c. All Ethernet user devices can be up to 100 meters away (but no farther), while WLAN devices must typically be closer than 100 meters. d. The Ethernet distances must be decreased to match the maximum distance supported by the wireless LAN. Answer: C. Ethernet UTP standards all support a 100-meter maximum cable length. The 802.11 wireless LAN standards have a coverage area that is typically less than 100 meters. The literal distance depends on conditions in each wireless LAN.
Single-Mode Fiber uses a very narrow glass core and can transmit data at very high speeds or long distances. Multi-Mode Fiber uses a thicker glass core than single-mode fiber. As I have discussed each cabling solution has its own advantages and disadvantages. Copper cabling is best
Carry it over to the right. 32 is less than 63 so you will subtract and put a 1 for that value, and continue down the line. 2. Explain why the values 102 and 00102 are the same. Because when you plug the binary numbers into the 8 bit conversion table, the two zeros before the 10 equal nothing.
IP Address Class A, Class B, and Class C IP Address classes were the original organizational structure for IP addresses. The specific address class would determine the maximum potential size for a computer network. The address class would define which of the specific bits of the address would be used to identify the network and network identification, the bits to identify the host computer and host ID, and total number of host subnets permitted per network. Five total classes of IP addresses were defined, class A through E. Although the IP class term will commonly be used to describe the difference between one network and another, the practical use of addressing is not commonly used any more. It has been replaced with classless addressing where a netmask can be assigned to any IP address range.
The addition of a parity bit provides a means for error checking and so improve error detection. 2. As the parity bit is chosen to make the total number of 1’s in the 8 bit word an odd count, it forces a transition in the serial stream such that there can never be a long stream of 0’s or 1’s longer than 7. For example if we take the case of the number 3 which in ASCII is 0110011 and when converted to ENRZ becomes 0000000 and with the parity bit becomes 00000001. The disadvantages of ENRZ is 1.
Easy to share information over the internet. Easy to install Cost affective to operate Disadvantages of Peer-to-peer system: Machine needs to backed up individually The information is not centralized. You are allows to send resource one at a time P2p system will get slow if several users trying to send/share recourses at the same time. Only 10 or less people are allows to be on p2p system P2p system may not work as well as it would work when there is less than 10 people, meaning the less people in p2p are then the better. More computers cannot be added to the system if there is already 10 users.
they use an ip address instead of analog signals. Most people would instantly assume it is voice communications but in fact it is data communications mainly because it sends voice fragments over the internet via TCP/IP, hence the name voice over IP. Skype / Facetime: Skype and Facetime have allowed us to not only speak but also see people over the internet. These amazing things use both voice communications and data communications much like voIP does. Data sends these voice and video fragments over the
These are available to anyone and provide different service plans ranging from 10gb/month to unlimited usage. They provide wireless and wired connections and the speeds vary depending on your location. There are many different web hosting service some of them are paid such as fast hosts and some are free such as google sites. This will let put your web site online and also help you create them with custom templates for the less experienced user. Google Sites for example will only has 100MB of storage for free users this will therefore limit you of what you can have on your website, there are also very few templates what you can use so your site will not be unique to you or your business.
As cement usually represent only 10-15 % of a concrete mix (PCA, 2014), energy required to produce concrete isn’t so important. Actually, cement production energy is around 5 GJ/t, but reinforced concrete one is only 2.5 GJ/t (Penttala, 1997). In comparison, steel requires 30 GJ/t, and aluminium 270 GJ/t (Penttala, 1997). But, life-cycle doesn’t take in consideration only the production energy. It should consider energy consumption on all the life duration of the material.
The UK has a total birth rate of 13 per 1000 and the USA has a total birth rate of 14 per 1000. The low birth rates in both countries is mainly impacted by the fact that in MEDC’s, there is better access to good
