Network Quizzes Online & Trivia

Networks allow people to send messages and keep data accurate from one computer to another. It allows many users to have access to their data and manipulate it if needed and others can look at it. They do not need to be on the same computers to do this. However, a physical network address is needed too. This is a way of identifying the host of the network. At one point, telephone numbers were used as the network address when people used dial-up for their internet. Now, people use wifi. A MAC address is known as a media access control address. It is different because it allows people who want to use wifi to be able to use it with a router.

The first virus detected was called 'Creeper' and was found on ARPANET which was the predecessor to the internet. The virus was written by Bob Thomas in 1971. It was used to infect DEC PDP-10 computers that ran the TENEX operating system. Elk Cloner was written by a 15-year old and was designed to infect Apple II computers in 1982. Elk Cloner ended up being responsible for the first large-scale computer virus outbreak. Macro is not the name of a virus but a type. Macro viruses are written in the same language as certain programs like Microsoft Word or Excel and install software on your computer when certain functions are selected.

The correct answer to this question is the Internet. The Internet is a part of our everyday lives. Whether for work, school, or to browse through Instagram, we all need the Internet. The first website was by Berners-Lee in 1991. This website was to teach users how to create theirs on websites. Though the Internet is more used today, the concept has been around since the 1900s. Thinkers like Vannevar Bush and Paul Otlet knew that electrons could be used to communicate wirelessly. They did not have the technology available to make it happen. Another thinker and inventor, Tesla, is quoted as predicting smartphones.

The data link layer or layer 2 is the second layer of the seven-layer OSI model of computer networking. This layer is a protocol layer that moves data between adjacent network nodes in an area network or between nodes on the corresponding LAN segment. The functional data link layer supplies the substantive and procedural means to transfer data between network entities and might furnish the means to detect and correct errors that may occur in the physical layer. At the data link layer, either a span or a layer two switch can be installed to a segment. Hubs and repeaters at the physical layer only serve to extend a network.

Dexter0907 Step 1Input ACLs configured on the inbound interface are checked. Step 2Unicast RPF checks to see if the packet has arrived on the best return path to the source, which it does by doing a reverse lookup in the FIB table. Step 3CEF table (FIB) lookup is carried out for packet forwarding. Step 4Output ACLs are checked on the outbound interface. Step 5The packet is forwarded.

In peer-to-peer networks, no single computer has more authority than another, by default.

The main difference between the two is that UMTS is known to be a type of cellular technology while the WCDMA is known to be a type of air interface. The WCDMA is normally used in order to communicate with other devices. UMTS means Universal Mobile Telecommunications System. This is the newer and more modern version of the GSM networks that used to be rampant a few decades ago. Some may assume that they are the same but the WCDMA is normally used to make sure that the signal will become more efficient and that the signal will be passed on properly to the different mobile network operators. This will ensure that people can communicate properly.

PPO stands for the preferred-provider organization while POS means Point of Service. It can be confusing for a lot of people to choose which one is better, especially if they are not aware of the differences between the two. POS is very similar to the HMO, but this is not as restrictive. With PPO, you will be allowed to visit the healthcare provider that you want without the need to get a referral from a physician. This will lower the costs that you have to pay for. PPS is different because it focuses more on how you can build your wealth as an individual so that you will have more money in the future. Their main goals are different from each other.

LAN is known to be one of the things that people need if they want to connect to the internet. The LAN will allow different devices to be connected to the internet properly. There are times when only a few computers will be connected by the LAN and there are also instances when there are so many gadgets that would need to be connected. This will depend on how strong the LAN is. The VLAN is often used by those who would like to limit the gadgets that will be connected to the network. For example, businesses would like only their employees to connect. It will make use of VLAN instead of LAN so that it can limit people from connecting.

LPR and RAW are both network protocols, used in network printing. The term network printing refers to printing to one printer from multiple computers and devices, without the need for cables. This is done by connecting the printer and computers to the same network. LPR stands for Line Printer Remote. This protocol allows computers and printers to work together in a network, by using LPD, which is line printer daemon, and TCP/IP connection (transmission control protocol/Internet protocol). The RAW protocol is a computer programming language. It allows documents to be translated before they are sent to the printer. The printer interprets the RAW protocol and translates it before it prints.

There are half dozen differences between single stage and multistage multiplexing but the most common one is that Single stage multiplexing means that HO ODU’s can be mapped only to the same type of OTUk, but multi-stage multiplexing allows that one HO ODUj is still mapped to another HO ODUk before mapping it to OTU. Single stage multiplexing also helps in bandwidth fragmentation and improving the wavelength channel utilization whereas multistage doesn't do that.  

The correct answer to this question is False. Distributed systems help users share. Components of distributed systems are located on various network computers. This system communicates and coordinates their actions with each other through messages. The purpose of these messages is to achieve a goal that they have in common. Being that they are sharing, there is no need for the user to log on to a machine, explicitly know what the machine can do, explicitly submit data to the correct location, and explicitly tell the machine how to return their results, because this information is already shared.
