The difference between laptops and tablets

Programs

Laptops are a mini computer and act just like a desktop. This means you can run the same programs that are designed for large desktops on a laptop just fine.  This is not the case for many tablet computers.  Many tablets and phones will only run “apps” which are different then desktop computer programs.

Keyboard

The first very clear difference between a tablet and a laptop is the absence of a keyboard. If your tasks don’t involve typing, or only involve a small amount of typing, then you can safely ignore this as a drawback. If you collect a lot of data door-to-door, as some professions do, then a small hand-held will almost certainly be better.

For writing or number-intensive tasks then a keyboard is a given requirement. Voice control is good but many people will prefer an old-fashioned key-it-in approach. There are keyboards and keyboard cases for tablets but these vary in performance; early models tended to make characters appear a split second before they were typed, for example. Go to a shop and try one out; keyboard cases that hold plenty of charge are available for seven inch tablets and they work well, but the physical size means they’re small and cramped to use.

They also require independent charging which means organising yourself so that they don’t conk out while you’re in the middle of something. And keep an eye on the cost. A tablet plus keyboard case might well end up costing as much as a full-blown laptop.

External storage

One advantage of a laptop is its ability to use external storage media. If you have a large file on an external drive and can plug it in via USB, great – but this may not be possible without at least an adapter for your tablet, depending on which model of tablet you’re using. And if you wanted to use a CD drive it’s far simpler if it’s built in to your computer (although these are being phased out on some laptops as well – an external CD drive connected through USB will still work).

File system

Related to external storage is internal storage. Download a file to your laptop, find the downloads file and you can send it to someone else. Download the same thing to your tablet and good luck finding where it’s put it. Picking up more than one document and sending it by email starts to require a new app to help you work out just where they’re located on the disk.

This isn’t a criticism – the essence of tablet computing is that it’s supposed to hide some of the complexities from the person using it. They’re supposed to be as easy to use as your phone and that means the manufacturers are going to conceal as much under the bonnet as they can. Which means you’re going to get a slightly cut-down version of a computer when you use one.

Is my data and information secure on the internet and cloud? – Longmont Computer Repair

We often get the question “Is my data and information secure on the internet and cloud?”   The answer is NO!

Below is a letter from Brendan Eich – CTO of the Mozilla Firefox web browser which explains why this is the case:

“It is becoming increasingly difficult to trust the privacy properties of software and services we rely on to use the Internet. Governments, companies, groups and individuals may be watching us without our knowledge. This is particularly troubling when such surveillance is done by governments under statutes and laws that provide limited court oversight and almost no room for public scrutiny.

As a result of laws in the USA and elsewhere, prudent users must interact with Internet services knowing that despite how much any cloud-service company wants to protect privacy, at the end of the day most big companies must comply with the law. The American government can legally access user data in ways that might violate the privacy expectations of law-abiding users. Worse, the government may force service operators to enable surveillance (something that seems to have happened in the Lavabit case).

Worst of all, the American government can do all of this without users ever finding out about it, due to gag orders.

The Internet defined

Computer Physicians, LLC Colorado customers frequently ask many questions about their computers.   Therefore we have created a blog to help customers understand some topics in the computer and internet world.

What is the internet?

The Internet Is a Big Network of Computers.

The Internet is named for “interconnection of computer networks”. It is a massive hardware combination of millions of personal, business, and governmental computers, all connected like roads and highways. The Internet started in the 1960’s under the original name “ARPAnet”. ARPAnet was originally an experiment in how the US military could maintain communications in case of a possible nuclear strike. With time, ARPAnet became a civilian experiment, connecting university mainframe computers for academic purposes. As personal computers became more mainstream in the 1980’s and 1990’s, the Internet grew exponentially as more users plugged their computers into the massive network. Today, the Internet has grown into a public network of millions of personal, government, and commercial computers, all connected by cables and by wireless signals.

No single person owns the Internet. No single government has authority over its operations. Some technical rules and hardware/software standards enforce how people plug into the Internet, but for the most part, the Internet is a free and open broadcast medium of hardware networking.

2: The Web Is a Big Collection of HTML Pages Within the Internet.

The World Wide Web, or “Web” for short, is the very large subset of the Internet dedicated to broadcasting HTML pages. The Web is viewed by using free software called web browsers. Born in 1989, the Web is based on hypertext transfer protocol, the language which allows you and me to “jump” (hyperlink) to any other public web page. There are over 90 billion public web pages on the Web today, and over 300 billion private (‘invisible’) web pages.

The Benefits of Networking with Computer Physicians

Computer Physicians, LLC Colorado customers frequently ask many questions about their computers.   Therefore we have created a blog to help customers understand some topics in the computer and internet world.

What are the Benefits of Computer Networking with Computer Physicians?

The most obvious benefit of computer networking is that you can store virtually any kind of information at, and retrieve it from, a central location on the network as well as access it from any connected computer. You can store, retrieve, and modify textual information such as letters and contracts, audio information such as voice messages, and visual images such as facsimiles, photographs, and even video segments.

A network also enables you to combine the power and capabilities of diverse equipment and to provide a collaborative medium to combine the skills of different people—regardless of physical location. Computer networking enables people to share information and ideas easily, so they can work more efficiently and productively. Networks also improve commercial activities such as purchasing, selling, and customer service. Networks are making traditional business processes more efficient, more manageable, and less expensive.

COST-EFFECTIVE RESOURCE SHARING

By networking your business computers you can reduce the amount of money you spend on hardware by sharing components and peripherals while also reducing the amount of time you spend managing your computer system.

Equipment sharing is extremely beneficial: when you share resources, you can buy equipment with features that you would not otherwise be able to afford as well as utilize the full potential of that equipment on your network. A properly designed network can result in both lower equipment costs and increased productivity.

Suppose that you had a number of unconnected computers. Employees using these computers would not be able to print unless you purchased a printer for each computer or unless users manually transferred files to computers with printers. In this scenario you would be choosing between hardware and labor expenses.

Networking the computers would give you other alternatives. Because all users could share any networked printer, you would not need to buy a printer for every computer. As a result, instead of buying numerous inexpensive, low-end printers that would sit idle most of the time, you could buy a few inexpensive printers and a few printers with high-end productivity features. The more powerful printers would be able to print more rapidly and with better quality than the less expensive ones. In addition, the more powerful printers might also be able to print in color and to sort, staple, or bind documents.

When you select the right mix of printers and assign each network user appropriate access to them, you have enough printing power to address the needs of all of your employees. Rather than leave expensive equipment idle, you provide your employees with the latest, most powerful productivity features—all for a significantly lower cost than if you were to purchase an inexpensive printer for each workstation on the network.

A network enables you to share any networkable equipment and realize the same benefits that you would enjoy from sharing printers. On a network, you can share e-mail systems, modems, facsimile machines, data storage devices such as hard disks and CD-ROM drives, data backup devices such as tape drives, and all network-enabled software. When you compare the costs associated with sharing these resources to the costs of purchasing them for each computer, the savings can be enormous.

A network also enables you to save money on software. Instead of buying separate copies of the same application for various machines, you can purchase one copy with enough user licenses for your network. In large businesses the amount of money saved on software is substantial.

Finally, you will also be able to reduce your administrative overhead. On a computer network, updates to software, changes in user information, and network security can all be accomplished from one location. With standalone computers you would be required to make these updates on each individual computer workstation.

What is Data Recovery?

Computer Physicians, LLC Colorado customers frequently ask many questions about their computers.   Therefore we have created a blog to help customers understand some topics in the computer and internet world. 

Computer-Repair

Data recovery is the retrieval of inaccessible or contaminated data from media that has been damaged in some way.

With data storage devices such as hard drives, USB flash drives, etc. all becoming larger and capable of storing large gigabytes and terabytes of data.  Data recovery is important since you could lose a lot of information at once.

There can be several causes of data loss.

Data loss causes

Accidental deletion of a file or folder

Depending on the file system, each OS acts differently to delete a file. For Windows FAT file system the OS marks file directory entries as unused and destroys file allocation information (except beginning of file), for NTFS – just marks file entry as unused, deletes record from directory and marks disk space as unused; for most Linux/Unix file systems it destroys file descriptor (information about file location, file type, file size etc.) and sets disk as free.

The main purpose of each file deletion is to release storage space used by the file for a new file. Storage space is not wiped immediately (for performance reasons) making actual file data remain on a disk until this storage space is reused to store a new file.

  • File system format

File system format can be started by mistake, for example, by specifying a wrong disk partition or unclear actions as to storage handling (e.g. NAS devices usually format internal storage after attempt to re-configure RAID).

Format procedure creates empty file system structures on the storage and overwrites any information below. If file system types coincide, it destroys existing file system structures by overwriting them with the new ones; if file system types differ – the structures are written to different locations and may destroy user data.

  • Logical damage of a file system

This kind of failure may occur due to power loss or hardware failures. Sometimes logical damages are also caused by software failures. Modern file systems have a high level of protection against file system logical damages, nevertheless, useless against hardware or software malfunctions.

Even small piece of wrong data written to a wrong location on the storage may destroy file system structures, break file system object links and make file system non-readable.

  • Loss of information about partition

This kind of failure may occur due to different reasons, including failed ‘fdisk’operation or user errors that usually results in loss of information about partition location and size.

  • Storage failure

If you detect any physical problems on the storage (e.g. storage doesn’t start, makes unusual noises, overheats much, has problems to read data etc.),

Data loss can occur from unexpected incidences including national tragedies such as floods and earthquakes.

Often power failure can cause loss of data from hard drives. Sudden power surges can also cause a lot of damage to a computer’s hard drive.

Successful Data recovery depend much on the actual cause of data loss and further user’s actions. To get maximum data recovery results it’s strongly recommended to stop any write access to the storage and bring the storage device to Computer Physicians immediately.

Data loss caused by file deletion
Any deleted file remains on the storage until the storage space is re-used by other data. After file deletion OS may re-use disk space anytime to store a new file. Thus, even minor write to the storage may cause permanent data loss. Internet browsers may be involved in overwriting of deleted files as well by saving cache or cookies to the storage. If you install the software to the same drive, your data is also under the risk of overwriting.

Another factor that influences data recovery chances after file deletion is file deletion algorithm dependent on the file system. For Windows NTFS file system recovery chances are quite high, because if file descriptor remains on the disk, the software may easily take all required information about the file. Unlike NTFS, BSD UFS file system destroys information about file start, location and size permanently and together with high degree of file fragmentation typical of this file system leaves very slim chances for successful data recover.

Other file systems (like FAT) feature average chances for data recovery. Here only part of information is destroyed (like information about file fragments), but information about file name, start and size still remains on disk. Heuristic algorithms still allow to ‘guess’ file fragments and recover good files. Please keep in mind, that due to lack of real information about allocation of file fragments any data recovery software may fail to detect real file position, especially if several fragmented files were deleted close to the same location on the storage.

It’s not recommended to take any actions by yourself, since doing so may cause the data to be more difficult or impossible to retrieve.

You will need to bring your storage device that contains the data (computer, USB flash drive, external hard drive, floppy, etc.) to Computer Physicians to examine and determine if the data be retrieved.
