Laptop Computer Based on Hardware and Software Needs

Choosing a Laptop Computer Based on Hardware and Software Needs

Laptop computers are one of the most desirable techie gadgets. A laptop is a portable computer that could comfortably be used while on a persons lap - hence the name. It contains all the basic and necessary software (like Office System and Internet access) and hardware (like CD-Rom drive and Modem) features of an ordinary computer and still fits in an ordinary briefcase or backpack.

Advantages of Owning a Laptop

1. Portability.

Being portable, it can be brought along and used anywhere - school, work, vacation trips, unlike the ordinary desktop computer. This is especially handy to a person with a very hectic schedule and busy lifestyle. In this regard, a computer addict doesnt have to be a hermit anymore! He or she can go out under the glaring rays of the sun and still hold on to the best technological breakthrough product.

2. Convenience.

It is useful for the working person, for the student, for the hobbyist, and for a computer addict too. One can take notes in class, type and print assignments and reports, access the Internet and communicate with another person on the other side of the globe. Teachers and public relations officers can make use of the laptop to give a different dimension to their presentations. Some teachers also find students are more motivated when using a laptop.

3. Size and Weight.

The dormer and studio type apartment lessee would agree that a laptop would save them more space.

4. Image.

It cannot be denied that a laptop is cool. With its sleek shape and form, it can be very eye-catching. It also gives the statement that the owner is not outdated, that he or she is in keeping with the times, and finally, computer literate.

Laptops are not that expensive anymore, but this is not the kind of item a person would shop for every other week. Each and every laptop has its own demands, requirements and features. Features you may want to look for:

1. Size and weight. Laptops are portable, but their sizes and weight still vary. To be very portable, it must be small and lightweight. They usually weigh 5 pounds. If it will be used outdoors more often, the weight should not be more than 5 pounds.

The size of the screen is also important. The usual sizes are 12.1, 13.3 and 14.4 inches. Tiny screens, as small as 8 inches, are ideal for portability, but the demands of the eyes - to have a squint-free screen - should also be considered.

2. Sturdy. A laptop must be taken care of, but it would be more ideal to have a tough and sturdy one that will be able to withstand any accidental knock or minor bump. There are models available with shock-resistant hard drive mounts. It has to be durable enough if it will be taken outdoors often.

3. Internet connection. One has to be in touch with the rest of the online community. There are wireless connections offered already. To one with budget constraints, an ordinary 56Kbps modem would do to connect to the rest of the world.

4. USB port. This should also be carefully checked out so that the laptop can be used in many more ways. There should be at least one USB port if not more, for future expansion of adding other hardware. The USB port can be used for external keyboard and mouse, but it is most useful to create connection with digital cameras, external drives, and MP3 players.

5. Battery life. The battery life of the laptop must allow the user to use and enjoy it outdoors or in areas that do not offer power resources for the public. A reasonable battery life should not be lower than 5 hours. The battery life will determine the extent of freedom that can be enjoyed with the laptop.

There are 3 kinds of batteries available.

The Lithium-ion (Li+) is usually chosen. Li+ batteries have range that can offer the best quality.

Nickel metal-hydride (NiMH) batteries are less expensive, although they do not excle in terms of battery life.

Nickel cadmium (NiCad) batteries are the ones to stay away from. They require constant recharging.

6. Technical specifications. There should be enough RAM, storage space / hard drive and computing speed. The technical specifications would depend on the most probable purpose of the laptop to the owner. If the laptop would be used for playing 3D games, it is ideal to get at least a 256 RAM. If several music or video files will be stored, a larger hard drive should be considered, 40 gigabyte is ideal.

7. Price. Finally, the laptop should be reasonably priced. There are refurbished laptops available out there for those with strict budgets but there is a way to save money and still get the ideal laptop.

First, the purpose that the laptop will serve must be properly ascertained. This will avoid purchasing laptops with expensive features that would end up being unused. Dont buy 80 gigabyte of storage space if only 3 gigabytes will be used for documents.

Stick to your budget. There are many attractive add-ons in the computer shop like glow-in-the-dark mouse pads or wireless mouse. These may not be necessary and can add to the total cost.

Negotiate for add-on features. Lastly, it wouldnt hurt to try to negotiate for the price. 5% off can go a long way.

Full information about computer storage devices

Hello again my friends the last lesson we talk about Ram, ROM and cached memory .This lesson we will talk about storage devices in computer. Lets start now.

Storage Devices

The volumes are the units that can keep your data and programs and those units are divided into: solid cylinders, and floppy discs, CDs (laser CDs), and the multifaceted digital roller, and the magnetic strip, and flash memory.

Hard Disks

A small unit in the size of the palm of the hand almost always exist in and installed in the central processing unit (CPU) and the cylinder characterized by sizable storage capacity as they reach the storage capacity to store more than ten thousand books any nearly ten billion character.

Floppy Disks

There are two types 3.5-inch floppy discs are now used in the process of saving data view of their small size and the large size of the storage capacity flexible cylinders 5.25 is no longer used now concision consider the small size of the amplitude storage and large size.

Compact Disks (CD)

CDs or laser discs are the latest means of storage where they are used to store audio and video clips, where storage capacity of up to 650 six hundred and fifty million characters. The disadvantage of this quality that they can not register only once and only one.

DVD Digital Versatile Disk

It is a type of high-capacity CDs used to store 2.10 GB of information. And used compact disc (CD) to store music, usually used to store high-quality movies instead of video tapes

Magnetic Tape

This type of storage media similar to what we see in the world of audio cassettes magnetic audio recorder and based on the same technology information is stored in the form of magnetic points sequentially, and these strips are commonly used in save backups of data.

Flash Memory

Is a memory used to store data and is characterized by its small size and large storage capacity, where up to more than GB, can also scan data from them and write them more than once and is connected to the computer by USB.

After explaining parts Computer physical detail must clarify the relationship and the extent of interdependence of each part with the other to carry out operations required from the computer example for doing arithmetic what first must enter numbers by Input units are then processed by the control unit Central to get the results that are brought out of During the output units, and stored by the storage units and the following figure illustrates the interdependence of computer parts with each.

My friend now we finished the first part of computer components (Hardware Components) the next lesson we will talk about computer software part .To be continued .Thank you

10 Easy Steps to Speed Up Your Computer Without Upgrading

By Jim Shutes
Lapeer Tech Group

It seems that the longer you own your computer, the slower it gets! A lot of people will keep their computer until it gets so slow that they feel they need a newer, faster model. Some feel like the reason it is getting slower is because it is getting older, when that is just not the case. Your computer should run just as fast as the day you brought it home – if you follow these 10 Easy Steps to Speed Up Your Computer.
1. Empty the Temp directory regularly. After a short while, the temp directory fills up with hundreds of temp files that always get scanned over when Windows starts up and when programs launch. This slows everything down immensely.

Rule of thumb for Temp Files: If you don’t have any programs open (and nothing minimized in the bar below), then you shouldn’t have ANY temp files in your temp directory. If you do, delete them.

To delete Temp files, make sure NO programs are open, and…

a. In Windows 95, 98 or Me, go to C:WindowsTemp and delete everything inside the Temp folder.

b. In Windows 2000 or XP, it is a little trickier. First, make sure that you can see hidden folders. Double-click My Computer. Click on the Tools pull-down menu, and then on Folder Options. Click on the View tab. Scroll down and click on Show Hidden Files and Folders. Click Ok. Now you can go to the C:Documents and SettingsAdministratorLocal SettingsTemp folder. Delete everything here.

2. Empty the Temporary Internet Files regularly. To empty Temporary Internet Files, go to your Control Panel and double-click the Internet Options icon. Choose to Delete Cookies, and to Delete Files. This will clear all of your Temporary Internet Files.

3. Check your hard disks for problems.

a. For Windows 95, 98, or Me, double-click My Computer. Right-click the C-drive and click on Properties. Click on the Tools tab and choose to check the computer for problems. If you choose to do a Thorough Scan, this will do the hardware check for physical disk damage or sector damage. Choose to fix any errors it finds.

b. For Windows 2000 and XP, double-click My Computer. Right-click the C-drive and click Properties. Click on the Tools tab and choose to check the computer for problems. Click on Check Now. You will then have two check boxes. The top option is for the file check, and the second option is for the hardware (physical disk) check. Check either one, or both. At least check the top one. Hit ok, and reboot. This may take some time, but let it run.

4. An even more thorough disk check, would be to use a 3rd party utility. One of my favorites is TuneUp Utilities 2004. It does cost $39.99, but they do offer a FREE download trial of 15 days. This program does a really good job of fixing software and physical hard drive problems. It also tunes up your system for increased speed, and streamlines your operating system for peak performance. Download it HERE... http://www.lapeertechgroup.com/downloads.asp

5. Or, you can do a few of the performance tweaks yourself, if you have Windows XP. By default, EVERYTHING is turned on in Windows XP. It isn’t very streamlined for performance, but rather for appearance. You can turn off a few of the unnecessary features, and Windows will still work just fine, and maybe a little faster.

To do this, right-click on My Computer and click on Properties. Click on the Advanced tab. Under the Performance section, click on the Settings button. On the Visual Effects tab, you will see a list of check boxes. By default, these are all on. You really don’t need any of them for Windows to run. Go through the check boxes one by one, and determine which ones you can and can’t live without.

6. Turn off Active Desktop. Active Desktop turns your desktop into a web page, and allows you to have things like a real-time calendar, and up-to-the-minute weather or stocks. These are nice, but really slow down your computer. And even if you don’t use Active Desktop for anything, just having it active can cause a performance decrease. Turn it off.

a. In Windows 95, 98 and Me, right-click on the desktop and in the pop-up menu, choose Active Desktop. Inside that option, uncheck Active Desktop. If there is no check next to it, then it isn’t on. Don’t choose it. Instead, just click the desktop again to get out of the menu.

b. In Windows 2000, right-click on the desktop and in the pop-up menu, choose Active Desktop. Inside that option, uncheck Show Web Content. Again, if there is no check next to it, then it is not on. Do not check it.

c. In Windows XP, right-click on the desktop and in the pop-up menu, choose Properties. On the Desktop tab, choose Customize Desktop. Now, on the Web tab, make sure that there are no websites chosen here. If there aren’t any, then Active Desktop is not on. Cancel and go back to the desktop.

7. Install and run a good AntiVirus program to keep out viruses that can take over your system. One of my favorites is AVG. It is not only a really good AntiVirus program, but it is also FREE! If you don’t have any AntiVirus software on your computer, get AVG AntiVirus NOW by downloading HERE... http://www.lapeertechgroup.com/downloads.asp

8. Get rid of Spyware. A lot of computer users have Spyware and don’t even know they have it, much less how to get rid of it. If your computer has been taking you to websites that you don’t want to go to, or if you get pop-ups when you aren’t even on the Internet, or if your computer has been running extremely slowly lately, for no reason, you probably have Spyware.

On all of the computers that I setup, I install two different AntiSpyware programs: AdAware SE and SpyBot. These two programs are highly recommended by TechTV (G4) and other computer authorities (including my own research on Spyware) and work very well together. They compliment each other and catch Spyware that the other misses, but together, do a very good job.

Get SpyBot HERE... http://www.lapeertechgroup.com/downloads.asp. Download all updates and run the Immunize option a couple of times.

AdAware SE does a good job when you keep up on the updates and manually scan your system with AdAware. Get it HERE... http://www.lapeertechgroup.com/downloads.asp

In some cases, when the Spyware has become too entwined into your system, even a computer repair technician can’t get rid of the Spyware. At this point, it is better to just backup only what you need and have the operating system reinstalled. Believe me, when your computer gets to this point, you don’t want to just put a “band-aid” on it. Just start from scratch with a clean system. It’s the best way to go.

9. Streamline MSCONFIG. One thing that really causes a HUGE performance decrease is to have unnecessary programs running in the background. Some of these programs can be seen in your System Tray (located next to the clock). These are tiny programs that are robbing you of memory and processing power. Some of them you need, while most you don’t. Some of the programs you DON’T need are printer icons, CD burning icons, shortcuts to programs (such as video settings), AOL, any Instant Messaging Programs, etc. Just because these programs aren’t always running, doesn’t mean that you still can’t print, burn CDs or Instant Message. They can all be run from a shortcut.

You can use a utility, called MSCONFIG, to turn OFF unnecessary Start Up items.

a. In Windows 98, Me, and XP, click on StartRun and type msconfig. Click on the Startup tab. This is a list of everything that is running in the background, some of which show up in the System Tray. Now, be careful, some of these you do need. Some items to keep are Ctfmon.exe (XP), Scan Registry (Win98, Me), Task Monitor (Win98, Me), System Tray (Win98, Me), LoadPowerProfile (Win98, Me), Rundll.32, any AntiVirus programs (such as McAfee, Norton, or AVG). Others, you can uncheck, such as NeroCheck, ypager, qttask, AOL, and any other Instant Messaging programs, or printing programs. Remember, if something doesn’t work, because you turned it off, it can always be turned back on. You just have to reboot every time you make a change here. But, as you uncheck the unnecessary programs that run in the background, you will see that Windows loads much faster, that there are less icons in the System Tray, and that your system is much more “snappy” and quick to respond.

b. In Windows 2000, MSCONFIG wasn’t supplied. You actually have to download and run an MSCONFIG utility. Download the MSCONFIG utility HERE... http://www.perfectdrivers.com/howto/msconfig.html.

After you reboot, you will have a window that says that the configuration utility was edited. Just check not to show that in the future, a check box at the bottom. This just means that there was a change made to the MSCONFIG.

10. Defragment your hard drives. NOTE: to efficiently defragment a hard drive, it likes to have 25% free space. It can still do the defragmentation with only 15% free space, but it takes quite a bit longer. If you can, delete any unnecessary files before deframenting your drives.

a. To defragment your hard drives (in any Windows operating system), double-click on My Computer. Right-click on the c-drive and click on Properties. Click on the Tools tab and choose the bottom button, to Defragment Now…

computer input units lesson 1

Hello my friends from all the world , I created this blog to help all my friends that have a little knowledge about computer .I will explain to my friends all things about computer .Dont worry I will explain from the begging with zero- level computer .After you follow my lessons , I believe you will be professional in few months. My dear friends please help me to share this lessons for all your friends .We dont want anyone to feel sad because he isnt know any thing about computer .Thank you my friends ,Now lets begin our lesson .

Computer Components

Computer Components is divided into two parts:

Hardware components
Software components

Now lets explain each part in details, we will begin with the first part now.

Computer Hardware Components

Physical units is any molecule that is tangible and visible in the computer or connected to the computer. Physical units are divided into three sections, called:

Input units
Output units
CPU means central processing units

Dont worry my friends i will explain every part in details, so lets begin with input units.

Input Units

Namely those devices and units responsible for data entry and various programs for the device. These units examples like :

Keyboard
Mouse
Scanner
Microphone
Digital Camera
Disk Drives

Now you understand what is the input units and what is the function of it .Lets explain in details what is the input units components and what do every component in computer .

Keyboard

The keyboard is one of the most important units of data entry for computer. And use the keyboard to enter data from letters and numbers. The keyboard contains the following:

Switches characters and symbols like (1,2,3,a,b,c,!,@,#,$,%,....,etc )
Number pad keys used to enter numbers and calculations.
Arrow keys, which are used to move the cursor of writing.
Shift (Shift) used to enter characters and symbols written highest buttons writing has other uses.
Keys change language (Alt + Shift). Terms used keys (Alt + Shift) in the right side of the keyboard to change the writing language to English. The keys (Alt + Shift) in the left side of the keyboard Fertilizer writing language to English.

Mouse

Is a unit of computerization and mouse has two buttons left and right. The button is located in the middle of some species. When you move the mouse pointer moves the mouse in all directions on the screen and is in the form of shares. And mouse has three uses:

signal (Pointing) so that you can refer to anything on your screen
Selection (Selection) by clicking the left mouse button while the signal on a certain thing on the screen.
(Move) constantly pressing the left button of the mouse to drag the thing that you want to move to a new location and this process is called drag and drop (Drag and Drop).
Right click used to show the properties of the file, if you want to make rename of file or delete and other functions.

Scanner

The scanner is one of input unit computerization and is connected to the computer to upload images and graphics of all kinds so you can see it on the screen and re-use and change.
