Internet of Things (IoT).

Internet of Things (IoT).

Internet of Things (IoT)  refers to devices that collect and transfer or transmit data through the internet. It also describes the network of physical objects instilled with sensors, software, and other technologies. It’s for the purpose of connecting and exchanging data with other devices and systems over the internet.

We have IoT devices that connect wirelessly to a network and have the ability to transmit data. They are the nonstandard computing devices.

Internet of Things (IoT) makes our world to get connected together. Nowadays we almost have internet infrastructure wherever and we can use it whenever.

IoT

IoT security and privacy

With any technology, there’s the potential for good and bad. Here you would need to know what could go wrong at any given time.

Strong security is essential. Connection to the internet can open the door to cybercriminals. Cyberattacks already access data like bank logins, credit card numbers, and more.

The Internet of Things will continue to open up opportunities for new online threats. For instance always ensure that your connections stay safe and secure.

The best ways to help defend your networked devices is to make sure that your router is secure. Think of your Wi-Fi router as the front door to your online world

 

Example of an IoT devices.

The devices communicate with usable sensor data to users, businesses and other intended parties.

The devices can be into three main groups: consumer, enterprise and industrial.

  1. Consumer connected devices

This includes smart appliances, smart speakers, toys, wearables and smart TVs. In a smart home, for example, devices are designed to sense and respond to a person’s presence. They also tend to give you warnings in case of any and possible solutions.

  1. Enterprise IoT devices

They include, smart security, smart locks smart lighting and smart thermostats.

This are edge devices a business design use. Because they are geared towards maintaining a facility or improving operational efficiency. A good illustration would be in a boardroom meeting, where you get to have a PowerPoint presentation. This will need the lights dim and PowerPoint loads on the screen.

  1. Industrial IoT devices

The design of this devices are in use mostly in factories or other industrial environments. Here sensors used to monitor an assembly line or other manufacturing process.Ensuring that key processes are running optimally,data from various types of sensors should transmit it to monitoring applications.

Parental control guidelines on the Internet

Parental controls are the names for a group of settings that put you in control of what content your child can see. They are useful tools to help minimize the risks your children may face, but they are not 100% effective. Combined with privacy settings these can help you protect your children from the things they shouldn’t see or experience online. It’s really important to teach your child skills like critical thinking and resilience, so they know what do if they encounter risk. Always encourage them to talk to you about anything they find upsetting online.

 

Guidelines for Safe Internet Browsing by Age

Kids under 5 years:

Build a white list and choose a handful of sites you’re comfortable with, and plug them into the device your child uses. As he gets older and needs greater access, simply add to the list.

Kids 5 to 8 years:

Use a kid-friendly browser and disable the browser on your child’s device by going to Settings. Replace it with a kid-friendly one that you download from the app store. Choose an app which lets her access only sites it identifies as safe.

For 9 years and up:

Go with Google Safe Search, this search engine does an effective job of filtering explicit images and content. On a computer, go to the preferences section in Google, click “Turn on Safe-search” and then “Lock Safe-search.” On a mobile device, go to Google, click “Settings,” then select “Search settings” and choose “Filter explicit results.” Repeat for each browser.

INTERNET LATENCY

INTERNET LATENCY

Latency, also called ping. It measures how much time it takes for your computer, the internet, and everything in between, to respond to an action you take. Like clicking on a link. In other words, it affects how responsive your internet connection, video, or game feels.

Ping is another way of describing latency. The ping is the request you’re sending to the server, and the ping rate is how long it takes for that request to transmit and come back with the result.

It is generally measured in milliseconds (ms) and is unavoidable due to the way networks communicate with each other. It depends on several aspects of a network and can vary if any of them are changed.

Aspects of internet latency.

What causes latency?

  1. Transmission medium:The physical path between the start point and the end point. The type of medium can impact latency. Distance is usually the main cause of latency—in this case, it refers to the distance between your computer and the servers your computer is requesting information from.
  2. Propagation: In physics, propagation is the sending out or spreading of light or sound waves, movement. When we’re talking internet, propagation is the action of sending out your data packets to a server. Theoretically, latency of a packet going on a round trip across the world is 133ms. In actuality, such a round trip takes longer, though latency is decreased when direct connections through network backbone are achieved.
  3. Routers: The efficiency in which routers process incoming data has a direct impact on latency. Router to router hops can increase latency. An old, slow router can bog down your computer’s connection to your internet provider’s modem, whether you use WI-Fi or an Ethernet connection.
  4. Storage delays: Accessing stored data can increase latency as the storage network may take time to process and return information.
  1. Internet connection type: Your internet connection type can also play a role in how high or low your latency is. For the most part, DSL, cable, and fiber internet tend to have lower latency, while satellite internet tends to have higher latency.

 

How do you fix high latency?

  • Turn off any downloads, and be sure to check for anything that’s downloading in the background.
  • Close any unused applications or browser tabs.
  • Use an Ethernet cable to connect your device to your router or modem, if at all possible.
  • Update your router’s and modem’s firmware—outdated firmware can even cause slow internet speeds.
  • Make sure your router settings are solid. Dig in to your modem and router, and make sure none of your settings are creating bottlenecks. Most routers have a settings page where you can change your password, adjust which channel the router is using, and more.Usually the login information is printed right on a sticker on the bottom of the device.
  • Upgrade your internet package. If you’ve upgraded your equipment and tweaked your settings but still aren’t getting the speeds you want, the next step is to upgrade to a faster internet package. Not sure how much speed you need? We’ve got a handy speed recommendation on our packages, check them out.

 

Bandwidth vs. latency

Higher bandwidth is better. Bandwidth is a measure of how much data can be transferred from one point in a network to another within a specific amount of time. When talking about internet connections, it’s usually measuring how much data can be downloaded to your device from a server on the internet.Your actual bandwidth will often be less than your maximum bandwidth because of network congestion and other external factors. If you want to see how fast your internet connection is now, use a speed test.

 

Lower latency is better. It refers to how much time it takes for a signal to travel to its destination and back. To test this, your computer sends a “ping” of information to a remote server and measures how long it takes for the signal to come back.

Lower latency is better because it is essentially a delay between when you take an action and when you see the result—high latency is when it takes longer to see the results. The less delay, the better.

Every time you put in a request to your internet connection, it sends a signal to the server to retrieve the information and then bring it back to you. Since this usually happens pretty quickly, it is measured in milliseconds.

THE INTERNET AND ITS USAGE.

THE INTERNET.

The internet is the global system of interconnected computer networks that uses the internet protocol suite to communicate between networks and devices. The internet provides networking, as it links computers to allow them operate interactively. It is a network of networks that share each other. It is inter-working as it can connect to different networks using intermediary devices. On the internet every device has its own unique IP address. Principles of an IP address:

  • It identifies the host,specifically its network interface
  • It provides the location of the host in the network.

Principles of an IP address is characterized as follows:

  • A name indicates what we seek.
  • An address indicates where it is.
  • A route indicates how to get there.
  • The header of each IP packet contains the IP address of the sending host, and that of the destination host.

PEERING ON THE INTERNET.

Peering is a process by which two internet networks connect and exchange traffic. This allows direct hand of traffic between customers without having to pay a third party to carry that traffic across the Internet for them. This could involve running a circuit across town from one network’s facility to the other’s. Network operators may peer for reasons such as:

  • They have control over their traffic, in that it goes across the Internet via whatever path the transit provider decides to use.
  • It’s cheaper to hand off traffic themselves rather than paying somebody else to do it.
  • It gives greater control over their traffic flows, or allows them to better serve local populations.

 

PEERING

Peering is typically settlements free.

We have two main types of peering, public and private peering.

Public peering, done through an Internet exchange, is more common and more efficient. An Internet exchange is an Ethernet switch in a data center, which all the networks peering in the facility connect to. A network can peer with many other networks through a single connection using an Internet exchange. Peering arrangements needs to be negotiated with each peer, but no new cabling needs to be done.
Private peering within a data center combines the two approaches. Two networks put routers in the same building, and run a direct cable between them rather, than connecting through the exchange point switch. This is most useful when the networks are exchanging a large volume of traffic, which won’t fit on a shared connection to an exchange point. This is sometimes done when the networks are exchanging a large volume of traffic, which won’t fit on a shared connection to an exchange point.

Managed Service Provider

Managed Service Provider.

Managed Service Provider, also known as MSP. This is a service provided by IT companies to small and medium-sized business, and sometimes large organizations, governments and non-profits.

It is applicable in instances where by the businesses do not have full-time in-house IT staff members.

A MSP either charges on an annual basis or a monthly recurring fee. There is a service level agreement (SLA) that is tied to the contract. The contract is well detailed with a list of all items and tasks to be included.

Managed Service Provider

Tasks list might include as;

  • 24/7 network monitoring of servers,
  • desktop,
  • laptops
  • endpoint devices.

Depending on the terms and conditions spelled out in the contract the service provider may also include repairing any issues that arise, patching of devices to keep them updated and monitoring the system. www.kemnet.co.ke

Types of MSP Providers

  • Network Infrastructure
  • Software as a Service (SaaS)
  • Communication Services
  • IT Support
  • Security as a Service

MSP provides a great value for money by being proactive in fixing issues before they occur. MSP assists in optimizing the IT environment to prevent and lessen the need for regular break/fix issues. Mostly MSP provides remote services. A Remote Monitoring and Management system (RMM) monitors and fix issues remotely.

MSP has access to the environment and regularly monitors it and is better prepared for any emergency issues that may arise. It also has skilled technicians in Level 1, 2 and 3 that assist with the IT tasks and fix arising IT issues.

The MSP provides different billable rate for each technician assigned to work on any given issue.

Once you start working with a managed service provider, the remote team will take over on day-to-day monitoring and maintenance for your network, sometimes including jobs like antivirus protection.

Monitoring Your Network

IT service providers use remote monitoring and managing (RMM) software for networks and servers. RMM software enables the MSP company to easily manage your network and closely monitor it without sitting next to a server. If something goes wrong, or if a server on the network isn’t operating as it should, the RMM software notifies a system administrator. This software can also make it much easier to apply important updates, like security patches. It can even automate routine processes like finding more disk space for a server.
