Computers have evolved over the years from the static mainframe computers to the portable modern computers which we use today. But do you know exactly about computers? Let me introduce you the components of the Computer.

The main components that make up the computers are:

Memory: enables computers to store data and programs.

Mass storage device: this is commonly referred to as the hard disk.

Input devices: such as the computer keyboard and mouse.

Output devices: such as the screen.

CPU: is the heart of the computer and is responsible for all executions.

Computers affect our lives a lot, they play many important roles, helping to promote communication and interaction with each other as well as providing users a way to shop, play games and have access to education. Besides, computers provide a convenient way to create and store valuable information along with media and files, making them particularly useful for businesses.

Communication

They enable you to form strong friendships with people you will never meet, even though you don’t know the name of your next door neighbor. If you work in another city and don’t have enough time or money to go home, you can rely on computers. With computers, you can meet with your lovers via video, and it only needs a webcam.

Schoolwork

In college, you need a computer for pretty much everything. You can enroll for classes via computer. You can apply for student loans, grants, scholarships. In most classes you must have a computer for your assignments. You can look up helpful information, and print it out and use as a studying tool.

Company

From the early mainframe servers to iPads, computers have become workplace mainstays. They play a role in how businesses communicate internally and externally, manage their employees, run their production lines and track their customers. Businesses have been able to justify their computer investments because of the positive effects on profitability, strategic and operational flexibility, employee productivity and organizational learning.

Computers in writing

One can write more effectively by means of a computer. A computer allows the user to create documents, edit, print, and store them so that they can be retrieved later. There are tools like spelling and grammar checker, thesaurus and dictionary, installed in the computer. So, it takes less time to proofread a written document. Also, there is no need to open up a dictionary book to look for meanings of words. If there is a need for reorganizing the sentences or paragraphs, one can cut and paste and make the necessary changes.

Computers make the world we live easier.

Little USB Flash Drives Now a Big Security Threat

In our daily life, we usually like to use USB flash drives to deliver or storage data. It’s so convenient and small that it’s become a fashionable accessory. But do you know the little USB now change into a big security threat?

What is USB flash drive?

A USB flash drive, also known under a variety of other names, is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc. Most weigh less than 30 grams (1.1 oz). As of January 2013, drives of up to 512 gigabytes (GB) were available.

Hundreds of millions of thumb drives (aka flash drives) are sold every year. In addition to backing up data, these little devices are extremely useful for sharing large files between computers. It’s more convenient and secure than using an Internet file sharing service. However, there is also security threat from the USB flash drive.

As a report suggests, almost 32 percent of the companies around the world experience an attack of virus via USB thumb drive. Data security experts’ rate USB flash drives quite high as the source of data leakage and responsible for spreading harmful viruses. Knowing the fact, USB flash drives are still the most vastly used portable data storing device around the world.

What security risks are associated with USB drives?

1. One option is for attackers to use your USB drive to infect other computers.

An attacker might infect a computer with malicious code, or malware, which can detect when a USB drive is plugged into a computer. The malware then downloads malicious code onto the drive. When the USB drive is plugged into another computer, the malware infects that computer.

2. Attackers may also use their USB drives to steal information directly from a computer.

If an attacker can physically access a computer, he or she can download sensitive information directly onto a USB drive. Even computers that have been turned off may be vulnerable, because a computer’s memory is still active for several minutes without power. If an attacker can plug a USB drive into the computer during that time, he or she can quickly reboot the system from the USB drive.

3. USB drives missing

If a lost or stolen USB drive contains sensitive personal information that’s not encrypted or secure — and a lot of data on USB devices isn’t, according to security experts — it opens the door for identity theft and other types of cyber crime.

In case of the security threat, it’s time to protect your USB. Protecting USB devices doesn’t have to take a lot of time or money. In many cases, all it takes is some good old-fashioned common sense. Here are suggestions for what you can do to minimize the risk that comes with using USB drives:

1. Use encryption. 

If you absolutely must put sensitive information on a USB device, encrypt it first. So it can’t be viewed without being decoded first.

2. Keep home, office devices separate. 

Don’t use the same flash drives for home and work to avoid accidentally introducing a virus you picked up from an infected device into your company’s office network.

3. Use and maintain security software, and keep all software up to date 

Use a firewall, anti-virus software, and anti-spyware software to make your computer less vulnerable to attacks, and make sure to keep the virus definitions current. Also, keep the software on your computer up to date by applying any necessary patches

 

 

Is It an Old Domain Name Better?

There are many kinds of people on internet. Some buy domain name to use. A domain name is your own unique identity and always will be as long as you continue to use that particular name. You are required to consider many factors before purchasing a domain name

Domain name description

A domain name is a unique name that identifies an internet resource such as a website. It is an identification string that defines a realm of administrative autonomy, authority or control on the Internet. Domain names are formed by the rules of the Domain Name System (DNS). Any name registered in the DNS is a domain name. The functional description of domain names is presented in the Domain Name System article. Broader usage and industry aspects are captured here.

There has long been much debate about whether older domain names rank higher simply by age or more by having more chance of being indexed, linked and found, but even after Google’s most recent changes, the general consensus still appears to be that an older domain name can help with your search engine ranking.

If you are considering buying a domain name or you want to put your domain name up for sale, you should get an idea of how much it is worth.

How to Value a Domain Name

1. The length of the domain—the shorter the domain is, the more it will cost.

2. How many words are in the domain—similar to the length, domains with very few words cost the most, so a one word domain is the most valuable.

3. How long has the domain been live—Domains that have been around for a long time rank better in search engines, and so this increases their value.

4. Spelling and use of the domain word(s)—a domain that is a common word (or words) and has a common spelling that is easy to type and remember is going to cost more.

5. Domain extension—the best extension for a domain is the .com extension. This is because it’s what most browsers default to, and most users assume that is the name of the domain.

Many people say that an older domain name can help with your search engine ranking. So let’s have a look at two factors may affect whether or not you buy an older domain name:

1. Quicker results

Many experts now suggest that it is far more difficult for new websites to achieve decent rankings on Google. This may or may not have a scientific reason, but with more domains than ever an older domain with an existing ranking is easier to push up the list from lower down than jump straight in. In addition, an older domain is more likely to have more Google trust and organically good rankings for keywords that can quickly be tapped into.

2. Link value

Google’s new focus on the need for relevant and quality links has made this factor more important. A domain name with a batch of authoritative links to sites relevant to the content you want to push has great value in the Google-sphere. Equally, quality is the important measure as quantity may actually have a negative impact if the links are deemed irrelevant to the content on the site.

The success of your activity on internet is mostly granted by the website you are using. The more users connect to your website, the more it will be considered on the Page Rank. So, get an old domain name is good for your success.
