Basic Computer Terms

Server- A server is a computer on a network that acts as an administrator.  Servers sometimes act as gateways for other computers on a network. Generally servers are used on network with more than a few computers.

Mother Board- As the name implies the motherboard is the part of the computer where everything is connected.  All parts of the computer connect to the motherboard.

Mouse-  The mouse is a part of the computer that acts as a selector tool. Users use the mouse to highlight different texts and to open and control windows.

Keyboard- An input device that allows users to input text into a computer.

Byte – A binary number that the computer reads as data. 1000 bytes=1 kilobyte (KB), 1000 KB = 1 megabyte (MB), 1000 MB, = 1 Gigabyte( GB),  1000 GB = 1 Terabyte(TB)

Multi-processor (Dual Core, Quad Core)- Multi-processors are processors with multiple components that act simultaneously to process data. A multi-processor can process more data per second than regular processors. Many computer companies today use multi-processors for their computers.

Power Supply- The power supply unit is the part of the computer that directs power to the computer and individual components.

Monitor- The monitor is the display screen of a computer. This is a component that allows users to visually interact with a computer. Most monitors today are LCD (liquid crystal display); reducing the size of the monitor while also maintaining size and functionality.

Speakers- Speakers allow for audio files and other sound to be heard from a computer.

Firewall- A firewall is generally used to permit or deny access to network transmissions to protect against unauthorized access to a network. Many personal computers have firewalls to protect against threats from the internet.

Registry- Saved settings for how Windows stores configuration settings and options.

Wireless Adapter- An adapter that can be inserted into a computer for the computer to be able to access a network or the internet wirelessly.

VGA cable- The basic cable used to connect a computer to a monitor.

Start menu- The start menu will allow access to all the programs available on a computer. Generally an icon with the word “start”  or a plain icon with the windows logo.

Software-A set of programs that tell a computer what and how to do something. Software is usually not something a person will be able to physically touch. For example, software like Microsoft Office is a collection of programs that allow users to create different types of files.

Hardware- The physical parts of a computer. An example of hardware is a monitor.

 

Seven Good Reasons to Upgrade to Firefox 7

By Katherine Noyes, PCWorld

Six weeks to the day after the official release of Firefox 6, Mozilla on Tuesday rolled out Firefox 7, the next version of its popular Web browser for Windows, Mac, Linux and Android users.

The new release comes as part of the rapid release schedule Mozilla implemented for Firefox earlier this year, by which users are offered upgrades every six weeks.

Business users who want less-frequent updates will soon have a slower alternative schedule, as I noted last week. The first such enterprise-focused Extended Support Release (ESR) version of desktop Firefox is expected to be based on Firefox 8 or 9 later this year.

In the meantime, there are plenty of reasons to make the switch to this newest version, which is now available as a free download. Many of them, in fact, boil down to one key thing: faster speed.

1. Memory Management

Ever since Firefox 7 entered the Aurora channel back in July, its primary focus has been speedier performance and better use of memory, and that emphasis is apparent in the software released today.

Firefox 7 manages memory more efficiently than its predecessors did, Mozilla says, for a speedier Web browsing experience. “Users will notice Firefox is faster at opening new tabs, clicking on menu items and buttons on websites,” the organization says. “Heavy Internet users will enjoy enhanced performance when lots of tabs are open and during long Web browsing sessions that last hours or even days.”

A new Mozilla Hacks blog entry posted today offers several key metrics demonstrating Firefox’s new nimbleness.

2. More Speed

New tools included in Firefox 7, meanwhile, are designed to make it easier for developers to build speedy Web experiences for users. A new version of hardware-accelerated Canvas, for instance, speeds up HTML5 animations and games in the browser, allowing developers to build more compelling and interactive Web experiences.

Firefox now also supports the W3C navigation timing spec API so developers can measure page load time and website navigation against bandwidth speed, website traffic and other factors. This API allows developers to test user experiences remotely and easily so they can quickly optimize websites and Web apps for different types of users.

3. A New Performance Tool

Focusing on future speeds, Firefox 7′s new Telemetry tool collects performance feedback so as to help Mozilla make future Firefox releases even faster.

“Firefox 7 marks a turning point in how we measure Firefox performance,” reads a Mozilla Hacks blog post from this morning on the topic. “Traditionally we measured Firefox performance on individual developer machines and our build & release infrastructure. However it turns out synthetic benchmarks do not correspond to real-world Firefox usage: it is difficult to model a ‘typical’ computer in a lab environment.”

Exceptionally slow consumer hardware, changes in usage patterns and preinstalled “bloatware” can all affect Firefox performance in unexpected ways, the post notes.

The browser’s new Telemetry tool will prompt users to opt into reporting performance data to Mozilla. “This data will supplement our existing benchmarking infrastructure to help us optimize future Firefox releases,” the post explains.

Telemetry performance metrics are very lightweight, however, and will not negatively impact Firefox performance, Mozilla says.

4. Add-On Compatibility

When Firefox 6 launched, 97 percent of add-ons compatible with Firefox 5 were still compatible with version 6, according to Mozilla add-ons product manager Justin Scott, who wrote a blog post yesterday on the topic.

Not only that, but “we’re on track to launch Firefox 7 tomorrow with 99 percent compatibility from 6,” Scott added. With Firefox 8, which will reach beta later this week, compatibility issues should improve even more, he wrote.

Add-on users can also install Firefox’s Add-On Compatibility Reporter to flag any problems with the software they use.

5. A Cross-Platform Approach

By supporting tools like WebSockets across desktop and mobile platforms, Firefox lets developers create faster, seamless Web applications for use on mobile phones, tablets and computers. Firefox also now supports the W3C navigation timing spec API across desktop and mobile platforms, so developers can optimize websites and Web apps for different types of devices, platforms and networks.

A number of features in Firefox for Android, meanwhile, are designed to make it faster to browse the mobile Web, such as the ability to copy any website text and paste it into emails, website forms and SMS messages.

6. Free, as in Beer

Firefox is free in more ways than one. First and foremost is that it costs you nothing to install, use or upgrade–a winning feature by most accounts, though certainly not Firefox’s only one.

7. Free, as in Freedom

Perhaps even more important, though, is that Firefox is open source software and so it doesn’t restrict your use of the browser in any way. There’s no vendor lock-in, and it’s eminently flexible and customizable to your needs.

Also significant is that Mozilla is what it calls a public benefit organization, existing not to make money but to make the Web better for everyone.

Speed Up Windows by Stripping It Down

Windows has plenty of features that you can turn off to speed things up. Here’s how to find the features you don’t need.

By Lincoln Spector, PCWorld

Windows can do all sorts of amazing things, some of which you might actually want it to do. Unfortunately, the things you don’t want it to do can slow it down. By turning off unnecessary programs, processes, and services, you can unburden Windows and help it live up to its full potential.

Some of the following suggestions may not produce a noticeable improvement in performance individually. But their cumulative effect can be to speed up your system significantly.

You don’t have to turn off all of these features, mind you. Most of them are useful–or at least aesthetically pleasing–to some people, but pointless to others. I’ve tried to provide enough information to enable you to make an informed decision about which ones to keep.

To help you follow my suggestions more easily, I’ve organized the questionable features in my list by the Windows location where you must go to turn them off. That way, you won’t have to visit the Windows Features dialog box, or Services, more than once.

The System Properties Dialog Box

You can turn off many features from the System Properties dialog box.You’ve almost certainly been here before. This is where you change your network ID, manage System Restore, and launch Device Manager. You can also shut off some unnecessary features here.

To get to the System Properties dialog box in Vista or Windows 7, click Start, right-click Computer, and select Properties. Then click one of three links–Remote settings, System protection, or Advanced system settings–in the left pane.

Alternatively, click Start, type sysdm.cpl, and press Enter.

In XP, click Start, right-click My Computer, and select Properties. Or click Start, Run, type sysdm.cpl, and press Enter.

Unnecessary Cosmetic Features: XP, Vista, Windows 7

Windows doesn’t have to look as pretty as it does to do its job. And some aesthetic compromises can free up precious processor clock cycles for real work.

To see your options for turning off these extras, click the System Properties dialog box’s Advanced tab, and then click the Settings button inside the Performance box.

This brings up another dialog box, where you can select which visual effects to keep and which to lose. Select Adjust for best performance to turn off all of them, or individually uncheck the ones you don’t care for.

Error Reporting: Windows XP

Turn off Error Reporting to speed up XP a bit.You’ve probably noticed that both Windows and the programs that run on it occasionally make mistakes. When that happens, the operating system attempts to send a report back to Microsoft. In theory, your report helps the company find bugs and improve future versions.

Whether that reporting system really helps is open to debate. It certainly doesn’t help you in the short run.

If you’d rather get on with your work after something goes wrong, you can disable error reporting. To do so in XP, click the System Properties dialog box’s Advanced tab, click the Error Reporting button in the lower-right corner, and select Disable error reporting. I recommend keeping ‘But notify me when critical errors occur’ checked.

You can also turn off error reporting in Vista and Windows 7, but not from this dialog box. I explain how to proceed in the Services section.

Remote Assistance: XP, Vista, Windows 7

If you’re not providing or receiving long-distance support, or if you use a third-party tool to provide that support, there’s no reason to leave the Remote Assistance feature on.

To turn it off, click the System Properties dialog box’s Remote tab. Uncheck Allow Remote Assistance connections to this computer (in Vista or Windows 7) or Allow Remote Assistance invitations to be sent from this computer (in XP).

Windows Features Dialog Box

This handy box, semi-hidden in Vista and Windows 7, gives you on/off control over a multitude of features. You can control what games are available, turn on RIP Listener (which isn’t nearly as macabre as it sounds), and turn off some resource-wasting services.

XP users can skip this section, entirely–this dialog box was added with Vista.

To open the Windows Features dialog box, click Start, type programs and features, and press Enter. Once the ‘Uninstall or change a program’ application comes up, click Turn Windows features on or off in the left pane.

Windows 7 users can take a quicker alternative route: Click Start, type windows features, and select Turn Windows features on or off.

One warning: This dialog box takes a long time to load; and when you’re done with it and click OK, it takes an even longer time to close. Then it usually reboots the PC. Consequently it’s best to make all of these changes at one time.

Internet Printing Client: Vista, Windows 7

Don’t use Internet Printing? Turn it off.Do you ever print documents over the Internet? If not, you’re unlikely to miss Windows’ Internet Printing Client. To turn it off, first find and expand the Windows Features dialog box’s Print Services (or Print and Document Services) listing. Then uncheck Internet Printing Client.

Windows Meeting Space: Vista

If you’re working on collaborative projects with other Vista users, Meeting Space is a handy program to have around. It lets you share files across a network while editing them with a remote colleague. A lot of people were disappointed with Microsoft dropped Meeting Space from Windows 7.

But, if you’re not working on collaborative projects with other Vista users, Meeting Space is just a waste of resources. To disable it, simply uncheck Windows Meeting Space in the Windows Features dialog box.

Tablet PC Extras, Part 1: Vista, Windows 7

Turn off Tablet PC extras, part 1.In the long-ago days before the iPad, a tablet PC was a laptop with a touchscreen that could rotate 180 degrees and fold down over the keyboard. With those rather bulky and heavy tablets in mind, Windows offers some very good tools for touchscreen interfaces.

I’m actually writing this article on such a computer, and though I seldom fold it down into tablet mode, I wouldn’t dream of turning off those enhancements. However, if your computer lacks a touchscreen, you have no reason to leave them on.

This is a two-step process that starts in the Windows Features dialog box. Start by unchecking Tablet PC Optional Components (Vista) or Tablet PC Components (Windows 7).

Services

The first time you look at the Services window, you may feel that you’re getting deeper into geekdom than you ever wanted to go. But calm down–it’s really not that difficult.

To enter Services in Vista or Windows 7, click Start, type services, and press Enter.

In XP, select Start, choose Run, type services.msc, and press Enter.

The window that comes up can seem intimidating. It lists a great many services (nearly 200 on my PC) that various programs need to help them do their job. The problem is that some of the services that are running in the background could just as well be sleeping.

Double-click a service and up comes its Properties dialog box. One option on the General tab, ‘Startup type’, controls how the service starts. Select Automatic, and it loads when Windows boots. Select Manual, and it loads when a program needs it. Select Disabled, and it won’t load at all.

Tablet PC Extras, Part 2: Vista, Windows 7

Turn off Tablet PC extras, part 2.I’ve already discussed why you should or should not turn this set of features off, and I’ve described how to do the first part of the job. Now comes the second part. In Services, find and double-click the Tablet PC Input Service. In the ‘Startup type’ drop-down menu, select Disabled, and then click OK.

ReadyBoost: Vista

In theory, plugging a flash drive into your PC and letting ReadyBoost take control of it will speed up your PC. I have my doubts.

But if you aren’t using ReadyBoost to speed up Windows, the feature is slowing it down. In that case, you’ll be happier turning ReadyBoost off entirely.

In Services, find and double-click ReadyBoost. In the ‘Startup type’ drop-down menu, select Disabled, and then click OK.

XP doesn’t have ReadyBoost, and Windows 7 doesn’t allow you to turn it off.

Search Indexing: XP, Vista, Windows 7

Indexing speeds up Windows’ searches considerably, especially in Vista and Windows 7: An indexed search can take seconds, while a nonindexed search can take minutes. But when you’re not searching, indexing drags down performance.

If you almost never search for files, or if you use a third-party search tool like Copernic Desktop or Google Desktop, consider turning off search indexing. Otherwise, leave it on.

The service you want to turn off is called Windows Search in Vista and Windows 7, and Indexing Service in XP. To turn it off, select Disabled.

Error Reporting: Vista, Windows 7

I’ve already discussed how to do disable this feature in XP. To switch it off in Vista or Windows 7, you’ll need to disable it in a different location.

Windows reports errors back to Microsoft, in order to gain information for later bug fixes. The trouble is that this reporting operation slows down your PC at the moment when you’re most annoyed by it.

If you’d rather speed up your PC than help Microsoft debug software that it has already sold to you, find and double-click the Windows Error Reporting Service. In the ‘Startup type’ drop-down menu, select Disabled.

Fast User Switching: XP

No, I’m not suggesting that anyone switch you with a faster user.

This service helps Windows keep two or more users logged on and active at a time. That’s useful and convenient…provided you’re sharing the PC with another person.

If the PC is all yours, find and double-click the Fast User Switching Compatibility service, and set the Startup type to Disabled.

Help and Support: XP

You shouldn’t turn this one off entirely. After all, if you need help for an XP component, the last thing you want is to get an error message instead.

But unless you constantly use Help, you won’t want it to be running until you need it. So in Services, find and double-click Help and Support, and select the Startup type Manual. That way, Help and Support won’t load until you ask for it.

Offline Files: Vista and Windows 7 (Business and Ultimate Editions Only)

If you work on files stored on a server whose availability you can’t depend on, Offline Files makes your life easier by copying the files to your hard drive and keeping them synced.

But if you don’t work on such files, there’s no point in keeping the feature activated. Find and double-click the service Offline Files. In the ‘Startup type’ drop-down menu, select Disabled, and then click OK.

This feature isn’t available in any of the Home editions of Vista or Windows 7.

The Desktop

The features that you can disable here are the easiest ones to turn off–and switching them off is likely to yield the biggest improvements in performance, too.

Aero: Vista, Windows 7

Turn off Aero in Vista, step 1.With Vista, Microsoft gave Windows an attractive, transparent look that it dubbed Aero. With Aero on, the headers at the top of each window are slightly transparent. You can’t see what’s behind them clearly enough to read them, but it gives the desktop a nice, three-dimensional look.

But that look eats clock cycles, and depending on the speed of your PC and your willingness to trade performance for aesthetics, you might want to turn Aero off.

Turn off Aero in Vista, step 2.If you’re using Vista, right-click the Windows desktop and select Personalize, Window Color and Appearance. Click the Open classic appearance properties for more color options link (if you don’t see the link, Aero is already off).

Turn off Aero in Windows 7. In Windows 7, right-click the Windows desktop and select Personalize. Select one of the themes that are displayed under the ‘Basic and High Contrast Themes’ heading.

The Sidebar: Vista

That bar full of widgets on the right side of the Vista desktop must have seemed like a good idea at the time. Who wouldn’t want a feature that distracts you when you need to concentrate, steals precious screen space, and slows system performance like an anvil chained to a swimmer’s leg?

Someone must have complained, because Microsoft didn’t include the Sidebar in Windows 7.

Unlike the other features in this article, this one has no possible redeeming value. I’m not suggesting that you consider turning this feature off; I’m urging you to turn it off without further consideration.

To remove the Sidebar, Right-click a blank space on the Sidebar and select Properties. Uncheck Start Sidebar when Windows starts.
