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.
Stacie Rollins Monday , December 15, 2014 Nt 2640 Unit 1 Assignment 1 Network IDs used to be divided into classes, which were Class A, B, and C. These classes were allowed to have a range of addresses. This class-based system would work well for a while, but the rapid growth of the Internet it becomes evident that this addressing scheme had to be changed in order to support the many networks that were being created. A class full system would be created and still used the IP addressing fundament of a classless system. This 32-bit IP addressing system is subdivided into two portions; the network address space are the host address space. Class A addresses were created for a very large network with few logical network segments and many hosts that have the high-order bit set to zero.
Describe at least three different networks (computer or data communications) which you access or interact with on an average day. Binary data codes like EBCDIC, ASCII, or Unicode are often presented using hexadecimal notation rather than a long list of 0’s and 1’s. Likewise other items requiring long sequences of 0’s and 1’s like IP addresses to identify network location are generally presented in non-binary formats as well. Describe the relationship between a hexadecimal character and its associated binary. Describe the relationship between one octet of an IP address and its associated binary.
There are many things that college students use computers for. One of the real reasons that almost every college student has a computer in their dorm or in their house is to type up all of those papers that are assigned to them by their professors. Another one of the biggest things in technology is the Internet. You would swear that now someone would die if they didn’t have the Internet. People use the Internet almost every day to either check e-mail, search something from the Internet, or they can even use it for AOL instant messenger.
breaking long messages into several smaller messages The primary reason for networking standards is to: ensure that hardware and software produced by different vendors can work together ___________ refers to the spreading of the signal that different parts of the signal arrive at different times at the destination. dispersion ______________ refers to the time it takes for a signal to travel from sender to recipient (highly exaggerated with satellite transmission). Propagation delay A coding scheme that uses 10 bits to represent each character is capable of representing _________ different characters. 1024 Which type of digital signaling would experience fewer errors because it has more distinct signals? bipolar When sending four bits at a time using frequency modulation, the number of different frequency levels that would be needed would be _______.
Miller referred to each of these items as chunks. Miller further suggested that the capacity of the short term memory may be enlarged by grouping items together by associations/links they have with each other. However Cowan 2001 concluded that STM is likely to be limited to about 4 chunks. This shows that it may not have been as extensive at miller thought. The encoding in STM means the way that information is changed so that it can be stored in memory: Baddeley (1966) aim was to explore the effects of acoustic & semantic encoding in STM.
I not only use my tablet to do research on the internet but also to take notes, write papers and create presentations among other things that will prove useful even till I move on to college. Organizers and task managers also keep me organized and a time table application makes sure I follow my study table accordingly. With hundreds of applications being developed specifically for learning, studying has never been this exciting and productive. The iPad can be used to connect people and I use this to my advantage. Whenever I have problems with schoolwork and any other things, I can get different views and opinions from people around the world, giving myself a broader understanding and exposure to the matter concerned by posting the problems I face online.
Also I’m always on my phone either texting, or tweeting. While the internet does take up most of my time, it doesn’t mean it’s a bad thing. The internet allows me to discover new things each and every day. Back in the day, if I wanted to get information about something I would have to spend hours reading books, now with the internet I can find facts in seconds. For example my older sister lives in Europe and Facebook makes it easy for me to talk to her in just a click of a button.
Throughout my day for almost everyday, I am constantly on my cell phone when I am able to go on it. The reason for this is so I can check my emails whenever and wherever I am when I am not home. It is convenient to have a cell phone in handy when away from home, because it makes it easier to contact someone. Almost everyone has a cell phone, and almost everyone use it to socialize with friends and family. Also, I logged on the computer on Thursday 5:15 PM to work on my educational planning assignments as I needed to navigate the Bakersfield College website.
Ban Hand Held Cell Phones While Driving Cell phones in the last five years have become a portable computer, GPS, and our main source of communication to reach out to people. Text messaging in society has become a daily routine in daily lives as well. The portability of today’s wireless phone means consumers are no longer constrained by location. Stay in touch with family and friends, or other important transactions. Kill two birds with one stone: get everything you need done anywhere except while driving.
