What is DSL Internet

DSL stands for Digital Subscriber line, it is technology where a DSL line is used to connect to the internet and transmit digital data through copper telephone lines. DSL is emerged as revolutionary and innovative technology solution in the 1980s and 1990s. In-depth discussion of DSL, Addressing connection, Types, Full form, and network topology is provided in this article.

DSL full form:


DSL stands for digital subscriber Line. This nomenclature is rooted in the technology fundamental function. The subscriber line is part of the name indicates that the technology is used on the individual lines of subscribers, typically ordinary telephone line that connect homes and business to the telephone company's  central office. 

There are three types of DSL:

  • ADSL: With asymmetric DSL, download rates are quicker. Data reception is quicker than data transmission. 20 Mbps for downloads and 1.4 Mbps for uploads are possible.
  • SDSL: Because symmetric DSL evenly divides the incoming and outgoing frequencies, the bitrates for uploads and downloads are equal.
  • VDSL: Very high speed digital subscriber line, an upgrade on their prior HDSL, VDSL connects to extremely high frequencies providing download speed of up to 52 Mbps and upload speed of up to 16 Mbps. VDSL2 can provide speed up to 1000 Mbps for both upload and download.
How does DSL operates?

DSL transmit data by using copper telephone lines higher frequency channels. Because of this strategy, phone and internet services can operates simultaneously on the same line without interfacing with one another. A DSL modem, which modulates and demodulates data signals, and a DSL cable, which connects the modem to the phone line, are the essential part of a DSL connection. User will always have a dedicated line for internet access due to this configuration.

Circuit switching techniques | Characteristics | Types | Advantages | Applications

Circuit switching is a network configuration operates almost the same way as the telephone system works. In this network configuration, two network endpoints are connected via a dedicated physical path for the duration of the dedicated connection.  Before communication to occur, there needs to be a complete end-to-end channel. Regular telephone service makes use of circuit switching. 

There are three phase of circuit switching which are as follows:

Circuit Establishment:

A dedicated physical route is established between the sender and the receiver. The path may include a number of intermediate switching centers.

Transfer of Data:

After the establishment or setup phase, data is transferred through the dedicated path.

Circuit Disconnect:

Once the data transfer is done, the circuit is disconnected from one of the ends. All the intermediate links are disconnected in this phase.

What is GDDR5x

GDDR5X

In 2016, a new version of GDDR5 was released. The GDDR5X was the name of this. But in the early going, it was limited to usage with certain Pascal-based GPUs from Nvidia. But as more and more people became aware of how it differed from the GDDR5, sales of it began to rise.

The memory capacity and transfer speed of the GDDR5X were different from those of the GDDR5. The memory was raised to 16GB, and the transfer speed has been enhanced to 80-112 GB/s. The GDDR5X was the name of this. But in the early going, it was limited to usage with certain Pascal-based GPUs from Nvidia. But as more and more people became aware of how it differed from the GDDR5, sales of it began to rise. However, it features chips with 4,6 and 8 megabytes of memory.

The features of GDDR5X

  • The maximum capacity of GDDR5X is 16 GB.
  • Bus width is 8 GB per chip.
  • I/O configuration is x16/x32.
  • Access granularity is 64B/32B(PC mode).

  • Only 1 channel Count.

WPA3 Features

Wi-Fi Protected Access 3, or WPA3, is the most recent version of widely used wireless network security. When compared to the widely used WPA2 standard, it increases security while maintaining backward compatibility. WPA3 was released by the Wi-Fi Alliance later in 2018. Companies have been using WPA2 protocols since 2004, and the new regulation expand upon them. WPA3 offers forward secrecy, with personal mode supporting 128-bit encryption and corporate mode supporting 192-bit encryption. WPA3 employs a less dangerous first key exchange technique called simultaneous authentication of equals in place of pre-shared key exchange.

The main key features of WPA3 are it is management frame protection, Transition mode, And simultaneous authentication of Equal(SAE). So let us understand the main key features of WPA3 to better understand this topic.

WPA2 uses the AES standard rather than the RC4stream cipher, in contrast to WEP and WPA. WPA's TKIP is replaced by CCMP. In contrast, WPA3 is 128-bit encryption in WPA3 personal mode(192-bit in WPA3-enterprise) and forward secrecy. WPA3 also replaces the pre-shared key exchange with simultaneous authentication of equals, a more secure way to do an initial key exchange.

What are the main key features of WPA3?

Management Frame Protection

The unicast management frames are encrypted to stop unauthorized client authorization. As a result, WIDS/WIPS systems will depend more on alerting the system administrator about rogue or honeypot APs, for example, and will have fewer options to impose customers' policies using brute force methods.

Transition mode

The enhanced open, personal, and enterprise modes can all function in transition mode. For clients that do not support WPA3, this implies returning to WPA2.

Simultaneous authentication of equal(SAE)

Even in cases where password complexity criteria are not met, SAE offers a more secure password-based authentication and key agreement process. It guards against attacks using brute force and makes it much more difficult for someone to decrypt a session either during or after it has begun just by knowing the passphrase.

What is WPA3?

What is Wi-Fi protected Access 3?

WPA3, or Wi-Fi protected access, is the most recent Wi-Fi encryption standard. Device that support the WPA3 standard will have an added layer or protection if you activate WPA3, on your eero network. This includes MEP(management frame protection), SAE(Simultaneous Authentication of equals), and a novel encryption techniques.

WPA3 was released by the Wi-Fi alliance probably in 2018. Companies have been using WPA2 protocol since 2004, and the new regulations expand upon them. In order to make Wi-Fi safer and simpler for everyone, the Wi-Fi alliance works to develop new technologies , campaigns and regulations. Manufactures need a year or two to make their goods in line with company standards, which are usually released with considerable fanfare.

The purpose of WPA3 is to increase wireless network security. Compared to WPA2, it offer significantly better data protection for data travelling over home and business Wi-Fi networks. Better protection for weak passwords, encryption for open and personals networks, and enhanced security for networks used by business are among the updates to WPA3.

What Differentiates WPA3 from WPA2?

By now, a few years after WPA3 was first announced in 2018, you have probably aware of the term. Additionally, you might have even found it in the setting menus, depending on how recent your Wi-Fi router and devices are. What exactly is the difference between WPA2 and WPA3, and why would you think about utilizing WPA3?

Why does WPA3 have any important?

WPA3 is still the industry standard for wireless security and is a requirement for Wi-Fi certified devices. WPA3 is a general advancement over WPA2, its predecessor. By permitting stronger authentication than WPA2, offering greater cryptographic strength, and increasing the resiliency of critical networks, WPA3 aims to enhance Wi-Fi security. Because Wi-Fi network are used intended and secured differently in different environment the more recent standard also offer unique benefits for personal and business use. For instance, WPA3, personal network provide better defiance against password guessing attempts, whilst WPA3 enterprise network enhanced network security procedures

What is WEP?

What is Wired Equivalent Privacy (WEP)?

An IEEE standard security technique for wireless 802.11 networks was released in 1997 and is called wired equivalent privacy (WEP). It was quickly considered to be extremely inadequate and replaced by WPA, WPA2, and 802.11i. The purpose of WEP is to guard against cyberattacks and encrypt wireless communications. It is a very weak authentication mechanism even making it easier for an attacker to find out the encryption key. As a result, the specification did away with the WEP authentication.

With WEP, data is encrypted using a hexa decimal 64 or 128-bit key. Because this is a static key, all traffic is encrypted using a single key, no matter the device. A computer connected to a network can exchange encrypted communication while keeping the content hidden from outsiders via a WEP key. To establish a connection to a network with wireless security enabled, you need this key.

Initially, WEP was able to prevent main-in-the-middle attacks, which was one of its primary objectives. Over time, however, a number of security vulnerabilities were found in the WEP standard, even with protocol modification and larger key sizes. In 2004, the Wi-Fi alliance formally deprecated WEP due to security flaws. Although it is occasionally still in use, WEP security is now regarded as outdated. This is either because devices that enable encryption are too old to support it or network managers haven't updated the default on their wireless routers.

What is x86 Architecture?

What is x86 architecture?

The term "x86 architecture" refers to an instruction set architecture (ISA) series for computer processors. The Intel Corporation developed the x86 architecture, which describes how a processor handles and executes different instructions received from software programs and operating systems (OS). Because of the complex instruction set computer (CISC) design of Intel x86 processors, there are more special purpose registers than general purpose registers. The ISA version is indicated by the x in x86. 

Microsoft Win32 takes advantage of the x86 CPU in 32-bit flat mode. In this guide, the flat mode will be the sole topic we cover.

Features of x86

  • The computing architecture is complex instruction set computing (CISC).
  • x86 has less memory but more available resistors.
  • To complete complex instructions, numerous cycles are needed.
  • Make use of data execution prevention (DEP) software.
  • designed to handle complicated addresses while utilizing fewer pipelines.
  • The hardware method optimizes system performance.

Application of x86

What is x64?

What is x64 architecture?

The x64 also referred to as the x86-64 is a family of computer processor instruction set architectures that is similar to the x86. In contrast to x86, x64 uses 64-bit CPUs rather than 32-bit ones and an operating system. Formally, it is known as AMD 64 and Intel 64, respectively, according to its manufacturers.

Under the designation x86-64, it was first conceptualized. More specifically, the instruction set extension for x86 that allows 64-bit code is called x64 architecture.

History about x64

The majority of PC CPUs in the 1980s and 1990s were 32-bit. One of the first 64-bit gadgets to hit the mainstream was the Nintendo 64 game system, which was released by Nintendo in 1996. Interestingly the console's RAM was only 4 megabytes, or 1/1000th of a 32-bit processor's maximum 4 gigabytes. However, it made room for the additional 64-bit processor. The popularity of x64 CPUs increased in 2000 and 2010. Apple and Microsoft both produced 64-bit operating system versions. Almost all desktop and mobile devices manufactured after 2010 have been equipped with x64 processors. Nowadays the majority of apps are 64-bit as well.

What is Wi-Fi Protected Access 2(WPA2)?

What is Wi-Fi Protected Access 2(WPA2)?

An improved version of WPA, known as WPA2, was released in 2004. The latest version of the Wi-Fi-protected access wireless security protocol is called WPA2(Wi-Fi-protected access 2). Similar to WPA1, WPA2 was created with Wi-Fi network security and protection in mind. Only those who possess your network password can access the encrypted data that is broadcast or received over your wireless network to WPA2. 

The advanced encryption system(AES) was introduced by the WPA2 system as a benefit, taking the place of the more susceptible TKIP system in the original WPA protocol. AES offers robust encryption which is used by the US government to safeguard confidential information. WPA2 has gained widespread acceptance and is regarded as the industry standard for protecting wireless networks. WPA2 is used by most routers and Wi-Fi networks. 

Pros of WPA2

  • Addresses many security flaws of its predecessors
  • Use the strongest encryption method -AES
  • The 256-bit key for encryption
  • Required by the Wi-Fi alliance for use on all wi-fi certified products
Cons of WPA2

What is WiFi Protected Access (WPA)?

What is WPA?

WPA stands for WiFi-protected Access,  It is wired equivalent privacy(WEP) technology that has been superseded by WPA, or WiFi-protected access, which is a network security standard that is currently required for wireless networks to safeguard them through encryption and authentication. Franklin Delano Roosevelt, the president at the time, established the Work Progress Administration (WPA) in 1935 as a way to increase employment and the purchasing power of Americans with low incomes. The WPA, which was put into place during the height of the great depression, sought to eradicate high unemployment by employing millions of skilled and unskilled people in a variety of activities ranging from manufacturing and art to the building of public buildings and infrastructure.

In order for WPA to ensure that WiFi networks are secure user must enter a password for authentication. It is compatible with dial-in remote authentication servers(RADIUS) and authentication servers. Better data encryption is an additional benefit it has over WEP. 

Features of Wired Protected Access(WPA)

  • It is an advanced Encryption standard
  • Built-in Authentication allows user access without the need for a password
  • Temporan key integrity protocol(TKIP) encryption was created via the WiFi alliance and IEEE 802.
  • A security improvement for WEP encryption, which is used on wireless networks, is the message integrity check.

Password Authentication Protocol(PAP) | Features of PAP Protocol | PAP Advantages and Disadvantages

What is a Password Authentication Protocol(PAP)?

Password authentication protocol(PAP), is an authentication technique that verifies using passwords. It is a password-based authentication protocol that conforms to the Internet standard. PAP does not encrypt data in any way. It is sent to the authentication server in plain text. PAP authenticates users based on their supplied username and password through a two-way handshake.

Features of PAP

  • It is noninteractive
  • PAP is straightforward to implement and understand
  • It uses a two-way handshake protocol
  • All network operating systems support PAP
  • The password is sent in cleartext
  • PAP is relatively easy to configure
  • PAP supports both one-way authentication and two-way authentication
  • It is widely supported in various networking and telecommunication technologies
  • PAP allows the server to verify the client's password directly
  • PAP provides a basic level of authentication
Advantages of Password Authentication Protocol

  • PAP is straightforward to implement and understand.
  • It is more advanced technology.
  • It has more additional hardware and software.
  • PAP authentication is relatively easy, and testing purposes.
  • It is relatively simple and inexpensive.
  • It is widely supported in various networking and telecommunication technologies.

  • Disadvantages of Password Authentication Protocol
    • It may become complicated when users are asked to generate complex passwords that must meet certain specifications like a minimum length, and special character numerals.
    • It only uses a static password and offers no defense against brute force attacks, in which an attacker tries a variety of passwords until they find the right one.
    • The fact that PAP does not encrypt the username and password during transmission is one of its greatest weaknesses.
    • PAP is not suggested for use over untrusted networks, like the open internet, because of its security flaws.

    CHAP Protocol | Features of CHAP | Chap Packet | Advantages and Disadvantages of CHAP

    The IETF(Internet Engineering Task Force) developed the challenge handshake authentication mechanism (CHAP), which is a point-to-point protocol (PPP) authentication mechanism. When the link first starts up, it is utilized.

    Features of CHAP

    • CHAP is achieved through a challenge-response mechanism.
    • It is more secure than static password-based authentication.
    • It periodically authenticates to see if communication is occurring with the same device or not.
    • It uses a way to hash a function called MD5.
    • CHAP offers flexibility in selecting the level of security by a variety of authentication techniques.
    • Since the password is not communicated in plaintext, CHAP is resistant to eavesdropping attempts since attackers are unable to quickly intercept and decode the password.
    • CHAP is a popular option for protecting PPP connections.
    • The CHAP challenge has a counter which helps prevent a replay attack.

    Chap Protocol Packet


    Challenge packet

    At the beginning of the CHAP3 way handshake the authenticator sends a packet to the peer known as a  challenge packet. To check if the connection has not changed, challenge packets are frequently issued as well. It includes an identifier value, a value field with a random value, and a name field with the authenticator's name. The name field is used to search for passwords. A one-way hash valye is constructed using the name field and the MD5 hash generator.

    Response packet

    The client responds to the challenge by hashing the challenge value and its secret password or key using a one-watch hash function. A response packet carrying the outcome is delivered back to the server.

    Success or failure packet

    The response packet was downloaded by the server from the client. Using its copy of the shared secret and the challenge it has been given, it determines its own expected response. Authentication is successful if the calculated answer and the one from the client agree. when the client has been successfully authenticated and access to the network or resources has been allowed, the NAS then sends a success packet. The server sends or packet and denies access if the replies do not match.

    Advantages of CHAP

    Enhance security

    CHAP doesn't send passwords in plaintext, it is safer than the outdated password authentication protocol(PAP)

    Compatibility

    CHAP is simple to install and use in a variety of network situations. 

    Protection against replay attacks

    CHAP prevents replay attacks when an attacker intercepts and reuses authentication data by using a different challenge for every authentication attempt.

    Scalability

    CHAP is capable of supporting the large number of users and devices on the network.

    Support for strong hash functions

    CHAP allows the calculation of answers using strong cryptographic hash functions like MD5 or SHA1.

    Widespread support

    CHAP is a possible option for many network authentication scenarios since it is widely supported by a variety of networking technologies including PPP and VPNs.

    Prevent replay attacks

    CHAP is able to prevent replay attacks by making sure that the same challenge can never be used twice.

    Disadvantages of CHAP

    Requires a pre-shared key

    CHAP needs a pre-shared key, which can be challenging to handle in large-scale network systems.

    No initial encryption

    CHAP's main function is authentication, it does not however encrypt the data being sent.

    Shared secret management

    CHAP relies on shared secret passwords between the client and the server, just like many password-based authentication techniques.

    Lack of mutual authentication

    Because CHAP does not support mutual authentication, the user cannot be authenticated by the network in the same way that the network is authenticated by the user.

    What is DIMM

    What is DIMM?

    DIMM acronym for Dual In-line Memory Module. It is a type of computer memory that install in the motherboard's memory slots. DIMM is used to provide additional random access memory(RAM)  to computer systems, allowing for increased performance and multitasking capabilities. Since personal computer processors have a 64-bit data width, DIMM employs a 64-bit data route.  Desktop PCs, laptops, printers, and other devices frequently employ DIMMs. DIMMs feature multiple electrical contacts on both of their rectangular sides.

    DIMM circuit boards changed as faster dynamic random access memory(DRAM) was created. In order to boost data throughput, modern DIMMs based on double data rate fourth generation(DDR4) SDRAM chips connect to the computer motherboard using 288-pin connectors. The 64-bit route was able to accommodate growing volumes of data as the RAM chips' clock speeds grew.\

    What is CHAP in networking

    Definition of CHAP

    The IETF developed the challenge handshake authentication protocol(CHAP), It is a PPP authentication protocol. It is used when the link first starts up. Additionally, it runs routine checks to see if the router is still in contact with the same host. CHAP is a three-step process of exchange of shared a secret. where the password authentication protocol(PAP) uses a two-way handshake for authentication between the remote user and the PPP server. It offers more security than PAP due to the variable nature of the value to determine the hash value.
