How will arrange physical resources of computer center?
Answer:
Popular classroom seating arrangements for computer labs each have their benefits and drawbacks depending on class management and teaching needs.
Computer labs in schools are becoming a more popular way for schools to provide technology access to all classes. These labs tend to be designed around space constraints instead of instructional needs, which can make teaching and monitoring difficult depending on the needs of the teacher and how the lab is intended to be used.
There are three common arrangements for labs, each providing different uses of space and addressing different instructional needs. Though not one of them is ideal for every situation, each one provides both benefits and drawbacks to educational needs.
Computers in Clusters of Four
Clusters of four is a computer desk arrangement where there are four stations facing each other in a square, and several of these clusters spaced around the room. It is similar to a cubicle setup that might be experienced in a business setting. Computers may be on tables, or in cubicles to minimize distractions between student.
Clusters of computer stations is ideal for individual work and can be difficult for groups to collaborate. The teacher spends much time either sitting at a desk using software to monitor students to make sure they stay on task. When walking around the room it is impossible to view all stations at once, which can make it difficult to interact with students while maintaining a watchful eye on other students'behavior.
Rows of Desks Facing a Board
This arrangement is similar to a lecture hall setup, and the teacher's computer might be in the front or back of the room. Sometimes rows are long with one aisle on the outer edge or down the middle of the room. To get to a student the teacher needs to have enough space between the chair and the next row to comfortably walk.
Rows of desks works well if there is a frequent need for students to watch a projection of the teacher's computer and duplicate steps at their own computer. However, this limits the teacher to teaching from the back of the room to monitor usage and watch for students who need help or from a desk at the front of the room, facing the students, and running software to help monitor each students' machine.
horseshoe Facing the Walls
This modification to the standard horseshoe desk arrangement typically with an inner horseshoe or block of tables behind the students. It allows the teacher to teach from almost anywhere in the room, walk behind students and help when needed, and reduces classroom management issues found in the first two. When tables are placed in the center of the room it also gives a place away from the computers when students need to write or do other activities that do not require a computer.
The drawbacks to the horseshoe arrangement is that students need to turn when instruction is in the front of the class or if they need to follow a demonstration. Students will have difficulties following teacher led steps because of the frequent need to turn.
Clusters of four, rows, and a modified horseshoe arrangement are common arrangements found in school computer labs. Each has its educational benefits and drawbacks, though some of these can be overcome by purchasing specialized software.
What is the role of CPU in the computer's functioning?
The CPU is the 'brain' of the computer. It is where all the searching, sorting, calculating and decision making takes place. The CPU contains a tiny quartz clock. Each time this clock 'ticks', one instruction can be dealt with by the CPU. So the more times this clock ticks per second, the more instructions the CPU can carry out and the faster things get done.
The speed of the CPU is measured in either Megaherts (MHz) or more commonly now in Gigahertz (GHz). A 1 MHz CPU can carry out one million instructions per second. A 1 GHz CPU can carry out 1 billion instructions per second!
A typical CPU installed in a computer today would run at around 3 GHz.
What is the importance of secondary storage?
Secondary storage can be used to restore a backup of your files if you have to format. You can use it if you run out of room on your main hard drive. If it is external secondary storage you can also bring it with you if you need to access files at work or somewhere else.
Commonly used types of secondary storage are the USB drive and Floppy Disk, as referred to in the joke 'Can you turn my floppy disk into a hard drive?' which is impossible!

A harddrive is a device that stores data which can be retrieved later by an operating system. A harddrive is commonly made with stacks of platters on which data is stored maganetically and is read by the read head (little devices that move around the platters connected by an armiture)
What are Branded company in Computer?
Branded computers are manufactured by big companies like Packard Bell, Acer, Dell, Compaq, IBM, Gateway and others. These big names have built their reputation over the years. Therefore they do take quality seriously, since their reputation is at stake. Branded computers save time to the user, instead of having to assemble his own personal computer, which can be a difficult task to a non technical person.
When you buy a branded computer you are covered with a guarantee and there are less chance that something will go wrong, than if you had to assemble the computers yourself. The difference between branded and assembled computers is that while branded computers are built in mass productions plants, assembled computers are built by a technical person or by the computer owner.
When one buys a branded computer, he has a quality assurance that the computer components have been tested thoroughly. A branded company is expected to make use of quality parts and not cheap ones. This means that the computer owner gets good quality for a reasonable price. Branded computers are expected to give stable performance since all parts are manufactured by the same company, while in assembled computers one can experience hardware conflicts and other technical problems.
The buyer also enjoys experienced technical support from the mother company, while if you buy an assembled computer you are at the mercy of the after sales service of the shop keeper. Another advantage of a branded computer is that it looks unique in design and professional. Branded computers contain original software such as operating system and common applications. Even extended warranties are available. Branded computers come with PC restore CD.

Is there a HDMI port on a computer?
The HDMI (High Definition Media Interface) slot is normally found along with the other video output slots either on the back of a desktop casing or on the sides of a laptop. It looks like a USB port, with two small notches missing from the corners of one side.
It is normally standard with modern PC's (within the last 3 years), but would have been an expansion card with older PC's
Where does the most calculations done in a computer take place in?
The Arithmetic Logic Unit (ALU) inside the Central Processing Unit (CPU) of the computer.
Most modern computers however do not have a single general purpose ALU that handles everything, but instead have several independently functioning special purpose ALUs optimized for specific data types (e.g. integer numbers: I-ALU, floating point numbers: FP-ALU, boolean logical values: LU).
Differences between windows platform computers and Macintosh platform computers?
It is the difference between a specific proper pronoun and a generic pronoun. Mac is the nickname for the Macintosh computer made by Apple. PC is an acronym that comes from the terms personal computer. Only the Macintosh is a Mac. The Macintosh is also a PC.
Both the PC and the Mac are very good for their own reasons. Here is a list of the main advantages of each:
Advantages of a PC
- Much more popular, over 80% of all desktop computers use Windows
- Uses a Start Menu and taskbar at the bottom (by default)
- Easier for an inexperienced user
- Considerably cheaper
- Compatibility/Availability (most applications are developed for Windows only)
- Plays commercial games
- More customizable, hardware can be upgraded very easily.
Advantages of a Mac
- Looks much better
- Uses a Dock and a bar at the top (by default)
- Safer (almost zero viruses)
- Simpler, more reliable (less configuration, less processes)
- Macs are made by Apple themselves (not many are custom-made)
- Much more productive (Audio, Video and Image editing software is much better)
- You can install Windows easily, alongside OS X (dual-booting).

Trace the history of computer?
By the early nineteenth century, the capitalist culture's appetite for mathematics had outgrown its tools. A pair of British visionaries, Charles Babbage and Augusta Ada King, imagined the construction of an Analytical Engine-a mechanical computer that would automatically and reliably form these tasks. In 1939 a German engineer named Konrad Zuse completed the Z1, the first programmable, general-purpose digital computer.
How computer CPU casing is made?
