Question 1: what does the term internet mean?

Answer:

a 'network of networks'. The Internet is literally a collection of interconnected private and public networks

Question 2: What is quality of service (QoS)

Answer:

becomes a primary mechanism for managing congestion and ensuring reliable delivery of content to all users.the router can manage the flow of data and voice traffic, giving priority to voice communications if the network experiences congestion.Question 3: Different types of network media have different features and benefits. Not all network media have the same characteristics, nor are they all appropriate for the same purpose.what are the criteria for choosing network media

Answer:

what is the maximum distance that the media can successfully carry a signal?, into what type of environment will the media be installed?, what is the amount of data and the speed at which it must be transmitted?, what is the cost of the media and installation?

Question 4: what are data center used for

Answer:

is a facility used to house computer systems and associated components.

Question 5: what internet connection options are commonly used by SOHO's

Answer:

cables, DSL, cellular, satellite, dial-up telephone.

Question 6: Explain in detail how a packet-Switched connection works.

Answer:

splits traffic into packets that are routed over a shared network. A single message, such as an email or a video stream, is broken into multiple message blocks, called packets. Each packet has the necessary addressing information of the source and destination of the message. The routers within the network switch the packets based on the condition of the network at that moment. This means that all the packets in a single message could take very different paths to the destination.

Question 7: what is redundancy?

Answer:

Having multiple paths to a destination

Question 8: Wide Area Network (WAN)

Answer:

A network infrastructure that provides access to other networks over a wide geographical area, which is typically owned and managed by a telecommunications service provider.

Question 9: what are the disadvantages of peer-to-peer networking?

Answer:

no centralized administration, not as secured, not scalable, all devices may act as both clients and servers which can slow performance.

Question 10: Intermediary devices

Answer:

Provides connectivity and ensures data flows across the network.

Question 11: Another wireless solution for the home and small businesses is wireless broadband, explain

Answer:

This uses the same cellular technology used to access the Internet with a smart phone or tablet. An antenna is installed outside the house providing either wireless or wired connectivity for devices in the home.

Question 12: Metropolitan Area Network (MAN)

Answer:

A network infrastructure that spans a physical area larger than a LAN but smaller than a WAN (e.g., a city). MANs are typically operated by a single entity such as a large organization.Question 13: at minimum, home or small office network security should include what options?

Answer:

Antivirus and antispyware - These are used to protect end devices from becoming infected with malicious software.Firewall filtering - This is used to block unauthorized access to the network. This may include a host-based firewall system that is implemented to prevent unauthorized access to the end device, or a basic filtering service on the home router to prevent unauthorized access from the outside world into the network.Question 14: Specific features of LANs include:

Answer:

LANs interconnect end devices in a limited area such as a home, school, office building, or campus.A LAN is usually administered by a single organization or individual. The administrative control that governs the security and access control policies are enforced on the network level.LANs provide high speed bandwidth to internal end devices and intermediary devices.Question 15: in order to achieve the goals of network security, there are three primary requirements

Answer:

-Confidentiality - Data confidentiality means that only the intended and authorized recipients can access and read data.-Integrity - Data integrity means having the assurance that the information has not been altered in transmission, from origin to destination.-Availability - Data availability means having the assurance of timely and reliable access to data services for authorized users.

Question 16: Cloud computing

Answer:

allows us to store personal files, even backup our entire hard disk drive on servers over the Internet.Applications such as word processing and photo editing can be accessed using the Cloud.

Question 17: Explain bring your own device

Answer:

is about end users having the freedom to use personal tools to access information and communicate across a business or campus network.

Question 18: Wireless LAN (WLAN)

Answer:

Similar to a LAN but wirelessly interconnects users and end points in a small geographical area.

Question 19: List and explain the two types of topology diagram.

Answer:

physical topology diagrams - Identify the physical location of intermediary devices and cable installation.Logical topology diagrams - Identify devices, ports, and addressing scheme.Question 20: Processes running on the intermediary network devices perform what function?

Answer:

regenerate and re-transmit data signal, maintain information about what pathways exist through the network and internetwork, notify other devices of errors and communication failures, direct data along alternate pathways when there is a link failure, classify and direct messages according to priorities, permit or deny the flow of data, base in security setting.

Question 21: what is the purpose of a SOHO or small office/ Home office

Answer:

often set up by individuals that work from a home or a remote office and need to connect to a corporate network or other centralized resources. Additionally, many self-employed entrepreneurs use home office and small office networks to advertise and sell products, order supplies and communicate with customers.

Question 22: Local Area Network (LAN)

Answer:

A network infrastructure that provides access to users and end devices in a small geographical area, which is typically an enterprise, home, or small business network owned and managed by an individual or IT department.
