30 points!!! Due Tomorrow. ICT test on memory, CPU, motherboard and dedicated/embedded systems and general purpose systems. Any tips?

Just get it right and don't get stressed

Explanation:

An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.[1][2] It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today.[3] In 2009 it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems.[4]

just remember their functions and what they are.

CPU: Central Processing Unit. Also known as a microprocessor, a CPU is the brains of a computer. To be more specific, a CPU fetches program instructions from RAM (input), interprets and processes it (execution) and then sends back the computed results so that the relevant components can carry out the instructions.

Motherboard: Motherboard keeps various parts of the computer together, which allows for the proper functioning of the computer system.

Embedded system: An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations.

Dedicated system: Dedicated means reserved for a specific use.In communications, a dedicated channel is a line reserved exclusively for one type of communication. This is the same as a leased line or private line.. A dedicated server is a single computer in a network reserved for serving the needs of the network.

General purpose system: This ability makes general-purpose computer systems very flexible. Major Functions of Computer Systems. The major functions of a computer system are input, process, output and storage. Let's take a closer look at each of these major functions. Input. Any information that is put into the computer to be processed is referred to as input.

Explanation: well there you have it, good luck and u better study

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
