Difference Between Analog Signals And A Digital Signal

1)A network is when two or more computers are connected together and are able to share data and communication.

Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also

2. What is the difference between a WAN and a LAN? Which type of network is the Internet? Which type of network is the classroom network?

A LAN is a ‘Local Area Network’. It is a small network of computers most often

A Wide Area Network ( WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect

How would you define a network? What is bandwidth? What is a NIC? List three types of media used for network connections.

Failures are important to know about that way if they do happen you know the steps to take to resolve and fix them in a timely manner. The more you know about failures, the less likely they are to cause severe problems to your computer or network. It is also important to know that

16. Witch of the following statements is true comparing LANs and WANs? LANs generally connect devices that are nearer to each other, compared to WANs. WANs are purchased, and LANs are leased.

You are working as an IT consultant for the Senior Management team of a large comprehensive school. The management team has asked for information regarding different types of networks as they are considering upgrading all of the IT systems within the school. You

Availability keeps data and resources available for authorized use, especially during emergencies or disasters. This policy will address common challenges to availability. Denial of Service this is due to intentional attacks or because of undiscovered flaws in implementation. The policy will address loss of information system capabilities because of natural disasters. The policy will also focus on equipment failures during normal use.

Then what happens, soon after, when network issues arise that require significant attention and investment? You may find yourself facing a complete outage or suboptimal performance due to components failing. You may face large, unanticipated bills to replace equipment at the most inopportune times of your

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

Local Area Network or LAN for short is the term used for computer networks located at a single location such as a small business located at a singular location. They are generally used for businesses, organisations and the likes to transfer data amongst their systems as opposed to transferring data to outside of their location. A LAN typically will rely on wired connections due to the benefits of increased security and speed, but a network called a WLAN exists, which is a Wireless Local Area Network and this may prove useful for those who come to work using mobile devices such as laptops, phones, etc. WLANs are simply local area networks that consist solely of wireless connections using a wireless access point (WAP) as the central hub. However, LANs can be a mix of both wireless and wired.Typically in a LAN, systems connected to the network are able to share resources among each other, send data to servers and use peripherals such as printers, scanners &

4. Which TWO (2) of the four network types (e.g., LAN, WAN, Wireless LAN and MAN) might

A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.
