i3 vs i5 vs i7 – Wouldn’t it be nice if we had a way to easily decide which processor was right for us? First off what do all of these numbers mean?

Codename = SandyBridge

Sandybridge is Intel’s newest architecture/offering that was released in January 2011. This is still the fastest and most efficient architecture to date. It comes in three offerings, or flavors so to speak: the i3, i5, i7. Let’s begin by shedding some light on what these numbers mean, and what these processors have in common with one another.

i3-XXXX, i5-XXXX, i7-XXXX is the first way to tell if the processor you are looking at is truly the new SandyBridge architecture as they just switched to a 4 model number. Now, each of these offerings may also have a (K), (T), (S), (M).

The K stands for an unlocked multiplier. What this allows the user to do is to increase the multiplier on the cpu core without having to increase the fsb in order to achieve a higher clock speed. This is referred to as overclocking your processor. It is not warranted by Intel and should only be used by the most hardcore of PC users and builders as it can cause premature failure of the i3, i5, and i7.

The S and T stand for low-power and Ultra-Low-Power. While the M stands for mobile, which I am sure you already guessed. The mobile version is of course used in laptops only.

With speed comes power consumption unfortunately.

The two fastest processors are the i5-2500 and i7-2600 with the only difference being more l3 cache on the 2600 and the addition of Hyper-Threading.

These processors do use the 95W power design which is slightly higher power consumption than the other offerings. For the average user the Hyper-Threading will not make much of a difference to justify the price jump from the i5 to the i7.

However, if you are a student who is studying video/photography in school or a father who loves capturing his family on camera then the i7 is for you. The i7 allows for much better video and photo editing/encoding due to the Hyper-Threading technology.

I am sure you are asking yourself now, “What is Hyper-Threading? I see it mentioned over and over again when it comes to the i3 vs i5 vs i7 discussion but, am still a little confused as to the meaning behind it”.

Well, Hyper-Threading is a term coined by Intel to describe its technology which improves upon the ability to perform multiple tasks with ease.

The way it works is for every physical core the application creates, a virtual core is also created. This in turn allows the application to share the work load between both the physical core and the virtual core. This essentially transforms a dual core (2 cores) into a quad core (4 cores) or a quad core (4 cores) into an 8 core. This may sound awesome, but remember not all applications have the ability to use hyperthreading.

The most common instance of this is PC Gaming. The majority of video games on the PC do not support hyperthreading which is why most pc gamers save some money by going with the i5-2500k (no Hyper-Threading) vs the i7-2600k (Hyper-Threading).

For a gamer the i7 does not justify the $100 price markup however, for the video editor the Hyper-Threading significantly increases performance by up to 30% in some cases making it a worth while investment.

If you have a computer you are not unfamiliar to computer repairs. It is inevitable that your computer will eventually run slow or not at all especially if you are a novice to technology which lets admit most of us are. One of the biggest reasons clients bring their computers in is that they are slower than when they first purchased them. They always want to know who or what is to blame for this. No one wants to hear it but the problem your computer may be running slower than when you purchase it is… YOU!

Maintenance is the key in making sure your computer keeps running at peak performance. Just like your car needs regular oil changes and filter changes your computer needs tune ups to clean up the registry of old programs not in use, updates on spyware and adjustment of settings to insure peak performance. Of course there could be more reasons for the slow down. It is best to take the computer in to a local computer repair firm, as you would your car to a mechanic; to have it thoroughly looked at.

Other reasons that your computer may be having issues running slower than normal could be that your computer has contracted a virus. Trojans, spyware and malware may be the cause of the issue with your computer running slowly. Spyware creates an issue where outsiders have gotten into your computer without you knowing it and start sending out personal data to entities that will take advantage of your system and cause it to run slowly. Even if you have up to date virus protection you can still become infected it just lessens the likelihood. Computer repair in the form of a virus scan and removal are needed and can be done at your local computer repair store. It is also recommended that a tune up be performed on your PC at this time to regain the speed and efficiency of your computer.

You can also inspect your computer and delete files and programs that have been added that are unnecessary. The more files and programs you keep stored on the hard drive of your computer the slower it will run. I recommend having a separate flash drive to store big files such as pictures, word and excel documents. The space adds up quickly. Also, delete any unnecessary short cuts on your desk top they could be causing your computer to run at a snail’s pace.

It is important if you have tried all of the similar solutions to look at the computer’s hard drive. Run a disk defragmenter which will help optimize how data is stored and then Scandisk to help ensure nothing is actually corrupt within the drive.

Another issue that is common is that the processor is overheating. This is common. You will want to first make sure the cooling system in the computer, the fan, is running. If not it will need to be shut off and taken in for the fan to be replaced. If the fan is running look to make sure a build-up of dust is not causing an issue or that the cabinet the computer is stored in is not blocking the air flow. I have found this happens to me when I am in bed using the laptop and forget about the heat issue. If I set the computer on the blankets the air flow is blocked and the computer will have issues.

Memory, hard drive disk space and conflict in hardware/software are all problems that could also be responsible for the slowing down of your computer. If you have a computer repair check all of the above and there is still issues they will most likely recommend you do an OS reload. Basically this will consist of wiping the computer clean and reloading your operating system. Make sure your data is backed up before doing this. Also, this requires installation of the programs that you run on your computer. This is basically a last resort but it will make your computer like when you first brought it home.

Many activities happen in most places in a city. Different exchanges of activities transpire everyday in business establishments, schools, hospitals, streets, offices, and homes among others. Most often than not, these activities are often delayed or impeded with various crimes. These crimes include burglary, traffic violations, or even murder. Thus, the normal flow of activities is interrupted as crimes get in the way.

This is one of the most common reasons why many people are opting to install a surveillance camera system in their homes, businesses, offices, and other places where they conduct their everyday activities. Police departments likewise use security surveillance cameras to spot crimes such as over-speeding, robbery, and other threats to security. Security cameras systems are considered non-lethal tools that can stop criminals from doing their thing.

Setting up a surveillance camera system allows passive observation of the things happening around your area. Most often than not, surveillance cameras include infrared detectors, motion detectors, and ultra-sensitive microphones. Some people choose to connect their security cameras or surveillance cameras to a nerve network center of a police station so that response can easily be rendered in case a crime happens in their areas.

For a larger scope of surveillance, some people set up CCTV camera systems or security camera systems in strategic places within their vicinity. Operators of these security systems are able to call for help as soon as they observe a crime. Thus, police officers are able to arrive as quickly as they can to respond to the scene of the crime. Security camera systems are all capable of recording images and sounds, which makes them useful as evidence for proving a crime or convicting criminals.

When choosing to set up surveillance or security systems, you should consider several important identifiers. You should remember that criminals usually attack when the situation is perfect for their plans. However, if they are aware of the cameras in their target area, they tend to leave for fear of being caught in the video for evidence. Thus, you should set up your surveillance cameras in places where they are visible to people.

For most business establishments, announcing the presence of their CCTV systems works as criminals or lawbreakers are stopped from doing their unlawful acts. Criminals or lawbreakers do not want to get caught or taped in videos while doing their stuff. In fact, the crime rates for areas that announce the presence of their CCTV systems are much lower as compared to those that hide their surveillance systems.

As much as possible, it is preferable to install or set up surveillance systems near the vicinity of policemen. This is to quicken the response rates of police officers as well as apprehend criminals as quickly as possible. If the operators of the surveillance systems are trained enough, they will also be able to determine the number of police officers needed to respond to the crime. The operators can also guide the policemen on how they can act upon the crime.

Why do we need a Data Center? Before finding out the use and the purposes of these centers we need to know what exactly a Data Center is. This center can be termed as a place or a location that is utilized to store several electronic and communication equipments. It stores critical computer systems and associated components for several companies and organizations. These centers usually keep high standards for assuring their functionality. These standards include climate control, backup power, fire prevention, physical security and network infrastructure. These centers have all modern security features, to stop access of users who are not permitted see and use the data stored in it. The centers have continuous power supplies to make sure constant operations are maintained, even at the times of power failure. A usual center has routers and servers kept on wall mounted data racks and it stores information through its own server machines. These work on a continuous basis, therefore the quality of the server machines and its safety is important for its users.

The purpose of a Data Centers is to allow storing huge amounts of equipments connected to communications, computers and electronics. The main purposes of taking services from these centers are to make the data safe and secure. The measures adopted by these centers protect the data from various environmental hazards as well as several other technical problems. These Data Centers are usually maintained by the web host for handling the data needed for its operation, which includes the web servers that stores website and emails. Big organizations generally set up their own centers, while small and medium businesses use a co-location facility. A co-location facility can be defined as a facility in which servers and other related equipments held by several organizations split space with each other.

A Dedicated Server is a computer on the web that a hosting provider solely offers to an individual. They have their own processor, hard drives, Random Access Memory (RAM) and bandwidth capacity. As these servers are exclusively used by a single user, it enables them to install and run any program on it. These servers provide users with high speeds, added bandwidth and permits them to organize and supervise the server. These are generally used by companies as these fulfill the needs of large organizations. Dedicated Servers also allow other parties, who have the access to use the server, to connect to the hosting server and use the same program at the similar time.

Backing up data and being able to recover it in an acceptable time frame are both crucial to planning your backup infrastructure.

Factors affecting a backup solution -

• DATA
• BACKUP SOFTWARE
• BACKUP SERVER
• INFRASTRUCTURE
• BACKUP TARGET
• BACKUP MEDIUMS

Do you want to be able to do a full backup, incremental or differential?

Backup is not really about backup, it is about restore! Backing data up is an insurance policy!

Understand the backup window and restore performance that you might need.

From autoloader to tape library’s, VTL (Virtual tape library’s) and beyond! There are many different options and lots of vendors, as is common these days where business IT is concerned.

There are many ways to skin a cat springs to mind!

There are uncertainties in the market where the term Autoloader and Library is actually concerned, and you should know that the Autoloader is being phased out and being changed for a more scalable device which starts with fewer drives but has room to add more.

If you are suffering from a lack of capacity, a lack of performance or both, or inadequate restore performance it is time to think about a new solution to provide a continuation of your “insurance policy”.

There are lots of different players where backup solutions are concerned:-

Software to consider:

• SYMANTEC
• QUEST

Hardware To Consider:

• QUANTUM – Tape solutions, D2D, Encryption, advanced management and software suite.
• OVERLAND – NAS, Tape solutions.
• NETAPP – Multi protocol, Wealth of functionality – de-duplication, application aware snapshotting, replication, thin provisioning to name only a few!
• DELL EQUALLOGIC – Stable and popular appliance for SMB which is an iSCSI RAID system with replication and thin provisioning.
• DOTHILL – Kings of R & D, high capacity and high performance RAID systems with a great story to tell.

A backup solution can be expensive but it is quite simple to work out exactly what specification will suit your needs by understanding what your recovery point objective is and what your recovery time objective is.

RTO – How long is acceptable for the recovery of a backup.

RPO – How old can the data be before the recovery time objective is no longer achievable.

Usually having a graph to show how quickly you need to restore data of certain ages is a great way of finding out what hardware you will need.
