Computer processor speed helps determine how fast your system performs. We’ll help you answer: does the speed of your computer really matter?

We’ll be providing you with a guide, along with example scenarios for the different processor speeds available today. However, let’s first look at what processor speed is.

What is Processor Speed?

The speed of a processor is measured in hertz, which relates to how many cycles they run per second.  Nowadays processors are measured in Ghz (gigahertz), which means billions of cycles are processed per second.

Not all computers are designed to respond to tasks as quickly as you may be led to believe when a store sales rep tries to sell you a computer. Even with a decent processor, such as a quad core, one needs to be wary of dwarfed speeds that will limit how fast a processor carries out tasks.

It’s no use having a multi core processor that responds to tasks slowly, when one can purchase a cheaper quad core with higher speed capacity. For instance, a 2 Ghz quad core is slower than a 3 Ghz dual core.

Processor Speed Scenarios

Below 2.0 Ghz:

Processors with this speed will only manage to cope with basic email and web browsing activities. It’ll also be able to process light document writing. However any other types of demanding software, such as for graphic editing and video creation, will make it struggle and fall flat on its face. Here are some budget systems on Amazon.

2.0-3.0 Ghz:

This range of speed will cope well with web browsing, working with emails, running business programs such as patient management systems and general multi-tasking.  This category works well for the average office computer.

Above 3.0 Ghz:

If you need to run demanding graphic and video systems, then you’ll need to have a computer that comes with a processor of at least this speed. This range is also very good for heavy multi-tasking and creating multimedia such as high resolution graphics and videos.  This category also works well for running many programs, documents, and browser tabs at once.

Having considered all of the above scenarios, a higher speed processor will only work to its potential if it’s supported with enough computer memory. You’ll also need to consider purchasing at least a dual core processor to get speedier and decent PC performance.

WiFi vs Ethernet

Should a wired or wireless connection be used for peripherals? We’ll list the pros and cons of wired and wireless connections to help you decide.

Most peripheral devices, such as printers, scanners and cameras support Wi-Fi connections. While it’s easy to think that Wi-Fi can work in just about any place in the office or home, some considerations need to be noted beforehand to think this through carefully.

In this article we’re going to illustrate the pros and cons of having a device connected over Wi-Fi and over a wired Ethernet connection by comparing their connection speeds, integrity of connection, aesthetics and accessibility for both choices.

Connection speed

VirginMediaSpeedTest
Wireless speeds today are limited at 50-150 Mbps whereas wired ethernet connections can support speeds up to 1000 Mbps. If you’re looking for a speedy connection, a wired connection is your best bet.

Integrity of the connection

Wireless connectivity is subject to interference from other devices which can cause the connection to drop altogether. Even situating a wireless device near a kitchen that uses a microwave can cause interference with wireless connections.

Ethernet cables do not have many of these issues. A wired connection different is jacketed by the protective plastic tubing that envelops the naked wires. These wires assist to direct the connection through the cabling, helping it maintain integrity protecting the data which runs through it. This makes it less likely to lose connections and to be intercepted by wireless scanning tools which are rare but do exist. To get maximum speeds, a Category 5e or Category 6 cabling is highly recommended.

Aesthetics and accessibility

However with wireless, a device can be placed in just about any area that is also in close proximity to a power socket. This gives more options as to where a device can be based around the office. Limiting the amount of wires is also much more visually appealing and is one of the biggest benefits to choosing Wi-Fi.

If you’re still undecided, ask yourself the following questions:

For instance, for a wireless printer, how much use will it get and for how many users? Does it need to be situated in a place without access to an Ethernet socket? Are speed and data integrity more important than a slower network speed connection?

By drawing up the pros and cons of both wireless and Ethernet connections mentioned above, and matching it up the most important requirements, it’ll help you choose a wired or wireless connection

intelConfused as to which Intel processor to opt for? We’ll help explain the differences between the Intel Core i-series and give scenarios for their ideal use.

We have previously touched on processor cores and speeds, which will come in handy to have a rough understanding of as we discuss the differences between Intel’s Core-i processor series.  Intel has designed three different processor classes that are designed to cater for various purposes.

First, let’s understand the difference between the three processor classes.

i3 vs i5 vs i7

What may first sound a little misleading are the names of the processor types; the Core i3, Core i5 and Core i7.  It’s easy to think of these processors as having the number of cores reflected in their names i.e. Core i3 with 3 cores or three sets of cores. However in actual fact, the names of these processors do not represent the number of cores each processor carries.

When it comes to cores, the Core i3 is a dual core processor; the Core i5 and Core i7 are dual and quad core processors. Each one of these processors also differs by their cache size and their ability to multi thread.

Only the Core i5 and i7 both have Turbo Boost, which permits the processors to increase their clock speed when needed. This all depends on the availability of cores within the processor, processor temperature, estimated power consumption and current available power.

How multi-threading works as shown by Intel.

 

Therefore, the difference between a Core i5 and a Core i7 is mostly distinguished by hyperthreading. Hyperthreading is designed to allow each core in a processor serve more than one thread at a time. Therefore a core i7, with four cores, is able to run a total of 8 threads whereas a Core i5 and Core i7 have both the same threading capacity of 4.

However each Core-i series follows a progressive order with improved caching capabilities. Cache helps processors remember data to speed up data access requests. The Core i3 processors come with 3 MB cache, core i5 generally come with 6MB ( with the exception of the 661 model which only holds 4MB maximum cache), and the higher end Core i7 will comes with 8MB cache.

The general consensus regarding the Core-i series is the higher the series, the better its performance.

Now that we’ve outline the general differences between the three Core-i series of Intel processors, let’s outline a scenario for using each one.

Core-i processor class usage scenarios

Core i3 – this class of processor can be considered entry level, which is designed to cope with basic document work and to help carry out light browsing activities.

Core i5 -this type can be summed up as a mainstream processor that’ll perform well when multitasking with more memory intensive programs, such as with running accounting software, having many documents open and heavier web browsing activities such as having many browser tabs open.

Core i7 – this class of processor is considered high end, which will cost more but will give the best performance. For instance, it’s ideal for editing graphics and video with lots of multi-tasking.

3015019_Nano_Server_Microsoft_cloud

Leaked slides discuss Microsoft’s upcoming plans to provide a thin lightweight windows server known as Windows Nano Server. Here’s what we know so far.

A slide deck, which was leaked, shows Microsoft’s plans to enhance the ability of installing Windows on a “headless” machine.  A “headless” machine is a system which does not have a keyboard, mouse or display. This new type of server will be branded as the “Nano Server”.   This new “headless” design will allow administrators to access it via web-or-PowerShell-driven management tools.

The New Nano Server Features

nano_server_windows_server_210499357

..

  • The new Thin Light Weight Windows Server will look to replace the typical Windows server environments which are compliant with POSIX, particularly for company networks which use Windows systems.
  • Designed to be streamlined to fit within the Cloud infrastructure. The idea will be to split the server into two roles. One part will be a server within a container and the other part will devote itself to managing the cloud.
  • However it has one obvious part where it does not keep up with the competition: its dependency on still needing a client machine to act as a graphical user interface to access the server.
  • This implies that a graphics card, mouse and keyboard will in fact be required to access it. This will step back to the usual way that administration is normally carried out through the GUI.
  • The roles or work performed exist on the Nano Server’s exterior. In the image, it does not contain any metadata or binaries but instead depends on standalone packages. These are installed similar to applications.
  • It will support containers, Hyper-V, clustering, storage, ASP.NET, PaasV2 and V.Next.
  • It will be developed to support drivers, anti-malware, System Center and Apps Insight agents.
  • The slides imply that Windows Nano Server is going to be placed as the core of an environment which is clustered or virtualized.  It is also being declared as the only true-cloud-OS assuring provision of reduced resource expenditure and faster deployment than the current solutions from Microsoft.
  • Even if it will present support for next generation applications which are distributed, the slides show that it is going to be suitable for current applications running on Windows Server.
  • Expected to be the next step to support working within OS Apps and the Cloud Infrastructure- to Follow the server core pattern.
  • No specific fixed time frame is attached, only speculation of a possible release for some time in 2016.
  • Microsoft has not talked openly about this and dismisses it as “speculation and rumors”.

The-Humanity-of-Printing

Do you know what to do when your printer stops working? If not, we’ll help you take out some of the guesswork with some basic troubleshooting tips.

Printers may be an understated piece of equipment. It almost becomes part of the office furniture, until it gets used for printing.  But what happens when the office printer stops working, what is one to do before they decide to call for help?  Firstly, remain calm. The good news is that we’ve pieced together a checklist for what to do when a printer stops working.

What to check before first

Just a preliminary note: It may sound obvious; however, most printers can actually display the problem on their LCD displays or give clues as to what the problem is. Make a note of any errors which may flash on this display too.

  • Restart the printer. Simply power off and then switch it back on. Sometimes all that is needed for a printer to work well again is a simple restart. This often does the trick, almost works like magic!
  • Clear the printer’s sprint queue. This is a common problem where one print job within the print queue jams up all other print jobs waiting for their turn to print in the queue. To clear the queue, simply head over to the printer’s setting from your computer’s Control Panel on Windows 7 or 8 by going to

Start > Control Panel > Hardware and Sound> Printers
Double click the printer that has the problem.
A print queue should be available, and from there you can delete and clear the print jobs to tell it to stop printing. Click Cancel to remove the print jobs.

Try to send a new print job to test its working fine.

  • Make sure your printer has enough supplies. By this we mean enough paper to feed through it and plenty of ink to use. Insufficient levels of these can make a printer unhappy, so be sure to not overlook this!

Paper Jams- a common problem

paper-jam

Printers are usually good at telling their users when there’s a paper jam. If there is one, it’s a good idea to check that paper isn’t stuck. Even the smallest piece of paper jammed in the printer’s rollers qualifies as a paper jam.

Sometimes a printer will complain about a phantom paper jam. In this case, it’s a matter of checking there’s enough paper in the paper tray and all trays or doors are closed shut.

Servicing your printer

Laser jet printers need servicing from time to time, so it’s always a good idea to have it serviced. Once a certain amount of printing threshold has been reached, the printer may request a service to replace one of its components from wear and tear such as a print drum or paper roller, helping to further extend the printer’s life.

Check the warranty

It’s always a good idea to register your printer for its warranty as soon as it arrives in the office. You’ll want the least amount of trouble by having your warranty activated which will cover you for a faulty printer and have the problem fixed promptly by the vendor.
