CISC VS RISC computers (all details)

By
CISC Introduction            The term "CISC" (complex instruction set computer or computing) refers to computers designed with a full set of computer instructions that were intended to provide needed capabilities in the most efficient way. Intel's   Pentium   microprocessors are CISC microprocessors. CISC is a   processor design   where single   instructions   can execute several low-level operations (such as a load from   memory , an arithmetic   operation , and a   memory store ) or are capable of multi-step operations or   addressing modes   within single instructions. The primary goal of CISC architecture is to complete a task in as few lines of assembly as possible. This is achieved by building processor hardware that is capable of understanding & executing a series of operations, this is where our CISC architecture introduced. The CISC approach attempts to minimize the number of instructions per program, sacrificing

DHCP principle , DHCP server and client communication process

By
1. Explain with principle: the DHCP server and client communication process DHCP stands for Dynamic Host Configuration Protocol. It handles the automatic assignment of IP addresses and other configuration settings for devices on your network. DHCP automates Network and Sharing Center in your control panel. This is especially good for people who have laptops, aren't hooked up to the Internet all the time and often move from place to place with their portable devices. They can simply get a new IP address as needed without having to do it manually. DHCP is designed to make the assignment of IP addresses and other network configuration information faster and easier. DHCP is a protocol that uses Level 4 on the OSI model. It communicates using User Datagram Protocol (UDP) datagrams through UDP Port 68. DHCP works with most current and past Windows clients, and also Linux, Macintosh, and many network-capable printers. DHCP is desi

Recommendation System literature review | Building a recommendation system

By
People have always relied on the recommendations from their peers or the advice of experts to support their decision making. Amazon.com has been using collaborative filtering for a decade to recommend products to their customers, and Netflix valued improvements to the recommender technology underlying their movie rental service at $1M via the widely published Netflix Prize [6]. Research on recommender algorithms garnered significant attention in 2006 when Netflix launched the Netflix Prize to improve the state of movie recommendation. The objective of this competition was to build a recommender algorithm that could beat their internal CineMatch algorithm in offline tests by 10%. It sparked a flurry of activity, both in academia and amongst hobbyists. The $1 M prize demonstrates the value that vendors place on accurate recommendations [8]. Recommender Systems provide the users with the suggestions of information that may be useful to the users to make their decisions on various sit

How to Become a Hacker
---------------------------------
1. Learn TCP/IP, Basic Information gathering,Proxies, Socks, SSL, VPN, VPS, RDP, FTP,POP3,SMTP, Telnet, SSH.
2. Learn Linux, Unix, Windows - You can do this using vmware or any virtual desktop utility.
3. Learn a programming language that's compatible with all OS - Perl, Python, C .
4. Learn HTML, PHP, Javascript, ASP, XML, SQL,XSS, SQLI, RFI, LFI
5. Learn Reverse engineering and crack some programs for serials easy ones like mirc, winzip, winrar or old games.
6. Code a fuzzer for common protocols - ftp,pop3, 80, 8080 - Pick some free software like ftp server, mail server, apache or iis webserver or a webserver all-in-one pack, or teamspeak, ventrilo, mumble.
7. Code a tool that uses grep to sort out unique code in source codes.
8. Make a custom IPtable, IPsec firewall that blocks all incoming traffic and out going traffic and add filters to accept certain ports that your software or scripts use.
9. Pick a kernel in linux or unix, also pick a Microsoft OS version lets say Winxp pro sp2 put them on the virtual desktops (vmware) and find and code a new local exploit in those versions, then install a Apache webserver on the Linux/Unix and a IIS webserver on the winxp pro and attempt to find and code a new local reverse_tcp_shell exploit.
10. Learn Cisco Router and Switch configuration and setup.
11. Learn Checkpoint Setup and Config
12. Learn Wifi scanning, cracking, sniffing.
13. Pick a person in you phonebook for the area code you live in or city then ring the person on a anonymous line like skype or a payphone or a carded sim and attempt to social engineer the person for his name, address, data of birth, city born, country born, ISP connected with, Phone company connected with, What bank he/she uses and anything else you can get. Then Attempt to ring using a spoof caller ID software with the person's phone number - call the ISP and try reset the password to his/her internet connection/ webmail, get access to bank account or ask them to send out a new *** to a new address (drop) with a new pin, reset of phone company passwords.
14. Use your information gathering skills to get all the information off a website like a shop then use the spoof callerID software or hack your phone to show a new number of the Webserver's Tech Support number then ring the shop owner and try get the shop site password.
15. Do the same thing but attempt to use a web attack against a site or shop to gain admin access.
16. Once got access upload a shell and attempt to exploit the server to gain root using a exploit you coded not someone else s exploit.
17. Make your own Linux Distro
18. Use your own Linux Distro or use a vanilla Linux gnome (not kde) keep it with not much graphics so you can learn how to depend on the terminal and start from scratch install applications that you will only need for a blackbox (Security test box), make folders for fuzzers, exploits, scanners..etc Then load them up with your own scripts and other tools ( By this stage you shouldn't need to depend on other peoples scripts).
19. Learn macosx and attempt to gain access to a Macosx box whether it be your own or someones else s.
20. Create a secure home network and secure your own systems with your own Security policies
and firewall settings.All this isn't a over night learning it will take a nice 3 - 4 years to learn a bit of this 5+ years to learn most of it and even then you may need time to keep learn as IT keeps changing everyday.
