CASE STUDY 2

for me im agree  Romanian hacker charged with breaching NASA computers because  NASA is a little memory compared to modern home computers.and also hacker is a  contentious term used in computing for several types of person, the days when a team devoted to nothing other than protecting our identities and credit card information was more than sufficient security When  data banks were impenetrable, the government websites were unassailable and everything on our phones was ours alone as long as it was safe and sound in your pocket? That faraway time known as  June Here a look at the largest and most overt hacks of the last year.Late last year a mysterious virus was found in the computer system of an Iranian government nuclear power plant.Operation Payback was a series of hacks throughout 2010, starting with attacks on various organizations attempting.broke into the Senate’s website and posted some of the Senate’s internal data on a public site. Luckily, the data was reportedly not especially sensitive.In the last few months, Sony has been hacked 3 times with a grand total of around 100 million users’ personal information and credit card information compromised. The most recent intrusion cost them 93,000 Network accounts due to frustrated users turning off their services. At one point, the Network, the online interface central to the  3’s function, was down for almost two months.
BUCHAREST: A young Romanian has been charged with hacking into NASA computers and causing more than $1.5 million of damage for the US space agency, prosecutors have said.
Victor Faur, 26, from the western town of Arad, was also accused of breaking into the computers of the US navy and the Department of Energy between November 2005 and September 2006, a statement said on Tuesday.and also why he called White Hats have been tracking the progress as patiently as everyone else allowing the good fellows in the international banking community to move through the process of being the meticulous mechanics they are.

for me antivirus to Protict the unit in the PC so that we called to bi install the unit so that,
your unit very safe.Conficker a computer virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming , whereas viruses almost always corrupt or modify files on a targeted computer. a shared resource or network share is a device or piece of information on a computer that can be remotely accessed from another computer, typically via a local area network or an enterprise Intranet.

REFLICTION PRELIM TOPICS

for me im i have a lot to learn to this subject 
also im injoyed to lesining sir mark the way he talk and to expliane to us
what he talking a bout the topics
i wish i will passed to this subject
and i hope sir mark they have a lot a patince of some students sometimes dont have a inetiative.

DATA STRUCTURE PRELIM TOPIC

ARRAYS-Arrays are analogous to the mathematical concepts of vectors, matrices, and tensors. Indeed, arrays with one or two indices are often called vectors or matrices, respectively. Arrays are often used to implement tables, especially lookup tables; the word table is sometimes used as a synonym of array.

STACKS-A stack is a restricted data structure, because only a small number of operations are performed on it. The nature of the pop and push operations also means that stack elements have a natural order.


QUEVES-

LINKED LIST-

Linked lists are among the simplest and most common data structures. They can be used to implement several other common abstract data structures, including stacks, queues, associative arrays, and symbolic expressions, though it is not uncommon to implement the other data structures directly without using a list as the basis of implementation.

REFLECTION IN PRELIM TOPICS

To create own program and to run the data wich were when how to process the data. i wish to be passed to this subject

i well agree they when he teach to expliane

So that i have a lot to learn thise subject i wish sir mark they have a patience a student . because sometimes they have some of student don’t have a inichative.

1.booting-booting (also known as booting up) is a bootstrapping process that starts operating system when the user turns on a computer system. A boot sequence is the initial set of operations that the computer performs when power is switched on.

2.GUI-A graphical user interface (GUI) is a human-computer interface (i.e., a way for humans to interact with computers) that uses windows, icons and menus and which can be manipulated by a mouse (and often to a limited extent by a keyboard as well).

3.linux-Linux can be installed on a wide variety of computer hardware, ranging from mobile phones, tablet computers, routers and video game consoles, to desktop computers, mainframes and supercomputers. Linux is a leading server operating system, and runs the 10 fastest supercomputers in the world.

^{4.Macintosh OS-}The Macintosh user experience is credited with popularizing the graphical user interface. The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

5.MS-DOS-MS-DOS grew from a 1981 request by IBM for an operating system for its IBM PC range of personal computers. Microsoft quickly bought the rights to (Quick and Dirty Operating System), also known as 86-DOS, from Seattle Computer Products, and began work on modifying it to meet IBM's specification.

6.MULTITASKING-In computing, multitasking is a method where multiple tasks, also known as processes, share common processing resources such as a CPU. In the case of a computer with a single CPU, only one task is said to be running at any point in time, meaning that the CPU is actively executing instructions for that task.

7.NOS-National Occupational Standards (NOS) specify UK standards of performance that people are expected to achieve in their work, and the knowledge and skills they need to perform effectively.NOS can be used to support any and all human resource management and development activities, as shown in the developed for Skills for Justice to support the use of the NOS for Legal Advice.

8.OS-An operating system (OS) is software, consisting of programs and data, that runs on computers, manages computer hardware resources, and provides common services for execution of various application software. The operating system is the most important type of system software in a computer system. Without an operating system, a user cannot run an application program on their computer, unless the application program is self booting.

9.system software-System software is computer software designed to operate the computer hardware and to provide a platform for running application software.System software is computer software designed to operate the computer hardware and to provide a platform for running programs such as "Windows Update" for Windows or "Software Update".

10.application software-Application software is contrasted with system software and middleware, which manage and integrate a computer's capabilities, but typically do not directly apply them in the performance of tasks that benefit the user. The system software serves the application, which in turn serves the user.

11.UNIX-a UNIX system is and its associated trademark in trust for the industry. 

12.Utility programs-A program that supports using the computer, an application or a development environment. Also called "utilities," utility software is programmed like any other software, except that it plays a supporting role. Usually relatively small programs, they typically perform a limited number of tasks.Utility programs include file management (creating, moving and renaming folders, copying and deleting files), file search, comparing file contents as well as performing diagnostic routines to check the performance and current health of the hardware.

13.Windows-Windows Update is included in Control Panel. In the future, to check for updates (or if this webpage doesn’t open Windows Update automatically):
  Click the Start button, click All Programs, and then click Windows Update.

Microsoft Windows is a series of operating systems produced by Microsoft.

Microsoft introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical use

14.Windows CE-Windows CE (officially known as Windows Embedded Compact), is an edition of Windows that runs on minimalistic computers, like satellite navigation systems and some mobile phones. Windows Embedded Compact is based on its own dedicated kernel, dubbed Windows CE kernel. Microsoft licenses Windows CE to OEMs and device makers.

15.Windows mobile- is a mobile operating system developed by Microsoft that was used in smartphones and mobile devices, but by 2011 was rarely supplied on new phones. The last version is "Windows Mobile 6.5.5"; it is superseded by Windows Phone 7, which does not run Windows Mobile software.

*Differentiate

Mac OS vs Windows vs UNIX- Unix vs. Microsoft Windows

Microsoft Windows is widely regarded as the epitome of insecure platforms a platform fraught with innumerable security problems. Windows systems top the charts in perhaps every major vulnerability and incident list. In contrast, Unix systems are perceived to be considerably more secure.  
How Did Windows Become "So Insecure"?

I posed this question to a few people: technology experts, and non-technical users. I found that very few people had actually ever given this any serious thought. They "just knew" that Windows is "the most insecure platform." Those who were willing to think on-the-fly ascribed their beliefs to gut-feeling, perpetual digital disasters crashing down upon Windows (as experienced first-hand or as reported by the media), statistics (incidents and vulnerabilities published by respectable organizations), folklore, inherent (sometimes inexplicable) hatred of all things Microsoft, inherent affinity for Unix, etc. Some conjectures took Microsoft's monopoly into account, concluding that Microsoft "doesn't really care" about security, as they can afford not to, and still be successful.
