Question 1

What is an IP Telephone?

Accepted Answer

An IP telephone system uses packet-switched Voice over IP(VoIP) or Internet telephony, to transmit telephone calls over the Internet, as opposed to the circuit-swithed telephony used by the tradtional Public Switched Telephone Network (PSTN). IP telephone systems typically comprise of a VoIP private branch exchange (an IP PBX) and desktop VoIP phones (IP Phones) that connect to a service provider, via a Local Area Network (LAN).

Question 2

Do I need a phone system for my business?

Accepted Answer

All businesses can benefit from some sort of phone system that can present themselves in a professional manner.Clients are able to reach you on a business line that is often by an automated attendant is an excellent way to achieve that. IP phones provide the features and tools that small businesses find most vaulable, such as voicemail to email, call forwarding, call screening, music on hold and online faxing.

Question 3

What is WiFi?

Accepted Answer

WiFi is a technology that allows electronic devices to connect to a wireless LAN (WLAN), using either 2.4 or 5 GHz radio frequencies. A WLAN should be secure, and password protected. If left open, it would allow any device within its range to access the resources of the WLAN network.

Question 4

Should I upgrade to Wi-Fi 6 ?

Accepted Answer

Wi-Fi 6 is the latest and greatest new wireless networking standard. 
 
● Greater data transfer speed. 
The theoretical speed of WiFi 6 is 10Gbps. It achieves this speed increase by combining the 2.4GHz and 5GHz spectrum bands and employing multi-user, multiple-input, multiple-output technology for both uplink and downlink data transfers.
More efficient data encoding leads to the higher throughput. More powerful chips used to encode and decode signals allow more data to be carried by the same radio waves. A single device can achieve up to 40% faster data transfer when using WiFi 6 versus WiFi 5. Even 2.4GHz networks will experience increased speeds when using a WiFi 6 router.
 
● Increased battery life
Wi-Fi 6 lets devices and routers schedule communications with a feature called Target Wake Time, make any connected device more power efficient. This will conserve power, as it means the Wi-Fi radio spend more time in sleep mode. And that means longer battery life.

Question 5

What is the difference between a managed or unmanaged switch?

Accepted Answer

Unmanaged Switches 
● To provide Ethernet devices with network connections so they can communicate with one another. 
● Not allowed for configuration or require set up, unable to control network traffic. 
● Simply plug and play. 
● Suited more with small networks, to edge services or add temporary groups of devices to a larger network. 
● Less expensive than managed switches.
 
Managed Switches 
● Offers additional feature that unmanaged switches cannot. 
● Able to manage, configure, monitor and troubleshoot issue with networks. 
● Each switch has its own IP address for identification and addressing. 
● Able to create traffic controls, prioritize channels based on the importance of data, investigate performance problems, remotely deploy fixes and even create new virtual networks for segmentation purposes. 
● Provide a layer of security that can monitor unauthorized access and encrypt communication. 
● Feature built-in redundancy so data is duplicated and can be recovered if a device or network fails.
●In terms of applications, managed switches are most often deployed as part of the industrial network backbone to monitor and control traffic. They’re also used to connect mission-critical devices to networks.

Question 6

What is CAT6 cable?

Accepted Answer

CAT6 cables, also called Category 6, provide lower crosstalk, a higher signal-to-noise-ratio, and are suitable for 10GBASE-T (10-Gigabit Ethernet) up to 55m or 1GBASE-T up to 100m. As a means of future-proofing your network, CAT6 is generally a better choice and worth the small premium in price. CAT5e and CAT6 cables are both backwards compatible, which means newer CAT6 cables can be used with older CAT5e, CAT5 and even CAT3 equipment.

Question 7

What is PoE?

Accepted Answer

Power over Ethernet (PoE) capabilities let you direct power out of the switch and into another device. This allows you to put network endpoints in areas that aren't easily accessible or are far away from other power sources. You can use this to setup wireless access points, IP Surveillance systems, and VoIP phone networks across the office.

Question 8

What is the difference between router, hub and switch?"

Accepted Answer

Router is mainly used to route network traffic from one network to another network. Router is actually a small computer that can be programmed to handle and route the network traffic. It usually connects at least two networks together, such as two WANs or a LAN 
 
Hub is commonly used to connect segments of a LAN (Local Area Network). A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. Hub acts as a common connection point for devices in a network. 
 
Switch A switch is able to handle the data and knows the specific addresses to send the message. It can decide which computer is the message intended for and send the message directly to the right computer. The efficiency of a switch has been greatly improved, thus providing a faster network speed.
