Wireless standards

There are a number of standards that have been developed to ensure that the wireless devices so they can communicate. They specify the RF spectrum that is used in data organization’s which is responsible for the creation of wireless technical standards is the Institute of Electrical and Electronics Engineers. The IEEE 802.11 standard governs the WLAN environment and there are amendments to the IEEE 802.11 standards of wireless communications. The wireless standards for LANs use the 2.4 GHz and z GHz frequency bands which collectively these technologies are referred to as the WI-FI. There is another organization known as the WI-FI Alliance that is responsible for testing wireless LAN devices from different manufacturers. The WI-FI logo on a device means that the equipment meets standards and should be operated with other devices used by the same standards. The wireless standards are constantly improving the connectivity and speed of the WI-FI networks and it is important to be aware of

Operators in C language

Image
Operators One of the most important features of C is that it has a very rich set of built in operators including arithmetic, relational, logical, and bitwise operators. An operator can be any symbol like + - * / that specifies what operation need to be performed on the data. For ex: + indicates addition operation * indicates multiplication operation Operand VS Operator • An operand can be a constant or a variable. • An expression is a combination of operands and operators that reduces to a single value. For example: Consider the following expression: a+ b Here 'a' and 'b' are operand while 't' is an operator Operators & Expression are 1) Arithmetic Operators and Expressions 2) Assignment and Compound Assignment Operators 3) Increment and Decrement Operators 4) Relational Operators and Expressions 5) Logical Operators and Expressions 6) Bitwise Operators and Expressions Arithmetic Operators An arithmetic operator performs mathematical operators such

Data types in C language

Image
Data Type Datatype is an entity that defines a set of values and a set of operations that can be applied on those values. It determines the type and size of data associated with variables. Data type in C language Primary data types Primary data types are also known as the fundamental data types because they are pre-defined or they already exist in the C language. All C compilers support four fundamental data types, namely int, char, float, and void. Derived data types Derived data types are derived from the primitive or fundamental data types. There are mainly 3 types of derived data types in C There are mainly 3 types of derived data types in C Array Function Pointer User defined data types The data types that are defined by the user are called the user-defined derived data type. For this a special keyword is needed such as typedef, enum, struct, union. The C program consists of the following types of UDT: Structures Union Typedef Enum

PentesterLab

PentesterLab PentesterLab is an easy and great way to learn how to do penetration testing. It is completely beginner friendly and you do need to pay for it but it is completely worth it. Go check it out with this link https://pentersterlab.com/. Hacking the box HTTB allows you to test your penetration testing skills. This site is very good for grasping various security concepts and also acts like a starter kit to crack OSCP. Hacking the box is completely free . Go check it out with this link https://www.hackthebox.eu/. PortSwigger It can potentially be used for some high severity exploits. This makes it an ideal first topic for beginners and essential knowledge even for more experienced users and it is free . I can’t find the link to it but I will keep you posted and update the link when I find it.

Gene Editing

Image
Gene Editing A genetic engineering do in fact poses some ricks but unfortunately the scientists do not simply know enough to identify them just yet but they believe a bad genes come from having Cross Contamination,Increased Weeduness,Gene Transfer to Wild or Weedy Relatives,Change in Herbicide Use Patterns,Squandering of Valuable Pest Susceptibility Genes,Poisoned Wildlife and the Creation of New or Worst Viruses. When bad genes are found/discovered that where gene editing can be especially beneficial. Bad genes are types of genes that cloud an organism or its offspring's health in jeopardy. The help of gene editing with those negation features can be changed. This might be a result of the organism’s behavior that may change or it just may acquire some whole new skills.

Packet Tracer notes

Cisco Packet Tracer notes The meaning behind a yellow circle means that there is a device/devices which are not connected properly. The meaning behind a red triangle means there is a device/devices that are not connected. A green triangle means the computers are connected and can talk to each other.
