calls, queues calls, distributes calls to agents, plays delay announcements to callers and provides real-time and historical reports on these activities.
d. denial-of-service attack (an example: smurf attack) 4. What type of device guards against an attack in which a hacker modifies the IP source address in the packets he's issuing so that the transmission appears to belong to your network? b. proxy server 5. Which of the following devices can improve performance for certain applications, in addition to enhancing network security? b. proxy server 6.
