Applications Running Slowly on PC
When applications slow down or hang, this may be due to a number of causes. But the most common is processing power and memory.
Computer memory - or random access memory - is used to temporarily store data during program execution. In fact, the more memory you have, the more programs you can run simultaneously.
RAM does not necessarily speed up a computer, but it can improve the operation of applications and programs. So, yes, it's usually associated with performance and speed.

Slowing down the computer resulting in poor execution of applications is extremely common. However, this is not an easy solution, as many factors could contribute to the slowdown.
For example, your computer may need more RAM or random access memory to better manage processes.
A computer can also slow down if the hard disk is full - often the primary hard disk on which the operating system is installed and running. But a failed or end-of-life hard drive can also cause a significant slowdown.
Then there is the number of applications and processes running. Google Chrome, for example, is known to consume a lot of system memory and resources because it keeps many processes open.
First, you must identify the cause of the slowdown. The best way to do this is to duplicate the problem by closing everything, opening applications and processes one by one.
Open the Windows Task Manager by holding CTRL + ALT + Delete and choosing the corresponding option. The task manager window will appear. Make sure you look at the "process" tab. Here you can see all the applications running on your computer.
Start closing the applications you started - or even some that started automatically - but do not close any tasks that require heavy use of the system. You will know immediately if something needs a lot of system, because an error window will appear asking if you really want to close this process. Of course, when that happens, you will want to abstain.
Once you are confident, not all user applications are running. Open your applications and tools one by one and check for a slowdown. This will allow you to find the culprit.

Arista's Big Switch buy adds customers, engineers, network software
Arista Networks has acquired data center networking company Big Switch Networks. Arista bought the company for its 300 customers, engineering team and software for managing switching fabrics.
Arista announced the acquisition this week, along with its earnings results. The company reported that revenues fell 7.2% year-over-year in the fourth quarter ended Dec. 31. The drop was due to reduced spending by cloud and communication service providers, which are the company's most lucrative customer segments.
From a product perspective, Arista was particularly interested in Big Switch's Big Monitoring Fabric (BMF) and its Big Cloud Fabric (BCF), Arista CEO Jayshree Ullal said in a conference call with Wall Street investors. BMF is a network packet broker for BCF, which is software for managing physical switches as a single fabric. Switch makers that support BCF include Accton Technology, Quanta, Hewlett Packard Enterprise and Dell EMC.
Arista expects BMF to be a "perfect complement" to Data Analyzer (DANZ), the network packet broker within the company’s EOS network operating system. BMF will bring more extensive packet-based analysis to DANZ, Ullal said.
"BMF is just icing on the cake," she said. Arista planned to continue supporting BMF and BCF as separate products.
Arista plans to offer BCF as a management tool for converged infrastructure. The latter is a data center architecture that packages compute, networking, servers, storage and virtualization tools in a prequalified turnkey appliance. Ullal expects partner Dell to use BCF within its infrastructure bundles.
Big Switch's 300 customers included 100 that were also Arista customers, Ullal said. Arista hired 75 Big Switch employees, the majority of whom were engineers.

Cybersecurity is a board level issue
Misconceptions and knowledge gaps increase this distance between security and oversight. How can boards dive deeper into the world of security and overcome the entry barriers to collaboration? Seeking advice, I reached out to prominent security leaders: Joel Fulton, the former CISO of Splunk; Jeff Trudeau, the CSO of Credit Karma; and Yassir Abousselham, the former CSO of Okta and the newly appointed CISO of Splunk. Here are their tips for board members.
Recognize security as both a business risk and an opportunity
First and foremost, it is imperative for the board to appreciate the impact that information security can have on the business. Boards should treat security as a top business risk as well as a top business opportunity. Major security events can have a significant impact on revenue, brand, and even lead to catastrophic results.
Abousselham elaborates: "In an era where organizations are handling large amounts of sensitive information and governments are actively pushing more stringent privacy laws, data breaches have serious ramifications for the organization, its customers, and partners.â€
Know more about the Cyber Security Consultant career path.
Bridge the technical gaps
Contrary to popular belief, security leaders believe that domain expertise is not a prerequisite to making smart security decisions. Instead of focusing on every technical bit and byte, Trudeau suggests the conversation should concentrate on understanding the risks and ensuring they are properly addressed.
Yet, even on a macro level, security concepts might be difficult to fully understand, so a short and dedicated security training for the board can come in handy. It’s also key to remember that it’s not only the board members who may feel like fish out of water. The CISO, too, can get intimidated and might over-rely on the comfort and familiarity of technical details.

Career Path Options For IT
There is no one true path to working in cyber security. People come at it from all angles – math, computer science, even history or philosophy. Yet all of them share a deep and abiding interest in how technology works. Security gurus say this is critical. You need to know exactly what you’re protecting and the reason things are insecure.
Train In General IT
To that end, many experts suggest that you begin with a job, internship or apprenticeship in IT. This will verse you in fundamentals such as administering & configuring systems, networks, database management and coding. You’ll also get a sense of IT procedures and real-world business operations.
Focus Your Interests
Because it’s impossible to be an expert in all categories, employers also suggest you focus on an area (e.g. networking security) and do it well. Think ahead 5-10 years to your "ultimate security career†then look for starter IT jobs that will supply you with the right skills. Sample career paths could include:
Exchange administrator → Email security
Network administrator → Network security, forensics, etc.
System administrator → Security administrator, forensics, etc.
Web developer → Web security, security software developer, etc.

Cloud ERP security - what are the advantages?
Companies are increasingly relying on cloud hosting for ERP and other enterprise software. While companies are often attracted to the cloud by lower costs and convenience, the cloud also offers significant advantages in cybersecurity protection when compared to traditional corporate network and hybrid solutions. Cloud ERP security benefits include network management by specialized personnel, automated patching, enhanced monitoring, access controls, protection from large scale attacks, and the latest encryption standards.
A recent security experiment emphasized why local corporate networks are so hard to protect. In a research study by Google and two universities, 300 USB drives were distributed around a college campus. Many of these USB drives were picked up within minutes and nearly half were plugged into a computer, thereby providing an opening for potential malicious software stored on the USB drive. If IT employees were impacted instead of college students, each USB drive could be a hacking weapon striking directly into the heart of a corporate security system.
The Cisco Certified Network Professional Security (CCNP Security) personnel should protect the data crossing a public or shared infrastructure.
