Computer Security



Computer security 

Today  every one use Computer,and save Important Data Save,But You Do not know your not Safe .So How Safe Our Data.and 


A. What is computer security?

Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as "intruders") from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.

B. Why should I care about computer security?

We use computers for everything from banking and investing to shopping and communicating with others through email or chat programs.  Although you may not consider your communications "top secret," you probably do not want strangers reading your email, using your computer to attack other systems, sending forged email from your computer, or examining personal information stored on your computer (such as financial statements).

C. Who would want to break into my computer at home?

Intruders (also referred to as hackers, attackers, or crackers) may not care about your identity. Often they want to gain control of your computer so they can use it to launch attacks on other computer systems.
Having control of your computer gives them the ability to hide their true location as they launch attacks, often against high-profile computer systems such as government or financial systems. Even if you have a computer connected to the Internet only to play the latest games or to send email to friends and family, your computer may be a target.
Intruders may be able to watch all your actions on the computer, or cause damage to your computer by reformatting your hard drive or changing your data.

D. How easy is it to break into my computer?

Unfortunately, intruders are always discovering new vulnerabilities (informally called "holes") to exploit in computer software. The complexity of software makes it increasingly difficult to thoroughly test the security of computer systems.
When holes are discovered, computer vendors will usually develop patches to address the problem(s). However, it is up to you, the user, to obtain and install the patches, or correctly configure the software to operate more securely. Most of the incident reports of computer break-ins received at the CERT/CC could have been prevented if system administrators and users kept their computers up-to-date with patches and security fixes.
Also, some software applications have default settings that allow other users to access your computer unless you change the settings to be more secure. Examples include chat programs that let outsiders execute commands on your computer or web browsers that could allow someone to place harmful programs on your computer that run when you click on them.

Tech Purchase Decision Making

  Research Methods for Finding Reliable Product Reviews Start with professional tech review sites like TechRadar, GSMArena, and The Verge for comprehensive tech product analysis. These platforms maintain editorial standards and often conduct hands-on testing before publishing reviews. YouTube channels from established tech reviewers offer visual unboxing videos and real-world usage demonstrations that reveal details traditional written reviews might miss. Cross-reference multiple sources to get a balanced perspective. Reddit communities like r/Android, r/technology, and product-specific subreddits provide unfiltered user experiences. Amazon verified purchase reviews help identify common issues, but focus on detailed reviews rather than single-sentence ratings. Check manufacturer forums and official support pages to understand known issues and firmware update histories. Professional review aggregators like Metacritic compile scores from multiple sources, giving you a consolidated vi...

OSI MODEL (Open Systems Interconnection model )

To Day I Explain OSI MODEL,   Open Systems Interconnection model  ( OSI ) is a conceptual model that characterizes and standardizes the internal functions of a communication system by partitioning it into  abstraction  layers. The model is a product of the Open Systems Interconnection project at the International Organization for Standardization (ISO), maintained by the identification ISO/IEC 7498-1. The model groups communication functions into seven logical layers. A layer serves the layer above it and is served by the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.  The Below Shown Diagram is helpful to understand the OSI seven Layer Model. OSI MODEL EXPLANATION Th...
