Analise as seguintes afirmações relacionadas a conceitos básicos de Internet, protocolos TCP/IP e Segurança da Informação.
I. A assinatura digital é o processo de manter mensagens e dados em segurança, permitindo e assegurando a confidencialidade. Quando utilizam apenas chaves privadas, as assinaturas digitais são usadas para fornecer serviços de integridade de dados, autenticação e não repúdio.
II. Um algoritmo de criptografia simétrica requer que uma chave secreta seja usada na criptografia e uma chave pública diferente e complementar da secreta, utilizada no processo anterior, seja utilizada na decriptografia. Devido à sua baixa velocidade, a criptografia simétrica é usada quando o emissor de uma mensagem precisa criptografar pequenas quantidades de dados. A criptografia simétrica também é chamada criptografia de chave pública.
III. Na Internet, O UDP (User Datagram Protocol) é um protocolo de transporte que presta um serviço de comunicação não orientado a conexão e sem garantia de entrega. Portanto, as aplicações que utilizam este tipo de protocolo devem ser as responsáveis pela recuperação dos dados perdidos.
IV. Os servidores de diretório responsáveis por prover informações como nomes e endereços das máquinas são normalmente chamados servidores de nomes. Na Internet, os serviços de nomes usado é o Domain Name System (DNS). O DNS apresenta uma arquitetura cliente/servidor, podendo envolver vários servidores DNS na resposta a uma consulta.

Analise as seguintes afirmações relacionadas a conceitos básicos sobre Sistema Operacional Windows 2000 e Segurança da Informação.
I. No sistema operacional Windows, versão que permite configurações de cotas de disco, ao se selecionar a opção " Negar espaço em disco para usuários excedendo o limite de cota", os usuários que excederem seus limites de cota receberão uma mensagem informando que o limite do espaço em disco será excedido mas poderão gravar dados adicionais no volume. O espaço será negado somente quando o usuário efetuar novo logon. Neste caso, o servidor enviará uma mensagem solicitando ao usuário que exclua ou remova alguns arquivos existentes no mesmo.
II. É possível definir permissões de arquivo e pasta apenas nas unidades formatadas para usar o NTFS.
III. O tamanho padrão do arquivo de paginação da memória virtual pagefile.sys criado durante a instalação do Sistema Operacional tem 1,5 vezes a quantidade de RAM instalada no computador. É possível otimizar o uso da memória virtual dividindo o espaço entre várias unidades e especialmente removendo-a de unidades mais lentas ou muito acessadas.
IV. Um backup diário é aquele que copia somente os arquivos alterados desde o último backup incremental e marca os arquivos como tendo sofrido backup.

II. Um Driver de Dispositivo é um programa que permite que um dispositivo, como uma placa de rede, se comunique com o Sistema Operacional. Para os dispositivos ativados no Sistema Operacional, os drivers de dispositivo são carregados automaticamente quando o computador é inicializado.
III. A memória em um computador é organizada em uma hierarquia que, considerando-se o tempo de acesso da mais rápida para a mais lenta, é ordenada como: Memória principal; Registradores; Cache; Armazenamento secundário em discos rígidos(HD); Armazenamento secundário em unidades de rede compartilhadas; Armazenamento secundário que utilizam acesso USB; Armazenamento secundário em CD-ROM e Armazenamento off-line(fitas).
IV. Com relação à memória de acesso aleatório (Random Access Memory - RAM), o termo "aleatório" significa que o processador, ao buscar um dado, deve varrer aleatoriamente todas as células de memória existentes no computador, até encontrar o dado desejado.

The perils of prosperity
Source: The Economist
April 27th 2006 (Adapted)
Midway through the first decade of the 21st century,
economic growth is pulling millions out of poverty. Growth,
so devoutly desired yet often so elusive for developing
countries, is occurring in China and India on a heroic scale.
Yet once affluence is achieved, its value is often questioned.
In the 1960s and 1970s, economists started worrying about
environmental and social limits to growth. Now Avner Offer,
professor of economic history at Oxford University, has
added a weighty new critique to this tradition.
“The Challenge of Affluence” accepts that the
populations of poor countries gain from growth, but says
that the main benefits of prosperity are achieved at quite
modest levels. Its central thesis is that rising living standards
in Britain and America have engendered impatience, which
undermines well-being. The fruits of affluence are bitter
ones, and include addiction, obesity, family breakdown and
mental disorders.

The global union
Source: Newsweek Special Edition
Dec 2005 – Feb 2006 (Adapted)
What would a global union look like? Think more
corporate partnership than class struggle. Today, capital is
global and employers are global. Companies, not countries,
make the rules. To survive, unions need to find their niche.
Global companies are going to need an organization that,
in a sense, will manage their labor and protect workers’
rights. A global union would set standard practices and
codes of conduct – perhaps even minimum wages and
work hours.
My critics in the labor movement cringe when I use
words like “partnership” and “value added”. The reality is
that unions need to add value or corporations will ignore
us. If we want an equitable stake in the company, we need
to define what our goals are. We can’t just demand a raise
in pay without offering an incentive to the company. We’re
already far behind multinational corporations in the global
game. We made the mistake of transferring the industrial
model of unionism of the last country to the 21st. We lost
market share: in 1960, one in four workers was in a union;
now it’s one in 12.

The future of work
Source: Newsweek
Jan 30th, 2006 (Adapted)
Many of the rich world’s notions about old age are dying.
While the streamlining effects of international competition
are focusing attention on the need to create and keep good
jobs, those fears will eventually give way to worries about
the growing shortage of young workers. One unavoidable
solution: putting older people back to work, whether they
like it or not. Indeed, cutting-edge European economies
like those of Finland and Denmark have already raised
their retirement ages, reversing the postwar trend toward
ever-earlier retirement. Others are under severe pressure
to follow suit, as both the European Commission and the
Organization for Economic Cooperation and Development
(OECD) have recently warned their members that their
future prosperity depends on a growing contribution from
the elderly.
This erosion of one of the cornerstones of the good
life – relaxed golden years – has not gone unremarked. In
the last year, Belgium, Italy and France have all been hit
with massive protests against pension reforms that would,
among other things, have raised the retirement age.

Assinale a opção que apresenta justificativa correta para o emprego da vírgula correspondente.
O setor de petróleo brasileiro merece legitimamente a comemoração pelo sucesso presente, (1) e as perspectivas do futuro contemplam êxito no trabalho de todas as empresas que atuam nessa área no Brasil, em especial, a Petrobras. Este futuro terá, com certeza, a marca do realismo e da humildade, (2) que são duas virtudes que, invariavelmente, andam juntas. Realismo no reconhecimento das possibilidades e limitações de todas as coisas. Humildade na renúncia a qualquer espécie de soberba, (3) de cega arrogância, (4) entendendo que a construção de uma nação e a consolidação de empresas fortes não são façanhas apenas de um punhado de homens, mas, sim, do esforço de uma sociedade inteira, (5) unida pelos laços multiplicadores da solidariedade nacional.
