Quick Introduction of Computer Files

February 24, 2021

We hear about files. Here is an explanation of the computer file.

Computer files are so-called because they bear a nodding relation to the old-fashioned manila files people once used to store bits of paper. Such files had tab markers with headings such as “Laundry Bills, 2008-2009,” allowing a primitive form of random access. For the moment, you can think of a computer file simply as a place for storing data and programs on your disk. Disk files also have tab markers known as filenames. Groups of files are stored in directories, which also have names. Both you and Unix use these directories and filenames when locating a file and accessing its contents.

A major service offered by Unix and most other operating systems is handling files by name. You usually do not need to be concerned with the physical location or structure of a file-Unix keeps track of these boring details. Your accounts payable data may reside on cylinder 87 starting at sector 102, and it may even move about during processing. All you need to know is the directory name,/usr/payables or whatever, and the file-name, say, ac. payable.

You or your application program may want to access a data file to examine or update its contents. Data or text files normally contain visible, printable characters encoded in ASCII format. You will meet commands that will display or print the contents of a text file by reading a sequence of characters from the disk. There are yet more commands that allow you to write to the disk in order to create and modify text files. You can also copy and rename files, or append one file to another. You can, dare I mention it, all too easily erase (or kill) files.

Multiuser systems need to offer safeguards to prevent users from reading and/or erasing other users’ files without due authority. Unix has an elaborate scheme of file ownerships and permissions whereby users and groups of users can protect their files. Each file in the system carries read, write and execute permissions that dictate who can do what with a file.

Binary files, unlike text files, which are easily readable by most humans, contain program code in a form understood only by your CPU. Although some groups of characters in binary code may coincide with ASCII characters, printing or displaying a binary file will give you gibberish and may even lock up your printer or terminal.

If you want to run a program, Unix needs to locate it by name. When you enter the command date, for example, Unix looks for a program file called date.

How Is Spam Affecting Your Day?

July 20, 2020

I was really at a loss for words today;

960 emails !! 960 unwanted emails.

I shouldn’t say they were ALL unwanted. The three that I wanted to read were in there somewhere; I just had to look very hard for them.

Spam or UCM is becoming a bigger and bigger problem every day. As we get closer to the holiday season the amount of spam will grow even more.

I received an interesting email in the batch today. It was so obvious that it was a spam that it wasn’t funny. The thing that got me the most was they sent it to the wrong email address !! It was full of other addresses that I know were harvested off a message board.

With the new anti-spam law that will be signed by the end of the year, the amount of unwanted junk mail will be staggering. It is estimated that over 45% of the email people receive is spam.

My personal amount averages 450 a DAY!

So what does this mean for you? Your email box will be blasted with unwanted mail as long as the sender follows a few simple rules. 1) They must give a full header. This means that the sender has to clearly identify themselves 2) They must give you a real line to be removed from their mailing list.

Be that as it may, it will not stop your hardcore senders from moving to offshore providers to run circles around the laws.

Many ISP services already have spam filters in place to stop the flood of email going to your inbox. The problem with them is that they block the mail you want as well. You still have to wade through it all to get what you want to send to your inbox.

Spam will be with us as long as email address survives. The problem will really never go away as long as you have to keep posting your address to get the information you want from the internet and the crawlers keep harvesting those names to sell. New laws will only be effective until the next spammer figures out yet another way to get around the system.

In short; the best defense against spam is a good offense. Learn to use the tools available. By blocking as much junk email as we can will we be able to maybe put an end to it.

Or at least really slow it down.

Do you know how DATA lost from your computer?

July 7, 2020

More than 95% of the people and businesses I spoke to experienced data loss. However, the sad fact is that most businesses are not very ready and do not understand the serious risk of data loss.

Do you have an accident plan?

The information you store on your computer can be lost in many ways. Many people are unaware of the various ways in which their data can be safely stored.

First, there are obvious ways.

Physical damage to a computer, such as a fire or water damage, is one surefire way to lose all information on your computer. Although insurance can cover physical damage to your machine (s) and you can replace the correct hardware, no insurance policy can recover your data.

Another common way for individuals to lose the data they have worked hard to build is THEFT. As with many computer disasters, insurance can cover physical hardware, but there is no policy to store the information stored on your hard drive and other physical media.

If you don’t have a backup solution, your data is at risk every day.

There are many other things that can cause partial or complete data loss. Other common events are:

Data corruption (failed CRC or MD5 checks),

Hard drive failure (more hard disk is getting closer to MTBF, or “mean time between disk” rated at the factory)

It is not unusual for a machine to reboot after replacing critical system files, such as a Windows OS package or a driver update application.

Human error – simply deleting a file or directory occurs more often than you think. Not to mention the “non-emergency” cancellation by an unhappy employee.

Viruses and worms – Although protection is easily available and widely used for these digital pests, data loss associated with them is still widespread.

These are just a few of the potential threats that can hit a computer that is not backed up at the time.

Now ask yourself, “What can I do?” You may ask. In fact, there is one simple solution for all your data integrity needs: external backup information.

Backups may be used to perform separate tape drives or other removable media, Offsite data provides a very clear, easy-to-use, and secure way to keep files in a secure location. They are safe (remember, if your office building fires a fire, your workplace will not only destroy the data but also prevent your tape from using expensive firewalls.

Data backup is easy to manage and protect your data offline in the most secure, economical way possible. If you are thinking about implementing a data backup for your company or personal computer, do yourself a favor and consider using a secure backup service. This is the simplest and most effective disaster recovery.

Your DATA is your life. What you are waiting for.

How to choose an Identity Theft protection plan

February 13, 2020

One of the major criminal activities that become more and more present in our lives is identity theft. This is partly because we live in an era when technology plays an important role and that can ease access to our personal information.

There are a lot of companies that have identity theft protection plans for you. However, not all of them are working properly and you should be able to make the difference if you want the best results when it comes to preventing identity theft.

There are a lot of protection plans that cost as low as $10 a month but unfortunately, in many cases, they do not work. You should do a little research in order to be able to separate the working ones from the non-working ones. There are slight differences that can make the difference in many cases.

For example, a credit freeze is similar to a credit alert. However, if you are subject to identity theft, you would want your credit frozen instead of alerting you.

Another important thing that should be provided by identity theft protection plans is identity recovery. If you are subject to such a crime, you should be helped with recovering your identity. This is for sure because in many cases it can be a very difficult task and you will need some help with that.

Unfortunately, many companies offering identity theft protection plans have a strong marketing message which is not backed up by anything. This is a reality and you should be aware of it. For example, they might promise a lot of money in the unfortunate case that you have your identity stolen.

However, the fine print from the bottom of the contract says otherwise so you will not get anything from them. Also, the best-marketed companies in this domain of identity theft protection are not necessarily the best one on the market.

A very common mistake made by many people is to believe that purchasing such identity theft protection plans will help them avoid identity theft completely. This is not true because you will have to avoid identity theft yourself by taking some safety measures in order to minimize the risk of identity theft. You should expose your personal information as little as possible especially online and you should be careful at your mailbox and empty it every day.

In conclusion, if you will choose a good and appropriate plan for you, the chances of having your identity stolen decrease. However, you should be aware that in many cases you will have to take some measures yourself.
