Types of operating systems
Real-time
A real-time operating system is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main objective of real-time operating systems is their quick and predictable response to events. They have an event-driven or time-sharing design and often aspects of both. An event-driven system switches between tasks based on their priorities or external events while time-sharing operating systems switch tasks based on clock interrupts.
Multi-user
A multi-user operating system allows multiple users to access a computer system at the same time. Time-sharing systems and Internet servers can be classified as multi-user systems as they enable multiple-user access to a computer through the sharing of time. Single-user operating systems have only one user but may allow multiple programs to run at the same time.
Multi-tasking vs. single-tasking
A multi-tasking operating system allows more than one program to be running at the same time, from the point of view of human time scales. A single-tasking system has only one running program. Multi-tasking can be of two types: pre-emptive and co-operative. In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking, as does AmigaOS. Cooperative multitasking is achieved by relying on each process to give time to the other processes in a defined manner. 16-bit versions of Microsoft Windows used cooperative multi-tasking. 32-bit versions of both Windows NT and Win9x, used pre-emptive multi-tasking. Mac OS prior to OS X used to support cooperative multitasking.
Distributed
A distributed operating system manages a group of independent computers and makes them appear to be a single computer. The development of networked computers that could be linked and communicate with each other gave rise to distributed computing. Distributed computations are carried out on more than one machine. When computers in a group work in cooperation, they make a distributed system.
Embedded
Embedded operating systems are designed to be used in embedded computer systems. They are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources. They are very compact and extremely efficient by design. Windows CE and Minix 3 are some examples of embedded operating systems.
Based on the text above, judge the following item.
Systems that use time-sharing are not considered to be multiuser systems, since they do not allow the simultaneous access of several users to a computer.

Com relação a prisões processuais, julgue o item subseqüente, considerando a legislação e a jurisprudência do STF relativas a esse tema
Configura reformatio in pejus, que invalida a ordem de prisão, a decisão de tribunal de justiça que, ao negar provimento à apelação da defesa, determina a expedição de mandado de prisão contra recorrente que adquiriu, na sentença condenatória, o direito de recorrer em liberdade até o trânsito em julgado da decisão.

Em relação aos conceitos de programação orientada a objetos e lógica de programação, julgue o item subsequente.
Em programação orientada a objetos, polimorfismo é o princípio pelo qual duas ou mais classes derivadas da mesma superclasse podem invocar métodos que têm a mesma assinatura, mas comportamentos distintos.

A respeito de competência em direito processual civil, julgue o item a seguir.
Reconhecida a conexão entre os processos, o juiz poderá determinar a remessa dos autos ao juízo prevento, mesmo após a prolação da sentença, a fim de evitar decisões contraditórias.
