A program (software) designed to advertise products and/or services via software. These ad’s range from new cars to gambling sites. Advertising via adware, embedded into ‘free’ software, funds the development of this ‘free’ software. Most commercial based adware is a subtle small ad within the software. Others, generally illegal, have none desirable adware that can include pornographic content popping up every time you turn on your computer.
Also See related terms Anti Virus, Firewall, Malware, Rogue Anti Virus, Safe Surfing, Spam, Spambots, Spyware, Trojan Horse and Virus.


Anti Virus
Software to prevent the infection of Viruses and other related malicious software. There are many different manufacturers, and versions, of Anti Virus software. Anti Virus software needs to be kept up to date, so that it is aware of the latest infections. These updates are generally done automatically over the internet, but may require a subscription normally by an annual licence.
It is important to check if your Anti Virus software is up to date and not to let your subscription expire. Pro Logic Computers (UK) Ltd recommends - AVG Internet Security for full comprehensive protection.

You can never have too many copies of your data!
We recommend you save your documents onto your computer and also make a copy on-to a memory stick (or other type of external device). This way if either device fails you have a backup!
Do not save ONLY to a memory stick (or other type of external device). Some people save important data ONLY to a memory stick thinking it will be safe, when in fact it is worse then not having a backup at all. Think about it, if you lose or damage the memory stick you have lost your data.

You need to keep the backup separate from the original. In case of fire or theft. Unforunately we have had customers who have lost both backups in these situations.

If you backup to an external device, such as a memory stick, and you consider the information to be sensitive then encrypt (password protect) the data. There are lots of other program out there what can do the same.

Pro Logic Computers (UK) Ltd as developed a backup solution for servers that meets all of the above. Please enquire for more details.

Bad Sectors
Is a damaged area on your hard drive. Your computer will have difficulty reading or writing information to this area. A bit like a scratch on a vinyl record. If the data is not put to another area of the hard drive there is a possibility you will loose it. We may recommend a new hard drive if Bad Sectors are detected as a precaution, else if the hard drive failed completely you will loose all data.


Basic Input Output System a small basic piece of software built into your motherboard that contains settings to allow your computer to function. These settings include the time & date and are powered by a small battery.


Boot / Reboot
The process were the device is powered on, initialised and ready for use. Reboot is the shutdown, power off and on for it to become ready for use again.


BSOD (Blue Screen of Death)
Officially known as a STOP Error. It’s were your windows has encountered a serious problem and stopped to prevent damage to your computer. Windows STOP error can occur due to failing hardware or corruption in your software.


Central Processing Unit (CPU / Processor)
This is the part of your computer that does the thinking, a quicker processer will mean your computer can process information quicker and speed up your computer.


Certificate of Authenticity (COA)
Genuine versions of Microsoft ® software come with a Certificate of Authenticity (COA). Microsoft ® Windows COA comes as a label (since Windows XP) that should be attached to your computer. This label contains a unique Product Key, this Product Key is a special code that is used if an install or reinstall of Windows is needed. It is important you keep this code safe as replacements are very expensive. It as been known on laptops to fade due to wear, so for this reason we would recommend you make a note of your product key.


Chain Mail
An electric version based on ‘chain letter’ were the recipient is encouraged to forward on copies of the email to several other email recipients.  These include Virus Hoaxes, Get Rich Schemes, Emotional Stories and even Jokes. Making you think the information will be valuable to other people by “the more people know the better”. Most are completely harmless, however the major concern is the replication of personal details within the email.

Chain Mail often contain lots of other recipient names, email addresses, email signatures, disclaimers, postal addresses and even telephone numbers.
By forwarding on a chain mail you are giving these personal details to other people and so on. Spambots can use these details to send Spam.
We recommend you do not forward on Chain Mail else you could eventually start setting spam and/or your email address be blacklisted as a spammer.
If you really need to forward on an email to multiple email addresses use Blind Carbon Copy (BCC) in your email program and remove any sender(s) personal details from the body of the email.


Check Disk
A process where we run a repair on the file structure of your hard drive. If for some reason the files in your hard drive are not what or where they should be (Corruption) then your computer may not function as expected.
Check Disk tries to repair these broken files. If these files are corrupted due to faults on your hard drive, known as bad sectors, Check Disk will move these files to a good area of the hard drive. However if this is the case we would normally recommend a hard drive replacement.


Main microchips (small intelligent components) on a mainboard are known as its Chipset. There are lots of different manufactures of chipsets and lots of different versions of these chipsets. If your mainboard gets replaced for repair or upgrade and has a different chipset from the original then your Operating System may get a little upset and become unstable. For this reason we would recommend a clean install of windows.


A command used to run Check Disk. See Check Disk for more details.


Clean Install
Is a complete wipe of your hard drive and just your Windows and Drivers installed on your computer. The basis on clean means no additional software, personal data, just the basics needed to make your computer work in Windows. If your computer has a recovery disk or partition we may use this see Factory Default.


Control Alt and Delete
This procedure can be used to recover from a program that as crashed or locked up, by closing the effected program in task manager.
It is done by pressing and hold the simultaneously CTRL and ALT keys down (found at the bottom of your keyboard) while tapping the DEL (found normally above the arrow keys in the middle of the keyboard). Once you have pressed the DEL key you can let go the CTRL and ALT.


Corruption / Corrupt Files
Corruption simply means that the data on your hard drive is not what it should be. Corruption can be fixed by either repairing the data or replacing the corrupted data with good versions.
Main reasons of corruption can be caused from and not limited to; viruses, failing hard drive, bad sectors, faulty RAM, not shutting down windows safely, power cuts, system crashes.


DC Jack
The point of a laptop or netbook where you plug in the charger. Due to wear and tear these DC Jacks can become loose and your laptop may start having problems charging. If this is the case we would recommend you have the DC Jack replaced as soon as possible before further expensive damage is cause.


The Desktop is the main screen of your windows (in simple terms). This is the area where you can see your personal desktop wallpaper, the icons on your desktop and the Task Bar (containing the Start Button, any running programs and the time). If you close or minimize all running programs then you will see you desktop. If you have multiple user profiles then you can have different customised desktops for each user.


Programs that control the hardware and allows you to use them. For example you will need printer driver to make your printer work. Drivers are very important and sometimes need to be updated to help stability and performance.


DVI Port
Stands for Digital Visual Interface. Some versions of DVI can carry both analogue and digital video signals. You can use adaptors to convert DVI to HDMI, and if the DVI is analogue compatible you can use an adaptor to convert it to VGA. This port can be used to connect your computer to a monitor or a TV, but you will need another cable or speakers for the sound. Also see HDMI Port and VGA Port.


Ethernet Cable
See Network Cable


Factory Default / Factory Reinstall
Almost like a Clean Install of Windows but using the computer manufactures recovery process. This will put your computer back to how it was when it was first made, with any preloaded software. Without any personal data, programs or hardware you have installed afterwards.


Your link to the outside world via the internet is like a massive motorway. Each lane of this motorway carries traffic in different directions and for different reasons. For example one of lane is used to send emails another to receive, these lanes are technically known as Ports.
Ports are used for all kinds of things that include; remote control of your computer, sharing files on a network, browsing the internet, playing online games.
A Firewall is designed to block traffic on the lanes (ports) that pose a risk such as remote control and sharing files on your computer, but allow traffic considered safe like emails and browsing.
However Firewalls can also block wanted traffic, like online gaming, other devices within your network and even the access to the Internet.
Firewalls come two versions, software (i.e. Security Software) and hardware (i.e. routers). Most routers have firewalls that block all incoming traffic. We would recommend you have a software firewall even if you are using a router.
Also See related terms Adware, Anti Virus, Malware, Rouge Anti Virus, Safe Surfing, Spam, Spambots, Spyware, Trojan horse and Virus.


A process to prepare a medium (such as your hard drive) for a clean start. For example formatting your camera’s memory card will remove all your photos and effectively make it empty for use again.

Locking Up
If the computer is not responding to either keyboard or mouse requests, but the mouse pointer moves, we call this ‘locking up’. Also see Freezing.


Mainboard / Motherboard
This is the main component in your computer that connects all other components together, hence the very important name of Main Board aka Mother Board. If a replacement main board is not the same type (namely chipset) then a clean install of Windows is usually recommended to ensure stability. Due to the nature of netbooks / laptops, mainboards can be the single most expensive item in a netbook / laptop, meaning they can be expensive to repair / replace.


Short for Malicious Software. The umbrella term for unfriendly versions of Adware, Spyware and other undesirable software.
Also See related terms Adware, Anti Virus, Firewall, Rouge Anti Virus, Safe Surfing, Spam, Spambots, Spyware, Trojan horse and Virus.

Network Interface Card (NIC)
Computers Network Interface Card is where you plug in a network cable. This allows the computer to communicate with other network devices and/or the internet via a router.


This is a term that we use that means we have backed up some/all of your data and put it in to a folder called oldhd.
The Oldhd folder may contain lots of files you need but also lots of files you don’t. We would advise you move any important data out of this folder in to your My Documents (for example).
This folder is located on your C: Drive and can be accessed via My Computer then Local Disk (C:).

If your BOIS finds a fault during POST your computer may just beep, display an error or sometimes just sit there with a blank screen.


Power Jack
See DC Jack


Power Supply Unit  (PSU)
For a netbook / laptop computer we regard the Power Supply Unit to be the charger you use the power/charge your netbook / laptop. These power supplies are commonly replaced due to wear and tear. Also see DC Jacks.
However Power Supply Units in PC’s are internal. Basically it’s the part you plug your mains lead in to. Power Supplies are sensitive to Spikes, Surges, Power Cuts and Electric Storms. We recommend you use an Anti Surge mains supply to try and protect your power supply and ALWAYS unplug ANY electrical sensitive equipment from the mains and telephone line if you suspect lightening to happen.


Preloaded / Preinstalled
Software that was installed on your computer when it was manufactured. You may not get the installation disks to reinstall these preinstalled products so it is important to make sure you keep your recovery disks safe. Some computers have the recovery built in to your computer and have the option of backing up this recovery to disks (recommended). If a clean install of Windows is done you loose the preinstalled software, unless the recovery can be used.


Product Key
See Certificate of Authenticity (COA)


Recovery Console
This is like a technician’s back door in to your computer when your computer will not boot. The Recovery Console allows us to run various procedures to try and repair your computer.


To install software again. Reinstall may be required to repair the effected software or driver to replace missing or corrupted files that the effected software is dependent on.


Rouge Anti Virus
Rouge Anti Virus software is becoming a very common problem. Basically it’s a con. Software pretending to protect you and falsely reporting your computer is infected, and then claiming it can remove the infections once you activate the software by paying for it.
Also See related terms Adware, Anti Virus, Firewall, Malware, Rouge Anti Virus, Safe Surfing, Spam, Spambots, Spyware, Trojan horse and Virus.

If your router is a ‘wireless router’ you can connect to it wirelessly (provided your computer has a wireless adaptor). You can also use a network cable to connect your computer to the router.
Most routers have firewalls built in to them to provide some extra protection from the internet.
It is recommended that your router is in the master telephone point in the property and is always powered on. If you are having problems connecting to the internet rebooting your router could help.


Safe Surfing
No matter how good or up to date your Anti Virus software is you still can get malicious infections. Why? If you use illegal or unofficial sites to download things ‘like’ unlicensed music, movies, software and/or cheats to games you maybe asked to install software to compliment this, this software can open up backdoors in to your computer and allow hackers or malicious software in to your computer. Because this activity is actioned and authorised by you, your Anti Virus software may assume it’s genuine and allow it through. We recommend any user of your computer does not use any software or visit any sites that promotes downloads of unlicensed music, movies, software, gambling, adult content and/or game cheats. If you sure the computer with family member we would recommend you make the other users limited accounts.

Screensavers started off in life to protect the screen (hence its name) initiated by inactive use of the computer in a specified time. By having moving images or just a black blank screen would prevent a long term still image being ‘burnt’ in to the screen leaving a ghost type image that couldn’t be removed. However this is not the case with modern LCD (flat screen) monitors. These days screen savers are used for cosmetic values or to stop someone seeing what’s on your monitor while you are away from your computer.


Refers to programs, drivers and even your operating system. Software can easily be damaged by; improper use, other software, failing hardware or viruses.
