Distributed Operating System (DOS)
DoS attacks can be carried out in 2 different ways: by flooding devices or crashing them. Flood assaults happen when a system receives too much traffic for the server to buffer. It may slow down and eventually shut down the server. The following are some of the most common floods: Buffer overflow attacks – A buffer overrun is the most common DoS tactic. The goal is to send more data to a network interface than the engineers expected. ICMP flood – exploits vulnerable network devices by sending bogus packets that ping every machine on the targeted network instead of just one. SYN flood – sends a server a connection request but does not complete the handshake. Other DoS attacks exploit weaknesses in the target system or service to bring it down. These attacks involve receiving input that exploits the target’s vulnerabilities, leading the system to crash or become considerably destabilised, making it hard to access or use.

There are multiple versions of DOS that have been available. * MS-DOS was manufactured by Microsoft. * PC-DOS was manufactured by IBM. * DR-DOS was manufactured by Digital Research Inc. There are other versions of DOS available, but the three listed were the most widely distributed.
Distributed Denial of Service (DDoS) attack is another type of DoS attack. These attacks involve numerous systems coordinating a synchronised DoS attack on a single target. The key difference is that the target is attacked from numerous directions simultaneously rather than from a single entity. DDoS attackers frequently employ a , a collection of hijacked devices connected online, to launch large-scale attacks. Attackers use command and control software to exploit security flaws or hardware weaknesses to control many devices.
A denial of service attack. (DoS) This type of attack includes a variety of methods for denying legitimate users access to a network. A Distributed Denial of Service attack (DDos) is more specific type of DoS attack which includes many, mostly infected, devices sending traffic towards a single source to overload the target and prevent normal access.
A DoS attack can mimic non-malicious availability concerns like network congestion or a system administrator performing maintenance. The following signs may suggest a DoS or DDoS attack: Irregular network performance with reduced speed Inability to access any website Certain websites turn out to be unavailable Monitoring and analysing network traffic is the most prominent way to identify and evaluate a DoS attack.
PC-DOS is the original operating system for the IBM PC. It is basically the same operating system as MS-DOS, but was distributed by IBM instead of being licensed directly from Microsoft.

Network Operating system, NOS, is software allows the system to connect to a network. Disk Operating System, DOS, is software that uses the information that is stored on a disk.

Intruders ,attacker,or some time user who want to destroy server and its application. After DoS attack server and their application are not able to respond.
