Computer Networking

Yes you can mix the ram, but the ram will default to the slowest of the set and only run at the slower speed.

1. Testability/Increased Quality (automated testing can increase speed of testing and increase quality) 2. Code re-use (Polymorphism, Generics, Interfaces) 3. Code extensibility 4. Catch errors at compile time rather than at runtime. 5. Maintainability: If designed correctly, any tier of the application can be replaced by another that implements the correct interface(s), and the application will still work (can use multiple user interfaces, can swap out data providers, etc.). 6. Reduces large problems to smaller, more manageable ones. 7. Fits the way the real world works. It is easy to map a real world problem to a solution in OO code.

For mailing address: in some computer languages, strings or text will be the answers. For OO language, a class Address should be designed to be the template to hold onto any address information. (an address is a class with a lot of string fields for address lines, city, zip, state, county, country, province, zone, district, etc)

For internet address: some languages such as C# already provides you with Url class

Iam pretty sure that baseband coax was 50 ohm and was used for networking computer, were broadband coax is 75 ohm and used in the cable tv industry.

A baseband signal is the original signal before it is modulated onto a carrier, mulitplexed or mixed.

A broadband signal contains many channels which have been modulated or multiplexed onto a common carrier.

The significant difference is the bandwidth of each.

The impedance of the cable which carries either of them is totally irrelevant to the definition.

Splicing of optical fiber cable is done to extend a cable, making it longer, or to repair a break in it. Splicing is preferred over installation of connectors, because the connectors introduce losses and degrade reliability. Some connectors are necessary, but those are placed in a protected environment, and their use is minimized. Besides, a typical cable, with 56 or more strands, would require 56 or more connectors, and that would create a large lump in the cable.

It is both. Firstly it is a science. Computing is a science and programming is a science. However, there is an artistic element to it too. Scientifically there are a set amount of commands in any programming language with a strict syntax and rules as to how they can be used. It is up to programmers how they use them to solve a particular problem. Some of them are more creative in how they use them to solve a problem. The different programmers are using the same language and commands and have a full knowledge of the language, but they use them in different ways. Some are better at doing it than others. That is where the art and creativity comes in.

Looking at it another way, you can read a book written by a great author, because you know all of the words used in it. However, you would not have been able to create that story yourself. So although you know the same words in your language that the author does, the author is able to think of clever ideas and use the words more creatively than you can. In some ways, programming is the same. So some programmers have that creative flare, so in the way that writing a book is an art form, writing a really good computer program can be an art form too.

Number of reasons:

* Provides room for expansion when the building heats up. * Allows slack to move wires when remodeling. * Allows slack to reconnect wires when redoing terminations.

HTML files are most often sent and received using HTTP, which stands for HyperText Transfer Protocol. Files can also be shared using FTP, which stands for File Transfer Protocol.

These are dedicated lines used to coordinate data transfer. They are used to signal ready/not ready, or to acknowledge or request. This back and forth handshaking is needed in async comms to avoid sending data until the receiver is ready for it.

The MPU and peripherals operate at different speeds, the MPU being faster than the peripherals(like printers and data converters). To avoid overlapping of data during data input (by preventing MPU reading same data twice before i/p peripheral writes next data) or data output (by preventing MPU from writing over the data before o/p device has had a chance to accept it), handshake signals are used between MPU & the peripherals. These signals are generally provided by programmable devices.

Binary is a base 2 number system, while octal is base 8. This happens to make conversion between binary and octal fairly trivial, although more complex than conversion to hexadecimal. To convert to octal from binary, take each three bits, starting from the least significant bit, and convert them to their octal equivalent.

Examples:

25510 = 111111112 = 11 111 111 = 3778

17410 = 101011102 = 10 101 110 = 2568

You can repeat this process for as many bits as you need. A 24-bit number should translate into 8 octal numbers, for reference.

The weaknesses of static (or stateless) packet filters and stateful packet filters are different in a few ways. Stateless packet filters frequently block SYN scans of networks, but ....

Stateless packet filters. (cf. iptables connection tracking), cf. state vs. stateless discussion.

confounded application layer protocols like FTP, H323

Because of the nature of connection tracking and state awareness, stateful packet filters are vulnerable to resource exhaustion and deliberate attempts to trip rate-limiting features.

routers move data from one network to another network. For it to do so, it needs an IP address in both networks.

Detection of errors and retransmission of frames that are received in error.

It depends on what kind of files you're transferring, but you could use a virtual private network. Companies like USA Broadcast Services offer secure file transfers, so if you have large or a lot of files, they can definitely help you.

The F5 load balancer is designed to avoid overloading servers. It helps defend against attacks and inspects IP addresses to determine the most efficient data centers.

Typically, space-division multiplexing (SDM) is realized through a set number of frequency bands. This is combined with FDM because cells neighboring those in the SDM are unable to share the same frequencies.
