Difference between ARP and RARP

Both ARP and RARP are network-layer protocols. When a host needs to send an IP datagram to another host the sender needs both the receiver's logical and physical addresses. The dynamic mapping protocol supports two protocols called ARP and RARP.  So here this article gives the difference between ARP and RARP to better understand this topic.

What is ARP?

ARP stands for address resolution protocol, it is a protocol used at the network layer. Because ARP is a dynamic mapping protocol, Each host in the network is aware of another host's logical address. The host needs to send an IP datagram to another host. However, the IP datagram must be encapsulated in a frame in order to traverse the physical network between sender and receiver.

What is RARP?

A  network layer protocol is also known as RARP called reverse address resolution protocol. The RARP protocol is a  TCP/IP protocol that allows any host to obtain its IP address from the server. RARP is an adaptation of the ARP protocol that is simply the opposite of ARP.

Difference between ARP and RARP:

  • The full form of ARP is addressed resolution protocol whereas, while the RARP is reverse address resolution protocol.
  • ARP protocol retrieves the physical address of the receiver while the RARP protocol retrieves the logical address of the protocol.
  • ARP maps the 32-bit logical address to a 48 bit physical of the receiver, RARP maps the 48-bit physical address to the 32-bit logical address of the receiver.

Cable vs DSL | Difference between Cable and DSL

Cable internet is a broadband internet connection that uses your TV's local cable to connect to a modem. DSL is a modulation scheme that uses an existing two-wire copper telephone line to provide high-speed internet without clogging the line. So here this article gives the difference between cable vs DSL to better understand this topic.

What is DSL?

DSL is an abbreviation for digital subscriber line. DSL uses a sophisticated modulation scheme to pack internet data into the same pair of copper wires that carry your phone service. DSL is sometimes referred to as a last-mile technology because it is used to connect a telephone switching station to a home or office rather than between switching stations.

What is Cable?

A cable internet is a broadband internet connection that uses a modem to connect to the internet via your TV local cable. Cable internet works by transmitting data over TV channel space, with certain channels used for downstream transmission and others for upstream transmission. A cable modem can be used to achieve extremely fast web access because the coaxial cable used by cable TV provides significantly more bandwidth than telephone lines.

Cable vs DSL | Difference between Cable and DSL:

  • Cable speed is 30 Mbps but is reduced to 20-25 Mbps when sharing bandwidth, while the DSL is from 128kbps to over 100Mbps.
  • The bandwidth of cable shared speed varies depending on the number of subscribers on the network, while the DSL does not share constant speed.
  • Both have home networking possible.
  • Monthly fees of cable in average $40 to $50, while the DSL average $20 to $35.
  • A one-time set-up fee for cable is average $50 to $100, while the DSL is approximately $150.
  • Equipment required for cable is cable box and remote, while the DSL required phone jack.
  • In cable Installation visit from a technician, while the DSL can be done by yourself, but a technician is always available in case you need help with installation.
  • Cable has need security software, while the DSL needs security software from ISP.
  • Cable costs around the same as DSL, but gives a better speed to cost ratio making it efficacity cheaper than DSL, While the DSL costs the same as cable, but is significantly slower compared to cable, making it more expensive in effect.
  • Both have contracts month to month.

NAT vs PAT | Difference between NAT and PAT

Before transferring a packet, Network address translation and port address translation protocols are used to map an unregistered private address of an internal network to a registered public address of an external network. The main difference is that NAT is used to map public IP addresses to private IP addresses in a one-to-one or many-to-one relationship. PAT is the type of NAT in which multiple private IP addresses are mapped into a single public IP address via ports.

What is NAT?

NAT stands for network address translation. It is a device to improve security by preventing an outside attacker from even discovering the local network. This is due to the fact that the local addressing scheme is not contiguous with the standard IP address space used globally.

What is PAT?

PAT stands for port address translation. PAT optimizes the use of IP address space by allocating one dedicated IP address to the organization and using IP address internally as needed. PAT is the NAT extension.

NAT vs PAT| Difference between NAT and PAT:

  • NAT stands for network address translation, while PAT stands for port address translation. 
  • NAT can be considred PATs superset. PAT is a form of dynamic NAT.
  • NAT uses an IP address in the process of translation whereases  PAT uses an IP address along with port numbers.
  • NAT translates the inside local addresses into inside global addresses similarity PAT translates the private unregistered IP addresses into public registered IP addresses but unlike NAT it uses a source of port numbers also, and multiple hosts can be assigned with the same IP having different port numbers.
  • NET uses an IPV4 address. PAT also uses an IPV4 address but with port numbers. 
  • NAT has 3 types: Static, dynamic NAT, and PAT/NAT overloading/IP masquerading. While PAT also has two types: static and overload PAT. 
The key difference between NAT and PAT:
  • PAT uses IP addresses along with port numbers,, while NAT uses IP addresses along with port numbers.
  • PAT is a form of dynamic NAT.
  • NAT translates the inside local addresses into inside global addresses similarly PAT translates the private unregistered IP addresses into public registered IP addresses. However unlike NAt, PAT also uses source port numbers, allowing multiple hosts to share a single IP address while using different port numbers.

Difference Between Server and Workstation

A server is a computer that provides services to clients while the workstations are moderately powerful computers that are popular in business, scientific, and engineering applications. So here this article gives the difference between servers and workstations to better understand this topic.

What is the server?

A server is either hardware or software that responds to client requests for services. It is an internet-based business. Because it is optional to the server, this graphical user interface can be pre-installed or not.

What is a workstation?

A workstation is a computer that requests the LAN and switch services in order to perform dedicated tasks with enhanced features. In a workstation, operations take the form of business, engineering, and so on. Additionally, the graphical user interface is pre-installed because it is not an optional component of the workstation.

Difference between server and workstation:

  • A workstation is a computer to perform required tasks and accesses the internet or LAN, while the server is software that provides services when requested by workstations.
  • Workstations are like business processes, engineering, etc, while the server operation is costly network or internet-based.
  • Workstations are examples of FTP servers, and web servers, while an example of servers like kiosks, video workstations, and audio workstations.
  • Workstations are mostly Linux, Unix, or Windows NT-based, While the servers are normally installed on Linux, Solaris, Unix or windows.
  • For workstations, GUI is generally present, while the server GUI is optional.

Answer:

  • Challenge Handshake Authentication Protocol

What does CHAP mean?


CHAP is an identity checking protocol that reauthenticates the user during an online session at regular intervals. CHAP when properly implemented is far more secure than the password authentication protocol.

HDLC vs PPP | Difference between HDLC and PPP

High-level data link control (HDLC) and Point-to-Point(PPP) are two different data link layer protocols used in computer networks. the primary difference between HDLC and PPP is that HDLC is a bit-oriented protocol whereas PPP is a byte-oriented protocol.

What is HDLC?


HDLC stands for high-level data link protocol, It is an asynchronous data link layer protocol with bit-oriented code transparency. The International Organization for Standardization created it. Furthermore, it accommodates both connection-oriented and connectionless services.

What is PPP?

 
PPP stands for point-to-point protocol, it is another WAN encapsulation protocol that is based on HDLC, but it is an improved version of HDLC. When compared to HDLC, PPP has a plethora of additional features.

Difference between HDLC and PPP | HDLC vs PPP:

  • HDLC is a bit-oriented protocol, whereas PPP is both byte-oriented and bit-oriented due to its ability to be transmitted over dial-up modem lines as well as true bit-oriented HDLC.
  • HDLC does not support link authentication, whereas PPP does.
  • HDLC operates at layer 2 called as data link layer, while the PPP is operating at layer 2, and layer three is called the network layer.
  • PPP can dynamically assign and free up IP addresses based on their use. In HDLC however, this is not the case.
  • In HDLC only synchronous media can be used, PPP can work with both synchronous and asynchronous media.
  • HDLC interoperability between non-cisco devices is not possible. This limitation of HDLC, however, is removed from the PPP protocol.
  • HDLC lacks an error detection method, whereas PPP employs FCS to detect errors while transmitting data.
  • HDLC protocols have two types via ISO, HDLC, and CISCO HDLC, while the PPP uses HDLC a format as defined by ISO.
  • HDLC is used to encapsulate data without the assistance of other encapsulation protocols, whereas PPP can encapsulate data without the assistance of other encapsulation protocols such as HDLC and SDLC.
  • HDLC fails to check for the quality of the link established, while the PPP uses link control protocol to check for the quality of the established link.
  • HDLC does not support authentication. It fails to provide authentication between two nodes. While the PPP supports authentication using a protocol such as PAP and CHAP.

USB A vs USB C

The two most common categories in which USB cables are classified are USB A and USB C. The primary distinction between USB A and USB C is based on the nature of the two cables in relation to their plug-in orientation. In general USB A does not support reversibility in terms of plug-in orientation within the port, whereas USB C supports reversibility and can be plugged in either way regardless of port orientation.

What is USB A?

USB A is the most commonly used type of connector in general, and it has a rectangular shape. It is also known as the most traditional type of USB. It is also known as standard A. This cabling port is commonly found in computer-like devices such as smart televisions, gaming consoles, DVD players, and so on.

What is USB C?

USB C is the most recent type of USB cable in use. It has a square shape. The plug-in reversibility that it provides is the reason for enormous popularity. It is a high-power cable that can handle high-speed data transfer.

Difference between USB A and USB C  | USB A vs USB C:

  • The physical appearance of USB  A is different from USB  C. According to the size of the two cables, it is said that USB- A is large size-wise whereas USB-C appears small.
  • The USB-A cable appears to be wider than the USB-C cable because type C has a smaller shape and is thinner.
  • The output power of the USB-C cable is nearly 100 watts, which is significantly higher than the output power of the USB-A cable.
  • The rate of data transfer is much faster with a USB type C cable than with a USB type A cable. The USB C cable transfers data at a rate of approximately 10 gigabytes per second.
