The decision as to which of these client types an organization will use depends on their current network, client environment, security requirements, and whether or not the organization will be running all or just a few applications from the XenApp environment (the hybrid environment is discussed in 5). Table 15-1 compares the features and options of some of the more common ICA clients. The latest and most detailed version of this table can be found at http://download2.citrix.com/FILES/en/products/ ClientFeatMatrix/Citrix_ClientFeatureMatrix.pdf. As you can see there are a lot of choices to pick from, but for the scope of this book we discuss the Windows clients only.

NOTE It is unusual for risk treatment to eliminate risk altogether; rather, various controls are implemented that remove some of the risk. Often, management implicitly accepts the leftover risk; however, it s a good idea to make that acceptance of residual risk more formal by documenting the acceptance in a risk management log or a decision log.

If you go to a four-year school you ll get a traditional university education. This will require that you take classes in a variety of areas: the natural and applied sciences, the social sciences, and the humanities. Most schools will also have a basic writing requirement, and some will have a foreign language requirement as well. After a certain amount of general study, you ll declare a major and start concentrating on your particular field of interest. If you choose to go this route, I would recommend against any university that emphasizes only the liberal arts and does not have any engineering or technical facilities at all. If you re planning to be a composer, you may not care, but ideally you should be working with technological tools throughout your college education.

Figure 10-2: A higher speed Frame Relay connection The next step was to use a different device to access the high-speed connection on a Frame Relay network. Devices known as Frame Relay Access Devices (FRADs) were introduced to provide the access. This was done through a high-speed CSU/DSU, through a multiplexer, or some form of a switching system. The FRAD enabled the access to be simplified for the end user and the network provider alike. In Figure 10-3 , the FRAD is shown. Note the FRAD used here is through a CSU/DSU on one end and a high-speed T3 multiplexer on the far end. The choices vary for the end user, so the flexibility of the access is one of the strong points for the Frame Relay network.

What is meconium How often is meconium noted before or during delivery What are some of the causes of meconium passage in utero Fetal feces released into the amniotic fluid 10 15% of births Placental insufficiency Cord compression Infection What is meconium aspiration syndrome (MAS) A chemical pneumonitis caused by inhalation of meconium into the fetal tracheobronchial tree during the antepartum or intrapartum period Respiratory distress, persistent pulmonary hypertension, death

Notice that the keys and values contained within the collection are available as separate lists through the Keys and Values properties. IDictionary<TK, TV> defines the following indexer: TV this[TK key] { get; set; } You can use this indexer to get or set the value of an element. You can also use it to add a new element to the collection. Notice that the index is not actually an index, but rather the key of the item.

Because computer memory and data storage usually are measured in megabytes and gigabytes (as opposed to millions of bytes and billions of bytes), this book uses 1024 as the basis for measurements of data size and data capacity, with abbreviations of KB, MB, and GB. However, since these abbreviations have become so ambiguous, the term is spelled out when practical. In cases where it is necessary to be consistent with published numbers based on the alternative usage, the words thousand, million, and billion are used, or the abbreviations k bytes, M bytes, and G bytes are used (note the small k and the spaces). To distinguish kilobytes (1024 bytes) from other units such as kilometers (1000 meters), common practice is to use a large K for binary multiples. Unfortunately, other abbreviations such as M (mega) and m (micro) are already differentiated by case, so the convention cannot be applied uniformly to binary data storage. And in any case, too few people pay attention to these nuances. In 1999, the International Electrotechnical Commission (IEC) produced new prefixes for binary multiples3 (see Table I.1). Although the new prefixes have not caught on, they are a valiant effort to solve the problem. The main strike against them is that they sound a bit silly. For example, the prefix for the new term gigabinary is gibi, so a BD-25 can be said to hold 23.28 gibibytes, or GiB. The prefix for kilobinary is kibi, and the prefix for terabinary is tebi, yielding kibibytes and tebibytes. Jokes about kibbles and bits and teletebis are inevitable. As if all this were not complicated enough, data transfer rates, when measured in bits per second, are almost always multiples of 1000, but when measured in bytes per second
