What Is Cloud Computing?
Cloud computing is when entities share a network of remotely accessible servers. The servers are hosted on the Internet, allowing businesses to manage data "in the cloud†instead of on a local server. It’s a shared space in which devices in the network can access data from anywhere.
Although cloud computing has only picked up major traction in the last two decades or so, the idea has existed since the 1960s. The noted computer scientist John McCarthy introduced the concept when he envisioned technology that would allow computing to be sold as a utility like electricity or water. He suggested that each subscriber would only need to pay for the capacity they actually used and that some users could offer services to other users.

What is cloud computing and storage
While McCarthy’s vision looked like a pipe dream at the time, he was describing a phenomenon that’s taken the digital world by storm — Infrastructure as a service (IaaS). Specifically, he was describing the basis of cloud computing. Today, 77 percent of businesses have one or more applications or part of their infrastructure in the cloud. What is the purpose of cloud computing for businesses? To save money and increase efficiency.

Microsoft already had a relationship with CyberX
As with Intel and its May acquisition of Israeli mapping startup Moovit (which it acquired just weeks ago for $900 million), Microsoft already had a relationship with CyberX: most recently, the two announced a deal in March of this year to integrate Microsoft’s Azure cloud platform into the CyberX ecosystem, so that CyberX customers using Azure could continue to have those services covered by CyberX’s security systems, along with the rest of their on-premises network activity.
Unlike Intel’s strategic relationship, it appears that Microsoft was not among CyberX’s investors: the startup had raised just under $48 million from backers that included large VCs like Norwest Venture Partners, Qualcomm Ventures and Israeli VCs Glilot and OurCrowd, as well as individuals like Facebook’s Stan Chudnovsky and Gigi Levy-Weiss.

More generally, Microsoft’s been a prolific investor and acquirer in Israel, and recent cybersecurity-specific M&A have included purchasing Aorato, Adallom, Secure Islands and Hexadite.
On the enterprise front, it’s also been making acquisitions big and small, with the most recently before this being the acquisition of a small outfit in the US called ADRM that had built extensive data-modelling maps for different industries (some 75 in all), useful for helping businesses visualise how and where data moves and where tech or human investments might be necessary within an organization. It, too, is becoming a part of the Azure machine.

IT tribunal stays Rs 100 crore tax demand against Tata Education
The Income-Tax Appellate Tribunal (ITAT) on Thursday stayed a tax demand against Tata Education and Development Trust.
The Income-Tax department last year raised the Rs 100 crore tax demand owing to the annulment of registration on past exempted income. This was part of a bigger case involving cancellation of registration of six of Tata Trusts' entities with an estimated tax implication of Rs 10,000-12,000 crore.
Tata Education and Development Trusts is one of the entities of Tata Trusts, which is a majority stakeholder in the group's holding company Tata Sons.

While granting stay on Tata Education, ITAT said that the entity will have to file "an undertaking setting out investments of not less than Rs 99.75 crore which it will not encash till the application is disposed off."
However, the order by ITAT abstained from making any observations on legal implications of the new provision regarding the powers of the Tribunal to grant a stay.
The appellate tribunal has referred the matter to a larger bench to take a call on whether the amendment also limiting tribunal powers to grant stays is obligatory or just a directive and what type of assets should be produced by an assessee before the ITAT can grant them a stay.

What makes 5G different to 4G?
To effectively plan for 5G it is important to understand how the technology will be delivered, how it is different from current 4G networks and what the planned use cases are. 5G is not just limited to mobile; it is the underlying mechanism that will support a range of M2M applications being deployed and iterated over the next several years. When planning for 5G coverage, it is important to have a clear understanding of the technologies involved and time frame you are planning for.

Why 5G is the heart of Industry 4.0
We are in the middle of the fourth industrial revolution. While many business leaders are paying attention to energy consumption and automation, is 5G the true driver of Industry 4.0?
The first fundamental distinction is the frequencies over which 5G will be delivered: either < 6 GHz or mmWave (28+ GHz), both of which present their own set of challenges. The second distinction is the data transfer speeds involved. Current 4G networks typically have a fifty-millisecond delay whereas 5G is set to offer a delay of one-millisecond. Such small differences are unnoticeable to humans, but they will permit machines to achieve near-seamless communication.
5G mmWAVE operates in the 28 GHz and 39 GHz spectra and is able to deliver extremely high data rates to end users, using sophisticated network equipment. There is a downside however, because the higher the frequency, the smaller the coverage range and the less effectively the radio waves can penetrate objects, people, vehicles, buildings, natural obstacles such as terrain, all of which impede signal transmission.

Crazy-useful PC productivity apps
For all the popularity of mobile apps and cloud services, the venerable PC continues to be a mainstay of computing today. Indeed, the versatile desktop interface means that the bulk of a day’s work continues to be done on PCs for most users.
We've found some pretty cool productivity apps that will substantially improve your Windows desktop experience.

1. TidyTabs
If you ever got frustrated tabbing through multiple application windows, then you need to install TidyTabs from Nurgo Software. The lightweight utility lets you organize the desktop by stacking multiple windows together in a tabbed arrangement, even for unrelated applications. This opens the door to grouping applications based on projects worked on, decluttering the desktop and generally keeping things tidy.
Aside from the ease of stacking windows of disparate sizes together, the tool also works particularly well for segregating browser tabs. Brower windows containing their own tabs can be stacked together without messing up their sequence, and can even be renamed to highlight for improved management. The utility is priced at $9 per license, though a limited freeware version is also available.
2. AquaSnap
AquaSnap adds a bunch of capabilities that Microsoft should probably have built into Windows 10 from the start, offering a variety of window-handling tricks to make the desktop a much more enjoyable experience. For instance, window snapping makes it a breeze to align windows side by side as they dock together like magnets.
And rather than having to individually resize a group of several tiled windows, simply hold down on the "Ctrl†key to either resize them simultaneously, or move multiple adjacent windows as a group. Other features include the ability to set a window to stay right on the top — with the ability to set it to varying levels of transparency. AquaSnap is also made by Nurgo Software, but it costs more at $18. A freeware version is available for personal use, and may suffice if you only have one monitor.

The Right Ethernet Cable for the Right Network
An efficient Ethernet cable management plan, especially in high-density and challenging network environments, increases the versatility of network maintenance and operation. It also contributes to the system’s uptime and lowers operation cost, which makes your life a whole lot easier! The demand for high-density networks can be attributed to the following:
Know more about the Workstation PC.
The need for energy efficiency through minimized cable impact on the flow of air
Merging of servers, storage, and virtualization
The results are more cables per rack and highly used cable racks. This could result in operators being confused by the many cables, which causes increased human errors.
How to choose the right cables for a high-density network center
With increasing technology and virtualization, Ethernet networks are advancing and becoming more complicated as organizations strive for higher levels of reliability and performance. Choosing the right cabling solution will help you attain reliable performance. The following guidelines will help you choose the right cabling solution:
The environment you will be using your cables in
The environment you will be using your cables in will ultimately affect how long they last. If they will be used in a control room, you might not need really flexible cables as the vibration is minimal. However, if they will be exposed to chemicals, oils, and vibrations such as those in factories, you will need highly flexible cables.

What is ITIL?
In the 1980s, IT Service Management best practices emerged as most organizations were migrating or planning to migrate to digital technology. The term ITIL was later introduced to refer to these best practices.
Know more @ IT job responsibilities
Definition of ITIL:
IT Infrastructure Library (ITIL) refers to a group of documents that provide a framework and best practices for building an IT Service Management (ITSM) solution. Organizations supporting an IT infrastructure can increase efficiency while reducing service management costs if they follow recommended ITIL processes.
In addition to best practices, ITIL provides common terminology, such as "Incident,†"Problem,†"Change,†"Configuration Item (CI),â€â€Knowledge,†and "Configuration Management Database (CMDB),†all of which are examples of terms used by those who support IT.
Education that focuses on ITIL best practices is available for people who wish to gain a better understanding of ITIL. Furthermore, ITIL certifications can be valuable to have on a resume and are offered in a variety of areas.

Local Area Network (LAN)
If more than one computer is to be connected to a network, this usually takes the form of a Local Area Network (LAN). Networks like these can include two computers in a private household or several thousand devices in a company. Networks in public institutionsm such as those used by public authorities, schools, or universities, are also implemented as LANs. A widely-used standard for wired Local Area Networks is Ethernet. Networking technologies such as ARCNET, FDDI, and Token Ring are less common and widely outdated. Data transmission is either electronically based on copper cables or via fiber optic cables.
Read more: what is a LAN cable
If more than two computers are to be connected in one LAN, additional network components such as hubs, bridges, and switches are needed, which act as coupling elements and distribution nodes. The network type LAN was developed to enable fast transmission of large amounts of data. Depending on the structure of the network and the transmission medium used, a data throughput of 10 to 1,000 Mbit/s is normal. LANs enable convenient information exchange between the various devices connected to the network. In a business context, it’s common to share files, network printers, and applications via LAN with several computers.
If a local network is implemented via radio, it is referred to as a Wireless Local Area Network (WLAN). The WLAN standard’s technical basis is defined by the IEEE 802.11 family of standards. Wireless local networks offer the ability to easily integrate devices into home or corporate networks, and are compatible with wired Ethernet LANs. However, the data throughput is lower than for an Ethernet connection.

How is a Network Operations Center Different From a Help Desk?
An IT help desk is generally an in-house team of IT support technicians that troubleshoot end-user issues. Technicians respond directly to the user to resolve technical problems as they arise, and hence, are mostly reactive.
Unlike NOCs, help desks do not proactively monitor client networks for potential issues. Some NOC services providers do include the help desk function as part of their offerings. However, many MSPs prefer to retain the help desk function rather than off-load this to the NOC services team because they prefer to keep control of the customer-facing functions.
Read more: find your NOC
NOC technicians also check performances of CPU and how networks are performing. NOC technicians may have to put in flexible hours when the need arises.
Technicians deploy, maintain, and resolve IP switching, remote access protocols, routing, and firewalls. It is the specialists’ job to maintain reports on usage of bandwidth, utilization of the server, uptime, and other crucial elements.
