Quality of Service
(QoS)

22
Q

commonly used for connecting devices like headphones, keyboards, mice, and smartphones to other devices or accessories.
1) has a range of up to 30 feet.
2) speeds are relatively low compared to Wi-Fi, suitable for short-range data and audio transmission.
3) operates in the 2.4 GHz
band.

A

Bluetooth

23
Q

is used to provide internet connectivity in
areas with limited terrestrial infrastructure, including remote regions and maritime environments.

A

(IP)

29
Q

is a simple and cheap networking device that works under the physical layer of the OSI model and connects a bunch of computers in a Local Area Network(LAN).

A

HUB

30
Q

by definition, ties together different networks both inside and beyond
the physical space of an office network. In most cases for SMBs, this means tying your network to the Internet, the greatest network of them all. A router is “smarter” that a switch. It prioritizes the flow of information from the Internet to your networked devices, and protects your devices from cyber threats.

A

Router

31
Q

is any piece of equipment that allows networked devices to communicate and share information. On an Ethernet network, you’re connecting desktop PCs,printers, servers, network attached storage (NAS), voice over IP (VoIP), surveillance systems—any device with an Ethernet cable port. Switches tie together these devices into a network.

A

Switch

32
Q

Worldwide coverage, across the state, across the country or even across the world. Across 4000 miles.

A

Wide Area Network (WAN)

33
Q

Connects components within a limited distance. Generally up to about a hundred meters or 300 feet. Most common in small office or one floor of an office building.

Ethernet: 802.3
Wireless: 802.11

A

Local Area Network (LAN)

34
Q

Connects scattered locations across a city or metro area. Up to about 25 miles.

For example: We have a university with different campuses all those different
campuses are connected the same network like the DMV, Police Department,
libraries, administrative offices they’re all connected together to form one
network

A

Metropolitain Area Network (MAN)

35
Q

is a circuit-switched WAN protocol that uses digital signals to transmit voice
and data over traditional telephone lines.

was used for video conferencing, early internet access, and remote office
connectivity but has declined in popularity with the rise of broadband.

A

(Integrated Services Digital Network) ▪ISDN

36
Q

Load balancers distribute network traffic evenly across multiple servers or connections, optimizing performance and
preventing overloads.

A

Load Balancer

37
Q

is a data link layer protocol used for establishing a direct connection between two nodes, typically over serial connections like phone lines or dedicated leased lines.

A

Point-to-Point Protocol (PPP)

38
Q

is a packet-switching WAN protocol that operates at the data link layer. It uses virtual circuits to connect remote networks.

A

Frame Relay

39
Q

is a communication system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations. When we’re talking about the microwave frequency range, we’re talking about frequencies in the range of 300 megahertz to 300 gigahertz

A

Microwave link

40
Q

Basic Internet
▪ Speed: This tier offers basic internet access with relatively low download and
upload speeds, usually ranging from 1 to 10 megabits per second (Mbps).
▪ Usage: It’s suitable for light internet usage, such as web browsing, email, and
basic social media.
▪ Price: Tier 1 plans are typically the most affordable.

A

Tier 1

41
Q

Standard Internet
▪ Speed: Standard internet plans offer faster speeds compared to Tier 1, often
ranging from 10 to 100 Mbps.
▪ Usage: They are suitable for moderate internet usage, including streaming videos
in standard definition (SD), online gaming, and regular web surfing.
▪ Price: Tier 2 plans are priced higher than basic tiers but are still relatively
affordable.

A

Tier 2

42
Q

: High-Speed Internet
▪ Speed: High-speed internet plans provide significantly faster download and
upload speeds, typically ranging from 100 to 1000 Mbps (1 gigabit per second, or
Gbps).
▪ Usage: These plans are ideal for demanding activities, such as streaming in high
definition (HD), 4K video streaming, online gaming with minimal lag, and
supporting multiple devices simultaneously.
▪ Price: Tier 3 plans are priced higher than the previous tiers due to the increased
speed capabilities

A

Tier 3
