Internal and External Hard Drives
All around the world, on laptops, computers, phones, and mp3 players, electronic devices are being used to perform everyday functions. We can pull up saved passwords, applications, and saved files in a matter of seconds. But how exactly are these files saved onto these devices? What units are used to represent the amount of data being saved? How exactly do computers save documents and applications that can be sent from one computer to another?
What units are used to represent the amount of data being saved? The data used in a saved document are all measured units. “The storage capacity is expressed in terms of Bytes.” (Simply Easy Learning) After a bit, comes a nibble, which is two bits. After a nibble, is a byte, which is eight bits. These small units are not used very often in everyday life because most documents use millions of these. The bigger units are as follows;
UNITS BYTES
Kilobyte (KB) 1,024
Megabyte (MB) 1,024 KB 1,000,000*
Gigabyte (GB) 1,024 MB 1,000,000,000*
Terabyte (TB) 1,024 GB 1,000,000,000,000*
Petabyte (PB) 1,024 TB 1,000,000,000,000,000*
”A computer word like a byte is a group of fixed number of bits processed as a unit which varies from computer to computer but is fixed for each computer. The length of a computer word is called word-size or word length and it may be as small as 8 bits or may be as long as 96 bits. A computer stores the information in the form of the computer words.” (Simply Easy Learning)
How exactly are these files saved onto these devices? Every computer has an internal hard drive and a processor. What the processor is basically the eyes of the computer. It reads and processes a code of billions of 1’s and 0’s known as binary. This is also what is...

Hard Disk Drive (HDD) - Hard drives can store very large amounts of data ranging from 200GB – 1TB. A hard drive is made up of a magnetic disk that consists of a number of platters/disks that are coated in a magnetic material that rotate at 7200 RPM. The data is encoded into bits and written into the disks as a series of changes in the direction of the magnetic pull, and then the data is read by detecting the changes in direction on the
It’s understandable that the NSA must store information from people that are potential threats as it allows them to track and monitor their activities and interactions. In spite of this, storing information from everyone that the NSA has ever accessed is simply prompting a security breach to occur. So, for those who say, “if you have nothing to hide then you have nothing to worry about” should consider the idea of a potential security breach since this could be the one thing they will have to worry about. An article published on nativist.org explains the possibility of information being leaked and used against individuals. The article then goes on to explain that “hackers could potentially gain access to the databases of the government surveillance programs”. Even though it is highly unlikely for this to happen as the NSA states that everyone’s information is “safely secured using our custom database software called Cloudbase, which has fine-grained security to control access down to the cell level” stated by the Domestic Surveillance Directorate, there is still that slim possibility it can still happen. Someone should not need to sacrifice all their privacy for safety to the NSA as it could be the one thing that ruins someone’s life. Aside from that, if the NSA stored less information there would be less interest in breaching the system as it would attract less
It can be very expensive; costing hundreds of dollars for each stolen record. It’s challenging to prevent when hackers constantly update and change their patterns faster than the software designed to stop them is updated. Adding to that, users who try to circumvent security policies they find annoying or restrictive [3]. Another point of possible breach is employees accessing the network via personal devices (tablet, phone, usb) [4], poor network access passwords, and outdated server software. Even web cookies have the potential to provide access to private information [5]. There is no shortage of vulnerabilities that exist within any network and now some of the securities that are in place have been under discussion on just how “secure” they should be. Last year the terrorist attack in San Bernardino not only caught headlines because of the attack, but also because shortly thereafter there was a standoff between the FBI and Apple due to Apple’s refusal to crack the terrorists phone for the FBI. Apple stated that, “Up to this point, we have done everything that is both within our power and within the law to help them.” It continued, “But now the U.S. government has asked us for something we simply do not have, and something we consider too dangerous to create. They have asked us to build a backdoor to the iPhone.” [6]. Since the FBI vs Apple case, regarding the complexity of the encryption Apples uses for its devices, encryption backdoors have been a hot topic. Apple argues that having one defeats the purpose of the encryption, making it easier to access and exploit data [7(a)]. Having encryption and Firewalls bring a peace of mind but vigilance, constant upkeep, and caution on the users end are also required for network security. Backing up data, avoiding a single point of failure, and making sure data is only put where it needs to be are a few extra precautions to keeping your network secure
We now accept the sharing and digital storage of our personal information as a necessary evil. We continue to incorporate, into our lives, technology that uses this data. Microsoft and Google are envisioning and developing ways to commercialize the use of even more of our stored personal information.

The personal connection Americans have with their phones, tablets, and computers; and the rising popularity of online shopping and social websites due to the massive influence the social media has on Americans, it is clear why this generation is called the Information Age, also known as Digital Age. With the Internet being a huge part of our lives, more and more personal data is being made available, because of our ever-increasing dependence and use of the Internet on our phones, tablets, and computers. Some corporations such as Google, Amazon, and Facebook; governments, and other third parties have been tracking our internet use and acquiring data in order to provide personalized services and advertisements for consumers. Many American such as Nicholas Carr who wrote the article “Tracking Is an Assault on Liberty, With Real Dangers,” Anil Dagar who wrote the article “Internet, Economy and Privacy,” and Grace Nasri who wrote the article “Why Consumers are Increasingly Willing to Trade Data for Personalization,” believe that the continuing loss of personal privacy may lead us as a society to devalue the concept of privacy and see privacy as outdated and unimportant. Privacy is dead and corporations, governments, and third parties murdered it for their personal gain not for the interest of the public as they claim. There are more disadvantages than advantages on letting corporations, governments, and third parties track and acquire data to personalized services and advertisements for us.
One important reason that advancements in technology are bad is Personal identifying information can be found by anyone who has a computer. People’s personal information, like address and medical history can be found, because almost everything is online. ID theft is a growing problem in the United States. “The scope of ID theft has grown so quickly that it now takes up a substantial and growing portion of law enforcement resources.” This means that ID theft is becoming a big problem. Once your ID is stolen it can be very difficult to get back what you lost.“Though the costs of getting your money back have declined, victims aren't getting back all of what was taken”. This means that when people’s things get stolen over the internet, they may not get everything back that was taken.Technology is so advances people’s personal information can be accessed by anyone with a laptop, and that is something that needs to be changed.

The computer that we use in our homes and places of business usually consists of a box containing the computer, a mouse, a couple of disks with drivers, a monitor for output and a keyboard for input. We may connect the computer to any number of local or remote peripherals of other computers, but here is the foundation of the computer. It is here that everything starts, and here is where all of the innovations and ideas of the present day have been started. For the moment let's assume that sufficient processing takes place inside the computer, and look at how things get in and out.

Technology is great in so many ways. It has provided us with more communication access, access to knowledge at our finger tips, and so much more. Technology has overall made life easier, but maybe too easy, and has made things a lot less private. This results in us having to be extra careful with security on the internet. Internet security is important to protect our privacy, protect us from fraud, and from viruses that could destroy a piece of our technology. Internet privacy and security may be different but share a responsibility, but it is up to us to take personal responsibility to protect ourselves on the internet. We should pick unique, carful passwords, and never share this sensitive information, and encrypt our data when online.
There are four types of memory. These are the RAM, ROM, EEPROM and the Bootstrap loader. The RAM, also known as Random Access Memory, is the temporary space where the processor places the data while it is being used. This allows the computer to find the information that is being requested quickly without having to search the hard drive space. Once the information has been processed, and stored onto a permanent storage device, it is cleared out of the RAM. The RAM also houses the operating system while in
Now my paper is about synchronizing the data available in the USB flash drive with the PC or laptop. This can be achieved by implementing the effect of few modules available and also by modifying the design of the USB flash drive. We shall now discuss in detail
