IT - Research Paper Example Thus, it is advised by computer experts to keep a backup of the information and resources that are stored on computer systems. This paper will focus upon the various storage devices that can be used by computer users to keep a backup of their information and resources, and the differences between redundant and backup data storage and how systems fail and how can they be protected. Backup Media Various forms of backup media available to users include: optical storage methods such as writeable and re-writable CDs and DVDs, external and internal hard disks that can be mounted on the systems and flash memory systems such as pen drives, USB drives and memory cards. Information stored on optical drives can last for very long period of time if these drives are kept safely, secondly these drives are even available in write once only form. This is an advantage because the data that is stored on these drives cannot be replaced or over-written. These drives even come in re-writable form; this m eans that same drive can be used do over write if old information is no longer needed. These drives are easy to move from one pc to another, these drives can be used in several systems but one system can use it at a time. Another downside of optical drives is that the time taken by these drives to write data and store information on them is considerably high if compared to the time taken by flash drives and other forms of memory drives. Another form of backup media that can come in handy for computer users is installing a second hard drive internally or externally. The advantages of having a second hard disk are enormous. Firstly, the second hard disk can act as a backup for files stored on your system; this will come in handy if the files from the first hard disk are deleted. Another advantage of using an extra hard disk is that the process of backing up files in a second hard disk is faster as compared to backing up these files in an optical drive or a USB flash memory drive. Havi ng a second hard disk is even of advantage as the files and the resources that have been downloaded over time on the computer system can be safe and the users d not have to take the pain of downloading and saving these resources again. All the operations conducted in a computer system take place on the first hard disk or the primary hard disk, due to this continuous usage, the hard disk becomes old and starts wearing out and ultimately the user has to replace it. When two hard disks are involved in the process of running a computer system, the burden of running the computer system is shared and both the hard disks gain higher functional life time. Disadvantages associated with installing a second hard disk are few in number. Firstly, hard disks have to be dealt with extra care, misuse may easily damage or corrupt the hard disk and data loss may occur, secondly, if the drive is installed inside the system, moving the drive to another system might become difficult and during the trans fer, the chances of damage are quite high. One of the best backup media designed to-date is USB flash memory drives/sticks. The advantages of using this media are: they are very small in size and can hold huge amount o information, they are easy to move and do not contain parts that might get corrupted if they are mishandled. These drives are even better than optical drives as they cannot be destroyed due to scratches and dust. Installing them is much easier than installing hard disks as they do not need

War Strategists - Essay Example Consequently, Jomini’s theory of strategy entirely relied on geometric considerations. He advocated concentrating alongside fractions of the enemy’s force before striking the critical objective. Significantly, Clausewitz and Jomini theories have immensely contributed to understanding today’s military profession1. Accordingly, the FM 3.0 represents a revolutionary departure from past theories. It has engaged in an operational of employing such principles as offensive, stability or civil support operations concurrently as part of an inter-reliant joint force to grab, retain and exploit the initiative, accepting practical risk thus generating opportunities for achieving decisive results. The FM 3.0 operations significantly initiated a comprehensive change in the army by capturing the solder’s experience over t numerous years of extensive combat. It therefore changed the army’s conceptualization of operations hence it adopted FSO as a central tenet of h ow it applies its capabilities. Consequently, the concept of FSO plays critical roles in the army. FM 3.0 reflects an inclusive understanding of the numerous impacts of myriad years of persistent conflict in army operations. It puts emphasizes on people over technology, hence focus on an initiative and responsibility at lower levels of command2. It is worth noting that, understanding the operational environment and the intriguing problems, requires a precise methodology that expands beyond the military decision making process. Currently, the operational environment has experienced an enormous emergency of hybrid threats hence profoundly increasing uncertainty in the operational environment. In response, it has called for the need of creating teams to work closely with joint interagency and multinational assets among modular forces. Additionally, working with host-nation partners, teamwork requires extensive personal cooperation instead of military command. Finally, the capability to transmit clear and concise messages to target audiences plays a critical role in delivering lethal combat work. Consequently, it calls for an appropriate strategy in order to ensure victorious success in FSO. In response, current research has revealed that, the FM 3.0 has adopted a peculiar strategy referred to as blitzkrieg war strategy. Additionally, the strategy has based its foundation on nine compressive principles for success in FSO3. The blitzkrieg strategy entails employment of lightning attacks, overwhelming the enemy with speed ad concentrated fire-force. Typically, blitzkrieg strategy largely relies on tanks, which combine with speed. Its basic principle entails bombardment of a weak point in the enemy defense followed by feints and thorough probes to find a breakthrough point, plus a follow-up encirclement to prevent flanking and capturing remaining forces. Accordingly, at the defeat of the enemy, a follow up force may hold the position, while the main force moves on qu ickly to the next target. Blitzkrieg strategy works entirely by shock and depends entirely the maneuver and surprise principles rather than wearing down the enemy by long bombardment or pitched battles. Consequently, it represents a typical cross-country technique for conquering large tracts of relatively defended land. In addition, it implies distracting a dispatched the enemy from dealing with your attacks4. Similarly, the FM 3.0 provides
