Basic Information

Assuming you haven't been living in a cave or under a rock for the last few decades, you are probably aware that an amazing computer revolution has rapidly changed the way much of the world works. Developments in radio, television, radar, transistors, computers, and robotics have fundamentally altered human life. The field of Computer Engineering is at the epicenter of this development. It encompasses a wide range of topics including operating systems, computer architecture, computer networks, robotics, artificial intelligence, and computer-aided design.

If you major in Computer Engineering, you'll learn all about the hardware and software aspects of computer science. You'll gain a solid understanding of circuit theory and electronic circuits, too. Also, because Computer Engineering is closely linked with Electrical Engineering, the fields are found in the same department at many universities. Consequently, many undergraduate programs incorporate most of the core curricula in both electrical engineering and computer science so graduates will be prepared to work in either field.

Computer Engineering is a difficult major but it's a major that's in demand. Software engineering companies, telecommunications firms, designers of digital hardware, and many other business enterprises hire Computer Engineering majors right out of college and pay them well. Computer Engineering also makes great preparation for medical school, business school, and law school (particularly if you want to specialize in patent

Computer science

From Wikipedia, the free encyclopedia

Computer science or computing science (abbreviated CS) is the study of the theoretical foundations of information and computation and of practical techniques for their implementation and application in computer systems.^[1][2] Computer scientists invent algorithmic processes that create, describe, and transform information and formulate suitable abstractions to model complex systems.

Computer science has many sub-fields; some, such as computational complexity theory, study the properties of computational problems, while others, such as computer graphics, emphasize the computation of specific results. Still others focus on the challenges in implementing computations. For example, programming language theory studies approaches to describe computations, whilecomputer programming applies specific programming languages to solve specific computational problems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans.

The general public sometimes confuses computer science with careers that deal with computers (such as information technology), or think that it relates to their own experience of computers, which typically involves activities such as gaming, web-browsing, and word-processing. However, the focus of computer science is more on understanding the properties of the programs used to implement software such as games and web-browsers, and using that understanding to create new programs or improve existing ones.^[3]

Computer science deals with the theoretical foundations of information, computation, and with practical techniques for their implementation and application.

Computer Virus

What is a computer virus?

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.

A virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk.

Computer viruses are often spread by attachments in email messages or instant messaging messages. That is why it is essential that you never open email attachments unless you know who it's from and you are expecting it.

Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.

Computer viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.

To help avoid computer viruses, it's essential that you keep your computer current with the latest updates and antivirus tools, stay informed about recent threats, run your computer as a standard user (not as administrator), and that you follow a few basic rules when you surf the Internet, download files, and open attachments.

Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection.

Static Random Access Memory (SRAM) is a type of RAM used in various electronic applications including toys, automobiles, digital devices and computers. Static RAM or SRAM only holds its contents while power is applied. It differs from dynamic RAM (DRAM) in that DRAM must use refresh cycles to keep its contents alive. SRAM holds data as a static ‘image’ as indicated by the name, until written over or lost from powering down.

SRAM is more expensive, faster and more power-efficient than DRAM for most uses. However, its internal structure also makes it less dense, and therefore a less ideal candidate for the main memory inside personal computers. Instead, SRAM is utilized for critical, secondary uses such as fast cache memory for central processing units (CPUs). CPU cache can significantly boost a computer’s overall performance with a rather small footprint of dedicated memory.

Compared to DRAM, SRAM is more power-efficient when idle. However, overclocking the CPU can negate this power-saving advantage. Overclocking causes the CPU to work faster than its marketed specifications. In such a case the SRAM cache spends less time in the power-saving idle mode.

SRAM is also present in many modern hard drives as disk cache. The disk cache is used to temporarily store data that is accessed frequently. Retrieving data from the SRAM cache is many times faster than retrieving it from a standard, platter-designed hard drive. You might also find SRAM in modem routers, printers, digital cameras, and compact disk (CD) or digital versatile disc (DVD) decks. Toys with electronic interfaces also commonly use SRAM.

SRAM can be synchronous, or asynchronous. Asynchronous SRAM is not dependent on the clock frequency of the CPU, while synchronous SRAM synchronizes with the CPU clock speed.

SRAM can be incorporated into one of two types of transistor chips: The bipolar junction transistor, or the metal-oxide-semiconductor field-effect transistor (MOFSET). The former makes SRAM extremely fast but also consumes a lot of power. This type of transistor is used in specialty applications. MOFSET is the more common type of SRAM used in the various applications discussed here.

SRAM should not be confused with SDRAM (Synchronous Dynamic Random Access Memory). SDRAM is a flavor of DRAM, and functions differently than SRAM.
