Help Desk vs Service Desk

Help Desks are a subset of Service Desks – however, there are subtle differences of focus with the two. Service Desks aim to manage higher level, strategic IT processes and is also referred to as Managed IT services or similar, whereas IT Help Desks are usually found in a separate service on its own dedicated to serve specific common issues for end users.

Help Desks refer to providing solutions to issues usually experienced by end users which can differ according to your business. This is usually done through a ticketing system involving the end-user being guided through problem shooting methods and solutions via the Help Desk on their various issues. Some examples of Help Desk services would be responding to calls and customer requests as quickly as possible and recorded through an online ticketing system.

On the other hand, Service Desks are referred to strategic level processes and are the main point of contact for companies aligning the technology used in the business with the company’s goals and processes.

IT Service Desks (included in our Managed IT Services) aims to ensure the overall IT processes and infrastructure are working at its best to serve the company or business goals it’s been created to achieve. IT Service Desks encompass processes such as improving asset management, enhancing operations, allowing better communication between business departments and more.


What Does a Linux-Administrator Do?

A Linux-administrator wears a lot of hats, and the smaller your environment, the more hats you have. Linux management includes backups, file recovery, disaster recovery, new system releases, hardware maintenance, automation, user maintenance, home file-systems, application configuration and conformation, system security and storage management. System management is involved in almost every aspect of managing the hardware and software of physical and virtual systems.Strangely, you also need a large knowledge base of network settings, virtualization, interoperability, and even Windows operating systems. The Linux system-administrator must have technical knowledge of all aspects of network security, firewalls, databases, and the work network.

 

However, the reason is that, above all, Linux-Admin, you are part of a larger support team that often has to work together to solve complex problems. Security, in one form or another, is at the heart of the problems that the support team faces. The user may not have the correct access or approach too much. Daemons may not have the correct permissions to write the log file. No firewall exceptions were saved while performing the network configuration. There are hundreds of failures online, and it is your job to help you find and correct them.Linux management also needs to follow best practices, learn new software, maintain patches, read and follow security announcements, and apply hardware updates. On the other hand, Linux certification pathand training day is very full of perks. In fact, it never ends, but you have to choose the time to stop the commercialism.

Missing DLL Files on Computer

Another standard system problem - again, with Windows operating systems - is a DLL error. This means that a DLL file is missing or corrupt. Files that end in ".DLL" are dynamic link library files.

They holded many codes and instructions for programs. They exist to tell the operating system how to handle certain applications. Several programs can also open them simultaneously, which improves memory conversion.

A DLL file is essentially a unique feature that developers can include in their applications. These files contain instructions for the computer and the operating system (operating system). If one of these files is missing, it can cause a lot of problems, especially since there are many.

What does a PC Repair Technician do?

The best way to manage missing DLL files is to use the System File Checker, an integrated Windows utility. It will scan the system files on your computer"s main hard drive and make sure something is missing or corrupted. It is quite possible that files exist, but they may become corrupt over time. This can even happen if a hard drive starts to fail.

The System File Checker will scan all the necessary directories and replace or repair the files if necessary.

You can also use your Windows installation CD or installation ISO to manually copy the necessary DLL files, but this is much more complicated.

From a product perspective Ullal noted that the Big Switch monitoring fabric is a complementary solution to Arita"s DANZ (Data ANalyZer) software. In her view, the Big Switch technology is the "icing on the cake" providing deeper visibility, service nodes, recorder nodes and monitoring fabric capabilities. The Big Cloud Fabric is also expected by Ullal to be an important product, especially with Arista"s converged infrastructure partners like Dell Technologies.
