How To Fix And Repair A Slow Computer

How To Fix And Repair A Slow ComputerHow To Fix & Repair A Slow Computer!

Is your computer running slow? Mine did. And now i’m going to help to fix yours! In this article, i’m going to discuss what causes your computer to run slow and how you can get your computer running back like it was brand new!

We use computers everyday. Wether it be browsing the internet, talking to friends on Facebook, online purchasing. In this modern age, we depend on computers wether you’d like to admit it or not. We like our computers to be responsive and get the things that we want done quickly and effeciantly! The amount of times I wanted to throw my computer out the window because it ran slow is crazy! So I needed to find what was the problem and how I can sort it out.

There are many things to slow down a computer.

Spyware & Adware:

Spyware and Adware both play a part in slowing down computers. These ‘programs’ attempt to obtain informstion from your computer. Such as what tasks you may carry out, what websites you visit, your bank details and so on. Some can be harmless. Some can be destructive, fatal or just damn right annoying!

Viruses:

Viruses are similar (if not the same) as Spyware and Adware. A virus is a ‘program’ that copies itself and invades your files. These basicaly read/write your files in the background without you knowing. Which in turn, slows your computer down and leaving you wondering why.

A Large Registry:

The Registry in a Microsoft Windows operating system is a group of files that store configuration data relevent to all your programs and settings stores on your computer. Having a large registry dramticaly increases the load up time of your computer and day to day runnings of your system. The registry does not clean itself, it stores data for programs you may have deleted months ago!

General Clutter:

Did you now, when you delete things, they still remain on your computer until it is overwritten? Things like temporary internet files, internet cookies, a hard drive that is nearing its capacity all slow down your computer.

 

How to Safely Erase Your Hard Drive

Safely Erase Your Hard DriveData in a computer may become a security threat to the company. It is important to ensure data in the drives is safe by securely erasing the hard drives. Perhaps you have discovered a new PC with a better and bigger hard drive or a new PC with a better and faster SSD. No doubt, it is time to consider getting rid of your old PC. However, before tossing away your old PC in the trash bin, it is advisable to clean off the data and eliminate chances of identity theft. However, you must understand deleting data off the drive does not actually delete it entirely. This effort only goes to hide the data from immediate view. Therefore, to guard against identity theft and completely erase data from the storage device, it is advisable to take measures that are more drastic by using hard drive data erasers. Following these steps can completely wipe data from your system:

1.Backup data

It can take a few minutes to a few hours to erase data on a drive. Before initiating the process of erasing your disk, it is important to backup any data you may want to keep. This is because once the data on the drive is erased completely, it will be impossible to retrieve it from the drive. Remember multiple drives sometimes exist on a hard drive.

2.Download a data destruction program

There are several ways often used to erase hard drives. However, most of the data destruction software offers an easy way of erasing data in storage devices, while allowing the device to be used again. If you like, you can download any suitable free data destruction program. Furthermore, consider burning the ISO file in a disc or undertake any other steps required to install software or get programs on bootable disc.

3.Erase according to program’s instructions

Finally, consider wiping the drive based on the program’s instructions. Most of the data destruction programs use multiple techniques to wipe data from the drive. Therefore, you may consider checking out the effectiveness of every method utilized to complete the wipe. Once you have cleaned up a drive, you can rest assured all the data on the hard drive is gone for good. Therefore, you can now do whatever you need to do; perhaps install a new operating system on the drive, create new partition, give or sell the storage device or computer, dispose of or recycle it.

What Is an HBA

Host Bus AdapterHost Bus Adapter (HBA) is a tricky issue to cover. I don’t think there is a proper source that explains exactly what the function of an HBA is. From my understanding, the definition of this component arose from different sources combining knowledge into one bowl that eventually gave a sort of definition that some might understand and some won’t understand at all.

Well, I am here to make sense of it all for you and to prepare this one article that will summarize the HBA functionality.

HBA is a component that, as the name implies, connects to the Bus (these days the PCIe) in the host. A host is usually defined as the activator of the procedure, in our case it usually means a server.

The job description of this component is to connect the host to an external piece of hardware, usually a SAN (Storage Area Network), through a switch or any other type of storage out there.

There are a few different types of connections. RJ-45, which is what most know as Ethernet connectivity in 1GbE and 10GbE, is reserved to the NIC and server/network adapters (I will explain those in the future). This leaves the HBA with Fibre Channel and SFP (Small Form-Factor Pluggable) connectivity. There are other connectors such as SCSI but this is obsolete and I wouldn’t want you to bother with it. Let’s focus on what matters these days.

So why is the HBA important? Well, back in the day, like with everything else, the CPU used to be in charge of the data transfer between the hardware devices and it took the CPUs time and effort away from focusing on what really matters – calculations.

With the HBA around, the CPU can focus on its task and the HBA can be In charge of the data transfer and connectivity between the devices.

Let’s get back to the connectivity for now. The most popular connectivity that is associated with the HBA is Fibre Channel. It comes in 4Gb/s, 8Gb/s and the recent and blazing fast 16Gb/s. Fibre Channel is currently the most preferable connectivity for devices but the cost of implementation has led the industry to steer away from Fibre Channel to FCoE (Fibre Channel over Ethernet). SFP converged Network Adapters can accept the FC (Fibre Channel) protocol and the SFP protocol, which also lowers the cost since it’s an Ethernet protocol.

However, the fastest connectivity out there is without doubt IB (Infiniband). With up to 56Gb/s data transfer rate, no one can compete with it. However, due to the lack of competition in this industry IB pricing by Mellanox is pretty steep, even compared to Fibre Channel. This technology is the fastest without any doubt, but also a bit isolated from the mainstream, pushing Fibre Channel back to the spotlight.

To conclude, the HBA is an integral component of almost any infrastructure solution that does not involve Ethernet connectivity. Usually designed for higher speeds that Ethernet cannot supply (10GbE+), not many businesses will implement such an expensive solution. To those who are thinking of moving to FC, IB or FCoE I hope that now you have a better understanding of the necessary components to connect the dots.

5 Facts About Ethernet Adapters

Ethernet AdaptersIf you are like most modern humans, you likely use some form of Ethernet adapter on a daily basis. However, you may have little understanding of what an Ethernet adapter is, or how they work. This article will make all clear. Here are five little-known facts about Ethernet converters.

1. You are probably using one right now: As you may know, the most basic example of an adapter is what you use to connect to the Internet if you have a wireless network. In your computer, or possibly, attached to your computer, you have a wireless adapter that converts the wireless signal to the Ethernet signal that your computer operates on.

2. Adapters require a driver to operate: Typically when you use your computer to connect to the Internet, your operating system will automatically install a driver that is compatible with your systems. If this process is not automatic, you may have to go to the manufacturer’s website to download the driver manually. Once the driver is installed and connected to an open port you will be fully connected to your network.

3. There are adapters for computers without an Ethernet port: When wireless networking was first being established, many people owned computers that did not support wireless networking. In order to connect wirelessly, you were required to by wireless cards that connected to their computers to receive and convert the signal from the router. Today, those adapters have come a long way in terms of sophistication and performance.

4. They are not just used to connect to the Internet: Advanced Ethernet adapters are used in a plethora of different applications where there is a need to connect two different types of media. Adapters are used to automate systems and communicate vast amounts of data and information quickly and accurately. Ethernet converters are used in nearly every industry from oil and gas, to medical, to military.

5. They vary based on application, performance, and operating conditions: Adapters can be simple, like the one you use to connect to the Internet, or they can be built for performance and rugged conditions. On the high-end, fiber optic cables are paired and twisted, to provide the highest speed and highest fidelity connection. This type of adapter is what you would commonly find in new Metropolitan Area Networks that are popping up in some cities to allow high speed internet access to all citizens and visitors.

Hopefully after reading this article your eyes have been opened to the complexity and variety of Ethernet cable adapters. They serve a myriad of purposes to help businesses and people transmit data and information in a secure, high-fidelity manner.

Explaining File Server

File ServerA File server is a server attached to the LAN or any other network type. Its primary purpose is providing a shared file access such as documents, images or other files that can be accessed by everybody.

This type of server is designed based on the popular client-server scheme like explained in the Database server nugget.

This type of server is not intended to perform any computing tasks nor execute programs on behalf of the clients. It is simply a type of shared lower level storage device.

The file server can be accessed via a number of different methods. It can be through the FTP (File Transfer Protocol), HTTP (Hypertext Transfer Protocol but is different from a web server that provides dynamic among a static content), SMB (Server Message Block) /CIFC (Common Internal File System – which is usually for UNIX but is also supported by Windows) or NFS (Network File System – mainly UNIX). This might be a bit confusing as the database server or shared storage might be considered to be a file server as well but the difference is the security and connectivity. The database server will require record locking (security feature) and will be much more powerful as it will contain a huge database that is constantly processing as it pushes queries from and to the users connected to it. Usually the shared storage uses different connectivity; while the file server will probably will not require anything faster than the common 1GbE RJ-45 connectivity, the shared storage is usually equipped with 10GbE RJ-45, 10GbE SFP or 8GbE – 16GbE Fibre Channel and therefore much more expensive as well.

As mentioned above, the file server is used to store documents and files that are shared between all the devices connected to the same network, where the security doesn’t have to be top notch and the fastest connectivity is not required. Anything more than whatever the server is designed for would be simply an over-kill – something we are always trying to avoid in the IT infrastructure.

An enterprise level type of file server would be the NAS (Network Attached Storage). This is a file level data storage connected to a host and provides data access to the client(s). The difference between a NAS and a standard file server is that the NAS was built and designed to be a file server while a generic server is just a multipurpose server that was assigned that role. The NAS systems are networked (they have a management port that allows an IP address to be assigned and join them to a running network) storage devices that contain hard drives set up in a RAID for redundancy and data protection and they are using network file sharing protocols such as NFS, SMB/CIFS or AFP.

Since the NAS is a storage device and not a multipurpose server, this prevents from unauthorized personnel accessing it directly (it has to go through a host that the NAS is directly attached to) and downloading information, thus preventing any internet access directly to the NAS. This is the main security benefactor of such a device. The cost of this compared to a generic file server is priced accordingly, of course.

But the main question is – do I need a File Server? Preferably yes. Back in the day, NAS or file servers used to be very expensive, pushing a lot of smaller businesses to just storing all the info on their desktop computer and accessing it from all the workstations. This wasn’t such a good idea as you store a lot of critical files that are kept on someone’s desktop or workstation. This “someone” could also be surfing the web and getting infected with email worms and viruses. Instead you can lock the files with the server in the server room and prevent any access to it, isolating it from the commotion of daily operations.

But before you jump on this type of server, you need to ask yourself few questions? Do you need redundancy in that data? Some need it, some do not need it. Next, ask yourself, how much storage do I need? Usually File server systems are equipped with more drive bays, supporting larger capacities, even after configuring a RAID. Do you plan on expanding? And eventually, how much are you willing to spend on the unit? More redundancy and performance increase the price.

In conclusion, a file server has proven to be a very effective addition to any infrastructure. Unlike other servers roles I reviewed, this server is not a MUST in every infrastructure and you can get away with using other money-savings means to share your files and consolidate storage but eventually, when the business grows, performance becomes important and redundancy matters, there is no avoiding this and you should look into different NAS systems as possible options.

I hope you have a better understanding of what a File Server is, what a NAS is and whether you need one in your infrastructure or not.
