In higher education, a comprehensive examination (or comprehensive exam or exams), often abbreviated as comps, is a specific type of examination that must be completed by graduate students in some disciplines and courses of study, and also by undergraduate students in some institutions and departments.
Long-Term Evolution (LTE) is a standard for high-speed wireless communication for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements.
Basically, there is 4G and 4G LTE. Many people consider LTE to be true 4G technology. Generally, if a cellular provider describes a 4G network without mentioning LTE, they are probably talking about a High Speed Packet Access (HSPA) network. The HSPA network is a faster version of the 3G GSM network.
